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 French science fiction French science fiction is a substantial genre of French literature. It remains an active and productive genre which has evolved in conjunction with anglophone science fiction and other French and international literature. History As far back as the 17th century, space exploration and aliens can be found in Cyrano de Bergerac's Comical History of the States and Empires of the Moon (1657) and Bernard Le Bovier de Fontenelle's Entretien sur la Pluralité des Mondes (1686). Voltaire's 1752 short stories Micromégas and Plato's Dream are particularly prophetic of the future of science fiction. Also worthy of note are Simon Tyssot de Patot's Voyages et Aventures de Jacques Massé (1710), which features a Lost World, La Vie, Les Aventures et Le Voyage de Groenland du Révérend Père Cordelier Pierre de Mésange (1720), which features a Hollow Earth, Louis-Sébastien Mercier's L'An 2440 (1771), which depicts a future France, and Nicolas-Edmé Restif de la Bretonne's La Découverte Australe par un Homme Volant (1781) known for his prophetic inventions. Other notable proto-science fiction authors and works of the 18th and 19th century include: However, modern French science fiction, and arguably science fiction as a whole, begins with Jules Verne (1828–1905), the author of many of the classics of science fiction. The first few decades of French science fiction produced several renowned names of literature, the Scientific Marvelous. Not only Jules Verne, but also: After H. G. Wells' The Time Machine was translated into French by Henry D. Davray in 1895 as the first of his works, succeeded soon by other translations of his stories, influencing French science fiction writers such as Maurice Renard. World War I brought an end to this early period. While the rapid development of science and technology during the late 19th century motivated the optimistic works of early science fiction authors, the horrors of industrialised warfare and specifically the application of advanced technologies in such a destructive manner made many later French authors more pessimistic about the potential of technological development. Between the two world wars, Rosny aîné published his masterpiece Les Navigateurs de l'Infini (1924), in which he invented the word "astronautique". There were a few notable new authors during the period: Until the late 1950s, relatively little French science fiction was published, and what was published was often very pessimistic about the future of humanity, and was frequently not advertised as "science fiction" at all. René Barjavel's Ravage (1943) and Pierre Boulle's Planet of the Apes (1963) are examples well known. This period of decrease of French science fiction (abbreviated SF) is considered by many to be a "golden age" of English-language and particularly American science fiction. When French science fiction began reappearing strongly after World War II, it was the themes and styles of Anglophone science fiction which served as an inspiration for new works. The first genre magazine, Fiction – at first a translation of the American Magazine of Fantasy & Science Fiction – began appearing during 1953. The major genre imprint of the 1950s and '60s publishing translations of American novels was Le Rayon Fantastique published by Hachette and Gallimard, and edited by George Gallet and Stephen Spriel. Nevertheless, Le Rayon Fantastique helped begin the careers of a number of French authors: During 1951, publisher Fleuve Noir initiated Anticipation, a paperback series devoted mostly to French authors which released a steady series of pulp-like novels. Among its authors were: Later, many major names of French science fiction were printed first by that company. Another series, Présence du Futur, was initiated during 1954 by publisher Denoël. Among its authors were: During this era, there was very little mainstream critical interest for French SF. French cinema, however, proved to be more successful for science fiction. Jean-Luc Godard's 1965 movie Alphaville—- a thriller and satire of French politics—- was the first major example of French "New Wave" science fiction. Unlike American science fiction, space travel was not the major theme for the post-1968 French authors. A new generation of French writers, who had few memories of the horrors of the past two generations, were inspired by the transformation of France during the post-war era. Especially after May 1968, French SF authors wrote about political and social themes in their works. Authors like Michel Jeury, Jean-Pierre Andrevon and Philippe Curval began to attract acclaim for their redevelopment of a genre which, at the time, was still considered primarily a juvenile entertainment. During the 1970s, comics began to be important for French SF. Métal hurlant—- the French magazine that was imitated as the American magazine Heavy Metal –- began developing the possibilities of science fiction as a source for cartoons. Graphic novels are now a major— if not the major— outlet for French science fiction production today. During the 1980s, French authors began to consider science fiction as appropriate for experimental literature. The influence of postmodernism on literature and the development of cyberpunk themes catalysed a new body of French SF, near the end of the decade: the so-called "Lost Generation" (represented by such writers as Claude Ecken, Michel Pagel, Jean-Marc Ligny or Roland C. Wagner) At present, French SF is particularly well represented by graphic novels, and a number of titles are printed annually. As in most of the developed world, magazine culture has decreased dramatically because of the internet, but a number of French SF magazines remain in print, including Bifrost, Galaxies and Solaris. Despite the space opera revival of the beginning of the 1990s (Ayerdhal, Serge Lehman, Pierre Bordage, Laurent Genefort) the influence from English language science fiction and movies has diminished considerably since the "Lost Generation", while the influence of animation, video games and other international science fiction traditions (German, Italian) has increased. The influence of Japanese manga and anime has also been particularly noticeable during recent years for graphic formats. Other notable French science fiction authors, post-World War II Literary awards The Prix Rosny-Aîné is an annual award for French-language science fiction. Other Awards for French-language science fiction (non-exclusively) include or have includes the Prix Apollo (1972–1990), the Prix Bob Morane (1999– ), the Grand Prix de l'Imaginaire (1974– ), the Prix Julia Verlanger (1986– ), the Prix Jules Verne (1927–1933; 1958–1963), the Prix Ozone (1977–2000) and the Prix Tour Eiffel (1997–2002).

Contents Minoru Arakawa Minoru Arakawa (荒川 實, Arakawa Minoru; born September 3, 1946) is a Japanese businessman best known as the founder and former president of Nintendo of America, and the co-founder of Tetris Online, Inc. Biography Minoru Arakawa was born on 3 September 1946 in Kyoto, Japan, the second son of Waichiro Arakawa and Michi Ishihara. His elder brother, Shoichi, later took over the family business. His sister married a professor of medicine. Waichiro was the manager of Arakawa Textiles, and was more concerned with maintaining positive relationships with suppliers and customers than growing the company. Michi was an artist, who spent afternoons in the family garden or her studio; her paintings were hung at their family home. Arakawa's family was wealthy; the total real estate of Arakawa's family combined was about one-fifth of the downtown district in Kyoto. Arakawa began studying at Kyoto University in 1964, taking general classes for the first two years before focusing on civil engineering. He graduated with a master's degree in 1969, before moving to Boston in 1971 to continue studying civil engineering at the Massachusetts Institute of Technology. He witnessed several protests against the United States involvement in the Vietnam War, but did not participate. Arakawa graduated MIT with a second master's degree in 1972. Following a conversation on campus with a group of young Japanese businessmen, he decided to try to find work with a trading company. Upon returning to Japan, he was hired by Marubeni, a company in Tokyo that developed hotels and office buildings. At a Christmas party in Kyoto, Arakawa met Yoko Yamauchi, daughter of Nintendo president Hiroshi Yamauchi. They married in November 1973. Arakawa, along with his wife and three-year-old daughter Maki, moved to Vancouver, Canada in 1977 for work. A second daughter, Masayo, was born in 1978. Hiroshi Yamauchi offered Arakawa the job of establishing Nintendo of America; while Yoko opposed the position, having seen the impact of the company on her father's life, Arakawa accepted the offer. Arakawa and his wife established an office in Manhattan in 1980, and Arakawa became the company's first president. He had modest success at importing arcade games from the parent company in Japan, and then betting his small company on a huge order of Radar Scope with disastrous reception. This failure prompted the parent company's innovative creation of Donkey Kong, and he converted his warehouse full of useless Radar Scope units into a phenomenally successful inventory of Donkey Kong units. This is the debut of Mario, who Arakawa is credited with naming after the office's Italian landlord Mario Segale. Starting in 1985, he and Howard Lincoln were instrumental in rebuilding the North American video game industry from the crash of 1983, with the launch of the Nintendo Entertainment System. Arakawa also hired Howard Phillips, who would be invaluable to the creation of the Nintendo Power magazine. In January 2002, Arakawa resigned as NoA president and was succeeded by Tatsumi Kimishima, former chief financial officer of Nintendo's Pokémon subsidiary. Arakawa won a lifetime achievement award in February 2007 at the Interactive Achievement Awards. In January 2006, Arakawa co-founded Tetris Online, Inc. with Henk Rogers and Tetris creator Alexey Pajitnov, which developed various games for Nintendo DS, Wii, iOS, and Facebook. Arakawa served as the president of Tetris Online, Inc. until March 2013. He is also an advisor to Avatar Reality. Arakawa is played by Ken Yamamura in the 2023 movie Tetris. References |

Ali Partovi, the veteran investor and CEO of venture firm Neo, wants to offer the mentorship and community of one of the most elite accelerator programs — without forcing the best up-and-coming tech leaders to hand over 7% or sometimes 10% of their company before they’ve even started. Partovi, who is known for his early investments in Facebook, Cursor, and Kalshi, has just introduced Neo Residency, a new, competitively structured program that combines the firm’s now four-year-old accelerator with a track for current college students. The terms that Neo Residency offers are so founder-friendly as to be “not even comparable to any other accelerator,” Partovi told TechCrunch. For the cohort of 12 to 15 startups entering the program this summer, Neo will invest $750,000 via an uncapped SAFE — a contract that gives an investor future equity in exchange for money now, with no ceiling on the valuation used to calculate that stake. Unlike the fixed-percentage deals typical of other accelerators, Neo won’t receive its equity until the company’s next formal funding round, and even then, the dilution is tied to valuation. If a startup raises its next round at a $15 million valuation, Neo’s stake will be 5%, but if that valuation hits $100 million, the firm’s ownership drops to just 0.75%. “We take the risk up front, so this is extremely favorable to startups,” Partovi said. In comparison, Y Combinator typically takes a fixed 7% of the company for $125,000, with another $375,000 invested on an uncapped MFN — or most-favored nation — SAFE, a clause that ensures early investors get terms at least as good as those given to later ones. Meanwhile, Andreessen Horowitz’s Speedrun program typically invests $500,000 in exchange for 10% of the startup via a SAFE note, and another $500,000 if the next round is raised within 18 months at whatever terms are agreed to by the other investors. “We’re offering a deal so great that it’s appropriate even for founders who are not even considering any other accelerator,” Partovi said. The lower equity cost is only part of Neo Residency’s appeal. The founders will work for three months at Neo’s offices in San Francisco’s Jackson Square district, participate in a two-week bootcamp in the Oregon mountains, and be mentored by about 30 experienced operators, including Russell Kaplan, president of Cognition, and Fuzzy Khosrowshahi, CTO of Notion (and the creator of Google Sheets and also Partovi’s uncle). But the program’s main draw is its prestige: Seed and Series A investors generally have great respect for founders handpicked by Partovi. “The one [accelerator] I like right now that has very high signal, and every founder I met there is just wicked smart, is Neo,” Wesley Chan, co-founder and managing partner of FPV Ventures, said onstage at 2025 TechCrunch Disrupt. Startups that have gone through the program include Moment, a fintech company that has raised $56 million from investors like Andreessen Horowitz, and Anterior, a healthcare AI startup backed by NEA and Sequoia. The Neo Residency will also select five to eight students — either as individuals or small teams — who will receive a $40,000, no-strings-attached grant to take a semester off to work on a project. While there is no requirement to drop out or start a formal company immediately, Partovi said he hopes the students will catch the entrepreneurial bug and, when they eventually launch a startup, turn to Neo for funding. Neo is keeping the program small and elite: It will cap its two annual cohorts at 20 teams each, consisting of a mix of active startups and student projects. Why is Neo offering such generous terms? “We have more confidence in our ability to attract and pick out future superstars than ever before,” Partovi said. His track record suggests that confidence is well-founded. He famously met Cursor co-founder Michael Truell while Truell was still an MIT student and later wrote one of the first checks into the AI coding startup, now valued at nearly $30 billion.

Contents Muslim conquest of Syria Byzantine Empire Sasanian Empire Caucasus Other regions Syria Egypt North Africa Asia Minor Sicily Eastern Mediterranean Byzantine reconquest The Muslim conquest of Syria (Arabic: فَتْحُ الشَّام, romanized: Fatḥ al-šām; lit. 'Conquest of Syria'),[a] or the Arab conquest of Syria, was the conquest of Byzantine Syria by the Rashidun Caliphate that took place between 634–638 CE as part of the Arab–Byzantine wars and the wider Muslim conquests. Clashes between the Muslims and the Byzantines on the southern Levantine borders of the Byzantine Empire had occurred previously during the lifetime of Muhammad, with the Battle of Muʿtah in 629 CE. However, the actual conquest did not begin until 634, two years after Muhammad's death. It was led by the first two Rashidun caliphs who succeeded Muhammad: Abu Bakr and Umar ibn al-Khattab. During this time, Khalid ibn al-Walid was the most important commander of the Rashidun army. In the aftermath of the conquest, Syria was brought under Arab Muslim rule and developed into the provincial region of Bilad al-Sham. Background Syria had been under Roman rule for seven centuries prior to the Arab Muslim conquest and had been invaded by the Persian Sasanian Empire on a number of occasions during the 3rd, 6th and 7th centuries; it had also been subject to raids by the Sasanian Empire' Arab allies, the Lakhmids. During the Roman period, beginning after the fall of Jerusalem in the year 70, the entire region (Judea, Samaria, and the Galilee) was renamed Palaestina, subdivided into Diocese I and II. The Romans also renamed an area of land including the Negev, Sinai, and the west coast of the Arabian Peninsula as Palaestina Salutaris, sometimes called Palaestina III or Palaestina Tertia. Part of the area was ruled by the Arab vassal state of the Ghassanids' symmachos. During the last of the Roman-Persian Wars, beginning in 602, the Persians under Khosrau II had succeeded in occupying Syria, Palestine and Egypt for over a decade before being forced by the victories of Heraclius to conclude the peace of 628. Thus, on the eve of the Muslim conquests the Romans (or Byzantines as modern Western historians conventionally refer to Romans of this period) were still in the process of rebuilding their authority in these territories, which in some areas had been lost to them for almost twenty years. Politically, the Syrian region consisted of two provinces: Syria proper stretched from Antioch and Aleppo in the north to the top of the Dead Sea. To the west and south of the Dead Sea lay the province of Palestine. Byzantine Syria was mostly home to Aramaic and Greek speakers and a partly Arab population, especially in its eastern and southern parts. The Ghassanid tribe, who migrated from Yemen to Syria, converted to Christianity and served as foederati for the Eastern Roman empire like the Tanukh before them. Thereafter, they ruled a semi-autonomous state with their own king under Roman vassalage. The Ghassanid dynasty became one of the honoured princely dynasties of the Empire, with the Ghassanid king ruling over the Arabs in Jordan and Southern Syria from his capital at Bostra. The last of the Ghassanid kings, who ruled at the time of the Muslim invasion, was Jabala ibn al-Ayham. The Byzantine Emperor Heraclius, after re-capturing Syria from the Sassanians, set up new defense lines from Gaza to the south end of the Dead Sea. These lines were only designed to protect communications from bandits, and the bulk of the Byzantine defenses were concentrated in Northern Syria facing the traditional foes, the Sassanid Persians. The drawback of this defense line was that it enabled the Muslims, advancing from the desert in the south, to reach as far north as Gaza before meeting regular Byzantine troops. The 7th century was a time of rapid military change in the Byzantine Empire. The empire was certainly not in a state of collapse when it faced the new challenge from Arabia after being exhausted by recent Roman–Persian Wars, but utterly failed to tackle the challenge effectively. Military confrontations with the Byzantine Empire began during the lifetime of Muhammad. The Battle of Mu'tah was fought in September 629 near the village of Mu'tah, east of the Jordan River and Karak in Karak Governorate, between the forces of the Islamic prophet Muhammad and the forces of the Byzantine Empire and their Arab Christian Ghassanid vassals. In Islamic historical sources, the battle is usually described as the Muslims' attempt to take retribution against the Ghassanids after a Ghassanid official executed Muhammad's emissary who was en route to Bosra. During the battle the Muslim army was routed. After three Muslim leaders were killed, the command was given to Khalid ibn al-Walid and he succeeded in saving the rest of the forces. The surviving Muslim forces retreated to Medina. After the Farewell Pilgrimage in 632, Muhammad appointed Usama ibn Zayd as the commander of an expeditionary force which was to invade the region of Balqa in the Byzantine Empire. This expedition was known as the Expedition of Usama bin Zayd and its stated aim was to avenge the Muslim losses at the Battle of Mu'tah, in which Usama's father and Muhammad's former adopted son, Zayd ibn Harithah, had been killed. Usama's expedition in May/June 632 was successful and his army was the first Muslim force to successfully invade and raid Byzantine territory. Muhammad died in June 632, and Abu Bakr was appointed Caliph and political successor at Medina. Soon after Abu Bakr's succession, several Arab tribes revolted against him in the Ridda wars (Arabic for the Wars of Apostasy). The Campaign of the Apostasy was fought and completed during the eleventh year of the Hijri. The year 12 Hijri dawned, on 18 March 633, with Arabia united under the central authority of the Caliph at Medina. Whether Abu Bakr intended a full-out imperial conquest or not is hard to say; he did, however, set in motion a historical trajectory that in just a few short decades would lead to one of the largest empires in history, starting with a confrontation with the Persian Empire under the general Khalid ibn al-Walid. Historiography Despite the often contradictory early Islamic narratives of the conquest, the historian Fred Donner deemed it "possible to reconstruct the broad outlines" of the war. The course of the conquest is generally divided into three main phases. During the initial invasion in late 633–early 634, Muslim forces encountered local garrisons and conquered much of the southern, tribal Syrian countryside. The second phase in 634–636 saw the arrival of the prominent Arab general Khalid ibn al-Walid and the capture of major towns, eliciting increasingly stronger responses by the Byzantine emperor. In the ensuing major battles, the Byzantine imperial armies were decisively defeated. This breaking of imperial power in the region brought about the final phase, the occupation of Syria, from 637 to 647–648. This stage, in Donner's words, entailed "the rapid conquest of the remaining countryside not under the Muslims' control, especially in northern Syria, and the piecemeal reduction of individual Syrian towns, which had been left alone to resist the advancing Muslims". Initial invasion With the tribes of Arabia brought under Medina's control during the Ridda wars, Abu Bakr prepared and dispatched armies for the conquest of Byzantine Syria. The first of these armies was probably that of Khalid ibn Sa'id ibn al-As, an early companion of Muhammad. He was shortly after dismissed at the instigation of Umar for having opposed Abu Bakr's succession, with one set of early Muslim accounts placing this dismissal before his departure from Medina and the other once he reached the Tayma oasis on the approaches to Syria. At Tayma, he was supposedly reinforced with troops led by the commander al-Walid ibn Uqba, engaged with Arab allies of the Byzantines, and was defeated. In the Islamic calendar date of Rajab 12 AH (September 633) or the beginning of 13 AH (Spring 634),[b] Abu Bakr dispatched three or four armies to Syria led respectively by Amr ibn al-As, Shurahbil ibn Hasana, Yazid ibn Abi Sufyan, and Abu Ubayda ibn al-Jarrah, all of whom were companions of Muhammad and the first two veterans of the Ridda wars. The timing and order of each commander's deployment and whether they were independent of each other or if any held the high command at this stage is not clear. Each army took a separate route toward Syria. Amr embarked on the coastal road to Ayla before breaking northwest into the Negev Desert and toward Gaza. The other commanders took the road through Tabuk, with Shurahbil stopping in the area east of the Arabah Valley, Yazid terminating in the Balqa region east of the Dead Sea, and Abu Ubayda taking up position in the Golan Heights area. The 9th-century historian al-Baladhuri and modern scholarship in general dates Abu Ubayda's arrival in Syria to after Abu Bakr's death in 634 and as late as 636. According to narrative of the 8th-century historian al-Azdi, Abu Bakr instructed Yazid with ethical and operational instructions: When you meet the enemy, and God leads you to victory, do not manacle, mutilate, maim, or betray, and do not accuse [the defeated] of cowardice. Do not, you all, kill children, old men, or women; do not burn palm trees or uproot them; do not cut down fruitful trees; and do not slaughter cattle except for eating [them]. You will pass by people in their hermitages who claim to have secluded themselves for [worshipping] God; leave them to what they have secluded themselves for. You will also find others in the middle of whose heads Satan has taken up abode, as if the middles of their heads were the sand