The legality of using the IEEPA to tariff imports has been in question since the taxes were announced last year; the IEEPA was used to try to justify steep tariffs on Canada, Mexico, and China, as well as so-called “reciprocal” tariffs applied to goods coming into the US from just about every other country on Earth. The IEEPA was also invoked to end the de minimis exemption, which allowed for packages under a certain value to enter the US duty-free.Other tariffs imposed outside of the IEEPA — like those on steel and aluminum and other industry-specific taxes — won’t find relief from Friday’s Supreme Court ruling. Additionally, the Trump administration is looking for other ways to impose tariffs: At a press briefing on Friday, Trump railed against the Supreme Court justices while praising dissenting Justice Brett Kavanaugh, and he vowed to levy additional blanket tariffs and open investigations into unfair trade practices in the future.“Bottom line, industry should expect a continued high tariff environment for the foreseeable future.”It’s still unclear what this will mean for importers, small businesses, and consumers who have paid billions in taxes as a result of Trump’s tariffs — the ruling does not directly address how refunds would work, if at all. In his dissent, Kavanaugh notes that the US Treasury may be required to refund importers who paid tariffs under the IEEPA, and that the process to return the money could be a “mess.” The New York Times reports that refund requests could total $120 billion, although consumers, who are often the party ultimately paying for tariffs, are unlikely to get that money back. Monica Gorman, managing director at Crowell Global Advisors who worked on manufacturing under Joe Biden, told The Verge in an email that the issue will now go to the Court of International Trade and could take months to sort out.“The president has announced Section 122 tariffs effective almost immediately at a 10 percent rate. Although the 122 statute is limited to 150 days without a subsequent act of Congress, this will buy time for the administration to pursue additional tariff actions under Section 301 and other tariff statutes,” Gorman said. “Bottom line, industry should expect a continued high tariff environment for the foreseeable future.”The National Retail Federation said the decision “provides much-needed certainty for US businesses and manufacturers,” and called for “a seamless process to refund the tariffs to U.S. importers.”Small businesses were some of the first and most vocal opponents of Trump’s tariffs, and US-based companies relying on components and parts from abroad sounded the alarm early on. We Pay the Tariffs, a coalition of hundreds of small businesses, issued a statement celebrating the ruling but cautioned that “a legal victory is meaningless without actual relief for the businesses that paid these tariffs.“The administration’s only responsible course of action now is to establish a fast, efficient, and automatic refund process that returns tariff money to the businesses that paid it. Small businesses cannot afford to wait months or years while bureaucratic delays play out, nor can they afford expensive litigation just to recover money that was unlawfully collected from them in the first place. These businesses need their money back now.”RelatedThe great tariff shakedownAmazon’s CEO says tariffs are starting to ‘creep into’ pricingFrom the beginning, Trump used tariffs as a cudgel for obedience from foreign governments and big corporations, meaning the taxes were both massively disruptive and subject to change at any moment, especially if a party rolled over for the administration.

Now, we’re in a new era of uncertainty but with different questions — some consumers and businesses will want to once again stock up for an unclear future.To be sure, the SCOTUS decision is a blow to Trump’s agenda, but businesses and consumers are still living in a trade nightmare of the president’s own making: The Port of Los Angeles told CNN it’s expecting an influx of cargo ships as American importers rush to bring inventory into the country. Kathryn Anne Edwards, economist and policy consultant, told The Verge in an email that there’s still uncertainty after the ruling.“Taking control of tariffs out of [Trump’s] hands is unequivocally good for the economy,” she said. “That’s not to say the ruling won’t cause harm, but he was using the American consumer as leverage.”As economists warned, the American consumer is likely to foot the bill — for future tariffs imposed by Trump, for refunds, and for a new normal of higher prices that companies have no reason to roll back.“I think the political blowback could be incredible, given that companies are poised to see a refund, but consumers are not,” Edwards said.

Contents MeWe MeWe is a global social media and social networking service. As a company based in Los Angeles, California, it is also known as Sgrouples, Inc., doing business as MeWe. The site has been described as a Facebook alternative due to its focus on data privacy. In 2022, MeWe announced it will migrate its platform over time to a blockchain-based system. Platform In March 2020, MeWe launched dual-camera videos, which allow for both inward ("selfie") and outward-facing camera views. MeWe also touts its "Privacy Bill of Rights" as the primary differentiator between it and Facebook. By 2015, as MeWe neared the end of its beta testing cycle, the press called MeWe's software "not dissimilar to Facebook". In 2020, Mashable described MeWe as replicating Facebook's features. The MeWe site and application has features common to most social media and social networking sites: users can post text and images to a feed, react to others' posts using emoji, post animated GIFs, create specialized groups, post disappearing content, and chat. Online chat may occur between two or more people or among members of a group. Person-to-person online chat is similar to that in most other social media and social networking sites, and supports text, video calling, and voice calling. No longer a product offering, "Secret Chat" is limited to the paid subscription tier of MeWe, and uses double ratchet encryption to ensure that chats are private and not visible even to MeWe employees. MeWe reported in June 2018 that the site had 90,000 active groups, 60,000 of which were "public" and open to all users. Following the influx of Hong Kong users in 2020, MeWe's former CEO, Mark Weinstein, announced that the website would provide a Traditional Chinese language version by the end of the year. Although MeWe has not intentionally positioned itself as a social network for conservatives, Mashable noted in November 2020 that its active userbase trends conservative. The platform's choice not to moderate misinformation on the platform has attracted conservatives who felt mainstream social networks were censoring their posts, and those who have been banned from those platforms. MeWe is considered an alt-tech platform. MeWe's loose moderation has made it popular among conspiracy theorists, including proponents of the far-right QAnon conspiracy theory, which was banned from Facebook in 2020, and the "Stop the Steal" conspiracy theory relating to the 2020 United States presidential election. According to Rolling Stone, MeWe has "played host to general interest communities related to music and travel, but it has also come to be a haven for anti-vaxxers, QAnon conspiracy theorists, and, as reported by OneZero, far-right militia groups." Vice has described MeWe as a "major anti-vaxx forum". BBC News has described some of the content on MeWe as "extreme" and compared it to that of Gab. Business Insider has reported that some of the most popular groups on MeWe focus on "extreme views, like anti-vaccine rhetoric, white supremacy, and conspiracy theories" and that in 2020 the platform was used to organize anti-lockdown protests. According to Megan Squire, groups belonging to the Boogaloo movement began using the platform after their removal from Facebook. Shortly after the 2020 United States presidential election, MeWe and other alt-tech platforms experienced a wave of signups from Trump supporters, following crackdowns on election-related misinformation and promotion of violence on mainstream social networks. On November 11, MeWe was the second-most downloaded free app on the Apple App Store, behind its fellow alt-tech social network Parler. However, Mashable noted MeWe's practice of creating accounts on behalf of users and businesses who were not users of the site may have served to inflate the amount of activity on the platform. MeWe and other alt-tech networks again spiked in popularity shortly after the January 6, 2021 storming of the United States Capitol, though this subsided shortly after, with downloads falling more than 80% from January to February 2021. On January 22, 2021, MeWe's CEO said in an interview with NPR that "MeWe is serious about putting limits on what people can say" and that he does not like sites where "anything goes", describing such sites as "disgusting". He also said that MeWe would be hiring more moderation staff. In the coverage, NPR noted that MeWe's stated rules are still "more lax than Facebook and Twitter," and that MeWe had not yet banned groups dedicated to QAnon. Due to concerns surrounding possible pro-China censorship of Facebook, the site also gained popularity in Hong Kong in November 2020. MeWe gained popularity in Hong Kong in November 2020, with users migrating from Facebook due to concerns with possible pro-China censorship and moderation. The popularity of MeWe in Hong Kong has been attributed to the city's suspicion of any restraint on free speech, after the Chinese government imposed significant restrictions on the expression of dissent following the 2019–20 protests, including the Hong Kong national security law. MeWe communities in Hong Kong generally reflect everyday-life interests, with social media consultants in Hong Kong reporting that they have not seen extremist content in the communities they manage. Reception In a 2015 review of the beta MeWe service, British writer John Leonard called MeWe "well-designed and pretty intuitive", but questioned whether the company's business model was a viable one. Andrew Orr, reviewing the site in April 2018, felt that service was a good one but that it did not have any advantages over existing social media sites. That, he felt, would make it difficult for MeWe to attract users. In late 2020, the site also gained popularity in Hong Kong due to concerns surrounding possible pro-China censorship of Facebook. MeWe takes a relatively light approach to content moderation according to some sources. In 2022, MeWe announced it will migrate its platform over time to a Web3, blockchain-based web infrastructure using Project Liberty's DSNP and Frequency protocol, which will run on the Polkadot Blockchain Network, and make MeWe the largest decentralized social media platform. Business The MeWe business model does not rely on advertising revenue; rather, MeWe generates revenue from MeWe Premium subscriptions and from users purchasing premium enhancements a-la-carte such as a live voice / live video calling, extra storage, custom emojis, and custom themes. MeWe emphasizes its commitment to privacy and remaining ad-free. MeWe has said they will never use cookies or spyware to generate content about users, and that it will not track user activity in any way or sell user data to a third party. MeWe has described itself as the "anti-Facebook" due to its focus on data privacy, lack of moderation, and simple newsfeed algorithm. MeWe had 20 million registered users. Advisors to MeWe include computer scientist Tim Berners-Lee, Apple co-founder Steve Wozniak, SumZero CEO and co-founder of HarvardConnection Divya Narendra, and filmmaker Cullen Hoback. In 1998, entrepreneur Mark Weinstein and Jonathan Wolfe established SuperGroups.com, a social media website. The site was closed by its largest investor in 2001. Gathering largely the same leadership team, Weinstein incorporated Sgrouples Inc. in 2011. MeWe was incorporated as a subsidiary of Sgrouples, and based in Culver City, California. Over the next six years, Sgrouples raised about $10 million from investors including lynda.com founder Lynda Weinman, fashion designer Rachel Roy, and authors Jack Canfield and Marci Shimoff. MeWe finished its initial financing round in July 2018 by raising $5.2 million in new funds. The company began work on upgrading MeWe and initiating work on an enterprise version called MeWePRO. In December 2019, MeWe launched "MeWe Premium", an optional $4.99 per month subscription that gives users a bundle of enhancements including: live voice / live video calling; unlimited custom themes; unlimited custom emojis and stickers; video journals for stories; 100GB of MeWe Cloud Storage; and more. In September 2022, CEO Jeffrey Scott Edell of MeWe announced that it had raised $27 million in a Series A round led by private company McCourt Global, which contributed $15 million. Existing investors contributed another $12 million—this round values MeWe at approximately $200 million. Mark Weinstein was a founder of MeWe and its CEO until April 2021. Jeffrey Scott Edell replaced him as CEO in 2021. Carlos Betancourt became CEO in 2025. References |

Contents PlayStation (console) The PlayStation[a] (codenamed PSX, abbreviated as PS, and retroactively PS1 or PS one) is a home video game console developed and marketed by Sony Computer Entertainment. It was released in Japan on 3 December 1994, followed by North America on 9 September 1995, Europe on 29 September 1995, and other regions following thereafter. As a fifth-generation console, the PlayStation primarily competed with the Nintendo 64 and the Sega Saturn. Sony began developing the PlayStation after a failed venture with Nintendo to create a CD-ROM peripheral for the Super Nintendo Entertainment System in the early 1990s. The console was primarily designed by Ken Kutaragi and Sony Computer Entertainment in Japan, while additional development was outsourced in the United Kingdom. An emphasis on 3D polygon graphics was placed at the forefront of the console's design. PlayStation game production was designed to be streamlined and inclusive, enticing the support of many third party developers. The console proved popular for its extensive game library, popular franchises, low retail price, and aggressive youth marketing which advertised it as the preferable console for adolescents and adults. Critically acclaimed games that defined the console include Gran Turismo, Crash Bandicoot, Spyro the Dragon, Tomb Raider, Resident Evil, Metal Gear Solid, Tekken 3, and Final Fantasy VII. Sony ceased production of the PlayStation on 23 March 2006—over eleven years after it had been released, and in the same year the PlayStation 3 debuted. More than 4,000 PlayStation games were released, with cumulative sales of 962 million units. The PlayStation signaled Sony's rise to power in the video game industry. It received acclaim and sold strongly; in less than a decade, it became the first computer entertainment platform to ship over 100 million units. Its use of compact discs heralded the game industry's transition from cartridges. The PlayStation's success led to a line of successors, beginning with the PlayStation 2 in 2000. In the same year, Sony released a smaller and cheaper model, the PS one. History The PlayStation was conceived by Ken Kutaragi, a Sony executive who managed a hardware engineering division and was later dubbed "the Father of the PlayStation". Kutaragi's interest in working with video games stemmed from seeing his daughter play games on Nintendo's Famicom. Kutaragi convinced Nintendo to use his SPC-700 sound processor in the Super Nintendo Entertainment System (SNES) through a demonstration of the processor's capabilities. His willingness to work with Nintendo was derived from both his admiration of the Famicom and conviction in video game consoles becoming the main home-use entertainment systems. Although Kutaragi was nearly fired because he worked with Nintendo without Sony's knowledge, president Norio Ohga recognised the potential in Kutaragi's chip and decided to keep him as a protégé. The inception of the PlayStation dates back to a 1988 joint venture between Nintendo and Sony. Nintendo had produced floppy disk technology to complement cartridges in the form of the Family Computer Disk System, and wanted to continue this complementary storage strategy for the SNES. Since Sony was already contracted to produce the SPC-700 sound processor for the SNES, Nintendo contracted Sony to develop a CD-ROM add-on, tentatively titled the "Play Station" or "SNES-CD". The PlayStation name had already been trademarked by Yamaha, but Nobuyuki Idei liked it so much that he agreed to acquire it for an undisclosed sum rather than search for an alternative. Sony was keen to obtain a foothold in the rapidly expanding video game market. Having been the primary manufacturer of the MSX home computer format, Sony had wanted to use their experience in consumer electronics to produce their own video game hardware. Although the initial agreement between Nintendo and Sony was about producing a CD-ROM drive add-on, Sony had also planned to develop a SNES-compatible Sony-branded console. This iteration was intended to be more of a home entertainment system, playing both SNES cartridges and a new CD format named the "Super Disc", which Sony would design. Under the agreement, Sony would retain sole international rights to every Super Disc game, giving them a large degree of control despite Nintendo's leading position in the video game market. Furthermore, Sony would also be the sole benefactor of licensing related to music and film software that it had been aggressively pursuing as a secondary application. The Play Station was to be announced at the 1991 Consumer Electronics Show (CES) in Las Vegas. However, Nintendo president Hiroshi Yamauchi was wary of Sony's increasing leverage at this point and deemed the original 1988 contract unacceptable upon realising it essentially handed Sony control over all games written on the SNES CD-ROM format. Although Nintendo was dominant in the video game market, Sony possessed a superior research and development department. Wanting to protect Nintendo's existing licensing structure, Yamauchi cancelled all plans for the joint Nintendo–Sony SNES CD attachment without telling Sony. He sent Nintendo of America president Minoru Arakawa (his son-in-law) and chairman Howard Lincoln to Amsterdam to form a more favourable contract with Dutch conglomerate Philips, Sony's rival. This contract would give Nintendo total control over their licences on all Philips-produced machines. Kutaragi and Nobuyuki Idei, Sony's director of public relations at the time, learned of Nintendo's actions two days before the CES was due to begin. Kutaragi telephoned numerous contacts, including Philips, to no avail. On the first day of the CES, Sony announced their partnership with Nintendo and their new console, the Play Station. At 9 am on the next day, in what has been called "the greatest ever betrayal" in the industry, Howard Lincoln stepped onto the stage and revealed that Nintendo was now allied with Philips and would abandon their work with Sony. Incensed by Nintendo's renouncement, Ohga and Kutaragi decided that Sony would develop their own console. Nintendo's contract-breaking was met with consternation in the Japanese business community, as they had broken an "unwritten law" of native companies not turning against each other in favour of foreign ones. Sony's American branch considered allying with Sega to produce a CD-ROM-based machine called the Sega Multimedia Entertainment System, but the Sega board of directors in Tokyo vetoed the idea when Sega of America CEO Tom Kalinske presented them the proposal. Kalinske recalled them saying: "That's a stupid idea, Sony doesn't know how to make hardware. They don't know how to make software either. Why would we want to do this?" Sony halted their research, but decided to develop what it had developed with Nintendo and Sega into a console based on the SNES. Despite the tumultuous events at the 1991 CES, negotiations between Nintendo and Sony were still ongoing. A deal was proposed: the Play Station would still have a port for SNES games, on the condition that it would still use Kutaragi's audio chip and that Nintendo would own the rights and receive the bulk of the profits. Roughly two hundred prototype machines were created, and some software entered development. Many within Sony were still opposed to their involvement in the video game industry, with some resenting Kutaragi for jeopardising the company. Kutaragi remained adamant that Sony not retreat from the growing industry and that a deal with Nintendo would never work. Knowing that they had to take decisive action, Sony severed all ties with Nintendo on 4 May 1992. To determine the fate of the PlayStation project, Ohga chaired a meeting in June 1992, consisting of Kutaragi and several senior Sony board members. Kutaragi unveiled a proprietary CD-ROM-based system he had been secretly working on which played games with immersive 3D graphics. Kutaragi was confident that his LSI chip could accommodate one million logic gates, which exceeded the capabilities of Sony's semiconductor division at the time. Despite gaining Ohga's enthusiasm, there remained opposition from a majority present at the meeting. Older Sony executives also opposed it, who saw Nintendo and Sega as "toy" manufacturers. The opposers felt the game industry was too culturally offbeat and asserted that Sony should remain a central player in the audiovisual industry, where companies were familiar with one another and could conduct "civili[s]ed" business negotiations. After Kutaragi reminded him of the humiliation he suffered from Nintendo, Ohga retained the project and became one of Kutaragi's most staunch supporters. Ohga shifted Kutaragi and nine of his team from Sony's main headquarters to Sony Music Entertainment Japan (SMEJ), a subsidiary of the main Sony group, so as to retain the project and maintain relationships with Philips for the MMCD development project. The involvement of SMEJ proved crucial to the PlayStation's early development as the process of manufacturing games on CD-ROM format was similar to that used for audio CDs, with which Sony's music division had considerable experience. While at SMEJ, Kutaragi worked with Epic/Sony Records founder Shigeo Maruyama and Akira Sato; both later became vice-presidents of the division that ran the PlayStation business. Sony Computer Entertainment (SCE) was jointly established by Sony and SMEJ to handle the company's ventures into the video game industry. On 27 October 1993, Sony publicly announced that it was entering the game console market with the PlayStation. According to Maruyama, there was uncertainty over whether the console should primarily focus on 2D, sprite-based graphics or 3D polygon graphics. After Sony witnessed the success of Sega's Virtua Fighter (1993) in Japanese arcades, the direction of the PlayStation became "instantly clear" and 3D polygon graphics became the console's primary focus. SCE president Teruhisa Tokunaka expressed gratitude for Sega's timely release of Virtua Fighter as it proved "just at the right time" that making games with 3D imagery was possible. Maruyama claimed that Sony further wanted to emphasise the new console's ability to utilise redbook audio from the CD-ROM format in its games alongside high quality visuals and gameplay. Wishing to distance the project from the failed enterprise with Nintendo, Sony initially branded the PlayStation the "PlayStation X" (PSX). Sony formed their European division and North American division, known as Sony Computer Entertainment Europe (SCEE) and Sony Computer Entertainment America (SCEA), in January and May 1995. The divisions planned to market the new console under the alternative branding "PSX" following the negative feedback regarding "PlayStation" in focus group studies. Early advertising prior to the console's launch in North America referenced PSX, but the term was scrapped before launch. The console was not marketed with Sony's name in contrast to Nintendo's consoles. According to Phil Harrison, much of Sony's upper management feared that the Sony brand would be tarnished if associated with the console, which they considered a "toy". Since Sony had no experience in game development, it had to rely on the support of third-party game developers. This was in contrast to Sega and Nintendo, which had versatile and well-equipped in-house software divisions for their arcade games and could easily port successful games to their home consoles. Recent consoles like the Atari Jaguar and 3DO suffered low sales due to a lack of developer support, prompting Sony to redouble their efforts in gaining the endorsement of arcade-savvy developers. A team from Epic Sony visited more than a hundred companies throughout Japan in May 1993 in hopes of attracting game creators with the PlayStation's technological appeal. Sony found that many disliked Nintendo's practices, such as favouring their own games over others. Through a series of negotiations, Sony acquired initial support from Namco, Konami, and Williams Entertainment, as well as 250 other development teams in Japan alone. Namco in particular was interested in developing for PlayStation since Namco rivalled Sega in the arcade market. Attaining these companies secured influential games such as Ridge Racer (1993) and Mortal Kombat 3 (1995), Ridge Racer being one of the most popular arcade games at the time, and it was already confirmed behind closed doors that it would be the PlayStation's first game by December 1993, despite Namco being a longstanding Nintendo developer. Namco's research managing director Shegeichi Nakamura met with Kutaragi in 1993 to discuss the preliminary PlayStation specifications, with Namco subsequently basing the Namco System 11 arcade board on PlayStation hardware and developing Tekken to compete with Virtua Fighter. The System 11 launched in arcades several months before the PlayStation's release, with the arcade release of Tekken in September 1994. Despite securing the support of various Japanese studios, Sony had no developers of their own by the time the PlayStation was in development. This changed in 1993 when Sony acquired the Liverpudlian company Psygnosis (later renamed SCE Liverpool) for US$48 million, securing their first in-house development team. The acquisition meant that Sony could have more launch games ready for the PlayStation's release in Europe and North America. Ian Hetherington, Psygnosis' co-founder, was disappointed after receiving early builds of the PlayStation and recalled that the console "was not fit for purpose" until his team got involved with it. Hetherington frequently clashed with Sony executives over broader ideas; at one point it was suggested that a television with a built-in PlayStation be produced. In the months leading up to the PlayStation's launch, Psygnosis had around 500 full-time staff working on games and assisting with software development. The purchase of Psygnosis marked another turning point for the PlayStation as it played a vital role in creating the console's development kits. While Sony had provided MIPS R4000-based Sony NEWS workstations for PlayStation development, Psygnosis employees disliked the thought of developing on these expensive workstations and asked Bristol-based SN Systems to create an alternative PC-based development system. Andy Beveridge and Martin Day, owners of SN Systems, had previously supplied development hardware for other consoles such as the Mega Drive, Atari ST, and the SNES. When Psygnosis arranged an audience for SN Systems with Sony's Japanese executives at the January 1994 CES in Las Vegas, Beveridge and Day presented their prototype of the condensed development kit, which could run on an ordinary personal computer with two extension boards. Impressed, Sony decided to abandon their plans for a workstation-based development system in favour of SN Systems's, thus securing a cheaper and more efficient method for designing software. An order of over 600 systems followed, and SN Systems supplied Sony with additional software such as an assembler, linker, and a debugger. SN Systems produced development kits for future PlayStation systems, including the PlayStation 2 and was bought out by Sony in 2005. Sony strived to make game production as streamlined and inclusive as possible, in contrast to the relatively isolated approach of Sega and Nintendo. Phil Harrison, representative director of SCEE, believed that Sony's emphasis on developer assistance reduced most time-consuming aspects of development. As well as providing programming libraries, SCE headquarters in London, California, and Tokyo housed technical support teams that could work closely with third-party developers if needed. Sony did not favour their own over non-Sony products, unlike Nintendo; Peter Molyneux of Bullfrog Productions admired Sony's open-handed approach to software developers and lauded their decision to use PCs as a development platform, remarking that "[it was] like being released from jail in terms of the freedom you have". Another strategy that helped attract software developers was the PlayStation's use of the CD-ROM format instead of traditional cartridges. Nintendo cartridges were expensive to manufacture, and the company controlled all production, prioritising their own games, while inexpensive compact disc manufacturing occurred at dozens of locations around the world. The PlayStation's architecture and interconnectability with PCs was beneficial to many software developers. The use of the programming language C proved useful, as it safeguarded future compatibility of the machine should developers decide to make further hardware revisions. Despite the inherent flexibility, some developers found themselves restricted due to the console's lack of RAM. While working on beta builds of the PlayStation, Molyneux observed that its MIPS processor was not "quite as bullish" compared to that of a fast PC and said that it took his team two weeks to port their PC code to the PlayStation development kits and another fortnight to achieve a four-fold speed increase. An engineer from Ocean Software, one of Europe's largest game developers at the time, thought that allocating RAM was a challenging aspect given the 3.5 megabyte restriction. Kutaragi said that while it would have been easy to double the amount of RAM for the PlayStation, the development team refrained from doing so to keep the retail cost down. Kutaragi saw the biggest challenge in developing the system to be balancing the conflicting goals of high performance, low cost, and being easy to program for, and felt he and his team were successful in this regard. Its technical specifications were finalised in 1993 and its design during 1994. The PlayStation name and its final design were confirmed during a press conference on May 10, 1994, although the price and release dates had not been disclosed yet. Sony released the PlayStation in Japan on 3 December 1994, a week after the release of the Sega Saturn, at a price of ¥39,800. Sales in Japan began with a "stunning" success with long queues in shops. Ohga later recalled that he realised how important PlayStation had become for Sony when friends and relatives begged for consoles for their children. PlayStation sold 100,000 units on the first day and two million units within six months, although the Saturn outsold the PlayStation in the first few weeks due to the success of Virtua Fighter. By the end of 1994, 300,000 PlayStation units were sold in Japan compared to 500,000 Saturn units. A grey market emerged for PlayStations shipped from Japan to North America and Europe, with buyers of such consoles paying up to £700. "When September 1995 arrived and Sony's Playstation roared out of the gate, things immediately felt different than [sic] they did with the Saturn launch earlier that year. Sega dropped the Saturn $100 to match the Playstation's $299 debut price, but sales weren't even close—Playstations flew out the door as fast as we could get them in stock. Before the release in North America, Sega and Sony presented their consoles at the first Electronic Entertainment Expo (E3) in Los Angeles on 11 May 1995. At their keynote presentation, Sega of America CEO Tom Kalinske revealed that their Saturn console would be released immediately to select retailers at a price of $399. Next came Sony's turn: Olaf Olafsson, the head of SCEA, summoned Steve Race, the head of development, to the conference stage, who said "$299" and left the audience with a round of applause. The attention to the Sony conference was further bolstered by the surprise appearance of Michael Jackson and the showcase of highly anticipated games, including Wipeout (1995), Ridge Racer and Tekken (1994). In addition, Sony announced that no games would be bundled with the console. Although the Saturn had released early in the United States to gain an advantage over the PlayStation, the surprise launch upset many retailers who were not informed in time, harming sales. Some retailers such as KB Toys responded by dropping the Saturn entirely. The PlayStation went on sale in North America on 9 September 1995. It sold more units within two days than the Saturn had in five months, with almost all of the initial shipment of 100,000 units sold in advance and shops across the country running out of consoles and accessories. The well-received Ridge Racer contributed to the PlayStation's early success, — with some critics considering it superior to Sega's arcade counterpart Daytona USA (1994) — as did Battle Arena Toshinden (1995). There were over 100,000 pre-orders placed and 17 games available on the market by the time of the PlayStation's American launch, in comparison to the Saturn's six launch games. The PlayStation released in Europe on 29 September 1995 and in Australia on 15 November 1995. By November it had already outsold the Saturn by three to one in the United Kingdom, where Sony had allocated a £20 million marketing budget during the Christmas season compared to Sega's £4 million. Sony found early success in the United Kingdom by securing listings with independent shop owners as well as prominent High Street chains such as Comet and Argos. Within its first year, the PlayStation secured over 20% of the entire American video game market. From September to the end of 1995, sales in the United States amounted to 800,000 units, giving the PlayStation a commanding lead over the other fifth-generation consoles,[b] though the SNES and Mega Drive from the fourth generation still outsold it. Sony reported that the attach rate of sold games and consoles was four to one. To meet increasing demand, Sony chartered jumbo jets and ramped up production in Europe and North America. By early 1996, the PlayStation had grossed $2 billion (equivalent to $4.106 billion 2025) from worldwide hardware and software sales. By late 1996, sales in Europe totalled 2.2 million units, including 700,000 in the UK. Approximately 400 PlayStation games were in development, compared to around 200 games being developed for the Saturn and 60 for the Nintendo 64. In India, the PlayStation was launched in test market during 1999–2000 across Sony showrooms, selling 100 units. Sony finally launched the console (PS One model) countrywide on 24 January 2002 with the price of Rs 7,990 and 26 games available from start. PlayStation was also doing well in markets where it was never officially released. For example, in Brazil, due to the registration of the trademark by a third company, the console could not be released, which was why the market was taken over by the officially distributed Sega Saturn during the first period, but as the Sega console withdraws, PlayStation imports and large piracy increased. In another market, China, the most popular 32-bit console was Sega Saturn, but after leaving the market, PlayStation grown with a base of 300,000 users until January 2000, although Sony China did not have plans to release it. The PlayStation was backed by a successful marketing campaign, allowing Sony to gain an early foothold in Europe and North America. Initially, PlayStation demographics were skewed towards adults, but the audience broadened after the first price drop. While the Saturn was positioned towards 18- to 34-year-olds, the PlayStation was initially marketed exclusively towards teenagers. Executives from both Sony and Sega reasoned that because younger players typically looked up to older, more experienced players, advertising targeted at teens and adults would draw them in too. Additionally, Sony found that adults reacted best to advertising aimed at teenagers; Lee Clow surmised that people who started to grow into adulthood regressed and became "17 again" when they played video games. The console was marketed with advertising slogans stylised as "LIVE IN YUR WRLD. PLY IN URS" (Live in Your World. Play in Ours.) and "U R NOT E" (red E). The four geometric shapes were derived from the symbols for the four buttons on the controller. Clow thought that by invoking such provocative statements, gamers would respond to the contrary and say "'Bullshit. Let me show you how ready I am.'" As the console's appeal enlarged, Sony's marketing efforts broadened from their earlier focus on mature players to specifically target younger children as well. Shortly after the PlayStation's release in Europe, Sony tasked marketing manager Geoff Glendenning with assessing the desires of a new target audience. Sceptical over Nintendo and Sega's reliance on television campaigns, Glendenning theorised that young adults transitioning from fourth-generation consoles would feel neglected by marketing directed at children and teenagers. Recognising the influence early 1990s underground clubbing and rave culture had on young people, especially in the United Kingdom, Glendenning felt that the culture had become mainstream enough to help cultivate PlayStation's emerging identity. Sony partnered with prominent nightclub owners such as Ministry of Sound and festival promoters to organise dedicated PlayStation areas where demonstrations of select games could be tested. Sheffield-based graphic design studio The Designers Republic was contracted by Sony to produce promotional materials aimed at a fashionable, club-going audience. Psygnosis' Wipeout in particular became associated with nightclub culture as it was widely featured in venues. By 1997, there were 52 nightclubs in the United Kingdom with dedicated PlayStation rooms. Glendenning recalled that he had discreetly used at least £100,000 a year in slush fund money to invest in impromptu marketing. In 1996, Sony expanded their CD production facilities in the United States due to the high demand for PlayStation games, increasing their monthly output from 4 million discs to 6.5 million discs. This was necessary because PlayStation sales were running at twice the rate of Saturn sales, and its lead dramatically increased when both consoles dropped in price to $199 that year. The PlayStation also outsold the Saturn at a similar ratio in Europe during 1996, with 2.2 million consoles sold in the region by the end of the year. Sales figures for PlayStation hardware and software only increased following the launch of the Nintendo 64. Tokunaka speculated that the Nintendo 64 launch had actually helped PlayStation sales by raising public awareness of the gaming market through Nintendo's added marketing efforts. Despite this, the PlayStation took longer to achieve dominance in Japan. Tokunaka said that, even after the PlayStation and Saturn had been on the market for nearly two years, the competition between them was still "very close", and neither console had led in sales for any meaningful length of time. By 1998, Sega, encouraged by their declining market share and significant financial losses, launched the Dreamcast as a last-ditch attempt to stay in the industry. Although its launch was successful, the technically superior 128-bit console was unable to subdue Sony's dominance in the industry. Sony still held 60% of the overall video game market share in North America at the end of 1999. Sega's initial confidence in their new console was undermined when Japanese sales were lower than expected, with disgruntled Japanese consumers reportedly returning their Dreamcasts in exchange for PlayStation software. On 2 March 1999, Sony officially revealed details of the PlayStation 2, which Kutaragi announced would feature a graphics processor designed to push more raw polygons than any console in history, effectively rivalling most supercomputers. The PlayStation continued to sell strongly at the turn of the new millennium: in June 2000, Sony released the PSOne, a smaller, redesigned variant which went on to outsell all other consoles in that year, including the PlayStation 2. In 2005, PlayStation became the first console to ship 100 million units with the PlayStation 2 later achieving this faster than its predecessor. The combined successes of both PlayStation consoles led to Sega retiring the Dreamcast in 2001, and abandoning the console business entirely. The PlayStation was eventually discontinued on 23 March 2006—over eleven years after its release, and less than a year before the debut of the PlayStation 3. Hardware The main microprocessor is a R3000 CPU made by LSI Logic operating at a clock rate of 33.8688 MHz and 30 MIPS. This 32-bit CPU relies heavily on the "cop2" 3D and matrix math coprocessor on the same die to provide the necessary speed to render complex 3D graphics. The role of the separate GPU chip is to draw 2D polygons and apply shading and textures to them: the rasterisation stage of the graphics pipeline. Sony's custom 16-bit sound chip supports ADPCM sources with up to 24 sound channels and offers a sampling rate of up to 44.1 kHz and music sequencing. It features 2 MB of main RAM, with an additional 1 MB of video RAM. The PlayStation has a maximum colour depth of 16.7 million true colours with 32 levels of transparency and unlimited colour look-up tables. The PlayStation can output composite, S-Video or RGB video signals through its AV Multi connector (with older models also having RCA connectors for composite), displaying resolutions from 256×224 to 640×480 pixels. Different games can use different resolutions. Earlier models also had proprietary parallel and serial ports that could be used to connect accessories or multiple consoles together; these were later removed due to a lack of usage. The PlayStation uses a proprietary video compression unit, MDEC, which is integrated into the CPU and allows for the presentation of full motion video at a higher quality than other consoles of its generation. Unusual for the time, the PlayStation lacks a dedicated 2D graphics processor; 2D elements are instead calculated as polygons by the Geometry Transfer Engine (GTE) so that they can be processed and displayed on screen by the GPU. While running, the GPU can also generate a total of 4,000 sprites and 180,000 polygons per second, in addition to 360,000 per second flat-shaded. The PlayStation went through a number of variants during its production run. Externally, the most notable change was the gradual reduction in the number of external connectors from the rear of the unit. This started with the original Japanese launch units; the SCPH-1000, released on 3 December 1994, was the only model that had an S-Video port, as it was removed from the next model. Subsequent models saw a reduction in number of parallel ports, with the final version only retaining one serial port. Sony marketed a development kit for amateur developers known as the Net Yaroze (meaning "Let's do it together" in Japanese). It was launched in June 1996 in Japan, and following public interest, was released the next year in other countries. The Net Yaroze allowed hobbyists to create their own games and upload them via an online forum run by Sony. The console was only available to buy through an ordering service and with the necessary documentation and software to program PlayStation games and applications through C programming compilers. On 7 July 2000, Sony released the PS One (stylised as "PS one" or "PSone"), a smaller, redesigned version of the original PlayStation. It was the highest-selling console through the end of the year, outselling all other consoles—including the PlayStation 2. In 2002, Sony released a 5-inch (130 mm) LCD screen add-on for the PS One, referred to as the "Combo pack". It also included a car cigarette lighter adaptor adding an extra layer of portability. Production of the LCD "Combo Pack" ceased in 2004, when the popularity of the PlayStation began to wane in markets outside Japan. A total of 28.15 million PS One units had been sold by the time it was discontinued in March 2006. Three iterations of the PlayStation's controller were released over the console's lifespan. The first controller, the PlayStation controller, was released alongside the PlayStation in December 1994. It features four individual directional buttons (as opposed to a conventional D-pad), a pair of shoulder buttons on both sides, Start and Select buttons in the centre, and four face buttons consisting of simple geometric shapes: a green triangle, red circle, blue cross, and a pink square (, , , ). Rather than depicting traditionally used letters or numbers onto its buttons, the PlayStation controller established a trademark which would be incorporated heavily into the PlayStation brand. Teiyu Goto, the designer of the original PlayStation controller, said that the circle and cross represent "yes" and "no", respectively (though this layout is reversed in Western versions); the triangle symbolises a point of view and the square is equated to a sheet of paper to be used to access menus. The European and North American models of the original PlayStation controllers are roughly 10% larger than its Japanese variant, to account for the fact the average person in those regions has larger hands than the average Japanese person. Sony's first analogue gamepad, the PlayStation Analog Joystick (often erroneously referred to as the "Sony Flightstick"), was first released in Japan in April 1996. Featuring two parallel joysticks, it uses potentiometer technology previously used on consoles such as the Vectrex; instead of relying on binary eight-way switches, the controller detects minute angular changes through the entire range of motion. The stick also features a thumb-operated digital hat switch on the right joystick, corresponding to the traditional D-pad, and used for instances when simple digital movements were necessary. The Analog Joystick sold poorly in Japan due to its high cost and cumbersome size. The increasing popularity of 3D games prompted Sony to add analogue sticks to its controller design to give users more freedom over their movements in virtual 3D environments. The first official analogue controller, the Dual Analog Controller, was revealed to the public in a small glass booth at the 1996 PlayStation Expo in Japan, and released in April 1997 to coincide with the Japanese releases of analogue-capable games Tobal 2 and Bushido Blade. In addition to the two analogue sticks (which also introduced two new buttons mapped to clicking in the analogue sticks), the Dual Analog controller features an "Analog" button and LED beneath the "Start" and "Select" buttons which toggles analogue functionality on or off. The controller also features rumble support, though Sony decided that haptic feedback would be removed from all overseas iterations before the United States release. A Sony spokesman stated that the feature was removed for "manufacturing reasons", although rumours circulated that Nintendo had attempted to legally block the release of the controller outside Japan due to similarities with the Nintendo 64 controller's Rumble Pak. However, a Nintendo spokesman denied that Nintendo took legal action. Next Generation's Chris Charla theorised that Sony dropped vibration feedback to keep the price of the controller down. In November 1997, Sony introduced the DualShock controller. Its name derives from its use of two (dual) vibration motors (shock). Unlike its predecessor, its analogue sticks feature textured rubber grips, longer handles, slightly different shoulder buttons and has rumble feedback included as standard on all versions. The DualShock later replaced its predecessors as the default controller. Sony released a series of peripherals to add extra layers of functionality to the PlayStation. Such peripherals include memory cards, the PlayStation Mouse, the PlayStation Link Cable, the Multiplayer Adapter (a four-player multitap), the Memory Drive (a disk drive for 3.5-inch floppy disks), the GunCon (a light gun), and the Glasstron (a monoscopic head-mounted display). Released exclusively in Japan, the PocketStation is a memory card peripheral which acts as a miniature personal digital assistant. The device features a monochrome liquid crystal display (LCD), infrared communication capability, a real-time clock, built-in flash memory, and sound capability. Sharing similarities with the Dreamcast's VMU peripheral, the PocketStation was typically distributed with certain PlayStation games, enhancing them with added features. The PocketStation proved popular in Japan, selling over five million units. Sony planned to release the peripheral outside Japan but the release was cancelled, despite receiving promotion in Europe and North America. In addition to playing games, most PlayStation models are equipped to play CD-Audio. The Asian model SCPH-5903 can also play Video CDs. Like most CD players, the PlayStation can play songs in a programmed order, shuffle the playback order of the disc and repeat one song or the entire disc. Later PlayStation models use a music visualisation function called SoundScope. This function, as well as a memory card manager, is accessed by starting the console without either inserting a game or closing the CD tray, thereby accessing a graphical user interface (GUI) for the PlayStation BIOS. The GUI for the PS One and PlayStation differ depending on the firmware version: the original PlayStation GUI had a dark blue background with rainbow graffiti used as buttons, while the early PAL PlayStation and PS One GUI had a grey blocked background with two icons in the middle. PlayStation emulation is versatile and can be run on numerous modern devices. Bleem! was a commercial emulator which was released for IBM-compatible PCs and the Dreamcast in 1999. It was notable for being aggressively marketed during the PlayStation's lifetime, and was the centre of multiple controversial lawsuits filed by Sony. Bleem! was programmed in assembly language, which allowed it to emulate PlayStation games with improved visual fidelity, enhanced resolutions, and filtered textures that was not possible on original hardware. Sony sued Bleem! two days after its release, citing copyright infringement and accusing the company of engaging in unfair competition and patent infringement by allowing use of PlayStation BIOSs on a Sega console. Bleem! were subsequently forced to shut down in November 2001. Sony was aware that using CDs for game distribution could have left games vulnerable to piracy, due to the growing popularity of CD-R and optical disc drives with burning capability. To preclude illegal copying, a proprietary process for PlayStation disc manufacturing was developed that, in conjunction with an augmented optical drive in Tiger H/E assembly, prevented burned copies of games from booting on an unmodified console. Specifically, all genuine PlayStation discs were printed with a small section of deliberate irregular data, which the PlayStation's optical pick-up was capable of detecting and decoding. Consoles would not boot game discs without a specific wobble frequency contained in the data of the disc pregap sector (the same system was also used to encode discs' regional lockouts). This signal was within Red Book CD tolerances, so PlayStation discs' actual content could still be read by a conventional disc drive; however, the disc drive could not detect the wobble frequency (therefore duplicating the discs omitting it), since the laser pick-up system of any optical disc drive would interpret this wobble as an oscillation of the disc surface and compensate for it in the reading process. Early PlayStations, particularly early 1000 models, experience skipping full-motion video or physical "ticking" noises from the unit. The problems stem from poorly placed vents leading to overheating in some environments, causing the plastic mouldings inside the console to warp slightly and create knock-on effects with the laser assembly. The solution is to sit the console on a surface which dissipates heat efficiently in a well vented area or raise the unit up slightly from its resting surface. Sony representatives also recommended unplugging the PlayStation when it is not in use, as the system draws in a small amount of power (and therefore heat) even when turned off. The first batch of PlayStations use a KSM-440AAM laser unit, whose case and movable parts are all built out of plastic. Over time, the plastic lens sled rail wears out—usually unevenly—due to friction. The placement of the laser unit close to the power supply accelerates wear, due to the additional heat, which makes the plastic more vulnerable to friction. Eventually, one side of the lens sled will become so worn that the laser can tilt, no longer pointing directly at the CD; after this, games will no longer load due to data read errors. Sony fixed the problem by making the sled out of die-cast metal and placing the laser unit further away from the power supply on later PlayStation models. Due to an engineering oversight, the PlayStation does not produce a proper signal on several older models of televisions, causing the display to flicker or bounce around the screen. Sony decided not to change the console design, since only a small percentage of PlayStation owners used such televisions, and instead gave consumers the option of sending their PlayStation unit to a Sony service centre to have an official modchip installed, allowing play on older televisions. Game library The PlayStation featured a diverse game library which grew to appeal to all types of players. Critically acclaimed PlayStation games included Final Fantasy VII (1997), Crash Bandicoot (1996), Spyro the Dragon (1998), Metal Gear Solid (1998), all of which became established franchises. Final Fantasy VII is credited with allowing role-playing games to gain mass-market appeal outside Japan, and is considered one of the most influential and greatest video games ever made. The PlayStation's bestselling game is Gran Turismo (1997), which sold 10.85 million units. After the PlayStation's discontinuation in 2006, the cumulative software shipment was 962 million units. Following its 1994 launch in Japan, early games included Ridge Racer, Crime Crackers, King's Field, Motor Toon Grand Prix, Toh Shin Den (i.e. Battle Arena Toshinden), and Kileak: The Blood. The first two games available at its later North American launch were Jumping Flash! (1995) and Ridge Racer, with Jumping Flash! heralded as an ancestor for 3D graphics in console gaming. Wipeout, Air Combat, Twisted Metal, Warhawk and Destruction Derby were among the popular first-year games, and the first to be reissued as part of Sony's Greatest Hits or Platinum range. At the time of the PlayStation's first Christmas season, Psygnosis had produced around 70% of its launch catalogue; their breakthrough racing game Wipeout was acclaimed for its techno soundtrack and helped raise awareness of Britain's underground music community. Eidos Interactive's action-adventure game Tomb Raider contributed substantially to the success of the console in 1996, with its main protagonist Lara Croft becoming an early gaming icon and garnering unprecedented media promotion. Licensed tie-in video games of popular films were also prevalent; Argonaut Games' 2001 adaptation of Harry Potter and the Philosopher's Stone went on to sell over eight million copies late in the console's lifespan. Third-party developers committed largely to the console's wide-ranging game catalogue even after the launch of the PlayStation 2; some of the notable exclusives in this era include Harry Potter and the Philosopher's Stone, Fear Effect 2: Retro Helix, Syphon Filter 3, C-12: Final Resistance, Dance Dance Revolution Konamix and Digimon World 3.[c] Sony assisted with game reprints as late as 2008 with Metal Gear Solid: The Essential Collection, this being the last PlayStation game officially released and licensed by Sony. Initially, in the United States, PlayStation games were packaged in long cardboard boxes, similar to non-Japanese 3DO and Saturn games. Sony later switched to the jewel case format typically used for audio CDs and Japanese video games, as this format took up less retailer shelf space (which was at a premium due to the large number of PlayStation games being released), and focus testing showed that most consumers preferred this format. Reception The PlayStation was mostly well received upon release. Critics in the west generally welcomed the new console; the staff of Next Generation reviewed the PlayStation a few weeks after its North American launch, where they commented that, while the CPU is "fairly average", the supplementary custom hardware, such as the GPU and sound processor, is stunningly powerful. They praised the PlayStation's focus on 3D, and complemented the comfort of its controller and the convenience of its memory cards. Giving the system 41⁄2 out of 5 stars, they concluded, "To succeed in this extremely cut-throat market, you need a combination of great hardware, great games, and great marketing. Whether by skill, luck, or just deep pockets, Sony has scored three out of three in the first salvo of this war." Albert Kim from Entertainment Weekly praised the PlayStation as a technological marvel, rivalling that of Sega and Nintendo. Famicom Tsūshin scored the console a 19 out of 40, lower than the Saturn's 24 out of 40, in May 1995. In a 1997 year-end review, a team of five Electronic Gaming Monthly editors gave the PlayStation scores of 9.5, 8.5, 9.0, 9.0, and 9.5—for all five editors, the highest score they gave to any of the five consoles reviewed in the issue. They lauded the breadth and quality of the games library, saying it had vastly improved over previous years due to developers mastering the system's capabilities in addition to Sony revising their stance on 2D and role playing games. They also complimented the low price point of the games compared to the Nintendo 64's, and noted that it was the only console on the market that could be relied upon to deliver a solid stream of games for the coming year, primarily due to third party developers almost unanimously favouring it over its competitors. Legacy SCE was an upstart in the video game industry in late 1994, as the video game market in the early 1990s was dominated by Nintendo and Sega. Nintendo had been the clear leader in the industry since the introduction of the Nintendo Entertainment System in 1985 and the Nintendo 64 was initially expected to maintain this position. The PlayStation's target audience included the generation which was the first to grow up with mainstream video games, along with 18- to 29-year-olds who were not the primary focus of Nintendo. By the late 1990s, Sony became a highly regarded console brand due to the PlayStation, with a significant lead over second-place Nintendo, while Sega was relegated to a distant third. The PlayStation became the first "computer entertainment platform" to ship over 100 million units worldwide, with many critics attributing the console's success to third-party developers. It remains the sixth best-selling console of all time as of 2025[update], with a total of 102.49 million units sold. Around 7,900 individual games were published for the console during its 11-year life span, the second-most games ever produced for a console. Its success resulted in a significant financial boon for Sony as profits from their video game division contributed to 23%. Sony's next-generation PlayStation 2, which is backward compatible with the PlayStation's DualShock controller and games, was announced in 1999 and launched in 2000. The PlayStation's lead in installed base and developer support paved the way for the success of its successor, which overcame the earlier launch of the Sega's Dreamcast and then fended off competition from Microsoft's newcomer Xbox and Nintendo's GameCube. The PlayStation 2's immense success and failure of the Dreamcast were among the main factors which led to Sega abandoning the console market. To date, five PlayStation home consoles have been released, which have continued the same numbering scheme, as well as two portable systems. The PlayStation 3 also maintained backward compatibility with original PlayStation discs. Hundreds of PlayStation games have been digitally re-released on the PlayStation Portable, PlayStation 3, PlayStation Vita, PlayStation 4, and PlayStation 5. The PlayStation has often ranked among the best video game consoles. In 2018, Retro Gamer named it the third best console, crediting its sophisticated 3D capabilities as one of its key factors in gaining mass success, and lauding it as a "game-changer in every sense possible". In 2009, IGN ranked the PlayStation the seventh best console in their list, noting its appeal towards older audiences to be a crucial factor in propelling the video game industry, as well as its assistance in transitioning game industry to use the CD-ROM format. Keith Stuart from The Guardian likewise named it as the seventh best console in 2020, declaring that its success was so profound it "ruled the 1990s". In January 2025, Lorentio Brodesco announced the nsOne project, attempting to reverse engineer PlayStation's motherboard. Brodesco stated that "detailed documentation on the original motherboard was either incomplete or entirely unavailable". The project was successfully crowdfunded via Kickstarter. In June, Brodesco manufactured the first working motherboard, promising to bring a fully rooted version with multilayer routing as well as documentation and design files in the near future. The success of the PlayStation contributed to the demise of cartridge-based home consoles. While not the first system to use an optical disc format, it was the first highly successful one, and ended up going head-to-head with the proprietary cartridge-relying Nintendo 64,[d] which the industry had expected to use CDs like PlayStation. After the demise of the Sega Saturn, Nintendo was left as Sony's main competitor in Western markets. Nintendo chose not to use CDs for the Nintendo 64; they were likely concerned with the proprietary cartridge format's ability to help enforce copy protection, given their substantial reliance on licensing and exclusive games for their revenue. Besides their larger capacity, CD-ROMs could be produced in bulk quantities at a much faster rate than ROM cartridges, a week compared to two to three months. Further, the cost of production per unit was far cheaper, allowing Sony to offer games about 40% lower cost to the user compared to ROM cartridges while still making the same amount of net revenue. In Japan, Sony published fewer copies of a wide variety of games for the PlayStation as a risk-limiting step, a model that had been used by Sony Music for CD audio discs. The production flexibility of CD-ROMs meant that Sony could produce larger volumes of popular games to get onto the market quickly, something that could not be done with cartridges due to their manufacturing lead time. The lower production costs of CD-ROMs also allowed publishers an additional source of profit: budget-priced reissues of games which had already recouped their development costs. Tokunaka remarked in 1996: Choosing CD-ROM is one of the most important decisions that we made. As I'm sure you understand, PlayStation could just as easily have worked with masked ROM [cartridges]. The 3D engine and everything—the whole PlayStation format—is independent of the media. But for various reasons (including the economies for the consumer, the ease of the manufacturing, inventory control for the trade, and also the software publishers) we deduced that CD-ROM would be the best media for PlayStation. The increasing complexity of developing games pushed cartridges to their storage limits and gradually discouraged some third-party developers. Part of the CD format's appeal to publishers was that they could be produced at a significantly lower cost and offered more production flexibility to meet demand. As a result, some third-party developers switched to the PlayStation, including Square and Enix, whose Final Fantasy VII and Dragon Quest VII respectively had been planned for the Nintendo 64 (both companies later merged to form Square Enix). Other developers released fewer games for the Nintendo 64 (Konami, releasing only thirteen N64 games but over fifty on the PlayStation). Nintendo 64 game releases were less frequent than the PlayStation's, with many being developed by either Nintendo themselves or second-parties such as Rare. The PlayStation Classic is a dedicated video game console made by Sony Interactive Entertainment that emulates PlayStation games. It was announced in September 2018 at the Tokyo Game Show, and released on 3 December 2018, the 24th anniversary of the release of the original console. As a dedicated console, the PlayStation Classic features 20 pre-installed games; the games run off the open source emulator PCSX. The console is bundled with two replica wired PlayStation controllers (those without analogue sticks), an HDMI cable, and a USB-Type A cable. Internally, the console uses a MediaTek MT8167a Quad A35 system on a chip with four central processing cores clocked at @ 1.5 GHz and a Power VR GE8300 graphics processing unit. It includes 16 GB of eMMC flash storage and 1 Gigabyte of DDR3 SDRAM. The PlayStation Classic is 45% smaller than the original console. The PlayStation Classic received negative reviews from critics and was compared unfavorably to Nintendo's rival Nintendo Entertainment System Classic Edition and Super Nintendo Entertainment System Classic Edition. Criticism was directed at its meagre game library, user interface, emulation quality, use of PAL versions for certain games, use of the original controller, and high retail price, though the console's design received praise. The console sold poorly. See also Notes References |