grouses' nests (afahīs al-qatā). Strike the nests which they have hollowed in their heads with swords until they turn repentantly to Islam, or until they bring tribute by hand and with humility. God will certainly support those who support Him and His Messengers in absentia (bi-al-ghayb). The authenticity of these instructions has been questioned by modern scholars. James Moreton Wackeley characterises it as a literary construct intended to idealise early Muslim leadership, while Albrecht Noth interprets such speeches as part of a wider tradition in which later transmitters reworked existing material to promote moral and legal norms, retroactively ascribing it to prominent early figures to strengthen its authority. Such interpretations are situated within a broader secular academic discourse that applies historical-critical methods to the Islamic tradition. The first encounter between the Muslims and Byzantines occurred at Dathin and Badan, near Gaza, where negotiations between Amr and the local Byzantine garrison commander broke down and gave way to a skirmish ending with Amr's defeat of the local garrison. While of minor consequence, news of the Arabs' victory at Dathin alerted the Byzantines to the entry of Muslim forces into Syria. Amr afterward set up headquarters at Ghamr al-Arabat, a location in the middle of the Arabah Valley. Credible details of the other commanders' activities is sparse, but a lieutenant of Abu Ubayda may have gained the surrender of a town called Ma'ab in the Balqa, Yazid may have succeeded against a Byzantine force in a minor clash in Palestine and Shurahbil oversaw activity against the pro-Byzantine Quda'a tribal group in his area of operations. Donner concludes that the operations in this phase of the Muslim campaigns, where urban centers and major agricultural areas were avoided, targeted the territories inhabited by nomadic and partly settled Arab tribes. Kennedy comments that at this point, "the Muslim attacks on Syria had amounted to little more than pinpricks along the frontiers". The goal of the Muslim state was probably to continue the process of subjugating all Arab tribes, which Medina had consistently viewed as posing threats to its power. Once the bulk of the tribes were under Muslim control, the Muslims could launch the major assaults against Syria's main armies and cities. Byzantine movements In the spring of 634, the prominent veteran commander of the Ridda wars Khalid ibn al-Walid was directed by Abu Bakr to leave his campaigning in the desert frontier of Iraq and join the Muslim armies in Syria. He embarked on an unconventional march across the Syrian Desert, including six days through a waterless trek. He managed the trek by increasing his camels' water intake, sealing their mouths to prevent them from eating, and slaughtering them for water as needed by his troops. He bested pro-Byzantine Arabs from the Bahra tribe in the vicinity of Palmyra. Afterward, on 24 April 634, he landed upon a group of pro-Byzantine Ghassanid Arabs celebrating Easter at the Marj Rahit meadow north of Damascus. His troops proceeded to raid the Ghouta gardens around the city. They then rendezvoused with Muslim forces positioned near Bosra, the capital of Arabia Province and a center of trade in the Hauran region south of Damascus which historically provided the nomadic Arabs with oil, wine and grain. Khalid was appointed to the supreme command of the Muslim armies in Syria by Abu Bakr or by the Muslim commanders already present. The Muslims besieged and captured Bosra in May, facing token resistance by its defenders. The city surrendered in a pact obliging its inhabitants to pay an annual poll tax, the jizya. Khalid and the other commanders moved to join Amr ibn al-As in southern Palestine to help him counter a large number of Byzantine troops mobilized against him. The ensuing Battle of Ajnadayn, fought at a site in the Wadi al-Simt valley southwest of Jerusalem, was the first major confrontation between the Muslims and the Byzantines. The two sides incurred significant losses, including several prominent Muslims and the Byzantine cubicularius, but the battle ended with the Byzantines routed. The battle is variously dated to July 634 or January 635. In the aftermath of Ajnadayn, Amr captured several towns in the interior of Palestine, including Sebastia, Nablus (Neapolis), Lydda, Yibna, Amwas (Emmaus-Nicopolis), Bayt Jibrin (Eleutheropolis) and Jaffa. Most of these towns fell after minor resistance, hence the scant information available about their captures in the sources. Remnants of the Byzantines from Ajnadayn regrouped to the northeast, in Pella ('Fahl' in Arabic), a town with a Byzantine garrison on the eastern bank of the River Jordan, across from Scythopolis ('Beisan' in Arabic). The Muslims pursued them there, encountering difficulty traversing the muddy grounds around Beisan with their horses, a result of floods from the breaking of the river banks by the Byzantines. The Muslims defeated the Byzantines, who incurred heavy casualties, at the Battle of Fahl and occupied the city in December 634 or January 635. They may have engaged with Byzantine troops in another battle at Marj al-Suffar, south of Damascus, in which the Muslims suffered heavy losses but drove the Byzantines off nonetheless. Marj al-Suffar is dated variously to March 635 or before Fahl, in July 634. From Fahl, the Muslims marched on Damascus, where the Byzantines there were joined by their comrades from the previous battles with the Muslims. They were under the command of Vahan. All the Muslim commanders participated in the siege of Damascus, each posted to one of the city's five gates, while a sixth unit was positioned at the village of Barzeh to intercept Byzantine reinforcements from the north. After a lengthy siege, Damascus capitulated in August or September 635. Although they disagree in the identities of the commanders, most of the Muslim accounts agree that Muslim forces breached one of the city gates, while on another side of the city, the local leaders opened a gate after negotiations with a different Muslim unit. The Muslim commanders ultimately met in the city center where they drafted a capitulation agreement with the inhabitants. Although several versions of the treaty were recorded in the early Muslim and Christian sources,[c] they generally concur that the inhabitants' lives, properties and churches were to be safeguarded, in return for their payment of the jizya (poll tax). Imperial properties were confiscated by the Muslims. The treaty probably served as the model for the capitulation agreements made throughout Syria, as well Iraq and Egypt, during the early Muslim conquests.[d] After Damascus, Muslim forces proceeded to capture Baalbek and then, after a months-long siege, occupied Homs in December 635 or January 636. Heraclius, who had been observing events from his base in Antioch, responded to the string of Muslim victories and occupations of major cities by mobilizing a massive force of Byzantine imperial troops, local garrisons from Antioch, Aleppo, Chalcis, Mesopotamia, Armenians under their commander Gregory, and Syrian Arab tribesmen under the Ghassanid chief Jabala ibn Ayham. The overall command of the Byzantines was held by the sacellarius and Vahan. This force's march south prompted the Muslims to abandon Homs, Baalbek and Damascus and regroup at Jabiya in the Golan Heights. The Byzantines took up position nearby, along the Ruqqad river, prompting the Muslims to set up camp at the adjoining Yarmuk River. This hilly area straddled the borders of four Byzantine provinces and served as the main pasture grounds for the Ghassanids. As the Byzantines advanced, the Muslims feigned retreat, inducing the Byzantines to assault the Muslims' camp at Dayr Ayyub. This left the Byzantines' left flank vulnerable and Muslim forces used the wide gap and poor coordination between the Byzantine cavalry and infantry to inflict heavy casualties on the latter. Byzantine forces subsequently fled for safety to a site between the Ruqqad and Allan streams, but the site's only viable exit, the bridge over the Ruqqad, was captured in a night raid by Khalid's cavalry. The Muslims afterward assaulted the Byzantines' encampments between the two streams and at the village of Yaqusa on the edge of the Golan, where most of the Byzantine troops were slain, though many Arab Christian auxiliaries had deserted by that point. The Muslim victory at the Yarmuk destroyed the main Byzantine army in Syria and ended the Byzantines' will to confront the Muslims on the field. It sealed Muslim gains in Palestine and Transjordan and paved the way to their quick reoccupation of Damascus and the Beqaa Valley. In the assessment of historian John Jandora, Yarmuk was one of "the most important battles of World History", ultimately leading to Muslim victories which expanded the Caliphate between the Pyrenees mountains and Central Asia. Occupation of Syria As the Muslims no longer had to confront Byzantine standing armies after Yarmuk, the Muslim army in Syria split into smaller forces and proceeded to occupy Syria's cities. In this phase of the conquest, the main resistance against the Muslims were Byzantine garrisons and local militias. Probably after Yarmuk, Khalid was replaced by Abu Ubayda as the overall commander of the Muslim forces in Syria, with Khalid becoming one of his lieutenant commanders. Abu Ubayda and his lieutenants besieged and recaptured Homs, making it the base of operations for the conquest of northern Syria. Abu Ubayda and/or his lieutenants proceeded to capture Qinnasrin (Chalcis), Aleppo and Antioch from their defenders in relatively quick succession. The accounts about events in northern Syria are especially divergent. Heraclius may have deployed a force under a general, Minas, which was defeated by the Muslims in the plain between Aleppo and Qinnasrin, before or after the Muslims' capture of those cities. A Byzantine army, swelled by conscripts from several cities in Upper Mesopotamia (the 'Jazira' in Arabic), may have besieged Homs, prompting Abu Ubayda to recall his lieutenants and their armies in the north to buttress the defense of the city. As other Muslim forces proceeded east against the cities of the Jazira, the troops from those areas abandoned the siege to defend their hometowns. Khalid then bested the remaining besiegers. The Muslims then suppressed rebellions in Antioch and Qinnasrin. As northern Syria, including the area east toward the Euphrates, was conquered, Heraclius abandoned his base in Edessa for Samosata and eventually Constantinople. During his withdrawal to the capital, Heraclius disbanded the garrisons, which largely consisted of local farmers, and forts in the mountainous region between Tarsus and Alexandretta so that incoming Muslim troops encountered a deserted countryside. Abu Ubayda, while still retaining the command of Muslim troops in the north, may have played a less active role in operations there as he left to lead the siege of Jerusalem in late 636 or early 637. One reconstruction of the Islamic tradition holds that an advance force was sent against the city by Amr following the Battle of Ajnadayn. A sermon by Patriarch Sophronius of Jerusalem in Christmas 634 indicated that Jerusalem's environs, including Bethlehem, had already been in Muslim hands by then. The siege of Jerusalem was overseen by Abu Ubayda and several of the top Muslim commanders played a role. It lasted for months, as Sophronius refused to capitulate except to the caliph Umar. The latter visited the troops at their main camp at Jabiya at least once, around 637. From there, he negotiated with Jerusalem's representatives the city's capitulation. The agreement guaranteed the safety of Jerusalem's Christian inhabitants and their property and churches, and allowed them freedom of worship in return for the jizya. Byzantine troops and other residents seeking to evacuate were given safe passage until reaching their point of departure from Palestine. The historian Moshe Gil assessed that Umar adopted a lenient approach so the inhabitants could be in an economic position to subsidize the Arab tribesmen garrisoned in Palestine. An Arabic inscription dated to 652 discovered in Jerusalem mentions Abu Ubayda and Abd al-Rahman ibn Awf as witnesses in relation to Jerusalem's capitulation. The inscription was written by the then governor of Syria and katib (scribe), Mu'awiya ibn Abi Sufyan. Both Mu'awiya and Abd al-Rahman are mentioned as witnesses to the treaty by al-Tabari and Abu Ubayda is described in the Islamic sources as playing the key role in its negotiation; the historian Moshe Sharon thus proposes it was a legal document commemorating the capitulation. The coastlands of Syria, especially northern Syria and the Phoenician coast, were the last areas to submit to the Muslims. The port cities were captured by different armies and withstood sieges for longer due to the Byzantines' domination of the sea. The besieged garrisons were thus easily reinforced and resupplied, while cities captured by the Muslims were subject to Byzantine naval raids. On Palestine's coast, Yazid ibn Abi Sufyan's brother Mu'awiya led the years-long sieges of Caesarea and Asqalan, which surrendered between 639 and 641. Yazid and Mu'awiya also led the sieges and captures of Sidon, Beirut, and Byblos. A lieutenant of Abu Ubayda, Ubada ibn al-Samit, led the raids that captured Tartus and Latakia. One of the last coastal cities to fall was Tripoli, which was captured during Caliph Uthman's reign in 644. With the exception of Caesarea, the coastal cities were relatively minor operations by smaller detachments under lower-ranking commanders. Plague of Amwas In 638 and/or 639, the plague of Amwas had broken out in Syria, subsiding in October 639. The plague took a heavy toll on the Muslim army in Syria and its commanders. Abu Ubayda moved to encamp the army from its principal headquarters in Amwas in Palestine to the old Ghassanid seat of Jabiya in the Hauran highlands. Due to its healthy climate, Jabiya effectively acted as a sanatorium for plague-stricken troops and the center for the distribution of war spoils. Before reaching Jabiya, Abu Ubayda succumbed to the plague, followed soon after by his successor Mu'adh ibn Jabal, and Mu'adh's successor Yazid ibn Abi Sufyan. One of the other chief commanders in Syria, Shurahbil, also died from the plague, along with lesser commanders Suhayl ibn Amr, Suhayl's son Abu Jandal, al-Fadl ibn Abbas and al-Harith ibn Hisham. Amr ibn al-As led the surviving troops to Jabiya, and in December 639, unilaterally embarked on the conquest of Byzantine Egypt. The Islamic tradition maintains between 20,000 and 25,000 Muslim soldiers in Syria and their family members died in the plague. By 639, 4,000 soldiers were left in Jabiya out of some 24,000 in 637, though Donner notes it is unclear how many of the missing troops had died or had temporarily fled and returned to Syria eventually. The plague also caused substantial loss of life among the Christian population in Syria. During a purported visit to Syria by Umar in 639, he gave directions on the disposition of the estates of the Muslims who died in the epidemic and settled suspicious claims by some of the troops. With the loss of his top commanders in Syria, Umar split the command, appointing Yazid's brother and deputy, Mu'awiya,[e] over the ajnad ('armies'; sing. jund) of Damascus and Jordan and the veteran commander Iyad ibn Ghanm over the jund of Homs, whose jurisdiction also spanned northern Syria (Qinnasrin) and the Jazira.[f] The losses among the Muslim troops in Syria from the plague contributed to Mu'awiya's heavy military reliance on the older-established, formerly Byzantine-allied and Christian Arab tribes in Syria, particularly the Banu Kalb, who had largely stayed neutral during the fighting between the Muslims and the Byzantines. According to the historian Khalil Athamina, Medina's lack of a regular standing army, the need to redeploy fighters to other fronts, and the Byzantine threat to Muslim gains in Syria all required the establishment of a defense structure based on these older-established Arab tribes, which had historically served as confederates of Byzantium. After Medina's entreaties to the leading confederates, the Ghassanids, were rebuffed, relations were established with the Kalb, Judham and Lakhm, the former dominant in central Syria and the latter based in southern Transjordan and Palestine. These tribes probably considered the large numbers of foreign Arab tribesmen in the Muslim army, particularly those under Khalid's command, as a threat to their political and economic power.[g] Athamina attributes Umar's earlier demotion of Khalid in 636 and the redeployment of his troops soon after to the Sasanian front in Iraq as an overture to the Kalb and their tribal allies. Conquest of Byzantine Upper Mesopotamia When Iyad was appointed over Homs, Umar gave him instructions to conquer the Jazira from its Byzantine commanders because they had refused to pay the tributes promised to the Muslims in 638. By the time Iyad was given his assignment, Syria proper had been largely conquered, leaving the Byzantine garrisons in the Jazira isolated from the empire. In August 639, Iyad led a 5,000-strong army toward Raqqa (Kallinikos) in the Jazira and raided the city's environs. He encountered resistance from its defenders, prompting him to withdraw and send smaller units to raid around Raqqa, seizing captives and harvests. After five or six days of these raids, Raqqa's patrician negotiated the surrender of the city to Iyad. According to the historian Michael Meinecke, Iyad captured the city in 639 or 640. After Raqqa, Iyad proceeded toward Harran, where his progress was stalled. He diverted part of his army to Edessa, which capitulated after negotiations. Iyad then received Harran's surrender and dispatched Safwan ibn Mu'attal al-Sulami and his own kinsman Habib ibn Maslama al-Fihri to seize Samosata, which also ended in a negotiated surrender after Muslim raiding of its countryside. By 640, Iyad had successively conquered Saruj, Jisr Manbij and Tell Mawzin. Before the capture of Tell Mawzin, Iyad attempted to take Ras al-Ayn, but retreated after stiff resistance. Later, he dispatched Umayr ibn Sa'd al-Ansari to take the city. Umayr first assaulted the rural peasantry and seized cattle in the town's vicinity. The inhabitants barricaded inside the walled city and inflicted heavy losses on the Muslim forces, before capitulating. About the same time, Iyad besieged Samosata in response to a rebellion, the nature of which is not specified by al-Baladhuri, and stationed a small garrison in Edessa after the city's inhabitants violated their terms of surrender. After Samosata, al-Baladhuri, who gives a detailed but triumphalist account of the Mesopotamian campaign, maintains that Iyad subdued a string of villages "on the same terms" as Edessa's surrender. Between the end of 639 and December 640, Iyad and his lieutenants subdued, in succession, Circesium (al-Qarqisiya), Amid, Mayyafariqin, Nisibin, Tur Abdin, Mardin, Dara, Qarda and Bazabda. With the exception of Nisibin, which put up resistance, all these cities and fortresses fell to the Muslims after negotiated surrenders. In contrast to al-Baladhuri's passive account of Iyad's capture of Dara, the 10th-century historian Agapius of Hierapolis wrote that many were slain on both sides, particularly among the Muslims, and the city fell after a negotiated surrender. Iyad continued toward Arzanene, then to Bitlis and finally to Khilat; all three cities surrendered after negotiations with their patricians. Shortly after, Iyad left for Raqqa. On the way, one medieval Muslim report holds that Iyad dispatched a force to capture Sinjar, after which he settled it with Arabs. According to 9th-century scholar Ibn Sa'd, "not a foot was left of Mesopotamia unsubdued by Iyad ibn Ghanm", and Iyad "effected the conquest of Mesopotamia and its towns by capitulation, but its land by force". The tactics used in the Mesopotamian campaign were similar to those employed by the Muslims in Palestine, though in Iyad's case the contemporary accounts reveal his specific modus operandi, particularly in Raqqa. The operation to capture that city entailed positioning cavalry forces near its entrances, preventing its defenders and residents from leaving or rural refugees from entering. Concurrently, the remainder of Iyad's forces cleared the surrounding countryside of supplies and took captives. These dual tactics were employed in several other cities in the Jazira. They proved effective in gaining surrenders from targeted cities running low on supplies and whose satellite villages were trapped by hostile troops. Iyad's overall goal was to conquer the Jazira with minimal damage to ensure the flow of revenue to the caliphate. In the agreements he reached with the patricians of Raqqa, Edessa, Harran and Samosata, payments came in various forms, including cash, wheat, oil, vinegar, honey, labor services to maintain roads and bridges, and guides and intelligence for the Muslim newcomers. Iyad's settlements with Mesopotamia's cities "to a large extent left most of local society untouched". In the view of Petersen, Iyad's campaign partially diverted the Byzantines' attention away from the Muslims' central offensive against Syria's port cities and the province of Egypt, while also "demonstrating to the Armenian nobility that the Caliphate had become a viable alternative to the Persian Empire". After Iyad's death in 641, he was succeeded by Sa'id ibn Hidhyam al-Jumahi, but the latter died soon after and Umayr ibn Sa'd al-Ansari, one of Iyad's lieutenants, was appointed in his place by Umar. In late 646 or early 647, Umar's successor, Caliph Uthman, gave command over the jund of Homs–Jazira to Mu'awiya, making him governor of the entire Syrian region. Aftermath During the reign of Caliph Uthman, Constantine III decided to recapture the Levant, which had been lost to the Muslims during Umar's reign. A full-scale invasion was planned and a large force was sent to reconquer Syria. Mu'awiya ibn Abi Sufyan, the governor of Syria, called for reinforcements and Uthman ordered the governor of Kufa to send a contingent, which, together with the local garrison, defeated the Byzantine army in Northern Syria. In 645–646, Sufyan bin Mujib Al-Azdi, appointed by Mu'awiya, managed to seize Tripoli to eventually capture the last Byzantine stronghold on the Levantine coast. Uthman gave permission to Mu'awiya to build a navy. From their base in Syria, the Muslims used this fleet to capture Cyprus in 649, Crete, and Rhodes. Annual raids into western Anatolia dissuaded the Byzantines from further attempts to recapture Syria. In 654–655, Uthman ordered the preparation of an expedition to capture Constantinople, but, due to unrest in the caliphate that resulted in his assassination in 655, the expedition was delayed for decades, only to be attempted unsuccessfully under the Umayyads. The new rulers divided Syria into four districts (junds): Jund Dimashq (Damascus), Jund Hims, Jund al-Urdunn (Jordan), and Jund Filastin (Palestine) (to which a fifth, Jund Qinnasrin, was later added) and the Arab garrisons were kept apart in camps. The Muslims tolerated the Jews and Christians. The taxes instituted were the kharaj, which landowners and peasants paid according to the productivity of their fields, and the jizya, paid by non-Muslims in return for state protection and exemption from military service. The Byzantine civil service was retained until a new system could be instituted; therefore, Greek remained the administrative language in the new Muslim territories for over 50 years after the conquests[citation needed]. When the First Muslim Civil War broke out in the Islamic empire as a result of the murder of Caliph Uthman and the nomination of Ali as his successor, the Rashidun caliphs were succeeded by the Umayyad Caliphate founded by Mu'awiya, with Syria as the core powerbase for the Umayyads and Damascus as their capital for the next century to come.

Contents Microsoft acquisition hoax The Microsoft acquisition hoax is a bogus 1994 press release suggesting that the information technology company Microsoft had acquired the Roman Catholic Church. The hoax comprises part of a cycle of "Microsoft jokes" in which the Microsoft Corporation is portrayed as a wealthy but evil monopoly built on bloated or unreliable desktop software, planned obsolescence of products, corporate takeovers of once-innovative rivals, and litigiousness. While multiple books have been devoted to the subject, the jokes most commonly circulated online as Internet memes. Press release The hoax consisted of a press release, purportedly from the Associated Press, that circulated around the Internet in 1994. The press release claimed that Microsoft "will acquire the Roman Catholic Church in exchange for an unspecified number of shares of Microsoft common stock", and that the company expects "a lot of growth in the religious market in the next five to ten years... the combined resources of Microsoft and the Catholic Church will allow us to make religion easier and more fun for a broader range of people." Many of the press release's claims were unrealistic (especially for the time period), such as suggesting that Catholics would soon be able to take Holy Communion through their computer and claiming that conversion to Catholicism was an "upgrade"[clarification needed]. Despite these warning signs, several readers of the false press release contacted Microsoft to confirm the claims of the hoax, and on December 16, 1994, Microsoft formally debunked the claims. Follow-up press releases made similarly outrageous claims—for example, one false press release claimed that IBM had acquired the Episcopal Church, and another suggested that the Italian television network RAI had invested in what the release claimed to be "Microsoft Corp.'s planned on-line computer service, the Microsoft Divine Network." An Internet meme "Microsoft Acquires" spawned a series of similarly formatted mock press releases with an assortment of varying acquisition targets, including the government of the United States of America. According to the release, "United States citizens will be able to expect lower taxes, increases in government services, discounts on all Microsoft products and the immediate arrest of all executive officials of Sun Microsystems Inc. and Netscape Corp." One meta-joke claimed that Microsoft ultimately put an end to the jokes by acquiring the phrase "Microsoft Acquires". References |

Contents United States Minor Outlying Islands The United States Minor Outlying Islands is a statistical designation applying to the minor outlying islands and groups of islands that comprise eight United States insular areas and territories in the Pacific Ocean (Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll, and Wake Island) and one in the Caribbean Sea (Navassa Island). It is defined by the International Organization for Standardization's ISO 3166-1 code. The entry code is ISO 3166-2:UM. While the islands scattered across Polynesia and Micronesia are relatively small, they are strategically important and are rich in history and nature. The nearly barren Howland is famous for being the island renowned American pilot Amelia Earhart intended to land on before she vanished during her round-the-world flight in 1937. Wake, home to a now extinct flightless bird, was the site of a pitched World War II battle in 1941, and was an essential stopover for aircraft transiting the Pacific in the mid-20th century. Likewise, Midway Atoll is home to many corals and birds and was also the center of a major battle of WWII, which helped turn the tide of the Pacific War. Other islands are rich in unique biodiversity, such as Palmyra, the site of a WWII base. Johnston Atoll was a famous island for its Cold War base, when it was expanded and used to destroy chemical weapon stockpiles; it was also the site of a nuclear accident. Johnston was heavily modified with land expansion, while others are nearly untouched nature reserves. History In 1936, a colonization program began to settle Americans on Baker, Howland, and Jarvis islands. All were evacuated in 1942 due to World War II. The International Organization for Standardization (ISO) introduced the term "United States Minor Outlying Islands" in 1986. From 1974 until 1986, five of the islands (Baker Island, Howland Island, Jarvis Island, Palmyra Atoll, and Kingman Reef) were grouped under the term United States Miscellaneous Pacific Islands, with ISO 3166 code PU. The code of Midway Atoll was MI, the code of Johnston Atoll was JT, and the code of Wake Island was WK. Before 1986, Navassa Island, along with several small islands in the Caribbean Sea that are no longer under U.S. sovereignty, were grouped under the term United States Miscellaneous Caribbean Islands, with FIPS country code BQ. The populated Stewart Islands, called Sikaiana and now effectively controlled by the Solomon Islands, are not included in official lists of U.S. Minor Outlying Islands. In 1856, the Kingdom of Hawaii Privy Council and King Kamehameha IV voted to accept their voluntary cession. The Kingdom later became the Republic of Hawaii, all of which was annexed by the United States in 1898. In 1959, the resulting federal U.S. Territory of Hawaii, excluding only Palmyra Atoll and Midway Atoll, became a U.S. state. Residents of the Stewart Islands, who are Polynesian like the native Hawaiians rather than Melanesian, claimed to be citizens of the United States since the Stewart Islands were given to King Kamehameha IV in 1856 and were part of Hawaii at the time of the United States annexation in 1898. The U.S. federal and Hawaii state governments informally accept the recent claim of the Solomon Islands over the Stewart Islands, and the United States makes no official claim of sovereignty. Overview Except for Palmyra Atoll, all of these islands are unincorporated unorganized territories of the United States. Currently, none of the islands have any known permanent residents. However, military personnel, U.S. Fish and Wildlife Service personnel, and temporarily stationed scientific and research staff are posted to some islands. The 2000 census counted 315 people on Johnston Atoll and 1 person on Wake Island. The Territory of Palmyra Atoll is an incorporated territory, separated in 1959 from the rest of the former incorporated Territory of Hawaii when Hawaii became a state. There has been no recorded modern Indigenous population, except at the 1940 census. During the late 2010s, the U.S. military began reinvesting in the airfield and other assets on Wake Island. The islands are grouped for statistical convenience. They are neither administered collectively nor share a single cultural or political history beyond being uninhabited islands under the sovereignty of the United States. They are all outside the customs territory of the United States and have no customs duties. Except for Midway Atoll, the Pacific islands are surrounded by large exclusive economic zones and are within the bounds of the Pacific Islands Heritage Marine National Monument. They are collectively represented by the ISO 3166-1 alpha-2 code UM. The individual islands have ISO 3166-2 numerical codes. The Internet country code top-level domain (ccTLD) ".um" has historically been assigned to the islands; however, the .um ccTLD was retired in January 2007. Most of the U.S. Minor Outlying Islands islands are closed to the public. Visitors to islands such as Jarvis Island need a permit. Palmyra Atoll is open to the public, but there is no easy way to reach it. Islands and atolls Transportation Airports in the United States Minor Outlying Islands provide critical emergency landing points across the vast Pacific Ocean for all aircraft types, allow for important military presence in key strategic zones, and have limited scheduled commercial services. The following is a list of island airports with ICAO (IATA) codes: Other airports include: Three of the islands are listed with ports in the World Port Index, with World Port Number: Baker Island, Howland Island, and Jarvis Island each have small boat landing places. Kingman Reef and Navassa Island only have offshore anchorages. Flora and fauna See also References External links |

Contents Fanny Brate Fanny Ingeborg Matilda Brate (née Ekbom; 26 February 1861 – 22 April 1940) was a Swedish painter. She specialized in genre scenes, featuring families, which are often cited as the inspiration for similar works by Carl Larsson. Biography Fanny Brate was the daughter of Johan Frans Gustaf Oskar Ekbom (1832-1894), a clerk in the household of Prince Oscar, Duke of Östergötland (later, King Oscar II), and she was born in the Arvfurstens palats. From 1868 to 1877, she studied at a girls' school, followed by drawing lessons at the Arts and Crafts School. She became a full-time student there from 1878 to 1879. That year, she began taking classes from August Malmström at the Royal Swedish Academy of Fine Arts. In 1885, she received a Royal Medal [sv] for a painting of herself surrounded by school children. In 1887, with the help of a travel scholarship from the Royal Academy, she attended classes at the Académie Colarossi in Paris. Later that year, she married the runologist, Erik Brate. They had four daughters. Torun [sv], their second, also became a painter. She continued to make study trips throughout Western Europe, including a visit to the Exposition Universelle (1889). By the turn of the century, she had adopted Impressionist styles and joined the Skagen Painters. Many of her works depicted her own children. The process of raising them also inspired her to illustrate children's books, such as Mormors eventyr (Grandma's Tales), and take part in the ongoing debate about education. In 1891, she became a member of the Svenska konstnärernas förening [sv] (the Swedish Artists' Association). The Nationalmuseum held a memorial exhibition of her collected works in 1943. Her works may also be seen at the Nordiska museet and the Göteborgs konstmuseum Selected paintings References Further reading External links |

Contents Howard Lincoln Howard Charles Lincoln (born February 14, 1940) is an American lawyer and businessman, known primarily for being the former chairman of Nintendo of America and the former chairman and chief executive officer (CEO) of the Seattle Mariners baseball team, representing absentee majority owner Hiroshi Yamauchi until Yamauchi died on September 19, 2013. Early life Born in Oakland, California, Lincoln was an active Boy Scout. As a thirteen-year-old boy, he posed for the famous Norman Rockwell painting The Scoutmaster, which was published in a calendar in 1956. In the painting, young Lincoln is on the immediate right of the campfire. Lincoln eventually attained the rank of Eagle Scout and received a Distinguished Eagle Scout Award. Lincoln matriculated in 1957 at the University of California, Berkeley, where he earned his BA in political science in 1962 and his Juris Doctor degree from University of California, Berkeley School of Law in 1965. From 1966 to 1970, he served as a lieutenant within the United States Navy Judge Advocate General's Corps. He then worked in private practice as an attorney in Seattle, Washington. Nintendo Lincoln did legal work in 1981 for Nintendo, culminating in the legal case Universal City Studios, Inc. v. Nintendo Co., Ltd., in which Universal City Studios had sued Nintendo claiming that the video game Donkey Kong infringed upon Universal City Studio's rights to King Kong. Lincoln hired John Kirby to represent Nintendo in the courtroom. Nintendo won the case, as well as successive court appeals. Lincoln met Yamauchi in 1982 and joined Nintendo in 1983, as its Senior Vice President and General Counsel. He and Minoru Arakawa were instrumental in rebuilding the North American video game industry (after the crash of 1983) with their highly successful marketing of the Nintendo Entertainment System. In 1994, he was appointed its chairman. As Vice President of Nintendo, Lincoln was involved in litigation with Tengen, a subsidiary of Atari Games, about the rights to Tetris, and defended Nintendo's use of the 10NES lock-out chip. He represented the company in the 1993 United States Senate hearings on video games, during which he promised Joe Lieberman and Herb Kohl he would not release Night Trap on a Nintendo console because it was considered inappropriate for children. Lincoln announced his retirement from Nintendo in 1999 and departed the company in 2000. Seattle Mariners In September 1999, Lincoln became CEO of the Seattle Mariners, serving as the point man for majority investor Hiroshi Yamauchi when it came to making decisions (up until 2008, Lincoln noted that Yamauchi only pushed heavily for the team to pursue three players: Kazuhiro Sasaki, Ichiro Suzuki and Kenji Johjima); it was Lincoln that hired Pat Gillick to serve as general manager for the 2000 season. Lincoln's tenure as CEO of the Seattle Mariners saw both success and controversy. Lincoln was considered instrumental, along with former senator Slade Gorton, in preserving the team's location in Seattle and negotiating with the city for a new stadium, Safeco Field. His stewardship has seen the team's first post-season appearances, in 1995, 1997, 2000, and 2001, as well as the aggressive expansion of the Mariners into the Japanese market, most noticeably through the acquisition of Japanese superstar Ichiro Suzuki. Lou Piniella left after the 2002 season and Pat Gillick left the following year. Pinella once described Lincoln and Gillick prior to his departure: "I like Howard personally. I enjoyed working with him. He's a bright guy, a charming guy. But I'll tell you this -- he's bottom line. Howard likes total, total control. Pat wants to win. Howard just doesn't know how." Lincoln disagreed with that remark, stating that he gave the benefit of the doubt to those he had serve as general manager. Lincoln replaced Pinella with Bob Melvin and Gillick with Bill Bavasi, with the latter being considered by Lincoln as a regret. In 2002, the first season without playoff baseball for the Mariners in years, he was quoted as saying the following about the goal set out for the team when it came to acquisitions in or out of season: "You can go to the Series two ways; first, go for it regardless of the financial risk or consequences, the way Cleveland or Florida has; or go for it with a competitive team that plays for championships on a continual basis. The objective of the Seattle Mariners is not to go to the World Series regardless of the financial consequences, that is irresponsible." (this clarification arose after he had been quoted as saying the goal of the team was not to win a World Series but to be competitive every year). From 2003 to 2016, the Mariners went through nine different managers, with none of them reaching the playoffs under Lincoln (who was reported as having kept a notebook of the insults leveled at him up to 2004) as CEO. In April 2016, Lincoln retired as CEO, concurrent with Nintendo selling most of its stake in the team. Philanthropy In addition to Lincoln's business achievements, he is an active philanthropist. He has served as campaign chair for United Way of King County and the Chief Seattle Council of the Boy Scouts of America. He is also a trustee of Western Washington University.

[SOURCE: https://en.wikipedia.org/wiki/Sector_(instrument)] | [TOKENS: 5786] |
Contents Sector (instrument) The sector, also known as a sector rule, proportional compass, or military compass, is a major calculating instrument that was in use from the end of the sixteenth century until the nineteenth century. It is an instrument consisting of two rulers of equal length joined by a hinge. A number of scales are inscribed upon the instrument which facilitate various mathematical calculations. It is used for solving problems in proportion, multiplication and division, geometry, and trigonometry, and for computing various mathematical functions, such as square roots and cube roots. Its several scales permitted easy and direct solutions of problems in gunnery, surveying and navigation. The sector derives its name from the fourth proposition of the sixth book of Euclid, where it is demonstrated that similar triangles have their like sides proportional. Some sectors also incorporated a quadrant, and sometimes a clamp at the end of one leg which allowed the device to be used as a gunner's quadrant. History The sector was invented, essentially simultaneously and independently, by a number of different people prior to the start of the 17th century. Fabrizio Mordente (1532 – ca 1608) was an Italian mathematician who is best known for his invention of the "proportional eight-pointed compass" which has two arms with cursors that allow the solution of problems in measuring the circumference, area and angles of a circle. In 1567 he published a single sheet treatise in Venice showing illustrations of his device. In 1585 Giordano Bruno used Mordente's compass to refute Aristotle's hypothesis on the incommensurability of infinitesimals, thus confirming the existence of the "minimum" which laid the basis of his own atomic theory. Guidobaldo del Monte developed a "polymetric compass" c. 1670, including a scale for constructing regular polygons. The Italian astronomer Galileo Galilei added further scales in the 1590s, and published a book on the subject in 1606. Galileo's sector was first designed for military applications, but evolved into a general purpose calculating tool. The two earliest known sectors in England were made by Robert Beckit and Charles Whitwell, respectively, both dated 1597. These have a strong resemblance to the description of the device given by English mathematician Thomas Hood's 1598 book. The sector Hood described was intended for use as a surveying instrument and included sights and a mounting socket for attaching the instrument to a pole or post, as well as an arc scale and an additional sliding leg. In the 1600s, the British mathematician Edmund Gunter dispensed with accessories but added additional scales, including a meridian line with divisions proportional to the spacing of latitudes along a meridian on the Mercator projection, privately distributing a Latin manuscript explaining its construction and use. Gunter published this in English as De Sectore et Radio in 1623. Galileo's sector Galileo first developed his sector in the early 1590s as a tool for artillerymen. By 1597 it had evolved into an instrument that had much broader utility. It could be used, for example, to calculate the area of any plane figure constructed from a combination of straight lines and semi-circles. Galileo was determined to improve his sector so that it could be used to calculate the area of any shape discussed in Euclid's Elements. To do this, he needed to add the capability to calculate the area of circular segments. It took him more than a year to solve this problem. The instrument we know today as Galileo's sector is the version with this added capability that he began to produce in 1599 with the help of the instrument maker Marc'Antonio Mazzoleni. Galileo provided Mazzoleni and his family with room and board, and paid him two-thirds of the 35 lire selling price; Galileo would charge 120 lire for a course teaching the use of the instrument, about half the annual wage of a skilled craftsmen. Most of his customers were wealthy noblemen, including Archduke Ferdinand, to whom Galileo sold a sector made of silver. More than a hundred were made in all, but only three are known to exist today: one in the Putnam Gallery at Harvard University, one in the Museum of Decorative Art in Milan's Castello Sforzesco, and one in the Galileo Museum in Florence. Galileo described how to perform 32 different calculations with the sector in his 1606 manual. In the introduction, Galileo wrote that his intention in producing the sector was to enable people who had not studied mathematics to perform complex calculations without having to know the mathematical details involved. The sector was used in combination with a divider, also called a compass. Each arm of the sector was marked with four lines on the front, and three on the back, and the pivot had a dimple that would accept the point of a divider. The lines and scales on each arm were identical, and arranged in the same order as you moved from the inner edge to the outer edge, thus forming seven pairs of lines. All the calculations could be performed with some combination of five very simple steps: measuring some length, separation or object width with the divider; opening the arms of the sector and setting the crosswise distance between two corresponding points on a pair of lines to the divider separation; measuring the crosswise distance between two corresponding points on a pair of lines once the sector had been set to some separation; reading a value from one of the scales at a point where the crosswise distances matches a divider separation; and reading a value off a scale where the distance from the pivot matches a divider. Galileo did not describe how the scales were constructed, he considered that a trade secret, but the details can be inferred. Scale markings were placed with an accuracy of about 1%. The innermost scales of the instrument are called the arithmetic lines from their division in arithmetic progression, that is, a linear scale. The sector in the Galileo Museum is marked from 16 to 260. If we call the length from the pivot A , {\displaystyle A,} then given two marks with values n 1 {\displaystyle n_{1}} and n 2 , {\displaystyle n_{2},} the ratios of their lengths are in proportion to the ratios of the numbers. In modern notation: Galileo describes how to use these scales to divide a line into a number of equal parts, how to measure any fraction of a line, how to produce a scaled version of a figure or map, how to solve Euclid's Golden Rule (also called the Rule of Three), how to convert a value in one currency into the value in another currency, and how to calculate the compounded value of an investment. As an example, the procedure for calculating the compounded value of an investment is as follows. If the initial investment is P0, set the divider to the distance from the pivot to the point marked at P0 on the arithmetic lines. Open the instrument and set the crosswise distance at the point 100–100 on the arithmetic lines to the distance just measured to P0. If the interest rate for the period is say 6%, then set the divider to the crosswise distance at 106-106. Place the divider at the pivot, and see where the other end falls on the arithmetic lines. This is the value of the investment at the end of the first period. Now set the crosswise distance at 100-100 again to the current divider separation and repeat the procedure for as many periods as needed. The next set of lines are called the geometric lines, which have a scale numbered from 1 to 50, with lengths proportional to the square root, called geometric because they are used for finding the geometric mean and working with areas of plane figures. If we call the length from the pivot G , {\displaystyle G,} then: Galileo describes how to use these lines to scale a figure such that the new figure has a given area ratio to the original, how to measure the area ratio of two similar figures, how to combine a set of similar figures into another similar figure such that the resulting figure has the combined area of the set, how to construct a similar figure that has area equal to the difference in area of two other similar figures, how to find the square root of a number, how to arrange N soldiers into a grid where the ratio of rows to columns is some specified value, and how to find the geometric mean of two numbers. As an example, the procedure for producing a similar figure that has the combined area of a set of similar figures, is as follows: Choose a side in the largest figure and measure its length with a divider. Open the sector and set the crosswise distance at some intermediate value on the geometric lines to the divider separation, any number will do, say 20. Then measure the length of the corresponding side in each of the other figures, and read the Geometric Line scale value where the crosswise distance matches these lengths. Add together all the scale readings, including the 20 we originally set. At the combined value on the geometric lines, measure the crosswise distance. This will be the length of the side of the figure that has the combined area of the set. You can then use the arithmetic scale to scale all the other side lengths in the largest figure to match. This procedure will work for any closed figure made from straight lines. The procedure for calculating a square root varies depending on the size of the radicand. For a "medium" number ("in the region of 5,000"), start by measuring the distance from the pivot to the point marked 40 on the arithmetic lines, and setting the crosswise distance of the sector at 16–16 on the geometric lines to this distance. Next take your number and divide by 100, rounding to the nearest integer. So for example 8679 becomes 87. If this number is greater than 50 (the largest value on the geometric lines scale) then it must be reduced, in this example perhaps divided by 3 to make 29. Next measure the crosswise distance on the geometric lines at 29, this distance on the arithmetic lines represents 2900 . {\displaystyle {\sqrt {2900}}.} Because our number was reduced to fit on the sector, we must scale the length up by 3 . {\displaystyle {\sqrt {3}}.} We can choose any convenient value, e.g. 10, setting the sector crosswise distance at 10 to the divider separation, and then measure the crosswise distance at 30 on the geometric lines, then place the divider against the arithmetic lines to measure 8700 , {\displaystyle {\sqrt {8700}},} which is close enough to 8679 {\displaystyle {\sqrt {8679}}} The procedure for calculating the square root of a “small” number, a number “around 100”, is simpler: we don't bother dividing by 100 at the beginning but otherwise perform the same procedure. At the end, divide the resulting square root estimate by 10. For "large" numbers ("around 50,000"), set the sector crosswise at 10–10 on the geometric lines to the distance from the pivot to the point at 100 on the arithmetic lines. Divide the number by 1000 and round to the nearest integer. Then follow a similar procedure as before. Galileo provides no further guidance, or refinement. Knowing which procedure to use for a given number requires some thought, and an appreciation for the propagation of uncertainty. The stereometric lines are so called because they relate to stereometry, the geometry of three-dimensional objects. The scale is marked to 148, and the distance from the pivot is proportional to the cube root. If we call the length S , {\displaystyle S,} then These lines operate in an analogous way to the geometric lines, except that they deal with volumes instead of areas. Galileo describes how to use these lines to find the corresponding side length in a similar solid where the solid has a given volume ratio to the original, how to determine the volume ratio of two similar solids given the lengths of a pair of corresponding sides, how to find the side lengths of a similar solid that has the combined volume of a set of other similar solids, how to find the cube root of a number, how to find the two values intermediate between two numbers p {\displaystyle p} and q {\displaystyle q} such that n 1 = r p {\displaystyle n_{1}=rp} , n 2 = r 2 p {\displaystyle n_{2}=r^{2}p} and q = r 3 p {\displaystyle q=r^{3}p} for a given scaling factor r {\displaystyle r} , and how to find the side of a cube that has the same volume as a rectangular cuboid (square-cornered box). To cube a rectangular cuboid of sides a {\displaystyle a} , b , {\displaystyle b,} and c {\displaystyle c} amounts to computing s = a b c 3 . {\displaystyle s={\sqrt[{3}]{abc}}.} Galileo's method is to first use the geometric lines to find the geometric mean of two of the sides, g = a b . {\displaystyle g={\sqrt {ab}}.} He then measures the distance along the arithmetic lines to the point marked g {\displaystyle g} using a divider, and then sets the sector crosswise to this distance at the point marked g {\displaystyle g} on the stereometric lines, calibrating the sector so that the distance from the pivot to the point g {\displaystyle g} on the stereometric lines represents a b 3 , {\displaystyle {\sqrt[{3}]{ab}},} the side of a cube with the volume of a cuboid with sides a , {\displaystyle a,} b , {\displaystyle b,} and 1. {\displaystyle 1.} He then measures the distance from the pivot to the point marked c {\displaystyle c} on the arithmetic lines, and sees at what value on the stereometric lines this distance fits crosswise, thus multiplying the previous result by c 3 , {\displaystyle {\sqrt[{3}]{c}},} resulting in a b c 3 {\displaystyle {\sqrt[{3}]{abc}}} as desired. The procedure for calculating cube roots is like that used for square roots, except that it only works for values of 1,000 or more. For “medium” numbers we set the sector crosswise at 64–64 on the stereometric lines to the distance from the pivot to the point marked 40 on the arithmetic lines. We then drop the last three digits from our number, and if the number we dropped was more than 500, we add one to the remainder. We measure the crosswise distance on the stereometric lines at the remainder value, and place this against the arithmetic lines to find the cube root. The largest number that can be handled without rescaling here is 148,000. For “large” numbers we set the sector crosswise at 100–100 on the stereometric lines to the distance from the pivot to the point 100 on the arithmetic lines, and instead of dropping three digits, we drop four. This can handle numbers from 10,000 up to 1,480,000 without rescaling. For practical use, you should use the medium number procedure for all values up to 148,000 that are not within about 2% of a multiple of 10,000. The metallic lines, the outermost pair on the front face, are marked with the symbols "ORO" (for oro, gold), PIO (for piombo, lead), "AR" (for argento, silver), "RA" (for rame, copper), "FE" (for ferro, iron), "ST" (for stagno, tin), "MA" (for marmo, marble), and "PIE" (for pietra, stone). These symbols are arranged by decreasing specific weights or densities, with distance proportional to the inverse cube root. Given two materials of density ρ 1 {\displaystyle \rho _{1}} and ρ 2 , {\displaystyle \rho _{2},} if we call the length from the pivot M , {\displaystyle M,} The ratio of lengths on this scale is proportional to the ratio of diameters of two balls of the same weight but different materials. These lines were of interest to artillerymen to solve the problem of “making the caliber”, that is how to figure out the correct powder charge to use for a cannonball of some size and material, when the correct charge is known for a cannonball of a different size and material. To do that, you would measure the diameter of the cannonball with the known charge and set the sector crosswise at this cannonball's material mark on the metallic lines to that diameter. The crosswise distance at the second cannonball's material type gives you the diameter of a cannonball in this material that is the same weight as the first ball. We need to scale this length down stereometrically to the given diameter of the second ball to get the correct charge, so we set the crosswise distance on the stereometric lines at 100–100 to the crosswise distance we just measured from the metallic lines, and then see where the crosswise distance on the stereometric lines matches the actual diameter of the second ball. The charge required is then in the ratio of this scale reading to 100 compared to the ball with known charge. You could then use the arithmetic lines to scale the charge weight in this ratio. The polygraphic lines, innermost scale on the back of the instrument, is labelled from 3 to 15, and the distance from the pivot is inversely proportional to the side length of a regular polygon of n {\displaystyle n} sides inscribed in a given circle, or directly proportional to the circumradius of a regular polygon of n {\displaystyle n} sides of a given length. If P {\displaystyle P} is the length on the polygraphic scale and crd {\displaystyle \operatorname {crd} } represents the trigonometric chord length of a circular arc measured in degrees, then Using functional notation in terms of the modern sine function, where R {\displaystyle R} is the circumradius for a hexagon, P ( 6 ) = R . {\displaystyle P(6)=R.} These lines can be used to aid in the construction of any regular polygon from the 3-sided equilateral triangle to the 15-sided pentadecagon. Galileo describes how to use these lines to find the radius of an enclosing circle for a polygon of n sides of a given length or in the other direction how to find the length of a chord that divides the circumference of a circle into n {\displaystyle n} parts. The procedure for finding the radius of the enclosing circle is as follows: Open the sector and set the crosswise distance at the point 6–6 on the polygraphic lines to the desired side length. The distance measured crosswise at n {\displaystyle n} on the polygraphic lines is the radius of the enclosing circle. The tetragonic lines are marked from 13 down to 3 as you move away from the pivot, and the distance from the pivot can be inferred to be L ( n ) = L t n 3 tan 180 n {\displaystyle L(n)=L_{t}{\sqrt {\frac {n}{{\sqrt {3}}\tan {\frac {180}{n}}}}}} , where L t {\displaystyle L_{t}} is the distance from the pivot to the point marked 3. There is a circle on the scale that lies nearly midway between 6 and 7. The name comes from tetragon (quadrilateral), as the main purpose of these lines is the quadrature of regular polygons, that is, finding the side of a square whose area is the same as the given regular polygon. They can also be used to square the circle. The area of a regular polygon with n {\displaystyle n} sides is A ( n ) = L 2 n 4 tan 180 n {\displaystyle A(n)=L^{2}{\frac {n}{4\tan {\frac {180}{n}}}}} , where L {\displaystyle L} is the side length of the polygon. The radius of the circle with equal area is r = L n 4 π tan 180 n {\displaystyle r=L{\frac {n}{4\pi \tan {\frac {180}{n}}}}} . The value of n {\displaystyle n} at which the radius of the circle is the same as the side length of the polygon, is n = 6.5437 {\displaystyle n=6.5437} . There is, of course, no such polygon, but this gives us a reference point on the Tetragonic Lines, the indicated circle, where it is easy to read off crosswise the radius of the circle that is equal in area to the polygon with n {\displaystyle n} sides if we set the sector at n {\displaystyle n} on the Tetragonic Lines crosswise to the polygon side length. Squaring the circle is then just using n = 4 {\displaystyle n=4} . To square the polygon, all we do is set the sector crosswise at n {\displaystyle n} to the side length, and measure crosswise at n = 4 {\displaystyle n=4} . It is just as easy to find the required side lengths for any two polygons of equal area with different number of sides. The outermost set of lines on the back have a double scale, an outer and an inner scale. The outer scale is linear and runs from 18 down to 0 as you move away from the pivot, and the zero point is marked with a ⌓, the symbol for a circular segment. This zero point is about 70% of the way out along the arm. The inner scale is also described to run from 18 down to 0, but the sector in the Galileo Museum is only marked from 17. The zero point on the inner scale lies further out on the arm, at a distance of π / 2 L a {\textstyle {\sqrt {\pi /2}}L_{a}} where L a {\displaystyle L_{a}} is the distance from the pivot to the zero on the outer scale, and the zero is marked with a small square. The outer scale zero lies close to the point marked 6 on the inner scale. The inner scale at first glance also appears linear, but its point spacings are actually determined by a fairly complex formula which we have to infer as Galileo does not describe how this scale was constructed. The name of these lines derives from the fact that they were added by Galileo to an earlier version of his sector. These lines are used for squaring circular segments, that is finding the side length of a square that is equal in area to a circular segment with a given chord length and height, where the segment is at most a semicircle. The procedure for square a circular segment is as follows. Measure the half-length of the chord, c {\displaystyle c} . At the chord midpoint, measure the length of the line perpendicular to the chord to where it intersects the circle, the height h {\displaystyle h} . Set the sector crosswise on the added lines at the zero of the outer scale to the half-chord length, c {\displaystyle c} . Find the point on the outer scale, n {\displaystyle n} , where the crosswise distance is h {\displaystyle h} ; h {\displaystyle h} must be less than or equal to c {\displaystyle c} . Move to the point on the inner scale that is also marked n {\displaystyle n} . The crosswise distance between the points n-n on the inner scale is the side length of the square equal in area to the circular segment. To see how this works, we start by noting (as can be seen in the figure in circular segment), that the area of the segment is the difference between the area of the pie slice defined by where the chord cuts the circle, and the triangle formed by the chord and the two radii that touch the ends of the chord. The base of the triangle has length 2 c {\displaystyle 2c} , and the height of the triangle is r − h {\displaystyle r-h} , so the area of the triangle is A t = c ( r − h ) {\displaystyle A_{t}=c(r-h)} . Using Pythogras' theorem, we can show that r = ( c 2 + h 2 ) / 2 h {\displaystyle r=(c^{2}+h^{2})/2h} . The area of the pie slice is the fraction of the area of the circle covered by the angle θ {\displaystyle \theta } . For θ {\displaystyle \theta } in radians, this area is A p i e = θ / 2 r 2 = r 2 arcsin ( c / r ) {\displaystyle A_{pie}=\theta /2r^{2}=r^{2}\arcsin(c/r)} , where arcsin {\displaystyle \arcsin } is the inverse sine function. If we define x = h / c {\displaystyle x=h/c} , and z = ( 1 + x 2 ) / 2 x {\displaystyle z=(1+x^{2})/2x} , then we can write the area of the segment as A s e g = c 2 ( z 2 arcsin 1 / z − z + x ) {\displaystyle A_{seg}=c^{2}(z^{2}\arcsin 1/z-z+x)} . The distance from the pivot to the point marked n {\displaystyle n} on the outer scale is L o u t e r ( n ) = L a ( 1 − n / 20 ) {\displaystyle L_{outer}(n)=L_{a}(1-n/20)} where L a {\displaystyle L_{a}} is the distance from the pivot to the zero point on the outer scale. When we set the sector crosswise to c {\displaystyle c} at the zero point and find the point on the outer scale where the crosswise distance is h {\displaystyle h} , we set up a pair of similar triangles that share the angle made by the arms of the sector at the pivot, so that h / c = 1 − n / 20 {\displaystyle h/c=1-n/20} . If we set the distance of the point n {\displaystyle n} from the pivot on the inner scale to L i n n e r ( n ) = L a z 2 arcsin 1 / z − z + x {\textstyle L_{inner}(n)=L_{a}{\sqrt {z^{2}\arcsin 1/z-z+x}}} , with x = 1 − n / 20 {\displaystyle x=1-n/20} , and z {\displaystyle z} defined as before, then the crosswise distance measured at n {\displaystyle n} on the inner scale will be the side length of the square with area equal to that of the segment. Other uses The sector came with a plumb bob and a detachable quadrant which, when in place, would lock the arms at 90° to each other. The sector could then be used for sighting and distance measurements using triangulation, with applications in surveying and ballistics. The sector could also be used to easily determine the elevation of a cannon by inserting one arm into the barrel and reading the elevation from the location of the plumb bob.