Contents The New York Times The New York Times (NYT)[b] is a newspaper based in Manhattan, New York City. The New York Times covers domestic, national, and international news, and publishes opinion pieces and reviews. As one of the longest-running newspapers in the United States, the Times serves as one of the country's newspapers of record. As of August 2025[update], The New York Times had 11.88 million total and 11.3 million online subscribers, both by significant margins the highest numbers for any newspaper in the United States; the total also included 580,000 print subscribers. The New York Times is published by the New York Times Company; since 1896, the company has been chaired by the Ochs-Sulzberger family, whose current chairman and the paper's publisher is A. G. Sulzberger. The Times is headquartered at The New York Times Building in Midtown Manhattan. The Times was founded as the conservative New-York Daily Times in 1851, and came to national recognition in the 1870s with its aggressive coverage of corrupt politician Boss Tweed. Following the Panic of 1893, Chattanooga Times publisher Adolph Ochs gained a controlling interest in the company. In 1935, Ochs was succeeded by his son-in-law, Arthur Hays Sulzberger, who began a push into European news. Sulzberger's son Arthur Ochs Sulzberger became publisher in 1963, adapting to a changing newspaper industry and introducing radical changes. The New York Times was involved in the landmark 1964 U.S. Supreme Court case New York Times Co. v. Sullivan, which restricted the ability of public officials to sue the media for defamation. In 1971, The New York Times published the Pentagon Papers, an internal Department of Defense document detailing the United States's historical involvement in the Vietnam War, despite pushback from then-president Richard Nixon. In the landmark decision New York Times Co. v. United States (1971), the Supreme Court ruled that the First Amendment guaranteed the right to publish the Pentagon Papers. In the 1980s, the Times began a two-decade progression to digital technology and launched nytimes.com in 1996. In the 21st century, it shifted its publication online amid the global decline of newspapers. Currently, the Times maintains several regional bureaus staffed with journalists across six continents. It has expanded to several other publications, including The New York Times Magazine, The New York Times International Edition, and The New York Times Book Review. In addition, the paper has produced several television series, podcasts—including The Daily—and games through The New York Times Games. The New York Times has been involved in a number of controversies in its history. Among other accolades, it has been awarded the Pulitzer Prize 135 times since 1918, the most of any publication. According to a 2025 Pew Research Center study on educational differences among audiences of 30 major U.S. news outlets, The New York Times had the highest proportion of college-educated readers among the daily newspapers surveyed, with 56% of its audience holding at least a bachelor's degree. History The New York Times was established in 1851 as the New-York Daily Times by New-York Tribune journalists Henry Jarvis Raymond and George Jones. The Times experienced significant circulation, particularly among conservatives; New-York Tribune publisher Horace Greeley praised the Times. During the American Civil War, Times correspondents gathered information directly from Confederate states. In 1869, Jones inherited the paper from Raymond, who had changed its name to The New-York Times. Under Jones, the Times began to publish a series of articles criticizing Tammany Hall political boss William M. Tweed, despite vehement opposition from other New York newspapers. In 1871, The New-York Times published Tammany Hall's accounting books; Tweed was tried in 1873 and sentenced to twelve years in prison. The Times earned national recognition for its coverage of Tweed. In 1891, Jones died, creating a management imbroglio in which his children had insufficient business acumen to inherit the company and his will prevented an acquisition of the Times. Editor-in-chief Charles Ransom Miller, editorial editor Edward Cary, and correspondent George F. Spinney established a company to manage The New-York Times, but faced financial difficulties during the Panic of 1893. In August 1896, Chattanooga Times publisher Adolph Ochs acquired The New-York Times, implementing significant alterations to the newspaper's structure. Ochs established the Times as a merchant's newspaper and removed the hyphen from the newspaper's name. In 1905, The New York Times opened Times Tower, marking expansion. The Times experienced a political realignment in the 1910s amid several disagreements within the Republican Party. The New York Times reported on the sinking of the Titanic, as other newspapers were cautious about bulletins circulated by the Associated Press. Through managing editor Carr Van Anda, the Times paid considerable attention to advances in science, reporting on Albert Einstein's then-obscure theory of general relativity and becoming involved in the discovery of the tomb of Tutankhamun. In April 1935, Ochs died, leaving his son-in-law Arthur Hays Sulzberger as publisher. The Great Depression forced Sulzberger to reduce The New York Times's operations, and developments in the New York newspaper landscape resulted in the formation of larger newspapers, such as the New York Herald Tribune and the New York World-Telegram. In contrast to Ochs, Sulzberger encouraged wirephotography. The New York Times extensively covered World War II through large headlines, reporting on exclusive stories such as the Yugoslav coup d'état. Amid the war, Sulzberger began expanding the Times's operations further, acquiring WQXR-FM in 1944—the first non-Times investment since the Jones era—and established a fashion show in Times Hall. Despite reductions as a result of conscription, The New York Times retained the largest journalism staff of any newspaper. The Times's print edition became available internationally during the war through the Army & Air Force Exchange Service; The New York Times Overseas Weekly later became available in Japan through The Asahi Shimbun and in Germany through the Frankfurter Zeitung. The international edition would develop into a separate newspaper. Journalist William L. Laurence publicized the atomic bomb race between the United States and Germany, resulting in the Federal Bureau of Investigation seizing copies of the Times. The United States government recruited Laurence to document the Manhattan Project in April 1945. Laurence became the only witness of the Manhattan Project, a detail realized by employees of The New York Times following the atomic bombing of Hiroshima. Following World War II, The New York Times continued to expand. The Times was subject to investigations from the Senate Internal Security Subcommittee, a McCarthyist subcommittee that investigated purported communism from within press institutions. Arthur Hays Sulzberger's decision to dismiss a copyreader who had pleaded the Fifth Amendment drew ire from within the Times and from external organizations. In April 1961, Sulzberger resigned, appointing his son-in-law, The New York Times Company president Orvil Dryfoos. Under Dryfoos, The New York Times established a newspaper based in Los Angeles. In 1962, the implementation of automated printing presses in response to increasing costs mounted fears over technological unemployment. The New York Typographical Union staged a strike in December, altering the media consumption of New Yorkers. The strike left New York with three remaining newspapers—the Times, the Daily News, and the New York Post—by its conclusion in March 1963. In May, Dryfoos died of a heart ailment. Following weeks of ambiguity, Arthur Ochs Sulzberger became The New York Times's publisher. Technological advancements leveraged by newspapers such as the Los Angeles Times and improvements in coverage from The Washington Post and The Wall Street Journal necessitated adaptations to nascent computing. The New York Times published "Heed Their Rising Voices" in 1960, a full-page advertisement purchased by supporters of Martin Luther King Jr. criticizing law enforcement in Montgomery, Alabama for their response to the civil rights movement. Montgomery Public Safety commissioner L. B. Sullivan sued the Times for defamation. In New York Times Co. v. Sullivan (1964), the U.S. Supreme Court ruled that the verdict in Alabama county court and the Supreme Court of Alabama violated the First Amendment. The decision is considered to be landmark. After financial losses, The New York Times ended its international edition, acquiring a stake in the Paris Herald Tribune, forming the International Herald Tribune. The Times initially published the Pentagon Papers, facing opposition from then-president Richard Nixon. The Supreme Court ruled in The New York Times's favor in New York Times Co. v. United States (1971), allowing the Times and The Washington Post to publish the papers. The New York Times remained cautious in its initial coverage of the Watergate scandal. As Congress began investigating the scandal, the Times furthered its coverage, publishing details on the Huston Plan, alleged wiretapping of reporters and officials, and testimony from James W. McCord Jr. that the Committee for the Re-Election of the President paid the conspirators off. The exodus of readers to suburban New York newspapers, such as Newsday and Gannett papers, adversely affected The New York Times's circulation. Contemporary newspapers balked at additional sections; Time devoted a cover for its criticism and New York wrote that the Times was engaging in "middle-class self-absorption". The New York Times, the Daily News, and the New York Post were the subject of a strike in 1978, allowing emerging newspapers to leverage halted coverage. The Times deliberately avoided coverage of the AIDS epidemic, running its first front-page article in May 1983. Max Frankel's editorial coverage of the epidemic, with mentions of anal intercourse, contrasted with then-executive editor A. M. Rosenthal's puritan approach, intentionally avoiding descriptions of the luridity of gay venues. Following years of waning interest in The New York Times, Sulzberger resigned in January 1992, appointing his son, Arthur Ochs Sulzberger Jr., as publisher. The Internet represented a generational shift within the Times; Sulzberger, who negotiated The New York Times Company's acquisition of The Boston Globe in 1993, derided the Internet, while his son expressed antithetical views. @times appeared on America Online's website in May 1994 as an extension of The New York Times, featuring news articles, film reviews, sports news, and business articles. Despite opposition, several employees of the Times had begun to access the Internet. The online success of publications that traditionally co-existed with the Times—such as America Online, Yahoo, and CNN—and the expansion of websites such as Monster.com and Craigslist that threatened The New York Times's classified advertisement model increased efforts to develop a website. nytimes.com debuted on January 19 and was formally announced three days later. The Times published domestic terrorist Ted Kaczynski's essay Industrial Society and Its Future in 1995, contributing to his arrest after his brother David recognized the essay's penmanship. Following the establishment of nytimes.com, The New York Times retained its journalistic hesitancy under executive editor Joseph Lelyveld, refusing to publish an article reporting on the Clinton–Lewinsky scandal from Drudge Report. nytimes.com editors conflicted with print editors on several occasions, including wrongfully naming security guard Richard Jewell as the suspect in the Centennial Olympic Park bombing and covering the death of Diana, Princess of Wales in greater detail than the print edition. The New York Times Electronic Media Company was adversely affected by the dot-com crash. The Times extensively covered the September 11 attacks. The following day's print issue contained sixty-six articles, the work of over three hundred dispatched reporters. Journalist Judith Miller was the recipient of a package containing a white powder during the 2001 anthrax attacks, furthering anxiety within The New York Times. In September 2002, Miller and military correspondent Michael R. Gordon wrote an article for the Times claiming that Iraq had purchased aluminum tubes. The article was cited by then-president George W. Bush to claim that Iraq was constructing weapons of mass destruction; the theoretical use of aluminum tubes to produce nuclear material was speculation. In March 2003, the United States invaded Iraq, beginning the Iraq War. The New York Times attracted controversy after thirty-six articles from journalist Jayson Blair were discovered to be plagiarized. Criticism over then-executive editor Howell Raines and then-managing editor Gerald M. Boyd mounted following the scandal, culminating in a town hall in which a deputy editor criticized Raines for failing to question Blair's sources in article he wrote on the D.C. sniper attacks. In June 2003, Raines and Boyd resigned. Arthur Ochs Sulzberger Jr. appointed Bill Keller as executive editor. Miller continued to report on the Iraq War as a journalistic embed covering the country's weapons of mass destruction program. Keller and then-Washington bureau chief Jill Abramson unsuccessfully attempted to subside criticism. Conservative media criticized the Times over its coverage of missing explosives from the Al Qa'qaa weapons facility. An article in December 2005 disclosing warrantless surveillance by the National Security Agency contributed to further criticism from the George W. Bush administration and the Senate's refusal to renew the Patriot Act. In the Plame affair, a Central Intelligence Agency inquiry found that Miller had become aware of Valerie Plame's identity through then-vice president Dick Cheney's chief of staff Scooter Libby, resulting in Miller's resignation. During the Great Recession, The New York Times suffered significant fiscal difficulties as a consequence of the subprime mortgage crisis and a decline in classified advertising. Exacerbated by Rupert Murdoch's revitalization of The Wall Street Journal through his acquisition of Dow Jones & Company, The New York Times Company began enacting measures to reduce the newsroom budget. The company was forced to borrow $250 million (equivalent to $373.84 million in 2025) from Mexican billionaire Carlos Slim and fired over one hundred employees by 2010. nytimes.com's coverage of the Eliot Spitzer prostitution scandal, resulting in the resignation of then-New York governor Eliot Spitzer, furthered the legitimacy of the website as a journalistic medium. The Times's economic downturn renewed discussions of an online paywall; The New York Times implemented a paywall in March 2011. Abramson succeeded Keller, continuing her characteristic investigations into corporate and government malfeasance into the Times's coverage. Following conflicts with newly appointed chief executive Mark Thompson's ambitions, Abramson was dismissed by Sulzberger Jr., who named Dean Baquet as her replacement. Leading up to the 2016 presidential election, The New York Times elevated the Hillary Clinton email controversy into a national issue. Donald Trump's upset victory contributed to an increase in subscriptions to the Times. The New York Times experienced unprecedented indignation from Trump, who referred to publications such as the Times as "enemies of the people" at the Conservative Political Action Conference and tweeted his disdain for the newspaper and CNN. In October 2017, The New York Times published an article by journalists Jodi Kantor and Megan Twohey alleging that dozens of women had accused film producer and The Weinstein Company co-chairman Harvey Weinstein of sexual misconduct. The investigation resulted in Weinstein's resignation and conviction, precipitated the Weinstein effect, and served as a catalyst for the #MeToo movement. The New York Times Company vacated the public editor position and eliminated the copy desk in November. Sulzberger Jr. announced his resignation in December 2017, appointing his son, A. G. Sulzberger, as publisher. Trump's relationship—equally diplomatic and negative—marked Sulzberger's tenure. In September 2018, The New York Times published "I Am Part of the Resistance Inside the Trump Administration", an anonymous essay by a self-described Trump administration official later revealed to be Department of Homeland Security chief of staff Miles Taylor. The animosity—which extended to nearly three hundred instances of Trump disparaging the Times by May 2019—culminated in Trump ordering federal agencies to cancel their subscriptions to The New York Times and The Washington Post in October 2019. Trump's tax returns have been the subject of three separate investigations.[c] During the COVID-19 pandemic, the Times began implementing data services and graphs. On May 23, 2020, The New York Times's front page solely featured U.S. Deaths Near 100,000, An Incalculable Loss, a subset of the 100,000 people in the United States who died of COVID-19, the first time that the Times's front page lacked images since they were introduced. Since 2020, The New York Times has focused on broader diversification, developing online games and producing television series. The New York Times Company acquired The Athletic in January 2022. Organization Since 1896, The New York Times has been published by the Ochs-Sulzberger family, having previously been published by Henry Jarvis Raymond until 1869 and by George Jones until 1896. Adolph Ochs published the Times until his death in 1935, when he was succeeded by his son-in-law, Arthur Hays Sulzberger. Sulzberger was publisher until 1961 and was succeeded by Orvil Dryfoos, his son-in-law, who served in the position until his death in 1963. Arthur Ochs Sulzberger succeeded Dryfoos until his resignation in 1992. His son, Arthur Ochs Sulzberger Jr., served as publisher until 2018. The New York Times's current publisher is A. G. Sulzberger, Sulzberger Jr.'s son. As of 2023, the Times's executive editor is Joseph Kahn and the paper's managing editors are Marc Lacey and Carolyn Ryan, having been appointed in June 2022. The New York Times's deputy managing editors are Sam Dolnick, Monica Drake, and Steve Duenes, and the paper's assistant managing editors are Matthew Ericson, Jonathan Galinsky, Hannah Poferl, Sam Sifton, Karron Skog, and Michael Slackman. The New York Times is owned by The New York Times Company, a publicly traded company. The New York Times Company, in addition to the Times, owns Wirecutter, The Athletic, The New York Times Cooking, and The New York Times Games, and acquired Serial Productions and Audm. The New York Times Company holds undisclosed minority investments in multiple other businesses, and formerly owned The Boston Globe and several radio and television stations. The New York Times Company is majority-owned by the Ochs-Sulzberger family through elevated shares in the company's dual-class stock structure held largely in a trust, in effect since the 1950s; as of 2022, the family holds ninety-five percent of The New York Times Company's Class B shares, allowing it to elect seventy percent of the company's board of directors. Class A shareholders have restrictive voting rights. As of 2023, The New York Times Company's chief executive is Meredith Kopit Levien, the company's former chief operating officer who was appointed in September 2020. As of March 2023, The New York Times Company employs 5,800 individuals, including 1,700 journalists according to deputy managing editor Sam Dolnick. Journalists for The New York Times may not run for public office, provide financial support to political candidates or causes, endorse candidates, or demonstrate public support for causes or movements. Journalists are subject to the guidelines established in "Ethical Journalism" and "Guidelines on Integrity". According to the former, Times journalists must abstain from using sources with a personal relationship to them and must not accept reimbursements or inducements from individuals who may be written about in The New York Times, with exceptions for gifts of nominal value. The latter requires attribution and exact quotations, though exceptions are made for linguistic anomalies. Staff writers are expected to ensure the veracity of all written claims, but may delegate researching obscure facts to the research desk. In March 2021, the Times established a committee to avoid journalistic conflicts of interest with work written for The New York Times, following columnist David Brooks's resignation from the Aspen Institute for his undisclosed work on the initiative Weave. The New York Times editorial board was established in 1896 by Adolph Ochs. With the opinion department, the editorial board is independent of the newsroom. Then-editor-in-chief Charles Ransom Miller served as opinion editor from 1883 until his death in 1922. Rollo Ogden succeeded Miller until his death in 1937. From 1937 to 1938, John Huston Finley served as opinion editor; in a prearranged plan, Charles Merz succeeded Finley. Merz served in the position until his retirement in 1961. John Bertram Oakes served as opinion editor from 1961 to 1976, when then-publisher Arthur Ochs Sulzberger appointed Max Frankel. Frankel served in the position until 1986, when he was appointed as executive editor. Jack Rosenthal was the opinion editor from 1986 to 1993. Howell Raines succeeded Rosenthal until 2001, when he was made executive editor. Gail Collins succeeded Raines until her resignation in 2006. From 2007 to 2016, Andrew Rosenthal was the opinion editor. James Bennet succeeded Rosenthal until his resignation in 2020. As of July 2024[update], the editorial board comprises thirteen opinion writers. The New York Times's opinion editor is Kathleen Kingsbury and the deputy opinion editor is Patrick Healy. The New York Times's editorial board was initially opposed to liberal beliefs, opposing women's suffrage in 1900 and 1914. The editorial board began to espouse progressive beliefs during Oakes's tenure, conflicting with the Ochs-Sulzberger family, of which Oakes was a member as Adolph Ochs's nephew; in 1976, Oakes publicly disagreed with Sulzberger's endorsement of Daniel Patrick Moynihan over Bella Abzug in the 1976 Senate Democratic primaries in a letter sent from Martha's Vineyard. Under Rosenthal, the editorial board took positions supporting assault weapons legislation and the legalization of marijuana, but publicly criticized the Obama administration over its portrayal of terrorism. In presidential elections, The New York Times has endorsed a total of twelve Republican candidates and thirty-two Democratic candidates, and has endorsed the Democrat in every election since 1960.[j] With the exception of Wendell Willkie, Republicans endorsed by the Times have won the presidency. In 2016, the editorial board issued an anti-endorsement against Donald Trump for the first time in its history. In February 2020, the editorial board reduced its presence from several editorials each day to occasional editorials for events deemed particularly significant. Since August 2024, the board no longer endorses candidates in local or congressional races in New York. Since 1940, editorial, media, and technology workers of The New York Times have been represented by the New York Times Guild. The Times Guild, along with the Times Tech Guild, are represented by the NewsGuild-CWA. In 1940, Arthur Hays Sulzberger was called upon by the National Labor Relations Board amid accusations that he had discouraged Guild membership in the Times. Over the next few years, the Guild would ratify several contracts, expanding to editorial and news staff in 1942 and maintenance workers in 1943. The New York Times Guild has walked out several times in its history, including for six and a half hours in 1981 and in 2017, when copy editors and reporters walked out at lunchtime in response to the elimination of the copy desk. On December 7, 2022, the union held a one-day strike, the first interruption to The New York Times since 1978. The New York Times Guild reached an agreement in May 2023 to increase minimum salaries for employees and a retroactive bonus. The Times Tech Guild is the largest technology union with collective bargaining rights in the United States. The guild held a second strike beginning on November 4, 2024, threatening the Times's coverage of the 2024 United States presidential election. Content As of August 2025, The New York Times has 11.8 million subscribers, with 11.3 million online-only subscribers and 580,000 print subscribers. The New York Times Company intends to have 15 million subscribers by 2027. The Times's shift towards subscription-based revenue with the debut of an online paywall in 2011 contributed to subscription revenue exceeding advertising revenue the following year, furthered by the 2016 presidential election and Donald Trump. In 2022, Vox wrote that The New York Times's subscribers skew "older, richer, whiter, and more liberal"; to reflect the general population of the United States, the Times has attempted to alter its audience by acquiring The Athletic, investing in verticals such as The New York Times Games, and beginning a marketing campaign showing diverse subscribers to the Times. The New York Times Company chief executive Meredith Kopit Levien stated that the average age of subscribers has remained constant. In October 2001, The New York Times began publishing DealBook, a financial newsletter edited by Andrew Ross Sorkin. The Times had intended to publish the newsletter in September, but delayed its debut following the September 11 attacks. A website for DealBook was established in March 2006. The New York Times began shifting towards DealBook as part of the newspaper's financial coverage in November 2010 with a renewed website and a presence in the Times's print edition. In 2011, the Times began hosting the DealBook Summit, an annual conference hosted by Sorkin. During the COVID-19 pandemic, The New York Times hosted the DealBook Online Summit in 2020 and 2021. The 2022 DealBook Summit featured—among other speakers—former vice president Mike Pence and Israeli prime minister Benjamin Netanyahu, culminating in an interview with former FTX chief executive Sam Bankman-Fried; FTX had filed for bankruptcy several weeks prior. The 2023 DealBook Summit's speakers included vice president Kamala Harris, Israeli president Isaac Herzog, and businessman Elon Musk. In June 2010, The New York Times licensed the political blog FiveThirtyEight in a three-year agreement. The blog, written by Nate Silver, had garnered attention during the 2008 presidential election for predicting the elections in forty-nine of fifty states. FiveThirtyEight appeared on nytimes.com in August. According to Silver, several offers were made for the blog; Silver wrote that a merger of unequals must allow for editorial sovereignty and resources from the acquirer, comparing himself to Groucho Marx. According to The New Republic, FiveThirtyEight drew as much as a fifth of the traffic to nytimes.com during the 2012 presidential election. In July 2013, FiveThirtyEight was sold to ESPN. In an article following Silver's exit, public editor Margaret Sullivan wrote that he was disruptive to the Times's culture for his perspective on probability-based predictions and scorn for polling—having stated that punditry is "fundamentally useless", comparing him to Billy Beane, who implemented sabermetrics in baseball. According to Sullivan, his work was criticized by several notable political journalists. The New Republic obtained a memo in November 2013 revealing then-Washington bureau chief David Leonhardt's ambitions to establish a data-driven newsletter with presidential historian Michael Beschloss, graphic designer Amanda Cox, economist Justin Wolfers, and The New Republic journalist Nate Cohn. By March, Leonhardt had amassed fifteen employees from within The New York Times; the newsletter's staff included individuals who had created the Times's dialect quiz, fourth down analyzer, and a calculator for determining buying or renting a home. The Upshot debuted in April 2014. Fast Company reviewed an article about Illinois Secure Choice—a state-funded retirement saving system—as "neither a terse news item, nor a formal financial advice column, nor a politically charged response to economic policy", citing its informal and neutral tone. The Upshot developed "the needle" for the 2016 presidential election and 2020 presidential elections, a thermometer dial displaying the probability of a candidate winning. In January 2016, Cox was named editor of The Upshot. Kevin Quealy was named editor in June 2022. The New York Times has said it is perceived as a liberal newspaper. An analysis by Pew Research Center in October 2014 placed the Times readership as ideologically liberal based on a scale of 10 political values questions. According to an internal readership poll conducted by The New York Times in 2019, eighty-four percent of readers identified as liberal. The New York Times has struggled internally with how to balance its coverage, dismissing criticism from the left for "sanewashing" right-wing viewpoints in its coverage of Donald Trump. In covering Israel's war on the Gaza Strip that began in 2023, The New York Times instructed its reporters to restrict use of the terms 'Palestine', 'genocide', and 'refugee camps' to specific usages, with data analysis showing a pattern of articles emphasizing Israeli civilians killed by Palestinians over a much larger number of Palestinian civilians killed by Israelis. The group Writers Against the War on Gaza wrote in the blog Mondoweiss that this has contrasted with The New York Times coverage of Russia's invasion of Ukraine, in which Russia is considered a threat to U.S. foreign policy interests, while Israel is considered an ally. In February 1942, The New York Times crossword debuted in The New York Times Magazine; according to Richard Shepard, the attack on Pearl Harbor in December 1941 convinced then-publisher Arthur Hays Sulzberger of the necessity of a crossword. The New York Times has published recipes since the 1850s and has had a separate food section since the 1940s. In 1961, restaurant critic Craig Claiborne published The New York Times Cookbook, an unauthorized cookbook that drew from the Times's recipes. Since 2010, former food editor Amanda Hesser has published The Essential New York Times Cookbook, a compendium of recipes from The New York Times. The Innovation Report in 2014 revealed that the Times had attempted to establish a cooking website since 1998, but faced difficulties with the absence of a defined data structure. In September 2014, The New York Times introduced NYT Cooking, an application and website. Edited by food editor Sam Sifton, the Times's cooking website features 21,000 recipes as of 2022. NYT Cooking features videos as part of an effort by Sifton to hire two former Tasty employees from BuzzFeed. In August 2023, NYT Cooking added personalized recommendations through the cosine similarity of text embeddings of recipe titles. The website also features no-recipe recipes, a concept proposed by Sifton. In May 2016, The New York Times Company announced a partnership with startup Chef'd to form a meal delivery service that would deliver ingredients from The New York Times Cooking recipes to subscribers; Chef'd shut down in July 2018 after failing to accrue capital and secure financing. The Hollywood Reporter reported in September 2022 that the Times would expand its delivery options to US$95 cooking kits curated by chefs such as Nina Compton, Chintan Pandya, and Naoko Takei Moore. That month, the staff of NYT Cooking went on tour with Compton, Pandya, and Moore in Los Angeles, New Orleans, and New York City, culminating in a food festival. In addition, The New York Times offered its own wine club originally operated by the Global Wine Company. The New York Times Wine Club was established in August 2009, during a dramatic decrease in advertising revenue. By 2021, the wine club was managed by Lot18, a company that provides proprietary labels. Lot18 managed the Williams Sonoma Wine Club and its own wine club Tasting Room. The New York Times archives its articles in a basement annex beneath its building known as "the morgue", a venture started by managing editor Carr Van Anda in 1907. The morgue comprises news clippings, a pictures library, and the Times's book and periodicals library. As of 2014, it is the largest library of any media company, dating back to 1851. In November 2018, The New York Times partnered with Google to digitize the Archival Library. Additionally, The New York Times has maintained a virtual microfilm reader known as TimesMachine since 2014. The service launched with archives from 1851 to 1980; in 2016, TimesMachine expanded to include archives from 1981 to 2002. The Times built a pipeline to take in TIFF images, article metadata in XML and an INI file of Cartesian geometry describing the boundaries of the page, and convert it into a PNG of image tiles and JSON containing the information in the XML and INI files. The image tiles are generated using GDAL and displayed using Leaflet, using data from a content delivery network. The Times ran optical character recognition on the articles using Tesseract and shingled and fuzzy string matched the result. The New York Times uses a proprietary content management system known as Scoop for its online content and the Microsoft Word-based content management system CCI for its print content. Scoop was developed in 2008 to serve as a secondary content management system for editors working in CCI to publish their content on the Times's website; as part of The New York Times's online endeavors, editors now write their content in Scoop and send their work to CCI for print publication. Since its introduction, Scoop has superseded several processes within the Times, including print edition planning and collaboration, and features tools such as multimedia integration, notifications, content tagging, and drafts. The New York Times uses private articles for high-profile opinion pieces, such as those written by Russian president Vladimir Putin and actress Angelina Jolie, and for high-level investigations. In January 2012, the Times released Integrated Content Editor (ICE), a revision tracking tool for WordPress and TinyMCE. ICE is integrated within the Times's workflow by providing a unified text editor for print and online editors, reducing the divide between print and online operations. By 2017, The New York Times began developing a new authoring tool to its content management system known as Oak, in an attempt to further the Times's visual efforts in articles and reduce the discrepancy between the mediums in print and online articles. The system reduces the input of editors and supports additional visual mediums in an editor that resembles the appearance of the article. Oak is based on ProseMirror, a JavaScript rich-text editor toolkit, and retains the revision tracking and commenting functionalities of The New York Times's previous systems. Additionally, Oak supports predefined article headers. In 2019, Oak was updated to support collaborative editing using Firebase to update editors's cursor status. Several Google Cloud Functions and Google Cloud Tasks allow articles to be previewed as they will be printed, and the Times's primary MySQL database is regularly updated to update editors on the article status. Style and design Since 1895, The New York Times has maintained a manual of style in several forms. The New York Times Manual of Style and Usage was published on the Times's intranet in 1999. The New York Times uses honorifics when referring to individuals. With the AP Stylebook's removal of honorifics in 2000 and The Wall Street Journal's omission of courtesy titles in May 2023, the Times is the only national newspaper that continues to use honorifics. According to former copy editor Merrill Perlman, The New York Times continues to use honorifics as a "sign of civility". The Times's use of courtesy titles led to an apocryphal rumor that the paper had referred to singer Meat Loaf as "Mr. Loaf". Several exceptions have been made; the former sports section and The New York Times Book Review do not use honorifics. A leaked memo following the killing of Osama bin Laden in May 2011 revealed that editors were given a last-minute instruction to omit the honorific from Osama bin Laden's name, consistent with deceased figures of historic significance, such as Adolf Hitler, Napoleon, and Vladimir Lenin. The New York Times uses academic and military titles for individuals prominently serving in that position. In 1986, the Times began to use Ms., and introduced the gender-neutral title Mx. in 2015. The New York Times uses initials when a subject has expressed a preference, such as Donald Trump. The New York Times maintains a strict but not absolute obscenity policy, including phrases. In a review of the Canadian hardcore punk band Fucked Up, music critic Kelefa Sanneh wrote that the band's name—entirely rendered in asterisks—would not be printed in the Times "unless an American president, or someone similar, says it by mistake"; The New York Times did not repeat then-vice president Dick Cheney's use of "fuck" against then-senator Patrick Leahy in 2004 or then-vice president Joe Biden's remarks that the passage of the Affordable Care Act in 2010 was a "big fucking deal". The Times's profanity policy has been tested by former president Donald Trump. The New York Times published Trump's Access Hollywood tape in October 2016, containing the words "fuck", "pussy", "bitch", and "tits", the first time the publication had published an expletive on its front page, and repeated an explicit phrase for fellatio stated by then-White House communications director Anthony Scaramucci in July 2017. The New York Times omitted Trump's use of the phrase "shithole countries" from its headline in favor of "vulgar language" in January 2018. The Times banned certain words, such as "bitch", "whore", and "sluts", from Wordle in 2022. Journalists for The New York Times do not write their own headlines, but rather copy editors who specifically write headlines. The Times's guidelines insist headline editors get to the main point of an article but avoid giving away endings, if present. Other guidelines include using slang "sparingly", avoiding tabloid headlines, not ending a line on a preposition, article, or adjective, and chiefly, not to pun. The New York Times Manual of Style and Usage states that wordplay, such as "Rubber Industry Bounces Back", is to be tested on a colleague as a canary is to be tested in a coal mine; "when no song bursts forth, start rewriting". The New York Times has amended headlines due to controversy. In 2019, following two back-to-back mass shootings in El Paso and Dayton, the Times used the headline, "Trump Urges Unity vs. Racism", to describe then-president Donald Trump's words after the shootings. After criticism from FiveThirtyEight founder Nate Silver, the headline was changed to, "Assailing Hate But Not Guns". Online, The New York Times's headlines do not face the same length restrictions as headlines that appear in print; print headlines must fit within a column, often six words. Additionally, headlines must "break" properly, containing a complete thought on each line without splitting up prepositions and adverbs. Writers may edit a headline to fit an article more aptly if further developments occur. The Times uses A/B testing for articles on the front page, placing two headlines against each other. At the end of the test, the headlines that receives more traffic is chosen. The alteration of a headline regarding intercepted Russian data used in the Mueller special counsel investigation was noted by Trump in a March 2017 interview with Time, in which he claimed that the headline used the word "wiretapped" in the print version of the paper on January 20, while the digital article on January 19 omitted the word. The headline was intentionally changed in the print version to use "wiretapped" in order to fit within the print guidelines. The nameplate of The New York Times has been unaltered since 1967. In creating the initial nameplate, Henry Jarvis Raymond took as his model the British newspaper The Times, which used a Blackletter style called Textura, popularized following the fall of the Western Roman Empire and regional variations of Alcuin's script, as well as a period. With the change to The New-York Times on September 14, 1857, the nameplate followed. Under George Jones, the terminals of the "N", "r", and "s" were intentionally exaggerated into swashes. The nameplate in the January 15, 1894, issue trimmed the terminals once more, smoothed the edges, and turned the stem supporting the "T" into an ornament. The hyphen was dropped on December 1, 1896, after Adolph Ochs purchased the paper. The descender of the "h" was shortened on December 30, 1914. The largest change to the nameplate was introduced on February 21, 1967, when type designer Ed Benguiat redesigned the logo, most prominently turning the arrow ornament into a diamond. Notoriously, the new logo dropped the period that had followed the word Times up until that point; one reader compared the omission of the period to "performing plastic surgery on Helen of Troy." Picture editor John Radosta worked with a New York University professor to determine that dropping the period saved the paper US$41.28 (equivalent to $398.59 in 2025). Print edition As of December 2023, The New York Times has printed sixty thousand issues, a statistic represented in the paper's masthead to the right of the volume number, the Times's years in publication written in Roman numerals. The volume and issues are separated by four dots representing the edition number of that issue; on the day of the 2000 presidential election, the Times was revised four separate times, necessitating the use of an em dash in place of an ellipsis. The em dash issue was printed hundreds times over before being replaced by the one-dot issue. Despite efforts by newsroom employees to recycle copies sent to The New York Times's office, several copies were kept, including one put on display at the Museum at The Times. From February 7, 1898, to December 31, 1999, the Times's issue number was incorrect by five hundred issues, an error suspected by The Atlantic to be the result of a careless front page type editor. The misreporting was noticed by news editor Aaron Donovan, who was calculating the number of issues in a spreadsheet and noticed the discrepancy. The New York Times celebrated fifty thousand issues on March 14, 1995, an observance that should have occurred on July 26, 1996. The New York Times has reduced the physical size of its print edition while retaining its broadsheet format. The New-York Daily Times debuted at 18 inches (460 mm) across. By the 1950s, the Times was being printed at 16 inches (410 mm) across. In 1953, an increase in paper costs to US$10 (equivalent to $120.34 in 2025) a ton increased newsprint costs to US$21.7 million (equivalent to $326,110,074.63 in 2025) On December 28, 1953, the pages were reduced to 15.5 inches (390 mm). On February 14, 1955, a further reduction to 15 inches (380 mm) occurred, followed by 14.5 and 13.5 inches (370 and 340 mm). On August 6, 2007, the largest cut occurred when the pages were reduced to 12 inches (300 mm),[k] a decision that other broadsheets had previously considered. Then-executive editor Bill Keller stated that a narrower paper would be more beneficial to the reader but acknowledged a net loss in article space of five percent. In 1985, The New York Times Company established a minority stake in a US$21.7 million (equivalent to $326,110,074.63 in 2025) newsprint plant in Clermont, Quebec through Donahue Malbaie. The company sold its equity interest in Donahue Malbaie in 2017. The New York Times often uses large, bolded headlines for major events. For the print version of the Times, these headlines are written by one copy editor, reviewed by two other copy editors, approved by the masthead editors, and polished by other print editors. The process is completed before 8 p.m., but it may be repeated if further development occur, as did take place during the 2020 presidential election. On the day Joe Biden was declared the winner, The New York Times utilized a "hammer headline" reading, "Biden Beats Trump", in all caps and bolded. A dozen journalists discussed several potential headlines, such as "It's Biden" or "Biden's Moment", and prepared for a Donald Trump victory, in which they would use "Trump Prevails". During Trump's first impeachment, the Times drafted the hammer headline, "Trump Impeached". The New York Times altered the ligatures between the E and the A, as not doing so would leave a noticeable gap due to the stem of the A sloping away from the E. The Times reused the tight kerning for "Biden Beats Trump" and Trump's second impeachment, which simply read, "Impeached". In cases where two major events occur on the same day or immediately after each other, The New York Times has used a "paddle wheel" headline, where both headlines are used but split by a line. The term dates back to August 8, 1959, when it was revealed that the United States was monitoring Soviet missile firings and when Explorer 6—shaped like a paddle wheel—launched. Since then, the paddle wheel has been used several times, including on January 21, 1981, when Ronald Reagan was sworn in minutes before Iran released fifty-two American hostages, ending the Iran hostage crisis. At the time, most newspapers favored the end of the hostage crisis, but the Times placed the inauguration above the crisis. Other occasions in which the paddle wheel has been used include on July 26, 2000, when the 2000 Camp David Summit ended without an agreement and when Bush announced that Dick Cheney would be his running mate, and on June 24, 2016, when the United Kingdom European Union membership referendum passed, beginning Brexit, and when the Supreme Court deadlocked in United States v. Texas. The New York Times has run editorials from its editorial board on the front page twice. On June 13, 1920, the Times ran an editorial opposing Warren G. Harding, who was nominated during that year's Republican Party presidential primaries. Amid growing acceptance to run editorials on the front pages from publications such as the Detroit Free Press, The Patriot-News, The Arizona Republic, and The Indianapolis Star, The New York Times ran an editorial on its front page on December 5, 2015, following a terrorist attack in San Bernardino, California, in which fourteen people were killed. The editorial advocates for the prohibition of "slightly modified combat rifles" used in the San Bernardino shooting and "certain kinds of ammunition". Conservative figures, including Texas senator Ted Cruz, The Weekly Standard editor Bill Kristol, Fox & Friends co-anchor Steve Doocy, and then-New Jersey governor Chris Christie criticized the Times. Talk radio host Erick Erickson acquired an issue of The New York Times to fire several rounds into the paper, posting a picture online. Since 1997, The New York Times's primary distribution center is located in College Point, Queens. The facility is 300,000 ft2 (28,000 m2) and employs 170 people as of 2017. The College Point distribution center prints 300,000 to 800,000 newspapers daily. On most occasions, presses start before 11 p.m. and finish before 3 a.m. A robotic crane grabs a roll of newsprint and several rollers ensure ink can be printed on paper. The final newspapers are wrapped in plastic and shipped out. As of 2018, the College Point facility accounted for 41 percent of production. Other copies are printed at 26 other publications, such as The Atlanta Journal-Constitution, The Dallas Morning News, The Santa Fe New Mexican, and the Courier Journal. With the decline of newspapers, particularly regional publications, the Times must travel further; for example, newspapers for Hawaii are flown from San Francisco on United Airlines, and Sunday papers are flown from Los Angeles on Hawaiian Airlines. Computer glitches, mechanical issues, and weather phenomena affect circulation but do not stop the paper from reaching customers. The College Point facility prints over two dozen other papers, including The Wall Street Journal and USA Today. The New York Times has halted its printing process several times to account for major developments. The first printing stoppage occurred on March 31, 1968, when then-president Lyndon B. Johnson announced that he would not seek a second term. Other press stoppages include May 19, 1994, for the death of former first lady Jacqueline Kennedy Onassis, and July 17, 1996, for Trans World Airlines Flight 800. The 2000 presidential election necessitated two press stoppages. Al Gore appeared to concede on November 8, forcing then-executive editor Joseph Lelyveld to stop the Times's presses to print a new headline, "Bush Appears to Defeat Gore", with a story that stated George W. Bush was elected president. However, Gore held off his concession speech over doubts over Florida. Lelyveld reran the headline, "Bush and Gore Vie for an Edge". Since 2000, three printing stoppages have been issued for the death of William Rehnquist on September 3, 2005, for the killing of Osama bin Laden on May 1, 2011, and for the passage of the Marriage Equality Act in the New York State Assembly and subsequent signage by then-governor Andrew Cuomo on June 24, 2011. Online platforms The New York Times website is hosted at nytimes.com. It has undergone several major redesigns and infrastructure developments since its debut. In April 2006, The New York Times redesigned its website with an emphasis on multimedia. In preparation for Super Tuesday in February 2008, the Times developed a live election system using the Associated Press's File Transfer Protocol (FTP) service and a Ruby on Rails application; nytimes.com experienced its largest traffic on Super Tuesday and the day after. The NYTimes application debuted with the introduction of the App Store on July 10, 2008. Engadget's Scott McNulty wrote critically of the app, negatively comparing it to The New York Times's mobile website. An iPad version with select articles was released on April 3, 2010, with the release of the first-generation iPad. In October, The New York Times expanded NYT Editors' Choice to include the paper's full articles. NYT for iPad was free until 2011. The Times applications on iPhone and iPad began offering in-app subscriptions in July 2011. The Times released a web application for iPad—featuring a format summarizing trending headlines on Twitter—and a Windows 8 application in October 2012. Efforts to ensure profitability through an online magazine and a "Need to Know" subscription emerged in Adweek in July 2013. In March 2014, The New York Times announced three applications—NYT Now, an application that offers pertinent news in a blog format, and two unnamed applications, later known as NYT Opinion and NYT Cooking—to diversify its product laterals. The Daily is the modern front page of The New York Times. The New York Times manages several podcasts, including multiple podcasts with Serial Productions. The Times's longest-running podcast is The Book Review Podcast, debuting as Inside The New York Times Book Review in April 2006. The New York Times's defining podcast is The Daily, a daily news podcast hosted by Michael Barbaro which debuted on February 1, 2017. Between March 2022 and March 2025, the approximately 30 minute programme was co-hosted with Sabrina Tavernise. Beginning in April 2025 Barbaro was joined by two new regular co-hosts, Natalie Kitroeff and Rachel Abrams. The Interview was launched in 2024 and is hosted weekly by David Marchese and Lulu Garcia-Navarro. Episodes typically last 40 to 50 minutes. Condensed versions of the interviews are published simultaneously in The New York Times Magazine. Guests have included politicians, actors, influential experts, media figures and high-profile writers. In October 2021, The New York Times began testing "New York Times Audio", an application featuring podcasts from the Times, audio versions of articles—including from other publications through Audm, and archives from This American Life. The application debuted in May 2023 exclusively on iOS for Times subscribers. New York Times Audio includes exclusive podcasts such as The Headlines, a daily news recap, and Shorts, short audio stories under ten minutes. In addition, a "Reporter Reads" section features Times journalists reading their articles and providing commentary. The New York Times has used video games as part of its journalistic efforts, among the first publications to do so, contributing to an increase in Internet traffic; the publication has also developed its own video games. In 2014, The New York Times Magazine introduced Spelling Bee, a word game in which players guess words from a set of letters in a honeycomb and are awarded points for the length of the word and receive extra points if the word is a pangram. The game was proposed by Will Shortz, created by Frank Longo, and has been maintained by Sam Ezersky. In May 2018, Spelling Bee was published on nytimes.com, furthering its popularity. In February 2019, the Times introduced Letter Boxed, in which players form words from letters placed on the edges of a square box, followed in June 2019 by Tiles, a matching game in which players form sequences of tile pairings, and Vertex, in which players connect vertices to assemble an image. In July 2023, The New York Times introduced Connections, in which players identify groups of words that are connected by a common property. In April, the Times introduced Digits, a game that required using operations on different values to reach a set number; Digits was shut down in August. In March 2024, The New York Times released Strands, a themed word search. In January 2022, The New York Times Company acquired Wordle, a word game developed by Josh Wardle in 2021, at a valuation in the "low-seven figures". The acquisition was proposed by David Perpich, a member of the Sulzberger family who proposed the purchase to Knight over Slack after reading about the game. The Washington Post purportedly considered acquiring Wordle, according to Vanity Fair. At the 2022 Game Developers Conference, Wardle stated that he was overwhelmed by the volume of Wordle facsimiles and overzealous monetization practices in other games. Concerns over The New York Times monetizing Wordle by implementing a paywall mounted; Wordle is a client-side browser game and can be played offline by downloading its webpage. Wordle moved to the Times's servers and website in February. The game was added to the NYT Games application in August, necessitating it be rewritten in the JavaScript library React. In November, The New York Times announced that Tracy Bennett would be the Wordle's editor. Other publications The New York Times Magazine and The Boston Globe Magazine are the only weekly Sunday magazines following The Washington Post Magazine's cancellation in December 2022. In February 2016, The New York Times introduced a Spanish website, The New York Times en Español. The website, intended to be read on mobile devices, would contain translated articles from the Times and reporting from journalists based in Mexico City. The Times en Español's style editor is Paulina Chavira, who has advocated for pluralistic Spanish to accommodate the variety of nationalities in the newsroom's journalists and wrote a stylebook for The New York Times en Español. Articles the Times intends to publish in Spanish are sent to a translation agency and adapted for Spanish writing conventions; the present progressive tense may be used for forthcoming events in English, but other tenses are preferable in Spanish. The Times en Español consults the Real Academia Española and Fundéu and frequently modifies the use of diacritics—such as using an acute accent for the Cártel de Sinaloa but not the Cartel de Medellín—and using the gender-neutral pronoun elle. Headlines in The New York Times en Español are not capitalized. The Times en Español publishes El Times, a newsletter led by Elda Cantú intended for all Spanish speakers. In September 2019, The New York Times ended The New York Times en Español's separate operations. A study published in The Translator in 2023 found that the Times en Español engaged in tabloidization. In June 2012, The New York Times introduced a Chinese website, 纽约时报中文, in response to Chinese editions created by The Wall Street Journal and the Financial Times. Conscious to censorship, the Times established servers outside of China and affirmed that the website would uphold the paper's journalistic standards; the government of China had previously blocked articles from nytimes.com through the Great Firewall, and the website was blocked in China until August 2001 after then-general secretary Jiang Zemin met with journalists from The New York Times. Then-foreign editor Joseph Kahn assisted in the establishment of cn.nytimes.com, an effort that contributed to his appointment as executive editor in April 2022. In October 2012, 纽约时报中文 published an article detailing the wealth of then-premier Wen Jiabao's family. In response, the government of China blocked access to nytimes.com and cn.nytimes.com and references to the Times and Wen were censored on microblogging service Sina Weibo. In March 2015, a mirror of 纽约时报中文 and the website for GreatFire were the targets for a government-sanctioned distributed denial of service attack on GitHub in March 2015, disabling access to the service for several days. Chinese authorities requested the removal of The New York Times's news applications from the App Store in December 2016. Awards and recognition As of 2023, The New York Times has received 137 Pulitzer Prizes, the most of any publication. The New York Times is considered a newspaper of record in the United States.[l] The Times is the largest metropolitan newspaper in the United States; as of 2022, The New York Times is the second-largest newspaper by print circulation in the United States behind The Wall Street Journal. A study published in Science, Technology, & Human Values in 2013 found that The New York Times received more citations in academic journals than the American Sociological Review, Research Policy, or the Harvard Law Review. With sixteen million unique records, the Times is the third-most referenced source in Common Crawl, a collection of online material used in datasets such as GPT-3, behind Wikipedia and a United States patent database. The New Yorker's Max Norman wrote in March 2023 that the Times has shaped mainstream English usage. In a January 2018 article for The Washington Post, Margaret Sullivan stated that The New York Times affects the "whole media and political ecosystem". The New York Times's nascent success has led to concerns over media consolidation, particularly amid the decline of newspapers. In 2006, economists Lisa George and Joel Waldfogel examined the consequences of the Times's national distribution strategy and audience with circulation of local newspapers, finding that local circulation decreased among college-educated readers. The effect of The New York Times in this manner was observed in The Forum of Fargo-Moorhead, the newspaper of record for Fargo, North Dakota. Axios founder Jim VandeHei opined that the Times is "going to basically be a monopoly" in an opinion piece written by then-media columnist and former BuzzFeed News editor-in-chief Ben Smith; in the article, Smith cites the strength of The New York Times's journalistic workforce, broadening content, and the expropriation of Gawker editor-in-chief Choire Sicha, Recode editor-in-chief Kara Swisher, and Quartz editor-in-chief Kevin Delaney. Smith compared the Times to the New York Yankees during their 1927 season containing Murderers' Row. Controversies Since 2003, studies analyzing coverage of the Israeli–Palestinian conflict in the New York Times have demonstrated a bias against Palestinians and in favor of Israel.[m] The New York Times has received criticism for its coverage of the Gaza war and genocide. In April 2024, The Intercept reported that a November 2023 internal memorandum by Susan Wessling and Philip Pan instructed journalists to reduce using the terms "genocide" and "ethnic cleansing" and to avoid using the phrase "occupied territory" in the context of Palestinian land, "Palestine" except in rare circumstances, and the term "refugee camps" to describe areas of Gaza despite recognition from the United Nations. A spokesperson from the Times stated that issuing guidance was standard practice. An analysis by The Intercept noted that The New York Times described Israeli deaths as a massacre nearly sixty times, but had only described Palestinian deaths as a massacre once. Writers and editors have left the newspaper due to its coverage of events in Gaza, including Jazmine Hughes and Jamie Lauren Keiles. In December 2023, The New York Times published an investigation titled "'Screams Without Words': How Hamas Weaponized Sexual Violence on Oct. 7", alleging that Hamas weaponized sexual and gender-based violence during its armed incursion on Israel. The investigation was the subject of an article from The Intercept questioning the journalistic acumen of Anat Schwartz, a filmmaker involved in the inquiry who had no prior reporting experience and agreed with a post stating Israel should "violate any norm, on the way to victory", doubting the veracity of the opening claim that Gal Abdush was raped in a timespan disputed by her family, and alleging that the Times was pressured by the Committee for Accuracy in Middle East Reporting in America. The New York Times initiated an inquiry into the leaking of confidential information about the report to other outlets, which received criticism from NewsGuild of New York president Susan DeCarava for purported racial targeting; the Times's investigation was inconclusive, but found gaps in the way proprietary journalistic material is handled. The New York Times Building has been a site of protest action during the Gaza war and genocide, including a November 2023 sit-in demanding that The Times's editorial board publicly call for a ceasefire and accusing the media company of "complicity in laundering genocide", a February 29, 2024, protest and press conference following the release of The Intercept's critical investigation into the NYT "Screams Without Words" exposé, and an action on July 30, 2025, in which protesters spray-painted "NYT Lies, Gaza dies" on the building's glass facade. In addition, protesters blocked The New York Times's distribution center March 14, 2024 and executive editor Joseph Kahn's residence was splattered with red paint on August 25, 2025. The collective Writers Against the War on Gaza, which publishes the mock publication The New York War Crimes, has been associated with protests against The New York Times. On October 27, 2025, 300 writers—including scholars, journalists, and public intellectuals—pledged to boycott The New York Times and withhold contributions to the paper in protest of what they describe as its complicity in the Gaza genocide, demanding 1) a review of anti-Palestinian bias in the newsroom, 2) a retraction of "Screams Without Words", and 3) a call from the editorial board for a US arms embargo on Israel. Among the initial signatories, about 150 had previously contributed to the Times. The New York Times has received criticism regarding its coverage of transgender people. When it published an opinion piece by Weill Cornell Medicine professor Richard A. Friedman called "How Changeable Is Gender?" in August 2015, Vox's German Lopez criticized Friedman as suggesting that parents and doctors might be right in letting children suffer from severe dysphoria in case something changes down the line, and as implying that conversion therapy may work for transgender children. In February 2023, nearly one thousand current and former Times writers and contributors wrote an open letter addressed to standards editor Philip B. Corbett, criticizing the paper's coverage of transgender, non-binary, and gender-nonconforming people; some of the Times's articles have been cited in state legislatures attempting to justify criminalizing gender-affirming care. Contributors wrote in the open letter that "the Times has in recent years treated gender diversity with an eerily familiar mix of pseudoscience and euphemistic, charged language, while publishing reporting on trans children that omits relevant information about its sources."[n] According to former Times journalist Billie Jean Sweeney, a push for writers to challenge “every aspect of being trans”, ranging from gender-inclusive language to access to medical care, came from the top in 2022 after leadership was handed over to A. G. Sulzberger, Joe Kahn, and Carolyn Ryan; as part of an effort to win good will with the Trump campaign without incurring backlash from the general populace. The Times has continually denied any bias in its reporting, insisting that its coverage of “fiercely contested medical and legal debates” is fair and balanced, and that it would not tolerate journalists protesting its transgender coverage.