Contents Burgenland Burgenland (Austrian German pronunciation: [ˈbʊrɡn̩land] ⓘ; Hungarian: Őrvidék; Croatian: Gradišće; Austro-Bavarian: Burgnland; Slovene: Gradiščanska; Slovak: Hradsko) is the easternmost and least populous state of Austria. It consists of two statutory cities and seven rural districts, with a total of 171 municipalities. It is 166 km (103 mi) long from north to south but much narrower from west to east (5 km or 3 mi wide at Sieggraben). The population of Burgenland as of 1 January 2025 is 301,790. Burgenland's capital is Eisenstadt. The area once belonged to the Kingdom of Hungary, which was obliged under the Treaty of Trianon in 1920 to cede what was then German West Hungary (Deutsch-Westungarn) to the newly formed Republic of Austria. In 1921, the annexation of Burgenland was completed; the newly acquired territory was given the legally binding name Burgenland by the Federal Constitutional Act of 25 January 1921. Burgenland borders the city of Bratislava to the north, the Hungarian counties of Győr-Moson-Sopron and Vas to the east, the two municipalities of Kuzma and Rogašovci (Slovenia) for a few kilometers to the south, and the Austrian federal states of Styria and Lower Austria to the west. The proportion of permanent settlement area within the state territory amounts to 62.76%, the second-highest value among Austria’s nine territorial federal states after Vienna. Burgenland is characterized by Lake Neusiedl in the north and the foothills of the Alps in the hilly south. It is elongated in shape and narrows at Sieggraben in the Ödenburg Mountains to a width of 4 km. The region is part of the Centrope Project. History The territory of present-day Burgenland was successively part of the Roman Empire, the Hun Empire, the Kingdom of the Ostrogoths, the Italian Kingdom of Odoacer, the Kingdom of the Lombards, the Avar Khaganate, the Frankish Empire, Dominion Aba belonging to the Aba (family); Aba – Koszegi, the Kingdom of Hungary, the Habsburg monarchy, the Austrian Empire, Austria-Hungary, and lastly Austria. Burgenland is the only Austrian province that has never been part of the Archduchy of Austria, Holy Roman Empire, German Confederation nor Austria-Hungary's Cisleithania. From the 4th century BC, the area was dominated by Celts and in the 1st century AD it became part of the Roman Empire. During Roman administration, it was part of the province of Pannonia, and later part of the provinces of Pannonia Superior (in the 2nd century) and Pannonia Prima (in the 3rd century). During the late Roman Empire, Pannonia Prima province was part of larger administrative units, such are Diocese of Pannonia, Praetorian prefecture of Illyricum and Praetorian prefecture of Italy. The first Germanic people to settle in this region were the Ostrogoths, who came to Pannonia in AD 380. The Ostrogoths became allies of Rome and were allowed to settle in Pannonia, being tasked to defend the Roman borders. In the 5th century, the area was conquered by the Huns, but after their defeat, an independent Kingdom of the Ostrogoths in Pannonia was formed. The territory of present-day Burgenland became part of the Italian Kingdom of Odoacer, but at the end of the 5th century the Ostrogothic king Theodoric conquered this kingdom and restored Ostrogothic administration in western Pannonia. In the 6th century, the territory was included in another Germanic state, the Kingdom of the Lombards. However, the Lombards subsequently left towards Italy and the area came under the control of the Avars. For a brief period in the 7th century, the area became part of the Slavic State of Samo, however it subsequently came back under Avar control. After the Avar defeat at the end of the 8th century, the area became part of the Frankish Empire. After the Battle of Lechfeld (or Augsburg) in 955, new Germanic settlers came to the area. In 1043, Henry III and King Samuel Aba of Hungary signed a peace treaty. On 20 September 1058, Agnes of Poitou and Andrew I of Hungary met to negotiate the border. The area of Burgenland remained the western frontier of the medieval Kingdom of Hungary until the 16th century. The majority of the population was Germanic, except for the Hungarian border guards of the frontier March (Gyepű). Germanic immigration from neighbouring Austria was also continuous in the Middle Ages. In 1440 the territory of present-day Burgenland was controlled by the Habsburgs of Austria, and in 1463 the northern part of it (with the town of Kőszeg) became a mortgage-territory according to the peace treaty of Wiener Neustadt. In 1477 King Matthias Corvinus of Hungary had retaken the area, but in 1491 it was mortgaged again by King Vladislaus II of Bohemia and Hungary to Emperor Maximilian I. In 1647 Emperor Ferdinand II returned it to the Kingdom of Hungary (which itself was a Habsburg possession in this time). In the 16th century, the medieval Kingdom of Hungary lost its independence and its northwestern part that was not conquered by the Ottoman Empire was included in the Habsburg Empire. This Habsburg possession was known as Royal Hungary and it included territory of present-day Burgenland and western Hungary. Royal Hungary still had counties. What is today Burgenland was in those times the Moson, Sopron and Vas counties of Hungary. In the 16th and 17th centuries German Protestant refugees arrived in Western Royal Hungary to shelter from the religious wars of the Holy Roman Empire, particularly from the suppression of the Reformation in Austrian territories, then ruled by the staunchly Roman Catholic Habsburgs. After the Habsburg military victory against the Ottomans at the end of the 17th century, the Habsburg Kingdom of Hungary was enlarged to include much of the territory of the former medieval Kingdom of Hungary. In the 17th and 18th centuries the region of Western Hungary was dominated by the wealthy Catholic landowning families, for example the Esterházys and Batthyánys. In 1867, the Habsburg Empire was transformed into the dual monarchy of Austria-Hungary. According to the 1910 census 291,800 people lived on the territory of present-day Burgenland. Among them 217,072 were German-speaking (74%), 43,633 Croatian-speaking (15%) and 26,225 (9%) Hungarian-speaking. Roma people were counted according to their native language. In December 1918, the Republic of Heinzenland was declared by Austrian politician Hans Suchard [de] with the goal of the territory being annexed by Austria. However, it was taken over within two days by Hungary. From March to August 1919, Burgenland was part of the Hungarian Soviet Republic. The area had also been discussed as the site of a Czech Corridor to Yugoslavia. The decision on "German West Hungary" (Deutsch-Westungarn) was fixed in the treaties of Saint Germain and Trianon. Despite diplomatic efforts by Hungary, the victorious parties of World War I set the date of Burgenland's official unification with Austria for 28 August 1921. However, on that day sharpshooters with the support of Hungary prevented the establishment of Austrian police control and customs. Lieutenant Colonel Pál Prónay and his men, the Rongyos Gárda, defended western Hungary from occupation by Austrian officials and forces of the Austrian Gendarmerie. Prónay had help from Hungarians and Croatians who did not want to live under Austrian rule, leading to the Uprising in West Hungary in 1921. Prónay occupied the whole area and created the state of Lajtabánság. With the help of Italian diplomatic mediation in the Venice Protocol, the crisis was resolved in the autumn of 1921, when Hungary committed to disarm the sharpshooters by 6 November 1921. This was in exchange for a plebiscite on the unification of certain territories, including Ödenburg (Sopron), the designated capital of Burgenland, and eight surrounding villages. The vote took place from 14 to 16 December, and resulted in a clear (but doubted by Austria)[citation needed] vote of the people who inhabited the Sopron district to be part of Hungary. Consequently, the territory was incorporated into Austria, except for the Sopron district which was united with Hungary. Further border adjustments were made in 1922 by the League of Nations border committee. After their decision was approved on 17 September, 10 Settlements were returned to Hungary. That included 8 settlements in the Pinka valley: Kisnarda, Nagynarda, Felsőcsatár, Alsócsatár, Németkeresztes, Magyarkeresztes, Horvátlövő and Pornóapáti, as well as Rendek (Liebing) and Rőtfalva (Rattersdorf) north of Kőszeg. The last two were handed back to Austria in a swap agreement on 22 November in exchange for Szentpéterfa and Ólmod. In contrast to all the other present Austrian states, which had been part of Cisleithania, Burgenland did not constitute a specific Kronland, and when it was formed it did not have its own regional political and administrative institutions such as a Landtag (representative assembly) and Statthalter (Imperial governor). On 18 July 1922, the first elections for the parliament of Burgenland took place. Various interim arrangements were required due to the changeover from Hungarian to Austrian jurisdiction. The parliament decided in 1925 on Eisenstadt as the capital of Burgenland, and moved from the various provisional estates throughout the country to the newly built Landhaus in 1929. The first Austrian census in 1923 registered 285,600 people in Burgenland. The ethnic composition of the province had changed slightly: the percentage of German speakers increased compared to 1910 (227,869 people, 80%) while the percentage of Hungarian speakers rapidly declined (14,931 people, 5%). This was due mainly to the emigration of the Hungarian civil servants and intellectuals after the territory was ceded to Austria. In 1923, emigration to the United States of America, which started in the late 19th century, reached its climax; in some places up to a quarter of the population went overseas. After the Nazi German Anschluss of Austria, the administrative unit of Burgenland was dissolved. Northern and central Burgenland joined the district of Niederdonau (Lower Danube) while southern Burgenland joined Styria.[citation needed] The Jews of Burgenland were forced to emigrate in the immediate aftermath of the Anschluss. The policy of Germanization also affected other minorities, especially Burgenland Croats and Hungarians. Minority schools were closed and the use of their native language discouraged. In 1944, Nazi Germany began to build the Südostwall (South-east wall) with the help of mostly Jewish forced labor and collaborating inhabitants. Soviet troops crossed the Hungarian–Austrian border during the Vienna offensive and were only somewhat delayed by the unfinished fortifications. In the last days of the Nazi regime many executions and death marches of Jewish forced laborers took place. On 1 October 1945, Burgenland was reestablished as a state with Soviet support. as part of their occupation zone. Under Soviet occupation, people in Burgenland had to endure a period of serious mistreatment and an extremely slow economic progress, the latter induced by the presence of Soviet troops which discouraged investment.[citation needed] The Soviet occupation ended with the signing of the Austrian Independence Treaty of Vienna in 1955 by the Occupying Forces. The brutally crushed Hungarian Revolution on 23 October 1956 resulted in a wave of Hungarian refugees on the Hungarian–Austrian border, especially at the Andau Bridge (Brücke von Andau). They were received by the inhabitants of Burgenland with overwhelming hospitality. In 1957, the construction of the Iron Curtain resulted in a complete sealing off of the area under Soviet influence from the rest of the world, turning the Hungarian-Austrian border next to Burgenland into a deadly zone of minefields and barbed wire (on the Hungarian side of the border): part of the Iron Curtain. Even during the era of the Iron Curtain, local trains between the north and south of Burgenland operated as "corridor trains" (Korridorzüge) – they had their doors locked as they crossed through Hungarian territory. Between 1965 and 1971, the minefields were cleared because people were often harmed by them,[citation needed] even on the Austrian side of the border. Despite Burgenland (especially the area around the Neusiedler See) always producing excellent wine, some vintners in Burgenland added illegal substances to their wine in the mid-1980s. When this was revealed, Austria's wine exports dwindled dramatically. After recovering from the scandal, vintners in Austria, and not only in Burgenland, started focusing on quality and mostly stopped producing low-quality wine.[citation needed] On 27 July 1989, the foreign ministers of Austria and Hungary, Alois Mock and Gyula Horn, cut the Iron Curtain in the village of Klingenbach in a symbolic act with far-reaching consequences. At the same time, the border crossing at Nickelsdorf (Austria) / Hegyeshalom (Hungary) was opened by the Hungarian border patrol and this enabled the escape of East Germans. Directly behind the wires special medic troops of the Austrian Red Cross awaited them and provided first assistance. Thousands of East Germans fled to the West in this way. Again, the inhabitants of Burgenland received them with great hospitality. Later, this was often referred to as the beginning of German reunification.[citation needed] After 1990 Burgenland regained its traditional role as a bridge between the western and eastern parts of Central Europe. In 2003 it joined an Interreg project Centrope. Cross-border links were further strengthened when Hungary, Slovakia and the Czech Republic joined the European Union in 2004. All three countries became part of the Schengen zone in late 2007, and border controls ceased to exist in the region. In 2021, Burgenland grew by about 6,000 m2. This was due to the change of flood protection measures along the river Lafnitz, which forms part of the border between Burgenland and Styria, in the late 1970s. As the course of the river changed somewhat along with the change of the flood protection measures, some areas belonging to Styria ended up to the east of the river and some areas belonging to Burgenland ended up to the west of the river. In 2010, it was decided by legislators together with the local councils that the areas to the west of the river would be part of Styria and the areas to the east of the river would be part of Burgenland, reflecting the perceptions and attitudes of the population. This decision was put into law in 2021. Geography Burgenland is the third-smallest of Austria's nine states at 3,962 km2 (1,530 sq mi). The province's highest point is exactly on the border with Hungary, on the Geschriebenstein, 884 metres (2,900 ft) above sea level. The highest point entirely within Burgenland is 879 metres above sea level; the lowest point (which is also the lowest point of Austria) at 114 metres (374 ft), is in the municipal area of Apetlon. Burgenland borders the Austrian states of Styria to the southwest and Lower Austria to the northwest. To the east it borders Hungary (Vas County and Győr-Moson-Sopron County). In the extreme north and south there are short borders with Slovakia (Bratislava Region) and Slovenia (Mura Statistical Region) respectively. Burgenland and Hungary share the Neusiedler See (Hungarian: Fertő-tó), a lake known for its reeds and shallowness, as well as its mild climate throughout the year. The Neusiedler See is Austria's largest lake. It is a tourist attraction, bringing ornithologists, sailors, and wind and kite surfers into the region north of the lake. Politics Burgenland's state assembly (Landtag) consists of 36 members. Since the 2025 Burgenland state election, the state assembly is made up of the following parties: Economy The province's gross domestic product (GDP) was €9 billion in 2018, accounting for 2.3% of Austria's economic output. GDP per capita adjusted for purchasing power was €27,300 or 90% of the EU27 average in the same year. Burgenland is the province with the lowest GDP per capita in Austria. Administrative divisions Burgenland consists of nine districts, two statutory cities and seven rural districts. From north to south: These combine the attributes of district and city. Demographics On 1 January 2023, the population of Burgenland surpassed the 300,000 mark for the first time, reaching 301,311 inhabitants. Burgenland has fewer inhabitants than Graz, Austria’s second-largest city. It is the least populous federal state in Austria, but has nevertheless recorded population growth since the turn of the millennium. With a population increase of 1.3%, Burgenland recorded the second-highest proportional growth after Vienna in the period from January 2022 to January 2023. While population numbers are declining or stagnating in Central and Southern Burgenland, the population in Northern Burgenland has been increasing continuously, in some cases quite strongly. The historical population is given in the following chart: Burgenland has notable Croatian (130,000) and Hungarian (5,000–15,000) populations.[citation needed] Croats number 30,000. The Croats arrived after the devastating Ottoman war in 1532, when the Ottoman army destroyed some settlements in their ethnic territory. The emigration in great haste of the remaining Catholic population of western Slavonia into Burgenland was – as far as possible – organized by estate owners. The archives of the Sabor (the Croatian parliament) from this period contain numerous references to such resettlements. As reported in the spring of 1538 by the Ban of Croatia, Petar Keglević, who himself owned large estates in western Slavonia, that the country's population at the Ottoman border was preparing to emigrate. Their resettlement by estate owners was finished only in 1584. They have preserved their strong Catholic faith and their language until today, and in the 19th century their national identity grew stronger because of the influence of the National Revival in Croatia. Between 1918 and 1921 Croats opposed the planned annexation of West-Hungary to Austria, and in 1923 seven Croatian villages voted for a return to Hungary. The Croatian Cultural Association of Burgenland was established in 1934. In the Nazi era (1938–45) the Croatian language was officially prohibited, and the state pursued an aggressive policy of Germanization. The Austrian State Treaty of 1955 guaranteed minority rights for every native ethnic minority in Austria but Croats had to fight for the use of their language in schools and offices even in the 1960s and 1970s. In 2000, 51 new bilingual village name signs were erected in Burgenland (47 Croatian and 4 Hungarian). At the 2001 census, 19,374 people across Austria stated that they spoke Burgenland Croatian, of whom 16,245 were resident in Burgenland itself. According to the self-assessment of the ethnic group, their number amounts to around 40,000. The Burgenland Croatian language is a 16th-century dialect which is different from standard Croatian. In minority schools and media the local dialect is used, and it has had a written form since the 17th century (the Gospel was first translated to this dialect in 1711). Today the language is endangered by assimilation, according to the UNESCO's Red Book of Endangered Languages. The Croats of Burgenland belong to the same group as their relatives on the other side of the modern-day border with Hungary. Hungarians live in the villages of Oberwart/Felsőőr, Unterwart/Alsóőr and Siget in der Wart/Őrisziget. The three villages together are called Upper Őrség (Hungarian: Felső-Őrség, German: Wart), and they have formed a language island since the 11th century. The other old Hungarian language island in Oberpullendorf/Felsőpulya has almost disappeared today. The Hungarians of Burgenland were "őrök", i.e. guards of the western frontier, and their special dialect is similar to the Székelys in Transylvania. Their cultural centre is Oberwart/Felsőőr. Another distinct Hungarian group was the indentured agricultural workers living on the huge estates north of Neusiedler See. They arrived mainly from the Rábaköz region. After the dissolution of the manors in the mid-20th century this group ceased to exist. According to the 2001 census, there were 4,704 Burgenland Hungarians (self-assessed at 25,000). In addition to Germans, Croats and Hungarians, Burgenland used to have substantial Roma and Jewish populations, but these were wiped out by the Nazi regime. Before their deportation during 1938, the traditionally very religious Burgenland Jews were concentrated in the famous "Seven Communities" (Siebengemeinden/Sheva kehillot) in Eisenstadt, Mattersburg, Kittsee, Frauenkirchen, Kobersdorf, Lackenbach and Deutschkreutz, where they formed a substantial part of the population: e.g. in Lackenbach, 62% of the population was Jewish as of 1869. After the war, Jews from Burgenland founded the Jerusalem haredi neighbourhood of Kiryat Mattersdorf, reminding of the original name of Mattersburg, once a centre of a famous yeshiva. Although the majority of Burgenlanders, as in the rest of Austria, are predominantly Roman Catholic, there is a relatively high proportion of Protestants here at 14%. They are organized in the 29 parishes of the Evangelical Superintendenture A.B. Burgenland and in the Evangelical parish H.B. Oberwart. Around 30,000 Burgenlanders make up the highest proportion of Protestant Christians in Austria. This large number is historically due to the region’s former affiliation with Hungary and the associated relative religious freedom in the 17th century. When the Habsburgs implemented the Counter-Reformation with full rigor in the Austrian hereditary lands, many Protestants emigrated to nearby German West Hungary, where more tolerant religious laws were in force. In the past, there was a large and significant Jewish culture, especially in the so-called “Seven Communities” (Eisenstadt, Mattersburg, Kittsee, Frauenkirchen, Kobersdorf, Lackenbach, and Deutschkreutz), which had a high proportion of Jewish population. In Lackenbach, 62% of the population were of the Jewish faith in 1869; however, the largest Jewish community in Burgenland was in Mattersburg. Until the end of the 19th century, Jews there made up more than one third of the inhabitants. In 1938, all Jews were expelled from Burgenland or murdered, and today very little remains to recall the former Jewish life in Burgenland. According to 2021 figures of Statistics Austria, Burgenland's population is mostly Christian (80.3%), with the highest proportion of Protestants in Austria (11.4%). 65.5% of the population are Roman Catholic, and further 3.4% are adherents of other Christian denominations (mostly Orthodox Christians). Islam is practiced by 2.2%, while 0.7% profess another religion. 16.8% of Burgenland's inhabitants profess no affiliation with any religion or denomination. The patron saint of Burgenland is Saint Martin of Tours. Names In Slovak, Burgenland is known as Hradsko; in Croatian as Gradišće; in Hungarian as Őrvidék, Felsőőrvidék or Várvidék; in Slovene as Gradiščanska. As the region was not a territorial entity before 1921, it never had an official name. Until the end of World War I the German-speaking western borderland of the Kingdom of Hungary was sometimes unofficially called Deutsch-Westungarn (German West Hungary). The historical region included the border city of Sopron in Hungary (known as Ödenburg in German). The name Vierburgenland (Land of Four Castles) was created in 1919 by Odo Rötig, a Viennese resident of Sopron. It was derived from the four vármegye of the Kingdom of Hungary (in German Komitaten, 'counties') known in Hungarian as Pozsony, Moson, Sopron and Vas, or in German as Pressburg, Wieselburg, Ödenburg and Eisenburg. After the town of Pozsony/Pressburg (Bratislava) was assigned to Czechoslovakia, the number vier was to be changed to drei (=three), but after it became clear that none of the Burgen would be part of the Burgenland, the number was dropped completely but the name Burgenland was kept because it was deemed to be appropriate for a region with so many old frontier castles. The "Burgenland" name was adopted by the first provincial Landtag in 1922. In Hungarian the name Őrvidék is commonly used, but the German name is also generally accepted. There are, however, modern alternatives used by minor groups. The Hungarian translation of the German name, "Várvidék", was invented by László Juhász, an expert of the region in the 1970s, and it is becoming increasingly popular especially in tourist publications. The Croatian and Slovenian names "Gradišće" and "Gradiščansko" are calques of the German name. The village of Jennersdorf is no more than 5 kilometers from the Slovenian and Hungarian borders (see the United Slovenia movement). Alternatively, the Serbs, Czechs and Slovaks call the western shores of the Neusiedler See, the lake adjoining the town of Rust, Luzic or Lusic. However, the descendants of Luzic Serbs, Bosniaks, Croats, Czechs and Slovaks were eventually assimilated into the ethnic German or Hungarian cultures over four centuries. The province has a long history of Slavic, as well Austrian-German and Hungarian-Magyar settlement. The province's easternmost portion (the shores of the Neusiedler See) carried its own topographical term Seewinkel in Austrian-German. This is the area least influenced by Austrian-German since the Hungarian and Slovak borders are less than 10 kilometers away. Symbols Heraldic description of the coat-of-arms of Burgenland: The arms were introduced in 1922 after the new province was created. They were composed from the arms of the two most important medieval noble families of the region, the counts of Nagymarton and Fraknó (Mattersdorf-Forchtenstein, eagle on the rock) and the counts of Németújvár (Güssing, three bars of red and white fur). The flag of the province shows two stripes of red and gold, the colours of the coat-of-arms. It was officially confirmed in 1971. Culture The cultural offerings are diverse and especially in the summer famous for the Seefestspiele Mörbisch and the Nova Rock Festival with numerous international rockbands. The permanent exhibition at Forchtenstein Castle shows an impressive collection of the dukes of Esterházy, at whose court at Esterházy Palace worked the world-famous musician Joseph Haydn, who composed from the Burgenland Croatian folk-song "V jutro rano se ja stanem" ("In the morning I rise up early") the melody of "Gott erhalte Franz den Kaiser" ("God save Franz the Emperor"), which became the melody of today's national anthem of Germany. There are also cultural events organized by the minorities such as Croatian or Hungarian folk evenings. The dialect spoken in Burgenland is called Hianzisch. People from Burgenland tend to be the butt of a joke cycle by people from other regions of Austria, similar to the German East Frisian jokes. These jokes portray people from Burgenland as dumb or slow on the uptake. Media References Sources Further reading External links 47°30′N 16°25′E / 47.500°N 16.417°E / 47.500; 16.417 |

Contents TF1 TF1 (French: [te ɛf œ̃] ⓘ; standing for Télévision Française 1) is a French commercial television network owned by TF1 Group, controlled by the Bouygues conglomerate. TF1's average market share of 24% makes it the most popular domestic network. TF1 is part of the TF1 Group of mass media companies, which also includes the news channel LCI. It previously owned the satellite TV provider TPS, which was sold to Canal+ Group. The network is a supporter of the Hybrid Broadcast Broadband TV (HBBTV) initiative, promoting and establishing an open European standard for hybrid set-top boxes for the reception of terrestrial TV and broadband multimedia applications with a single user interface. History The government operated the sole television channel in France for 28 years. It was created as Radiovision-PTT [fr] on 26 April 1935, making it among the oldest television stations in the world, and one of the very few prewar television stations to remain in existence to the present day. The first public demonstration of a 30-line mechanical television took place on 14 April 1931. The image rendering was an improvement upon Baird's thanks to the development of the "moving light point" system and the use of a camera with Weiller mirror drums by the engineer René Barthélemy, head of the radio laboratory of the Compagnie des compteurs [fr] (CdC) of Montrouge. In charge of French broadcasting, the PTT administration carried out some rudimentary television experiments from December 1931 by broadcasting experimental 30 to 45 minute broadcasts at variable times from Monday to Saturday with Baird equipment from the medium wave transmitter of Radio PTT. The Barthélemy system was officially adopted in preference to that of Baird, due to the greater stability of the images, for the continuation of experimental transmissions in 1932. The Minister of the PTT, Henri Queuille, then authorised the Compagnie des compteurs [fr] to continue its experiments using the PTT superior school transmitter located at 103 rue de Grenelle in the 15th arrondissement of Paris and assigned the company a rudimentary studio at number 93 of the same street. Barthélemy continued his experiments there with a new disc camera from Nipkow which offered much better shooting possibilities than with the previous system. The programs were broadcast in 30 lines on Tuesday and Friday at 5:00 pm by two transmitters, the images by the medium wave transmitter of the higher school of the PTT on the wavelength of 431 meters and the sound by the transmitter of the Compagnie des compteurs [fr] in Montrouge connected to the studio by a telephone line. These experimental broadcasts only reached a very limited public of amateurs of technical innovation who tinkered with receivers connected to a radio, thus constituting a radiovision receiver. At the same time, the BBC Television Service had been broadcasting an experimental but regular television service since 22 August 1932, with broadcasts taking place Monday to Friday from 11.00 a.m. to 11.30 a.m., and at night on medium wave on 205 meters after BBC radio programmes closed down for the night. The new French Minister of the PTT of the Flandin Government, Georges Mandel, during a visit to the general manager of the British Broadcasting Corporation at the end of 1934, attended a live broadcast of the Epsom Derby on a televisor built by John Logie Baird. Convinced by this demonstration and of the interest of this invention for the future, but also very aware that the ministerial instability must lead him to quickly imprint his mark on the heavy administration of the PTT for which he was responsible by modernizing, Georges Mandel decided to inaugurate as soon as possible a regular and experimental public television service in France. In March 1935, he went to the Compagnie des compteurs [fr] to measure the state of progress of the research. René Barthélemy gave him a demonstration of his new mechanical disc camera with 60 lines of definition (25 images per second), his new telecine (of which he was the inventor) with 180 lines, as well as a receiver with 60 cathode ray tube lines; a tube for which the Compagnie des compteurs [fr] has just launched production. He also informed him of his ongoing work on a 180-line camera. Pressed to carry out his project, the minister granted Barthélemy the means requested for his success. The amphitheater of the PTT superior school, located in the premises of the Ministry of Posts and Telecommunications at 103 rue de Grenelle [fr], was converted into a television studio on 17 April 1935 and its bleachers were dismantled to enlarge it. The CdC's 60-line mechanical camera was placed in the adjoining room, behind double-thick insulating glass to mask the sound of the motor spinning the camera disk. This same room also housed the 60-line, 500-watt transmitter designed by the Compagnie des compteurs [fr]. The project provided for a short wave transmitter on the Eiffel Tower and a definition of 180 lines in the long term, as soon as Barthélemy had finalized his work. One thousand guests of the Minister, personalities, journalists and industrialists flocked to the studio at 103 rue de Grenelle [fr] on Friday, 26 April 1935 to attend the first official regular French television broadcast transmitted by radio with a definition of 60 lines3. At 8:15 pm, on the small greenish screen appeared the face of the actress and friend of the minister, Béatrice Bretty [fr], member of the Comédie-Française, with at her side, Jean Toscane, the most famous voice of Radio PTT, and René Barthélemy. Lips and eyes made up in black for the needs of television broadcasting, Miss Bretty recounted of her last tour in Italy with the troupe: "We had a great trip...". These were the first words broadcast on French television. This first television program was broadcast live until 8:30pm on the 175-meter medium-wave frequency within a radius of 100 km (60 miles). Radiovision-PTT [fr], the first French television channel, had just been born. Radiovision-PTT [fr] began operations on 26 April 1935 as the first television station in France, using a 30-line mechanical television system based on the Nipkow disk. It was operated by the French PTT agency with a transmitter located atop the Eiffel Tower, and was on air three days a week from 11 am to 11:30 am and 8 pm to 8:30 pm and on Sundays from 5:30 pm to 7:30 pm. On 4 January 1937, the broadcasting hours were changed such that television programmes were aired from 5 pm until 10 pm on Wednesdays to Fridays, and from 4 pm to 8:30 pm or 9 pm on Saturdays to Tuesdays. Impressed by the sharpness of the 60-line images obtained from the cathode-ray tube control receiver during this broadcast, Georges Mandel gave the PTT technicians and René Barthélemy six months to set up the necessary installations for regular public broadcasting in 180 lines. Two months late, the official inauguration of 180-line television took place on Sunday, 8 December 1935, from 5:30pm to 7:30pm in front of the press, at the Radiovision-PTT [fr] studio at 103, rue de Grenelle [fr] in Paris, with a gala session combining excerpts from plays, comic operas, poems, songs and sketches performed by many famous comedians and music-hall artists invited by Béatrice Bretty [fr], and whose numbers were announced at the screen by Suzy Wincker [fr], the first official continuity announcer, on the air since June. The rue de Grenelle [fr] studio required 50,000 lux of light to compensate for the insufficient sensitivity of the 180-line mechanical camera with a double-spiral Nipkow disk rotating at 50 rotations per second. The dissipation of the heat of this very violent lighting was annoying and even dangerous for the artists. This is why a forced-air refrigeration system (temperature and humidity) was installed in the studio to lower its temperature from 55 to 25 °C (130°F to 75°F) by means of six aerators. The images filmed in the studio were routed live by a 2,500 meter (1½ mile) long telephone cable to a new transmitter designed by SFR-CSF and temporarily located at the north pillar of the Eiffel Tower, from where a feeder connected it to the four 2 kW shortwave transmitting antennas located at the top of the tower 320 meters (1050 feet) high and which can be received 100 km (60 miles) around Paris. The sound was transmitted in medium wave on the frequency of 206 meters (675 feet) by the transmitter of Radio Tour Eiffel. The very large public crowds in front of the receivers installed at the Conservatoire national des arts et métiers at 292 rue Saint-Martin, at the National Tourist Office on the Champs-Élysées, at the Salon de la France d'Outre-Mer at the Grand Palais, at the Maison de la Chimie, and at the town hall of the 5th arrondissement of Paris, which simultaneously broadcast the images in 180 lines. Indeed, if Barthélemy's Emyvisor from EMYRADIO [fr] was put on sale at the end of 1935, its price was still exorbitant (8,000 to 10,000 francs at the time, or around 6,000 euros today) and only the privileged few could enjoy television at the time. Robert Jardillier [fr], new PTT Minister of the Popular Front, launched on 24 October 1936 a call for tenders from radio-electric manufacturers in order to provide television with higher definition equipment exploiting the possibilities offered by the iconoscope and electronic television. Already exploited by the British, Germans and Americans. A test period would enable the best standard to be chosen. The broadcasts became regular from 4 January 1937 with broadcast from 11am to 11:30am and from 8pm to 8:30pm on weekdays and from 5:30pm to 7:30pm on Sundays. The Deputy Secretary General for Broadcasts, Wladimir Porché [fr], brought the greatest French artists, such as Sacha Guitry, Serge Lifar and Maurice Chevalier, to the cameras of the Radiovision-PTT [fr] studio. At that time, there were only about 100 individual television receivers. Grammont Radio-Télévision [fr] carried out its tests in 441 lines, the Compagnie française de télévision [fr] (association of the Compagnie des compteurs [fr] and SFR-CSF) in 450 lines and Thomson-Houston in 455 lines. The PTT administration chose the 455-line high-definition equipment manufactured by Thomson for public demonstrations at the 1937 Paris Exposition Internationale des Arts et Techniques dans la Vie Moderne, which was then transferred to the Radiovision-PTT [fr] studio for testing. Following successful trials of a "high-definition" 455-line electronic television system designed by Thomson-Houston which improved on the 405-line system originally designed by EMI-Marconi, Radio-PTT Vision renamed itself as Radiodiffusion nationale Télévision (RN Télévision) in July 1937. However, broadcasts using the Nipkow disk system continued alongside the new electronic system until 10 April 1938. In July 1938, a decree of the French PTT agency fixed the French terrestrial television standard as transmitting on 455 lines VHF (46 MHz, positive modulation, 25 frames per second), to be adopted throughout France within three years. The adoption of the electronic standard marked the end of mechanical television in France, and the advent of electronic television to obtain much better image quality. While the BBC Television Service was able to broadcast the arrival of the President of the French Republic Albert Lebrun in London for his official visit on 21 March 1939, RN Télévision was otherwise unable to film a single image. The Minister of the PTT Alfred Jules-Julien [fr] thus promised on 31 March a bus equipped for remote reporting in the open air within two weeks, a new television studio and programs broadcast in the evening after dinner. The administrative system of public broadcasting was modified by a decree of 29 July 1939 signed by the President of the Council Édouard Daladier, making French Broadcasting, and therefore the television service attached to it, a State monopoly which ceased to depend on the Ministry of PTT to pass under the administration of the National French Radio, newly created for this purpose, endowed with an autonomous budget and placed directly under the authority of the President of the council. The rue de Grenelle studio went on annual vacation on 31 July 1939 and never reopened. Radiodiffusion nationale Télévision then only broadcast films, documentaries and news via its Grammont telecine and identified itself with the callsign Télé-Cinéma Radiodiffusion nationale. When France entered World War II on 3 September 1939, military authorities ordered the cessation of broadcasts and took control of the Eiffel Tower transmitter. The French hardly noticed it because there were no more than 300 receiving stations throughout the territory, which were also watched in a few rare public places. A few broadcasts were still broadcast episodically for transmitter maintenance purposes, but these were not advertised in the press so that the Germans could not use the transmitter signal to locate and bombard Paris. On 6 June 1940, technicians from RN Télévision sabotaged the transmitter to make it unusable by the Germans who were at the gates of Paris. The German occupying forces initially took no interest in the Eiffel Tower transmitter until an order in May 1941, aimed at reducing transmission sites in the occupied zone in order to recover raw materials, and thus recover certain elements of the French 455-line transmitter of interest to Telefunken lead to discussions on the rehabilitation and use of this transmitter for television. Opposed to this dismantling, Kurt Hinzmann [de], German television pioneer and former director of the programs of Berlin's Fernsehsender Paul Nipkow television station, who succeeded in convincing the German authorities to continue the broadcast of the programs of the station during the war by proposing its use to entertain and distract the war wounded in hospitals, took up this idea to apply it to the French capital and thus save the Parisian transmitter. He recommended putting the Eiffel Tower transmitter back into service to broadcast a television channel intended to entertain the German soldiers hospitalized in the Kriegslazarette in Paris. In addition, this television channel would open up the French market to the German electrical industry by adopting the German 441-line broadcasting standard developed by Telefunken. Finally, from a military point of view, the repair of this transmitter could allow it to be used as a jammer for enemy planes. By order of the Oberkommando der Wehrmacht to the Ministry of PTT on 20 May 1942, the work to restore the transmitter in the Eiffel Tower to service was entrusted to the Compagnie des comptes de Montrouge and the German firm Telefunken, following a collaboration agreement between the two companies to jointly build the technical infrastructure of this new television channel. The equipment of the Compagnie des Compteurs being considered uninteresting, Telefunken supplied the new television transmitter to the German standard of 441 lines, recovered from the Reichspost in Germany, and which was installed by technicians from Berlin. Fernsehsender Paris (Paris-Télévision) moved into a large 3,000-seat ballroom, a remnant of the former Magic-City amusement park closed in 1926, unused since the start of the war. This installation made it possible to start the programs on a regular basis on 7 May 1943 only in telecine, because the work on the V-shaped stage, allowing the cameras to be moved back for wider shots, had not been completed. It broadcasts in German and French four days a week from 10 am to noon, three days from 3pm to 8pm and every evening from 8:30pm to 10pm, broadcasting variety shows and theater for field hospitals (Kriegslazarett) of the Wehrmacht installed in the Paris region and German residents in Paris (about 1,000 receivers, including a hundred for French viewers). The station was officially inaugurated on 30 September 1943 with the start of live broadcasts. A week before the liberation of Paris, Fernsehsender Paris ceased broadcasting on Saturday 12 August 1944 at 11:30 p.m. On 17 August, the order was given to Hinzmann to blow up the Eiffel Tower's transmitter, which he refused, contenting himself with firing a few symbolic shots into unimportant equipment. The Germans left the studios, leaving the French with a fully operational and among the most efficient television station in the world, which enabled French television to be the first in Europe to resume its broadcasts from the old studio and with the equipment from Fernsehsender Paris, from 1 October 1944 intermittently and in closed circuit test transmissions, because the Americans had administered the Eiffel Tower at the time and prohibited the use of its transmitter until 1 October 1945. Television broadcasts in France resumed on 1 October 1944 under the name Télévision française, and following the creation of Radiodiffusion française on 23 March 1945, the television service was renamed as RDF Télévision française. Following the return of the Eiffel Tower to the French precisely one year (1 October 1945) after the restart, the official resumption of television broadcasts took place with one hour of programming each day. On 20 November 1948, the Secretary of State for Information, François Mitterrand, decreed the adoption of the 819-line high-definition VHF standard, which was in use from 1949 until 1983. Radiodiffusion française was renamed as Radiodiffusion-télévision française (RTF) on 9 February 1949, and thus began the growth of television as an accepted mass medium in France. RTF was also the first channel in the world to air footage of a Pope, on 17 April 1949, with a film sent from the Vatican of Pope Pius XII talking about the potential of television. On 29 May 1949, the first news programme aired on RTF TV, and on 30 July 1949 a television licence fee was introduced. Residents living outside Paris could view RTF TV for the first time in February 1952 when Télé Lille (now known as France 3 Nord-Pas-de-Calais), a regional broadcaster operating since 10 April 1950, was co-opted into the RTF TV network and became RTF's first relay outside Paris. Still as of 1954, RTF's terrestrial network consisted of only three stations reaching 90,000 television sets, while West Germany had set up nine stations by year-end 1953. Its programming was also seen to be stale, with an excessive amount of old movies (120 per year), "stale" newsreels, poor lighting, lack of sport and star performers. Famed French singer of the time Maurice Chevalier actually made his first television appearance in the United Kingdom, as opposed to France. RTF television services were also extended to French Algeria in 1956, which later became TV1 Algeria upon Algerian independence in 1962. Following the creation of RTF Télévision 2 (now France 2) in 1964, the first channel was renamed as Première chaîne de la RTF (First Channel of the RTF). With the creation of the ORTF on 25 July 1964, the channel was renamed again to Première chaîne de l'ORTF (First Channel of the ORTF). This period marked the introduction of commercial advertising on 1 October 1968. On 8 January 1969, the ORTF created a subsidiary company called Régie française de publicité [fr] (RFP) to handle all advertising on the ORTF channels. The RFP held a monopoly on French TV advertising until the launch of privately owned TV channels in France in the 1980s, and was eventually liquidated in 1993. TF1, which originally stood for Télévision française 1 (French Television 1), was created on 1 January 1975 when law 74-696 of 7 August 1974, splitting the ORTF into seven separate organisations, came into effect. The name TF1 was a recommendation of the European Broadcasting Union, who demanded the television unit of the former ORTF rebranded as Télévision Française, with the channels being renamed TF1, TF2 and TF3. However, the fact that the three channels were to be independent caused TF1 to become the only channel to use the proposed Télévision Française name. The rebranding to the new name came into effect on 6 January 1975. TF1 adopted a multicoloured logo and cel-animated idents created by Catherine Chaillet [fr], and from 1976 until 1985, analogue computer-generated idents produced using the Scanimate system were also used, created by the American company Robert Abel and Associates with background music composed by Vladimir Cosma. The 1975 TF1 logo was later modified in 1984 and again in 1987. Colour television was first introduced to TF1 on 1 September 1975 when FR3 (now France 3) agreed to supply some of its colour programming to TF1, and the conversion to colour on TF1 was completed in 1977, though the old 819-line analogue network remained entirely black-and-white until it was decommissioned in 1983. Since TF1's privatisation in April 1987, the abbreviation is no longer expanded, so as to avoid confusion with the current public television broadcaster France Télévisions. From 1984 to 1986, the French television landscape evolved significantly with the launch of three private television channels: Canal+, La Cinq and TV6. In March 1986, the Chirac government [fr] decided to privatize one of the three public channels. Although initial reports had suggested Antenne 2 (now France 2), on 14 May the government announced that TF1 was selected. The channel was therefore more apt to confront with competition, but still considered left-leaning by the right-wing majority.[citation needed] In April 1987, the construction conglomerate Bouygues won the resulting auction for the sale of TF1. On 16 April, its president, Francis Bouygues, presented a check of three billion francs to the government, completing the privatisation of TF1. TF1's current logo was unveiled on February 2nd, 1990. It launched a news network, La Chaîne Info (LCI), in 1994. The channel was available in Italy alongside LCI on digital terrestrial television from 2004 to December 2006 on Dfree multiplex.[citation needed] In 2005, TF1 launched TF1 Vision, a video on demand service. On 20 May 2021, it was announced that TF1 Group, owners of the channel, proposed a merger with Groupe M6, which owns M6. On 16 September 2022, it was announced that the merger was officially abandoned. Since October 2022, the free DTT channels of the TF1 Group have been accessible free to air via the Astra 1 satellite. This broadcast follows a temporary interruption in encrypted broadcasting to Canal+ and TNTSAT subscribers, following a commercial dispute. However, despite the resumption of encrypted broadcasts within the Canal+ and TNTSAT bouquets, this free-to-air broadcasting continues. LCI is therefore received free of charge in almost all of continental Europe. On 23 November 2024, Sky News reported that CVC Capital Partners, TF1, RedBird Capital Partners, All3Media, Mediawan and Kohlberg Kravis Roberts had been linked to a potential takeover bid for ITV plc and a possible break-up of core assets such as ITV Studios and ITVX. This could see TF1 name launched in UK. Logo history Programmes Criticism Some commentators accuse TF1 of being an excessively populist, commercialised channel. There is a clear emphasis on "light" entertainment programmes over more serious content, and the channel's success is sometimes seen as being founded on the ménagères de moins de 50 ans (housewives under 50) audience segment. A large proportion of the schedule consists of gameshows, sensational documentaries and dubbed versions of TV series. The channel's news service is perceived as consisting of more celebrity news and human-interest stories than its public-sector competitors. On 16 April 2009, the employee responsible for the "Web innovation" department was fired for criticizing the HADOPI law in a private email (on 19 February) sent to a Member of Parliament. The management of TF1 was notified about the e-mail by the Ministry for Culture and Communication, whose Minister Christine Albanel is also one of the authors of the HADOPI law. In 2004, Patrick Le Lay, CEO of TF1 made the following statement about the channel's aims: There are many ways to speak about TV, but in a business perspective, let's be realistic: at the basis, TF1's job is helping Coca-Cola, for example, to sell its product. What we sell to Coca-Cola is available human brain time. Nothing is more difficult than obtaining this availability. This is where permanent change is located. We must always look out for popular programs, follow trends, surf on tendencies, in a context in which information is speeding up, getting manifold and trivialized. Critics of TF1 also contend that its news coverage is slanted towards supporting right-wing politicians – they were in particular accused of supporting Édouard Balladur in the 1995 presidential elections, and of overstating crime during the 2002 electoral campaign to tilt the balance in favour of former French president Jacques Chirac, who campaigned on a law and order platform. Key figures within TF1 are close friends to some of the most powerful politicians in France, and the relationship between Bouygues and the public-sector contracting system often raises suspicions. Immigration and violence are arguably conflated in the channel's news programmes. In addition, it is occasionally alleged that news reports from TF1 tend to ignore issues yielding a bad light on their parent group (Bouygues), while stressing the problems of competitors (such as Vinci SA). Such criticism was heavy in the satirical show Les Guignols de l'info, broadcast on rival network Canal+. However, TF1 now competes in this category with M6, which was initially a generalist channel focusing on musical programmes, but now has programming more resembling TF1 (notably, reality shows that TF1 started running just after M6 introduced them).