It was unclear who had set up the database, but it seemed to contain personal details that may have been cobbled together from multiple historic data breaches—including, perhaps, the trove from the 2024 breach of the background-checking service National Public Data. It is common for data brokers and cybercriminals to combine and recombine old datasets, but the scale and the potential quantity of Social Security numbers—even if only a fraction of them were real—was striking.“Every week, there’s another finding where it looks big on paper, but it's probably not very novel,” Pollock says. “So I was surprised when I started digging into the specific cases here to validate the data. In some cases, the identities in this data breach are at risk because they have been exposed, but they have not yet been exploited.”The data was hosted by the German cloud provider Hetzner. Since Pollock could not identify an owner of the database to contact, he notified Hetzner on January 16. The company, in turn, said it notified its customer, which removed the data on January 21.Hetzner did not provide WIRED with comment ahead of publication.The researchers did not download the entire dataset for analysis due to its size and sensitivity. Instead they worked with a sample of 2.8 million records—a tiny fraction of the total trove. By analyzing trends in the data, including the popularity of certain cultural references in passwords, they concluded that much of the data likely dates to the United States in roughly 2015. For example, passwords referencing One Direction, Fall Out Boy, and Taylor Swift were very common. Meanwhile, references to Blackpink, Katseye, and Btsarmy were just barely beginning to show up.Old data is still valuable for two reasons. First, people often reuse the same email address and password, or a variation of the password, across many different websites and services. This means that cybercriminals can keep trying the same login credentials for the same people over time. The second reason is that people's Social Security numbers are often linked to their most sensitive and high-stakes data but almost never change during their lifetimes. As a result, valid SSNs are one of the crown jewels of identity theft for attackers.In the sample of data the researchers reviewed, Pollock says that one in four Social Security numbers appeared to be valid and legitimate. The sample was too small to extrapolate to the entire dataset, but a quarter of all the records containing SSNs would be 675 million. A fraction of that would still represent a very significant set of Social Security numbers.To verify the data, UpGuard researchers contacted a handful of people whose data appeared in the leaked trove. Pollock emphasizes that one of the most concerning findings from speaking to those individuals was that not all of them have had their identities stolen or suffered hacks. In other words, there was information in the database that has not been exploited by cybercriminals—and potential victims don't necessarily know that their information has been exposed.The finding is a reminder, Pollock says, of how incidents like the 2015 US Office of Personnel Management breach or the 2017 breach of credit bureau Equifax create a long tail of uncertainty for anyone whose data was stolen. Similarly, he notes that recent erosion of safeguards that separated data within the US federal government creates privacy and security risks.“I do not at all think this is the data the DOGE group mishandled, but I do think that’s another example of how mistakes in how you handle data can have impacts for decades,” he says. “These are land mines that have been put down and then are dangerous forever.” A Vast Trove of Exposed Social Security Numbers May Put Millions at Risk of Identity Theft After years spent finding and investigating data breaches, Greg Pollock admits that when he comes across yet another exposed database full of passwords and Social Security numbers, “I come to it with some fatigue.” But Pollock, director of research at the cybersecurity company UpGuard, says he and his colleagues found an exposed, publicly accessible database online in January that appeared to contain a trove of Americans’ sensitive personal data so massive that his weariness lifted and they sprang to action to validate the finding.

Contents The Daily Telegraph The Daily Telegraph, known online and elsewhere as The Telegraph, is a British daily broadsheet conservative newspaper published in London by Telegraph Media Group and distributed in the United Kingdom and internationally. It was founded by Arthur B. Sleigh in 1855 as The Daily Telegraph and Courier. The Telegraph is considered a newspaper of record in the UK. The paper's motto, "Was, is, and will be", was included in its emblem which was used for over a century starting in 1858. In 2013, The Daily Telegraph and The Sunday Telegraph, which started in 1961, were merged, although the latter retains its own editor. Both papers are politically conservative and support the Conservative Party, although the Daily Telegraph was moderately liberal before the late 1870s. The Telegraph has had a number of news scoops, including an eyewitness account of the outbreak of the Second World War by a novice reporter, Clare Hollingworth, which has been described as "the scoop of the century"; the 2009 parliamentary expenses scandal, which led to a number of high-profile political resignations and for which the paper was named 2009 British Newspaper of the Year; its 2016 undercover investigation of the England football manager Sam Allardyce; and the Lockdown Files in 2023. In May 2025, an investment management firm, RedBird Capital Partners, announced plans to acquire the newspaper's publisher for £500 million (about US$674 million), but the deal collapsed in November 2025. History The Daily Telegraph and Courier was founded by Colonel Arthur B. Sleigh in June 1855 to air a personal grievance against the future commander-in-chief of the British Army, Prince George, Duke of Cambridge. Joseph Moses Levy, the owner of The Sunday Times, agreed to print the newspaper, and the first edition was published on 29 June 1855. The paper cost 2d and was four pages long. Nevertheless, the first edition stressed the quality and independence of its articles and journalists: "We shall be guided by a high tone of independent action." As the paper was not a success, Sleigh was unable to pay Levy the printing bill. Levy took over the newspaper, his aim being to produce a cheaper newspaper than his main competitors in London, the Daily News and The Morning Post, to expand the size of the overall market.[citation needed] Levy appointed his son, Edward Levy-Lawson, Lord Burnham, and Thornton Leigh Hunt to edit the newspaper. Lord Burnham relaunched the paper as The Daily Telegraph, with the slogan "the largest, best, and cheapest newspaper in the world". Hunt laid out the newspaper's principles in a memorandum sent to Levy: "We should report all striking events in science, so told that the intelligent public can understand what has happened and can see its bearing on our daily life and our future. The same principle should apply to all other events—to fashion, to new inventions, to new methods of conducting business". In 1876, Jules Verne published his novel Michael Strogoff, whose plot takes place during a fictional uprising and war in Siberia. Verne included among the book's characters a war correspondent of The Daily Telegraph, named Harry Blount—who is depicted as an exceptionally dedicated, resourceful and brave journalist, taking great personal risks to follow closely the ongoing war and bring accurate news of it to The Telegraph's readership, ahead of competing papers. In 1908, The Daily Telegraph printed an article in the form of an interview with Kaiser Wilhelm II of Germany that damaged Anglo-German relations and added to international tensions in the build-up to World War I. In 1928, the son of Baron Burnham, Harry Lawson Webster Levy-Lawson, 2nd Baron Burnham, sold the paper to William Berry, 1st Viscount Camrose, in partnership with his brother Gomer Berry, 1st Viscount Kemsley and Edward Iliffe, 1st Baron Iliffe. In 1937, the newspaper absorbed The Morning Post, which traditionally espoused a conservative position and sold predominantly amongst the retired officer class. Originally William Ewart Berry, 1st Viscount Camrose, bought The Morning Post with the intention of publishing it alongside The Daily Telegraph, but poor sales of the former led him to merge the two. For some years, the paper was retitled The Daily Telegraph and Morning Post before it reverted to just The Daily Telegraph. In the late 1930s, Victor Gordon Lennox, The Telegraph's diplomatic editor, published an anti-appeasement private newspaper The Whitehall Letter that received much of its information from leaks from Sir Robert Vansittart, the Permanent Under-Secretary of the Foreign Office, and Rex Leeper, the Foreign Office's Press Secretary. As a result, Gordon Lennox was monitored by MI5. In 1939, The Telegraph published Clare Hollingworth's scoop that Germany was to invade Poland. In November 1940, Fleet Street, with its close proximity to the river and docklands, was subjected to almost daily bombing raids by the Luftwaffe and The Telegraph started printing in Manchester at Kemsley House (now The Printworks entertainment venue), which was run by Camrose's brother Kemsley. Manchester quite often printed the entire run of The Telegraph when its Fleet Street offices were under threat. The name Kemsley House was changed to Thomson House in 1959. In 1986, printing of Northern editions of the Daily and Sunday Telegraph moved to Trafford Park and in 2008 to Newsprinters at Knowsley, Liverpool. During the Second World War, The Daily Telegraph covertly helped in the recruitment of code-breakers for Bletchley Park. The ability to solve The Telegraph's crossword in under 12 minutes was considered to be a recruitment test. The newspaper was asked to organise a crossword competition, after which each of the successful participants was contacted and asked if they would be prepared to undertake "a particular type of work as a contribution to the war effort". The competition itself was won by F. H. W. Hawes of Dagenham who finished the crossword in less than eight minutes. Both the Camrose (Berry) and Burnham (Levy-Lawson) families remained involved in management until Conrad Black took control in 1986. On the death of his father in 1954, Seymour Berry, 2nd Viscount Camrose assumed the chairmanship of the Daily Telegraph with his brother Michael Berry, Baron Hartwell as his editor-in-chief. During this period, the company saw the launch of sister paper The Sunday Telegraph in 1960. Canadian businessman Conrad Black, through companies controlled by him, bought the Telegraph Group in 1986. Black, through his holding company Ravelston Corporation, owned 78% of Hollinger Inc. which in turn owned 30% of Hollinger International. Hollinger International in turn owned the Telegraph Group and other publications such as the Chicago Sun-Times, the Jerusalem Post and The Spectator. On 18 January 2004, Black was dismissed as chairman of the Hollinger International board over allegations of financial wrongdoing. Black was also sued by the company. Later that day, it was reported that the Barclay brothers had agreed to purchase Black's 78% interest in Hollinger Inc. for £245m, giving them a controlling interest in the company, and to buy out the minority shareholders later. However, a lawsuit was filed by the Hollinger International board to try to block Black from selling his shares in Hollinger Inc. until an investigation into his dealings was completed. Black filed a countersuit but, eventually, United States judge Leo Strine sided with the Hollinger International board and blocked Black from selling his Hollinger Inc. shares to the twins. On 7 March 2004, the twins announced that they were launching another bid, this time just for The Daily Telegraph and its Sunday sister paper rather than all of Hollinger Inc. The then owner of the Daily Express, Richard Desmond, was also interested in purchasing the paper, selling his interest in several pornographic magazines to finance the initiative. Desmond withdrew in March 2004, when the price climbed above £600m, as did Daily Mail and General Trust plc a few months later on 17 June. In November 2004, The Telegraph celebrated the tenth anniversary of its website, Electronic Telegraph, now renamed www.telegraph.co.uk. The Electronic Telegraph launched in 1995 with The Daily Telegraph Guide to the Internet[citation needed] by writer Sue Schofield for an annual charge of £180.00. On 8 May 2006, the first stage of a major redesign of the website took place, with a wider page layout and greater prominence for audio, video and journalist blogs. On 10 October 2005, The Daily Telegraph relaunched to incorporate a tabloid sports section and a new standalone business section. The Daily Mail's star columnist and political analyst Simon Heffer left that paper in October 2005 to rejoin The Daily Telegraph, where he has become associate editor. Heffer has written two columns a week for the paper since late October 2005 and is a regular contributor to the news podcast. In November 2005, the first regular podcast service by a newspaper in the UK was launched. Just before Christmas 2005, it was announced that The Telegraph titles would be moving from Canada Place in Canary Wharf, to new offices at Victoria Plaza at 111 Buckingham Palace Road near Victoria Station in central London. The new office features a "hub and spoke" layout for the newsroom to produce content for print and online editions. In October 2006, with its relocation to Victoria, the company was renamed the Telegraph Media Group, repositioning itself as a multimedia company. On 2 September 2008, the Daily Telegraph was printed with colour on each page for the first time when it left Westferry for Newsprinters at Broxbourne, Hertfordshire, another arm of the Murdoch company. The paper is also printed in Liverpool and Glasgow by Newsprinters. In May 2009, the daily and Sunday editions published details of MPs' expenses. This led to a number of high-profile resignations from both the ruling Labour administration and the Conservative opposition. In June 2014, The Telegraph was criticised by Private Eye for its policy of replacing experienced journalists and news managers with less-experienced staff and search engine optimisers. On 26 October 2019, the Financial Times reported that the Barclay Brothers were about to put the Telegraph Media Group up for sale. The Financial Times also reported that the Daily Mail and General Trust (owner of the Daily Mail, The Mail on Sunday, Metro and Ireland on Sunday) would be interested in buying. The Daily Telegraph supported Liz Truss in the July–September 2022 Conservative Party leadership election. In July 2023, it was announced that Lloyds Banking Group had appointed Mike McTighe as chairman of Press Acquisitions Limited and May Corporation Limited in order to spearhead the sale of The Telegraph and The Spectator. In July 2014, the Daily Telegraph was criticised for carrying links on its website to pro-Kremlin articles supplied by a Russian state-funded publication that downplayed any Russian involvement in the downing of the passenger jet Malaysia Airlines Flight 17. These had featured on its website as part of a commercial deal, but were later removed. As of 2014,[needs update] the paper was paid £900,000 a year to include the supplement Russia Beyond the Headlines, a publication sponsored by the Rossiyskaya Gazeta, the Russian government's official newspaper. In February 2015, the chief political commentator of the Daily Telegraph, Peter Oborne, resigned. Oborne accused the paper of a "form of fraud on its readers" for its coverage of the bank HSBC in relation to a Swiss tax-dodging scandal that was widely covered by other news media. He alleged that editorial decisions about news content had been heavily influenced by the advertising arm of the newspaper because of commercial interests. Jay Rosen at New York University stated that Oborne's resignation statement was "one of the most important things a journalist has written about journalism lately". Oborne cited other instances of advertising strategy influencing the content of articles, linking the refusal to take an editorial stance on the repression of democratic demonstrations in Hong Kong to the Telegraph's support from China. Additionally, he said that favourable reviews of the Cunard cruise liner Queen Mary II appeared in the Telegraph, noting: "On 10 May last year The Telegraph ran a long feature on Cunard's Queen Mary II liner on the news review page. This episode looked to many like a plug for an advertiser on a page normally dedicated to serious news analysis. I again checked and certainly Telegraph competitors did not view Cunard's liner as a major news story. Cunard is an important Telegraph advertiser." In response, the Telegraph called Oborne's statement an "astonishing and unfounded attack, full of inaccuracy and innuendo". Later that month, Telegraph editor Chris Evans invited journalists at the newspaper to contribute their thoughts on the issue. Press Gazette reported later in 2015 that Oborne had joined the Daily Mail tabloid newspaper and The Telegraph had "issued new guidelines over the way editorial and commercial staff work together". In January 2017, the Telegraph Media Group had a higher number of upheld complaints than any other UK newspaper by its regulator IPSO. Most of these findings pertained to inaccuracy, as with other UK newspapers. In October 2017, a number of major western news organisations whose coverage had irked Beijing were excluded from Xi Jinping's speech event launching a new politburo. However, the Daily Telegraph had been granted an invitation to the event. In April 2019, Business Insider reported The Telegraph had partnered with Facebook to publish articles "downplaying 'technofears' and praising the company". The paper published premature obituaries for Cockie Hoogterp,[when?] the second wife of Baron Blixen, Dave Swarbrick in 1999, and Dorothy Southworth Ritter, the widow of Tex Ritter and mother of John Ritter, in August 2001. Editors for both the Daily Telegraph and the Sunday Telegraph have been criticised by Guardian columnist Owen Jones for publishing and authoring articles which espouse Cultural Marxism, an antisemitic conspiracy theory. In 2018, Allister Heath, the editor of the Sunday Telegraph wrote that "Cultural Marxism is running rampant." Assistant comment editor of the Daily Telegraph Sherelle Jacobs also used the term in 2019. The Daily Telegraph also published an anonymous civil servant who stated: "There is a strong presence of Anglophobia, combined with cultural Marxism that runs through the civil service." In January 2019, the paper published an article written by Camilla Tominey titled "Police called in after Scout group run from mosque is linked to Islamic extremist and Holocaust denier" in which it was reported that the police were investigating Ahammed Hussain, the Leader of the Scout Group at the Lewisham Islamic Centre, because he had links to extremist Muslim groups that promoted terrorism and antisemitism. In January 2020, the paper issued an official apology and accepted that the article contained many falsehoods, and that Hussain had never supported or promoted terrorism, or been antisemitic. The paper paid Hussain damages and costs. In a letter sent to Hussain's lawyers accompanying the text of their published apology, the newspaper's lawyers wrote: "The article was published by our client following receipt of information in good faith from the Scout Association and the Henry Jackson Society; nevertheless our client now accepts that the article (using that expression to refer to both print and online versions) is defamatory of your client and will apologise to him for publishing it." In 2016, the Hong Kong Free Press reported that The Daily Telegraph was receiving £750,000 annually to carry a supplement called 'China Watch' as part of a commercial deal with Chinese state-run newspaper China Daily. The Guardian reported in 2018 that the China Watch supplement was being carried by The Telegraph along with other newspapers of record such as The New York Times, The Wall Street Journal and Le Figaro. The Telegraph published the supplement once a month in print, and published it online at least until March 2020. In April 2020, The Telegraph removed China Watch from its website, along with another advertisement feature section by Chinese state-run media outlet People's Daily Online. The paper had run many pieces critical of China since the start of the COVID-19 pandemic. In January 2021, the British press regulator, the Independent Press Standards Organisation, ordered The Daily Telegraph to publish a correction to two "significantly misleading" claims in a comment article published by Toby Young. The July 2020 article "When we have herd immunity Boris will face a reckoning on this pointless and damaging lockdown," which spread COVID-19 misinformation that the common cold provided "natural immunity" to COVID-19 and that London was "probably approaching herd immunity". The regulator said that a correction was appropriate rather than a more serious response due to the level of scientific uncertainty at the time the comment was published. At the time of the ruling, The Telegraph had removed the comment article but had not issued a correction. The Telegraph has published multiple columns and news articles which promote pseudoscientific views on climate change, and misleadingly cast the subject of climate change as a subject of active scientific debate when there is a scientific consensus on climate change. It has published columns about the "conspiracy behind the Anthropogenic Global Warming myth", described climate scientists as "white-coated prima donnas and narcissists," and claimed that "global warming causes about as much damage as benefits." In 2015, a Telegraph news article incorrectly claimed that scientists predicted a mini-ice age by 2030. Climate change denying journalist James Delingpole was first to use "Climategate" on his Telegraph blog for a manufactured controversy where emails were leaked from climate scientists ahead of the Copenhagen climate summit and misleadingly presented to give the appearance that the climate scientists were engaged in fraud. In 2014, The Telegraph was one of several media titles to give evidence to the House of Commons Select Committee 'Communicating climate science'. The paper told MPs they believe climate change is happening and humans play a role in it. Editors told the committee, "we believe that the climate is changing, that the reason for that change includes human activity, but that human ingenuity and adaptability should not be ignored in favour of economically damaging prescriptions." In November 2023, the journalist and climate activist group DeSmog published its judgements for coverage of environmental topics in 171 of The Telegraph's opinion pieces from April to October 2023. DeSmog stated that of these 171 pieces, 85 per cent were categorised as "anti-green", defined as "attacking climate policy, questioning climate science and ridiculing environmental groups." The Daily Telegraph, in particular its columnist and former editor Charles Moore, were staunch supporters of Owen Paterson, a former MP and minister who resigned after it was found that he had breached advocacy rules to lobby ministers for fees. A plan to overhaul the Commons standard and spare Paterson from being suspended and a possible recall petition that follows was leaked to the newspaper and it was "approvingly" splashed across the paper's front page. Boris Johnson flew back from the COP 26 summit in Glasgow to attend a Telegraph journalists' reunion at the Garrick and left the club with Moore the same evening. In June 2023, The Guardian and other newspapers reported that, following a breakdown in discussions relating to a financial dispute, Lloyds Bank was planning to take control of the companies owning the Telegraph titles and the Spectator and sell them off. Representatives of the Barclay family have described the reports as "irresponsible". By 20 October, a sale of the publications had been initiated after bankers seized control. Lloyds appointed receivers and started shopping the brands to bidders. By November, it was revealed that the bid had been agreed upon by RedBird IMI, a joint venture between RedBird Capital Partners and International Media Investments, a firm based in the United Arab Emirates and owned by Sheikh Mansour bin Zayed Al Nahyan. The bid would see the firm take over The Telegraph, while allowing the Barclay family to repay a debt of £1.2 billion to Lloyds Bank. Conservative MPs raised national security concerns, and pushed the government to investigate the bid, as the United Arab Emirates had a poor reputation for freedom of speech. Culture secretary Lucy Frazer issued a public interest intervention notice on 30 November, preventing the group from taking over without further scrutiny from the media regulator Ofcom over potential breaches of media standards. Conservative MPs also called on Deputy Prime Minister Oliver Dowden to use the National Security and Investment Act 2021 to investigate the Emirati-backed bid. Chairman Andrew Neil threatened to quit if the sale was approved, saying: "You cannot have a major mainstream newspaper group owned by an undemocratic government or dictatorship where no one has a vote." Fraser Nelson, editor of The Spectator, which would be included in the sale, also opposed the move, saying, "the very reason why a foreign government would want to buy a sensitive asset is the very reason why a national government should be wary of selling them." In March 2024, the Lords voted in a new law, under which restrictions were imposed on foreign governments regarding the ownership of British newspapers and magazines, including only being allowed up to a 0.1 per cent stake. In April 2024, the UK government effectively banned RedBird IMI from taking over The Telegraph and The Spectator by introducing new laws which prevented foreign governments from owning British newspapers. RedBird also confirmed it would withdraw its takeover plans, saying they were "no longer feasible". In April 2024, RedBird IMI confirmed to put up The Telegraph for sale again and to begin open auction. However, the Abu Dhabi fund suggested that it seek to recoup the £600 million it spent acquiring the newspaper, or will otherwise retain some involvement. The Telegraph was left in limbo, as the staff remained blocked from taking strategic decisions. The owner of The New York Sun, Dovid Efune came up as a leading bidder, but struggled to take over the paper. The Columbia Journalism Review dubbed it as "the newspaper auction from hell". On 17 January 2025, David Castelblanco, a partner at the Abu Dhabi fund RedBird, urged The Telegraph to make significant job cuts, including over 100 non-editorial roles. He also advised the executives to halt planned editorial investments, which included expansions of the US newsroom. The intervention was likely to raise concerns about foreign interference and fuels fears of foreign influence in the decision-making process of The Telegraph. On 19 January, Sir Iain Duncan Smith stated that the UAE should not be allowed to acquire the British newspaper. He also accused the UK government of "foot-dragging" the process due to fear of upsetting the Emirates, and asked for an explanation about the Digital Markets, Competition and Consumers Act 2024. Sir Ed Davey also called for the Cultural Secretary Lisa Nandy to set a deadline for The Telegraph's sale, and urged the ministers to ensure that the Abu Dhabi fund is "not improperly meddling in the meantime". In May 2025, Conservative MPs rebelled against their party's leadership to block Lisa Nandy's proposal allowing the UAE to acquire up to 15% of The Telegraph. This move came as RedBird Capital sought to lead a new consortium to acquire the newspaper. Lord Forsyth accused Lisa Nandy of surrendering to lobbying, raising concerns over foreign state influence, a potential risk to press freedom and independent journalism. Despite the objections, the deal proceeded, and on 23 May, RedBird IMI agreed to acquire The Telegraph for £500 million ($673 million). On 14 November 2025, RedBird dropped their bid to buy the papers due to negative media coverage related to the deal and regulatory scrutiny in the UK. A deal that was struck on 22 November 2025 would see its ownership transferred to Daily Mail owner DMGT. Circulation It had a circulation of 270,000 in 1856, and 240,000 in 1863. It had a circulation of 1,393,094 in 1968, and 1,358,875 in 1978. It had a circulation of 1,439,000 in 1980, and 1,235,000 in 1984. It had a circulation of 1,133,173 in 1988. The paper had a circulation of 363,183 in December 2018, not including bulk sales. It descended further until it withdrew from newspaper circulation audits in 2020. The bulk of its readership has moved online; the Telegraph Media Group reported a subscription number of 1,035,710 for December 2023, composed of 117,586 for its print edition, 688,012 for its digital version and 230,112 for other subscriptions. Political stance The Daily Telegraph supported Whig, and moderate liberal ideas, before the late 1870s. The Daily Telegraph is politically conservative and has endorsed the Conservative Party at every UK general election since 1945. The personal links between the paper's editors and the leadership of the Conservative Party, along with the paper's generally right-wing stance and influence over Conservative activists, have led the paper commonly to be referred to, especially in Private Eye, as the Torygraph. When the Barclay brothers purchased the Telegraph Group for around £665 million in late June 2004, Sir David Barclay suggested that The Daily Telegraph might no longer be the "house newspaper" of the Conservatives in the future. In an interview with The Guardian, he said: "Where the government are right we shall support them." The editorial board endorsed the Conservative Party in the 2005 general election.[citation needed] During the 2014 Scottish independence referendum, the paper supported the Better Together "No" Campaign. Alex Salmond, the former leader of the SNP, called The Telegraph "extreme" on Question Time in September 2015. In the 2016 United Kingdom European Union membership referendum, it endorsed voting to leave the EU. In December 2015, The Daily Telegraph was fined £30,000 for "sending an unsolicited email to hundreds of thousands of its subscribers, urging them to vote for the Conservatives." During the 2019 Conservative Party leadership election, The Daily Telegraph endorsed their former columnist Boris Johnson. In 2019, former columnist Graham Norton, who had left the paper in late 2018, said "about a year before I left, it took a turn" and criticised it for "toxic" political stances, namely for a piece defending US Supreme Court then-nominee Brett Kavanaugh and for being "a mouthpiece for Boris Johnson" whose columns were allegedly published with "no fact-checking at all". In 2012, prior to the legalisation of same-sex marriage in the United Kingdom, The Telegraph published an editorial stating that it was a "pointless distraction" as "many [gay couples] already avail themselves of the civil partnerships introduced by Labour". The Telegraph wrote in another editorial that same year that it feared that changing "the law on gay marriage risks inflaming anti-homosexual bigotry". In 2015, following Sir Elton John's boycott of Dolce & Gabbana after its founders criticised IVF and same-sex adoptions, former editor Charles Moore wrote an article in the paper saying a "gay rights sharia" was dictating what the LGBT+ community should believe. He suggested the public reaction to the comments was designed to "silence debate" and prevent support for "traditional views of parenthood". Moore also said "adult transgender mutilation" should not be celebrated. Moore has previously expressed his views that civil partnerships achieved a "balance" for heterosexual and homosexual couples. In 2013, he wrote: "Respectable people are truly terrified of being thought anti-homosexual. In a way, they are right to be, because attacking people for their personal preferences can be a nasty thing." In 2015, Michael Segalov wrote an article for The Telegraph saying then-Prime Minister Theresa May needed to be "serious about LGBT equality". After the Orlando nightclub shooting in June 2016, The Telegraph published an article by Stonewall CEO Ruth Hunt that said the attack on a gay nightclub "grew out of everyday homophobia". The same year, Telegraph Executive Director Lord Black was awarded Peer of the Year at the 2016 PinkNews Awards for his campaigning on LGBT rights. The newspaper also featured an article written by Maria Munir about their experience coming out to President Barack Obama as non-binary. In 2017, Rachel Cunliffe wrote in the paper that "bathroom bills" in Texas – which were criticised as being transphobic – were "a Kafkaesque state intrusion". PinkNews has criticised The Telegraph for its coverage of trans people, suggesting several articles and a billboard campaign were either misleading or transphobic. In 2017, the newspaper published an article by Allison Pearson titled: "Will our spineless politicians' love affair with LGBT ever end?", which argued that asking NHS patients their sexual orientation was unnecessary. In 2018, it published another article by Pearson headlined "The tyranny of the transgender minority has got to be stopped." In 2025, two members of the campaign group Trans Kids Deserve Better climbed The Telegraph's office building to protest media coverage of trans issues, saying the paper had published 150 articles about trans people and had treated trans children as "just another scapegoat". Sister publications The Daily Telegraph's sister Sunday paper was founded in 1961. The writer Sir Peregrine Worsthorne is probably the best known journalist associated with the title (1961–1997),[according to whom?] eventually being editor for three years from 1986. In 1989, the Sunday title was briefly merged into a seven-day operation under Max Hastings's overall control. Circulation of The Sunday Telegraph in July 2010 was 505,214 (ABC). Young Telegraph was a weekly section of The Daily Telegraph published as a 14-page supplement in the weekend edition of the newspaper. Young Telegraph featured a mixture of news, features, cartoon strips and product reviews aimed at 8–12-year-olds. It was edited by Damien Kelleher (1993–1997) and Kitty Melrose (1997–1999). Launched in 1990, the award-winning supplement also ran original serialised stories featuring popular brands such as Young Indiana Jones and the British children's sitcom Maid Marian and Her Merry Men. It featured the cartoon "Mad Gadget" by Chris Winn, and a computer game Mad Gadget: Lost In Time (1993) and a book Mad Gadget: Gadget Mad (1995) were produced. In 1995, an interactive spin-off called Electronic Young Telegraph (EYT) was launched on floppy disk. Described as an interactive computer magazine for children, Electronic Young Telegraph was edited by Adam Tanswell, who led the relaunch of the product on CD-Rom in 1998. Electronic Young Telegraph featured original content including interactive quizzes, informative features and computer games, as well as entertainment news and reviews. It was later re-branded as T:Drive in 1999. Telegraph.co.uk is the online version of the newspaper. It uses the banner title The Telegraph and includes articles from the print editions of The Daily Telegraph and The Sunday Telegraph, as well as web-only content such as breaking news, features, picture galleries and blogs. It was named UK Consumer Website of the Year in 2007 and Digital Publisher of the year in 2009 by the Association of Online Publishers. The site is overseen by Kate Day, digital director of Telegraph Media Group. Other staff include Shane Richmond, head of technology (editorial), and Ian Douglas, head of digital production. Starting in November 2012, international customers accessing the Telegraph.co.uk site would have to sign up for a subscription package. Visitors had access to 20 free articles a month before having to subscribe for unlimited access. In March 2013, the pay meter system was also rolled out in the UK. The site, which has been the focus of the group's efforts to create an integrated news operation producing content for print and online from the same newsroom, completed a relaunch during 2008 involving the use of the Escenic content management system, popular among northern European and Scandinavian newspaper groups. Telegraph TV is a video on demand service run by The Daily Telegraph and the Sunday Telegraph. It is hosted on The Telegraph's website, telegraph.co.uk. Telegraph.co.uk became the most popular UK newspaper site in April 2008. It was overtaken by Guardian.co.uk in April 2009 and later by "Mail Online". In December 2010, "Telegraph.co.uk" was the third most visited British newspaper website with 1.7 million daily browsers compared to 2.3 million for "Guardian.co.uk" and nearly 3 million for "Mail Online". In October 2023, "Telegraph.co.uk" was the tenth most visited UK newspaper site, with 13.8 million monthly visits, compared to the most popular, the BBC, with 38.3 million. The website was launched, under the name electronic telegraph at midday on 15 November 1994 at the headquarters of The Daily Telegraph at Canary Wharf in London Docklands with Ben Rooney as its first editor. It was Europe's first daily web-based newspaper. At this time, the modern internet was still in its infancy, with as few as 10,000 websites estimated to have existed at the time – compared to more than 100 billion by 2009. In 1994, only around 1% of the British population (some 600,000 people) had internet access at home, compared to more than 80% in 2009. Initially, the site published only the top stories from the print edition of the newspaper but it gradually increased its coverage until virtually all of the newspaper was carried online and the website was also publishing original material. The website, hosted on a Sun Microsystems Sparc 20 server and connected via a 64 kbit/s leased line from Demon Internet, was edited by Ben Rooney.[citation needed] An early coup for the site was the publication of articles by Ambrose Evans-Pritchard on Bill Clinton and the Whitewater controversy. The availability of the articles online brought a large American audience to the site. In 1997, the Clinton administration issued a 331-page report that accused Evans-Pritchard of peddling "right-wing inventions". Derek Bishton, who by then had succeeded Rooney as editor, later wrote: "In the days before ET it would have been highly unlikely that anyone in the US would have been aware of Evans-Pritchard's work – and certainly not to the extent that the White House would be forced to issue such a lengthy rebuttal." Bishton, who later became consulting editor for Telegraph Media Group, was followed as editor by Richard Burton, who was made redundant in August 2006. Edward Roussel replaced Burton. My Telegraph offers a platform for readers to have their own blog, save articles, and network with other readers. Launched in May 2007, My Telegraph won a Cross Media Award from international newspaper organisation IFRA in October 2007. One of the judges, Robert Cauthorn, described the project as "the best deployment of blogging yet seen in any newspaper anywhere in the world".[citation needed] Notable stories In December 2010, Telegraph reporters posing as constituents secretly recorded Business Secretary Vince Cable. In an undisclosed part of the transcript given to the BBC's Robert Peston by a whistleblower unhappy that The Telegraph had not published Cable's comments in full, Cable stated in reference to Rupert Murdoch's News Corporation takeover bid for BSkyB, "I have declared war on Mr Murdoch and I think we are going to win." Following this revelation, Cable had his responsibility for media affairs – including ruling on Murdoch's takeover plans – withdrawn from his role as business secretary. In May 2011, the Press Complaints Commission upheld a complaint regarding The Telegraph's use of subterfuge: "On this occasion, the commission was not convinced that the public interest was such as to justify proportionately this level of subterfuge." In July 2011, a firm of private investigators hired by The Telegraph to track the source of the leak concluded "strong suspicion" that two former Telegraph employees who had moved to News International, one of them Will Lewis, had gained access to the transcript and audio files and leaked them to Peston. In May 2009, The Daily Telegraph obtained a full copy of all the expenses claims of British Members of Parliament. The Telegraph began publishing, in instalments from 8 May 2009, certain MPs' expenses. The Telegraph justified the publication of the information because it contended that the official information due to be released would have omitted key information about redesignating of second-home nominations. This led to a number of high-profile resignations from both the ruling Labour administration and the Conservative opposition. In September 2016, Telegraph reporters posing as businessmen filmed England manager Sam Allardyce offering to give advice on how to get around on FA rules on player third party ownership and negotiating a £400,000 deal. The investigation saw Allardyce leave his job by mutual consent on 27 September and making the statement "entrapment has won". Reception and historical value Denise Bates included The Daily Telegraph in a list of national newspapers which, because of the quality of their reporting, or the extent of their audience, stand out and are likely to be used for historical research. The editors of Encyclopaedia Britannica said that The Daily Telegraph has consistently had a "high standard of reporting". The Daily Telegraph was renowned for its foreign correspondents. According to the DNCJ, during the nineteenth century, The Daily Telegraph had excellent coverage of the arts. In 1989, Nicholas and Erbach said that The Daily Telegraph is factually accurate, and that its reputation for being so extends outside the country. The Daily Telegraph has been named the National Newspaper of the Year in 2009, 1996 and 1993, while The Sunday Telegraph won the same award in 1999. Its investigation on the 2009 expenses scandal was named the "Scoop of the Year" in 2009, with William Lewis winning "Journalist of the Year". The Telegraph won "Team of the Year" in 2004 for its coverage of the Iraq War. The paper also won "Columnist of the Year" three years' running from 2002 to 2004: Zoë Heller (2002), Robert Harris (2003) and Boris Johnson (2004). Charity and fundraising work In 1979, following a letter in The Daily Telegraph and a Government report highlighting the shortfall in care available for premature babies, Bliss, the special care baby charity, was founded. In 2009, as part of the Bliss 30th birthday celebrations, the charity was chosen as one of four beneficiaries of the newspaper's Christmas Charity Appeal. In February 2010, a cheque was presented to Bliss for £120,000. In 2014, The Telegraph designed a newspaper-themed Paddington Bear statue, one of fifty located around London prior to the release of the film Paddington, which was auctioned to raise funds for the National Society for the Prevention of Cruelty to Children (NSPCC).