Reporter Zoë Bernard spent months talking to 51 people (31 of them gay men) to map out a subculture that’s been an open secret in Silicon Valley for years: gay men, at the upper echelons of tech, quietly raising up their own networks the way powerful people have always done. One angel investor puts it plainly: “The gays who work in tech are succeeding vastly… they support each other, whether that’s to hire someone or angel invest in their companies or lead their funding rounds.” Another source frames it almost philosophically: “Straight guys have the golf course. Gay guys have the orgy. It doesn’t mean it’s problematic. It’s a way we bond and connect.” The piece doesn’t let the culture off the hook entirely. As is true wherever power dynamics exist, nine of the gay men interviewed describe experiencing unwanted advances from more senior colleagues — and Bernard doesn’t shy from examining where networking ends and coercion begins.

Contents PyGTK PyGTK is a set of Python wrappers for the GTK graphical user interface library. PyGTK is free software and licensed under the LGPL. It is analogous to PyQt/PySide and wxPython, the Python wrappers for Qt and wxWidgets, respectively. Its original author is GNOME developer James Henstridge. There are six people in the core development team, with various other people who have submitted patches and bug reports. PyGTK has been selected as the environment of choice for applications running on One Laptop Per Child systems. PyGTK was phased out with the transition to GTK version 3 and be replaced with PyGObject, which uses GObject Introspection to generate bindings for Python and other languages on the fly. This is expected to eliminate the delay between GTK updates and corresponding language binding updates, as well as reduce maintenance burden on the developers. Syntax The Python code below will produce a 200x200 pixel window with the words "Hello World" inside. PyGTK has been used in a number of notable applications, some examples: PyGObject PyGObject provides a wrapper for use in Python programs when accessing GObject libraries. GObject is an object system used by GTK, GLib, GIO, GStreamer and other libraries. Like the GObject library itself, PyGObject is licensed under the GNU LGPL, so it is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single-purpose scripts to large full-featured applications. PyGObject can dynamically access any GObject libraries that use GObject Introspection. It replaces the need for separate modules such as PyGTK, GIO and python-gnome to build a full GNOME 3.0 application. Once new functionality is added to GObject library it is instantly available as a Python API without the need for intermediate Python glue. PyGObject has replaced PyGTK, but it has taken a considerable amount of time for many programs to be ported. Most of the software listed here has an older version which used PyGTK.

Contents Amsterdam Amsterdam (Dutch: [ˌɑmstərˈdɑm] ⓘ; lit. 'Dam in the Amstel') is the capital[a] and largest city of the Netherlands. It has a population of 933,680 in June 2024 within the city proper, 1,457,018 in the urban area and 2,480,394 in the metropolitan area. Located in the Dutch province of North Holland, Amsterdam is colloquially referred to as the "Venice of the North", for its large number of canals, now a UNESCO World Heritage Site.[unreliable source?] Amsterdam was founded at the mouth of the Amstel River, which was dammed to control flooding. Originally a small fishing village in the 12th century, Amsterdam became a major world port during the Dutch Golden Age of the 17th century, when the Netherlands was an economic powerhouse. Amsterdam was the leading centre for finance and trade, as well as a hub of secular art production. In the 19th and 20th centuries, the city expanded and new neighborhoods and suburbs were built. The city has a long tradition of openness, liberalism, and tolerance. Cycling is key to the city's modern character, and there are numerous biking paths and lanes spread throughout. Amsterdam's main attractions include its historic canals; the Rijksmuseum, the state museum with Dutch Golden Age art; the Van Gogh Museum; the Dam Square, where the Royal Palace of Amsterdam and former city hall are located; the Amsterdam Museum; Stedelijk Museum, with modern art; the Concertgebouw concert hall; the Anne Frank House; the Scheepvaartmuseum, the Natura Artis Magistra; Hortus Botanicus, NEMO, the red-light district and cannabis coffee shops. The city is known for its nightlife and festival activity, with several nightclubs among the world's most famous. Its artistic heritage, canals, and narrow canal houses with gabled façades, well-preserved legacies of the city's 17th-century Golden Age, have attracted millions of visitors annually. The Amsterdam Stock Exchange, founded in 1602, is considered the oldest "modern" securities market stock exchange in the world. As the commercial capital of the Netherlands and one of the top financial centres in Europe, Amsterdam is considered an alpha-world city. The city is the cultural capital of the Netherlands. Many large Dutch institutions have their headquarters in the city. Many of the world's largest companies are based in Amsterdam or have established their European headquarters there, such as technology companies Uber, Netflix, and Tesla. Although Amsterdam is the official capital of the Netherlands, it is not the seat of government. The main governmental institutions, and foreign embassies, are located in The Hague. In 2022, Amsterdam was ranked the ninth-best city to live in by the Economist Intelligence Unit and 12th on quality of living for environment and infrastructure by Mercer. The city was ranked 4th place globally as a top tech hub in 2019. The Port of Amsterdam is the fifth largest in Europe. The KLM hub and Amsterdam's main airport, Schiphol, is the busiest airport in the Netherlands, third in Europe. The Dutch capital is one of the most multicultural cities in the world, with about 180 nationalities represented. Immigration and ethnic segregation in Amsterdam is a current issue. Amsterdam's notable residents throughout its history include painters Rembrandt and Vincent van Gogh, 17th-century philosophers Baruch Spinoza, John Locke, René Descartes, and Holocaust victim and diarist Anne Frank. History Due to its geographical location in what used to be wet peatland, the founding of Amsterdam is later than other urban centres in the Low Countries. However, around the area of what later became Amsterdam, farmers settled as early as three millennia ago. They lived along the prehistoric IJ river and upstream of its tributary Amstel. The prehistoric IJ was a shallow and quiet stream in peatland behind beach ridges. This secluded area was able to grow into an important local settlement centre, especially in the late Bronze Age, the Iron Age and the Roman Age. Neolithic and Roman artefacts have also been found in the prehistoric Amstel bedding under Amsterdam's Damrak and Rokin, such as shards of Bell Beaker culture pottery (2200–2000 BC) and a granite grinding stone (2700–2750 BC), but the location of these artefacts around the river banks of the Amstel probably points to the presence of a modest semi-permanent or seasonal settlement. Until water issues were controlled, a permanent settlement would not have been possible, since the river mouth and the banks of the Amstel in this period in time were too wet for permanent habitation. The origins of Amsterdam are linked to the development of a dam on the Amstel River called Amestelle, meaning 'watery area', from Aa(m) 'river' + stelle 'site at a shoreline', 'river bank'. In this area, land reclamation started as early as the late 10th century. Amestelle was located along a side arm of the IJ. This sidearm took its name from the eponymous land: Amstel. Amestelle was inhabited by farmers, who lived more inland and more upstream, where the land was not as wet as at the banks of the downstream river mouth. These farmers were starting the reclamation around upstream Ouderkerk aan de Amstel, and later at the other side of the river at Amstelveen. The Van Amstel family, known in documents by this name since 1019, held the stewardship in this northwestern nook of the ecclesiastical district of the bishop of Utrecht. The family later served also under the count of Holland. A major turning point in the development of the Amstel River mouth was the All Saint's Flood of 1170. In an extremely short time, the shallow river IJ turned into a wide estuary, which from then on offered the Amstel an open connection to the Zuiderzee, IJssel, and waterways further afield. This made the water flow of the Amstel more active, so excess water could be drained better. With drier banks, the downstream Amstel mouth became attractive for permanent habitation. Moreover, the river had grown from an insignificant peat stream into a junction of international waterways. A settlement was built here immediately after the landscape change of 1170. Right from the start of its foundation, it focused on traffic, production, and trade; not on farming, as opposed to how communities had lived further upstream for the past 200 years and northward for thousands of years. The construction of a dam at the mouth of the Amstel, eponymously named Dam, is historically estimated to have occurred between 1264 and 1275. The settlement first appeared in a document from 1275, concerning a road toll granted by the count of Holland Floris V to the residents apud Amestelledamme 'at the dam in the Amstel' or 'at the dam of Amstelland'. This allowed the inhabitants of the village to travel freely through the County of Holland, paying no tolls at bridges, locks and dams. This was a move in a years-long struggle for power in the area between the count of Holland and the Amstel family who governed the area on behalf of the bishop of Utrecht. By 1327, the name had developed into Aemsterdam. The bishop of Utrecht granted Amsterdam zone rights in either 1300 or 1306. The Mirakel van Amsterdam [nl] in 1345 rendered the city an important place of pilgrimage. During the heyday of the Stille Omgang, which became the expression of the pilgrimage after the Protestant Reformation, up to 90,000 pilgrims came to Amsterdam. From the 14th century on, Amsterdam flourished, largely from trade with the Hanseatic League. From the 15th century on the city established an independent trade route with the Baltic Sea in grain and timber, cutting out the Hanseatic League as middlemen. The city became the staple market of Europe for bulk cargo. This was made possible due to innovations in the herring fishery, from which Amsterdam reaped great wealth. Herring had demand in markets all around Europe. Inventions of on-board gibbing and the haringbuis in 1415, made longer voyages feasible and hence enabled Dutch fishermen to follow the herring shoals far from the coasts, giving them a monopoly in the industry. The herring industry relied on international trade cooperation and large initial investments in ships. This required many highly skilled and unskilled workers to cooperate, as well as the import of the necessary raw materials to turn an unfinished product into a marketable one. This required merchants to then sell it throughout the continent and bookkeepers and accountants to divide the profit. In short, the herring industry was setting up the foundations for what would later become the transcontinental trade system and the Dutch Golden Age, with Amsterdam at its centre, hence the saying "Amsterdam is built on Herringbones". The Low Countries were part of the Habsburg inheritance and came under the Spanish monarchy in the early sixteenth century. The Dutch rebelled against Philip II of Spain, who led a defense of Catholicism during the Protestant Reformation. The main reasons for the uprising were the imposition of new taxes, the tenth penny, and the religious persecution of Protestants by the newly introduced Inquisition. The revolt escalated into the Eighty Years' War, which ultimately led to Dutch independence. Strongly pushed by Dutch Revolt leader William the Silent, the Dutch Republic became known for its relative religious tolerance. Jews from the Iberian Peninsula, Protestant Huguenots from France, prosperous merchants, and printers from Flanders, and economic and religious refugees from the Spanish-controlled parts of the Low Countries found safety in Amsterdam. The influx of Flemish printers and the city's intellectual tolerance made Amsterdam a centre for the European free press. During the 17th century, Amsterdam experienced what is considered its Golden Age, during which it became the wealthiest city in the Western world. Ships sailed from Amsterdam to the Baltic Sea, the Caribbean, North America, and Africa, as well as present-day Indonesia, India, Sri Lanka, and Brazil, forming the basis of a worldwide trading network. Amsterdam's merchants had the largest share in both the Dutch East India Company (VOC) and the Dutch West India Company. These companies acquired overseas possessions that later became Dutch colonies. Amsterdam was Europe's most important hub for the shipment of goods and was the leading financial centre of the Western world. In 1602, the Amsterdam office of the Dutch East India Company became the world's first stock exchange by trading in its own shares. The Bank of Amsterdam started operations in 1609, acting as a full-service bank for Dutch merchant bankers and as a reserve bank. From the 17th century onwards, Amsterdam also became involved in the Atlantic slave trade. The city was a major destination port for Dutch slave ships participating in the triangular trade, which lasted until the United Netherlands abolished the Netherlands' involvement in the trade in 1814 at the request of the British government. Amsterdam's prosperity declined during the 18th and early 19th centuries. The wars of the Dutch Republic with England (latterly, Great Britain) and France took their toll on the city. During the French Revolutionary Wars and the Napoleonic Wars, Amsterdam's significance reached its lowest point, with Holland being absorbed into the French Empire. However, the later establishment of the United Kingdom of the Netherlands in 1815 marked a turning point. The end of the 19th century is sometimes called Amsterdam's second Golden Age. New museums, a railway station, and the Concertgebouw were built; At the same time, the Industrial Revolution reached the city. The Amsterdam–Rhine Canal was dug to give Amsterdam a direct connection to the Rhine, and the North Sea Canal was dug to give the port a shorter connection to the North Sea. Both projects dramatically improved commerce with the rest of Europe and the world. In 1906, Joseph Conrad gave a brief description of Amsterdam as seen from the seaside, in The Mirror of the Sea. Shortly before the First World War, the city started to expand again, and new suburbs were built. Even though the Netherlands remained neutral in this war, Amsterdam suffered a food shortage, and heating fuel became scarce. The shortages sparked riots in which several people were killed. These riots are known as the Aardappeloproer (Potato Rebellion). People started looting stores and warehouses to get supplies, mainly food. On 1 January 1921, after a flood in 1916, the depleted municipalities of Durgerdam, Holysloot, Zunderdorp and Schellingwoude, all lying north of Amsterdam, were, at their own request, annexed to the city. Between the wars, the city continued to expand, most notably to the west of the Jordaan district in the Frederik Hendrikbuurt and surrounding neighbourhoods. Nazi Germany invaded the Netherlands on 10 May 1940 and took control of the country. Some Amsterdam citizens sheltered Jews, thereby exposing themselves and their families to a high risk of being imprisoned or sent to concentration camps. More than 100,000 Dutch Jews were deported and murdered in Nazi concentration camps, including 56,521 victims in Auschwitz and a further number of 34,082 accounted for in Sobibor. Around 60,000 Jewish inhabitants, including Jewish prewar refugees from Austria and Germany, were living in Amsterdam at the time of the Nazi occupation. Only those provided with a safe haven, avoiding deportation and denunciation, or the very few who returned from the camps at the end of the war, managed to survive. At first the German occupation authorities were very cautious, wanting to convince the city inhabitants of their sincerity. However, their outlook soon turned to cynicism and brutality. A cause in the change of their behaviour was an attack by a Dutch resistance fighter against a collaborator belonging to the paramilitary Dutch fascist organisation, the NSB. The injured man died and in response Heinrich Himmler ordered reprisals. 427 Amsterdam Jews were arrested on 22 February 1941 and sent to Mauthausen concentration camp. Only two people survived. Incensed, a broad spectrum of passive resistance was organized by the Dutch Underground. Trade unions, among them socialist and Communist Party activists, led the protest. Their outcry received support from white collar employees in the civil service and support from the local diocese of the Church. Approval was also given and encouraged by the Dutch government-in-exile under Queen Wilhelmina in London. The German authorities were taken completely by surprise by the level of resistance known as the February strike. 300,000 people participated in the protest against the arrests of Jews. However, the occupier soon responded crudely and brutally, smashing union and illegal party activity. With the edifice of resistance removed the SS and German police apparatus, supported by collaborators in the Dutch auxiliary police, arrested thousands of defenceless Jews in Amsterdam's Jewish Quarter. The two main waves of arrest, culminating in deportation, occurred on 26 May 1943 and on 20 June 1943. The most famous deportee was the young Jewish girl Anne Frank, whose safe hiding place with her family was betrayed and discovered in August, 1944. After a spell at the 'holding camp' in Westerbork Anna and her family were sent to Auschwitz, where her mother was murdered. From there she and her sister Margot were moved onto Bergen-Belsen concentration camp where they died amidst appalling and inhumane conditions in early 1945. At the end of the Second World War, and as a consequence of the Nazi occupation, Amsterdam was in a state of crisis. Communication with the rest of the country broke down, and food and fuel became scarce. Many citizens traveled to the countryside to forage. Dogs, cats, raw sugar beets, and tulip bulbs—cooked to a pulp—were consumed to stay alive. Many trees in Amsterdam were cut down for fuel, and wood was taken from the houses, apartments and other buildings of deported Jews. The city was finally liberated by Canadian forces on 5 May 1945, shortly before the end of the war in Europe. Many new suburbs, such as Osdorp, Slotervaart, Slotermeer and Geuzenveld, were built in the years after the Second World War. These suburbs contained many public parks and wide-open spaces, and the new buildings provided improved housing conditions with larger and brighter rooms, gardens, and balconies. Because of the war and other events of the 20th century, almost the entire city centre had fallen into disrepair. As society was changing,[clarification needed] politicians and other influential figures made plans to redesign large parts of it. There was an increasing demand for office buildings, and also for new roads, as the automobile became available to most people. A metro started operating in 1977 between the new suburb of Bijlmermeer in the city's Zuidoost (southeast) exclave and the centre of Amsterdam. Further plans were to build a new highway above the metro to connect Amsterdam Centraal and the city centre with other parts of the city. The required large-scale demolitions began in Amsterdam's former Jewish neighborhood. Smaller streets, such as the Jodenbreestraat and Weesperstraat, were widened and almost all houses and buildings were demolished. At the peak of the demolition, the Nieuwmarktrellen (Nieuwmarkt riots) broke out; the rioters expressed their fury about the demolition caused by the restructuring of the city. As a result, the demolition was stopped and the highway into the city's centre was never fully built; only the metro was completed. Only a few streets remained widened. The new city hall was built on the almost completely demolished Waterlooplein. Meanwhile, large private organizations, such as Stadsherstel Amsterdam, were founded to restore the entire city centre. Although the success of this struggle is visible today, efforts for further restoration are still ongoing. The entire city centre has reattained its former splendour and, as a whole, is now a protected area. Many of its buildings have become monuments, and in July 2010 the Grachtengordel (the three concentric canals: Herengracht, Keizersgracht, and Prinsengracht) was added to the UNESCO World Heritage List. In the 21st century, the Amsterdam city centre has attracted large numbers of tourists: between 2012 and 2015, the annual number of visitors rose from 10 to 17 million. Real estate prices have surged, and local shops are making way for tourist-oriented ones, making the centre unaffordable for the city's inhabitants. These developments have evoked comparisons with Venice, a city thought to be overwhelmed by the tourist influx. Construction of a new metro line connecting the part of the city north of the IJ to its southern part was started in 2003. The project was controversial because its cost had exceeded its budget by a factor of three by 2008, because of fears of damage to buildings in the centre, and because construction had to be halted and restarted multiple times. The new metro line was completed in 2018. Since 2014, renewed focus has been given to urban regeneration and renewal, especially in areas directly bordering the city centre, such as Frederik Hendrikbuurt. This urban renewal and expansion of the traditional centre of the city—with the construction of artificial islands of the new eastern IJburg neighbourhood—is part of the Structural Vision Amsterdam 2040 initiative. Geography Amsterdam is located in the Western Netherlands, in the province of North Holland, the capital of which is not Amsterdam, but rather Haarlem. The river Amstel ends in the city centre and connects to a large number of canals that eventually terminate in the IJ. Amsterdam's elevation is about −2 m (−6.6 ft) below sea level. The surrounding land is flat as it is formed of large polders. An artificial forest, Amsterdamse Bos, is in the southwest. Amsterdam is connected to the North Sea through the long North Sea Canal. Amsterdam is intensely urbanised, as is the Metropolitan Region Amsterdam surrounding the city. Comprising 219.4 km2 (84.7 sq mi) of land, the city proper has 4,457 inhabitants per km2 and 2,275 houses per km2. Parks and nature reserves make up 12% of Amsterdam's land area. Amsterdam has more than 100 km (60 mi) of canals, most of which are navigable by boat. The city's three main canals are the Prinsengracht, the Herengracht, and the Keizersgracht. In the Middle Ages, Amsterdam was surrounded by a moat, called the Singel, which now forms the innermost ring in the city, and gives the city centre a horseshoe shape. The city is also served by a seaport. It has been compared with Venice, due to its division into about 90 islands, which are linked by more than 1,200 bridges.[unreliable source?] Amsterdam has an oceanic climate (Köppen: Cfb) strongly influenced by its proximity to the North Sea to the west, with prevailing westerly winds. Amsterdam, as well as most of the North Holland province, lies in USDA Hardiness zone 8b. Frosts mainly occur during spells of easterly or northeasterly winds from the inner European continent. Even then, because Amsterdam is surrounded on three sides by large bodies of water, as well as having a significant heat-island effect, nights rarely fall below −5 °C (23 °F), while it could easily be −12 °C (10 °F) in Hilversum, 25 km (16 mi) southeast. Summers are moderately warm with several hot and humid days with occasional rain every month. The average daily high in August is 22.1 °C (72 °F), and 30 °C (86 °F) or higher is only measured on average on 2.5 days, placing Amsterdam in AHS Heat Zone 2. The record extremes range from −19.7 °C (−3.5 °F) to 36.3 °C (97.3 °F).[unreliable source?] Days with more than 1 mm (0.04 in) of precipitation are common, on average 133 days per year. Amsterdam's average annual precipitation is 838 mm (33 in). A large part of this precipitation falls as light rain or brief showers. Cloudy and damp days are common during the cooler months of October through March. Demographics In 1300, Amsterdam's population was around 1,000 people. While many towns in Holland experienced population decline during the 15th and 16th centuries, Amsterdam's population grew, mainly due to the rise of the profitable Baltic maritime trade especially in grain after the Burgundian victory in the Dutch–Hanseatic War in 1441. The population of Amsterdam was only modest compared to the towns and cities of Flanders and Brabant, which comprised the most urbanized area of the Low Countries. This changed when, during the Dutch Revolt, many people from the Southern Netherlands fled to the North, especially after Antwerp fell to Spanish forces in 1585. Jews from Spain, Portugal, and Eastern Europe similarly settled in Amsterdam, as did Germans and Scandinavians. In thirty years, Amsterdam's population more than doubled between 1585 and 1610. By 1600, its population was around 50,000. During the 1660s, Amsterdam's population reached 200,000. The city's growth levelled off and the population stabilized around 240,000 for most of the 18th century. In 1750, Amsterdam was the fourth largest city in Western Europe, behind London (676,000), Paris (560,000) and Naples (324,000). This was all the more remarkable as Amsterdam was neither the capital city nor the seat of government of the Dutch Republic, which itself was a much smaller state than Great Britain, France or the Ottoman Empire. In contrast to those other metropolises, Amsterdam was also surrounded by large towns such as Leiden (about 67,000), Rotterdam (45,000), Haarlem (38,000), and Utrecht (30,000). The city's population declined in the early 19th century, dipping under 200,000 in 1820. By the second half of the 19th century, industrialization spurred renewed growth. Amsterdam's population hit an all-time high of 872,000 in 1959, before declining in the following decades due to government-sponsored suburbanisation to so-called groeikernen (growth centres) such as Purmerend and Almere. Between 1970 and 1980, Amsterdam experienced a sharp population decline, peaking at a net loss of 25,000 people in 1973. By 1985 the city had only 675,570 residents. This was soon followed by reurbanization and gentrification, leading to renewed population growth in the 2010s. Also in the 2010s, much of Amsterdam's population growth was due to immigration to the city. In the 16th and 17th centuries, non-Dutch immigrants to Amsterdam were mostly Protestant Huguenots and Flemings, Sephardic Jews, and Westphalians. Huguenots came after the Edict of Fontainebleau in 1685, while the Flemish Protestants came during the Eighty Years' War against Catholic Spain. The Westphalians came to Amsterdam mostly for economic reasons; their influx continued through the 18th and 19th centuries. Before the Second World War, 10% of the city population was Jewish. Just twenty percent of them survived the Holocaust. Amsterdam experienced an influx of religions and cultures after the Second World War. With 180 different nationalities, Amsterdam is home to one of the widest varieties of nationalities of any city in the world. The proportion of the population of immigrant origin in the city proper is about 50% and 88% of the population are Dutch citizens. The first mass immigration in the 20th century was by people from Indonesia, who came to Amsterdam after the independence of the Dutch East Indies in the 1940s and 1950s. In the 1960s guest workers from Turkey, Morocco, Italy, and Spain immigrated to Amsterdam. After the independence of Suriname in 1975, a large wave of Surinamese settled in Amsterdam, mostly in the Bijlmer area. Other immigrants, including refugees asylum seekers and undocumented immigrants, came from Europe, the Americas, Asia, and Africa. In the 1970s and 1980s, many 'old' Amsterdammers moved to 'new' cities like Almere and Purmerend, prompted by the third Land-use planning bill of the Dutch Government. This bill promoted suburbanization and arranged for new developments in so-called "groeikernen", literally cores of growth. Young professionals and artists moved into neighborhoods De Pijp and the Jordaan abandoned by these Amsterdammers. The non-Western immigrants settled mostly in the social housing projects in Amsterdam-West and the Bijlmer. In 2006, people of non-Western origin made up approximately one-fifth of the population of Amsterdam, and more than 30% of the city's children. A slight majority of the residents of Amsterdam have at least one parent who was born outside the country. However, a much larger majority has at least one parent who was born inside the country (intercultural marriages are common in the city). Only a third of inhabitants under 15 are autochthons (person with two parents of Dutch origin). In 2023, autochthons were a minority in 40% of Amsterdam's neighborhoods. Segregation along ethnic lines is visible, with people of non-Western origin, considered a separate group by Statistics Netherlands, concentrating in specific neighborhoods especially in Nieuw-West, Zeeburg, Bijlmer and in certain areas of Amsterdam-Noord. In 2000, Christians formed the largest religious group in the city (28% of the population). The next largest religion was Islam (8%), most of whose followers were Sunni. By 2015, this remained largely unchanged, with a slight decrease in the Muslim population to 7.1%. Amsterdam has been one of the municipalities in the Netherlands that provided immigrants with extensive and free Dutch-language courses, which have benefited many immigrants. In 1578, the largely Catholic city of Amsterdam joined the revolt against Spanish rule, late in comparison to other major northern Dutch cities. Catholic priests were driven out of the city. Following the Dutch takeover, all churches were converted to Protestant worship. Calvinism was declared the main religion. It was forbidden to openly profess Roman Catholicism and the Catholic hierarchy was prohibited until the mid-19th century. This led to the establishment of clandestine churches, covert religious buildings hidden in pre-existing buildings. Catholics, some Jews, and dissenting Protestants worshipped in such buildings. A large influx of foreigners of many religions came to 17th-century Amsterdam, in particular Sephardic Jews from Spain and Portugal, Huguenots from France, Lutherans, Mennonites, as well as Protestants from across the Netherlands. This led to the establishment of many non-Dutch-speaking churches.[citation needed] In 1603, the Jewish received permission to practice their religion in the city. In 1639, the first synagogue was consecrated. The Jews came to call the town "Jerusalem of the West". As they became established in the city, other Christian denominations used converted Catholic chapels to conduct their own services. The oldest English-language church congregation in the world outside the United Kingdom is found at the Begijnhof. Regular services there are still offered in English under the auspices of the Church of Scotland. Being Calvinists, the Huguenots soon integrated into the Dutch Reformed Church, though often retaining their own congregations. Some, commonly referred to by the moniker 'Walloon', are recognizable today as they offer occasional services in French.[citation needed] In the second half of the 17th century, Amsterdam experienced an influx of Ashkenazim, Jews from Central and Eastern Europe. Jews often fled the pogroms in those areas. The first Ashkenazis who arrived in Amsterdam were refugees from the Khmelnytsky uprising occurring in Ukraine and the Thirty Years' War, which devastated much of Central Europe. They not only founded their own synagogues but had a strong influence on the 'Amsterdam dialect' adding a large Yiddish local vocabulary. Despite an absence of an official Jewish ghetto, most Jews preferred to live in the eastern part, which used to be the centre of medieval Amsterdam. The main street of this Jewish neighbourhood was Jodenbreestraat. The neighbourhood comprised the Waterlooplein and the Nieuwmarkt. Buildings in this neighbourhood fell into disrepair after the Second World War a large section of the neighbourhood was demolished during the construction of the metro system. This led to riots, and as a result, the original plans for large-scale reconstruction were abandoned by the government. The neighbourhood was rebuilt with smaller-scale residence buildings based on its original layout. Catholic churches in Amsterdam have been constructed since the restoration of the episcopal hierarchy in 1853. One of the principal architects behind the city's Catholic churches, Cuypers, was also responsible for the Amsterdam Centraal station and the Rijksmuseum. In 1924, the Catholic Church hosted the International Eucharistic Congress in Amsterdam; numerous Catholic prelates visited the city, where festivities were held in churches and stadiums. Catholic processions on the public streets, however, were still forbidden under law at the time. Only in the 20th century was Amsterdam's relation to Catholicism normalised, but despite its far larger population size, the episcopal see of the city was placed in the provincial town of Haarlem. Historically, Amsterdam has been predominantly Christian. In 1900 about 70% of the city’s population was Christian; the largest religious denomination was the Dutch Reformed Church, adhered to by about 45% of residents, while members of the Catholic Church formed 25%. In recent times, the city’s religious demography has diversified due to immigration from former colonies. Hinduism has been introduced by immigrants from Suriname and several distinct branches of Islam have been brought from various parts of the world. Islam is now the largest non-Christian religion in Amsterdam. The large community of Ghanaian immigrants has established African churches, often in parking garages in the Bijlmer area. Cityscape and architecture Amsterdam fans out south from the Amsterdam Centraal station and Damrak, the main street off the station. The oldest area of the town is known as De Wallen (English: "The Quays"). It lies to the east of Damrak and contains the city's famous red-light district. To the south of De Wallen is the old Jewish quarter of Waterlooplein. The medieval and colonial age canals of Amsterdam, known as grachten, embraces the heart of the city where homes have interesting gables. Beyond the Grachtengordel are the former working-class areas of Jordaan and de Pijp. The Museumplein with the city's major museums, the Vondelpark, a 19th-century park named after the Dutch writer Joost van den Vondel, as well as the Plantage neighbourhood, with the zoo, are also located outside the Grachtengordel. Several parts of the city and the surrounding urban area are polders. This can be recognised by the suffix -meer which means lake, as in Aalsmeer, Bijlmermeer, Haarlemmermeer and Watergraafsmeer. The Amsterdam canal system is the result of conscious city planning. In the early 17th century, when immigration was at a peak, a comprehensive plan was developed that was based on four concentric half-circles of canals with their ends emerging at the IJ bay. Known as the Grachtengordel, three of the canals were mostly for residential development: the Herengracht (where "Heren" refers to Heren Regeerders van de stad Amsterdam, ruling lords of Amsterdam, while gracht means canal, so that the name can be roughly translated as "Canal of the Lords"), Keizersgracht (Emperor's Canal) and Prinsengracht (Prince's Canal). The fourth and outermost canal is the Singelgracht, which is often not mentioned on maps because it is a collective name for all canals in the outer ring. The Singelgracht should not be confused with the oldest and innermost canal, the Singel. The canals served for defense, water management and transport. The defenses took the form of a moat and earthen dikes, with gates at transit points, but otherwise no masonry superstructures. The original plans have been lost, so historians, such as Ed Taverne, need to speculate on the original intentions: it is thought that the considerations of the layout were purely practical and defensive rather than ornamental. Construction started in 1613 and proceeded from west to east, across the breadth of the layout, like a gigantic windshield wiper as the historian Geert Mak calls it – and not from the centre outwards, as a popular myth has it. The canal construction in the southern sector was completed by 1656. Subsequently, the construction of residential buildings proceeded slowly. The eastern part of the concentric canal plan, covering the area between the Amstel River and the IJ Bay, has never been implemented. In the following centuries, the land was used for parks, senior citizens' homes, theatres, other public facilities, and waterways without much planning. Over the years, several canals have been filled in, becoming streets or squares, such as the Nieuwezijds Voorburgwal and the Spui. After the development of Amsterdam's canals in the 17th century, the city did not grow beyond its borders for two centuries. During the 19th century, Samuel Sarphati devised a plan based on the grandeur of Paris and London at that time. The plan envisaged the construction of new houses, public buildings, and streets just outside the Grachtengordel. The main aim of the plan, however, was to improve public health. Although the plan did not expand the city, it did produce some of the largest public buildings to date, like the Paleis voor Volksvlijt. Following Sarphati, civil engineers Jacobus van Niftrik and Jan Kalff designed an entire ring of 19th-century neighbourhoods surrounding the city's centre, with the city preserving the ownership of all land outside the 17th-century limit, thus firmly controlling development. Most of these neighbourhoods became home to the working class. In response to overcrowding, two plans were designed at the beginning of the 20th century which were very different from anything Amsterdam had ever seen before: Plan Zuid (designed by the architect Berlage) and West. These plans involved the development of new neighbourhoods consisting of housing blocks for all social classes. After the Second World War, large new neighbourhoods were built in the western, southeastern, and northern parts of the city. These new neighbourhoods were built to relieve the city's shortage of living space and give people affordable houses with modern conveniences. The neighbourhoods consisted mainly of large housing blocks located among green spaces, connected to wide roads, making the neighbourhoods accessible by motor car. The western suburbs which were built in that period are collectively called the Westelijke Tuinsteden. The area to the southeast of the city built during the same period is known as the Bijlmer. Amsterdam has a rich architectural history. The oldest building in Amsterdam is the Oude Kerk (English: Old Church), at the heart of the Wallen, consecrated in 1306. The oldest wooden building is Het Houten Huys at the Begijnhof. It was constructed around 1425 and is one of only two existing wooden buildings. It is also one of the few examples of Gothic architecture in Amsterdam. The oldest stone building in the Netherlands, The Moriaan is built in 's-Hertogenbosch. In the 16th century, wooden buildings were razed and replaced with brick ones. During this period, many buildings were constructed in the architectural style of the Renaissance. Buildings of this period are very recognisable with their stepped gable façades, which is the common Dutch Renaissance style. Amsterdam quickly developed its own Renaissance architecture. These buildings were built according to the principles of the architect Hendrick de Keyser. One of the most striking buildings designed by Hendrick de Keyser is the Westerkerk. In the 17th century baroque architecture became very popular, as it was elsewhere in Europe. This roughly coincided with Amsterdam's Golden Age. The leading architects of this style in Amsterdam were Jacob van Campen, Philips Vingboons and Daniel Stalpaert. Philip Vingboons designed splendid merchants' houses throughout the city. A famous building in baroque style in Amsterdam is the Royal Palace on Dam Square. Throughout the 18th century, Amsterdam was heavily influenced by French culture. This is reflected in the architecture of that period. Around 1815, architects broke with the baroque style and started building in different neo-styles. Most Gothic style buildings date from that era and are therefore said to be built in a neo-gothic style. At the end of the 19th century, the Jugendstil or Art Nouveau style became popular and many new buildings were constructed in this architectural style. Since Amsterdam expanded rapidly during this period, new buildings adjacent to the city centre were also built in this style. The houses in the vicinity of the Museum Square in Amsterdam Oud-Zuid are an example of Jugendstil. The last style that was popular in Amsterdam before the modern era was Art Deco. Amsterdam had its own version of the style, which was called the Amsterdamse School. Whole districts were built in this style, such as the Rivierenbuurt. A notable feature of the façades of buildings designed in Amsterdamse School is that they are highly decorated and ornate, with oddly shaped windows and doors. The old city centre is the focal point of all the architectural styles before the end of the 19th century. Jugendstil and Georgian are mostly found outside the city centre in the neighbourhoods built in the early 20th century, although there are also some striking examples of these styles in the city centre. Most historic buildings in the city centre and nearby are houses, such as the famous merchants' houses lining the canals. Amsterdam has many parks, open spaces, and squares throughout the city. The Vondelpark, the largest park in the city, is located in the Oud-Zuid neighbourhood and is named after the 17th-century Amsterdam author Joost van den Vondel. Yearly, the park has around 10 million visitors. In the park is an open-air theatre, a playground, and several horeca facilities. In the Zuid borough, is the Beatrixpark, named after Queen Beatrix. Between Amsterdam and Amstelveen is the Amsterdamse Bos ("Amsterdam Forest"), the largest recreational area in Amsterdam. Annually, almost 4.5 million people visit the park, which has a size of 1,000 hectares (2,500 acres) and is approximately three times the size of Central Park. The Amstelpark in the Zuid borough houses the Rieker windmill, which dates to 1636. Other parks include the Sarphatipark in the De Pijp neighbourhood, the Oosterpark in the Oost borough and the Westerpark in the Westerpark neighbourhood. The city has three beaches: Nemo Beach, Citybeach "Het stenen hoofd" (Silodam), and Blijburg, all located in the Centrum borough. The city has many open squares (plein in Dutch). The namesake of the city as the site of the original dam, Dam Square, is the main city square and has the Royal Palace and National Monument. Museumplein hosts various museums, including the Rijksmuseum, Van Gogh Museum, and Stedelijk Museum. Other squares include Rembrandtplein, Muntplein, Nieuwmarkt, Leidseplein, Spui and Waterlooplein. Economy Amsterdam is the financial and business capital of the Netherlands. According to the 2007 European Cities Monitor (ECM) – an annual location survey of Europe's leading companies carried out by global real estate consultant Cushman & Wakefield – Amsterdam is one of the top European cities in which to locate an international business, ranking fifth in the survey. with the survey determining London, Paris, Frankfurt and Barcelona as the four European cities surpassing Amsterdam in this regard. A substantial number of large corporations and banks' headquarters are located in the Amsterdam area, including: AkzoNobel, Heineken International, ING Group, ABN AMRO, TomTom, Delta Lloyd Group, Booking.com and Philips. Although many small offices remain along the historic canals, centrally based companies have increasingly relocated outside Amsterdam's city centre. Consequently, the Zuidas (English: South Axis) has become the new financial and legal hub of Amsterdam, with the country's five largest law firms and several subsidiaries of large consulting firms, such as Boston Consulting Group and Accenture, as well as the World Trade Centre (Amsterdam) located in the Zuidas district. In addition to the Zuidas, there are three smaller financial districts in Amsterdam: The adjoining municipality of Amstelveen is the location of KPMG International's global headquarters. Other non-Dutch companies have chosen to settle in communities surrounding Amsterdam since they allow freehold property ownership, whereas Amsterdam retains ground rent. The Amsterdam Stock Exchange (AEX), now part of Euronext, is the world's oldest stock exchange and, due to Brexit, has overtaken LSE as the largest bourse in Europe. It is near Dam Square in the city centre. The Port of Amsterdam is the fourth-largest port in Europe, the 38th largest port in the world, and the second-largest port in the Netherlands by metric tons of cargo. In 2014, the Port of Amsterdam had a cargo throughput of 97,4 million tons of cargo, which was mostly bulk cargo. Amsterdam has the biggest cruise port in the Netherlands with more than 150 cruise ships every year. In 2019, the new lock in IJmuiden opened; since then, the port has been able to grow to 125 million tonnes in capacity. Amsterdam is one of the most popular tourist destinations in Europe, receiving more than 5.34 million international visitors annually; this is excluding the 16 million day-trippers visiting the city every year. The number of visitors has been growing steadily over the past decade. This can be attributed to an increasing number of European visitors. Two-thirds of the hotels are located in the city's centre. Hotels with four or five stars contribute 42% of the total beds available and 41% of the overnight stays in Amsterdam. The room occupation rate was 85% in 2017, up from 78% in 2006. The majority of tourists (74%) originate from Europe. The largest group of non-European visitors come from the United States, accounting for 14% of the total. Certain years have a theme in Amsterdam to attract extra tourists. For example, the year 2006 was designated "Rembrandt 400", to celebrate the 400th birthday of Rembrandt van Rijn. Some hotels offer special arrangements or activities during these years. The average number of guests per year staying at the four campsites around the city ranges from 12,000 to 65,000. In 2023, the city began running a campaign to dissuade British men between the ages of 18 and 35 from coming to the city as tourists. The ad shows young men being handcuffed by police and is part of a new campaign to clean up the city's reputation. On 25 May 2023, in a bid to crackdown on wild tourist behaviour, the city banned weed smoking in public areas in and around the red light district. De Wallen, also known as Walletjes or Rosse Buurt, is a designated area for legalised prostitution and is Amsterdam's largest and best-known red-light district. This neighbourhood has become a famous attraction for tourists. It consists of a network of canals, streets, and alleys containing several hundred small, one-room apartments rented by sex workers who offer their services from behind a window or glass door, typically illuminated with red lights. In recent years, the city government has been closing and repurposing the famous red-light district windows to clean up the area and reduce the amount of party and sex tourism. Shops in Amsterdam range from large high-end department stores such as De Bijenkorf founded in 1870 to small specialty shops. Amsterdam's high-end shops are found in the streets P.C. Hooftstraat and Cornelis Schuytstraat, which are located in the vicinity of the Vondelpark. One of Amsterdam's busiest high streets is the narrow, medieval Kalverstraat in the heart of the city. Other shopping areas include the Negen Straatjes and Haarlemmerdijk and Haarlemmerstraat. Negen Straatjes are nine narrow streets within the Grachtengordel, the concentric canal system of Amsterdam. The Negen Straatjes differ from other shopping districts with the presence of a large diversity of privately owned shops. The Haarlemmerstraat and Haarlemmerdijk were voted the best shopping street in the Netherlands in 2011. These streets have as the Negen Straatjes a large diversity of privately owned shops. However, as the Negen Straatjes is dominated by fashion stores, the Haarlemmerstraat and Haarlemmerdijk offer a wide variety of stores, just to name some specialties: candy and other food-related stores, lingerie, sneakers, wedding clothing, interior shops, books, Italian deli's, racing and mountain bikes, skatewear, etc.[original research?] The city also features a large number of open-air markets such as the Albert Cuyp Market, Westerstraat-markt, Ten Katemarkt, and Dappermarkt. Some of these markets are held daily, like the Albert Cuypmarkt and the Dappermarkt. Others, like the Westerstraatmarkt, are held every week.[original research?] Several fashion brands and designers are based in Amsterdam. Fashion designers include Iris van Herpen, Mart Visser, Viktor & Rolf, Marlies Dekkers and Frans Molenaar. Fashion models like Yfke Sturm, Doutzen Kroes and Kim Noorda started their careers in Amsterdam. Amsterdam has its garment centre in the World Fashion Center. Fashion photographers Inez van Lamsweerde and Vinoodh Matadin were born in Amsterdam. Culture During the later part of the 16th century, Amsterdam's Rederijkerskamer (Chamber of rhetoric) organised contests between different Chambers in the reading of poetry and drama. In 1637, Schouwburg, the first theatre in Amsterdam was built, opening on 3 January 1638. The first ballet performances in the Netherlands were given in Schouwburg in 1642 with the Ballet of the Five Senses. In the 18th century, French theatre became popular. While Amsterdam was under the influence of German music in the 19th century there were few national opera productions; the Hollandse Opera of Amsterdam was built in 1888 for the specific purpose of promoting Dutch opera. In the 19th century, popular culture was centred on the Nes area in Amsterdam (mainly vaudeville and music-hall).[citation needed] An improved metronome was invented in 1812 by Dietrich Nikolaus Winkel. The Rijksmuseum (1885) and Stedelijk Museum (1895) were built and opened. In 1888, the Concertgebouworkest orchestra was established. With the 20th century came cinema, radio and television.