Contents Black hole A black hole is an astronomical body so compact that its gravity prevents anything, including light, from escaping. Albert Einstein's theory of general relativity predicts that a sufficiently compact mass will form a black hole. The boundary of no escape is called the event horizon. In general relativity, a black hole's event horizon seals an object's fate but produces no locally detectable change when crossed. General relativity also predicts that every black hole should have a central singularity, where the curvature of spacetime is infinite. In many ways, a black hole acts like an ideal black body, as it reflects no light. Quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly. Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. In 1916, Karl Schwarzschild found the first modern solution of general relativity that would characterise a black hole. Due to his influential research, the Schwarzschild metric is named after him. David Finkelstein, in 1958, first interpreted Schwarzschild's model as a region of space from which nothing can escape. Black holes were long considered a mathematical curiosity; it was not until the 1960s that theoretical work showed they were a generic prediction of general relativity. The first black hole known was Cygnus X-1, identified by several researchers independently in 1971. Black holes typically form when massive stars collapse at the end of their life cycle. After a black hole has formed, it can grow by absorbing mass from its surroundings. Supermassive black holes of millions of solar masses may form by absorbing other stars and merging with other black holes, or via direct collapse of gas clouds. There is consensus that supermassive black holes exist in the centres of most galaxies. The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light. Matter falling toward a black hole can form an accretion disk of infalling plasma, heated by friction and emitting light. In extreme cases, this creates a quasar, some of the brightest objects in the universe. Merging black holes can also be detected by observation of the gravitational waves they emit. If other stars are orbiting a black hole, their orbits can be used to determine the black hole's mass and location. Such observations can be used to exclude possible alternatives such as neutron stars. In this way, astronomers have identified numerous stellar black hole candidates in binary systems and established that the radio source known as Sagittarius A*, at the core of the Milky Way galaxy, contains a supermassive black hole of about 4.3 million solar masses. History The idea of a body so massive that even light could not escape was first proposed in the late 18th century by English astronomer and clergyman John Michell and independently by French scientist Pierre-Simon Laplace. Both scholars proposed very large stars in contrast to the modern concept of an extremely dense object. Michell's idea, in a short part of a letter published in 1784, calculated that a star with the same density but 500 times the radius of the sun would not let any emitted light escape; the surface escape velocity would exceed the speed of light.: 122 Michell correctly hypothesized that such supermassive but non-radiating bodies might be detectable through their gravitational effects on nearby visible bodies. In 1796, Laplace mentioned that a star could be invisible if it were sufficiently large while speculating on the origin of the Solar System in his book Exposition du Système du Monde. Franz Xaver von Zach asked Laplace for a mathematical analysis, which Laplace provided and published in a journal edited by von Zach. In 1905, Albert Einstein showed that the laws of electromagnetism would be invariant under a Lorentz transformation: they would be identical for observers travelling at different velocities relative to each other. This discovery became known as the principle of special relativity. Although the laws of mechanics had already been shown to be invariant, gravity remained yet to be included.: 19 In 1907, Einstein published a paper proposing his equivalence principle, the hypothesis that inertial mass and gravitational mass have a common cause. Using the principle, Einstein predicted the redshift and half of the lensing effect of gravity on light; the full prediction of gravitational lensing required development of general relativity.: 19 By 1915, Einstein refined these ideas into his general theory of relativity, which explained how matter affects spacetime, which in turn affects the motion of other matter. This formed the basis for black hole physics. Only a few months after Einstein published the field equations describing general relativity, astrophysicist Karl Schwarzschild set out to apply the idea to stars. He assumed spherical symmetry with no spin and found a solution to Einstein's equations.: 124 A few months after Schwarzschild, Johannes Droste, a student of Hendrik Lorentz, independently gave the same solution. At a certain radius from the center of the mass, the Schwarzschild solution became singular, meaning that some of the terms in the Einstein equations became infinite. The nature of this radius, which later became known as the Schwarzschild radius, was not understood at the time. Many physicists of the early 20th century were skeptical of the existence of black holes. In a 1926 popular science book, Arthur Eddington critiqued the idea of a star with mass compressed to its Schwarzschild radius as a flaw in the then-poorly-understood theory of general relativity.: 134 In 1939, Einstein himself used his theory of general relativity in an attempt to prove that black holes were impossible. His work relied on increasing pressure or increasing centrifugal force balancing the force of gravity so that the object would not collapse beyond its Schwarzschild radius. He missed the possibility that implosion would drive the system below this critical value.: 135 By the 1920s, astronomers had classified a number of white dwarf stars as too cool and dense to be explained by the gradual cooling of ordinary stars. In 1926, Ralph Fowler showed that quantum-mechanical degeneracy pressure was larger than thermal pressure at these densities.: 145 In 1931, Subrahmanyan Chandrasekhar calculated that a non-rotating body of electron-degenerate matter below a certain limiting mass is stable, and by 1934 he showed that this explained the catalog of white dwarf stars.: 151 When Chandrasekhar announced his results, Eddington pointed out that stars above this limit would radiate until they were sufficiently dense to prevent light from exiting, a conclusion he considered absurd. Eddington and, later, Lev Landau argued that some yet unknown mechanism would stop the collapse. In the 1930s, Fritz Zwicky and Walter Baade studied stellar novae, focusing on exceptionally bright ones they called supernovae. Zwicky promoted the idea that supernovae produced stars with the density of atomic nuclei—neutron stars—but this idea was largely ignored.: 171 In 1939, based on Chandrasekhar's reasoning, J. Robert Oppenheimer and George Volkoff predicted that neutron stars below a certain mass limit, later called the Tolman–Oppenheimer–Volkoff limit, would be stable due to neutron degeneracy pressure. Above that limit, they reasoned that either their model would not apply or that gravitational contraction would not stop.: 380 John Archibald Wheeler and two of his students resolved questions about the model behind the Tolman–Oppenheimer–Volkoff (TOV) limit. Harrison and Wheeler developed the equations of state relating density to pressure for cold matter all the way through electron degeneracy and neutron degeneracy. Masami Wakano and Wheeler then used the equations to compute the equilibrium curve for stars, relating mass to circumference. They found no additional features that would invalidate the TOV limit. This meant that the only thing that could prevent black holes from forming was a dynamic process ejecting sufficient mass from a star as it cooled.: 205 The modern concept of black holes was formulated by Robert Oppenheimer and his student Hartland Snyder in 1939.: 80 In the paper, Oppenheimer and Snyder solved Einstein's equations of general relativity for an idealized imploding star, in a model later called the Oppenheimer–Snyder model, then described the results from far outside the star. The implosion starts as one might expect: the star material rapidly collapses inward. However, as the density of the star increases, gravitational time dilation increases and the collapse, viewed from afar, seems to slow down further and further until the star reaches its Schwarzschild radius, where it appears frozen in time.: 217 In 1958, David Finkelstein identified the Schwarzschild surface as an event horizon, calling it "a perfect unidirectional membrane: causal influences can cross it in only one direction". In this sense, events that occur inside of the black hole cannot affect events that occur outside of the black hole. Finkelstein created a new reference frame to include the point of view of infalling observers.: 103 Finkelstein's new frame of reference allowed events at the surface of an imploding star to be related to events far away. By 1962 the two points of view were reconciled, convincing many skeptics that implosion into a black hole made physical sense.: 226 The era from the mid-1960s to the mid-1970s was the "golden age of black hole research", when general relativity and black holes became mainstream subjects of research.: 258 In this period, more general black hole solutions were found. In 1963, Roy Kerr found the exact solution for a rotating black hole. Two years later, Ezra Newman found the cylindrically symmetric solution for a black hole that is both rotating and electrically charged. In 1967, Werner Israel found that the Schwarzschild solution was the only possible solution for a nonspinning, uncharged black hole, meaning that a Schwarzschild black hole would be defined by its mass alone. Similar identities were later found for Reissner-Nordstrom and Kerr black holes, defined only by their mass and their charge or spin respectively. Together, these findings became known as the no-hair theorem, which states that a stationary black hole is completely described by the three parameters of the Kerr–Newman metric: mass, angular momentum, and electric charge. At first, it was suspected that the strange mathematical singularities found in each of the black hole solutions only appeared due to the assumption that a black hole would be perfectly spherically symmetric, and therefore the singularities would not appear in generic situations where black holes would not necessarily be symmetric. This view was held in particular by Vladimir Belinski, Isaak Khalatnikov, and Evgeny Lifshitz, who tried to prove that no singularities appear in generic solutions, although they would later reverse their positions. However, in 1965, Roger Penrose proved that general relativity without quantum mechanics requires that singularities appear in all black holes. Astronomical observations also made great strides during this era. In 1967, Antony Hewish and Jocelyn Bell Burnell discovered pulsars and by 1969, these were shown to be rapidly rotating neutron stars. Until that time, neutron stars, like black holes, were regarded as just theoretical curiosities, but the discovery of pulsars showed their physical relevance and spurred a further interest in all types of compact objects that might be formed by gravitational collapse. Based on observations in Greenwich and Toronto in the early 1970s, Cygnus X-1, a galactic X-ray source discovered in 1964, became the first astronomical object commonly accepted to be a black hole. Work by James Bardeen, Jacob Bekenstein, Carter, and Hawking in the early 1970s led to the formulation of black hole thermodynamics. These laws describe the behaviour of a black hole in close analogy to the laws of thermodynamics by relating mass to energy, area to entropy, and surface gravity to temperature. The analogy was completed: 442 when Hawking, in 1974, showed that quantum field theory implies that black holes should radiate like a black body with a temperature proportional to the surface gravity of the black hole, predicting the effect now known as Hawking radiation. While Cygnus X-1, a stellar-mass black hole, was generally accepted by the scientific community as a black hole by the end of 1973, it would be decades before a supermassive black hole would gain the same broad recognition. Although, as early as the 1960s, physicists such as Donald Lynden-Bell and Martin Rees had suggested that powerful quasars in the center of galaxies were powered by accreting supermassive black holes, little observational proof existed at the time. However, the Hubble Space Telescope, launched decades later, found that supermassive black holes were not only present in these active galactic nuclei, but that supermassive black holes in the center of galaxies were ubiquitous: Almost every galaxy had a supermassive black hole at its center, many of which were quiescent. In 1999, David Merritt proposed the M–sigma relation, which related the dispersion of the velocity of matter in the center bulge of a galaxy to the mass of the supermassive black hole at its core. Subsequent studies confirmed this correlation. Around the same time, based on telescope observations of the velocities of stars at the center of the Milky Way galaxy, independent work groups led by Andrea Ghez and Reinhard Genzel concluded that the compact radio source in the center of the galaxy, Sagittarius A*, was likely a supermassive black hole. On 11 February 2016, the LIGO Scientific Collaboration and Virgo Collaboration announced the first direct detection of gravitational waves, named GW150914, representing the first observation of a black hole merger. At the time of the merger, the black holes were approximately 1.4 billion light-years away from Earth and had masses of 30 and 35 solar masses.: 6 In 2017, Rainer Weiss, Kip Thorne, and Barry Barish, who had spearheaded the project, were awarded the Nobel Prize in Physics for their work. Since the initial discovery in 2015, hundreds more gravitational waves have been observed by LIGO and another interferometer, Virgo. On 10 April 2019, the first direct image of a black hole and its vicinity was published, following observations made by the Event Horizon Telescope (EHT) in 2017 of the supermassive black hole in Messier 87's galactic centre. In 2022, the Event Horizon Telescope collaboration released an image of the black hole in the center of the Milky Way galaxy, Sagittarius A*; The data had been collected in 2017. In 2020, the Nobel Prize in Physics was awarded for work on black holes. Andrea Ghez and Reinhard Genzel shared one-half for their discovery that Sagittarius A* is a supermassive black hole. Penrose received the other half for his work showing that the mathematics of general relativity requires the formation of black holes. Cosmologists lamented that Hawking's extensive theoretical work on black holes would not be honored since he died in 2018. In December 1967, a student reportedly suggested the phrase black hole at a lecture by John Wheeler; Wheeler adopted the term for its brevity and "advertising value", and Wheeler's stature in the field ensured it quickly caught on, leading some to credit Wheeler with coining the phrase. However, the term was used by others around that time. Science writer Marcia Bartusiak traces the term black hole to physicist Robert H. Dicke, who in the early 1960s reportedly compared the phenomenon to the Black Hole of Calcutta, notorious as a prison where people entered but never left alive. The term was used in print by Life and Science News magazines in 1963, and by science journalist Ann Ewing in her article "'Black Holes' in Space", dated 18 January 1964, which was a report on a meeting of the American Association for the Advancement of Science held in Cleveland, Ohio. Definition A black hole is generally defined as a region of spacetime from which no information-carrying signals or objects can escape. However, verifying an object as a black hole by this definition would require waiting for an infinite time and at an infinite distance from the black hole to verify that indeed, nothing has escaped, and thus cannot be used to identify a physical black hole. Broadly, physicists do not have a precisely-agreed-upon definition of a black hole. Among astrophysicists, a black hole is a compact object with a mass larger than four solar masses. A black hole may also be defined as a reservoir of information: 142 or a region where space is falling inwards faster than the speed of light. Properties The no-hair theorem postulates that, once it achieves a stable condition after formation, a black hole has only three independent physical properties: mass, electric charge, and angular momentum; the black hole is otherwise featureless. If the conjecture is true, any two black holes that share the same values for these properties, or parameters, are indistinguishable from one another. The degree to which the conjecture is true for real black holes is currently an unsolved problem. The simplest static black holes have mass but neither electric charge nor angular momentum. According to Birkhoff's theorem, these Schwarzschild black holes are the only vacuum solution that is spherically symmetric. Solutions describing more general black holes also exist. Non-rotating charged black holes are described by the Reissner–Nordström metric, while the Kerr metric describes a non-charged rotating black hole. The most general stationary black hole solution known is the Kerr–Newman metric, which describes a black hole with both charge and angular momentum. The simplest static black holes have mass but neither electric charge nor angular momentum. Contrary to the popular notion of a black hole "sucking in everything" in its surroundings, from far away, the external gravitational field of a black hole is identical to that of any other body of the same mass. While a black hole can theoretically have any positive mass, the charge and angular momentum are constrained by the mass. The total electric charge Q and the total angular momentum J are expected to satisfy the inequality Q 2 4 π ϵ 0 + c 2 J 2 G M 2 ≤ G M 2 {\displaystyle {\frac {Q^{2}}{4\pi \epsilon _{0}}}+{\frac {c^{2}J^{2}}{GM^{2}}}\leq GM^{2}} for a black hole of mass M. Black holes with the maximum possible charge or spin satisfying this inequality are called extremal black holes. Solutions of Einstein's equations that violate this inequality exist, but they do not possess an event horizon. These are so-called naked singularities that can be observed from the outside. Because these singularities make the universe inherently unpredictable, many physicists believe they could not exist. The weak cosmic censorship hypothesis, proposed by Sir Roger Penrose, rules out the formation of such singularities, when they are created through the gravitational collapse of realistic matter. However, this theory has not yet been proven, and some physicists believe that naked singularities could exist. It is also unknown whether black holes could even become extremal, forming naked singularities, since natural processes counteract increasing spin and charge when a black hole becomes near-extremal. The total mass of a black hole can be estimated by analyzing the motion of objects near the black hole, such as stars or gas. All black holes spin, often fast—One supermassive black hole, GRS 1915+105 has been estimated to spin at over 1,000 revolutions per second. The Milky Way's central black hole Sagittarius A* rotates at about 90% of the maximum rate. The spin rate can be inferred from measurements of atomic spectral lines in the X-ray range. As gas near the black hole plunges inward, high energy X-ray emission from electron-positron pairs illuminates the gas further out, appearing red-shifted due to relativistic effects. Depending on the spin of the black hole, this plunge happens at different radii from the hole, with different degrees of redshift. Astronomers can use the gap between the x-ray emission of the outer disk and the redshifted emission from plunging material to determine the spin of the black hole. A newer way to estimate spin is based on the temperature of gasses accreting onto the black hole. The method requires an independent measurement of the black hole mass and inclination angle of the accretion disk followed by computer modeling. Gravitational waves from coalescing binary black holes can also provide the spin of both progenitor black holes and the merged hole, but such events are rare. A spinning black hole has angular momentum. The supermassive black hole in the center of the Messier 87 (M87) galaxy appears to have an angular momentum very close to the maximum theoretical value. That uncharged limit is J ≤ G M 2 c , {\displaystyle J\leq {\frac {GM^{2}}{c}},} allowing definition of a dimensionless spin magnitude such that 0 ≤ c J G M 2 ≤ 1. {\displaystyle 0\leq {\frac {cJ}{GM^{2}}}\leq 1.} Most black holes are believed to have an approximately neutral charge. For example, Michal Zajaček, Arman Tursunov, Andreas Eckart, and Silke Britzen found the electric charge of Sagittarius A* to be at least ten orders of magnitude below the theoretical maximum. A charged black hole repels other like charges just like any other charged object. If a black hole were to become charged, particles with an opposite sign of charge would be pulled in by the extra electromagnetic force, while particles with the same sign of charge would be repelled, neutralizing the black hole. This effect may not be as strong if the black hole is also spinning. The presence of charge can reduce the diameter of the black hole by up to 38%. The charge Q for a nonspinning black hole is bounded by Q ≤ G M , {\displaystyle Q\leq {\sqrt {G}}M,} where G is the gravitational constant and M is the black hole's mass. Classification Black holes can have a wide range of masses. The minimum mass of a black hole formed by stellar gravitational collapse is governed by the maximum mass of a neutron star and is believed to be approximately two-to-four solar masses. However, theoretical primordial black holes, believed to have formed soon after the Big Bang, could be far smaller, with masses as little as 10−5 grams at formation. These very small black holes are sometimes called micro black holes. Black holes formed by stellar collapse are called stellar black holes. Estimates of their maximum mass at formation vary, but generally range from 10 to 100 solar masses, with higher estimates for black holes progenated by low-metallicity stars. The mass of a black hole formed via a supernova has a lower bound: If the progenitor star is too small, the collapse may be stopped by the degeneracy pressure of the star's constituents, allowing the condensation of matter into an exotic denser state. Degeneracy pressure occurs from the Pauli exclusion principle—Particles will resist being in the same place as each other. Smaller progenitor stars, with masses less than about 8 M☉, will be held together by the degeneracy pressure of electrons and will become a white dwarf. For more massive progenitor stars, electron degeneracy pressure is no longer strong enough to resist the force of gravity and the star will be held together by neutron degeneracy pressure, which can occur at much higher densities, forming a neutron star. If the star is still too massive, even neutron degeneracy pressure will not be able to resist the force of gravity and the star will collapse into a black hole.: 5.8 Stellar black holes can also gain mass via accretion of nearby matter, often from a companion object such as a star. Black holes that are larger than stellar black holes but smaller than supermassive black holes are called intermediate-mass black holes, with masses of approximately 102 to 105 solar masses. These black holes seem to be rarer than their stellar and supermassive counterparts, with relatively few candidates having been observed. Physicists have speculated that such black holes may form from collisions in globular and star clusters or at the center of low-mass galaxies. They may also form as the result of mergers of smaller black holes, with several LIGO observations finding merged black holes within the 110-350 solar mass range. The black holes with the largest masses are called supermassive black holes, with masses more than 106 times that of the Sun. These black holes are believed to exist at the centers of almost every large galaxy, including the Milky Way. Some scientists have proposed a subcategory of even larger black holes, called ultramassive black holes, with masses greater than 109-1010 solar masses. Theoretical models predict that the accretion disc that feeds black holes will be unstable once a black hole reaches 50-100 billion times the mass of the Sun, setting a rough upper limit to black hole mass. Structure While black holes are conceptually invisible sinks of all matter and light, in astronomical settings, their enormous gravity alters the motion of surrounding objects and pulls nearby gas inwards at near-light speed, making the area around black holes the brightest objects in the universe. Some black holes have relativistic jets—thin streams of plasma travelling away from the black hole at more than one-tenth of the speed of light. A small faction of the matter falling towards the black hole gets accelerated away along the hole rotation axis. These jets can extend as far as millions of parsecs from the black hole itself. Black holes of any mass can have jets. However, they are typically observed around spinning black holes with strongly-magnetized accretion disks. Relativistic jets were more common in the early universe, when galaxies and their corresponding supermassive black holes were rapidly gaining mass. All black holes with jets also have an accretion disk, but the jets are usually brighter than the disk. Quasars, typically found in other galaxies, are believed to be supermassive black holes with jets; microquasars are believed to be stellar-mass objects with jets, typically observed in the Milky Way. The mechanism of formation of jets is not yet known, but several options have been proposed. One method proposed to fuel these jets is the Blandford-Znajek process, which suggests that the dragging of magnetic field lines by a black hole's rotation could launch jets of matter into space. The Penrose process, which involves extraction of a black hole's rotational energy, has also been proposed as a potential mechanism of jet propulsion. Due to conservation of angular momentum, gas falling into the gravitational well created by a massive object will typically form a disk-like structure around the object.: 242 As the disk's angular momentum is transferred outward due to internal processes, its matter falls farther inward, converting its gravitational energy into heat and releasing a large flux of x-rays. The temperature of these disks can range from thousands to millions of Kelvin, and temperatures can differ throughout a single accretion disk. Accretion disks can also emit in other parts of the electromagnetic spectrum, depending on the disk's turbulence and magnetization and the black hole's mass and angular momentum. Accretion disks can be defined as geometrically thin or geometrically thick. Geometrically thin disks are mostly confined to the black hole's equatorial plane and have a well-defined edge at the innermost stable circular orbit (ISCO), while geometrically thick disks are supported by internal pressure and temperature and can extend inside the ISCO. Disks with high rates of electron scattering and absorption, appearing bright and opaque, are called optically thick; optically thin disks are more translucent and produce fainter images when viewed from afar. Accretion disks of black holes accreting beyond the Eddington limit are often referred to as polish donuts due to their thick, toroidal shape that resembles that of a donut. Quasar accretion disks are expected to usually appear blue in color. The disk for a stellar black hole, on the other hand, would likely look orange, yellow, or red, with its inner regions being the brightest. Theoretical research suggests that the hotter a disk is, the bluer it should be, although this is not always supported by observations of real astronomical objects. Accretion disk colors may also be altered by the Doppler effect, with the part of the disk travelling towards an observer appearing bluer and brighter and the part of the disk travelling away from the observer appearing redder and dimmer. In Newtonian gravity, test particles can stably orbit at arbitrary distances from a central object. In general relativity, however, there exists a smallest possible radius for which a massive particle can orbit stably. Any infinitesimal inward perturbations to this orbit will lead to the particle spiraling into the black hole, and any outward perturbations will, depending on the energy, cause the particle to spiral in, move to a stable orbit further from the black hole, or escape to infinity. This orbit is called the innermost stable circular orbit, or ISCO. The location of the ISCO depends on the spin of the black hole and the spin of the particle itself. In the case of a Schwarzschild black hole (spin zero) and a particle without spin, the location of the ISCO is: r I S C O = 3 r s = 6 G M c 2 , {\displaystyle r_{\rm {ISCO}}=3\,r_{\text{s}}={\frac {6\,GM}{c^{2}}},} where r I S C O {\displaystyle r_{\rm {_{ISCO}}}} is the radius of the ISCO, r s {\displaystyle r_{\text{s}}} is the Schwarzschild radius of the black hole, G {\displaystyle G} is the gravitational constant, and c {\displaystyle c} is the speed of light. The radius of this orbit changes slightly based on particle spin. For charged black holes, the ISCO moves inwards. For spinning black holes, the ISCO is moved inwards for particles orbiting in the same direction that the black hole is spinning (prograde) and outwards for particles orbiting in the opposite direction (retrograde). For example, the ISCO for a particle orbiting retrograde can be as far out as about 9 r s {\displaystyle 9r_{\text{s}}} , while the ISCO for a particle orbiting prograde can be as close as at the event horizon itself. The photon sphere is a spherical boundary for which photons moving on tangents to that sphere are bent completely around the black hole, possibly orbiting multiple times. Light rays with impact parameters less than the radius of the photon sphere enter the black hole. For Schwarzschild black holes, the photon sphere has a radius 1.5 times the Schwarzschild radius; the radius for non-Schwarzschild black holes is at least 1.5 times the radius of the event horizon. When viewed from a great distance, the photon sphere creates an observable black hole shadow. Since no light emerges from within the black hole, this shadow is the limit for possible observations.: 152 The shadow of colliding black holes should have characteristic warped shapes, allowing scientists to detect black holes that are about to merge. While light can still escape from the photon sphere, any light that crosses the photon sphere on an inbound trajectory will be captured by the black hole. Therefore, any light that reaches an outside observer from the photon sphere must have been emitted by objects between the photon sphere and the event horizon. Light emitted towards the photon sphere may also curve around the black hole and return to the emitter. For a rotating, uncharged black hole, the radius of the photon sphere depends on the spin parameter and whether the photon is orbiting prograde or retrograde. For a photon orbiting prograde, the photon sphere will be 1-3 Schwarzschild radii from the center of the black hole, while for a photon orbiting retrograde, the photon sphere will be between 3-5 Schwarzschild radii from the center of the black hole. The exact location of the photon sphere depends on the magnitude of the black hole's rotation. For a charged, nonrotating black hole, there will only be one photon sphere, and the radius of the photon sphere will decrease for increasing black hole charge. For non-extremal, charged, rotating black holes, there will always be two photon spheres, with the exact radii depending on the parameters of the black hole. Near a rotating black hole, spacetime rotates similar to a vortex. The rotating spacetime will drag any matter and light into rotation around the spinning black hole. This effect of general relativity, called frame dragging, gets stronger closer to the spinning mass. The region of spacetime in which it is impossible to stay still is called the ergosphere. The ergosphere of a black hole is a volume bounded by the black hole's event horizon and the ergosurface, which coincides with the event horizon at the poles but bulges out from it around the equator. Matter and radiation can escape from the ergosphere. Through the Penrose process, objects can emerge from the ergosphere with more energy than they entered with. The extra energy is taken from the rotational energy of the black hole, slowing down the rotation of the black hole.: 268 A variation of the Penrose process in the presence of strong magnetic fields, the Blandford–Znajek process, is considered a likely mechanism for the enormous luminosity and relativistic jets of quasars and other active galactic nuclei. The observable region of spacetime around a black hole closest to its event horizon is called the plunging region. In this area it is no longer possible for free falling matter to follow circular orbits or stop a final descent into the black hole. Instead, it will rapidly plunge toward the black hole at close to the speed of light, growing increasingly hot and producing a characteristic, detectable thermal emission. However, light and radiation emitted from this region can still escape from the black hole's gravitational pull. For a nonspinning, uncharged black hole, the radius of the event horizon, or Schwarzschild radius, is proportional to the mass, M, through r s = 2 G M c 2 ≈ 2.95 M M ⊙ k m , {\displaystyle r_{\mathrm {s} }={\frac {2GM}{c^{2}}}\approx 2.95\,{\frac {M}{M_{\odot }}}~\mathrm {km,} } where rs is the Schwarzschild radius and M☉ is the mass of the Sun.: 124 For a black hole with nonzero spin or electric charge, the radius is smaller,[Note 1] until an extremal black hole could have an event horizon close to r + = G M c 2 , {\displaystyle r_{\mathrm {+} }={\frac {GM}{c^{2}}},} half the radius of a nonspinning, uncharged black hole of the same mass. Since the volume within the Schwarzschild radius increase with the cube of the radius, average density of a black hole inside its Schwarzschild radius is inversely proportional to the square of its mass: supermassive black holes are much less dense than stellar black holes. The average density of a 108 M☉ black hole is comparable to that of water. The defining feature of a black hole is the existence of an event horizon, a boundary in spacetime through which matter and light can pass only inward towards the center of the black hole. Nothing, not even light, can escape from inside the event horizon. The event horizon is referred to as such because if an event occurs within the boundary, information from that event cannot reach or affect an outside observer, making it impossible to determine whether such an event occurred.: 179 For non-rotating black holes, the geometry of the event horizon is precisely spherical, while for rotating black holes, the event horizon is oblate. To a distant observer, a clock near a black hole would appear to tick more slowly than one further from the black hole.: 217 This effect, known as gravitational time dilation, would also cause an object falling into a black hole to appear to slow as it approached the event horizon, never quite reaching the horizon from the perspective of an outside observer.: 218 All processes on this object would appear to slow down, and any light emitted by the object to appear redder and dimmer, an effect known as gravitational redshift. An object falling from half of a Schwarzschild radius above the event horizon would fade away until it could no longer be seen, disappearing from view within one hundredth of a second. It would also appear to flatten onto the black hole, joining all other material that had ever fallen into the hole. On the other hand, an observer falling into a black hole would not notice any of these effects as they cross the event horizon. Their own clocks appear to them to tick normally, and they cross the event horizon after a finite time without noting any singular behaviour. In general relativity, it is impossible to determine the location of the event horizon from local observations, due to Einstein's equivalence principle.: 222 Black holes that are rotating and/or charged have an inner horizon, often called the Cauchy horizon, inside of the black hole. The inner horizon is divided up into two segments: an ingoing section and an outgoing section. At the ingoing section of the Cauchy horizon, radiation and matter that fall into the black hole would build up at the horizon, causing the curvature of spacetime to go to infinity. This would cause an observer falling in to experience tidal forces. This phenomenon is often called mass inflation, since it is associated with a parameter dictating the black hole's internal mass growing exponentially, and the buildup of tidal forces is called the mass-inflation singularity or Cauchy horizon singularity. Some physicists have argued that in realistic black holes, accretion and Hawking radiation would stop mass inflation from occurring. At the outgoing section of the inner horizon, infalling radiation would backscatter off of the black hole's spacetime curvature and travel outward, building up at the outgoing Cauchy horizon. This would cause an infalling observer to experience a gravitational shock wave and tidal forces as the spacetime curvature at the horizon grew to infinity. This buildup of tidal forces is called the shock singularity. Both of these singularities are weak, meaning that an object crossing them would only be deformed a finite amount by tidal forces, even though the spacetime curvature would still be infinite at the singularity. This is as opposed to a strong singularity, where an object hitting the singularity would be stretched and squeezed by an infinite amount. They are also null singularities, meaning that a photon could travel parallel to the them without ever being intercepted. Ignoring quantum effects, every black hole has a singularity inside, points where the curvature of spacetime becomes infinite, and geodesics terminate within a finite proper time.: 205 For a non-rotating black hole, this region takes the shape of a single point; for a rotating black hole it is smeared out to form a ring singularity that lies in the plane of rotation.: 264 In both cases, the singular region has zero volume. All of the mass of the black hole ends up in the singularity.: 252 Since the singularity has nonzero mass in an infinitely small space, it can be thought of as having infinite density. Observers falling into a Schwarzschild black hole (i.e., non-rotating and not charged) cannot avoid being carried into the singularity once they cross the event horizon. As they fall further into the black hole, they will be torn apart by the growing tidal forces in a process sometimes referred to as spaghettification or the noodle effect. Eventually, they will reach the singularity and be crushed into an infinitely small point.: 182 However any perturbations, such as those caused by matter or radiation falling in, would cause space to oscillate chaotically near the singularity. Any matter falling in would experience intense tidal forces rapidly changing in direction, all while being compressed into an increasingly small volume. Alternative forms of general relativity, including addition of some quatum effects, can lead to regular, or nonsingular, black holes without singularities. For example, the fuzzball model, based on string theory, states that black holes are actually made up of quantum microstates and need not have a singularity or an event horizon. The theory of loop quantum gravity proposes that the curvature and density at the center of a black hole is large, but not infinite. Formation Black holes are formed by gravitational collapse of massive stars, either by direct collapse or during a supernova explosion in a process called fallback. Black holes can result from the merger of two neutron stars or a neutron star and a black hole. Other more speculative mechanisms include primordial black holes created from density fluctuations in the early universe, the collapse of dark stars, a hypothetical object powered by annihilation of dark matter, or from hypothetical self-interacting dark matter. Gravitational collapse occurs when an object's internal pressure is insufficient to resist the object's own gravity. At the end of a star's life, it will run out of hydrogen to fuse, and will start fusing more and more massive elements, until it gets to iron. Since the fusion of elements heavier than iron would require more energy than it would release, nuclear fusion ceases. If the iron core of the star is too massive, the star will no longer be able to support itself and will undergo gravitational collapse. While most of the energy released during gravitational collapse is emitted very quickly, an outside observer does not actually see the end of this process. Even though the collapse takes a finite amount of time from the reference frame of infalling matter, a distant observer would see the infalling material slow and halt just above the event horizon, due to gravitational time dilation. Light from the collapsing material takes longer and longer to reach the observer, with the delay growing to infinity as the emitting material reaches the event horizon. Thus the external observer never sees the formation of the event horizon; instead, the collapsing material seems to become dimmer and increasingly red-shifted, eventually fading away. Observations of quasars at redshift z ∼ 7 {\displaystyle z\sim 7} , less than a billion years after the Big Bang, has led to investigations of other ways to form black holes. The accretion process to build supermassive black holes has a limiting rate of mass accumulation and a billion years is not enough time to reach quasar status. One suggestion is direct collapse of nearly pure hydrogen gas (low metalicity) clouds characteristic of the young universe, forming a supermassive star which collapses into a black hole. It has been suggested that seed black holes with typical masses of ~105 M☉ could have formed in this way which then could grow to ~109 M☉. However, the very large amount of gas required for direct collapse is not typically stable to fragmentation to form multiple stars. Thus another approach suggests massive star formation followed by collisions that seed massive black holes which ultimately merge to create a quasar.: 85 A neutron star in a common envelope with a regular star can accrete sufficient material to collapse to a black hole or two neutron stars can merge. These avenues for the formation of black holes are considered relatively rare. In the current epoch of the universe, conditions needed to form black holes are rare and are mostly only found in stars. However, in the early universe, conditions may have allowed for black hole formations via other means. Fluctuations of spacetime soon after the Big Bang may have formed areas that were denser then their surroundings. Initially, these regions would not have been compact enough to form a black hole, but eventually, the curvature of spacetime in the regions become large enough to cause them to collapse into a black hole. Different models for the early universe vary widely in their predictions of the scale of these fluctuations. Various models predict the creation of primordial black holes ranging from a Planck mass (~2.2×10−8 kg) to hundreds of thousands of solar masses. Primordial black holes with masses less than 1015 g would have evaporated by now due to Hawking radiation. Despite the early universe being extremely dense, it did not re-collapse into a black hole during the Big Bang, since the universe was expanding rapidly and did not have the gravitational differential necessary for black hole formation. Models for the gravitational collapse of objects of relatively constant size, such as stars, do not necessarily apply in the same way to rapidly expanding space such as the Big Bang. In principle, black holes could be formed in high-energy particle collisions that achieve sufficient density, although no such events have been detected. These hypothetical micro black holes, which could form from the collision of cosmic rays and Earth's atmosphere or in particle accelerators like the Large Hadron Collider, would not be able to aggregate additional mass. Instead, they would evaporate in about 10−25 seconds, posing no threat to the Earth. Evolution Black holes can also merge with other objects such as stars or even other black holes. This is thought to have been important, especially in the early growth of supermassive black holes, which could have formed from the aggregation of many smaller objects. The process has also been proposed as the origin of some intermediate-mass black holes. Mergers of supermassive black holes may take a long time: As a binary of supermassive black holes approach each other, most nearby stars are ejected, leaving little for the remaining black holes to gravitationally interact with that would allow them to get closer to each other. This phenomenon has been called the final parsec problem, as the distance at which this happens is usually around one parsec. When a black hole accretes matter, the gas in the inner accretion disk orbits at very high speeds because of its proximity to the black hole. The resulting friction heats the inner disk to temperatures at which it emits vast amounts of electromagnetic radiation (mainly X-rays) detectable by telescopes. By the time the matter of the disk reaches the ISCO, between 5.7% and 42% of its mass will have been converted to energy, depending on the black hole's spin. About 90% of this energy is released within about 20 black hole radii. In many cases, accretion disks are accompanied by relativistic jets that are emitted along the black hole's poles, which carry away much of the energy. The mechanism for the creation of these jets is currently not well understood, in part due to insufficient data. Many of the universe's most energetic phenomena have been attributed to the accretion of matter on black holes. Active galactic nuclei and quasars are believed to be the accretion disks of supermassive black holes. X-ray binaries are generally accepted to be binary systems in which one of the two objects is a compact object accreting matter from its companion. Ultraluminous X-ray sources may be the accretion disks of intermediate-mass black holes. At a certain rate of accretion, the outward radiation pressure will become as strong as the inward gravitational force, and the black hole should unable to accrete any faster. This limit is called the Eddington limit. However, many black holes accrete beyond this rate due to their non-spherical geometry or instabilities in the accretion disk. Accretion beyond the limit is called Super-Eddington accretion and may have been commonplace in the early universe. Stars have been observed to get torn apart by tidal forces in the immediate vicinity of supermassive black holes in galaxy nuclei, in what is known as a tidal disruption event (TDE). Some of the material from the disrupted star forms an accretion disk around the black hole, which emits observable electromagnetic radiation. The correlation between the masses of supermassive black holes in the centres of galaxies with the velocity dispersion and mass of stars in their host bulges suggests that the formation of galaxies and the formation of their central black holes are related. Black hole winds from rapid accretion, particularly when the galaxy itself is still accreting matter, can compress gas nearby, accelerating star formation. However, if the winds become too strong, the black hole may blow nearly all of the gas out of the galaxy, quenching star formation. Black hole jets may also energize nearby cavities of plasma and eject low-entropy gas from out of the galactic core, causing gas in galactic centers to be hotter than expected. If Hawking's theory of black hole radiation is correct, then black holes are expected to shrink and evaporate over time as they lose mass by the emission of photons and other particles. The temperature of this thermal spectrum (Hawking temperature) is proportional to the surface gravity of the black hole, which is inversely proportional to the mass. Hence, large black holes emit less radiation than small black holes.: Ch. 9.6 A stellar black hole of 1 M☉ has a Hawking temperature of 62 nanokelvins. This is far less than the 2.7 K temperature of the cosmic microwave background radiation. Stellar-mass or larger black holes receive more mass from the cosmic microwave background than they emit through Hawking radiation and thus will grow instead of shrinking. To have a Hawking temperature larger than 2.7 K (and be able to evaporate), a black hole would need a mass less than the Moon. Such a black hole would have a diameter of less than a tenth of a millimetre. The Hawking radiation for an astrophysical black hole is predicted to be very weak and would thus be exceedingly difficult to detect from Earth. A possible exception is the burst of gamma rays emitted in the last stage of the evaporation of primordial black holes. Searches for such flashes have proven unsuccessful and provide stringent limits on the possibility of existence of low mass primordial black holes, with modern research predicting that primordial black holes must make up less than a fraction of 10−7 of the universe's total mass. NASA's Fermi Gamma-ray Space Telescope, launched in 2008, has searched for these flashes, but has not yet found any. The properties of a black hole are constrained and interrelated by the theories that predict these properties. When based on general relativity, these relationships are called the laws of black hole mechanics. For a black hole that is not still forming or accreting matter, the zeroth law of black hole mechanics states the black hole's surface gravity is constant across the event horizon. The first law relates changes in the black hole's surface area, angular momentum, and charge to changes in its energy. The second law says the surface area of a black hole never decreases on its own. Finally, the third law says that the surface gravity of a black hole is never zero. These laws are mathematical analogs of the laws of thermodynamics. They are not equivalent, however, because, according to general relativity without quantum mechanics, a black hole can never emit radiation, and thus its temperature must always be zero.: 11 Quantum mechanics predicts that a black hole will continuously emit thermal Hawking radiation, and therefore must always have a nonzero temperature. It also predicts that all black holes have entropy which scales with their surface area. When quantum mechanics is accounted for, the laws of black hole mechanics become equivalent to the classical laws of thermodynamics. However, these conclusions are derived without a complete theory of quantum gravity, although many potential theories do predict black holes having entropy and temperature. Thus, the true quantum nature of black hole thermodynamics continues to be debated.: 29 Observational evidence Millions of black holes with around 30 solar masses derived from stellar collapse are expected to exist in the Milky Way. Even a dwarf galaxy like Draco should have hundreds. Only a few of these have been detected. By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists searching for black holes must generally rely on indirect observations. The defining characteristic of a black hole is its event horizon. The horizon itself cannot be imaged, so all other possible explanations for these indirect observations must be considered and eliminated before concluding that a black hole has been observed.: 11 The Event Horizon Telescope (EHT) is a global system of radio telescopes capable of directly observing a black hole shadow. The angular resolution of a telescope is based on its aperture and the wavelengths it is observing. Because the angular diameters of Sagittarius A* and Messier 87* in the sky are very small, a single telescope would need to be about the size of the Earth to clearly distinguish their horizons using radio wavelengths. By combining data from several different radio telescopes around the world, the Event Horizon Telescope creates an effective aperture the diameter size of the Earth. The EHT team used imaging algorithms to compute the most probable image from the data in its observations of Sagittarius A* and M87*. Gravitational-wave interferometry can be used to detect merging black holes and other compact objects. In this method, a laser beam is split down two long arms of a tunnel. The laser beams reflect off of mirrors in the tunnels and converge at the intersection of the arms, cancelling each other out. However, when a gravitational wave passes, it warps spacetime, changing the lengths of the arms themselves. Since each laser beam is now travelling a slightly different distance, they do not cancel out and produce a recognizable signal. Analysis of the signal can give scientists information about what caused the gravitational waves. Since gravitational waves are very weak, gravitational-wave observatories such as LIGO must have arms several kilometers long and carefully control for noise from Earth to be able to detect these gravitational waves. Since the first measurements in 2016, multiple gravitational waves from black holes have been detected and analyzed. The proper motions of stars near the centre of the Milky Way provide strong observational evidence that these stars are orbiting a supermassive black hole. Since 1995, astronomers have tracked the motions of 90 stars orbiting an invisible object coincident with the radio source Sagittarius A*. In 1998, by fitting the motions of the stars to Keplerian orbits, the astronomers were able to infer that Sagittarius A* must be a 2.6×106 M☉ object must be contained within a radius of 0.02 light-years. Since then, one of the stars—called S2—has completed a full orbit. From the orbital data, astronomers were able to refine the calculations of the mass of Sagittarius A* to 4.3×106 M☉, with a radius of less than 0.002 light-years. This upper limit radius is larger than the Schwarzschild radius for the estimated mass, so the combination does not prove Sagittarius A* is a black hole. Nevertheless, these observations strongly suggest that the central object is a supermassive black hole as there are no other plausible scenarios for confining so much invisible mass into such a small volume. Additionally, there is some observational evidence that this object might possess an event horizon, a feature unique to black holes. The Event Horizon Telescope image of Sagittarius A*, released in 2022, provided further confirmation that it is indeed a black hole. X-ray binaries are binary systems that emit a majority of their radiation in the X-ray part of the electromagnetic spectrum. These X-ray emissions result when a compact object accretes matter from an ordinary star. The presence of an ordinary star in such a system provides an opportunity for studying the central object and to determine if it might be a black hole. By measuring the orbital period of the binary, the distance to the binary from Earth, and the mass of the companion star, scientists can estimate the mass of the compact object. The Tolman-Oppenheimer-Volkoff limit (TOV limit) dictates the largest mass a nonrotating neutron star can be, and is estimated to be about two solar masses. While a rotating neutron star can be slightly more massive, if the compact object is much more massive than the TOV limit, it cannot be a neutron star and is generally expected to be a black hole. The first strong candidate for a black hole, Cygnus X-1, was discovered in this way by Charles Thomas Bolton, Louise Webster, and Paul Murdin in 1972. Observations of rotation broadening of the optical star reported in 1986 lead to a compact object mass estimate of 16 solar masses, with 7 solar masses as the lower bound. In 2011, this estimate was updated to 14.1±1.0 M☉ for the black hole and 19.2±1.9 M☉ for the optical stellar companion. X-ray binaries can be categorized as either low-mass or high-mass; This classification is based on the mass of the companion star, not the compact object itself. In a class of X-ray binaries called soft X-ray transients, the companion star is of relatively low mass, allowing for more accurate estimates of the black hole mass. These systems actively emit X-rays for only several months once every 10–50 years. During the period of low X-ray emission, called quiescence, the accretion disk is extremely faint, allowing detailed observation of the companion star. Numerous black hole candidates have been measured by this method. Black holes are also sometimes found in binaries with other compact objects, such as white dwarfs, neutron stars, and other black holes. The centre of nearly every galaxy contains a supermassive black hole. The close observational correlation between the mass of this hole and the velocity dispersion of the host galaxy's bulge, known as the M–sigma relation, strongly suggests a connection between the formation of the black hole and that of the galaxy itself. Astronomers use the term active galaxy to describe galaxies with unusual characteristics, such as unusual spectral line emission and very strong radio emission. Theoretical and observational studies have shown that the high levels of activity in the centers of these galaxies, regions called active galactic nuclei (AGN), may be explained by accretion onto supermassive black holes. These AGN consist of a central black hole that may be millions or billions of times more massive than the Sun, a disk of interstellar gas and dust called an accretion disk, and two jets perpendicular to the accretion disk. Although supermassive black holes are expected to be found in most AGN, only some galaxies' nuclei have been more carefully studied in attempts to both identify and measure the actual masses of the central supermassive black hole candidates. Some of the most notable galaxies with supermassive black hole candidates include the Andromeda Galaxy, Messier 32, Messier 87, the Sombrero Galaxy, and the Milky Way itself. Another way black holes can be detected is through observation of effects caused by their strong gravitational field. One such effect is gravitational lensing: The deformation of spacetime around a massive object causes light rays to be deflected, making objects behind them appear distorted. When the lensing object is a black hole, this effect can be strong enough to create multiple images of a star or other luminous source. However, the distance between the lensed images may be too small for contemporary telescopes to resolve—this phenomenon is called microlensing. Instead of seeing two images of a lensed star, astronomers see the star brighten slightly as the black hole moves towards the line of sight between the star and Earth and then return to its normal luminosity as the black hole moves away. The turn of the millennium saw the first 3 candidate detections of black holes in this way, and in January 2022, astronomers reported the first confirmed detection of a microlensing event from an isolated black hole. This was also the first determination of an isolated black hole mass, 7.1±1.3 M☉. Alternatives While there is a strong case for supermassive black holes, the model for stellar-mass black holes assumes of an upper limit for the mass of a neutron star: objects observed to have more mass are assumed to be black holes. However, the properties of extremely dense matter are poorly understood. New exotic phases of matter could allow other kinds of massive objects. Quark stars would be made up of quark matter and supported by quark degeneracy pressure, a form of degeneracy pressure even stronger than neutron degeneracy pressure. This would halt gravitational collapse at a higher mass than for a neutron star. Even stronger stars called electroweak stars would convert quarks in their cores into leptons, providing additional pressure to stop the star from collapsing. If, as some extensions of the Standard Model posit, quarks and leptons are made up of the even-smaller fundamental particles called preons, a very compact star could be supported by preon degeneracy pressure. While none of these hypothetical models can explain all of the observations of stellar black hole candidates, a Q star is the only alternative which could significantly exceed the mass limit for neutron stars and thus provide an alternative for supermassive black holes.: 12 A few theoretical objects have been conjectured to match observations of astronomical black hole candidates identically or near-identically, but which function via a different mechanism. A dark energy star would convert infalling matter into vacuum energy; This vacuum energy would be much larger than the vacuum energy of outside space, exerting outwards pressure and preventing a singularity from forming. A black star would be gravitationally collapsing slowly enough that quantum effects would keep it just on the cusp of fully collapsing into a black hole. A gravastar would consist of a very thin shell and a dark-energy interior providing outward pressure to stop the collapse into a black hole or formation of a singularity; It could even have another gravastar inside, called a 'nestar'. Open questions According to the no-hair theorem, a black hole is defined by only three parameters: its mass, charge, and angular momentum. This seems to mean that all other information about the matter that went into forming the black hole is lost, as there is no way to determine anything about the black hole from outside other than those three parameters. When black holes were thought to persist forever, this information loss was not problematic, as the information can be thought of as existing inside the black hole. However, black holes slowly evaporate by emitting Hawking radiation. This radiation does not appear to carry any additional information about the matter that formed the black hole, meaning that this information is seemingly gone forever. This is called the black hole information paradox. Theoretical studies analyzing the paradox have led to both further paradoxes and new ideas about the intersection of quantum mechanics and general relativity. While there is no consensus on the resolution of the paradox, work on the problem is expected to be important for a theory of quantum gravity.: 126 Observations of faraway galaxies have found that ultraluminous quasars, powered by supermassive black holes, existed in the early universe as far as redshift z ≥ 7 {\displaystyle z\geq 7} . These black holes have been assumed to be the products of the gravitational collapse of large population III stars. However, these stellar remnants were not massive enough to produce the quasars observed at early times without accreting beyond the Eddington limit, the theoretical maximum rate of black hole accretion. Physicists have suggested a variety of different mechanisms by which these supermassive black holes may have formed. It has been proposed that smaller black holes may have also undergone mergers to produce the observed supermassive black holes. It is also possible that they were seeded by direct-collapse black holes, in which a large cloud of hot gas avoids fragmentation that would lead to multiple stars, due to low angular momentum or heating from a nearby galaxy. Given the right circumstances, a single supermassive star forms and collapses directly into a black hole without undergoing typical stellar evolution. Additionally, these supermassive black holes in the early universe may be high-mass primordial black holes, which could have accreted further matter in the centers of galaxies. Finally, certain mechanisms allow black holes to grow faster than the theoretical Eddington limit, such as dense gas in the accretion disk limiting outward radiation pressure that prevents the black hole from accreting. However, the formation of bipolar jets prevent super-Eddington rates. In fiction Black holes have been portrayed in science fiction in a variety of ways. Even before the advent of the term itself, objects with characteristics of black holes appeared in stories such as the 1928 novel The Skylark of Space with its "black Sun" and the "hole in space" in the 1935 short story Starship Invincible. As black holes grew to public recognition in the 1960s and 1970s, they began to be featured in films as well as novels, such as Disney's The Black Hole. Black holes have also been used in works of the 21st century, such as Christopher Nolan's science fiction epic Interstellar. Authors and screenwriters have exploited the relativistic effects of black holes, particularly gravitational time dilation. For example, Interstellar features a black hole planet with a time dilation factor of over 60,000:1, while the 1977 novel Gateway depicts a spaceship approaching but never crossing the event horizon of a black hole from the perspective of an outside observer due to time dilation effects. Black holes have also been appropriated as wormholes or other methods of faster-than-light travel, such as in the 1974 novel The Forever War, where a network of black holes is used for interstellar travel. Additionally, black holes can feature as hazards to spacefarers and planets: A black hole threatens a deep-space outpost in 1978 short story The Black Hole Passes, and a binary black hole dangerously alters the orbit of a planet in the 2018 Netflix reboot of Lost in Space.

Contents Extraterrestrial life Extraterrestrial life, or alien life (colloquially aliens), is life that originates from another world rather than on Earth. No extraterrestrial life has yet been scientifically or conclusively detected. Such life might range from simple forms such as prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more, or far less, advanced than humans. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life is known as astrobiology. Speculation about inhabited worlds beyond Earth dates back to antiquity. Early Christian writers, including Augustine, discussed ideas from thinkers like Democritus and Epicurus about countless worlds in the vast universe. Pre-modern writers typically assumed extraterrestrial "worlds" were inhabited by living beings. William Vorilong, in the 15th century, acknowledged the possibility Jesus could have visited extraterrestrial worlds to redeem their inhabitants.: 26 In 1440, Nicholas of Cusa suggested Earth is a "brilliant star"; he theorized that all celestial bodies, even the Sun, could host life. Descartes wrote that there were no means to prove the stars were not inhabited by "intelligent creatures", but their existence was a matter of speculation.: 67 In comparison to the life-abundant Earth, the vast majority of intrasolar and extrasolar planets and moons have harsh surface conditions and disparate atmospheric chemistry, or lack an atmosphere. However, there are many extreme and chemically harsh ecosystems on Earth that do support forms of life and are often hypothesized to be the origin of life on Earth. Examples include life surrounding hydrothermal vents, acidic hot springs, and volcanic lakes, as well as halophiles and the deep biosphere. Since the mid-20th century, researchers have searched for extraterrestrial life and intelligence. Solar system studies focus on Venus, Mars, Europa, and Titan, while exoplanet discoveries now total 6,022 confirmed planets in 4,490 systems as of October 2025. Depending on the category of search, methods range from analysis of telescope and specimen data to radios used to detect and transmit interstellar communication. Interstellar travel remains largely hypothetical, with only the Voyager 1 and Voyager 2 probes confirmed to have entered the interstellar medium. The concept of extraterrestrial life, especially intelligent life, has greatly influenced culture and fiction. A key debate centers on contacting extraterrestrial intelligence: some advocate active attempts, while others warn it could be risky, given human history of exploiting other societies. Context Initially, after the Big Bang, the universe was too hot to allow life. It is estimated that the temperature of the universe was around 10 billion Kelvin at the one-second mark. Roughly 15 million years later, it cooled to temperate levels, though the elements of organic life were yet nonexistent. The only freely available elements at that point were hydrogen and helium. Carbon and oxygen (and later, water) would not appear until 50 million years later, created through stellar fusion. At that point, the difficulty for life to appear was not the temperature, but the scarcity of free heavy elements. Planetary systems emerged, and the first organic compounds may have formed in the protoplanetary disk of dust grains that would eventually create rocky planets like Earth. Although Earth was in a molten state after its birth and may have burned any organics that fell on it, it would have been more receptive once it cooled down. Once the right conditions on Earth were met, life started by a chemical process known as abiogenesis. Alternatively, life may have formed less frequently, then spread—by meteoroids, for example—between habitable planets in a process called panspermia. During most of its stellar evolution, stars combine hydrogen nuclei to make helium nuclei by stellar fusion, and the comparatively lighter weight of helium allows the star to release the extra energy. The process continues until the star uses all of its available fuel, with the speed of consumption being related to the size of the star. During its last stages, stars start combining helium nuclei to form carbon nuclei. The larger stars can further combine carbon nuclei to create oxygen and silicon, oxygen into neon and sulfur, and so on until iron. Ultimately, the star blows much of its content back into the stellar medium, where it would join clouds that would eventually become new generations of stars and planets. Many of those materials are the raw components of life on Earth. As this process takes place in all the universe, said materials are ubiquitous in the cosmos and not a rarity from the Solar System. Earth is a planet in the Solar System, a planetary system formed by a star at the center, the Sun, and the objects that orbit it: other planets, moons, asteroids, and comets. The sun is part of the Milky Way, a galaxy. The Milky Way is part of the Local Group, a galaxy group that is in turn part of the Laniakea Supercluster. The universe is composed of all similar structures in existence. The immense distances between celestial objects are a difficulty for studying extraterrestrial life. So far, humans have only set foot on the Moon and sent robotic probes to other planets and moons in the Solar System. Although probes can withstand conditions that may be lethal to humans, the distances cause time delays: the New Horizons took nine years after launch to reach Pluto. No probe has ever reached extrasolar planetary systems. The Voyager 2 left the Solar System at a speed of 50,000 kilometers per hour; if it headed towards the Alpha Centauri system, the closest one to Earth at 4.4 light years, it would reach it in 100,000 years. Under current technology, such systems can only be studied by telescopes, which have limitations. It is estimated that dark matter has a larger amount of combined matter than stars and gas clouds, but as it plays no role in the stellar evolution of stars and planets, it is usually not taken into account by astrobiology. There is an area around a star, the circumstellar habitable zone or "Goldilocks zone", wherein water may be at the right temperature to exist in liquid form at a planetary surface. This area is neither too close to the star, where water would become steam, nor too far away, where water would be frozen as ice. However, although useful as an approximation, planetary habitability is complex and defined by several factors. Being in the habitable zone is not enough for a planet to be habitable, not even to actually have such liquid water. Venus is located in the solar system's habitable zone, but does not have liquid water because of the conditions of its atmosphere. Jovian planets or gas giants are not considered habitable even if they orbit close enough to their stars as hot Jupiters, due to crushing atmospheric pressures. The actual distances for the habitable zones vary according to the type of star, and even the solar activity of each specific star influences the local habitability. The type of star also defines the time the habitable zone will exist, as its presence and limits will change along with the star's stellar evolution. The Big Bang occurred 13.8 billion years ago, the Solar System was formed 4.6 billion years ago, and the first hominids appeared 6 million years ago. Life on other planets may have started, evolved, given birth to extraterrestrial intelligences, and perhaps even faced a planetary extinction event millions or billions of years ago. When considered from a cosmic perspective, the brief times of existence of Earth's species may suggest that extraterrestrial life may be equally fleeting under such a scale. During a period of about 7 million years, from about 10 to 17 million years after the Big Bang, the background temperature was between 373 and 273 K (100 and 0 °C; 212 and 32 °F), allowing the possibility of liquid water if any planets existed. Avi Loeb (2014) speculated that primitive life might in principle have appeared during this window, which he called "the Habitable Epoch of the Early Universe". Life on Earth is quite ubiquitous across the planet and has adapted over time to almost all the available environments in it, extremophiles and the deep biosphere thrive at even the most hostile ones. As a result, it is inferred that life in other celestial bodies may be equally adaptive. However, the origin of life is unrelated to its ease of adaptation and may have stricter requirements. A celestial body may not have any life on it, even if it were habitable. Likelihood of existence Life in the cosmos beyond Earth has been observed. The hypothesis of ubiquitous extraterrestrial life relies on three main ideas. The first one, the size of the universe, allows for plenty of planets to have a similar habitability to Earth, and the age of the universe gives enough time for a long process analog to the history of Earth to happen there. The second is that the substances that make life, such as carbon and water, are ubiquitous in the universe. The third is that the physical laws are universal, which means that the forces that would facilitate or prevent the existence of life would be the same ones as on Earth. According to this argument, made by scientists such as Carl Sagan and Stephen Hawking, it would be improbable for life not to exist somewhere else other than Earth. This argument is embodied in the Copernican principle, which states that Earth does not occupy a unique position in the Universe, and the mediocrity principle, which states that there is nothing special about life on Earth. Other authors consider instead that life in the cosmos, or at least multicellular life, may actually be rare. The Rare Earth hypothesis maintains that life on Earth is possible because of a series of factors that range from the location in the galaxy and the configuration of the Solar System to local characteristics of the planet, and that it is unlikely that another planet simultaneously meets all such requirements. The proponents of this hypothesis consider that very little evidence suggests the existence of extraterrestrial life and that, at this point, it is just a desired result and not a reasonable scientific explanation for any gathered data. In 1961, astronomer and astrophysicist Frank Drake devised the Drake equation as a way to stimulate scientific dialogue at a meeting on the search for extraterrestrial intelligence (SETI). The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. The Drake equation is:: xix where: and Drake's proposed estimates are as follows, but numbers on the right side of the equation are agreed as speculative and open to substitution: 10,000 = 5 ⋅ 0.5 ⋅ 2 ⋅ 1 ⋅ 0.2 ⋅ 1 ⋅ 10,000 {\displaystyle 10{,}000=5\cdot 0.5\cdot 2\cdot 1\cdot 0.2\cdot 1\cdot 10{,}000} [better source needed] The Drake equation has proved controversial since, although it is written as a math equation, none of its values were known at the time. Although some values may eventually be measured, others are based on social sciences and are not knowable by their very nature. This does not allow one to make noteworthy conclusions from the equation. Based on observations from the Hubble Space Telescope, there are nearly 2 trillion galaxies in the observable universe. It is estimated that at least ten percent of all Sun-like stars have a system of planets. In other words, there are 6.25×1018 stars with planets orbiting them in the observable universe. Even if it is assumed that only one out of a billion of these stars has planets supporting life, there would be some 6.25 billion life-supporting planetary systems in the observable universe. A 2013 study based on results from the Kepler spacecraft estimated that the Milky Way contains at least as many planets as it does stars, resulting in 100–400 billion exoplanets. The Nebular hypothesis that explains the formation of the Solar System and other planetary systems would suggest that those can have several configurations, and not all of them may have rocky planets within the habitable zone. The apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilisations and the lack of evidence for such civilisations is known as the Fermi paradox. Dennis W. Sciama claimed that life's existence in the universe depends on various fundamental constants. Zhi-Wei Wang and Samuel L. Braunstein suggest that a random universe capable of supporting life is likely to be just barely able to do so, giving a potential explanation to the Fermi paradox. Biochemical basis If extraterrestrial life exists, it could range from simple microorganisms and multicellular organisms similar to animals or plants, to complex alien intelligences akin to humans. When scientists talk about extraterrestrial life, they consider all those types. Although it is possible that extraterrestrial life may have other configurations, scientists use the hierarchy of lifeforms from Earth for simplicity, as it is the only one known to exist. The first basic requirement for life is an environment with non-equilibrium thermodynamics, which means that the thermodynamic equilibrium must be broken by a source of energy. The traditional sources of energy in the cosmos are the stars, such as for life on Earth, which depends on the energy of the sun. However, there are other alternative energy sources, such as volcanoes, plate tectonics, and hydrothermal vents. There are ecosystems on Earth in deep areas of the ocean that do not receive sunlight, and take energy from black smokers instead. Magnetic fields and radioactivity have also been proposed as sources of energy, although they would be less efficient ones. Life on Earth requires water in a liquid state as a solvent in which biochemical reactions take place. It is highly unlikely that an abiogenesis process can start within a gaseous or solid medium: the atom speeds, either too fast or too slow, make it difficult for specific ones to meet and start chemical reactions. A liquid medium also allows the transport of nutrients and substances required for metabolism. Sufficient quantities of carbon and other elements, along with water, might enable the formation of living organisms on terrestrial planets with a chemical make-up and temperature range similar to that of Earth. Life based on ammonia rather than water has been suggested as an alternative, though this solvent appears less suitable than water. It is also conceivable that there are forms of life whose solvent is a liquid hydrocarbon, such as methane, ethane or propane. Another unknown aspect of potential extraterrestrial life would be the chemical elements that would compose it. Life on Earth is largely composed of carbon, but there could be other hypothetical types of biochemistry. A replacement for carbon would need to be able to create complex molecules, store information required for evolution, and be freely available in the medium. To create DNA, RNA, or a close analog, such an element should be able to bind its atoms with many others, creating complex and stable molecules. It should be able to create at least three covalent bonds: two for making long strings and at least a third to add new links and allow for diverse information. Only nine elements meet this requirement: boron, nitrogen, phosphorus, arsenic, antimony (three bonds), carbon, silicon, germanium and tin (four bonds). As for abundance, carbon, nitrogen, and silicon are the most abundant ones in the universe, far more than the others. On Earth's crust the most abundant of those elements is silicon, in the Hydrosphere it is carbon and in the atmosphere, it is carbon and nitrogen. Silicon, however, has disadvantages over carbon. The molecules formed with silicon atoms are less stable, and more vulnerable to acids, oxygen, and light. An ecosystem of silicon-based lifeforms would require very low temperatures, high atmospheric pressure, an atmosphere devoid of oxygen, and a solvent other than water. The low temperatures required would add an extra problem, the difficulty to kickstart a process of abiogenesis to create life in the first place. Norman Horowitz, head of the Jet Propulsion Laboratory bioscience section for the Mariner and Viking missions from 1965 to 1976 considered that the great versatility of the carbon atom makes it the element most likely to provide solutions, even exotic solutions, to the problems of survival of life on other planets. However, he also considered that the conditions found on Mars were incompatible with carbon based life. Even if extraterrestrial life is based on carbon and uses water as a solvent, like Earth life, it may still have a radically different biochemistry. Life is generally considered to be a product of natural selection. It has been proposed that to undergo natural selection a living entity must have the capacity to replicate itself, the capacity to avoid damage/decay, and the capacity to acquire and process resources in support of the first two capacities. Life on Earth may have started with an RNA world and later evolved to its current form, where some of the RNA tasks were transferred to DNA and proteins. Extraterrestrial life may still be stuck using RNA, or evolve into other configurations. It is unclear if our biochemistry is the most efficient one that could be generated, or which elements would follow a similar pattern. However, it is likely that, even if cells had a different composition to those from Earth, they would still have a cell membrane. Life on Earth jumped from prokaryotes to eukaryotes and from unicellular organisms to multicellular organisms through evolution. So far no alternative process to achieve such a result has been conceived, even if hypothetical. Evolution requires life to be divided into individual organisms, and no alternative organisation has been satisfactorily proposed either. At the basic level, membranes define the limit of a cell, between it and its environment, while remaining partially open to exchange energy and resources with it. The evolution from simple cells to eukaryotes, and from them to multicellular lifeforms, is not guaranteed. The Cambrian explosion took place thousands of millions of years after the origin of life, and its causes are not fully known yet. On the other hand, the jump to multicellularity took place several times, which suggests that it could be a case of convergent evolution, and so likely to take place on other planets as well. Palaeontologist Simon Conway Morris considers that convergent evolution would lead to kingdoms similar to our plants and animals, and that many features are likely to develop in alien animals as well, such as bilateral symmetry, limbs, digestive systems and heads with sensory organs. Scientists from the University of Oxford analysed it from the perspective of evolutionary theory and wrote in a study in the International Journal of Astrobiology that aliens may be similar to humans. The planetary context would also have an influence: a planet with higher gravity would have smaller animals, and other types of stars can lead to non-green photosynthesizers. The amount of energy available would also affect biodiversity, as an ecosystem sustained by black smokers or hydrothermal vents would have less energy available than those sustained by a star's light and heat, and so its lifeforms would not grow beyond a certain complexity. There is also research in assessing the capacity of life for developing intelligence. It has been suggested that this capacity arises with the number of potential niches a planet contains, and that the complexity of life itself is reflected in the information density of planetary environments, which in turn can be computed from its niches. It is common knowledge that the conditions on other planets in the solar system, in addition to the many galaxies outside of the Milky Way galaxy, are very harsh and seem to be too extreme to harbor any life. The environmental conditions on these planets can have intense UV radiation paired with extreme temperatures, lack of water, and much more that can lead to conditions that don't seem to favor the creation or maintenance of extraterrestrial life. However, there has been much historical evidence that some of the earliest and most basic forms of life on Earth originated in some extreme environments that seem unlikely to have harbored life at least at one point in Earth's history. Fossil evidence as well as many historical theories backed up by years of research and studies have marked environments like hydrothermal vents or acidic hot springs as some of the first places that life could have originated on Earth. These environments can be considered extreme when compared to the typical ecosystems that the majority of life on Earth now inhabit, as hydrothermal vents are scorching hot due to the magma escaping from the Earth's mantle and meeting the much colder oceanic water. Even in today's world, there can be a diverse population of bacteria found inhabiting the area surrounding these hydrothermal vents which can suggest that some form of life can be supported even in the harshest of environments like the other planets in the solar system. The aspects of these harsh environments that make them ideal for the origin of life on Earth, as well as the possibility of creation of life on other planets, is the chemical reactions forming spontaneously. For example, the hydrothermal vents found on the ocean floor are known to support many chemosynthetic processes which allow organisms to utilize energy through reduced chemical compounds that fix carbon. In return, these reactions will allow for organisms to live in relatively low oxygenated environments while maintaining enough energy to support themselves. The early Earth environment was reducing and therefore, these carbon fixing compounds were necessary for the survival and possible origin of life on Earth. With the little amount of information that scientists have found regarding the atmosphere on other planets in the Milky Way galaxy and beyond, the atmospheres are most likely reducing or with very low oxygen levels, especially when compared with Earth's atmosphere. If there were the necessary elements and ions on these planets, the same carbon fixing, reduced chemical compounds occurring around hydrothermal vents could also occur on these planets' surfaces and possibly result in the origin of extraterrestrial life. Planetary habitability in the Solar System The Solar System has a wide variety of planets, dwarf planets, and moons, and each one is studied for its potential to host life. Each one has its own specific conditions that may benefit or harm life. So far, the only lifeforms found are those from Earth. No extraterrestrial intelligence other than humans exists or has ever existed within the Solar System. Astrobiologist Mary Voytek points out that it would be unlikely to find large ecosystems, as they would have already been detected by now. The inner Solar System is likely devoid of life. However, Venus is still of interest to astrobiologists, as it is a terrestrial planet that was likely similar to Earth in its early stages and developed in a different way. There is a greenhouse effect, the surface is the hottest in the Solar System, sulfuric acid clouds, all surface liquid water is lost, and it has a thick carbon-dioxide atmosphere with huge pressure. Comparing both helps to understand the precise differences that lead to beneficial or harmful conditions for life. And despite the conditions against life on Venus, there are suspicions that microbial life-forms may still survive in high-altitude clouds. Mars is a cold and almost airless desert, inhospitable to life. However, recent studies revealed that water on Mars used to be quite abundant, forming rivers, lakes, and perhaps even oceans. Mars may have been habitable back then, and life on Mars may have been possible. But when the planetary core ceased to generate a magnetic field, solar winds removed the atmosphere and the planet became vulnerable to solar radiation. Ancient life-forms may still have left fossilised remains, and microbes may still survive deep underground. As mentioned, the gas giants and ice giants are unlikely to contain life. The most distant solar system bodies, found in the Kuiper Belt and outwards, are locked in permanent deep-freeze, but cannot be ruled out completely. Although the giant planets themselves are highly unlikely to have life, there is much hope to find it on moons orbiting these planets. Europa, from the Jovian system, has a subsurface ocean below a thick layer of ice. Ganymede and Callisto also have subsurface oceans, but life is less likely in them because water is sandwiched between layers of solid ice. Europa would have contact between the ocean and the rocky surface, which helps the chemical reactions. It may be difficult to dig so deep in order to study those oceans, though. Enceladus, a tiny moon of Saturn with another subsurface ocean, may not need to be dug, as it releases water to space in eruption columns. The space probe Cassini flew inside one of these, but could not make a full study because NASA did not expect this phenomenon and did not equip the probe to study ocean water. Still, Cassini detected complex organic molecules, salts, evidence of hydrothermal activity, hydrogen, and methane. Titan is the only celestial body in the Solar System besides Earth that has liquid bodies on the surface. It has rivers, lakes, and rain of hydrocarbons, methane, and ethane, and even a cycle similar to Earth's water cycle. This special context encourages speculations about lifeforms with different biochemistry, but the cold temperatures would make such chemistry take place at a very slow pace. Water is rock-solid on the surface, but Titan does have a subsurface water ocean like several other moons. However, it is of such a great depth that it would be very difficult to access it for study. Scientific search The science that searches and studies life in the universe, both on Earth and elsewhere, is called astrobiology. With the study of Earth's life, the only known form of life, astrobiology seeks to study how life starts and evolves and the requirements for its continuous existence. This helps to determine what to look for when searching for life in other celestial bodies. This is a complex area of study, and uses the combined perspectives of several scientific disciplines, such as astronomy, biology, chemistry, geology, oceanography, and atmospheric sciences. The scientific search for extraterrestrial life is being carried out both directly and indirectly. As of September 2017[update], 3,667 exoplanets in 2,747 systems have been identified, and other planets and moons in the Solar System hold the potential for hosting primitive life such as microorganisms. As of 8 February 2021, an updated status of studies considering the possible detection of lifeforms on Venus (via phosphine) and Mars (via methane) was reported. Scientists search for biosignatures within the Solar System by studying planetary surfaces and examining meteorites. Some claim to have identified evidence that microbial life has existed on Mars. In 1996, a controversial report stated that structures resembling nanobacteria were discovered in a meteorite, ALH84001, formed of rock ejected from Mars. Although all the unusual properties of the meteorite were eventually explained as the result of inorganic processes, the controversy over its discovery laid the groundwork for the development of astrobiology. An experiment on the two Viking Mars landers reported gas emissions from heated Martian soil samples that some scientists argue are consistent with the presence of living microorganisms. Lack of corroborating evidence from other experiments on the same samples suggests that a non-biological reaction is a more likely hypothesis. In February 2005 NASA scientists reported they may have found some evidence of extraterrestrial life on Mars. The two scientists, Carol Stoker and Larry Lemke of NASA's Ames Research Center, based their claim on methane signatures found in Mars's atmosphere resembling the methane production of some forms of primitive life on Earth, as well as on their own study of primitive life near the Rio Tinto river in Spain. NASA officials soon distanced NASA from the scientists' claims, and Stoker herself backed off from her initial assertions. In November 2011, NASA launched the Mars Science Laboratory that landed the Curiosity rover on Mars. It is designed to assess the past and present habitability on Mars using a variety of scientific instruments. The rover landed on Mars at Gale Crater in August 2012. A group of scientists at Cornell University started a catalog of microorganisms, with the way each one reacts to sunlight. The goal is to help with the search for similar organisms in exoplanets, as the starlight reflected by planets rich in such organisms would have a specific spectrum, unlike that of starlight reflected from lifeless planets. If Earth was studied from afar with this system, it would reveal a shade of green, as a result of the abundance of plants with photosynthesis. In August 2011, NASA studied meteorites found on Antarctica, finding adenine, guanine, hypoxanthine, and xanthine. Adenine and guanine are components of DNA, and the others are used in other biological processes. The studies ruled out pollution of the meteorites on Earth, as those components would not be freely available the way they were found in the samples. This discovery suggests that several organic molecules that serve as building blocks of life may be generated within asteroids and comets. In October 2011, scientists reported that cosmic dust contains complex organic compounds ("amorphous organic solids with a mixed aromatic-aliphatic structure") that could be created naturally, and rapidly, by stars. It is still unclear if those compounds played a role in the creation of life on Earth, but Sun Kwok, of the University of Hong Kong, thinks so. "If this is the case, life on Earth may have had an easier time getting started as these organics can serve as basic ingredients for life." In August 2012, and in a world first, astronomers at Copenhagen University reported the detection of a specific sugar molecule, glycolaldehyde, in a distant star system. The molecule was found around the protostellar binary IRAS 16293-2422, which is located 400 light years from Earth. Glycolaldehyde is needed to form ribonucleic acid, or RNA, which is similar in function to DNA. This finding suggests that complex organic molecules may form in stellar systems prior to the formation of planets, eventually arriving on young planets early in their formation. In December 2023, astronomers reported the first time discovery, in the plumes of Enceladus, moon of the planet Saturn, of hydrogen cyanide, a possible chemical essential for life as we know it, as well as other organic molecules, some of which are yet to be better identified and understood. According to the researchers, "these [newly discovered] compounds could potentially support extant microbial communities or drive complex organic synthesis leading to the origin of life." Although most searches are focused on the biology of extraterrestrial life, an extraterrestrial intelligence capable enough to develop a civilization may be detectable by other means as well. Technology may generate technosignatures, effects on the native planet that may not be caused by natural causes. There are three main types of techno-signatures considered: interstellar communications, effects on the atmosphere, and planetary-sized structures such as Dyson spheres. Organizations such as the SETI Institute search the cosmos for potential forms of communication. They started with radio waves, and now search for laser pulses as well. The challenge for this search is that there are natural sources of such signals as well, such as gamma-ray bursts and supernovae, and the difference between a natural signal and an artificial one would be in its specific patterns. Astronomers intend to use artificial intelligence for this, as it can manage large amounts of data and is devoid of biases and preconceptions. Besides, even if there is an advanced extraterrestrial civilization, there is no guarantee that it is transmitting radio communications in the direction of Earth. The length of time required for a signal to travel across space means that a potential answer may arrive decades or centuries after the initial message. The atmosphere of Earth is rich in nitrogen dioxide as a result of air pollution, which can be detectable. The natural abundance of carbon, which is also relatively reactive, makes it likely to be a basic component of the development of a potential extraterrestrial technological civilization, as it is on Earth. Fossil fuels may likely be generated and used on such worlds as well. The abundance of chlorofluorocarbons in the atmosphere can also be a clear technosignature, considering their role in ozone depletion. Light pollution may be another technosignature, as multiple lights on the night side of a rocky planet can be a sign of advanced technological development. However, modern telescopes are not strong enough to study exoplanets with the required level of detail to perceive it. The Kardashev scale proposes that a civilization may eventually start consuming energy directly from its local star. This would require giant structures built next to it, called Dyson spheres. Those speculative structures would cause an excess infrared radiation, that telescopes may notice. The infrared radiation is typical of young stars, surrounded by dusty protoplanetary disks that will eventually form planets. An older star such as the Sun would have no natural reason to have excess infrared radiation. The presence of heavy elements in a star's light-spectrum is another potential biosignature; such elements would (in theory) be found if the star were being used as an incinerator/repository for nuclear waste products. Some astronomers search for extrasolar planets that may be conducive to life, narrowing the search to terrestrial planets within the habitable zones of their stars. Since 1992, over four thousand exoplanets have been discovered (6,128 planets in 4,584 planetary systems including 1,017 multiple planetary systems as of 30 October 2025). The extrasolar planets so far discovered range in size from that of terrestrial planets similar to Earth's size to that of gas giants larger than Jupiter. The number of observed exoplanets is expected to increase greatly in the coming years.[better source needed] The Kepler space telescope has also detected a few thousand candidate planets, of which about 11% may be false positives. There is at least one planet on average per star. About 1 in 5 Sun-like stars[a] have an "Earth-sized"[b] planet in the habitable zone,[c] with the nearest expected to be within 12 light-years distance from Earth. Assuming 200 billion stars in the Milky Way,[d] that would be 11 billion potentially habitable Earth-sized planets in the Milky Way, rising to 40 billion if red dwarfs are included. The rogue planets in the Milky Way possibly number in the trillions. The nearest known exoplanet is Proxima Centauri b, located 4.2 light-years (1.3 pc) from Earth in the southern constellation of Centaurus. As of March 2014[update], the least massive exoplanet known is PSR B1257+12 A, which is about twice the mass of the Moon. The most massive planet listed on the NASA Exoplanet Archive is DENIS-P J082303.1−491201 b, about 29 times the mass of Jupiter, although according to most definitions of a planet, it is too massive to be a planet and may be a brown dwarf instead. Almost all of the planets detected so far are within the Milky Way, but there have also been a few possible detections of extragalactic planets. The study of planetary habitability also considers a wide range of other factors in determining the suitability of a planet for hosting life. One sign that a planet probably already contains life is the presence of an atmosphere with significant amounts of oxygen, since that gas is highly reactive and generally would not last long without constant replenishment. This replenishment occurs on Earth through photosynthetic organisms. One way to analyse the atmosphere of an exoplanet is through spectrography when it transits its star, though this might only be feasible with dim stars like white dwarfs. History and cultural impact The modern concept of extraterrestrial life is based on assumptions that were not commonplace during the early days of astronomy. The first explanations for the celestial objects seen in the night sky were based on mythology. Scholars from Ancient Greece were the first to consider that the universe is inherently understandable and rejected explanations based on supernatural incomprehensible forces, such as the myth of the Sun being pulled across the sky in the chariot of Apollo. They had not developed the scientific method yet and based their ideas on pure thought and speculation, but they developed precursor ideas to it, such as that explanations had to be discarded if they contradict observable facts. The discussions of those Greek scholars established many of the pillars that would eventually lead to the idea of extraterrestrial life, such as Earth being round and not flat. The cosmos was first structured in a geocentric model that considered that the sun and all other celestial bodies revolve around Earth. However, they did not consider them as worlds. In Greek understanding, the world was composed by both Earth and the celestial objects with noticeable movements. Anaximander thought that the cosmos was made from apeiron, a substance that created the world, and that the world would eventually return to the cosmos. Eventually two groups emerged, the atomists that thought that matter at both Earth and the cosmos was equally made of small atoms of the classical elements (earth, water, fire and air), and the Aristotelians who thought that those elements were exclusive of Earth and that the cosmos was made of a fifth one, the aether. Atomist Epicurus thought that the processes that created the world, its animals and plants should have created other worlds elsewhere, along with their own animals and plants. Aristotle thought instead that all the earth element naturally fell towards the center of the universe, and that would make it impossible for other planets to exist elsewhere. Under that reasoning, Earth was not only in the center, it was also the only planet in the universe. Cosmic pluralism, the plurality of worlds, or simply pluralism, describes the philosophical belief in numerous "worlds" in addition to Earth, which might harbor extraterrestrial life. The earliest recorded assertion of extraterrestrial human life is found in ancient scriptures of Jainism. There are multiple "worlds" mentioned in Jain scriptures that support human life. These include, among others, Bharat Kshetra, Mahavideh Kshetra, Airavat Kshetra, and Hari kshetra. Medieval Muslim writers like Fakhr al-Din al-Razi and Muhammad al-Baqir supported cosmic pluralism on the basis of the Qur'an. Chaucer's poem The House of Fame engaged in medieval thought experiments that postulated the plurality of worlds. However, those ideas about other worlds were different from the current knowledge about the structure of the universe, and did not postulate the existence of planetary systems other than the Solar System. When those authors talk about other worlds, they talk about places located at the center of their own systems, and with their own stellar vaults and cosmos surrounding them. The Greek ideas and the disputes between atomists and Aristotelians outlived the fall of the Greek empire. The Great Library of Alexandria compiled information about it, part of which was translated by Islamic scholars and thus survived the end of the Library. Baghdad combined the knowledge of the Greeks, the Indians, the Chinese and its own scholars, and the knowledge expanded through the Byzantine Empire. From there it eventually returned to Europe by the time of the Middle Ages. However, as the Greek atomist doctrine held that the world was created by random movements of atoms, with no need for a creator deity, it became associated with atheism, and the dispute intertwined with religious ones. Still, the Church did not react to those topics in a homogeneous way, and there were stricter and more permissive views within the church itself. The first known mention of the term 'panspermia' was in the writings of the 5th-century BC Greek philosopher Anaxagoras. He proposed the idea that life exists everywhere. By the time of the late Middle Ages there were many known inaccuracies in the geocentric model, but it was kept in use because naked eye observations provided limited data. Nicolaus Copernicus started the Copernican Revolution by proposing that the planets revolve around the sun rather than Earth. His proposal had little acceptance at first because, as he kept the assumption that orbits were perfect circles, his model led to as many inaccuracies as the geocentric one. Tycho Brahe improved the available data with naked-eye observatories, which worked with highly complex sextants and quadrants. Tycho could not make sense of his observations, but Johannes Kepler did: orbits were not perfect circles, but ellipses. This knowledge benefited the Copernican model, which worked now almost perfectly. The invention of the telescope a short time later, perfected by Galileo Galilei, clarified the final doubts, and the paradigm shift was completed. Under this new understanding, the notion of extraterrestrial life became feasible: if Earth is but just a planet orbiting around a star, there may be planets similar to Earth elsewhere. The astronomical study of distant bodies also proved that physical laws are the same elsewhere in the universe as on Earth, with nothing making the planet truly special. The new ideas were met with resistance from the Catholic church. Galileo was tried for the heliocentric model, which was considered heretical, and forced to recant it. The best-known early-modern proponent of ideas of extraterrestrial life was the Italian philosopher Giordano Bruno, who argued in the 16th century for an infinite universe in which every star is surrounded by its own planetary system. Bruno wrote that other worlds "have no less virtue nor a nature different to that of our earth" and, like Earth, "contain animals and inhabitants". Bruno's belief in the plurality of worlds was one of the charges leveled against him by the Venetian Holy Inquisition, which tried and executed him. The heliocentric model was further strengthened by the postulation of the theory of gravity by Sir Isaac Newton. This theory provided the mathematics that explains the motions of all things in the universe, including planetary orbits. By this point, the geocentric model was definitely discarded. By this time, the use of the scientific method had become a standard, and new discoveries were expected to provide evidence and rigorous mathematical explanations. Science also took a deeper interest in the mechanics of natural phenomena, trying to explain not just the way nature works but also the reasons for working that way. There was very little actual discussion about extraterrestrial life before this point, as the Aristotelian ideas remained influential while geocentrism was still accepted. When it was finally proved wrong, it not only meant that Earth was not the center of the universe, but also that the lights seen in the sky were not just lights, but physical objects. The notion that life may exist in them as well soon became an ongoing topic of discussion, although one with no practical ways to investigate. The possibility of extraterrestrials remained a widespread speculation as scientific discovery accelerated. William Herschel, the discoverer of Uranus, was one of many 18th–19th-century astronomers who believed that the Solar System is populated by alien life. Other scholars of the period who championed "cosmic pluralism" included Immanuel Kant and Benjamin Franklin. At the height of the Enlightenment, even the Sun and Moon were considered candidates for extraterrestrial inhabitants. Speculation about life on Mars increased in the late 19th century, following telescopic observation of apparent Martian canals – which soon, however, turned out to be optical illusions. Despite this, in 1895, American astronomer Percival Lowell published his book Mars, followed by Mars and its Canals in 1906, proposing that the canals were the work of a long-gone civilisation. Spectroscopic analysis of Mars's atmosphere began in earnest in 1894, when U.S. astronomer William Wallace Campbell showed that neither water nor oxygen was present in the Martian atmosphere. By 1909 better telescopes and the best perihelic opposition of Mars since 1877 conclusively put an end to the canal hypothesis. As a consequence of the belief in the spontaneous generation there was little thought about the conditions of each celestial body: it was simply assumed that life would thrive anywhere. This theory was disproved by Louis Pasteur in the 19th century. Popular belief in thriving alien civilisations elsewhere in the solar system still remained strong until Mariner 4 and Mariner 9 provided close images of Mars, which debunked forever the idea of the existence of Martians and decreased the previous expectations of finding alien life in general. The end of the spontaneous generation belief forced investigation into the origin of life. Although abiogenesis is the more accepted theory, a number of authors reclaimed the term "panspermia" and proposed that life was brought to Earth from elsewhere. Some of those authors are Jöns Jacob Berzelius (1834), Kelvin (1871), Hermann von Helmholtz (1879) and, somewhat later, by Svante Arrhenius (1903). The science fiction genre, although not so named during the time, developed during the late 19th century. The expansion of the genre of extraterrestrials in fiction influenced the popular perception over the real-life topic, making people eager to jump to conclusions about the discovery of aliens. Science marched at a slower pace, some discoveries fueled expectations and others dashed excessive hopes. For example, with the advent of telescopes, most structures seen on the Moon or Mars were immediately attributed to Selenites or Martians, and later ones (such as more powerful telescopes) revealed that all such discoveries were natural features. A famous case is the Cydonia region of Mars, first imaged by the Viking 1 orbiter. The low-resolution photos showed a rock formation that resembled a human face, but later spacecraft took photos in higher detail that showed that there was nothing special about the site. The search and study of extraterrestrial life became a science of its own, astrobiology. Also known as exobiology, this discipline is studied by the NASA, the ESA, the INAF, and others. Astrobiology studies life from Earth as well, but with a cosmic perspective. For example, abiogenesis is of interest to astrobiology, not because of the origin of life on Earth, but for the chances of a similar process taking place in other celestial bodies. Many aspects of life, from its definition to its chemistry, are analyzed as either likely to be similar in all forms of life across the cosmos or only native to Earth. Astrobiology, however, remains constrained by the current lack of extraterrestrial life-forms to study, as all life on Earth comes from the same ancestor, and it is hard to infer general characteristics from a group with a single example to analyse. The 20th century came with great technological advances, speculations about future hypothetical technologies, and an increased basic knowledge of science by the general population thanks to science divulgation through the mass media. The public interest in extraterrestrial life and the lack of discoveries by mainstream science led to the emergence of pseudosciences that provided affirmative, if questionable, answers to the existence of aliens. Ufology claims that many unidentified flying objects (UFOs) would be spaceships from alien species, and ancient astronauts hypothesis claim that aliens would have visited Earth in antiquity and prehistoric times but people would have failed to understand it by then. Most UFOs or UFO sightings can be readily explained as sightings of Earth-based aircraft (including top-secret aircraft), known astronomical objects or weather phenomenons, or as hoaxes. Looking beyond the pseudosciences, Lewis White Beck strove to elevate the level of public discourse on the topic of extraterrestrial life by tracing the evolution of philosophical thought over the centuries from ancient times into the modern era. His review of the contributions made by Lucretius, Plutarch, Aristotle, Copernicus, Immanuel Kant, John Wilkins, Charles Darwin and Karl Marx demonstrated that even in modern times, humanity could be profoundly influenced in its search for extraterrestrial life by subtle and comforting archetypal ideas which are largely derived from firmly held religious, philosophical and existential belief systems. On a positive note, however, Beck further argued that even if the search for extraterrestrial life proves to be unsuccessful, the endeavor itself could have beneficial consequences by assisting humanity in its attempt to actualize superior ways of living here on Earth. By the 21st century, it was accepted that multicellular life in the Solar System can only exist on Earth, but the interest in extraterrestrial life increased regardless. This is a result of the advances in several sciences. The knowledge of planetary habitability allows to consider on scientific terms the likelihood of finding life at each specific celestial body, as it is known which features are beneficial and harmful for life. Astronomy and telescopes also improved to the point exoplanets can be confirmed and even studied, increasing the number of search places. Life may still exist elsewhere in the Solar System in unicellular form, but the advances in spacecraft allow to send robots to study samples in situ, with tools of growing complexity and reliability. Although no extraterrestrial life has been found and life may still be just a rarity from Earth, there are scientific reasons to suspect that it can exist elsewhere, and technological advances that may detect it if it does. Many scientists are optimistic about the chances of finding alien life. In the words of SETI's Frank Drake, "All we know for sure is that the sky is not littered with powerful microwave transmitters". Drake noted that it is entirely possible that advanced technology results in communication being carried out in some way other than conventional radio transmission. At the same time, the data returned by space probes, and giant strides in detection methods, have allowed science to begin delineating habitability criteria on other worlds, and to confirm that at least other planets are plentiful, though aliens remain a question mark. The Wow! signal, detected in 1977 by a SETI project, remains a subject of speculative debate. On the other hand, other scientists are pessimistic. Jacques Monod wrote that "Man knows at last that he is alone in the indifferent immensity of the universe, whence which he has emerged by chance". In 2000, geologist and paleontologist Peter Ward and astrobiologist Donald Brownlee published a book entitled Rare Earth: Why Complex Life is Uncommon in the Universe.[better source needed] In it, they discussed the Rare Earth hypothesis, in which they claim that Earth-like life is rare in the universe, whereas microbial life is common. Ward and Brownlee are open to the idea of evolution on other planets that is not based on essential Earth-like characteristics such as DNA and carbon. As for the possible risks, theoretical physicist Stephen Hawking warned in 2010 that humans should not try to contact alien life forms. He warned that aliens might pillage Earth for resources. "If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans", he said. Jared Diamond had earlier expressed similar concerns. On 20 July 2015, Hawking and Russian billionaire Yuri Milner, along with the SETI Institute, announced a well-funded effort, called the Breakthrough Initiatives, to expand efforts to search for extraterrestrial life. The group contracted the services of the 100-meter Robert C. Byrd Green Bank Telescope in West Virginia in the United States and the 64-meter Parkes Telescope in New South Wales, Australia. On 13 February 2015, scientists (including Geoffrey Marcy, Seth Shostak, Frank Drake and David Brin) at a convention of the American Association for the Advancement of Science, discussed Active SETI and whether transmitting a message to possible intelligent extraterrestrials in the Cosmos was a good idea; one result was a statement, signed by many, that a "worldwide scientific, political and humanitarian discussion must occur before any message is sent". Government responses The 1967 Outer Space Treaty and the 1979 Moon Agreement define rules of planetary protection against potentially hazardous extraterrestrial life. COSPAR also provides guidelines for planetary protection. A committee of the United Nations Office for Outer Space Affairs had in 1977 discussed for a year strategies for interacting with extraterrestrial life or intelligence. The discussion ended without any conclusions. As of 2010, the UN lacks response mechanisms for the case of an extraterrestrial contact. One of the NASA divisions is the Office of Safety and Mission Assurance (OSMA), also known as the Planetary Protection Office. A part of its mission is to "rigorously preclude backward contamination of Earth by extraterrestrial life." In 2016, the Chinese Government released a white paper detailing its space program. According to the document, one of the research objectives of the program is the search for extraterrestrial life. It is also one of the objectives of the Chinese Five-hundred-meter Aperture Spherical Telescope (FAST) program. In 2020, Dmitry Rogozin, the head of the Russian space agency, said the search for extraterrestrial life is one of the main goals of deep space research. He also acknowledged the possibility of existence of primitive life on other planets of the Solar System. The French space agency has an office for the study of "non-identified aero spatial phenomena". The agency is maintaining a publicly accessible database of such phenomena, with over 1600 detailed entries. According to the head of the office, the vast majority of entries have a mundane explanation; but for 25% of entries, their extraterrestrial origin can neither be confirmed nor denied. In 2020, chairman of the Israel Space Agency Isaac Ben-Israel stated that the probability of detecting life in outer space is "quite large". But he disagrees with his former colleague Haim Eshed who stated that there are contacts between an advanced alien civilisation and some of Earth's governments. In fiction Although the idea of extraterrestrial peoples became feasible once astronomy developed enough to understand the nature of planets, they were not thought of as being any different from humans. Having no scientific explanation for the origin of mankind and its relation to other species, there was no reason to expect them to be any other way. This was changed by the 1859 book On the Origin of Species by Charles Darwin, which proposed the theory of evolution. Now with the notion that evolution on other planets may take other directions, science fiction authors created bizarre aliens, clearly distinct from humans. A usual way to do that was to add body features from other animals, such as insects or octopuses. Costuming and special effects feasibility alongside budget considerations forced films and TV series to tone down the fantasy, but these limitations lessened since the 1990s with the advent of computer-generated imagery (CGI), and later on as CGI became more effective and less expensive. Real-life events sometimes captivate people's imagination and this influences the works of fiction. For example, during the Barney and Betty Hill incident, the first recorded claim of an alien abduction, the couple reported that they were abducted and experimented on by aliens with oversized heads, big eyes, pale grey skin, and small noses, a description that eventually became the grey alien archetype once used in works of fiction.

Lily Hay NewmanSecurityFeb 16, 2026 6:30 AMThe El Paso No-Fly Debacle Is Just the Beginning of a Drone Defense MessFears over a drug cartel drone over Texas sparked a recent airspace shutdown in El Paso and New Mexico, highlighting just how tricky it can be to deploy anti-drone weapons near cities.Photograph: Getty ImagesSave StorySave this storySave StorySave this storyA shocking but ultimately brief airspace closure over El Paso, Texas, and parts of New Mexico last week is stoking unease among pilots and the broader public about the status of United States anti-drone defenses.As low-cost UAV equipment proliferates around the world, analysts have repeatedly warned that destructive attacks perpetrated using drones are inevitable. It is challenging to develop nimble and safe countermeasures, though, given that things like jamming or attempting to shoot down a drone are difficult—or even impossible—to carry out safely in populated areas, much less densely populated cities.In the case of the El Paso incident, the Federal Aviation Administration originally set the airspace closure to last 10 days, but ultimately lifted it after eight hours. The Trump administration initially said the move was related to possible incursion of Mexican drug cartel drones, but the New York Times and others reported that it came from FAA concerns that Customs and Border Protection officials were using a Pentagon-provided anti-drone laser weapon in the area despite questions about potential dangers to civilian aircraft.CBP reportedly used the laser defense tool to shoot down what turned out to be a party balloon.“The FAA likely did a very intelligent thing by issuing the Temporary Flight Restriction,” says Tarah Wheeler, chief security officer of the cybersecurity consultancy TPO Group. “The initial 10-day length of the TFR makes it seem like the FAA wasn’t provided with information on how long the laser would be in use. The FAA doesn’t want to close down airspace longer than they have to.”The FAA, Department of Defense, and Department of Homeland Security did not respond to WIRED's requests for comment.A White House official told The Hill on Thursday that an FAA administrator made the decision to close the airspace without notifying the White House, the Pentagon, or DHS.“The Department of War and the Department of Transportation having been working together for months regarding drone incursion operations. Last night’s action to disable the cartel drones was not a spontaneous action,” the official told The Hill in a statement. “At no point in the process of disabling these cartel drones were civilian aircraft in danger as a result of the methods used by DOW to disable the drones.”Also on Thursday, US representatives Veronica Escobar of Texas and Gabe Vasquez of New Mexico, along with New Mexico senators Martin Heinrich and Ben Ray Luján, wrote to DHS secretary Kristi Noem, defense secretary Pete Hegseth, and transportation secretary Sean Duffy to request a classified briefing on the incident.The lawmakers wrote that they want representatives from each agency “to speak to the roles they played, acknowledge where the failed communication occurred, and share the steps you are taking to ensure a future crisis of this nature will not reoccur.”The laser tool used in the situation was a “LOCUST” anti-drone weapon system made by the defense company AeroVironment (AV), according to a Reuters report. The LOCUST system is a 20-kilowatt laser directed energy weapon, a relatively low-power tool made to be used to take out small drones. (AV acquired LOCUST creator BlueHalo in November 2024.)“The recent proliferation of inexpensive and readily available drones has shifted the focus to short-range air defense, where lasers and high-powered microwaves offer a potentially game-changing advantage,” an Army report on a laser weapons test said in June.AV delivered two sets of LOCUST units to the US Army in September and December as part of the Army Multi-Purpose High Energy Laser (AMP-HEL) prototyping project—one of a few “Directed Energy Efforts” that the Army's Directed Energy Prototyping Office undertook in 2025.Deployment of anti-drone defense measures is becoming a bigger priority in the US and around the world, but integrating them safely is challenging and experts say there need to be new protocols and communication mechanisms in place to protect both civilian and military aviation. Even the most seemingly innocuous laser pointers or other laser-equipped tools, for example, can pose risks to pilots and aviation. Sources told the Associated Press that before last week's incident, a meeting had already been scheduled between the FAA and the Pentagon for later this month to discuss use of the technology.Multiple private and commercial pilots, who requested anonymity because they are not authorized to speak to the press, told WIRED that they found the series of events to be extremely troubling.As one put it, “I do not want to be stuck anywhere for 10 days or get hit by a laser. There is currently no procedure for that.” The El Paso No-Fly Debacle Is Just the Beginning of a Drone Defense Mess A shocking but ultimately brief airspace closure over El Paso, Texas, and parts of New Mexico last week is stoking unease among pilots and the broader public about the status of United States anti-drone defenses. As low-cost UAV equipment proliferates around the world, analysts have repeatedly warned that destructive attacks perpetrated using drones are inevitable.

In the case of the El Paso incident, the Federal Aviation Administration originally set the airspace closure to last 10 days, but ultimately lifted it after eight hours. The Trump administration initially said the move was related to possible incursion of Mexican drug cartel drones, but the New York Times and others reported that it came from FAA concerns that Customs and Border Protection officials were using a Pentagon-provided anti-drone laser weapon in the area despite questions about potential dangers to civilian aircraft. CBP reportedly used the laser defense tool to shoot down what turned out to be a party balloon. “The FAA likely did a very intelligent thing by issuing the Temporary Flight Restriction,” says Tarah Wheeler, chief security officer of the cybersecurity consultancy TPO Group. “The initial 10-day length of the TFR makes it seem like the FAA wasn’t provided with information on how long the laser would be in use. The FAA doesn’t want to close down airspace longer than they have to.” The FAA, Department of Defense, and Department of Homeland Security did not respond to WIRED's requests for comment. A White House official told The Hill on Thursday that an FAA administrator made the decision to close the airspace without notifying the White House, the Pentagon, or DHS. “The Department of War and the Department of Transportation having been working together for months regarding drone incursion operations. Last night’s action to disable the cartel drones was not a spontaneous action,” the official told The Hill in a statement. “At no point in the process of disabling these cartel drones were civilian aircraft in danger as a result of the methods used by DOW to disable the drones.” Also on Thursday, US representatives Veronica Escobar of Texas and Gabe Vasquez of New Mexico, along with New Mexico senators Martin Heinrich and Ben Ray Luján, wrote to DHS secretary Kristi Noem, defense secretary Pete Hegseth, and transportation secretary Sean Duffy to request a classified briefing on the incident. The lawmakers wrote that they want representatives from each agency “to speak to the roles they played, acknowledge where the failed communication occurred, and share the steps you are taking to ensure a future crisis of this nature will not reoccur.” The laser tool used in the situation was a “LOCUST” anti-drone weapon system made by the defense company AeroVironment (AV), according to a Reuters report. The LOCUST system is a 20-kilowatt laser directed energy weapon, a relatively low-power tool made to be used to take out small drones. (AV acquired LOCUST creator BlueHalo in November 2024.) “The recent proliferation of inexpensive and readily available drones has shifted the focus to short-range air defense, where lasers and high-powered microwaves offer a potentially game-changing advantage,” an Army report on a laser weapons test said in June. AV delivered two sets of LOCUST units to the US Army in September and December as part of the Army Multi-Purpose High Energy Laser (AMP-HEL) prototyping project—one of a few “Directed Energy Efforts” that the Army's Directed Energy Prototyping Office undertook in 2025. Deployment of anti-drone defense measures is becoming a bigger priority in the US and around the world, but integrating them safely is challenging and experts say there need to be new protocols and communication mechanisms in place to protect both civilian and military aviation. Even the most seemingly innocuous laser pointers or other laser-equipped tools, for example, can pose risks to pilots and aviation. Sources told the Associated Press that before last week's incident, a meeting had already been scheduled between the FAA and the Pentagon for later this month to discuss use of the technology. Multiple private and commercial pilots, who requested anonymity because they are not authorized to speak to the press, told WIRED that they found the series of events to be extremely troubling. As one put it, “I do not want to be stuck anywhere for 10 days or get hit by a laser. There is currently no procedure for that.” You Might Also Like In your inbox: Upgrade your life with WIRED-tested gear A wave of unexplained bot traffic is sweeping the web Big Story: The women training for pregnancy like it’s a marathon Iran’s digital surveillance machine is almost complete Listen: Silicon Valley tech workers are trying to stop ICE © 2026 Condé Nast.

Contents BBC News BBC News is an operational business division of the British Broadcasting Corporation (BBC) responsible for the gathering and broadcasting of news and current affairs in the UK and around the world. The department is the world's largest broadcast news organisation and generates about 120 hours of radio and television output each day, as well as online news coverage. The service has over 5,500 journalists working across its output including in 50 foreign news bureaus where more than 250 foreign correspondents are stationed. Deborah Turness has been the CEO of news and current affairs since September 2022. In 2019, it was reported in an Ofcom report that the BBC spent £136m on news during the period April 2018 to March 2019. BBC News' domestic, global and online news divisions are housed within the largest live newsroom in Europe, in Broadcasting House in central London. Parliamentary coverage is produced and broadcast from studios in London. Through BBC English Regions, the BBC also has regional centres across England and national news centres in Northern Ireland, Scotland and Wales. All nations and English regions produce their own local news programmes and other current affairs and sport programmes. The BBC is a quasi-autonomous corporation authorised by royal charter, making it operationally independent of the government. As of 2024, the BBC reaches an average of 450 million people per week, with the BBC World Service accounting for 320 million people. History This is London calling – 2LO calling. Here is the first general news bulletin, copyright by Reuters, Press Association, Exchange Telegraph and Central News. — BBC news programme opening during the 1920s The British Broadcasting Company broadcast its first radio bulletin from radio station 2LO on 14 November 1922. Wishing to avoid competition, newspaper publishers persuaded the government to ban the BBC from broadcasting news before 7 pm, and to force it to use wire service copy instead of reporting on its own. The BBC gradually gained the right to edit the copy and, in 1934, created its own news operation. However, it could not broadcast news before 6 p.m. until World War II. In addition to news, Gaumont British and Movietone cinema newsreels had been broadcast on the TV service since 1936, with the BBC producing its own equivalent Television Newsreel programme from January 1948. A weekly Children's Newsreel was inaugurated on 23 April 1950, to around 350,000 receivers. The network began simulcasting its radio news on television in 1946, with a still picture of Big Ben. Televised bulletins began on 5 July 1954, broadcast from leased studios within Alexandra Palace in London. The public's interest in television and live events was stimulated by Elizabeth II's coronation in 1953. It is estimated that up to 27 million people viewed the programme in the UK, overtaking radio's audience of 12 million for the first time. Those live pictures were fed from 21 cameras in central London to Alexandra Palace for transmission, and then on to other UK transmitters opened in time for the event. That year, there were around two million TV Licences held in the UK, rising to over three million the following year, and four and a half million by 1955. Television news, although physically separate from its radio counterpart, was still firmly under radio news' control in the 1950s. Correspondents provided reports for both outlets, and the first televised bulletin, shown on 5 July 1954 on the then BBC television service and presented by Richard Baker, involved his providing narration off-screen while stills were shown. This was then followed by the customary Television Newsreel with a recorded commentary by John Snagge (and on other occasions by Andrew Timothy). On-screen newsreaders were introduced a year later in 1955 – Kenneth Kendall (the first to appear in vision), Robert Dougall, and Richard Baker—three weeks before ITN's launch on 21 September 1955. Mainstream television production had started to move out of Alexandra Palace in 1950 to larger premises – mainly at Lime Grove Studios in Shepherd's Bush, west London – taking Current Affairs (then known as Talks Department) with it. It was from here that the first Panorama, a new documentary programme, was transmitted on 11 November 1953, with Richard Dimbleby becoming anchor in 1955. In 1958, Hugh Carleton Greene became head of News and Current Affairs. On 1 January 1960, Greene became Director-General. Greene made changes that were aimed at making BBC reporting more similar to its competitor ITN, which had been highly rated by study groups held by Greene. A newsroom was created at Alexandra Palace, television reporters were recruited and given the opportunity to write and voice their own scripts, without having to cover stories for radio too. On 20 June 1960, Nan Winton, the first female BBC network newsreader, appeared in vision. 19 September 1960 saw the start of the radio news and current affairs programme The Ten O'clock News. BBC2 started transmission on 20 April 1964 and began broadcasting a new show, Newsroom. The World at One, a lunchtime news programme, began on 4 October 1965 on the then Home Service, and the year before News Review had started on television. News Review was a summary of the week's news, first broadcast on Sunday, 26 April 1964 on BBC 2 and harking back to the weekly Newsreel Review of the Week, produced from 1951, to open programming on Sunday evenings–the difference being that this incarnation had subtitles for the deaf and hard-of-hearing. As this was the decade before electronic caption generation, each superimposition ("super") had to be produced on paper or card, synchronised manually to studio and news footage, committed to tape during the afternoon, and broadcast early evening. Thus Sundays were no longer a quiet day for news at Alexandra Palace. The programme ran until the 1980s – by then using electronic captions, known as Anchor – to be superseded by Ceefax subtitling (a similar Teletext format), and the signing of such programmes as See Hear (from 1981). On Sunday 17 September 1967, The World This Weekend, a weekly news and current affairs programme, launched on what was then Home Service, but soon-to-be Radio 4. Preparations for colour began in the autumn of 1967 and on Thursday 7 March 1968 Newsroom on BBC2 moved to an early evening slot, becoming the first UK news programme to be transmitted in colour – from Studio A at Alexandra Palace. News Review and Westminster (the latter a weekly review of Parliamentary happenings) were "colourised" shortly after. However, much of the insert material was still in black and white, as initially only a part of the film coverage shot in and around London was on colour reversal film stock, and all regional and many international contributions were still in black and white. Colour facilities at Alexandra Palace were technically very limited for the next eighteen months, as it had only one RCA colour Quadruplex videotape machine and, eventually two Pye plumbicon colour telecines–although the news colour service started with just one. Black and white national bulletins on BBC 1 continued to originate from Studio B on weekdays, along with Town and Around, the London regional "opt out" programme broadcast throughout the 1960s (and the BBC's first regional news programme for the South East), until it started to be replaced by Nationwide on Tuesday to Thursday from Lime Grove Studios early in September 1969. Town and Around was never to make the move to Television Centre – instead it became London This Week which aired on Mondays and Fridays only, from the new TVC studios. The BBC moved production out of Alexandra Palace in 1969. BBC Television News resumed operations the next day with a lunchtime bulletin on BBC1 – in black and white – from Television Centre, where it remained until March 2013. This move to a smaller studio with better technical facilities allowed Newsroom and News Review to replace back projection with colour-separation overlay. During the 1960s, satellite communication had become possible; however, it was some years before digital line-store conversion was able to undertake the process seamlessly. On 14 September 1970, the first Nine O'Clock News was broadcast on television. Robert Dougall presented the first week from studio N1 – described by The Guardian as "a sort of polystyrene padded cell"—the bulletin having been moved from the earlier time of 20.50 as a response to the ratings achieved by ITN's News at Ten, introduced three years earlier on the rival ITV. Richard Baker and Kenneth Kendall presented subsequent weeks, thus echoing those first television bulletins of the mid-1950s. Angela Rippon became the first female news presenter of the Nine O'Clock News in 1975. Her work outside the news was controversial at the time, appearing on The Morecambe and Wise Christmas Show in 1976 singing and dancing. The first edition of John Craven's Newsround, initially intended only as a short series and later renamed just Newsround, came from studio N3 on 4 April 1972. Afternoon television news bulletins during the mid to late 1970s were broadcast from the BBC newsroom itself, rather than one of the three news studios. The newsreader would present to camera while sitting on the edge of a desk; behind him staff would be seen working busily at their desks. This period corresponded with when the Nine O'Clock News got its next makeover, and would use a CSO background of the newsroom from that very same camera each weekday evening. Also in the mid-1970s, the late night news on BBC2 was briefly renamed Newsnight, but this was not to last, or be the same programme as we know today – that would be launched in 1980 – and it soon reverted to being just a news summary with the early evening BBC2 news expanded to become Newsday. News on radio was to change in the 1970s, and on Radio 4 in particular, brought about by the arrival of new editor Peter Woon from television news and the implementation of the Broadcasting in the Seventies report. These included the introduction of correspondents into news bulletins where previously only a newsreader would present, as well as the inclusion of content gathered in the preparation process. New programmes were also added to the daily schedule, PM and The World Tonight as part of the plan for the station to become a "wholly speech network". Newsbeat launched as the news service on Radio 1 on 10 September 1973. On 23 September 1974, a teletext system which was launched to bring news content on television screens using text only was launched. Engineers originally began developing such a system to bring news to deaf viewers, but the system was expanded. The Ceefax service became much more diverse before it ceased on 23 October 2012: it not only had subtitling for all channels, it also gave information such as weather, flight times and film reviews. By the end of the decade, the practice of shooting on film for inserts in news broadcasts was declining, with the introduction of ENG technology into the UK. The equipment would gradually become less cumbersome – the BBC's first attempts had been using a Philips colour camera with backpack base station and separate portable Sony U-matic recorder in the latter half of the decade. In 1980, the Iranian Embassy Siege had been shot electronically by the BBC Television News Outside broadcasting team, and the work of reporter Kate Adie, broadcasting live from Prince's Gate, was nominated for BAFTA actuality coverage, but this time beaten by ITN for the 1980 award. Newsnight, the news and current affairs programme, was due to go on air on 23 January 1980, although trade union disagreements meant that its launch from Lime Grove was postponed by a week. On 27 August 1981 Moira Stuart became the first African Caribbean female newsreader to appear on British television. By 1982, ENG technology had become sufficiently reliable for Bernard Hesketh to use an Ikegami camera to cover the Falklands War, coverage for which he won the "Royal Television Society Cameraman of the Year" award and a BAFTA nomination – the first time that BBC News had relied upon an electronic camera, rather than film, in a conflict zone. BBC News won the BAFTA for its actuality coverage, however the event has become remembered in television terms for Brian Hanrahan's reporting where he coined the phrase "I'm not allowed to say how many planes joined the raid, but I counted them all out and I counted them all back" to circumvent restrictions, and which has become cited as an example of good reporting under pressure. The first BBC breakfast television programme, Breakfast Time also launched during the 1980s, on 17 January 1983 from Lime Grove Studio E and two weeks before its ITV rival TV-am. Frank Bough, Selina Scott, and Nick Ross helped to wake viewers with a relaxed style of presenting. The Six O'Clock News first aired on 3 September 1984, eventually becoming the most watched news programme in the UK (however, since 2006 it has been overtaken by the BBC News at Ten). In October 1984, images of millions of people starving to death in the Ethiopian famine were shown in Michael Buerk's Six O'Clock News reports. The BBC News crew were the first to document the famine, with Buerk's report on 23 October describing it as "a biblical famine in the 20th century" and "the closest thing to hell on Earth". The BBC News report shocked Britain, motivating its citizens to inundate relief agencies, such as Save the Children, with donations, and to bring global attention to the crisis in Ethiopia. The news report was also watched by Bob Geldof, who would organise the charity single "Do They Know It's Christmas?" to raise money for famine relief followed by the Live Aid concert in July 1985. Starting in 1981, the BBC gave a common theme to its main news bulletins with new electronic titles–a set of computer-animated "stripes" forming a circle on a red background with a "BBC News" typescript appearing below the circle graphics, and a theme tune consisting of brass and keyboards. The Nine used a similar (striped) number 9. The red background was replaced by a blue from 1985 until 1987. By 1987, the BBC had decided to re-brand its bulletins and established individual styles again for each one with differing titles and music, the weekend and holiday bulletins branded in a similar style to the Nine, although the "stripes" introduction continued to be used until 1989 on occasions where a news bulletin was screened out of the running order of the schedule. In 1987, John Birt resurrected the practice of correspondents working for both TV and radio with the introduction of bi-media journalism. During the 1990s, a wider range of services began to be offered by BBC News, with the split of BBC World Service Television to become BBC World (news and current affairs), and BBC Prime (light entertainment). Content for a 24-hour news channel was thus required, followed in 1997 with the launch of domestic equivalent BBC News 24. Rather than set bulletins, ongoing reports and coverage was needed to keep both channels functioning and meant a greater emphasis in budgeting for both was necessary. In 1998, after 66 years at Broadcasting House, the BBC Radio News operation moved to BBC Television Centre. New technology, provided by Silicon Graphics, came into use in 1993 for a re-launch of the main BBC 1 bulletins, creating a virtual set which appeared to be much larger than it was physically. The relaunch also brought all bulletins into the same style of set with only small changes in colouring, titles, and music to differentiate each. A computer generated cut-glass sculpture of the BBC coat of arms was the centrepiece of the programme titles until the large scale corporate rebranding of news services in 1999. In November 1997, BBC News Online was launched, following individual webpages for major news events such as the 1996 Olympic Games, 1997 general election, and the death of Princess Diana. In 1999, the biggest relaunch occurred, with BBC One bulletins, BBC World, BBC News 24, and BBC News Online all adopting a common style. One of the most significant changes was the gradual adoption of the corporate image by the BBC regional news programmes, giving a common style across local, national and international BBC television news. This also included Newyddion, the main news programme of Welsh language channel S4C, produced by BBC News Wales. Following the relaunch of BBC News in 1999, regional headlines were included at the start of the BBC One news bulletins in 2000. The English regions did however lose five minutes at the end of their bulletins, due to a new headline round-up at 18:55. 2000 also saw the Nine O'Clock News moved to the later time of 22:00. This was in response to ITN who had just moved their popular News at Ten programme to 23:00. ITN briefly returned News at Ten but following poor ratings when head-to-head against the BBC's Ten O'Clock News, the ITN bulletin was moved to 22.30, where it remained until 14 January 2008. The retirement in 2009 of Peter Sissons and departure of Michael Buerk from the Ten O'Clock News led to changes in the BBC One bulletin presenting team on 20 January 2003. The Six O'Clock News became double headed with George Alagiah and Sophie Raworth after Huw Edwards and Fiona Bruce moved to present the Ten. A new set design featuring a projected fictional newsroom backdrop was introduced, followed on 16 February 2004 by new programme titles to match those of BBC News 24. BBC News 24 and BBC World introduced a new style of presentation in December 2003, that was slightly altered on 5 July 2004 to mark 50 years of BBC Television News. On 7 March 2005 director general Mark Thompson launched the "Creative Futures" project to restructure the organisation. The individual positions of editor of the One and Six O'Clock News were replaced by a new daytime position in November 2005. Kevin Bakhurst became the first Controller of BBC News 24, replacing the position of editor. Amanda Farnsworth became daytime editor while Craig Oliver was later named editor of the Ten O'Clock News. Bulletins received new titles and a new set design in May 2006, to allow for Breakfast to move into the main studio for the first time since 1997. The new set featured Barco videowall screens with a background of the London skyline used for main bulletins and originally an image of cirrus clouds against a blue sky for Breakfast. This was later replaced following viewer criticism. The studio bore similarities with the ITN-produced ITV News in 2004, though ITN uses a CSO Virtual studio rather than the actual screens at BBC News. BBC News became part of a new BBC Journalism group in November 2006 as part of a restructuring of the BBC. The then-Director of BBC News, Helen Boaden reported to the then-Deputy Director-General and head of the journalism group, Mark Byford until he was made redundant in 2010. On 18 October 2007, ED Mark Thompson announced a six-year plan, "Delivering Creative Futures" (based on his project begun in March 2005), merging the television current affairs department into a new "News Programmes" division. Thompson's announcement, in response to a £2 billion shortfall in funding, would, he said, deliver "a smaller but fitter BBC" in the digital age, by cutting its payroll and, in 2013, selling Television Centre. The various separate newsrooms for television, radio and online operations were merged into a single multimedia newsroom. Programme making within the newsrooms was brought together to form a multimedia programme making department. BBC World Service director Peter Horrocks said that the changes would achieve efficiency at a time of cost-cutting at the BBC. In his blog, he wrote that by using the same resources across the various broadcast media meant fewer stories could be covered, or by following more stories, there would be fewer ways to broadcast them. A new graphics and video playout system was introduced for production of television bulletins in January 2007. This coincided with a new structure to BBC World News bulletins, editors favouring a section devoted to analysing the news stories reported on. The first new BBC News bulletin since the Six O'Clock News was announced in July 2007 following a successful trial in the Midlands. The summary, lasting 90 seconds, has been broadcast at 20:00 on weekdays since December 2007 and bears similarities with 60 Seconds on BBC Three, but also includes headlines from the various BBC regions and a weather summary. As part of a long-term cost cutting programme, bulletins were renamed the BBC News at One, Six and Ten respectively in April 2008 while BBC News 24 was renamed BBC News and moved into the same studio as the bulletins at BBC Television Centre. BBC World was renamed BBC World News and regional news programmes were also updated with the new presentation style, designed by Lambie-Nairn. 2008 also saw tri-media introduced across TV, radio, and online. The studio moves also meant that Studio N9, previously used for BBC World, was closed, and operations moved to the previous studio of BBC News 24. Studio N9 was later refitted to match the new branding, and was used for the BBC's UK local elections and European elections coverage in early June 2009. A strategy review of the BBC in March 2010, confirmed that having "the best journalism in the world" would form one of five key editorial policies, as part of changes subject to public consultation and BBC Trust approval. After a period of suspension in late 2012, Helen Boaden ceased to be the Director of BBC News. On 16 April 2013, incoming BBC Director-General Tony Hall named James Harding, a former editor of The Times of London newspaper as Director of News and Current Affairs. From August 2012 to March 2013, all news operations moved from Television Centre to new facilities in the refurbished and extended Broadcasting House, in Portland Place. The move began in October 2012, and also included the BBC World Service, which moved from Bush House following the expiry of the BBC's lease. This new extension to the north and east, referred to as "New Broadcasting House", includes several new state-of-the-art radio and television studios centred around an 11-storey atrium. The move began with the domestic programme The Andrew Marr Show on 2 September 2012, and concluded with the move of the BBC News channel and domestic news bulletins on 18 March 2013. The newsroom houses all domestic bulletins and programmes on both television and radio, as well as the BBC World Service international radio networks and the BBC World News international television channel. BBC News and CBS News established an editorial and newsgathering partnership in 2017, replacing an earlier long-standing partnership between BBC News and ABC News. In an October 2018 Simmons Research survey of 38 news organisations, BBC News was ranked the fourth most trusted news organisation by Americans, behind CBS News, ABC News and The Wall Street Journal. In January 2020 the BBC announced a BBC News savings target of £80 million per year by 2022, involving about 450 staff reductions from the current 6,000. BBC director of news and current affairs Fran Unsworth said there would be further moves toward digital broadcasting, in part to attract back a youth audience, and more pooling of reporters to stop separate teams covering the same news. A further 70 staff reductions were announced in July 2020. BBC Three began airing the news programme The Catch Up in February 2022. It is presented by Levi Jouavel, Kirsty Grant, and Callum Tulley and aims to get the channel's target audience (16 to 34-year olds) to make sense of the world around them while also highlighting optimistic stories. Compared to its predecessor 60 Seconds, The Catch Up is three times longer, running for about three minutes and not airing during weekends. According to its annual report as of December 2021[update], India has the largest number of people using BBC services in the world. In May 2025, following the earthquake that hit Myanmar and Thailand, a television news bulletin (BBC News Myanmar) from the Burmese service using a vacated Voice of America satellite frequency began its broadcasts. Programming and reporting In November 2023, BBC News joined with the International Consortium of Investigative Journalists, Paper Trail Media [de] and 69 media partners including Distributed Denial of Secrets and the Organised Crime and Corruption Reporting Project (OCCRP) and more than 270 journalists in 55 countries and territories to produce the 'Cyprus Confidential' report on the financial network which supports the regime of Vladimir Putin, mostly with connections to Cyprus, and showed Cyprus to have strong links with high-up figures in the Kremlin, some of whom have been sanctioned. Government officials including Cyprus president Nikos Christodoulides and European lawmakers began responding to the investigation's findings in less than 24 hours, calling for reforms and launching probes. BBC News is responsible for the news programmes and documentary content on the BBC's general television channels, as well as the news coverage on the BBC News Channel in the UK, and 22 hours of programming for the corporation's international BBC World News channel. Coverage for BBC Parliament is carried out on behalf of the BBC at Millbank Studios, though BBC News provides editorial and journalistic content. BBC News content is also output onto the BBC's digital interactive television services under the BBC Red Button brand, and until 2012, on the Ceefax teletext system. The music on all BBC television news programmes was introduced in 1999 and composed by David Lowe. It was part of the re-branding which commenced in 1999 and features 'BBC Pips'. The general theme was used on bulletins on BBC One, News 24, BBC World and local news programmes in the BBC's Nations and Regions. Lowe was also responsible for the music on Radio One's Newsbeat. The theme has had several changes since 1999, the latest in March 2013. The BBC Arabic Television news channel launched on 11 March 2008, a Persian-language channel followed on 14 January 2009, broadcasting from the Peel wing of Broadcasting House; both include news, analysis, interviews, sports and highly cultural programmes and are run by the BBC World Service and funded from a grant-in-aid from the British Foreign Office (and not the television licence). The BBC Verify service was launched in 2023 to fact-check news stories, followed by BBC Verify Live in 2025. BBC Radio News produces bulletins for the BBC's national radio stations and provides content for local BBC radio stations via the General News Service (GNS), a BBC-internal news distribution service. BBC News does not produce the BBC's regional news bulletins, which are produced individually by the BBC nations and regions themselves. The BBC World Service broadcasts to some 150 million people in English as well as 27 languages across the globe. BBC Radio News is a patron of the Radio Academy. BBC News Online is the BBC's news website. Launched in November 1997, it is one of the most popular news websites, with 1.2 billion website visits in April 2021, as well as being used by 60% of the UK's internet users for news. The website contains international news coverage as well as entertainment, sport, science, and political news. Mobile apps for Android, iOS and Windows Phone systems have been provided since 2010. Many television and radio programmes are also available to view on the BBC iPlayer and BBC Sounds services. The BBC News channel is also available to view 24 hours a day, while video and radio clips are also available within online news articles. In October 2019, BBC News Online launched a mirror on the dark web anonymity network Tor in an effort to circumvent censorship. Criticism The BBC is required by its charter to be free from both political and commercial influence and answers only to its viewers and listeners. This political objectivity is sometimes questioned. For instance, The Daily Telegraph (3 August 2005) carried a letter from the KGB defector Oleg Gordievsky, referring to it as "The Red Service". Books have been written on the subject, including anti-BBC works like Truth Betrayed by W J West and The Truth Twisters by Richard Deacon. The BBC has been accused of bias by Conservative MPs. The BBC's Editorial Guidelines on Politics and Public Policy state that while "the voices and opinions of opposition parties must be routinely aired and challenged", "the government of the day will often be the primary source of news". The BBC is regularly accused by the government of the day of bias in favour of the opposition and, by the opposition, of bias in favour of the government. Similarly, during times of war, the BBC is often accused by the UK government, or by strong supporters of British military campaigns, of being overly sympathetic to the view of the enemy. An edition of Newsnight at the start of the Falklands War in 1982 was described as "almost treasonable" by John Page, MP, who objected to Peter Snow saying "if we believe the British". During the first Gulf War, critics of the BBC took to using the satirical name "Baghdad Broadcasting Corporation". During the Kosovo War, the BBC were labelled the "Belgrade Broadcasting Corporation" (suggesting favouritism towards the FR Yugoslavia government over ethnic Albanian rebels) by British ministers, although Slobodan Milosević (then FRY president) claimed that the BBC's coverage had been biased against his nation. Conversely, some of those who style themselves anti-establishment in the United Kingdom or who oppose foreign wars have accused the BBC of pro-establishment bias or of refusing to give an outlet to "anti-war" voices. Following the 2003 invasion of Iraq, a study by the Cardiff University School of Journalism of the reporting of the war found that nine out of 10 references to weapons of mass destruction during the war assumed that Iraq possessed them, and only one in 10 questioned this assumption. It also found that, out of the main British broadcasters covering the war, the BBC was the most likely to use the British government and military as its source. It was also the least likely to use independent sources, like the Red Cross, who were more critical of the war. When it came to reporting Iraqi casualties, the study found fewer reports on the BBC than on the other three main channels. The report's author, Justin Lewis, wrote "Far from revealing an anti-war BBC, our findings tend to give credence to those who criticised the BBC for being too sympathetic to the government in its war coverage. Either way, it is clear that the accusation of BBC anti-war bias fails to stand up to any serious or sustained analysis." Prominent BBC appointments are constantly assessed by the British media and political establishment for signs of political bias. The appointment of Greg Dyke as Director-General was highlighted by press sources because Dyke was a Labour Party member and former activist, as well as a friend of Tony Blair. The BBC's former Political Editor, Nick Robinson, was some years ago a chairman of the Young Conservatives and did, as a result, attract informal criticism from the former Labour government, but his predecessor Andrew Marr faced similar claims from the right because he was editor of The Independent, a liberal-leaning newspaper, before his appointment in 2000. Mark Thompson, former Director-General of the BBC, admitted the organisation has been biased "towards the left" in the past. He said, "In the BBC I joined 30 years ago, there was, in much of current affairs, in terms of people's personal politics, which were quite vocal, a massive bias to the left". He then added, "The organization did struggle then with impartiality. Now it is a completely different generation. There is much less overt tribalism among the young journalists who work for the BBC." Following the EU referendum in 2016, some critics suggested that the BBC was biased in favour of leaving the EU. For instance, in 2018, the BBC received complaints from people who took issue that the BBC was not sufficiently covering anti-Brexit marches while giving smaller-scale events hosted by former UKIP leader Nigel Farage more airtime. On the other hand, a poll released by YouGov showed that 45% of people who voted to leave the EU thought that the BBC was 'actively anti-Brexit' compared to 13% of the same kinds of voters who think the BBC is pro-Brexit. In 2008, the BBC Hindi was criticised by some Indian outlets for referring to the terrorists who carried out the 2008 Mumbai attacks as "gunmen". The response to this added to prior criticism from some Indian commentators suggesting that the BBC may have an Indophobic bias. In March 2015, the BBC was criticised for a BBC Storyville documentary interviewing one of the rapists in India. In spite of a ban ordered by the Indian High court, the BBC still aired the documentary "India's Daughter" outside India. BBC News was at the centre of a political controversy following the 2003 invasion of Iraq. Three BBC News reports (Andrew Gilligan's on Today, Gavin Hewitt's on The Ten O'Clock News and another on Newsnight) quoted an anonymous source that stated the British government (particularly the Prime Minister's office) had embellished the September Dossier with misleading exaggerations of Iraq's weapons of mass destruction capabilities. The government denounced the reports and accused the corporation of poor journalism. In subsequent weeks the corporation stood by the report, saying that it had a reliable source. Following intense media speculation, David Kelly was named in the press as the source for Gilligan's story on 9 July 2003. Kelly was found dead, by suicide, in a field close to his home early on 18 July. An inquiry led by Lord Hutton was announced by the British government the following day to investigate the circumstances leading to Kelly's death, concluding that "Dr. Kelly took his own life." In his report on 28 January 2004, Lord Hutton concluded that Gilligan's original accusation was "unfounded" and the BBC's editorial and management processes were "defective". In particular, it specifically criticised the chain of management that caused the BBC to defend its story. The BBC Director of News, Richard Sambrook, the report said, had accepted Gilligan's word that his story was accurate in spite of his notes being incomplete. Davies had then told the BBC Board of Governors that he was happy with the story and told the Prime Minister that a satisfactory internal inquiry had taken place. The Board of Governors, under the chairman's, Gavyn Davies, guidance, accepted that further investigation of the Government's complaints were unnecessary. Because of the criticism in the Hutton report, Davies resigned on the day of publication. BBC News faced an important test, reporting on itself with the publication of the report, but by common consent (of the Board of Governors) managed this "independently, impartially and honestly". Davies' resignation was followed by the resignation of Director General, Greg Dyke, the following day, and the resignation of Gilligan on 30 January. While undoubtedly a traumatic experience for the corporation, an ICM poll in April 2003 indicated that it had sustained its position as the best and most trusted provider of news. The BBC has faced accusations of holding both anti-Israel and anti-Palestine bias. Douglas Davis, the London correspondent of The Jerusalem Post, has described the BBC's coverage of the Arab–Israeli conflict as "a relentless, one-dimensional portrayal of Israel as a demonic, criminal state and Israelis as brutal oppressors [which] bears all the hallmarks of a concerted campaign of vilification that, wittingly or not, has the effect of delegitimising the Jewish state and pumping oxygen into a dark old European hatred that dared not speak its name for the past half-century.". However two large independent studies, one conducted by Loughborough University and the other by Glasgow University's Media Group concluded that Israeli perspectives are given greater coverage. Critics of the BBC argue that the Balen Report proves systematic bias against Israel in headline news programming. The Daily Mail and The Daily Telegraph criticised the BBC for spending hundreds of thousands of British tax payers' pounds from preventing the report being released to the public. Jeremy Bowen, the Middle East Editor for BBC world news, was singled out specifically for bias by the BBC Trust which concluded that he violated "BBC guidelines on accuracy and impartiality." An independent panel appointed by the BBC Trust was set up in 2006 to review the impartiality of the BBC's coverage of the Israeli–Palestinian conflict. The panel's assessment was that "apart from individual lapses, there was little to suggest deliberate or systematic bias." While noting a "commitment to be fair accurate and impartial" and praising much of the BBC's coverage the independent panel concluded "that BBC output does not consistently give a full and fair account of the conflict. In some ways the picture is incomplete and, in that sense, misleading." It notes that, "the failure to convey adequately the disparity in the Israeli and Palestinian experience, [reflects] the fact that one side is in control and the other lives under occupation". Writing in the Financial Times, Philip Stephens, one of the panellists, later accused the BBC's director-general, Mark Thompson, of misrepresenting the panel's conclusions. He further opined "My sense is that BBC news reporting has also lost a once iron-clad commitment to objectivity and a necessary respect for the democratic process. If I am right, the BBC, too, is lost". Mark Thompson published a rebuttal in the FT the next day. The description by one BBC correspondent reporting on the funeral of Yassir Arafat that she had been left with tears in her eyes led to other questions of impartiality, particularly from Martin Walker in a guest opinion piece in The Times, who picked out the apparent case of Fayad Abu Shamala, the BBC Arabic Service correspondent, who told a Hamas rally on 6 May 2001, that journalists in Gaza were "waging the campaign shoulder to shoulder together with the Palestinian people". Walker argues that the independent inquiry was flawed for two reasons. Firstly, because the time period over which it was conducted (August 2005 to January 2006) surrounded the Israeli withdrawal from Gaza and Ariel Sharon's stroke, which produced more positive coverage than usual. Furthermore, he wrote, the inquiry only looked at the BBC's domestic coverage, and excluded output on the BBC World Service and BBC World. Tom Gross accused the BBC of glorifying Hamas suicide bombers, and condemned its policy of inviting guests such as Jenny Tonge and Tom Paulin who have compared Israeli soldiers to Nazis. Writing for the BBC, Paulin said Israeli soldiers should be "shot dead" like Hitler's S.S, and said he could "understand how suicide bombers feel". The BBC also faced criticism for not airing a Disasters Emergency Committee aid appeal for Palestinians who suffered in Gaza during 22-day war there between late 2008 and early 2009. Most other major UK broadcasters did air this appeal, but rival Sky News did not. British journalist Julie Burchill has accused BBC of creating a "climate of fear" for British Jews over its "excessive coverage" of Israel compared to other nations. In light of the Gaza war, the BBC suspended seven Arab journalists over allegations of expressing support for Hamas via social media. BBC and ABC share video segments and reporters as needed in producing their newscasts. with the BBC showing ABC World News Tonight with David Muir in the UK. However, in July 2017, the BBC announced a new partnership with CBS News allows both organisations to share video, editorial content, and additional newsgathering resources in New York, London, Washington and around the world. BBC News subscribes to wire services from leading international agencies including PA Media (formerly Press Association), Reuters, and Agence France-Presse. In April 2017, the BBC dropped Associated Press in favour of an enhanced service from AFP. BBC News reporters and broadcasts are now and have in the past been banned in several countries primarily for reporting which has been unfavourable to the ruling government. For example, correspondents were banned by the former apartheid regime of South Africa. The BBC was banned in Zimbabwe under Mugabe for eight years as a terrorist organisation until being allowed to operate again over a year after the 2008 elections. The BBC was banned in Burma (officially Myanmar) after their coverage and commentary on anti-government protests there in September 2007. The ban was lifted four years later in September 2011. Other cases have included Uzbekistan, China, and Pakistan. BBC Persian, the BBC's Persian language news site, was blocked from the Iranian internet in 2006. The BBC News website was made available in China again in March 2008, but as of October 2014[update], was blocked again. In June 2015, the Rwandan government placed an indefinite ban on BBC broadcasts following the airing of a controversial documentary regarding the 1994 Rwandan genocide, Rwanda's Untold Story, broadcast on BBC2 on 1 October 2014. The UK's Foreign Office recognised "the hurt caused in Rwanda by some parts of the documentary". In February 2017, reporters from the BBC (as well as the Daily Mail, The New York Times, Politico, CNN, and others) were denied access to a United States White House briefing. In 2017, BBC India was banned for a period of five years from covering all national parks and sanctuaries in India. Following the withdrawal of CGTN's UK broadcaster licence on 4 February 2021 by Ofcom, China banned BBC News from airing in China. See also References External links |below = Category }} |

She has more than 13 years of experience reporting on wearables, health tech, and more. Before coming to The Verge, she worked for Gizmodo and PC Magazine.This is Optimizer, a weekly newsletter sent every Friday from Verge senior reviewer Victoria Song that dissects and discusses the latest gizmos and potions that swear they’re going to change your life. Opt in for Optimizer here.While scrolling through my TikTok feed, I often find myself thinking of Elizabeth Báthory. Legend has it that Báthory, a powerful 16th-century Hungarian countess, would kill virgins and bathe in their blood to retain her youth. Historians have debated whether Báthory really was a serial killer, though most agree she probably didn’t actually bathe in blood. Still, she’s what I think of anytime I see how far vanity will take us: vampire facials, snail mucin, bird poop treatments, and now Rejuran — a Korean skincare serum with the hottest new ingredient, PDRN. In case you were unaware, PDRN comes from salmon sperm.Usually, these ads show skinfluencers with bouncy, hydrated skin extracting a clear liquid from a silver bottle. This serum, they say, is a game changer. Rubbing it into your face will promote skin rejuvenation, elasticity, and collagen production. The result is enhanced healing, improved skin texture, and reduced wrinkles, and it’s all thanks to patented science. Rejuran’s PDRN molecule is 670 times smaller than your pores, meaning enhanced absorption.You can be the most skeptical person on the planet, but it’s hard to argue with the human desire to be young and beautiful.“PDRN stands for polydeoxyribonucleotide, which essentially is just a DNA fragment,” says Victoria Fu, a cosmetic chemist and one of the founders behind the Chemist Confessions skincare brand. “Super old-school PDRN treatments actually come from human placenta, but now salmon sperm PDRN has become the industry standard.”According to Fu, beauty trends like injectables often stem from the medical field. Before it became a hot skincare ingredient, PDRN was studied as an injected therapeutic treatment for conditions like diabetic foot ulcers, and there are some promising studies for injectable PDRN that suggest it could be helpful for wound healing — though PDRN injectables haven’t been FDA-approved in the US. Generally speaking, injectables are considered more effective for rapid, dramatic, and structural changes, as they’re able to deliver ingredients deeper into the skin. Injectable hyaluronic acid, for instance, is more effective at restoring volume than topical hyaluronic acid.Online, PDRN started gaining notoriety a few years ago as skinfluencers shuttled themselves to South Korea for salmon DNA facials. In the typical video, these beauty influencers would giggle. Come with me to get a salmon sperm facial! Usually, a doctor is shown injecting PDRN into the skin every few millimeters until the influencer’s face is riddled with tiny, swollen mounds. It hurts so much! Recovery takes so long! But just LOOK at this glow!!! The painful treatment blew up once celebrities like Kim Kardashian and Jennifer Aniston admitted to incorporating salmon sperm facials into their routines. And then, about a year ago, Rejuran — the company behind the injections — announced a topical version. No scary needles, no need to fly to Korea, and a bottle costs about $52, whereas the facial could run anywhere from $500 to $700. Now, you can find PDRN in all kinds of skincare products ranging from eye creams to sunscreen.Despite authoring this newsletter, I’m not immune to wellness fads. I covet glass skin like any other vain 30-something afraid of the harsh ravages of time. I’ve bought the stupid TikTok skincare wand that influencers said was “clinically proven” and that Hailey Bieber uses. I reviewed its clinical studies on electroporation — microcurrents that supposedly tear tiny holes in your skin to help products absorb better — and knew it was dubious (if relatively harmless).Which is to say, I knew it was a red flag when I heard an influencer in a Rejuran ad say the product was “clinically proven,” but I bought a bottle anyway. I’ve used two bottles of Rejuran’s topical ampoule and other skincare products marketing hot new ingredients like volufiline, because that’s the power of science-adjacent wellness marketing. (Volufiline is a new plant-based compound that’s marketed as “topical filler” because it stimulates fat cell production.)Still, if you truly could replicate injectable results in an easily accessible serum — that’s a compelling claim. So I asked Fu if any of the claims about topical PDRN being as effective as injected skincare treatments held water.“There’s some early research supporting PDRN in medical and aesthetic procedures, but evidence for topical PDRN is still very limited,” says Fu. “A serum cannot be a non-invasive substitute for an injectable procedure.”The reason is straightforward. Even if there’s evidence that PDRN itself could be an effective ingredient, the mode of delivery matters.“Injectable treatments deliver material directly into skin tissue at concentrations and depths topical products simply won’t be able to achieve,” says Fu.But silly things like facts aren’t enough to stop skincare brands from jumping on experimental fads so long as they’re not technically harmful.Just the other day, I was served a video from megaviral beauty influencer Mikayla Nogueira announcing to her 17 million followers that she’s launching a salmon-derived PDRN face ampoule and eye serum for her own cosmetics line.“A science-backed duo powered by PDRN that is going to lift, firm, plump your skin plus so much more. Not to mention these products are made in Korea, dermatologist tested, clinically tested, and proven to do exactly what they say they’re going to do,” Nogueira says in the ad. She goes on to say that she worked with Korean cosmetics chemists, and uses phrases like “low molecular weight” and “efficacious” levels.I have no doubt Nogueira believes in PDRN products. But as I wrote in a recent Optimizer, “clinically tested” and “science-backed” are marketing phrases that don’t always mean what you think.Meanwhile, other brands are advertising less icky versions of PDRN derived from plants. There are ginseng-derived PDRN products on the market, like the VT Cosmetics PDRN Essence 100, and the Medicube PDRN Pink Peptide Serum derived from roses. Supposedly, these brands would have you believe plant-based PDRN is just as effective and a vegan alternative.So what is the truth?“PDRN source, purity, molecular size, and stabilization all matter,” says Fu. “‘Plant-based PDRN’ is a bit of a marketing gray area. It may be DNA fragments, but it’s not automatically equivalent to the clinical material studied in medical literature. Two products can list PDRN and behave very differently. The good news is we are seeing more studies come out on these plant PDRNs, so hopefully we can better gauge these different sources soon.”Fu says all things considered, PDRN is a “relatively vanilla” skincare active that’s unlikely to irritate your skin and is fine for curious skincare hobbyists to experiment with. But that also means it’s not a foundational part of any skincare routine. Things like sunscreen, moisturizers, and well-studied actives like retinoids are more likely to do the heavy lifting in any regimen. Like most things in the wellness space, the main harm that PDRN poses is to your wallet. Fu says that consistency and patience are the key to getting real, long-term results. (Unfortunately, these are also the two things most consumers would like to bypass.)“Social media has made it possible for consumers to hear from industry insiders like ourselves,” Fu says, referring to herself and her partner, Gloria Lu. In addition to running their own cosmetics brand, the two chemists also write a skincare science education blog and host a podcast. “But the flip side is that consumers will also hear a LOT of noise and contradicting information from all sorts of directions.”Fu says the smart thing to do is look at any testing a brand is willing to share and look for quantifiable grading metrics over consumer perception. As in, “34 percent improvement in elasticity” is a more meaningful claim than “90 percent of users agree they saw an improvement in skin hydration in two weeks.” Before and after pictures, she says, can also be misleading due to inconsistent lighting or face angles. If a claim sounds too good to be true, it likely is.“We try to remind everyone to refrain from a ‘knee-jerk’ reaction and not to let the trends distract you from sticking to the fundamentals of your routine,” says Fu.Having spent the past three months slathering a salmon sperm serum on my face, I honestly couldn’t tell you if it’s improved my skin. Maybe it’s a smidge glowier. I think it helped with one stubborn acne scar. I knew that I wouldn’t see dramatic results going in, just as I knew that the trendy volufiline serums that skinfluencers claim are “filler in a bottle” wouldn’t fix my undereyes. Is it egregious that I know better and still partook? Maybe. But to Fu’s point, I’m religious about the fundamentals — sunscreen, moisturizer, and as of recently, tretinoin, which I incorporated after consulting my dermatologist. The point is that I’ve done my homework and made an informed choice.It just so happened that this time, I thought experimenting with salmon jizz serums was harmless fun.Follow topics and authors from this story to see more like this in your personalized homepage feed and to receive email updates.Victoria SongCloseVictoria SongSenior Reviewer, Wearable TechPosts from this author will be added to your daily email digest and your homepage feed.FollowFollowSee All by Victoria SongColumnCloseColumnPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All ColumnHealthCloseHealthPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All HealthOptimizerCloseOptimizerPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All OptimizerScienceCloseSciencePosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All ScienceMost PopularMost PopularXbox chief Phil Spencer is leaving MicrosoftThe RAM shortage is coming for everything you care aboutRead Microsoft gaming CEO Asha Sharma’s first memo on the future of XboxAmazon blames human employees for an AI coding agent’s mistakeWill Stancil, man of the people or just an annoying guy?The Verge DailyA free daily digest of the news that matters most.Email (required)Sign UpBy submitting your email, you agree to our Terms and Privacy Notice.

Research indicates that some users, particularly young women, are more likely to use Mixi to connect in more private ways with close friends, particularly in contrast to perceptions of Facebook as a more public social network. The corporate headquarters are on the seventh floor of the Shibuya Scramble Square (渋谷スクランブルスクエア, JA) in Shibuya, Tokyo. History Mixi has enjoyed a steady growth in its user base. In 2005, the website had more than one million users, and less than a year later, it had more than five million users. The site had more than 10 million users in February 2007, and as of July 2010, more than 30 million. This number includes deleted and multiple accounts. In December 2022, Mixi launched an anime brand called MIXI_ANIME. Their first project was an anime short animated by Tatsunoko Production and ZynX, directed by Masami Obari and featuring the vocal performances of Megumi Hayashibara and Kenichi Suzumura, titled Jōkaku Gattai Oshirobots. In 2008, Mixi began "Celebrity Accounts" in which celebrities who are on the social networking site are allowed to surpass the 1000-friend limit and potentially have an unlimited number of followers. Many popular figures have "Celebrity Accounts" such as actress, model, singer Anna Tsuchiya, producer and rapper Shing02, Akihabara idol Haruko Momoi and Lupin III from the self-titled series. In 2011, Mixi announced that it would end "Celebrity Accounts" and replace the function with a new service, "Mixi page". Terms of use In early 2008, Mixi announced a plan to revise their terms of use. The changes, which were supposed to take effect as of April 1, 2008, included a section that appeared to grant Mixi unrestricted ownership to all user generated content. In particular, the proposed changes to Clause 18 stated: "By posting information, including diaries and the like, on this service, users grant the service the unrestricted right to use said information (whether in the form of reproduction, publication, distribution, translation, modification or the like) without compensation." However, the clause was never implemented, apparently due to user protests.[citation needed] The relevant portion of the terms of use currently states that "all rights (including copyright and personal-usage rights) for content belong to the user that created it." In December 2008, Mixi discouraged the use of the site for dating, prohibiting users from "using Mixi mainly to meet with strangers of the other sex". See also References External links |

Contents Computer A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation, or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computers and users. Early computers were meant to be used only for calculations. Simple manual instruments like the abacus have aided people in doing calculations since ancient times. Early in the Industrial Revolution, some mechanical devices were built to automate long, tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analog calculations in the early 20th century. The first digital electronic calculating machines were developed during World War II, both electromechanical and using thermionic valves. The first semiconductor transistors in the late 1940s were followed by the silicon-based MOSFET (MOS transistor) and monolithic integrated circuit chip technologies in the late 1950s, leading to the microprocessor and the microcomputer revolution in the 1970s. The speed, power, and versatility of computers have been increasing dramatically ever since then, with transistor counts increasing at a rapid pace (Moore's law noted that counts doubled every two years), leading to the Digital Revolution during the late 20th and early 21st centuries. Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU) in the form of a microprocessor, together with some type of computer memory, typically semiconductor memory chips. The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices include input devices (keyboards, mice, joysticks, etc.), output devices (monitors, printers, etc.), and input/output devices that perform both functions (e.g. touchscreens). Peripheral devices allow information to be retrieved from an external source, and they enable the results of operations to be saved and retrieved. Etymology It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [sic] read the truest computer of Times, and the best Arithmetician that euer [sic] breathed, and he reduceth thy dayes into a short number." This usage of the term referred to a human computer, a person who carried out calculations or computations. The word continued to have the same meaning until the middle of the 20th century. During the latter part of this period, women were often hired as computers because they could be paid less than their male counterparts. By 1943, most human computers were women. The Online Etymology Dictionary gives the first attested use of computer in the 1640s, meaning 'one who calculates'; this is an "agent noun from compute (v.)". The Online Etymology Dictionary states that the use of the term to mean "'calculating machine' (of any type) is from 1897." The Online Etymology Dictionary indicates that the "modern use" of the term, to mean 'programmable digital electronic computer' dates from "1945 under this name; [in a] theoretical [sense] from 1937, as Turing machine". The name has remained, although modern computers are capable of many higher-level functions. History Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers. The earliest counting device was most likely a form of tally stick. Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres, cones, etc.) which represented counts of items, likely livestock or grains, sealed in hollow unbaked clay containers.[a] The use of counting rods is one example. The abacus was initially used for arithmetic tasks. The Roman abacus was developed from devices used in Babylonia as early as 2400 BCE. Since then, many other forms of reckoning boards or tables have been invented. In a medieval European counting house, a checkered cloth would be placed on a table, and markers moved around on it according to certain rules, as an aid to calculating sums of money. The Antikythera mechanism is believed to be the earliest known mechanical analog computer, according to Derek J. de Solla Price. It was designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to approximately c. 100 BCE. Devices of comparable complexity to the Antikythera mechanism would not reappear until the fourteenth century. Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use. The planisphere was a star chart invented by Abū Rayhān al-Bīrūnī in the early 11th century. The astrolabe was invented in the Hellenistic world in either the 1st or 2nd centuries BCE and is often attributed to Hipparchus. A combination of the planisphere and dioptra, the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer and gear-wheels was invented by Abi Bakr of Isfahan, Persia in 1235. Abū Rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, an early fixed-wired knowledge processing machine with a gear train and gear-wheels, c. 1000 AD. The sector, a calculating instrument used for solving problems in proportion, trigonometry, multiplication and division, and for various functions, such as squares and cube roots, was developed in the late 16th century and found application in gunnery, surveying and navigation. The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. The slide rule was invented around 1620–1630, by the English clergyman William Oughtred, shortly after the publication of the concept of the logarithm. It is a hand-operated analog computer for doing multiplication and division. As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions. Slide rules with special scales are still used for quick performance of routine calculations, such as the E6B circular slide rule used for time and distance calculations on light aircraft. In the 1770s, Pierre Jaquet-Droz, a Swiss watchmaker, built a mechanical doll (automaton) that could write holding a quill pen. By switching the number and order of its internal wheels different letters, and hence different messages, could be produced. In effect, it could be mechanically "programmed" to read instructions. Along with two other complex machines, the doll is at the Musée d'Art et d'Histoire of Neuchâtel, Switzerland, and still operates. In 1831–1835, mathematician and engineer Giovanni Plana devised a Perpetual Calendar machine, which through a system of pulleys and cylinders could predict the perpetual calendar for every year from 0 CE (that is, 1 BCE) to 4000 CE, keeping track of leap years and varying day length. The tide-predicting machine invented by the Scottish scientist Sir William Thomson in 1872 was of great utility to navigation in shallow waters. It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location. The differential analyser, a mechanical analog computer designed to solve differential equations by integration, used wheel-and-disc mechanisms to perform the integration. In 1876, Sir William Thomson had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators. In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Starting in the 1920s, Vannevar Bush and others developed mechanical differential analyzers. In the 1890s, the Spanish engineer Leonardo Torres Quevedo began to develop a series of advanced analog machines that could solve real and complex roots of polynomials, which were published in 1901 by the Paris Academy of Sciences. Charles Babbage, an English mechanical engineer and polymath, originated the concept of a programmable computer. Considered the "father of the computer", he conceptualized and invented the first mechanical computer in the early 19th century. After working on his difference engine he announced his invention in 1822, in a paper to the Royal Astronomical Society, titled "Note on the application of machinery to the computation of astronomical and mathematical tables". He also designed to aid in navigational calculations, in 1833 he realized that a much more general design, an analytical engine, was possible. The input of programs and data was to be provided to the machine via punched cards, a method being used at the time to direct mechanical looms such as the Jacquard loom. For output, the machine would have a printer, a curve plotter and a bell. The machine would also be able to punch numbers onto cards to be read in later. The engine would incorporate an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete. The machine was about a century ahead of its time. All the parts for his machine had to be made by hand – this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with the decision of the British Government to cease funding. Babbage's failure to complete the analytical engine can be chiefly attributed to political and financial difficulties as well as his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow. Nevertheless, his son, Henry Babbage, completed a simplified version of the analytical engine's computing unit (the mill) in 1888. He gave a successful demonstration of its use in computing tables in 1906. In his work Essays on Automatics published in 1914, Leonardo Torres Quevedo wrote a brief history of Babbage's efforts at constructing a mechanical Difference Engine and Analytical Engine. The paper contains a design of a machine capable to calculate formulas like a x ( y − z ) 2 {\displaystyle a^{x}(y-z)^{2}} , for a sequence of sets of values. The whole machine was to be controlled by a read-only program, which was complete with provisions for conditional branching. He also introduced the idea of floating-point arithmetic. In 1920, to celebrate the 100th anniversary of the invention of the arithmometer, Torres presented in Paris the Electromechanical Arithmometer, which allowed a user to input arithmetic problems through a keyboard, and computed and printed the results, demonstrating the feasibility of an electromechanical analytical engine. During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation. However, these were not programmable and generally lacked the versatility and accuracy of modern digital computers. The first modern analog computer was a tide-predicting machine, invented by Sir William Thomson (later to become Lord Kelvin) in 1872. The differential analyser, a mechanical analog computer designed to solve differential equations by integration using wheel-and-disc mechanisms, was conceptualized in 1876 by James Thomson, the elder brother of the more famous Sir William Thomson. The art of mechanical analog computing reached its zenith with the differential analyzer, completed in 1931 by Vannevar Bush at MIT. By the 1950s, the success of digital electronic computers had spelled the end for most analog computing machines, but analog computers remained in use during the 1950s in some specialized applications such as education (slide rule) and aircraft (control systems).[citation needed] Claude Shannon's 1937 master's thesis laid the foundations of digital computing, with his insight of applying Boolean algebra to the analysis and synthesis of switching circuits being the basic concept which underlies all electronic digital computers. By 1938, the United States Navy had developed the Torpedo Data Computer, an electromechanical analog computer for submarines that used trigonometry to solve the problem of firing a torpedo at a moving target. During World War II, similar devices were developed in other countries. Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2, created by German engineer Konrad Zuse in 1939 in Berlin, was one of the earliest examples of an electromechanical relay computer. In 1941, Zuse followed his earlier machine up with the Z3, the world's first working electromechanical programmable, fully automatic digital computer. The Z3 was built with 2000 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. Program code was supplied on punched film while data could be stored in 64 words of memory or supplied from the keyboard. It was quite similar to modern machines in some respects, pioneering numerous advances such as floating-point numbers. Rather than the harder-to-implement decimal system (used in Charles Babbage's earlier design), using a binary system meant that Zuse's machines were easier to build and potentially more reliable, given the technologies available at that time. The Z3 was not itself a universal computer but could be extended to be Turing complete. Zuse's next computer, the Z4, became the world's first commercial computer; after initial delay due to the Second World War, it was completed in 1950 and delivered to the ETH Zurich. The computer was manufactured by Zuse's own company, Zuse KG, which was founded in 1941 as the first company with the sole purpose of developing computers in Berlin. The Z4 served as the inspiration for the construction of the ERMETH, the first Swiss computer and one of the first in Europe. Purely electronic circuit elements soon replaced their mechanical and electromechanical equivalents, at the same time that digital calculation replaced analog. The engineer Tommy Flowers, working at the Post Office Research Station in London in the 1930s, began to explore the possible use of electronics for the telephone exchange. Experimental equipment that he built in 1934 went into operation five years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes. In the US, John Vincent Atanasoff and Clifford E. Berry of Iowa State University developed and tested the Atanasoff–Berry Computer (ABC) in 1942, the first "automatic electronic digital computer". This design was also all-electronic and used about 300 vacuum tubes, with capacitors fixed in a mechanically rotating drum for memory. During World War II, the British code-breakers at Bletchley Park achieved a number of successes at breaking encrypted German military communications. The German encryption machine, Enigma, was first attacked with the help of the electro-mechanical bombes which were often run by women. To crack the more sophisticated German Lorenz SZ 40/42 machine, used for high-level Army communications, Max Newman and his colleagues commissioned Flowers to build the Colossus. He spent eleven months from early February 1943 designing and building the first Colossus. After a functional test in December 1943, Colossus was shipped to Bletchley Park, where it was delivered on 18 January 1944 and attacked its first message on 5 February. Colossus was the world's first electronic digital programmable computer. It used a large number of valves (vacuum tubes). It had paper-tape input and was capable of being configured to perform a variety of boolean logical operations on its data, but it was not Turing-complete. Nine Mk II Colossi were built (The Mk I was converted to a Mk II making ten machines in total). Colossus Mark I contained 1,500 thermionic valves (tubes), but Mark II with 2,400 valves, was both five times faster and simpler to operate than Mark I, greatly speeding the decoding process. The ENIAC (Electronic Numerical Integrator and Computer) was the first electronic programmable computer built in the U.S. Although the ENIAC was similar to the Colossus, it was much faster, more flexible, and it was Turing-complete. Like the Colossus, a "program" on the ENIAC was defined by the states of its patch cables and switches, a far cry from the stored program electronic machines that came later. Once a program was written, it had to be mechanically set into the machine with manual resetting of plugs and switches. The programmers of the ENIAC were six women, often known collectively as the "ENIAC girls". It combined the high speed of electronics with the ability to be programmed for many complex problems. It could add or subtract 5000 times a second, a thousand times faster than any other machine. It also had modules to multiply, divide, and square root. High speed memory was limited to 20 words (about 80 bytes). Built under the direction of John Mauchly and J. Presper Eckert at the University of Pennsylvania, ENIAC's development and construction lasted from 1943 to full operation at the end of 1945. The machine was huge, weighing 30 tons, using 200 kilowatts of electric power and contained over 18,000 vacuum tubes, 1,500 relays, and hundreds of thousands of resistors, capacitors, and inductors. The principle of the modern computer was proposed by Alan Turing in his seminal 1936 paper, On Computable Numbers. Turing proposed a simple device that he called "Universal Computing machine" and that is now known as a universal Turing machine. He proved that such a machine is capable of computing anything that is computable by executing instructions (program) stored on tape, allowing the machine to be programmable. The fundamental concept of Turing's design is the stored program, where all the instructions for computing are stored in memory. Von Neumann acknowledged that the central concept of the modern computer was due to this paper. Turing machines are to this day a central object of study in theory of computation. Except for the limitations imposed by their finite memory stores, modern computers are said to be Turing-complete, which is to say, they have algorithm execution capability equivalent to a universal Turing machine. Early computing machines had fixed programs. Changing its function required the re-wiring and re-structuring of the machine. With the proposal of the stored-program computer this changed. A stored-program computer includes by design an instruction set and can store in memory a set of instructions (a program) that details the computation. The theoretical basis for the stored-program computer was laid out by Alan Turing in his 1936 paper. In 1945, Turing joined the National Physical Laboratory and began work on developing an electronic stored-program digital computer. His 1945 report "Proposed Electronic Calculator" was the first specification for such a device. John von Neumann at the University of Pennsylvania also circulated his First Draft of a Report on the EDVAC in 1945. The Manchester Baby was the world's first stored-program computer. It was built at the University of Manchester in England by Frederic C. Williams, Tom Kilburn and Geoff Tootill, and ran its first program on 21 June 1948. It was designed as a testbed for the Williams tube, the first random-access digital storage device. Although the computer was described as "small and primitive" by a 1998 retrospective, it was the first working machine to contain all of the elements essential to a modern electronic computer. As soon as the Baby had demonstrated the feasibility of its design, a project began at the university to develop it into a practically useful computer, the Manchester Mark 1. The Mark 1 in turn quickly became the prototype for the Ferranti Mark 1, the world's first commercially available general-purpose computer. Built by Ferranti, it was delivered to the University of Manchester in February 1951. At least seven of these later machines were delivered between 1953 and 1957, one of them to Shell labs in Amsterdam. In October 1947 the directors of British catering company J. Lyons & Company decided to take an active role in promoting the commercial development of computers. Lyons's LEO I computer, modelled closely on the Cambridge EDSAC of 1949, became operational in April 1951 and ran the world's first routine office computer job. The concept of a field-effect transistor was proposed by Julius Edgar Lilienfeld in 1925. John Bardeen and Walter Brattain, while working under William Shockley at Bell Labs, built the first working transistor, the point-contact transistor, in 1947, which was followed by Shockley's bipolar junction transistor in 1948. From 1955 onwards, transistors replaced vacuum tubes in computer designs, giving rise to the "second generation" of computers. Compared to vacuum tubes, transistors have many advantages: they are smaller, and require less power than vacuum tubes, so give off less heat. Junction transistors were much more reliable than vacuum tubes and had longer, indefinite, service life. Transistorized computers could contain tens of thousands of binary logic circuits in a relatively compact space. However, early junction transistors were relatively bulky devices that were difficult to manufacture on a mass-production basis, which limited them to a number of specialized applications. At the University of Manchester, a team under the leadership of Tom Kilburn designed and built a machine using the newly developed transistors instead of valves. Their first transistorized computer and the first in the world, was operational by 1953, and a second version was completed there in April 1955. However, the machine did make use of valves to generate its 125 kHz clock waveforms and in the circuitry to read and write on its magnetic drum memory, so it was not the first completely transistorized computer. That distinction goes to the Harwell CADET of 1955, built by the electronics division of the Atomic Energy Research Establishment at Harwell. The metal–oxide–silicon field-effect transistor (MOSFET), also known as the MOS transistor, was invented at Bell Labs between 1955 and 1960 and was the first truly compact transistor that could be miniaturized and mass-produced for a wide range of uses. With its high scalability, and much lower power consumption and higher density than bipolar junction transistors, the MOSFET made it possible to build high-density integrated circuits. In addition to data processing, it also enabled the practical use of MOS transistors as memory cell storage elements, leading to the development of MOS semiconductor memory, which replaced earlier magnetic-core memory in computers. The MOSFET led to the microcomputer revolution, and became the driving force behind the computer revolution. The MOSFET is the most widely used transistor in computers, and is the fundamental building block of digital electronics. The next great advance in computing power came with the advent of the integrated circuit (IC). The idea of the integrated circuit was first conceived by a radar scientist working for the Royal Radar Establishment of the Ministry of Defence, Geoffrey W.A. Dummer. Dummer presented the first public description of an integrated circuit at the Symposium on Progress in Quality Electronic Components in Washington, D.C., on 7 May 1952. The first working ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". However, Kilby's invention was a hybrid integrated circuit (hybrid IC), rather than a monolithic integrated circuit (IC) chip. Kilby's IC had external wire connections, which made it difficult to mass-produce. Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. Noyce's invention was the first true monolithic IC chip. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium. Noyce's monolithic IC was fabricated using the planar process, developed by his colleague Jean Hoerni in early 1959. In turn, the planar process was based on Carl Frosch and Lincoln Derick work on semiconductor surface passivation by silicon dioxide. Modern monolithic ICs are predominantly MOS (metal–oxide–semiconductor) integrated circuits, built from MOSFETs (MOS transistors). The earliest experimental MOS IC to be fabricated was a 16-transistor chip built by Fred Heiman and Steven Hofstein at RCA in 1962. General Microelectronics later introduced the first commercial MOS IC in 1964, developed by Robert Norman. Following the development of the self-aligned gate (silicon-gate) MOS transistor by Robert Kerwin, Donald Klein and John Sarace at Bell Labs in 1967, the first silicon-gate MOS IC with self-aligned gates was developed by Federico Faggin at Fairchild Semiconductor in 1968. The MOSFET has since become the most critical device component in modern ICs. The development of the MOS integrated circuit led to the invention of the microprocessor, and heralded an explosion in the commercial and personal use of computers. While the subject of exactly which device was the first microprocessor is contentious, partly due to lack of agreement on the exact definition of the term "microprocessor", it is largely undisputed that the first single-chip microprocessor was the Intel 4004, designed and realized by Federico Faggin with his silicon-gate MOS IC technology, along with Ted Hoff, Masatoshi Shima and Stanley Mazor at Intel.[b] In the early 1970s, MOS IC technology enabled the integration of more than 10,000 transistors on a single chip. System on a Chip (SoCs) are complete computers on a microchip (or chip) the size of a coin. They may or may not have integrated RAM and flash memory. If not integrated, the RAM is usually placed directly above (known as Package on package) or below (on the opposite side of the circuit board) the SoC, and the flash memory is usually placed right next to the SoC. This is done to improve data transfer speeds, as the data signals do not have to travel long distances. Since ENIAC in 1945, computers have advanced enormously, with modern SoCs (such as the Snapdragon 865) being the size of a coin while also being hundreds of thousands of times more powerful than ENIAC, integrating billions of transistors, and consuming only a few watts of power. The first mobile computers were heavy and ran from mains power. The 50 lb (23 kg) IBM 5100 was an early example. Later portables such as the Osborne 1 and Compaq Portable were considerably lighter but still needed to be plugged in. The first laptops, such as the Grid Compass, removed this requirement by incorporating batteries – and with the continued miniaturization of computing resources and advancements in portable battery life, portable computers grew in popularity in the 2000s. The same developments allowed manufacturers to integrate computing resources into cellular mobile phones by the early 2000s. These smartphones and tablets run on a variety of operating systems and recently became the dominant computing device on the market. These are powered by System on a Chip (SoCs), which are complete computers on a microchip the size of a coin. Types Computers can be classified in a number of different ways, including: A computer does not need to be electronic, nor even have a processor, nor RAM, nor even a hard disk. While popular usage of the word "computer" is synonymous with a personal electronic computer,[c] a typical modern definition of a computer is: "A device that computes, especially a programmable [usually] electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information." According to this definition, any device that processes information qualifies as a computer. Hardware The term hardware covers all of those parts of a computer that are tangible physical objects. Circuits, computer chips, graphic cards, sound cards, memory (RAM), motherboard, displays, power supplies, cables, keyboards, printers and "mice" input devices are all hardware. A general-purpose computer has four main components: the arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by buses, often made of groups of wires. Inside each of these parts are thousands to trillions of small electrical circuits which can be turned off or on by means of an electronic switch. Each circuit represents a bit (binary digit) of information so that when the circuit is on it represents a "1", and when off it represents a "0" (in positive logic representation). The circuits are arranged in logic gates so that one or more of the circuits may control the state of one or more of the other circuits. Input devices are the means by which the operations of a computer are controlled and it is provided with data. Examples include: Output devices are the means by which a computer provides the results of its calculations in a human-accessible form. Examples include: The control unit (often called a control system or central controller) manages the computer's various components; it reads and interprets (decodes) the program instructions, transforming them into control signals that activate other parts of the computer.[e] Control systems in advanced computers may change the order of execution of some instructions to improve performance. A key component common to all CPUs is the program counter, a special memory cell (a register) that keeps track of which location in memory the next instruction is to be read from.[f] The control system's function is as follows— this is a simplified description, and some of these steps may be performed concurrently or in a different order depending on the type of CPU: Since the program counter is (conceptually) just another set of memory cells, it can be changed by calculations done in the ALU. Adding 100 to the program counter would cause the next instruction to be read from a place 100 locations further down the program. Instructions that modify the program counter are often known as "jumps" and allow for loops (instructions that are repeated by the computer) and often conditional instruction execution (both examples of control flow). The sequence of operations that the control unit goes through to process an instruction is in itself like a short computer program, and indeed, in some more complex CPU designs, there is another yet smaller computer called a microsequencer, which runs a microcode program that causes all of these events to happen. The control unit, ALU, and registers are collectively known as a central processing unit (CPU). Early CPUs were composed of many separate components. Since the 1970s, CPUs have typically been constructed on a single MOS integrated circuit chip called a microprocessor. The ALU is capable of performing two classes of operations: arithmetic and logic. The set of arithmetic operations that a particular ALU supports may be limited to addition and subtraction, or might include multiplication, division, trigonometry functions such as sine, cosine, etc., and square roots. Some can operate only on whole numbers (integers) while others use floating point to represent real numbers, albeit with limited precision. However, any computer that is capable of performing just the simplest operations can be programmed to break down the more complex operations into simple steps that it can perform. Therefore, any computer can be programmed to perform any arithmetic operation—although it will take more time to do so if its ALU does not directly support the operation. An ALU may also compare numbers and return Boolean truth values (true or false) depending on whether one is equal to, greater than or less than the other ("is 64 greater than 65?"). Logic operations involve Boolean logic: AND, OR, XOR, and NOT. These can be useful for creating complicated conditional statements and processing Boolean logic. Superscalar computers may contain multiple ALUs, allowing them to process several instructions simultaneously. Graphics processors and computers with SIMD and MIMD features often contain ALUs that can perform arithmetic on vectors and matrices. A computer's memory can be viewed as a list of cells into which numbers can be placed or read. Each cell has a numbered "address" and can store a single number. The computer can be instructed to "put the number 123 into the cell numbered 1357" or to "add the number that is in cell 1357 to the number that is in cell 2468 and put the answer into cell 1595." The information stored in memory may represent practically anything. Letters, numbers, even computer instructions can be placed into memory with equal ease. Since the CPU does not differentiate between different types of information, it is the software's responsibility to give significance to what the memory sees as nothing but a series of numbers. In almost all modern computers, each memory cell is set up to store binary numbers in groups of eight bits (called a byte). Each byte is able to represent 256 different numbers (28 = 256); either from 0 to 255 or −128 to +127. To store larger numbers, several consecutive bytes may be used (typically, two, four or eight). When negative numbers are required, they are usually stored in two's complement notation. Other arrangements are possible, but are usually not seen outside of specialized applications or historical contexts. A computer can store any kind of information in memory if it can be represented numerically. Modern computers have billions or even trillions of bytes of memory. The CPU contains a special set of memory cells called registers that can be read and written to much more rapidly than the main memory area. There are typically between two and one hundred registers depending on the type of CPU. Registers are used for the most frequently needed data items to avoid having to access main memory every time data is needed. As data is constantly being worked on, reducing the need to access main memory (which is often slow compared to the ALU and control units) greatly increases the computer's speed. Computer main memory comes in two principal varieties: RAM can be read and written to anytime the CPU commands it, but ROM is preloaded with data and software that never changes, therefore the CPU can only read from it. ROM is typically used to store the computer's initial start-up instructions. In general, the contents of RAM are erased when the power to the computer is turned off, but ROM retains its data indefinitely. In a PC, the ROM contains a specialized program called the BIOS that orchestrates loading the computer's operating system from the hard disk drive into RAM whenever the computer is turned on or reset. In embedded computers, which frequently do not have disk drives, all of the required software may be stored in ROM. Software stored in ROM is often called firmware, because it is notionally more like hardware than software. Flash memory blurs the distinction between ROM and RAM, as it retains its data when turned off but is also rewritable. It is typically much slower than conventional ROM and RAM however, so its use is restricted to applications where high speed is unnecessary.[g] In more sophisticated computers there may be one or more RAM cache memories, which are slower than registers but faster than main memory. Generally computers with this sort of cache are designed to move frequently needed data into the cache automatically, often without the need for any intervention on the programmer's part. I/O is the means by which a computer exchanges information with the outside world. Devices that provide input or output to the computer are called peripherals. On a typical personal computer, peripherals include input devices like the keyboard and mouse, and output devices such as the display and printer. Hard disk drives, floppy disk drives and optical disc drives serve as both input and output devices. Computer networking is another form of I/O. I/O devices are often complex computers in their own right, with their own CPU and memory. A graphics processing unit might contain fifty or more tiny computers that perform the calculations necessary to display 3D graphics.[citation needed] Modern desktop computers contain many smaller computers that assist the main CPU in performing I/O. A 2016-era flat screen display contains its own computer circuitry. While a computer may be viewed as running one gigantic program stored in its main memory, in some systems it is necessary to give the appearance of running several programs simultaneously. This is achieved by multitasking, i.e. having the computer switch rapidly between running each program in turn. One means by which this is done is with a special signal called an interrupt, which can periodically cause the computer to stop executing instructions where it was and do something else instead. By remembering where it was executing prior to the interrupt, the computer can return to that task later. If several programs are running "at the same time". Then the interrupt generator might be causing several hundred interrupts per second, causing a program switch each time. Since modern computers typically execute instructions several orders of magnitude faster than human perception, it may appear that many programs are running at the same time, even though only one is ever executing in any given instant. This method of multitasking is sometimes termed "time-sharing" since each program is allocated a "slice" of time in turn. Before the era of inexpensive computers, the principal use for multitasking was to allow many people to share the same computer. Seemingly, multitasking would cause a computer that is switching between several programs to run more slowly, in direct proportion to the number of programs it is running, but most programs spend much of their time waiting for slow input/output devices to complete their tasks. If a program is waiting for the user to click on the mouse or press a key on the keyboard, then it will not take a "time slice" until the event it is waiting for has occurred. This frees up time for other programs to execute so that many programs may be run simultaneously without unacceptable speed loss. Some computers are designed to distribute their work across several CPUs in a multiprocessing configuration, a technique once employed in only large and powerful machines such as supercomputers, mainframe computers and servers. Multiprocessor and multi-core (multiple CPUs on a single integrated circuit) personal and laptop computers are now widely available, and are being increasingly used in lower-end markets as a result. Supercomputers in particular often have highly unique architectures that differ significantly from the basic stored-program architecture and from general-purpose computers.[h] They often feature thousands of CPUs, customized high-speed interconnects, and specialized computing hardware. Such designs tend to be useful for only specialized tasks due to the large scale of program organization required to use most of the available resources at once. Supercomputers usually see usage in large-scale simulation, graphics rendering, and cryptography applications, as well as with other so-called "embarrassingly parallel" tasks. Software Software is the part of a computer system that consists of the encoded information that determines the computer's operation, such as data or instructions on how to process the data. In contrast to the physical hardware from which the system is built, software is immaterial. Software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. It is often divided into system software and application software. Computer hardware and software require each other and neither is useful on its own. When software is stored in hardware that cannot easily be modified, such as with BIOS ROM in an IBM PC compatible computer, it is sometimes called "firmware". The defining feature of modern computers which distinguishes them from all other machines is that they can be programmed. That is to say that some type of instructions (the program) can be given to the computer, and it will process them. Modern computers based on the von Neumann architecture often have machine code in the form of an imperative programming language. In practical terms, a computer program may be just a few instructions or extend to many millions of instructions, as do the programs for word processors and web browsers for example. A typical modern computer can execute billions of instructions per second (gigaflops) and rarely makes a mistake over many years of operation. Large computer programs consisting of several million instructions may take teams of programmers years to write, and due to the complexity of the task almost certainly contain errors. This section applies to most common RAM machine–based computers. In most cases, computer instructions are simple: add one number to another, move some data from one location to another, send a message to some external device, etc. These instructions are read from the computer's memory and are generally carried out (executed) in the order they were given. However, there are usually specialized instructions to tell the computer to jump ahead or backwards to some other place in the program and to carry on executing from there. These are called "jump" instructions (or branches). Furthermore, jump instructions may be made to happen conditionally so that different sequences of instructions may be used depending on the result of some previous calculation or some external event. Many computers directly support subroutines by providing a type of jump that "remembers" the location it jumped from and another instruction to return to the instruction following that jump instruction. Program execution might be likened to reading a book. While a person will normally read each word and line in sequence, they may at times jump back to an earlier place in the text or skip sections that are not of interest. Similarly, a computer may sometimes go back and repeat the instructions in some section of the program over and over again until some internal condition is met. This is called the flow of control within the program and it is what allows the computer to perform tasks repeatedly without human intervention. Comparatively, a person using a pocket calculator can perform a basic arithmetic operation such as adding two numbers with just a few button presses. But to add together all of the numbers from 1 to 1,000 would take thousands of button presses and a lot of time, with a near certainty of making a mistake. On the other hand, a computer may be programmed to do this with just a few simple instructions. The following example is written in the MIPS assembly language: Once told to run this program, the computer will perform the repetitive addition task without further human intervention. It will almost never make a mistake and a modern PC can complete the task in a fraction of a second. In most computers, individual instructions are stored as machine code with each instruction being given a unique number (its operation code or opcode for short). The command to add two numbers together would have one opcode; the command to multiply them would have a different opcode, and so on. The simplest computers are able to perform any of a handful of different instructions; the more complex computers have several hundred to choose from, each with a unique numerical code. Since the computer's memory is able to store numbers, it can also store the instruction codes. This leads to the important fact that entire programs (which are just lists of these instructions) can be represented as lists of numbers and can themselves be manipulated inside the computer in the same way as numeric data. The fundamental concept of storing programs in the computer's memory alongside the data they operate on is the crux of the von Neumann, or stored program, architecture. In some cases, a computer might store some or all of its program in memory that is kept separate from the data it operates on. This is called the Harvard architecture after the Harvard Mark I computer. Modern von Neumann computers display some traits of the Harvard architecture in their designs, such as in CPU caches. While it is possible to write computer programs as long lists of numbers (machine language) and while this technique was used with many early computers,[i] it is extremely tedious and potentially error-prone to do so in practice, especially for complicated programs. Instead, each basic instruction can be given a short name that is indicative of its function and easy to remember – a mnemonic such as ADD, SUB, MULT or JUMP. These mnemonics are collectively known as a computer's assembly language. Converting programs written in assembly language into something the computer can actually understand (machine language) is usually done by a computer program called an assembler. A programming language is a notation system for writing the source code from which a computer program is produced. Programming languages provide various ways of specifying programs for computers to run. Unlike natural languages, programming languages are designed to permit no ambiguity and to be concise. They are purely written languages and are often difficult to read aloud. They are generally either translated into machine code by a compiler or an assembler before being run, or translated directly at run time by an interpreter. Sometimes programs are executed by a hybrid method of the two techniques. There are thousands of programming languages—some intended for general purpose programming, others useful for only highly specialized applications. Machine languages and the assembly languages that represent them (collectively termed low-level programming languages) are generally unique to the particular architecture of a computer's central processing unit (CPU). For instance, an ARM architecture CPU (such as may be found in a smartphone or a hand-held videogame) cannot understand the machine language of an x86 CPU that might be in a PC.[j] Historically a significant number of other CPU architectures were created and saw extensive use, notably including the MOS Technology 6502 and 6510 in addition to the Zilog Z80. Although considerably easier than in machine language, writing long programs in assembly language is often difficult and is also error prone. Therefore, most practical programs are written in more abstract high-level programming languages that are able to express the needs of the programmer more conveniently (and thereby help reduce programmer error). High level languages are usually "compiled" into machine language (or sometimes into assembly language and then into machine language) using another computer program called a compiler.[k] High level languages are less related to the workings of the target computer than assembly language, and more related to the language and structure of the problem(s) to be solved by the final program. It is therefore often possible to use different compilers to translate the same high level language program into the machine language of many different types of computer. This is part of the means by which software like video games may be made available for different computer architectures such as personal computers and various video game consoles. Program design of small programs is relatively simple and involves the analysis of the problem, collection of inputs, using the programming constructs within languages, devising or using established procedures and algorithms, providing data for output devices and solutions to the problem as applicable. As problems become larger and more complex, features such as subprograms, modules, formal documentation, and new paradigms such as object-oriented programming are encountered. Large programs involving thousands of line of code and more require formal software methodologies. The task of developing large software systems presents a significant intellectual challenge. Producing software with an acceptably high reliability within a predictable schedule and budget has historically been difficult; the academic and professional discipline of software engineering concentrates specifically on this challenge. Errors in computer programs are called "bugs". They may be benign and not affect the usefulness of the program, or have only subtle effects. However, in some cases they may cause the program or the entire system to "hang", becoming unresponsive to input such as mouse clicks or keystrokes, to completely fail, or to crash. Otherwise benign bugs may sometimes be harnessed for malicious intent by an unscrupulous user writing an exploit, code designed to take advantage of a bug and disrupt a computer's proper execution. Bugs are usually not the fault of the computer. Since computers merely execute the instructions they are given, bugs are nearly always the result of programmer error or an oversight made in the program's design.[l] Admiral Grace Hopper, an American computer scientist and developer of the first compiler, is credited for having first used the term "bugs" in computing after a dead moth was found shorting a relay in the Harvard Mark II computer in September 1947. Networking and the Internet Computers have been used to coordinate information between multiple physical locations since the 1950s. The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems such as Sabre. In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology. The effort was funded by ARPA (now DARPA), and the computer network that resulted was called the ARPANET. Logic gates are a common abstraction which can apply to most of the above digital or analog paradigms. The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a minimum capability (being Turing-complete) is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, any type of computer (netbook, supercomputer, cellular automaton, etc.) is able to perform the same computational tasks, given enough time and storage capacity. In the 20th century, artificial intelligence systems were predominantly symbolic: they executed code that was explicitly programmed by software developers. Machine learning models, however, have a set parameters that are adjusted throughout training, so that the model learns to accomplish a task based on the provided data. The efficiency of machine learning (and in particular of neural networks) has rapidly improved with progress in hardware for parallel computing, mainly graphics processing units (GPUs). Some large language models are able to control computers or robots. AI progress may lead to the creation of artificial general intelligence (AGI), a type of AI that could accomplish virtually any intellectual task at least as well as humans. Professions and organizations As the use of computers has spread throughout society, there are an increasing number of careers involving computers. The need for computers to work well together and to be able to exchange information has spawned the need for many standards organizations, clubs and societies of both a formal and informal nature.

Contents Misskey Misskey (Japanese: ミスキー, romanized: Misukī) is an open source, federated, social networking service created in 2014 by Japanese software engineer Eiji "syuilo" Shinoda. Misskey uses the ActivityPub protocol for federation, allowing users to interact between independent Misskey instances, and other ActivityPub compatible platforms. Misskey is generally considered to be part of the Fediverse. Despite being a decentralized service, Misskey is not philosophically opposed to centralization. The name Misskey comes from the lyrics of Brain Diver, a song by the Japanese singer May'n. History Misskey was initially developed as a BBS-style internet forum by high school student Eiji Shinoda in 2014. After introducing a timeline feature, Misskey gained popularity as the microblogging platform it is today.[citation needed] In 2018, Misskey added support for ActivityPub, becoming a federated social media platform. The flagship Misskey server, Misskey.io, was started on April 15, 2019.[citation needed] Misskey, alongside Mastodon and Bluesky, has received attention as a potential replacement for Twitter following Twitter's acquisition by Elon Musk in 2022. On April 8, 2023, Misskey.io incorporated as MisskeyHQ K.K. As of February 2024, over 450,000 users were registered, making it the largest instance of Misskey. Misskey.io is crowdfunded. The administrator of Misskey.io is Japanese system administrator Yoshiki Eto, who operates under the alias Murakami-san. Eiji Shinoda serves as director. In July 2023, Twitter introduced extreme restrictions on their API in order to combat scraping from bots. Some users were critical of the changes, and as a result migrated to other social networks. The number of users registering on Misskey.io, Misskey's official instance and the largest one, increased rapidly, with other Misskey instances also receiving a spike in signups. In response to this trend, Skeb [ja], a platform for sharing art, announced on July 14, 2023 that it would sponsor the Misskey development team. In early 2024, Misskey was targeted by a spam attack from Japan. The cause of the attack is believed to be a dispute between rival groups on a Japanese hacker forum and a DDoS attack on a Discord bot. Mastodon instances with open registration were used in the attack. In November 2025, the flagship instance Misskey.io is expected to replace ActivityPub with their own low-overhead federation system. Development Misskey is open source software and is licensed under the AGPLv3. The Misskey API is publicly available and is documented using the OpenAPI Specification, which allows users to build automated accounts and use it on any Misskey instance.[citation needed] The service is translated using Crowdin. Misskey is developed using Node.js. TypeScript is used on both the frontend and backend. PostgreSQL is used as its database. Vue.js is used for the frontend. Functionality Posts on Misskey are called "notes". Notes are limited to a maximum of 3,000 characters (a limit which can be customized by instances), and can be accompanied by any file, including polls, images, videos, and audio. Notes can be reposted, either by themselves or with another "quote" note. Misskey comes with multiple timelines to sort through the notes that an instance has available, and are displayed in reverse chronological order. The Home timeline shows notes from users that you follow, the Local timeline shows all notes from the instance in use, the Social timeline shows both the Home and Local timeline, and the Global timeline shows every public note that the instance knows about.[citation needed] Notes have customizable privacy settings to control what users can see a note, similar to Mastodon's post visibility ranges. Public notes show up on all timelines, while Home notes only show on a user's Home timeline. Notes can also be set to be available only for followers. Direct messages using notes can be sent to users.[citation needed] See also References and notes External links |

Contents Cambridge Philosophical Society The Cambridge Philosophical Society (CPS) is a scientific society at the University of Cambridge. It was founded in 1819. The name derives from the medieval use of the word philosophy to denote any research undertaken outside the fields of law, theology and medicine. The society was granted a royal charter by King William IV in 1832. The society is governed by an elected council of senior academics, which is chaired by the Society's President, according to a set of statutes. The society has published several scientific journals, including Biological Reviews (established 1926) and Mathematical Proceedings of the Cambridge Philosophical Society (formerly entitled Proceedings of the Cambridge Philosophical Society, published since 1843). Transactions of the Cambridge Philosophical Society was published between 1821–1928, but was then discontinued. History The society was founded in 1819 by John Stevens Henslow, Adam Sedgwick and Edward Clarke, is Cambridge's oldest scientific society. Its prime purpose is to "keep alive the spirit of inquiry". For over 200 years, this spirit has been kept alive by its members and its activities. The society is independent of the University of Cambridge, although its offices are located within the University of Cambridge estate in central Cambridge. The Society has provided an open forum and played a key role in raising the profile of the sciences to the public. The society is a registered charity: 213811 and has 11 Trustees. It is assisted by a number of full-time and part-time paid staff. Membership of the Society is currently over 2,000. William Bate Hardy Prize and the William Hopkins Prize The Society awards a number of prizes for new publications, inventions, investigations or discoveries in the fields of mathematics, physics and the natural sciences. Awards given are the William Bate Hardy Prize and The William Hopkins Prize. The William Hopkins Prize was established in 1862 and is one of the oldest scientific prizes at the University of Cambridge. Past recipients of the prize include James Clerk Maxwell, Lord Rayleigh, Sir G. G. Stokes, Sir J. D. Cockcroft, Sir A. S. Eddington, Paul Dirac and Stephen Hawking. Fellow of the Cambridge Philosophical Society (F.C.P.S.) Members of the Society are called Fellows and are entitled to use the ‘FCPS’ post-nominals. Fellows are usually academics or graduate students involved in mathematical or scientific research within the university. A Fellow must be recommended in writing by both a Fellow of the Society who has been a member for at least three years and a person of appropriate standing, who knows the candidate in a professional capacity. Approved candidates are elected at open meetings of the Society following proposal at Council Meetings. Journals The society publishes one of the oldest mathematical journals in history: "Mathematical Proceedings" first published in 1843 and now published for Cambridge Philosophical Society by Cambridge University Press. It has also published "Biological Reviews" since 1926. Lectures The society organizes lectures given by prominent scientists and mathematicians. The lectures are free and open to all who are interested to attend. Nobel laureates The Society has had numerous Fellows and Honorary Fellows who have been awarded the Nobel Prize. The first two recipients were Honorary Fellows Hendrik A Lorentz and Pieter Zeeman in 1902 for the Nobel Prize in Physics. The Society's first women winner was Honorary Fellow Marie Curie in 1903 for the Nobel Prize in Physics. Marie Curie was the first person to win or share two Nobel Prizes, being awarded the Nobel Prize in Chemistry in 1911. In 1964, Dorothy Hodgkin became not only the first female Fellow of the Society to win a Nobel Prize (Chemistry) but also the first female member of the University of Cambridge to do so. Currently 52 Nobel Prize winners are listed amongst its Fellows and Honorary Fellows of the Cambridge Philosophical Society. Notable Fellows Blue Plaque To commemorate the Society’s bicentenary, a blue plaque to the Society was erected in March 2019 on 2 All Saints Passage (the house built by the Society in 1833 to house its meeting room, library and collections). The plaque was unveiled by Sir Martin Rees at opening of the Society’s exhibition at Cambridge University Library. Society Archives The society has built up an exceptional historical scientific record dating back to 1819. While not on public display, the archives can be viewed by prior arrangement with the Cambridge Philosophical Society. The Society archives include the following: Charles Darwin: Extracts from Letters to Henslow Charles Darwin, a student at Christ's College, University of Cambridge, came to know John Stevens Henslow as his tutor and through his attendance at Henslow's scientific talks at the university. Darwin had been recommended by Henslow to take his place aboard the survey ship HMS Beagle on a two-year voyage to survey South America, which eventually lasted five years and circumnavigated the globe. During the voyage, Darwin corresponded by letter with Henslow after reaching South America, and collected specimens with him in mind, particularly plants. Extracts from ten of Darwin's letters from South America to Henslow were first read out at a meeting of the Cambridge Philosophical Society on 16 November 1835, around the time that the ship reached Tahiti. Two days later, Adam Sedgwick read geological notes based on the letters to the Geological Society of London. The Council of the Cambridge Philosophical Society had the extracts printed in a pamphlet dated 1 December 1835, for private distribution among the Members of the Society,. The pamphlet has been described as the first writing of Charles Darwin ever to be published, but earlier, while still at Cambridge University, he had his notes on insects published in a book by James Francis Stephens. The readings were held and the pamphlet Extracts from Letters to Henslow was printed without Darwin's knowledge. Upon learning of this pamphlet, Darwin was "a good deal horrified" at Henslow making public "what had been written without care or accuracy". The publicity helped Darwin's career, and at the end of his life acknowledged their friendship as the most important "circumstance" of his life. The original pamphlet is now rare. According to American Book Prices Current only four copies have appeared at auction since 1975. On 19 June 2014 Christies auctioned an original copy in New York (Sale 2861) and realised $221,000. In 1960 it was reprinted privately to mark the 100th anniversary of the publication of the "Origin of Species" on 26 November 1859 and issued to Members and Associates of the Society.

Contents The New York Times The New York Times (NYT)[b] is a newspaper based in Manhattan, New York City. The New York Times covers domestic, national, and international news, and publishes opinion pieces and reviews. As one of the longest-running newspapers in the United States, the Times serves as one of the country's newspapers of record. As of August 2025[update], The New York Times had 11.88 million total and 11.3 million online subscribers, both by significant margins the highest numbers for any newspaper in the United States; the total also included 580,000 print subscribers. The New York Times is published by the New York Times Company; since 1896, the company has been chaired by the Ochs-Sulzberger family, whose current chairman and the paper's publisher is A. G. Sulzberger. The Times is headquartered at The New York Times Building in Midtown Manhattan. The Times was founded as the conservative New-York Daily Times in 1851, and came to national recognition in the 1870s with its aggressive coverage of corrupt politician Boss Tweed. Following the Panic of 1893, Chattanooga Times publisher Adolph Ochs gained a controlling interest in the company. In 1935, Ochs was succeeded by his son-in-law, Arthur Hays Sulzberger, who began a push into European news. Sulzberger's son Arthur Ochs Sulzberger became publisher in 1963, adapting to a changing newspaper industry and introducing radical changes. The New York Times was involved in the landmark 1964 U.S. Supreme Court case New York Times Co. v. Sullivan, which restricted the ability of public officials to sue the media for defamation. In 1971, The New York Times published the Pentagon Papers, an internal Department of Defense document detailing the United States's historical involvement in the Vietnam War, despite pushback from then-president Richard Nixon. In the landmark decision New York Times Co. v. United States (1971), the Supreme Court ruled that the First Amendment guaranteed the right to publish the Pentagon Papers. In the 1980s, the Times began a two-decade progression to digital technology and launched nytimes.com in 1996. In the 21st century, it shifted its publication online amid the global decline of newspapers. Currently, the Times maintains several regional bureaus staffed with journalists across six continents. It has expanded to several other publications, including The New York Times Magazine, The New York Times International Edition, and The New York Times Book Review. In addition, the paper has produced several television series, podcasts—including The Daily—and games through The New York Times Games. The New York Times has been involved in a number of controversies in its history. Among other accolades, it has been awarded the Pulitzer Prize 135 times since 1918, the most of any publication. According to a 2025 Pew Research Center study on educational differences among audiences of 30 major U.S. news outlets, The New York Times had the highest proportion of college-educated readers among the daily newspapers surveyed, with 56% of its audience holding at least a bachelor's degree. History The New York Times was established in 1851 as the New-York Daily Times by New-York Tribune journalists Henry Jarvis Raymond and George Jones. The Times experienced significant circulation, particularly among conservatives; New-York Tribune publisher Horace Greeley praised the Times. During the American Civil War, Times correspondents gathered information directly from Confederate states. In 1869, Jones inherited the paper from Raymond, who had changed its name to The New-York Times. Under Jones, the Times began to publish a series of articles criticizing Tammany Hall political boss William M. Tweed, despite vehement opposition from other New York newspapers. In 1871, The New-York Times published Tammany Hall's accounting books; Tweed was tried in 1873 and sentenced to twelve years in prison. The Times earned national recognition for its coverage of Tweed. In 1891, Jones died, creating a management imbroglio in which his children had insufficient business acumen to inherit the company and his will prevented an acquisition of the Times. Editor-in-chief Charles Ransom Miller, editorial editor Edward Cary, and correspondent George F. Spinney established a company to manage The New-York Times, but faced financial difficulties during the Panic of 1893. In August 1896, Chattanooga Times publisher Adolph Ochs acquired The New-York Times, implementing significant alterations to the newspaper's structure. Ochs established the Times as a merchant's newspaper and removed the hyphen from the newspaper's name. In 1905, The New York Times opened Times Tower, marking expansion. The Times experienced a political realignment in the 1910s amid several disagreements within the Republican Party. The New York Times reported on the sinking of the Titanic, as other newspapers were cautious about bulletins circulated by the Associated Press. Through managing editor Carr Van Anda, the Times paid considerable attention to advances in science, reporting on Albert Einstein's then-obscure theory of general relativity and becoming involved in the discovery of the tomb of Tutankhamun. In April 1935, Ochs died, leaving his son-in-law Arthur Hays Sulzberger as publisher. The Great Depression forced Sulzberger to reduce The New York Times's operations, and developments in the New York newspaper landscape resulted in the formation of larger newspapers, such as the New York Herald Tribune and the New York World-Telegram. In contrast to Ochs, Sulzberger encouraged wirephotography. The New York Times extensively covered World War II through large headlines, reporting on exclusive stories such as the Yugoslav coup d'état. Amid the war, Sulzberger began expanding the Times's operations further, acquiring WQXR-FM in 1944—the first non-Times investment since the Jones era—and established a fashion show in Times Hall. Despite reductions as a result of conscription, The New York Times retained the largest journalism staff of any newspaper. The Times's print edition became available internationally during the war through the Army & Air Force Exchange Service; The New York Times Overseas Weekly later became available in Japan through The Asahi Shimbun and in Germany through the Frankfurter Zeitung. The international edition would develop into a separate newspaper. Journalist William L. Laurence publicized the atomic bomb race between the United States and Germany, resulting in the Federal Bureau of Investigation seizing copies of the Times. The United States government recruited Laurence to document the Manhattan Project in April 1945. Laurence became the only witness of the Manhattan Project, a detail realized by employees of The New York Times following the atomic bombing of Hiroshima. Following World War II, The New York Times continued to expand. The Times was subject to investigations from the Senate Internal Security Subcommittee, a McCarthyist subcommittee that investigated purported communism from within press institutions. Arthur Hays Sulzberger's decision to dismiss a copyreader who had pleaded the Fifth Amendment drew ire from within the Times and from external organizations. In April 1961, Sulzberger resigned, appointing his son-in-law, The New York Times Company president Orvil Dryfoos. Under Dryfoos, The New York Times established a newspaper based in Los Angeles. In 1962, the implementation of automated printing presses in response to increasing costs mounted fears over technological unemployment. The New York Typographical Union staged a strike in December, altering the media consumption of New Yorkers. The strike left New York with three remaining newspapers—the Times, the Daily News, and the New York Post—by its conclusion in March 1963. In May, Dryfoos died of a heart ailment. Following weeks of ambiguity, Arthur Ochs Sulzberger became The New York Times's publisher. Technological advancements leveraged by newspapers such as the Los Angeles Times and improvements in coverage from The Washington Post and The Wall Street Journal necessitated adaptations to nascent computing. The New York Times published "Heed Their Rising Voices" in 1960, a full-page advertisement purchased by supporters of Martin Luther King Jr. criticizing law enforcement in Montgomery, Alabama for their response to the civil rights movement. Montgomery Public Safety commissioner L. B. Sullivan sued the Times for defamation. In New York Times Co. v. Sullivan (1964), the U.S. Supreme Court ruled that the verdict in Alabama county court and the Supreme Court of Alabama violated the First Amendment. The decision is considered to be landmark. After financial losses, The New York Times ended its international edition, acquiring a stake in the Paris Herald Tribune, forming the International Herald Tribune. The Times initially published the Pentagon Papers, facing opposition from then-president Richard Nixon. The Supreme Court ruled in The New York Times's favor in New York Times Co. v. United States (1971), allowing the Times and The Washington Post to publish the papers. The New York Times remained cautious in its initial coverage of the Watergate scandal. As Congress began investigating the scandal, the Times furthered its coverage, publishing details on the Huston Plan, alleged wiretapping of reporters and officials, and testimony from James W. McCord Jr. that the Committee for the Re-Election of the President paid the conspirators off. The exodus of readers to suburban New York newspapers, such as Newsday and Gannett papers, adversely affected The New York Times's circulation. Contemporary newspapers balked at additional sections; Time devoted a cover for its criticism and New York wrote that the Times was engaging in "middle-class self-absorption". The New York Times, the Daily News, and the New York Post were the subject of a strike in 1978, allowing emerging newspapers to leverage halted coverage. The Times deliberately avoided coverage of the AIDS epidemic, running its first front-page article in May 1983. Max Frankel's editorial coverage of the epidemic, with mentions of anal intercourse, contrasted with then-executive editor A. M. Rosenthal's puritan approach, intentionally avoiding descriptions of the luridity of gay venues. Following years of waning interest in The New York Times, Sulzberger resigned in January 1992, appointing his son, Arthur Ochs Sulzberger Jr., as publisher. The Internet represented a generational shift within the Times; Sulzberger, who negotiated The New York Times Company's acquisition of The Boston Globe in 1993, derided the Internet, while his son expressed antithetical views. @times appeared on America Online's website in May 1994 as an extension of The New York Times, featuring news articles, film reviews, sports news, and business articles. Despite opposition, several employees of the Times had begun to access the Internet. The online success of publications that traditionally co-existed with the Times—such as America Online, Yahoo, and CNN—and the expansion of websites such as Monster.com and Craigslist that threatened The New York Times's classified advertisement model increased efforts to develop a website. nytimes.com debuted on January 19 and was formally announced three days later. The Times published domestic terrorist Ted Kaczynski's essay Industrial Society and Its Future in 1995, contributing to his arrest after his brother David recognized the essay's penmanship. Following the establishment of nytimes.com, The New York Times retained its journalistic hesitancy under executive editor Joseph Lelyveld, refusing to publish an article reporting on the Clinton–Lewinsky scandal from Drudge Report. nytimes.com editors conflicted with print editors on several occasions, including wrongfully naming security guard Richard Jewell as the suspect in the Centennial Olympic Park bombing and covering the death of Diana, Princess of Wales in greater detail than the print edition. The New York Times Electronic Media Company was adversely affected by the dot-com crash. The Times extensively covered the September 11 attacks. The following day's print issue contained sixty-six articles, the work of over three hundred dispatched reporters. Journalist Judith Miller was the recipient of a package containing a white powder during the 2001 anthrax attacks, furthering anxiety within The New York Times. In September 2002, Miller and military correspondent Michael R. Gordon wrote an article for the Times claiming that Iraq had purchased aluminum tubes. The article was cited by then-president George W. Bush to claim that Iraq was constructing weapons of mass destruction; the theoretical use of aluminum tubes to produce nuclear material was speculation. In March 2003, the United States invaded Iraq, beginning the Iraq War. The New York Times attracted controversy after thirty-six articles from journalist Jayson Blair were discovered to be plagiarized. Criticism over then-executive editor Howell Raines and then-managing editor Gerald M. Boyd mounted following the scandal, culminating in a town hall in which a deputy editor criticized Raines for failing to question Blair's sources in article he wrote on the D.C. sniper attacks. In June 2003, Raines and Boyd resigned. Arthur Ochs Sulzberger Jr. appointed Bill Keller as executive editor. Miller continued to report on the Iraq War as a journalistic embed covering the country's weapons of mass destruction program. Keller and then-Washington bureau chief Jill Abramson unsuccessfully attempted to subside criticism. Conservative media criticized the Times over its coverage of missing explosives from the Al Qa'qaa weapons facility. An article in December 2005 disclosing warrantless surveillance by the National Security Agency contributed to further criticism from the George W. Bush administration and the Senate's refusal to renew the Patriot Act. In the Plame affair, a Central Intelligence Agency inquiry found that Miller had become aware of Valerie Plame's identity through then-vice president Dick Cheney's chief of staff Scooter Libby, resulting in Miller's resignation. During the Great Recession, The New York Times suffered significant fiscal difficulties as a consequence of the subprime mortgage crisis and a decline in classified advertising. Exacerbated by Rupert Murdoch's revitalization of The Wall Street Journal through his acquisition of Dow Jones & Company, The New York Times Company began enacting measures to reduce the newsroom budget. The company was forced to borrow $250 million (equivalent to $373.84 million in 2025) from Mexican billionaire Carlos Slim and fired over one hundred employees by 2010. nytimes.com's coverage of the Eliot Spitzer prostitution scandal, resulting in the resignation of then-New York governor Eliot Spitzer, furthered the legitimacy of the website as a journalistic medium. The Times's economic downturn renewed discussions of an online paywall; The New York Times implemented a paywall in March 2011. Abramson succeeded Keller, continuing her characteristic investigations into corporate and government malfeasance into the Times's coverage. Following conflicts with newly appointed chief executive Mark Thompson's ambitions, Abramson was dismissed by Sulzberger Jr., who named Dean Baquet as her replacement. Leading up to the 2016 presidential election, The New York Times elevated the Hillary Clinton email controversy into a national issue. Donald Trump's upset victory contributed to an increase in subscriptions to the Times. The New York Times experienced unprecedented indignation from Trump, who referred to publications such as the Times as "enemies of the people" at the Conservative Political Action Conference and tweeted his disdain for the newspaper and CNN. In October 2017, The New York Times published an article by journalists Jodi Kantor and Megan Twohey alleging that dozens of women had accused film producer and The Weinstein Company co-chairman Harvey Weinstein of sexual misconduct. The investigation resulted in Weinstein's resignation and conviction, precipitated the Weinstein effect, and served as a catalyst for the #MeToo movement. The New York Times Company vacated the public editor position and eliminated the copy desk in November. Sulzberger Jr. announced his resignation in December 2017, appointing his son, A. G. Sulzberger, as publisher. Trump's relationship—equally diplomatic and negative—marked Sulzberger's tenure. In September 2018, The New York Times published "I Am Part of the Resistance Inside the Trump Administration", an anonymous essay by a self-described Trump administration official later revealed to be Department of Homeland Security chief of staff Miles Taylor. The animosity—which extended to nearly three hundred instances of Trump disparaging the Times by May 2019—culminated in Trump ordering federal agencies to cancel their subscriptions to The New York Times and The Washington Post in October 2019. Trump's tax returns have been the subject of three separate investigations.[c] During the COVID-19 pandemic, the Times began implementing data services and graphs. On May 23, 2020, The New York Times's front page solely featured U.S. Deaths Near 100,000, An Incalculable Loss, a subset of the 100,000 people in the United States who died of COVID-19, the first time that the Times's front page lacked images since they were introduced. Since 2020, The New York Times has focused on broader diversification, developing online games and producing television series. The New York Times Company acquired The Athletic in January 2022. Organization Since 1896, The New York Times has been published by the Ochs-Sulzberger family, having previously been published by Henry Jarvis Raymond until 1869 and by George Jones until 1896. Adolph Ochs published the Times until his death in 1935, when he was succeeded by his son-in-law, Arthur Hays Sulzberger. Sulzberger was publisher until 1961 and was succeeded by Orvil Dryfoos, his son-in-law, who served in the position until his death in 1963. Arthur Ochs Sulzberger succeeded Dryfoos until his resignation in 1992. His son, Arthur Ochs Sulzberger Jr., served as publisher until 2018. The New York Times's current publisher is A. G. Sulzberger, Sulzberger Jr.'s son. As of 2023, the Times's executive editor is Joseph Kahn and the paper's managing editors are Marc Lacey and Carolyn Ryan, having been appointed in June 2022. The New York Times's deputy managing editors are Sam Dolnick, Monica Drake, and Steve Duenes, and the paper's assistant managing editors are Matthew Ericson, Jonathan Galinsky, Hannah Poferl, Sam Sifton, Karron Skog, and Michael Slackman. The New York Times is owned by The New York Times Company, a publicly traded company. The New York Times Company, in addition to the Times, owns Wirecutter, The Athletic, The New York Times Cooking, and The New York Times Games, and acquired Serial Productions and Audm. The New York Times Company holds undisclosed minority investments in multiple other businesses, and formerly owned The Boston Globe and several radio and television stations. The New York Times Company is majority-owned by the Ochs-Sulzberger family through elevated shares in the company's dual-class stock structure held largely in a trust, in effect since the 1950s; as of 2022, the family holds ninety-five percent of The New York Times Company's Class B shares, allowing it to elect seventy percent of the company's board of directors. Class A shareholders have restrictive voting rights. As of 2023, The New York Times Company's chief executive is Meredith Kopit Levien, the company's former chief operating officer who was appointed in September 2020. As of March 2023, The New York Times Company employs 5,800 individuals, including 1,700 journalists according to deputy managing editor Sam Dolnick. Journalists for The New York Times may not run for public office, provide financial support to political candidates or causes, endorse candidates, or demonstrate public support for causes or movements. Journalists are subject to the guidelines established in "Ethical Journalism" and "Guidelines on Integrity". According to the former, Times journalists must abstain from using sources with a personal relationship to them and must not accept reimbursements or inducements from individuals who may be written about in The New York Times, with exceptions for gifts of nominal value. The latter requires attribution and exact quotations, though exceptions are made for linguistic anomalies. Staff writers are expected to ensure the veracity of all written claims, but may delegate researching obscure facts to the research desk. In March 2021, the Times established a committee to avoid journalistic conflicts of interest with work written for The New York Times, following columnist David Brooks's resignation from the Aspen Institute for his undisclosed work on the initiative Weave. The New York Times editorial board was established in 1896 by Adolph Ochs. With the opinion department, the editorial board is independent of the newsroom. Then-editor-in-chief Charles Ransom Miller served as opinion editor from 1883 until his death in 1922. Rollo Ogden succeeded Miller until his death in 1937. From 1937 to 1938, John Huston Finley served as opinion editor; in a prearranged plan, Charles Merz succeeded Finley. Merz served in the position until his retirement in 1961. John Bertram Oakes served as opinion editor from 1961 to 1976, when then-publisher Arthur Ochs Sulzberger appointed Max Frankel. Frankel served in the position until 1986, when he was appointed as executive editor. Jack Rosenthal was the opinion editor from 1986 to 1993. Howell Raines succeeded Rosenthal until 2001, when he was made executive editor. Gail Collins succeeded Raines until her resignation in 2006. From 2007 to 2016, Andrew Rosenthal was the opinion editor. James Bennet succeeded Rosenthal until his resignation in 2020. As of July 2024[update], the editorial board comprises thirteen opinion writers. The New York Times's opinion editor is Kathleen Kingsbury and the deputy opinion editor is Patrick Healy. The New York Times's editorial board was initially opposed to liberal beliefs, opposing women's suffrage in 1900 and 1914. The editorial board began to espouse progressive beliefs during Oakes's tenure, conflicting with the Ochs-Sulzberger family, of which Oakes was a member as Adolph Ochs's nephew; in 1976, Oakes publicly disagreed with Sulzberger's endorsement of Daniel Patrick Moynihan over Bella Abzug in the 1976 Senate Democratic primaries in a letter sent from Martha's Vineyard. Under Rosenthal, the editorial board took positions supporting assault weapons legislation and the legalization of marijuana, but publicly criticized the Obama administration over its portrayal of terrorism. In presidential elections, The New York Times has endorsed a total of twelve Republican candidates and thirty-two Democratic candidates, and has endorsed the Democrat in every election since 1960.[j] With the exception of Wendell Willkie, Republicans endorsed by the Times have won the presidency. In 2016, the editorial board issued an anti-endorsement against Donald Trump for the first time in its history. In February 2020, the editorial board reduced its presence from several editorials each day to occasional editorials for events deemed particularly significant. Since August 2024, the board no longer endorses candidates in local or congressional races in New York. Since 1940, editorial, media, and technology workers of The New York Times have been represented by the New York Times Guild. The Times Guild, along with the Times Tech Guild, are represented by the NewsGuild-CWA. In 1940, Arthur Hays Sulzberger was called upon by the National Labor Relations Board amid accusations that he had discouraged Guild membership in the Times. Over the next few years, the Guild would ratify several contracts, expanding to editorial and news staff in 1942 and maintenance workers in 1943. The New York Times Guild has walked out several times in its history, including for six and a half hours in 1981 and in 2017, when copy editors and reporters walked out at lunchtime in response to the elimination of the copy desk. On December 7, 2022, the union held a one-day strike, the first interruption to The New York Times since 1978. The New York Times Guild reached an agreement in May 2023 to increase minimum salaries for employees and a retroactive bonus. The Times Tech Guild is the largest technology union with collective bargaining rights in the United States. The guild held a second strike beginning on November 4, 2024, threatening the Times's coverage of the 2024 United States presidential election. Content As of August 2025, The New York Times has 11.8 million subscribers, with 11.3 million online-only subscribers and 580,000 print subscribers. The New York Times Company intends to have 15 million subscribers by 2027. The Times's shift towards subscription-based revenue with the debut of an online paywall in 2011 contributed to subscription revenue exceeding advertising revenue the following year, furthered by the 2016 presidential election and Donald Trump. In 2022, Vox wrote that The New York Times's subscribers skew "older, richer, whiter, and more liberal"; to reflect the general population of the United States, the Times has attempted to alter its audience by acquiring The Athletic, investing in verticals such as The New York Times Games, and beginning a marketing campaign showing diverse subscribers to the Times. The New York Times Company chief executive Meredith Kopit Levien stated that the average age of subscribers has remained constant. In October 2001, The New York Times began publishing DealBook, a financial newsletter edited by Andrew Ross Sorkin. The Times had intended to publish the newsletter in September, but delayed its debut following the September 11 attacks. A website for DealBook was established in March 2006. The New York Times began shifting towards DealBook as part of the newspaper's financial coverage in November 2010 with a renewed website and a presence in the Times's print edition. In 2011, the Times began hosting the DealBook Summit, an annual conference hosted by Sorkin. During the COVID-19 pandemic, The New York Times hosted the DealBook Online Summit in 2020 and 2021. The 2022 DealBook Summit featured—among other speakers—former vice president Mike Pence and Israeli prime minister Benjamin Netanyahu, culminating in an interview with former FTX chief executive Sam Bankman-Fried; FTX had filed for bankruptcy several weeks prior. The 2023 DealBook Summit's speakers included vice president Kamala Harris, Israeli president Isaac Herzog, and businessman Elon Musk. In June 2010, The New York Times licensed the political blog FiveThirtyEight in a three-year agreement. The blog, written by Nate Silver, had garnered attention during the 2008 presidential election for predicting the elections in forty-nine of fifty states. FiveThirtyEight appeared on nytimes.com in August. According to Silver, several offers were made for the blog; Silver wrote that a merger of unequals must allow for editorial sovereignty and resources from the acquirer, comparing himself to Groucho Marx. According to The New Republic, FiveThirtyEight drew as much as a fifth of the traffic to nytimes.com during the 2012 presidential election. In July 2013, FiveThirtyEight was sold to ESPN. In an article following Silver's exit, public editor Margaret Sullivan wrote that he was disruptive to the Times's culture for his perspective on probability-based predictions and scorn for polling—having stated that punditry is "fundamentally useless", comparing him to Billy Beane, who implemented sabermetrics in baseball. According to Sullivan, his work was criticized by several notable political journalists. The New Republic obtained a memo in November 2013 revealing then-Washington bureau chief David Leonhardt's ambitions to establish a data-driven newsletter with presidential historian Michael Beschloss, graphic designer Amanda Cox, economist Justin Wolfers, and The New Republic journalist Nate Cohn. By March, Leonhardt had amassed fifteen employees from within The New York Times; the newsletter's staff included individuals who had created the Times's dialect quiz, fourth down analyzer, and a calculator for determining buying or renting a home. The Upshot debuted in April 2014. Fast Company reviewed an article about Illinois Secure Choice—a state-funded retirement saving system—as "neither a terse news item, nor a formal financial advice column, nor a politically charged response to economic policy", citing its informal and neutral tone. The Upshot developed "the needle" for the 2016 presidential election and 2020 presidential elections, a thermometer dial displaying the probability of a candidate winning. In January 2016, Cox was named editor of The Upshot. Kevin Quealy was named editor in June 2022. The New York Times has said it is perceived as a liberal newspaper. An analysis by Pew Research Center in October 2014 placed the Times readership as ideologically liberal based on a scale of 10 political values questions. According to an internal readership poll conducted by The New York Times in 2019, eighty-four percent of readers identified as liberal. The New York Times has struggled internally with how to balance its coverage, dismissing criticism from the left for "sanewashing" right-wing viewpoints in its coverage of Donald Trump. In covering Israel's war on the Gaza Strip that began in 2023, The New York Times instructed its reporters to restrict use of the terms 'Palestine', 'genocide', and 'refugee camps' to specific usages, with data analysis showing a pattern of articles emphasizing Israeli civilians killed by Palestinians over a much larger number of Palestinian civilians killed by Israelis. The group Writers Against the War on Gaza wrote in the blog Mondoweiss that this has contrasted with The New York Times coverage of Russia's invasion of Ukraine, in which Russia is considered a threat to U.S. foreign policy interests, while Israel is considered an ally. In February 1942, The New York Times crossword debuted in The New York Times Magazine; according to Richard Shepard, the attack on Pearl Harbor in December 1941 convinced then-publisher Arthur Hays Sulzberger of the necessity of a crossword. The New York Times has published recipes since the 1850s and has had a separate food section since the 1940s. In 1961, restaurant critic Craig Claiborne published The New York Times Cookbook, an unauthorized cookbook that drew from the Times's recipes. Since 2010, former food editor Amanda Hesser has published The Essential New York Times Cookbook, a compendium of recipes from The New York Times. The Innovation Report in 2014 revealed that the Times had attempted to establish a cooking website since 1998, but faced difficulties with the absence of a defined data structure. In September 2014, The New York Times introduced NYT Cooking, an application and website. Edited by food editor Sam Sifton, the Times's cooking website features 21,000 recipes as of 2022. NYT Cooking features videos as part of an effort by Sifton to hire two former Tasty employees from BuzzFeed. In August 2023, NYT Cooking added personalized recommendations through the cosine similarity of text embeddings of recipe titles. The website also features no-recipe recipes, a concept proposed by Sifton. In May 2016, The New York Times Company announced a partnership with startup Chef'd to form a meal delivery service that would deliver ingredients from The New York Times Cooking recipes to subscribers; Chef'd shut down in July 2018 after failing to accrue capital and secure financing. The Hollywood Reporter reported in September 2022 that the Times would expand its delivery options to US$95 cooking kits curated by chefs such as Nina Compton, Chintan Pandya, and Naoko Takei Moore. That month, the staff of NYT Cooking went on tour with Compton, Pandya, and Moore in Los Angeles, New Orleans, and New York City, culminating in a food festival. In addition, The New York Times offered its own wine club originally operated by the Global Wine Company. The New York Times Wine Club was established in August 2009, during a dramatic decrease in advertising revenue. By 2021, the wine club was managed by Lot18, a company that provides proprietary labels. Lot18 managed the Williams Sonoma Wine Club and its own wine club Tasting Room. The New York Times archives its articles in a basement annex beneath its building known as "the morgue", a venture started by managing editor Carr Van Anda in 1907. The morgue comprises news clippings, a pictures library, and the Times's book and periodicals library. As of 2014, it is the largest library of any media company, dating back to 1851. In November 2018, The New York Times partnered with Google to digitize the Archival Library. Additionally, The New York Times has maintained a virtual microfilm reader known as TimesMachine since 2014. The service launched with archives from 1851 to 1980; in 2016, TimesMachine expanded to include archives from 1981 to 2002. The Times built a pipeline to take in TIFF images, article metadata in XML and an INI file of Cartesian geometry describing the boundaries of the page, and convert it into a PNG of image tiles and JSON containing the information in the XML and INI files. The image tiles are generated using GDAL and displayed using Leaflet, using data from a content delivery network. The Times ran optical character recognition on the articles using Tesseract and shingled and fuzzy string matched the result. The New York Times uses a proprietary content management system known as Scoop for its online content and the Microsoft Word-based content management system CCI for its print content. Scoop was developed in 2008 to serve as a secondary content management system for editors working in CCI to publish their content on the Times's website; as part of The New York Times's online endeavors, editors now write their content in Scoop and send their work to CCI for print publication. Since its introduction, Scoop has superseded several processes within the Times, including print edition planning and collaboration, and features tools such as multimedia integration, notifications, content tagging, and drafts. The New York Times uses private articles for high-profile opinion pieces, such as those written by Russian president Vladimir Putin and actress Angelina Jolie, and for high-level investigations. In January 2012, the Times released Integrated Content Editor (ICE), a revision tracking tool for WordPress and TinyMCE. ICE is integrated within the Times's workflow by providing a unified text editor for print and online editors, reducing the divide between print and online operations. By 2017, The New York Times began developing a new authoring tool to its content management system known as Oak, in an attempt to further the Times's visual efforts in articles and reduce the discrepancy between the mediums in print and online articles. The system reduces the input of editors and supports additional visual mediums in an editor that resembles the appearance of the article. Oak is based on ProseMirror, a JavaScript rich-text editor toolkit, and retains the revision tracking and commenting functionalities of The New York Times's previous systems. Additionally, Oak supports predefined article headers. In 2019, Oak was updated to support collaborative editing using Firebase to update editors's cursor status. Several Google Cloud Functions and Google Cloud Tasks allow articles to be previewed as they will be printed, and the Times's primary MySQL database is regularly updated to update editors on the article status. Style and design Since 1895, The New York Times has maintained a manual of style in several forms. The New York Times Manual of Style and Usage was published on the Times's intranet in 1999. The New York Times uses honorifics when referring to individuals. With the AP Stylebook's removal of honorifics in 2000 and The Wall Street Journal's omission of courtesy titles in May 2023, the Times is the only national newspaper that continues to use honorifics. According to former copy editor Merrill Perlman, The New York Times continues to use honorifics as a "sign of civility". The Times's use of courtesy titles led to an apocryphal rumor that the paper had referred to singer Meat Loaf as "Mr. Loaf". Several exceptions have been made; the former sports section and The New York Times Book Review do not use honorifics. A leaked memo following the killing of Osama bin Laden in May 2011 revealed that editors were given a last-minute instruction to omit the honorific from Osama bin Laden's name, consistent with deceased figures of historic significance, such as Adolf Hitler, Napoleon, and Vladimir Lenin. The New York Times uses academic and military titles for individuals prominently serving in that position. In 1986, the Times began to use Ms., and introduced the gender-neutral title Mx. in 2015. The New York Times uses initials when a subject has expressed a preference, such as Donald Trump. The New York Times maintains a strict but not absolute obscenity policy, including phrases. In a review of the Canadian hardcore punk band Fucked Up, music critic Kelefa Sanneh wrote that the band's name—entirely rendered in asterisks—would not be printed in the Times "unless an American president, or someone similar, says it by mistake"; The New York Times did not repeat then-vice president Dick Cheney's use of "fuck" against then-senator Patrick Leahy in 2004 or then-vice president Joe Biden's remarks that the passage of the Affordable Care Act in 2010 was a "big fucking deal". The Times's profanity policy has been tested by former president Donald Trump. The New York Times published Trump's Access Hollywood tape in October 2016, containing the words "fuck", "pussy", "bitch", and "tits", the first time the publication had published an expletive on its front page, and repeated an explicit phrase for fellatio stated by then-White House communications director Anthony Scaramucci in July 2017. The New York Times omitted Trump's use of the phrase "shithole countries" from its headline in favor of "vulgar language" in January 2018. The Times banned certain words, such as "bitch", "whore", and "sluts", from Wordle in 2022. Journalists for The New York Times do not write their own headlines, but rather copy editors who specifically write headlines. The Times's guidelines insist headline editors get to the main point of an article but avoid giving away endings, if present. Other guidelines include using slang "sparingly", avoiding tabloid headlines, not ending a line on a preposition, article, or adjective, and chiefly, not to pun. The New York Times Manual of Style and Usage states that wordplay, such as "Rubber Industry Bounces Back", is to be tested on a colleague as a canary is to be tested in a coal mine; "when no song bursts forth, start rewriting". The New York Times has amended headlines due to controversy. In 2019, following two back-to-back mass shootings in El Paso and Dayton, the Times used the headline, "Trump Urges Unity vs. Racism", to describe then-president Donald Trump's words after the shootings. After criticism from FiveThirtyEight founder Nate Silver, the headline was changed to, "Assailing Hate But Not Guns". Online, The New York Times's headlines do not face the same length restrictions as headlines that appear in print; print headlines must fit within a column, often six words. Additionally, headlines must "break" properly, containing a complete thought on each line without splitting up prepositions and adverbs. Writers may edit a headline to fit an article more aptly if further developments occur. The Times uses A/B testing for articles on the front page, placing two headlines against each other. At the end of the test, the headlines that receives more traffic is chosen. The alteration of a headline regarding intercepted Russian data used in the Mueller special counsel investigation was noted by Trump in a March 2017 interview with Time, in which he claimed that the headline used the word "wiretapped" in the print version of the paper on January 20, while the digital article on January 19 omitted the word. The headline was intentionally changed in the print version to use "wiretapped" in order to fit within the print guidelines. The nameplate of The New York Times has been unaltered since 1967. In creating the initial nameplate, Henry Jarvis Raymond took as his model the British newspaper The Times, which used a Blackletter style called Textura, popularized following the fall of the Western Roman Empire and regional variations of Alcuin's script, as well as a period. With the change to The New-York Times on September 14, 1857, the nameplate followed. Under George Jones, the terminals of the "N", "r", and "s" were intentionally exaggerated into swashes. The nameplate in the January 15, 1894, issue trimmed the terminals once more, smoothed the edges, and turned the stem supporting the "T" into an ornament. The hyphen was dropped on December 1, 1896, after Adolph Ochs purchased the paper. The descender of the "h" was shortened on December 30, 1914. The largest change to the nameplate was introduced on February 21, 1967, when type designer Ed Benguiat redesigned the logo, most prominently turning the arrow ornament into a diamond. Notoriously, the new logo dropped the period that had followed the word Times up until that point; one reader compared the omission of the period to "performing plastic surgery on Helen of Troy." Picture editor John Radosta worked with a New York University professor to determine that dropping the period saved the paper US$41.28 (equivalent to $398.59 in 2025). Print edition As of December 2023, The New York Times has printed sixty thousand issues, a statistic represented in the paper's masthead to the right of the volume number, the Times's years in publication written in Roman numerals. The volume and issues are separated by four dots representing the edition number of that issue; on the day of the 2000 presidential election, the Times was revised four separate times, necessitating the use of an em dash in place of an ellipsis. The em dash issue was printed hundreds times over before being replaced by the one-dot issue. Despite efforts by newsroom employees to recycle copies sent to The New York Times's office, several copies were kept, including one put on display at the Museum at The Times. From February 7, 1898, to December 31, 1999, the Times's issue number was incorrect by five hundred issues, an error suspected by The Atlantic to be the result of a careless front page type editor. The misreporting was noticed by news editor Aaron Donovan, who was calculating the number of issues in a spreadsheet and noticed the discrepancy. The New York Times celebrated fifty thousand issues on March 14, 1995, an observance that should have occurred on July 26, 1996. The New York Times has reduced the physical size of its print edition while retaining its broadsheet format. The New-York Daily Times debuted at 18 inches (460 mm) across. By the 1950s, the Times was being printed at 16 inches (410 mm) across. In 1953, an increase in paper costs to US$10 (equivalent to $120.34 in 2025) a ton increased newsprint costs to US$21.7 million (equivalent to $326,110,074.63 in 2025) On December 28, 1953, the pages were reduced to 15.5 inches (390 mm). On February 14, 1955, a further reduction to 15 inches (380 mm) occurred, followed by 14.5 and 13.5 inches (370 and 340 mm). On August 6, 2007, the largest cut occurred when the pages were reduced to 12 inches (300 mm),[k] a decision that other broadsheets had previously considered. Then-executive editor Bill Keller stated that a narrower paper would be more beneficial to the reader but acknowledged a net loss in article space of five percent. In 1985, The New York Times Company established a minority stake in a US$21.7 million (equivalent to $326,110,074.63 in 2025) newsprint plant in Clermont, Quebec through Donahue Malbaie. The company sold its equity interest in Donahue Malbaie in 2017. The New York Times often uses large, bolded headlines for major events. For the print version of the Times, these headlines are written by one copy editor, reviewed by two other copy editors, approved by the masthead editors, and polished by other print editors. The process is completed before 8 p.m., but it may be repeated if further development occur, as did take place during the 2020 presidential election. On the day Joe Biden was declared the winner, The New York Times utilized a "hammer headline" reading, "Biden Beats Trump", in all caps and bolded. A dozen journalists discussed several potential headlines, such as "It's Biden" or "Biden's Moment", and prepared for a Donald Trump victory, in which they would use "Trump Prevails". During Trump's first impeachment, the Times drafted the hammer headline, "Trump Impeached". The New York Times altered the ligatures between the E and the A, as not doing so would leave a noticeable gap due to the stem of the A sloping away from the E. The Times reused the tight kerning for "Biden Beats Trump" and Trump's second impeachment, which simply read, "Impeached". In cases where two major events occur on the same day or immediately after each other, The New York Times has used a "paddle wheel" headline, where both headlines are used but split by a line. The term dates back to August 8, 1959, when it was revealed that the United States was monitoring Soviet missile firings and when Explorer 6—shaped like a paddle wheel—launched. Since then, the paddle wheel has been used several times, including on January 21, 1981, when Ronald Reagan was sworn in minutes before Iran released fifty-two American hostages, ending the Iran hostage crisis. At the time, most newspapers favored the end of the hostage crisis, but the Times placed the inauguration above the crisis. Other occasions in which the paddle wheel has been used include on July 26, 2000, when the 2000 Camp David Summit ended without an agreement and when Bush announced that Dick Cheney would be his running mate, and on June 24, 2016, when the United Kingdom European Union membership referendum passed, beginning Brexit, and when the Supreme Court deadlocked in United States v. Texas. The New York Times has run editorials from its editorial board on the front page twice. On June 13, 1920, the Times ran an editorial opposing Warren G. Harding, who was nominated during that year's Republican Party presidential primaries. Amid growing acceptance to run editorials on the front pages from publications such as the Detroit Free Press, The Patriot-News, The Arizona Republic, and The Indianapolis Star, The New York Times ran an editorial on its front page on December 5, 2015, following a terrorist attack in San Bernardino, California, in which fourteen people were killed. The editorial advocates for the prohibition of "slightly modified combat rifles" used in the San Bernardino shooting and "certain kinds of ammunition". Conservative figures, including Texas senator Ted Cruz, The Weekly Standard editor Bill Kristol, Fox & Friends co-anchor Steve Doocy, and then-New Jersey governor Chris Christie criticized the Times. Talk radio host Erick Erickson acquired an issue of The New York Times to fire several rounds into the paper, posting a picture online. Since 1997, The New York Times's primary distribution center is located in College Point, Queens. The facility is 300,000 ft2 (28,000 m2) and employs 170 people as of 2017. The College Point distribution center prints 300,000 to 800,000 newspapers daily. On most occasions, presses start before 11 p.m. and finish before 3 a.m. A robotic crane grabs a roll of newsprint and several rollers ensure ink can be printed on paper. The final newspapers are wrapped in plastic and shipped out. As of 2018, the College Point facility accounted for 41 percent of production. Other copies are printed at 26 other publications, such as The Atlanta Journal-Constitution, The Dallas Morning News, The Santa Fe New Mexican, and the Courier Journal. With the decline of newspapers, particularly regional publications, the Times must travel further; for example, newspapers for Hawaii are flown from San Francisco on United Airlines, and Sunday papers are flown from Los Angeles on Hawaiian Airlines. Computer glitches, mechanical issues, and weather phenomena affect circulation but do not stop the paper from reaching customers. The College Point facility prints over two dozen other papers, including The Wall Street Journal and USA Today. The New York Times has halted its printing process several times to account for major developments. The first printing stoppage occurred on March 31, 1968, when then-president Lyndon B. Johnson announced that he would not seek a second term. Other press stoppages include May 19, 1994, for the death of former first lady Jacqueline Kennedy Onassis, and July 17, 1996, for Trans World Airlines Flight 800. The 2000 presidential election necessitated two press stoppages. Al Gore appeared to concede on November 8, forcing then-executive editor Joseph Lelyveld to stop the Times's presses to print a new headline, "Bush Appears to Defeat Gore", with a story that stated George W. Bush was elected president. However, Gore held off his concession speech over doubts over Florida. Lelyveld reran the headline, "Bush and Gore Vie for an Edge". Since 2000, three printing stoppages have been issued for the death of William Rehnquist on September 3, 2005, for the killing of Osama bin Laden on May 1, 2011, and for the passage of the Marriage Equality Act in the New York State Assembly and subsequent signage by then-governor Andrew Cuomo on June 24, 2011. Online platforms The New York Times website is hosted at nytimes.com. It has undergone several major redesigns and infrastructure developments since its debut. In April 2006, The New York Times redesigned its website with an emphasis on multimedia. In preparation for Super Tuesday in February 2008, the Times developed a live election system using the Associated Press's File Transfer Protocol (FTP) service and a Ruby on Rails application; nytimes.com experienced its largest traffic on Super Tuesday and the day after. The NYTimes application debuted with the introduction of the App Store on July 10, 2008. Engadget's Scott McNulty wrote critically of the app, negatively comparing it to The New York Times's mobile website. An iPad version with select articles was released on April 3, 2010, with the release of the first-generation iPad. In October, The New York Times expanded NYT Editors' Choice to include the paper's full articles. NYT for iPad was free until 2011. The Times applications on iPhone and iPad began offering in-app subscriptions in July 2011. The Times released a web application for iPad—featuring a format summarizing trending headlines on Twitter—and a Windows 8 application in October 2012. Efforts to ensure profitability through an online magazine and a "Need to Know" subscription emerged in Adweek in July 2013. In March 2014, The New York Times announced three applications—NYT Now, an application that offers pertinent news in a blog format, and two unnamed applications, later known as NYT Opinion and NYT Cooking—to diversify its product laterals. The Daily is the modern front page of The New York Times. The New York Times manages several podcasts, including multiple podcasts with Serial Productions. The Times's longest-running podcast is The Book Review Podcast, debuting as Inside The New York Times Book Review in April 2006. The New York Times's defining podcast is The Daily, a daily news podcast hosted by Michael Barbaro which debuted on February 1, 2017. Between March 2022 and March 2025, the approximately 30 minute programme was co-hosted with Sabrina Tavernise. Beginning in April 2025 Barbaro was joined by two new regular co-hosts, Natalie Kitroeff and Rachel Abrams. The Interview was launched in 2024 and is hosted weekly by David Marchese and Lulu Garcia-Navarro. Episodes typically last 40 to 50 minutes. Condensed versions of the interviews are published simultaneously in The New York Times Magazine. Guests have included politicians, actors, influential experts, media figures and high-profile writers. In October 2021, The New York Times began testing "New York Times Audio", an application featuring podcasts from the Times, audio versions of articles—including from other publications through Audm, and archives from This American Life. The application debuted in May 2023 exclusively on iOS for Times subscribers. New York Times Audio includes exclusive podcasts such as The Headlines, a daily news recap, and Shorts, short audio stories under ten minutes. In addition, a "Reporter Reads" section features Times journalists reading their articles and providing commentary. The New York Times has used video games as part of its journalistic efforts, among the first publications to do so, contributing to an increase in Internet traffic; the publication has also developed its own video games. In 2014, The New York Times Magazine introduced Spelling Bee, a word game in which players guess words from a set of letters in a honeycomb and are awarded points for the length of the word and receive extra points if the word is a pangram. The game was proposed by Will Shortz, created by Frank Longo, and has been maintained by Sam Ezersky. In May 2018, Spelling Bee was published on nytimes.com, furthering its popularity. In February 2019, the Times introduced Letter Boxed, in which players form words from letters placed on the edges of a square box, followed in June 2019 by Tiles, a matching game in which players form sequences of tile pairings, and Vertex, in which players connect vertices to assemble an image. In July 2023, The New York Times introduced Connections, in which players identify groups of words that are connected by a common property. In April, the Times introduced Digits, a game that required using operations on different values to reach a set number; Digits was shut down in August. In March 2024, The New York Times released Strands, a themed word search. In January 2022, The New York Times Company acquired Wordle, a word game developed by Josh Wardle in 2021, at a valuation in the "low-seven figures". The acquisition was proposed by David Perpich, a member of the Sulzberger family who proposed the purchase to Knight over Slack after reading about the game. The Washington Post purportedly considered acquiring Wordle, according to Vanity Fair. At the 2022 Game Developers Conference, Wardle stated that he was overwhelmed by the volume of Wordle facsimiles and overzealous monetization practices in other games. Concerns over The New York Times monetizing Wordle by implementing a paywall mounted; Wordle is a client-side browser game and can be played offline by downloading its webpage. Wordle moved to the Times's servers and website in February. The game was added to the NYT Games application in August, necessitating it be rewritten in the JavaScript library React. In November, The New York Times announced that Tracy Bennett would be the Wordle's editor. Other publications The New York Times Magazine and The Boston Globe Magazine are the only weekly Sunday magazines following The Washington Post Magazine's cancellation in December 2022. In February 2016, The New York Times introduced a Spanish website, The New York Times en Español. The website, intended to be read on mobile devices, would contain translated articles from the Times and reporting from journalists based in Mexico City. The Times en Español's style editor is Paulina Chavira, who has advocated for pluralistic Spanish to accommodate the variety of nationalities in the newsroom's journalists and wrote a stylebook for The New York Times en Español. Articles the Times intends to publish in Spanish are sent to a translation agency and adapted for Spanish writing conventions; the present progressive tense may be used for forthcoming events in English, but other tenses are preferable in Spanish. The Times en Español consults the Real Academia Española and Fundéu and frequently modifies the use of diacritics—such as using an acute accent for the Cártel de Sinaloa but not the Cartel de Medellín—and using the gender-neutral pronoun elle. Headlines in The New York Times en Español are not capitalized. The Times en Español publishes El Times, a newsletter led by Elda Cantú intended for all Spanish speakers. In September 2019, The New York Times ended The New York Times en Español's separate operations. A study published in The Translator in 2023 found that the Times en Español engaged in tabloidization. In June 2012, The New York Times introduced a Chinese website, 纽约时报中文, in response to Chinese editions created by The Wall Street Journal and the Financial Times. Conscious to censorship, the Times established servers outside of China and affirmed that the website would uphold the paper's journalistic standards; the government of China had previously blocked articles from nytimes.com through the Great Firewall, and the website was blocked in China until August 2001 after then-general secretary Jiang Zemin met with journalists from The New York Times. Then-foreign editor Joseph Kahn assisted in the establishment of cn.nytimes.com, an effort that contributed to his appointment as executive editor in April 2022. In October 2012, 纽约时报中文 published an article detailing the wealth of then-premier Wen Jiabao's family. In response, the government of China blocked access to nytimes.com and cn.nytimes.com and references to the Times and Wen were censored on microblogging service Sina Weibo. In March 2015, a mirror of 纽约时报中文 and the website for GreatFire were the targets for a government-sanctioned distributed denial of service attack on GitHub in March 2015, disabling access to the service for several days. Chinese authorities requested the removal of The New York Times's news applications from the App Store in December 2016. Awards and recognition As of 2023, The New York Times has received 137 Pulitzer Prizes, the most of any publication. The New York Times is considered a newspaper of record in the United States.[l] The Times is the largest metropolitan newspaper in the United States; as of 2022, The New York Times is the second-largest newspaper by print circulation in the United States behind The Wall Street Journal. A study published in Science, Technology, & Human Values in 2013 found that The New York Times received more citations in academic journals than the American Sociological Review, Research Policy, or the Harvard Law Review. With sixteen million unique records, the Times is the third-most referenced source in Common Crawl, a collection of online material used in datasets such as GPT-3, behind Wikipedia and a United States patent database. The New Yorker's Max Norman wrote in March 2023 that the Times has shaped mainstream English usage. In a January 2018 article for The Washington Post, Margaret Sullivan stated that The New York Times affects the "whole media and political ecosystem". The New York Times's nascent success has led to concerns over media consolidation, particularly amid the decline of newspapers. In 2006, economists Lisa George and Joel Waldfogel examined the consequences of the Times's national distribution strategy and audience with circulation of local newspapers, finding that local circulation decreased among college-educated readers. The effect of The New York Times in this manner was observed in The Forum of Fargo-Moorhead, the newspaper of record for Fargo, North Dakota. Axios founder Jim VandeHei opined that the Times is "going to basically be a monopoly" in an opinion piece written by then-media columnist and former BuzzFeed News editor-in-chief Ben Smith; in the article, Smith cites the strength of The New York Times's journalistic workforce, broadening content, and the expropriation of Gawker editor-in-chief Choire Sicha, Recode editor-in-chief Kara Swisher, and Quartz editor-in-chief Kevin Delaney. Smith compared the Times to the New York Yankees during their 1927 season containing Murderers' Row. Controversies Since 2003, studies analyzing coverage of the Israeli–Palestinian conflict in the New York Times have demonstrated a bias against Palestinians and in favor of Israel.[m] The New York Times has received criticism for its coverage of the Gaza war and genocide. In April 2024, The Intercept reported that a November 2023 internal memorandum by Susan Wessling and Philip Pan instructed journalists to reduce using the terms "genocide" and "ethnic cleansing" and to avoid using the phrase "occupied territory" in the context of Palestinian land, "Palestine" except in rare circumstances, and the term "refugee camps" to describe areas of Gaza despite recognition from the United Nations. A spokesperson from the Times stated that issuing guidance was standard practice. An analysis by The Intercept noted that The New York Times described Israeli deaths as a massacre nearly sixty times, but had only described Palestinian deaths as a massacre once. Writers and editors have left the newspaper due to its coverage of events in Gaza, including Jazmine Hughes and Jamie Lauren Keiles. In December 2023, The New York Times published an investigation titled "'Screams Without Words': How Hamas Weaponized Sexual Violence on Oct. 7", alleging that Hamas weaponized sexual and gender-based violence during its armed incursion on Israel. The investigation was the subject of an article from The Intercept questioning the journalistic acumen of Anat Schwartz, a filmmaker involved in the inquiry who had no prior reporting experience and agreed with a post stating Israel should "violate any norm, on the way to victory", doubting the veracity of the opening claim that Gal Abdush was raped in a timespan disputed by her family, and alleging that the Times was pressured by the Committee for Accuracy in Middle East Reporting in America. The New York Times initiated an inquiry into the leaking of confidential information about the report to other outlets, which received criticism from NewsGuild of New York president Susan DeCarava for purported racial targeting; the Times's investigation was inconclusive, but found gaps in the way proprietary journalistic material is handled. The New York Times Building has been a site of protest action during the Gaza war and genocide, including a November 2023 sit-in demanding that The Times's editorial board publicly call for a ceasefire and accusing the media company of "complicity in laundering genocide", a February 29, 2024, protest and press conference following the release of The Intercept's critical investigation into the NYT "Screams Without Words" exposé, and an action on July 30, 2025, in which protesters spray-painted "NYT Lies, Gaza dies" on the building's glass facade. In addition, protesters blocked The New York Times's distribution center March 14, 2024 and executive editor Joseph Kahn's residence was splattered with red paint on August 25, 2025. The collective Writers Against the War on Gaza, which publishes the mock publication The New York War Crimes, has been associated with protests against The New York Times. On October 27, 2025, 300 writers—including scholars, journalists, and public intellectuals—pledged to boycott The New York Times and withhold contributions to the paper in protest of what they describe as its complicity in the Gaza genocide, demanding 1) a review of anti-Palestinian bias in the newsroom, 2) a retraction of "Screams Without Words", and 3) a call from the editorial board for a US arms embargo on Israel. Among the initial signatories, about 150 had previously contributed to the Times. The New York Times has received criticism regarding its coverage of transgender people. When it published an opinion piece by Weill Cornell Medicine professor Richard A. Friedman called "How Changeable Is Gender?" in August 2015, Vox's German Lopez criticized Friedman as suggesting that parents and doctors might be right in letting children suffer from severe dysphoria in case something changes down the line, and as implying that conversion therapy may work for transgender children. In February 2023, nearly one thousand current and former Times writers and contributors wrote an open letter addressed to standards editor Philip B. Corbett, criticizing the paper's coverage of transgender, non-binary, and gender-nonconforming people; some of the Times's articles have been cited in state legislatures attempting to justify criminalizing gender-affirming care. Contributors wrote in the open letter that "the Times has in recent years treated gender diversity with an eerily familiar mix of pseudoscience and euphemistic, charged language, while publishing reporting on trans children that omits relevant information about its sources."[n] According to former Times journalist Billie Jean Sweeney, a push for writers to challenge “every aspect of being trans”, ranging from gender-inclusive language to access to medical care, came from the top in 2022 after leadership was handed over to A. G. Sulzberger, Joe Kahn, and Carolyn Ryan; as part of an effort to win good will with the Trump campaign without incurring backlash from the general populace. The Times has continually denied any bias in its reporting, insisting that its coverage of “fiercely contested medical and legal debates” is fair and balanced, and that it would not tolerate journalists protesting its transgender coverage.

Contents Elon Musk Elon Reeve Musk (/ˈiːlɒn/ EE-lon; born June 28, 1971) is a businessman and entrepreneur known for his leadership of Tesla, SpaceX, Twitter, and xAI. Musk has been the wealthiest person in the world since 2025; as of February 2026,[update] Forbes estimates his net worth to be around US$852 billion. Born into a wealthy family in Pretoria, South Africa, Musk emigrated in 1989 to Canada; he has Canadian citizenship since his mother was born there. He received bachelor's degrees in 1997 from the University of Pennsylvania before moving to California to pursue business ventures. In 1995, Musk co-founded the software company Zip2. Following its sale in 1999, he co-founded X.com, an online payment company that later merged to form PayPal, which was acquired by eBay in 2002. Musk also became an American citizen in 2002. In 2002, Musk founded the space technology company SpaceX, becoming its CEO and chief engineer; the company has since led innovations in reusable rockets and commercial spaceflight. Musk joined the automaker Tesla as an early investor in 2004 and became its CEO and product architect in 2008; it has since become a leader in electric vehicles. In 2015, he co-founded OpenAI to advance artificial intelligence (AI) research, but later left; growing discontent with the organization's direction and their leadership in the AI boom in the 2020s led him to establish xAI, which became a subsidiary of SpaceX in 2026. In 2022, he acquired the social network Twitter, implementing significant changes, and rebranding it as X in 2023. His other businesses include the neurotechnology company Neuralink, which he co-founded in 2016, and the tunneling company the Boring Company, which he founded in 2017. In November 2025, a Tesla pay package worth $1 trillion for Musk was approved, which he is to receive over 10 years if he meets specific goals. Musk was the largest donor in the 2024 U.S. presidential election, where he supported Donald Trump. After Trump was inaugurated as president in early 2025, Musk served as Senior Advisor to the President and as the de facto head of the Department of Government Efficiency (DOGE). After a public feud with Trump, Musk left the Trump administration and returned to managing his companies. Musk is a supporter of global far-right figures, causes, and political parties. His political activities, views, and statements have made him a polarizing figure. Musk has been criticized for COVID-19 misinformation, promoting conspiracy theories, and affirming antisemitic, racist, and transphobic comments. His acquisition of Twitter was controversial due to a subsequent increase in hate speech and the spread of misinformation on the service, following his pledge to decrease censorship. His role in the second Trump administration attracted public backlash, particularly in response to DOGE. The emails he sent to Jeffrey Epstein are included in the Epstein files, which were published between 2025–26 and became a topic of worldwide debate. Early life Elon Reeve Musk was born on June 28, 1971, in Pretoria, South Africa's administrative capital. He is of British and Pennsylvania Dutch ancestry. His mother, Maye (née Haldeman), is a model and dietitian born in Saskatchewan, Canada, and raised in South Africa. Musk therefore holds both South African and Canadian citizenship from birth. His father, Errol Musk, is a South African electromechanical engineer, pilot, sailor, consultant, emerald dealer, and property developer, who partly owned a rental lodge at Timbavati Private Nature Reserve. His maternal grandfather, Joshua N. Haldeman, who died in a plane crash when Elon was a toddler, was an American-born Canadian chiropractor, aviator and political activist in the technocracy movement who moved to South Africa in 1950. Elon has a younger brother, Kimbal, a younger sister, Tosca, and four paternal half-siblings. Musk was baptized as a child in the Anglican Church of Southern Africa. Despite both Elon and Errol previously stating that Errol was a part owner of a Zambian emerald mine, in 2023, Errol recounted that the deal he made was to receive "a portion of the emeralds produced at three small mines". Errol was elected to the Pretoria City Council as a representative of the anti-apartheid Progressive Party and has said that his children shared their father's dislike of apartheid. After his parents divorced in 1979, Elon, aged around 9, chose to live with his father because Errol Musk had an Encyclopædia Britannica and a computer. Elon later regretted his decision and became estranged from his father. Elon has recounted trips to a wilderness school that he described as a "paramilitary Lord of the Flies" where "bullying was a virtue" and children were encouraged to fight over rations. In one incident, after an altercation with a fellow pupil, Elon was thrown down concrete steps and beaten severely, leading to him being hospitalized for his injuries. Elon described his father berating him after he was discharged from the hospital. Errol denied berating Elon and claimed, "The [other] boy had just lost his father to suicide, and Elon had called him stupid. Elon had a tendency to call people stupid. How could I possibly blame that child?" Elon was an enthusiastic reader of books, and had attributed his success in part to having read The Lord of the Rings, the Foundation series, and The Hitchhiker's Guide to the Galaxy. At age ten, he developed an interest in computing and video games, teaching himself how to program from the VIC-20 user manual. At age twelve, Elon sold his BASIC-based game Blastar to PC and Office Technology magazine for approximately $500 (equivalent to $1,600 in 2025). Musk attended Waterkloof House Preparatory School, Bryanston High School, and then Pretoria Boys High School, where he graduated. Musk was a decent but unexceptional student, earning a 61/100 in Afrikaans and a B on his senior math certification. Musk applied for a Canadian passport through his Canadian-born mother to avoid South Africa's mandatory military service, which would have forced him to participate in the apartheid regime, as well as to ease his path to immigration to the United States. While waiting for his application to be processed, he attended the University of Pretoria for five months. Musk arrived in Canada in June 1989, connected with a second cousin in Saskatchewan, and worked odd jobs, including at a farm and a lumber mill. In 1990, he entered Queen's University in Kingston, Ontario. Two years later, he transferred to the University of Pennsylvania, where he studied until 1995. Although Musk has said that he earned his degrees in 1995, the University of Pennsylvania did not award them until 1997 – a Bachelor of Arts in physics and a Bachelor of Science in economics from the university's Wharton School. He reportedly hosted large, ticketed house parties to help pay for tuition, and wrote a business plan for an electronic book-scanning service similar to Google Books. In 1994, Musk held two internships in Silicon Valley: one at energy storage startup Pinnacle Research Institute, which investigated electrolytic supercapacitors for energy storage, and another at Palo Alto–based startup Rocket Science Games. In 1995, he was accepted to a graduate program in materials science at Stanford University, but did not enroll. Musk decided to join the Internet boom of the 1990s, applying for a job at Netscape, to which he reportedly never received a response. The Washington Post reported that Musk lacked legal authorization to remain and work in the United States after failing to enroll at Stanford. In response, Musk said he was allowed to work at that time and that his student visa transitioned to an H1-B. According to numerous former business associates and shareholders, Musk said he was on a student visa at the time. Business career In 1995, Musk, his brother Kimbal, and Greg Kouri founded the web software company Zip2 with funding from a group of angel investors. They housed the venture at a small rented office in Palo Alto. Replying to Rolling Stone, Musk denounced the notion that they started their company with funds borrowed from Errol Musk, but in a tweet, he recognized that his father contributed 10% of a later funding round. The company developed and marketed an Internet city guide for the newspaper publishing industry, with maps, directions, and yellow pages. According to Musk, "The website was up during the day and I was coding it at night, seven days a week, all the time." To impress investors, Musk built a large plastic structure around a standard computer to create the impression that Zip2 was powered by a small supercomputer. The Musk brothers obtained contracts with The New York Times and the Chicago Tribune, and persuaded the board of directors to abandon plans for a merger with CitySearch. Musk's attempts to become CEO were thwarted by the board. Compaq acquired Zip2 for $307 million in cash in February 1999 (equivalent to $590,000,000 in 2025), and Musk received $22 million (equivalent to $43,000,000 in 2025) for his 7-percent share. In 1999, Musk co-founded X.com, an online financial services and e-mail payment company. The startup was one of the first federally insured online banks, and, in its initial months of operation, over 200,000 customers joined the service. The company's investors regarded Musk as inexperienced and replaced him with Intuit CEO Bill Harris by the end of the year. The following year, X.com merged with online bank Confinity to avoid competition. Founded by Max Levchin and Peter Thiel, Confinity had its own money-transfer service, PayPal, which was more popular than X.com's service. Within the merged company, Musk returned as CEO. Musk's preference for Microsoft software over Unix created a rift in the company and caused Thiel to resign. Due to resulting technological issues and lack of a cohesive business model, the board ousted Musk and replaced him with Thiel in 2000.[b] Under Thiel, the company focused on the PayPal service and was renamed PayPal in 2001. In 2002, PayPal was acquired by eBay for $1.5 billion (equivalent to $2,700,000,000 in 2025) in stock, of which Musk—the largest shareholder with 11.72% of shares—received $175.8 million (equivalent to $320,000,000 in 2025). In 2017, Musk purchased the domain X.com from PayPal for an undisclosed amount, stating that it had sentimental value. In 2001, Musk became involved with the nonprofit Mars Society and discussed funding plans to place a growth-chamber for plants on Mars. Seeking a way to launch the greenhouse payloads into space, Musk made two unsuccessful trips to Moscow to purchase intercontinental ballistic missiles (ICBMs) from Russian companies NPO Lavochkin and Kosmotras. Musk instead decided to start a company to build affordable rockets. With $100 million of his early fortune, (equivalent to $180,000,000 in 2025) Musk founded SpaceX in May 2002 and became the company's CEO and Chief Engineer. SpaceX attempted its first launch of the Falcon 1 rocket in 2006. Although the rocket failed to reach Earth orbit, it was awarded a Commercial Orbital Transportation Services program contract from NASA, then led by Mike Griffin. After two more failed attempts that nearly caused Musk to go bankrupt, SpaceX succeeded in launching the Falcon 1 into orbit in 2008. Later that year, SpaceX received a $1.6 billion NASA contract (equivalent to $2,400,000,000 in 2025) for Falcon 9-launched Dragon spacecraft flights to the International Space Station (ISS), replacing the Space Shuttle after its 2011 retirement. In 2012, the Dragon vehicle docked with the ISS, a first for a commercial spacecraft. Working towards its goal of reusable rockets, in 2015 SpaceX successfully landed the first stage of a Falcon 9 on a land platform. Later landings were achieved on autonomous spaceport drone ships, an ocean-based recovery platform. In 2018, SpaceX launched the Falcon Heavy; the inaugural mission carried Musk's personal Tesla Roadster as a dummy payload. Since 2019, SpaceX has been developing Starship, a reusable, super heavy-lift launch vehicle intended to replace the Falcon 9 and Falcon Heavy. In 2020, SpaceX launched its first crewed flight, the Demo-2, becoming the first private company to place astronauts into orbit and dock a crewed spacecraft with the ISS. In 2024, NASA awarded SpaceX an $843 million (equivalent to $865,000,000 in 2025) contract to build a spacecraft that NASA will use to deorbit the ISS at the end of its lifespan. In 2015, SpaceX began development of the Starlink constellation of low Earth orbit satellites to provide satellite Internet access. After the launch of prototype satellites in 2018, the first large constellation was deployed in May 2019. As of May 2025[update], over 7,600 Starlink satellites are operational, comprising 65% of all operational Earth satellites. The total cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in 2020 to be $10 billion (equivalent to $12,000,000,000 in 2025).[c] During the Russian invasion of Ukraine, Musk provided free Starlink service to Ukraine, permitting Internet access and communication at a yearly cost to SpaceX of $400 million (equivalent to $440,000,000 in 2025). However, Musk refused to block Russian state media on Starlink. In 2023, Musk denied Ukraine's request to activate Starlink over Crimea to aid an attack against the Russian navy, citing fears of a nuclear response. Tesla, Inc., originally Tesla Motors, was incorporated in July 2003 by Martin Eberhard and Marc Tarpenning. Both men played active roles in the company's early development prior to Musk's involvement. Musk led the Series A round of investment in February 2004; he invested $6.35 million (equivalent to $11,000,000 in 2025), became the majority shareholder, and joined Tesla's board of directors as chairman. Musk took an active role within the company and oversaw Roadster product design, but was not deeply involved in day-to-day business operations. Following a series of escalating conflicts in 2007 and the 2008 financial crisis, Eberhard was ousted from the firm.[page needed] Musk assumed leadership of the company as CEO and product architect in 2008. A 2009 lawsuit settlement with Eberhard designated Musk as a Tesla co-founder, along with Tarpenning and two others. Tesla began delivery of the Roadster, an electric sports car, in 2008. With sales of about 2,500 vehicles, it was the first mass production all-electric car to use lithium-ion battery cells. Under Musk, Tesla has since launched several well-selling electric vehicles, including the four-door sedan Model S (2012), the crossover Model X (2015), the mass-market sedan Model 3 (2017), the crossover Model Y (2020), and the pickup truck Cybertruck (2023). In May 2020, Musk resigned as chairman of the board as part of the settlement of a lawsuit from the SEC over him tweeting that funding had been "secured" for potentially taking Tesla private. The company has also constructed multiple lithium-ion battery and electric vehicle factories, called Gigafactories. Since its initial public offering in 2010, Tesla stock has risen significantly; it became the most valuable carmaker in summer 2020, and it entered the S&P 500 later that year. In October 2021, it reached a market capitalization of $1 trillion (equivalent to $1,200,000,000,000 in 2025), the sixth company in U.S. history to do so. Musk provided the initial concept and financial capital for SolarCity, which his cousins Lyndon and Peter Rive founded in 2006. By 2013, SolarCity was the second largest provider of solar power systems in the United States. In 2014, Musk promoted the idea of SolarCity building an advanced production facility in Buffalo, New York, triple the size of the largest solar plant in the United States. Construction of the factory started in 2014 and was completed in 2017. It operated as a joint venture with Panasonic until early 2020. Tesla acquired SolarCity for $2 billion in 2016 (equivalent to $2,700,000,000 in 2025) and merged it with its battery unit to create Tesla Energy. The deal's announcement resulted in a more than 10% drop in Tesla's stock price; at the time, SolarCity was facing liquidity issues. Multiple shareholder groups filed a lawsuit against Musk and Tesla's directors, stating that the purchase of SolarCity was done solely to benefit Musk and came at the expense of Tesla and its shareholders. Tesla directors settled the lawsuit in January 2020, leaving Musk the sole remaining defendant. Two years later, the court ruled in Musk's favor. In 2016, Musk co-founded Neuralink, a neurotechnology startup, with an investment of $100 million. Neuralink aims to integrate the human brain with artificial intelligence (AI) by creating devices that are embedded in the brain. Such technology could enhance memory or allow the devices to communicate with software. The company also hopes to develop devices to treat neurological conditions like spinal cord injuries. In 2022, Neuralink announced that clinical trials would begin by the end of the year. In September 2023, the Food and Drug Administration approved Neuralink to initiate six-year human trials. Neuralink has conducted animal testing on macaques at the University of California, Davis. In 2021, the company released a video in which a macaque played the video game Pong via a Neuralink implant. The company's animal trials—which have caused the deaths of some monkeys—have led to claims of animal cruelty. The Physicians Committee for Responsible Medicine has alleged that Neuralink violated the Animal Welfare Act. Employees have complained that pressure from Musk to accelerate development has led to botched experiments and unnecessary animal deaths. In 2022, a federal probe was launched into possible animal welfare violations by Neuralink.[needs update] In 2017, Musk founded the Boring Company to construct tunnels; he also revealed plans for specialized, underground, high-occupancy vehicles that could travel up to 150 miles per hour (240 km/h) and thus circumvent above-ground traffic in major cities. Early in 2017, the company began discussions with regulatory bodies and initiated construction of a 30-foot (9.1 m) wide, 50-foot (15 m) long, and 15-foot (4.6 m) deep "test trench" on the premises of SpaceX's offices, as that required no permits. The Los Angeles tunnel, less than two miles (3.2 km) in length, debuted to journalists in 2018. It used Tesla Model Xs and was reported to be a rough ride while traveling at suboptimal speeds. Two tunnel projects announced in 2018, in Chicago and West Los Angeles, have been canceled. A tunnel beneath the Las Vegas Convention Center was completed in early 2021. Local officials have approved further expansions of the tunnel system. April 14, 2022 In early 2017, Musk expressed interest in buying Twitter and had questioned the platform's commitment to freedom of speech. By 2022, Musk had reached 9.2% stake in the company, making him the largest shareholder.[d] Musk later agreed to a deal that would appoint him to Twitter's board of directors and prohibit him from acquiring more than 14.9% of the company. Days later, Musk made a $43 billion offer to buy Twitter. By the end of April Musk had successfully concluded his bid for approximately $44 billion. This included approximately $12.5 billion in loans and $21 billion in equity financing. Having backtracked on his initial decision, Musk bought the company on October 27, 2022. Immediately after the acquisition, Musk fired several top Twitter executives including CEO Parag Agrawal; Musk became the CEO instead. Under Elon Musk, Twitter instituted monthly subscriptions for a "blue check", and laid off a significant portion of the company's staff. Musk lessened content moderation and hate speech also increased on the platform after his takeover. In late 2022, Musk released internal documents relating to Twitter's moderation of Hunter Biden's laptop controversy in the lead-up to the 2020 presidential election. Musk also promised to step down as CEO after a Twitter poll, and five months later, Musk stepped down as CEO and transitioned his role to executive chairman and chief technology officer (CTO). Despite Musk stepping down as CEO, X continues to struggle with challenges such as viral misinformation, hate speech, and antisemitism controversies. Musk has been accused of trying to silence some of his critics such as Twitch streamer Asmongold, who criticized him during one of his streams. Musk has been accused of removing their accounts' blue checkmarks, which hinders visibility and is considered a form of shadow banning, or suspending their accounts without justification. Other activities In August 2013, Musk announced plans for a version of a vactrain, and assigned engineers from SpaceX and Tesla to design a transport system between Greater Los Angeles and the San Francisco Bay Area, at an estimated cost of $6 billion. Later that year, Musk unveiled the concept, dubbed the Hyperloop, intended to make travel cheaper than any other mode of transport for such long distances. In December 2015, Musk co-founded OpenAI, a not-for-profit artificial intelligence (AI) research company aiming to develop artificial general intelligence, intended to be safe and beneficial to humanity. Musk pledged $1 billion of funding to the company, and initially gave $50 million. In 2018, Musk left the OpenAI board. Since 2018, OpenAI has made significant advances in machine learning. In July 2023, Musk launched the artificial intelligence company xAI, which aims to develop a generative AI program that competes with existing offerings like OpenAI's ChatGPT. Musk obtained funding from investors in SpaceX and Tesla, and xAI hired engineers from Google and OpenAI. December 16, 2022 Musk uses a private jet owned by Falcon Landing LLC, a SpaceX-linked company, and acquired a second jet in August 2020. His heavy use of the jets and the consequent fossil fuel usage have received criticism. Musk's flight usage is tracked on social media through ElonJet. In December 2022, Musk banned the ElonJet account on Twitter, and made temporary bans on the accounts of journalists that posted stories regarding the incident, including Donie O'Sullivan, Keith Olbermann, and journalists from The New York Times, The Washington Post, CNN, and The Intercept. In October 2025, Musk's company xAI launched Grokipedia, an AI-generated online encyclopedia that he promoted as an alternative to Wikipedia. Articles on Grokipedia are generated and reviewed by xAI's Grok chatbot. Media coverage and academic analysis described Grokipedia as frequently reusing Wikipedia content but framing contested political and social topics in line with Musk's own views and right-wing narratives. A study by Cornell University researchers and NBC News stated that Grokipedia cites sources that are blacklisted or considered "generally unreliable" on Wikipedia, for example, the conspiracy site Infowars and the neo-Nazi forum Stormfront. Wired, The Guardian and Time criticized Grokipedia for factual errors and for presenting Musk himself in unusually positive terms while downplaying controversies. Politics Musk is an outlier among business leaders who typically avoid partisan political advocacy. Musk was a registered independent voter when he lived in California. Historically, he has donated to both Democrats and Republicans, many of whom serve in states in which he has a vested interest. Since 2022, his political contributions have mostly supported Republicans, with his first vote for a Republican going to Mayra Flores in the 2022 Texas's 34th congressional district special election. In 2024, he started supporting international far-right political parties, activists, and causes, and has shared misinformation and numerous conspiracy theories. Since 2024, his views have been generally described as right-wing. Musk supported Barack Obama in 2008 and 2012, Hillary Clinton in 2016, Joe Biden in 2020, and Donald Trump in 2024. In the 2020 Democratic Party presidential primaries, Musk endorsed candidate Andrew Yang and expressed support for Yang's proposed universal basic income, and endorsed Kanye West's 2020 presidential campaign. In 2021, Musk publicly expressed opposition to the Build Back Better Act, a $3.5 trillion legislative package endorsed by Joe Biden that ultimately failed to pass due to unanimous opposition from congressional Republicans and several Democrats. In 2022, gave over $50 million to Citizens for Sanity, a conservative political action committee. In 2023, he supported Republican Ron DeSantis for the 2024 U.S. presidential election, giving $10 million to his campaign, and hosted DeSantis's campaign announcement on a Twitter Spaces event. From June 2023 to January 2024, Musk hosted a bipartisan set of X Spaces with Republican and Democratic candidates, including Robert F. Kennedy Jr., Vivek Ramaswamy, and Dean Phillips. In October 2025, former vice-president Kamala Harris commented that it was a mistake from the Democratic side to not invite Musk to a White House electric vehicle event organized in August 2021 and featuring executives from General Motors, Ford and Stellantis, despite Tesla being "the major American manufacturer of extraordinary innovation in this space." Fortune remarked that this was a nod to United Auto Workers and organized labor. Harris said presidents should put aside political loyalties when it came to recognizing innovation, and guessed that the non-invitation impacted Musk's perspective. Fortune noted that, at the time, Musk said, "Yeah, seems odd that Tesla wasn't invited." A month later, he criticized Biden as "not the friendliest administration." Jacob Silverman, author of the book Gilded Rage: Elon Musk and the Radicalization of Silicon Valley, said that the tech industry represented by Musk, Thiel, Andreessen and other capitalists, actually flourished under Biden, but the tech leaders chose Trump for their common ground on cultural issues. By early 2024, Musk had become a vocal and financial supporter of Donald Trump. In July 2024, minutes after the attempted assassination of Donald Trump, Musk endorsed him for president saying; "I fully endorse President Trump and hope for his rapid recovery." During the presidential campaign, Musk joined Trump on stage at a campaign rally, and during the campaign promoted conspiracy theories and falsehoods about Democrats, election fraud and immigration, in support of Trump. Musk was the largest individual donor of the 2024 election. In 2025, Musk contributed $19 million to the Wisconsin Supreme Court race, hoping to influence the state's future redistricting efforts and its regulations governing car manufacturers and dealers. In 2023, Musk said he shunned the World Economic Forum because it was boring. The organization commented that they had not invited him since 2015. He has participated in Dialog, dubbed "Tech Bilderberg" and organized by Peter Thiel and Auren Hoffman, though. Musk's international political actions and comments have come under increasing scrutiny and criticism, especially from the governments and leaders of France, Germany, Norway, Spain and the United Kingdom, particularly due to his position in the U.S. government as well as ownership of X. An NBC News analysis found he had boosted far-right political movements to cut immigration and curtail regulation of business in at least 18 countries on six continents since 2023. During his speech after the second inauguration of Donald Trump, Musk twice made a gesture interpreted by many as a Nazi or a fascist Roman salute.[e] He thumped his right hand over his heart, fingers spread wide, and then extended his right arm out, emphatically, at an upward angle, palm down and fingers together. He then repeated the gesture to the crowd behind him. As he finished the gestures, he said to the crowd, "My heart goes out to you. It is thanks to you that the future of civilization is assured." It was widely condemned as an intentional Nazi salute in Germany, where making such gestures is illegal. The Anti-Defamation League said it was not a Nazi salute, but other Jewish organizations disagreed and condemned the salute. American public opinion was divided on partisan lines as to whether it was a fascist salute. Musk dismissed the accusations of Nazi sympathies, deriding them as "dirty tricks" and a "tired" attack. Neo-Nazi and white supremacist groups celebrated it as a Nazi salute. Multiple European political parties demanded that Musk be banned from entering their countries. The concept of DOGE emerged in a discussion between Musk and Donald Trump, and in August 2024, Trump committed to giving Musk an advisory role, with Musk accepting the offer. In November and December 2024, Musk suggested that the organization could help to cut the U.S. federal budget, consolidate the number of federal agencies, and eliminate the Consumer Financial Protection Bureau, and that its final stage would be "deleting itself". In January 2025, the organization was created by executive order, and Musk was designated a "special government employee". Musk led the organization and was a senior advisor to the president, although his official role is not clear. In sworn statement during a lawsuit, the director of the White House Office of Administration stated that Musk "is not an employee of the U.S. DOGE Service or U.S. DOGE Service Temporary Organization", "is not the U.S. DOGE Service administrator", and has "no actual or formal authority to make government decisions himself". Trump said two days later that he had put Musk in charge of DOGE. A federal judge has ruled that Musk acted as the de facto leader of DOGE. Musk's role in the second Trump administration, particularly in response to DOGE, has attracted public backlash. He was criticized for his treatment of federal government employees, including his influence over the mass layoffs of the federal workforce. He has prioritized secrecy within the organization and has accused others of violating privacy laws. A Senate report alleged that Musk could avoid up to $2 billion in legal liability as a result of DOGE's actions. In May 2025, Bill Gates accused Musk of "killing the world's poorest children" through his cuts to USAID, which modeling by Boston University estimated had resulted in 300,000 deaths by this time, most of them of children. By November 2025, the estimated death toll had increased to 400,000 children and 200,000 adults. Musk announced on May 28, 2025, that he would depart from the Trump administration as planned when the special government employee's 130 day deadline expired, with a White House official confirming that Musk's offboarding from the Trump administration was already underway. His departure was officially confirmed during a joint Oval Office press conference with Trump on May 30, 2025. @realDonaldTrump is in the Epstein files. That is the real reason they have not been made public. June 5, 2025 After leaving office, Musk criticized the Trump administration's Big Beautiful Bill, calling it a "disgusting abomination" due to its provisions increasing the deficit. A feud began between Musk and Trump, with its most notable event being Musk alleging Trump had ties to sex offender Jeffrey Epstein on X (formerly Twitter) on June 5, 2025. Trump responded on Truth Social stating that Musk went "CRAZY" after the "EV Mandate" was purportedly taken away and threatened to cut Musk's government contracts. Musk then called for a third Trump impeachment. The next day, Trump stated that he did not wish to reconcile with Musk, and added that Musk would face "very serious consequences" if he funds Democratic candidates. On June 11, Musk publicly apologized for the tweets against Trump, saying they "went too far". Views November 6, 2022 Rejecting the conservative label, Musk has described himself as a political moderate, even as his views have become more right-wing over time. His views have been characterized as libertarian and far-right, and after his involvement in European politics, they have received criticism from world leaders such as Emmanuel Macron and Olaf Scholz. Within the context of American politics, Musk supported Democratic candidates up until 2022, at which point he voted for a Republican for the first time. He has stated support for universal basic income, gun rights, freedom of speech, a tax on carbon emissions, and H-1B visas. Musk has expressed concern about issues such as artificial intelligence (AI) and climate change, and has been a critic of wealth tax, short-selling, and government subsidies. An immigrant himself, Musk has been accused of being anti-immigration, and regularly blames immigration policies for illegal immigration. He is also a pronatalist who believes population decline is the biggest threat to civilization, and identifies as a cultural Christian. Musk has long been an advocate for space colonization, especially the colonization of Mars. He has repeatedly pushed for humanity colonizing Mars, in order to become an interplanetary species and lower the risks of human extinction. Musk has promoted conspiracy theories and made controversial statements that have led to accusations of racism, sexism, antisemitism, transphobia, disseminating disinformation, and support of white pride. While describing himself as a "pro-Semite", his comments regarding George Soros and Jewish communities have been condemned by the Anti-Defamation League and the Biden White House. Musk was criticized during the COVID-19 pandemic for making unfounded epidemiological claims, defying COVID-19 lockdowns restrictions, and supporting the Canada convoy protest against vaccine mandates. He has amplified false claims of white genocide in South Africa. Musk has been critical of Israel's actions in the Gaza Strip during the Gaza war, praised China's economic and climate goals, suggested that Taiwan and China should resolve cross-strait relations, and was described as having a close relationship with the Chinese government. In Europe, Musk expressed support for Ukraine in 2022 during the Russian invasion, recommended referendums and peace deals on the annexed Russia-occupied territories, and supported the far-right Alternative for Germany political party in 2024. Regarding British politics, Musk blamed the 2024 UK riots on mass migration and open borders, criticized Prime Minister Keir Starmer for what he described as a "two-tier" policing system, and was subsequently attacked as being responsible for spreading misinformation and amplifying the far-right. He has also voiced his support for far-right activist Tommy Robinson and pledged electoral support for Reform UK. In February 2026, Musk described Spanish Prime Minister Pedro Sánchez as a "tyrant" following Sánchez's proposal to prohibit minors under the age of 16 from accessing social media platforms. Legal affairs In 2018, Musk was sued by the U.S. Securities and Exchange Commission (SEC) for a tweet stating that funding had been secured for potentially taking Tesla private.[f] The securities fraud lawsuit characterized the tweet as false, misleading, and damaging to investors, and sought to bar Musk from serving as CEO of publicly traded companies. Two days later, Musk settled with the SEC, without admitting or denying the SEC's allegations. As a result, Musk and Tesla were fined $20 million each, and Musk was forced to step down for three years as Tesla chairman but was able to remain as CEO. Shareholders filed a lawsuit over the tweet, and in February 2023, a jury found Musk and Tesla not liable. Musk has stated in interviews that he does not regret posting the tweet that triggered the SEC investigation. In 2019, Musk stated in a tweet that Tesla would build half a million cars that year. The SEC reacted by asking a court to hold him in contempt for violating the terms of the 2018 settlement agreement. A joint agreement between Musk and the SEC eventually clarified the previous agreement details, including a list of topics about which Musk needed preclearance. In 2020, a judge blocked a lawsuit that claimed a tweet by Musk regarding Tesla stock price ("too high imo") violated the agreement. Freedom of Information Act (FOIA)-released records showed that the SEC concluded Musk had subsequently violated the agreement twice by tweeting regarding "Tesla's solar roof production volumes and its stock price". In October 2023, the SEC sued Musk over his refusal to testify a third time in an investigation into whether he violated federal law by purchasing Twitter stock in 2022. In February 2024, Judge Laurel Beeler ruled that Musk must testify again. In January 2025, the SEC filed a lawsuit against Musk for securities violations related to his purchase of Twitter. In January 2024, Delaware judge Kathaleen McCormick ruled in a 2018 lawsuit that Musk's $55 billion pay package from Tesla be rescinded. McCormick called the compensation granted by the company's board "an unfathomable sum" that was unfair to shareholders. The Delaware Supreme Court overturned McCormick's decision in December 2025, restoring Musk's compensation package and awarding $1 in nominal damages. Personal life Musk became a U.S. citizen in 2002. From the early 2000s until late 2020, Musk resided in California, where both Tesla and SpaceX were founded. He then relocated to Cameron County, Texas, saying that California had become "complacent" about its economic success. While hosting Saturday Night Live in 2021, Musk stated that he has Asperger syndrome (an outdated term for autism spectrum disorder). When asked about his experience growing up with Asperger's syndrome in a TED2022 conference in Vancouver, Musk stated that "the social cues were not intuitive ... I would just tend to take things very literally ... but then that turned out to be wrong — [people were not] simply saying exactly what they mean, there's all sorts of other things that are meant, and [it] took me a while to figure that out." Musk suffers from back pain and has undergone several spine-related surgeries, including a disc replacement. In 2000, he contracted a severe case of malaria while on vacation in South Africa. Musk has stated he uses doctor-prescribed ketamine for occasional depression and that he doses "a small amount once every other week or something like that"; since January 2024, some media outlets have reported that he takes ketamine, marijuana, LSD, ecstasy, mushrooms, cocaine and other drugs. Musk at first refused to comment on his alleged drug use, before responding that he had not tested positive for drugs, and that if drugs somehow improved his productivity, "I would definitely take them!". The New York Times' investigations revealed Musk's overuse of ketamine and numerous other drugs, as well as strained family relationships and concerns from close associates who have become troubled by his public behavior as he became more involved in political activities and government work. According to The Washington Post, President Trump described Musk as "a big-time drug addict". Through his own label Emo G Records, Musk released a rap track, "RIP Harambe", on SoundCloud in March 2019. The following year, he released an EDM track, "Don't Doubt Ur Vibe", featuring his own lyrics and vocals. Musk plays video games, which he stated has a "'restoring effect' that helps his 'mental calibration'". Some games he plays include Quake, Diablo IV, Elden Ring, and Polytopia. Musk once claimed to be one of the world's top video game players but has since admitted to "account boosting", or cheating by hiring outside services to achieve top player rankings. Musk has justified the boosting by claiming that all top accounts do it so he has to as well to remain competitive. In 2024 and 2025, Musk criticized the video game Assassin's Creed Shadows and its creator Ubisoft for "woke" content. Musk posted to X that "DEI kills art" and specified the inclusion of the historical figure Yasuke in the Assassin's Creed game as offensive; he also called the game "terrible". Ubisoft responded by saying that Musk's comments were "just feeding hatred" and that they were focused on producing a game not pushing politics. Musk has fathered at least 14 children, one of whom died as an infant. The Wall Street Journal reported in 2025 that sources close to Musk suggest that the "true number of Musk's children is much higher than publicly known". He had six children with his first wife, Canadian author Justine Wilson, whom he met while attending Queen's University in Ontario, Canada; they married in 2000. In 2002, their first child Nevada Musk died of sudden infant death syndrome at the age of 10 weeks. After his death, the couple used in vitro fertilization (IVF) to continue their family; they had twins in 2004, followed by triplets in 2006. The couple divorced in 2008 and have shared custody of their children. The elder twin he had with Wilson came out as a trans woman and, in 2022, officially changed her name to Vivian Jenna Wilson, adopting her mother's surname because she no longer wished to be associated with Musk. Musk began dating English actress Talulah Riley in 2008. They married two years later at Dornoch Cathedral in Scotland. In 2012, the couple divorced, then remarried the following year. After briefly filing for divorce in 2014, Musk finalized a second divorce from Riley in 2016. Musk then dated the American actress Amber Heard for several months in 2017; he had reportedly been "pursuing" her since 2012. In 2018, Musk and Canadian musician Grimes confirmed they were dating. Grimes and Musk have three children, born in 2020, 2021, and 2022.[g] Musk and Grimes originally gave their eldest child the name "X Æ A-12", which would have violated California regulations as it contained characters that are not in the modern English alphabet; the names registered on the birth certificate are "X" as a first name, "Æ A-Xii" as a middle name, and "Musk" as a last name. They received criticism for choosing a name perceived to be impractical and difficult to pronounce; Musk has said the intended pronunciation is "X Ash A Twelve". Their second child was born via surrogacy. Despite the pregnancy, Musk confirmed reports that the couple were "semi-separated" in September 2021; in an interview with Time in December 2021, he said he was single. In October 2023, Grimes sued Musk over parental rights and custody of X Æ A-Xii. Elon Musk has taken X Æ A-Xii to multiple official events in Washington, D.C. during Trump's second term in office. Also in July 2022, The Wall Street Journal reported that Musk allegedly had an affair with Nicole Shanahan, the wife of Google co-founder Sergey Brin, in 2021, leading to their divorce the following year. Musk denied the report. Musk also had a relationship with Australian actress Natasha Bassett, who has been described as "an occasional girlfriend". In October 2024, The New York Times reported Musk bought a Texas compound for his children and their mothers, though Musk denied having done so. Musk also has four children with Shivon Zilis, director of operations and special projects at Neuralink: twins born via IVF in 2021, a child born in 2024 via surrogacy and a child born in 2025.[h] On February 14, 2025, Ashley St. Clair, an influencer and author, posted on X claiming to have given birth to Musk's son Romulus five months earlier, which media outlets reported as Musk's supposed thirteenth child.[i] On February 22, 2025, it was reported that St Clair had filed for sole custody of her five-month-old son and for Musk to be recognised as the child's father. On March 31, 2025, Musk wrote that, while he was unsure if he was the father of St. Clair's child, he had paid St. Clair $2.5 million and would continue paying her $500,000 per year.[j] Later reporting from the Wall Street Journal indicated that $1 million of these payments to St. Clair were structured as a loan. In 2014, Musk and Ghislaine Maxwell appeared together in a photograph taken at an Academy Awards after-party, which Musk later described as a "photobomb". The January 2026 Epstein files contain emails between Musk and Epstein from 2012 to 2013, after Epstein's first conviction. Emails released on January 30, 2026, indicated that Epstein invited Musk to visit his private island on multiple occasions. The correspondence showed that while Epstein repeatedly encouraged Musk to attend, Musk did not visit the island. In one instance, Musk discussed the possibility of attending a party with his then-wife Talulah Riley and asked which day would be the "wildest party"; according to the emails, the visit did not take place after Epstein later cancelled the plans.[k] On Christmas day in 2012, Musk emailed Epstein asking "Do you have any parties planned? I’ve been working to the edge of sanity this year and so, once my kids head home after Christmas, I really want to hit the party scene in St Barts or elsewhere and let loose. The invitation is much appreciated, but a peaceful island experience is the opposite of what I’m looking for". Epstein replied that the "ratio on my island" might make Musk's wife uncomfortable to which Musk responded, "Ratio is not a problem for Talulah". On September 11, 2013, Epstein sent an email asking Musk if he had any plans for coming to New York for the opening of the United Nations General Assembly where many "interesting people" would be coming to his house to which Musk responded that "Flying to NY to see UN diplomats do nothing would be an unwise use of time". Epstein responded by stating "Do you think i am retarded. Just kidding, there is no one over 25 and all very cute." Musk has denied any close relationship with Epstein and described him as a "creep" who attempted to ingratiate himself with influential people. When Musk was asked in 2019 if he introduced Epstein to Mark Zuckerberg, Musk responded: "I don’t recall introducing Epstein to anyone, as I don’t know the guy well enough to do so." The released emails nonetheless showed cordial exchanges on a range of topics, including Musk's inquiry about parties on the island. The correspondence also indicated that Musk suggested hosting Epstein at SpaceX, while Epstein separately discussed plans to tour SpaceX and bring "the girls", though there is no evidence that such a visit occurred. Musk has described the release of the files a "distraction", later accusing the second Trump administration of suppressing them to protect powerful individuals, including Trump himself.[l] Wealth Elon Musk is the wealthiest person in the world, with an estimated net worth of US$690 billion as of January 2026, according to the Bloomberg Billionaires Index, and $852 billion according to Forbes, primarily from his ownership stakes in SpaceX and Tesla. Having been first listed on the Forbes Billionaires List in 2012, around 75% of Musk's wealth was derived from Tesla stock in November 2020, although he describes himself as "cash poor". According to Forbes, he became the first person in the world to achieve a net worth of $300 billion in 2021; $400 billion in December 2024; $500 billion in October 2025; $600 billion in mid-December 2025; $700 billion later that month; and $800 billion in February 2026. In November 2025, a Tesla pay package worth potentially $1 trillion for Musk was approved, which he is to receive over 10 years if he meets specific goals. Public image Although his ventures have been highly influential within their separate industries starting in the 2000s, Musk only became a public figure in the early 2010s. He has been described as an eccentric who makes spontaneous and impactful decisions, while also often making controversial statements, contrary to other billionaires who prefer reclusiveness to protect their businesses. Musk's actions and his expressed views have made him a polarizing figure. Biographer Ashlee Vance described people's opinions of Musk as polarized due to his "part philosopher, part troll" persona on Twitter. He has drawn denouncement for using his platform to mock the self-selection of personal pronouns, while also receiving praise for bringing international attention to matters like British survivors of grooming gangs. Musk has been described as an American oligarch due to his extensive influence over public discourse, social media, industry, politics, and government policy. After Trump's re-election, Musk's influence and actions during the transition period and the second presidency of Donald Trump led some to call him "President Musk", the "actual president-elect", "shadow president" or "co-president". Awards for his contributions to the development of the Falcon rockets include the American Institute of Aeronautics and Astronautics George Low Transportation Award in 2008, the Fédération Aéronautique Internationale Gold Space Medal in 2010, and the Royal Aeronautical Society Gold Medal in 2012. In 2015, he received an honorary doctorate in engineering and technology from Yale University and an Institute of Electrical and Electronics Engineers Honorary Membership. Musk was elected a Fellow of the Royal Society (FRS) in 2018.[m] In 2022, Musk was elected to the National Academy of Engineering. Time has listed Musk as one of the most influential people in the world in 2010, 2013, 2018, and 2021. Musk was selected as Time's "Person of the Year" for 2021. Then Time editor-in-chief Edward Felsenthal wrote that, "Person of the Year is a marker of influence, and few individuals have had more influence than Musk on life on Earth, and potentially life off Earth too."

Contents SimFiT Simfit is a free open-source Windows package for simulation, curve fitting, statistics, and plotting, using a library of models or user-defined mathematical equations. Simfit has been developed by Bill Bardsley of the University of Manchester. Although it is written for Windows, it can easily be installed and used on Linux machines via WINE. Simfit is developed using Silverfrost Limited's FTN95 Fortran Compiler and is currently featured on their website as a showcased application. The graphical functionality in Simfit has been released as a Fortran library called Simdem which allows the programmer to produce charts and graphs with just a few lines of Fortran. A version of Simdem is shipped with the Windows version of the NAG Fortran Builder. A Spanish-language version of Simfit is maintained by a team in Salamanca. At Version 8.1.1 a simplified version of simfit called sv_simfit designed for first-time users is bundled with the main simfit package.