[citation needed] Though most studios are located in Hilversum and Aalsmeer, Amsterdam's influence on programming is very strong. Many people who work in the television industry live in Amsterdam. Also, the headquarters of the Dutch SBS Broadcasting Group is located in Amsterdam. There are also a number of cultural centers based in the city that produce public programs about the arts, sciences, politics and history, including de Balie and the John Adams Institute. The most important museums of Amsterdam are located on the Museumplein (Museum Square), located at the southwestern side of the Rijksmuseum. It was created in the last quarter of the 19th century on the grounds of the former World's fair. The northeastern part of the square is bordered by the large Rijksmuseum. In front of the Rijksmuseum on the square itself is a long, rectangular pond. This is transformed into an ice rink in winter. The northwestern part of the square is bordered by the Van Gogh Museum, House of Bols Cocktail & Genever Experience and Coster Diamonds. The southwestern border of the Museum Square is the Van Baerlestraat, which is a major thoroughfare in this part of Amsterdam. The Concertgebouw is located across this street from the square. To the southeast of the square are several large houses, one of which contains the American consulate. A parking garage can be found underneath the square, as well as a supermarket. The Museumplein is covered almost entirely with a lawn, except for the northeastern part of the square which is covered with gravel. The current appearance of the square was realised in 1999 when the square was remodelled. The square itself is the most prominent site in Amsterdam for festivals and outdoor concerts, especially in the summer. Plans were made in 2008 to remodel the square again because many inhabitants of Amsterdam are not happy with its current appearance. The Rijksmuseum possesses the largest and most important collection of classical Dutch art. It opened in 1885. Its collection consists of nearly one million objects. The artist most associated with Amsterdam is Rembrandt, whose work, and the work of his pupils, is displayed in the Rijksmuseum. Rembrandt's masterpiece The Night Watch is one of the top pieces of art in the museum. It also houses paintings from artists like Bartholomeus van der Helst, Johannes Vermeer, Frans Hals, Ferdinand Bol, Albert Cuyp, Jacob van Ruisdael and Paulus Potter. Aside from paintings, the collection consists of a large variety of decorative art. This ranges from Delftware to giant doll-houses from the 17th century. The architect of the gothic revival building was P.J.H. Cuypers. The museum underwent a 10-year, 375 million euro renovation starting in 2003. The full collection was reopened to the public on 13 April 2013. The Rijksmuseum has remained the most visited museum in Amsterdam with 2.4 million visitors in 2024. Van Gogh lived in Amsterdam for a short while and there is a museum dedicated to his work. The museum is housed in one of the few modern buildings in this area of Amsterdam. The building was designed by Gerrit Rietveld. This building is where the permanent collection is displayed. A new building was added to the museum in 1999. This building, known as the performance wing, was designed by Japanese architect Kisho Kurokawa. Its purpose is to house temporary exhibitions of the museum. Some of Van Gogh's most famous paintings, like The Potato Eaters and Sunflowers, are in the collection. The Van Gogh museum is the second most visited museum in Amsterdam, not far behind the Rijksmuseum in terms of the number of visits, being approximately 1.8 million in 2024. Next to the Van Gogh Museum stands the Stedelijk Museum. This is Amsterdam's most important museum of modern art. The museum is as old as the square it borders and was opened in 1895. The permanent collection consists of works of art from artists like Piet Mondrian, Karel Appel, and Kazimir Malevich. After renovations lasting several years, the museum opened in September 2012 with a new composite extension that has been called 'The Bathtub' due to its resemblance to one. Amsterdam contains many other museums throughout the city. They range from small museums such as the Verzetsmuseum (Resistance Museum), KattenKabinet ("Cat Cabinet"), the Anne Frank House, and the Rembrandt House Museum, to the very large, like the Tropenmuseum (Museum of the Tropics), Amsterdam Museum (formerly known as Amsterdam Historical Museum), H'ART Museum and the Joods Historisch Museum (Jewish Historical Museum). The modern-styled Nemo is dedicated to child-friendly science exhibitions. Amsterdam's musical culture includes a large collection of songs that treat the city nostalgically and lovingly. The 1949 song "Aan de Amsterdamse grachten" ("On the canals of Amsterdam") was performed and recorded by many artists, including John Kraaijkamp Sr.; the best-known version is probably that by Wim Sonneveld (1962). In the 1950s Johnny Jordaan rose to fame with "Geef mij maar Amsterdam" ("I prefer Amsterdam"), which praises the city above all others (explicitly Paris); Jordaan sang especially about his own neighbourhood, the Jordaan ("Bij ons in de Jordaan"). Colleagues and contemporaries of Johnny include Tante Leen and Manke Nelis. Another notable Amsterdam song is "Amsterdam" by Jacques Brel (1964). A 2011 poll by Amsterdam newspaper Het Parool that Trio Bier's "Oude Wolf" was voted "Amsterdams lijflied". Notable Amsterdam bands from the modern era include the Osdorp Posse and the Ex. AFAS Live (formerly known as the Heineken Music Hall) is a concert hall located near the Johan Cruyff Arena (known as the Amsterdam Arena until 2018). Its main purpose is to serve as a podium for pop concerts for big audiences. Many famous international artists have performed there. Two other notable venues, Paradiso and the Melkweg are located near the Leidseplein. Both focus on broad programming, ranging from indie rock to hip-hop, R&B, and other popular genres. Other subcultural music venues are OCCII, OT301, De Nieuwe Anita, Winston Kingdom, and Zaal 100. Jazz has a strong following in Amsterdam, with the Bimhuis being the premier venue. In 2012, Ziggo Dome was opened, also near Amsterdam Arena, a state-of-the-art indoor music arena. AFAS Live is also host to many electronic dance music festivals, alongside many other venues. Armin van Buuren and Tiesto, some of the world's leading Trance DJs hail from the Netherlands and frequently perform in Amsterdam. Each year in October, the city hosts the Amsterdam Dance Event (ADE) which is one of the leading electronic music conferences and one of the biggest club festivals for electronic music in the world, attracting over 350,000 visitors each year. Another popular dance festival is 5daysoff, which takes place in the venues Paradiso and Melkweg. In the summertime, there are several big outdoor dance parties in or nearby Amsterdam, such as Awakenings, Dance Valley, Mystery Land, Loveland, A Day at the Park, Welcome to the Future, and Valtifest. Amsterdam has a world-class symphony orchestra, the Royal Concertgebouw Orchestra. Their home is the Concertgebouw, which is across the Van Baerlestraat from the Museum Square. It is considered by critics to be a concert hall with some of the best acoustics in the world. The building contains three halls, Grote Zaal, Kleine Zaal, and Spiegelzaal. Some nine hundred concerts and other events per year take place in the Concertgebouw, for a public of over 700,000, making it one of the most-visited concert halls in the world. The opera house of Amsterdam is located adjacent to the city hall. Therefore, the two buildings combined are often called the Stopera, (a word originally coined by protesters against its very construction: Stop the Opera[-house]). This huge modern complex, opened in 1986, lies in the former Jewish neighbourhood at Waterlooplein next to the river Amstel. The Stopera is the home base of Dutch National Opera, Dutch National Ballet and the Holland Symfonia. Muziekgebouw aan 't IJ is a concert hall, which is located in the IJ near the central station. Its concerts perform mostly modern classical music. Located adjacent to it, is the Bimhuis, a concert hall for improvised and jazz music. Amsterdam has three main theatre buildings. The Stadsschouwburg at the Leidseplein is the home base of Toneelgroep Amsterdam. The current building dates from 1894. Most plays are performed in the Grote Zaal (Great Hall). The normal program of events encompasses all sorts of theatrical forms. In 2009, the new hall of the Stadsschouwburg Amsterdam, Toneelgroep Amsterdam, and Melkweg opened, and the renovation of the front end of the theatre was ready. The Dutch National Opera and Ballet (formerly known as Het Muziektheater), dating from 1986, is the principal opera house and home to Dutch National Opera and Dutch National Ballet. Royal Theatre Carré was built as a permanent circus theatre in 1887 and is currently mainly used for musicals, cabaret performances, and pop concerts. The recently re-opened DeLaMar Theater houses more commercial plays and musicals. A new theatre has also moved into the Amsterdam scene in 2014, joining other established venues: Theater Amsterdam is located in the west part of Amsterdam, on the Danzigerkade. It is housed in a modern building with a panoramic view over the harbour. The theatre is the first-ever purpose-built venue to showcase a single play entitled ANNE, the play based on Anne Frank's life. On the east side of town, there is a small theatre in a converted bathhouse, the Badhuistheater. The theatre often has English programming. The Netherlands has a tradition of cabaret or kleinkunst, which combines music, storytelling, commentary, theatre, and comedy. Cabaret dates back to the 1930s and artists like Wim Kan, Wim Sonneveld, and Toon Hermans were pioneers of this form of art in the Netherlands. In Amsterdam are the Kleinkunstacademie (English: Cabaret Academy) and Nederlied Kleinkunstkoor (English: Cabaret Choir). Contemporary popular artists are Youp van 't Hek, Freek de Jonge, Herman Finkers, Hans Teeuwen, Theo Maassen, Herman van Veen, Najib Amhali, Raoul Heertje, Jörgen Raymann, Brigitte Kaandorp and Comedytrain. The English-spoken comedy scene was established with the founding of Boom Chicago in 1993. They have their own theatre at Leidseplein. Amsterdam is famous for its vibrant and diverse nightlife. Amsterdam has many cafés (bars). They range from large and modern to small and cosy. The typical Bruine Kroeg (brown café) breathes a more old-fashioned atmosphere with dimmed lights, candles, and somewhat older clientele. These brown cafés mostly offer a wide range of local and international artisanal beers. Most cafés have terraces in summertime. A common sight on the Leidseplein during summer is a square full of terraces packed with people drinking beer or wine. Many restaurants can be found in Amsterdam as well. Since Amsterdam is a multicultural city, a lot of different ethnic restaurants can be found. Restaurants range from being rather luxurious and expensive to being ordinary and affordable. Amsterdam also possesses many discothèques. The two main nightlife areas for tourists are the Leidseplein and the Rembrandtplein. The Paradiso, Melkweg and Sugar Factory are cultural centres, which turn into discothèques on some nights. In 2008, there were 140 festivals and events in Amsterdam. During the same year, Amsterdam was designated as the World Book Capital for one year by UNESCO. Famous festivals and events in Amsterdam include: Koningsdag (which was named Koninginnedag until the crowning of King Willem-Alexander in 2013) (King's Day – Queen's Day); the Holland Festival for the performing arts; the yearly Prinsengrachtconcert (classical concerto on the Prinsen canal) in August; the 'Stille Omgang' (a silent Roman Catholic evening procession held every March); Amsterdam Gay Pride; The Cannabis Cup; and the Uitmarkt. On Koningsdag—which is held each year on 27 April—hundreds of thousands of people travel to Amsterdam to celebrate with the city's residents. The entire city becomes overcrowded with people buying products from the free market, or visiting one of the many music concerts. The yearly Holland Festival attracts international artists and visitors from all over Europe. Amsterdam Gay Pride is a yearly local LGBT parade of boats in Amsterdam's canals, held on the first Saturday in August. The annual Uitmarkt is a three-day cultural event at the start of the cultural season in late August. It offers previews of many different artists, such as musicians and poets, who perform on podia. Sports Amsterdam is home of the Eredivisie football club AFC Ajax. The stadium Johan Cruyff Arena is the home of Ajax. It is located in the south-east of the city next to the new Amsterdam Bijlmer ArenA railway station. Before moving to their current location in 1996, Ajax played their regular matches in the now demolished De Meer Stadion in the eastern part of the city or in the Olympic Stadium. In 1928, Amsterdam hosted the Summer Olympics. The Olympic Stadium built for the occasion has been completely restored and is now used for cultural and sporting events, such as the Amsterdam Marathon. In 1920, Amsterdam assisted in hosting some of the sailing events for the Summer Olympics held in neighbouring Antwerp, Belgium by hosting events at Buiten IJ. They had also made a bid to host the 1952 and 1992 Summer Olympics but lost to Helsinki and Barcelona. The city holds the Dam to Dam Run, a 16 km (10 mi) race from Amsterdam to Zaandam, as well as the Amsterdam Marathon. The ice hockey team Amstel Tijgers plays in the Jaap Eden ice rink. The team competes in the Dutch Ice Hockey Premier League. Speed skating championships have been held on the 400-meter lane of this ice rink. Amsterdam holds two American football franchises: the Amsterdam Crusaders and the Amsterdam Panthers. The Amsterdam Pirates baseball team competes in the Dutch Major League. There are three field hockey teams: Amsterdam, Pinoké, and Hurley, who play their matches around the Wagener Stadium in the nearby city of Amstelveen. The basketball team MyGuide Amsterdam competes in the Dutch premier division and play their games in the Sporthallen Zuid. There is one rugby club in Amsterdam, which also hosts sports training classes such as RTC (Rugby Talenten Centrum or Rugby Talent Centre) and the National Rugby Stadium. Since 1999, the city of Amsterdam honours the best sportsmen and women at the Amsterdam Sports Awards. Boxer Raymond Joval and field hockey midfielder Carole Thate were the first to receive the awards, in 1999. Amsterdam hosted the World Gymnaestrada in 1991 and will do so again in 2023. Politics The city of Amsterdam is a municipality under the Dutch Municipalities Act. It is governed by a directly elected municipal council, a municipal executive, and a mayor. Since 1981, the municipality of Amsterdam has gradually been divided into semi-autonomous boroughs, called stadsdelen or 'districts'. Over time, a total of 15 boroughs were created. In May 2010, under a major reform, the number of Amsterdam boroughs was reduced to eight: Amsterdam-Centrum covering the city centre including the canal belt, Amsterdam-Noord consisting of the neighbourhoods north of the IJ lake, Amsterdam-Oost in the east, Amsterdam-Zuid in the south, Amsterdam-West in the west, Amsterdam Nieuw-West in the far west, Amsterdam Zuidoost in the southeast, and Westpoort covering the Port of Amsterdam area. As with all Dutch municipalities, Amsterdam is governed by a directly elected municipal council, a municipal executive and a government appointed mayor (burgemeester). The mayor is a member of the municipal executive board but also has individual responsibilities in maintaining public order. On 27 June 2018, Femke Halsema (former member of House of Representatives for GroenLinks from 1998 to 2011) was appointed as the first woman to be Mayor of Amsterdam by the King's Commissioner of North Holland for a six-year term after being nominated by the Amsterdam municipal council and began serving a six-year term on 12 July 2018. She replaces Eberhard van der Laan (Labour Party) who was the Mayor of Amsterdam from 2010 until his death in October 2017. After the 2014 municipal council elections, a governing majority of D66, VVD and SP was formed – the first coalition without the Labour Party since World War II. Next to the Mayor, the municipal executive consists of eight wethouders ('alderpersons') appointed by the municipal council: four D66 alderpersons, two VVD alderpersons and two SP alderpersons. On 18 September 2017, it was announced by Eberhard van der Laan in an open letter to Amsterdam citizens that Kajsa Ollongren would take up his office as acting Mayor of Amsterdam with immediate effect due to ill health. Ollongren was succeeded as acting Mayor by Eric van der Burg on 26 October 2017 and by Jozias van Aartsen on 4 December 2017. Unlike most other Dutch municipalities, Amsterdam is subdivided into seven boroughs, called stadsdelen or 'districts', and the urban area of Weesp. This system was gradually implemented in the 1980s to improve local governance. The boroughs are responsible for many activities that had previously been run by the central city. In 2010, the number of Amsterdam boroughs reached fifteen. Fourteen of those had their own district council (deelraad), elected by a popular vote. The fifteenth, Westpoort, covers the harbour of Amsterdam and has very few residents. Therefore, it was governed by the central municipal council. Under the borough system, municipal decisions are made at the borough level, except for those affairs on the whole city such as major infrastructure projects, which are the jurisdiction of the central municipal authorities. In 2010, the borough system was restructured, in which many smaller boroughs merged into larger boroughs. In 2014, under a reform of the Dutch Municipalities Act, the Amsterdam boroughs lost much of their autonomous status, as their district councils were abolished. The municipal council of Amsterdam voted to maintain the borough system by replacing the district councils with smaller, but still directly elected district committees (bestuurscommissies). Under a municipal ordinance, the new district committees were granted responsibilities through the delegation of regulatory and executive powers by the central municipal council. "Amsterdam" is usually understood to refer to the municipality of Amsterdam. Colloquially, some areas within the municipality, such as the town of Durgerdam, may not be considered part of Amsterdam. Statistics Netherlands uses three other definitions of Amsterdam: metropolitan agglomeration Amsterdam (Grootstedelijke Agglomeratie Amsterdam, not to be confused with Grootstedelijk Gebied Amsterdam, a synonym of Groot Amsterdam), Greater Amsterdam (Groot Amsterdam, a COROP region) and the urban region Amsterdam (Stadsgewest Amsterdam). The Amsterdam Department for Research and Statistics uses a fourth conurbation, namely the Stadsregio Amsterdam ('City Region of Amsterdam'). The city region is similar to Greater Amsterdam but includes the municipalities of Zaanstad and Wormerland. The smallest of these areas is the municipality of Amsterdam with a population of about 870,000 in 2021. The larger conurbation had a population of over one million. It includes the municipalities of Zaanstad, Wormerland, Oostzaan, Diemen, and Amstelveen only, as well as the municipality of Amsterdam. Greater Amsterdam includes 15 municipalities and had a population of 1,400,000 in 2021. Though much larger in area, the population of this area is only slightly larger, because the definition excludes the relatively populous municipality of Zaanstad. The largest area by population, the Metropolitan Region Amsterdam (Dutch: Metropoolregio Amsterdam), has a population of 2,33 million. It includes for instance Zaanstad, Wormerland, Muiden, Abcoude, Haarlem, Almere and Lelystad but excludes Graft-De Rijp. Amsterdam is part of the conglomerate metropolitan area Randstad, with a total population of 6,659,300 inhabitants. Of these various metropolitan area configurations, only the Stadsregio Amsterdam (City Region of Amsterdam) has a formal governmental status. Its responsibilities include regional spatial planning and metropolitan public transport concessions. Under the Dutch Constitution, Amsterdam is the capital of the Netherlands. Since the 1983 constitutional revision, the constitution mentions "Amsterdam" and "capital" in chapter 2, article 32: The king's confirmation by oath and his coronation take place in "the capital Amsterdam" ("de hoofdstad Amsterdam"). Previous versions of the constitution only mentioned "the city of Amsterdam" ("de stad Amsterdam"). For a royal investiture, therefore, the States General of the Netherlands (the Dutch Parliament) meets for a ceremonial joint session in Amsterdam. The ceremony traditionally takes place at the Nieuwe Kerk on Dam Square, immediately after the former monarch has signed the act of abdication at the nearby Royal Palace of Amsterdam. Normally, however, the Parliament sits in The Hague, the city which has historically been the seat of the Dutch government, the Dutch monarchy, and the Dutch supreme court. Foreign embassies are also located in The Hague. The coat of arms of Amsterdam is composed of several historical elements. First and centre are three St Andrew's crosses, aligned in a vertical band on the city's shield (although Amsterdam's patron saint was Saint Nicholas). These St Andrew's crosses can also be found on the city shields of neighbours Amstelveen and Ouder-Amstel. This part of the coat of arms is the basis of the flag of Amsterdam, flown by the city government, but also as civil ensign for ships registered in Amsterdam. Second is the Imperial Crown of Austria. In 1489, out of gratitude for services and loans, Maximilian I awarded Amsterdam the right to adorn its coat of arms with the king's crown. Then, in 1508, this was replaced with Maximilian's imperial crown when he was crowned Holy Roman Emperor. In the early years of the 17th century, Maximilian's crown in Amsterdam's coat of arms was again replaced, this time with the crown of Emperor Rudolph II, a crown that became the Imperial Crown of Austria. The lions date from the late 16th century, when the city and province became part of the Republic of the Seven United Netherlands. Last came the city's official motto: Heldhaftig, Vastberaden, Barmhartig ("Heroic, Determined, Merciful"), bestowed on the city in 1947 by Queen Wilhelmina, in recognition of the city's bravery during the Second World War. Transport Currently, there are sixteen tram routes and five metro routes. All are operated by the municipal public transport operator Gemeentelijk Vervoerbedrijf (GVB), which also runs the city bus network. Four fare-free GVB ferries carry pedestrians and cyclists across the IJ lake to the borough of Amsterdam-Noord, and two fare-charging ferries run east and west along the harbour. There are also privately operated water taxis, a water bus, a boat-sharing operation, electric rental boats, and canal cruises, that transport people along Amsterdam's waterways. Regional buses, and some suburban buses, are operated by Connexxion and EBS. International coach services are provided by FlixBus and BlaBlaCar Bus. To facilitate easier transport to the centre of Amsterdam, the city has various P+R Locations where people can park their car at an affordable price and transfer to one of the numerous public transport lines. Amsterdam was intended in 1932 to be the hub, a kind of Kilometre Zero, of the highway system of the Netherlands, with freeways numbered One to Eight planned to originate from the city. The outbreak of the Second World War and shifting priorities led to the current situation, where only roads A1, A2, and A4 originate from Amsterdam according to the original plan. The A3 to Rotterdam was cancelled in 1970 to conserve the Groene Hart. Road A8, leading north to Zaandam and the A10 Ringroad were opened between 1968 and 1974. Besides the A1, A2, A4 and A8, several freeways, such as the A7 and A6, carry traffic mainly bound for Amsterdam. The A10 ringroad surrounding the city connects Amsterdam with the Dutch national network of freeways. Interchanges on the A10 allow cars to enter the city by transferring to one of the 18 city roads, numbered S101 through to S118. These city roads are regional roads without grade separation, and sometimes without a central reservation. Most are accessible by cyclists. The S100 Centrumring is a smaller ring road circumnavigating the city's centre. In the city centre, driving a car is discouraged. Parking fees are expensive, and many streets are closed to cars or are one-way. The local government sponsors carsharing and carpooling initiatives such as Autodelen and Meerijden.nu. The local government has also started removing parking spaces in the city in 2019, with the goal of removing 10,000 spaces (roughly 1,500 per year) by 2025. Amsterdam is served by ten stations of the Nederlandse Spoorwegen (Dutch Railways). Five are intercity stops: Sloterdijk, Zuid, Amstel, Bijlmer ArenA and Amsterdam Centraal. The stations for local services are: Lelylaan, RAI, Holendrecht, Muiderpoort and Science Park. Amsterdam Centraal is also an international railway station. From the station, there are regular services to destinations such as Austria, Belgium, Czech Republic, France, Germany, Switzerland and the United Kingdom. Among these trains are international trains of the Nederlandse Spoorwegen and Deutsche Bahn to Berlin, Eurostar services to Antwerp, Brussels, Paris and London and ICE services to Cologne and Frankfurt. Amsterdam Airport Schiphol is less than 20 minutes by train from Amsterdam Centraal station and is served by domestic and international intercity trains, such as Eurostar and EuroCity. Schiphol is the largest airport in the Netherlands, the third-largest in Europe, and the 14th-largest in the world in terms of passengers. It handles over 68 million passengers per year and is the home base of four airlines, KLM, Transavia, Martinair and Arkefly. As of 2014[update], Schiphol was the fifth busiest airport in the world measured by international passenger numbers. This airport is 4 meters below sea level. Although Schiphol is internationally known as Amsterdam Schiphol Airport it lies in the neighbouring municipality of Haarlemmermeer, southwest of the city. Rotterdam The Hague Airport, a smaller international airport, is also within an hour's drive of the city. Amsterdam is one of the most bicycle-friendly large cities in the world and is a centre of bicycle culture with good facilities for cyclists such as bike paths and bike racks, and several guarded bike storage garages (fietsenstalling) which can be used. According to the most recent figures published by the Central Bureau of Statistics (CBS), in 2015 the 442,693 households (850,000 residents) in Amsterdam together owned 847,000 bicycles – 1.91 bicycles per household. Theft is widespread—in 2011, about 83,000 bicycles were stolen in Amsterdam. Bicycles are used by all socio-economic groups because of their convenience, Amsterdam's small size, the 400 km (249 mi) of bike paths, the flat terrain, and the inconvenience of driving an automobile. Education Amsterdam has two universities: the University of Amsterdam (Universiteit van Amsterdam, UvA), and the Vrije Universiteit Amsterdam (VU). The University of Amsterdam is home to Room for Discussion, an independent interview platform that has welcomed a variety of prominent guests including Christine Lagarde, Mario Draghi, Charles Michel, Rob Bauer, and Sviatlana Tsikhanouskaya. Other institutions for higher education include an art school – Gerrit Rietveld Academie, a university of applied sciences – the Hogeschool van Amsterdam, and the Amsterdamse Hogeschool voor de Kunsten. Amsterdam's International Institute of Social History is one of the world's largest documentary and research institutions concerning social history, and especially the history of the labour movement. Amsterdam's Hortus Botanicus, founded in the early 17th century, is one of the oldest botanical gardens in the world, with many old and rare specimens, among them the coffee plant that served as the parent for the entire coffee culture in Central and South America. There are over 200 primary schools in Amsterdam. Some of these primary schools base their teachings on particular pedagogic theories like the various Montessori schools. The biggest Montessori high school in Amsterdam is the Montessori Lyceum Amsterdam. Many schools, however, are based on religion. This used to be primarily Roman Catholicism and various Protestant denominations, but with the influx of Muslim immigrants, there has been a rise in the number of Islamic schools. Jewish schools can be found in the southern suburbs of Amsterdam. Amsterdam is noted for having five independent grammar schools (Dutch: gymnasia), the Vossius Gymnasium, Barlaeus Gymnasium, St. Ignatius Gymnasium, Het 4e Gymnasium and the Cygnus Gymnasium where a classical curriculum including Latin and classical Greek is taught. Though believed until recently by many to be an anachronistic and elitist concept that would soon die out, the gymnasia have recently experienced a revival, leading to the formation of a fourth and fifth grammar school in which the three aforementioned schools participate. Most secondary schools in Amsterdam offer a variety of different levels of education in the same school. The city also has various colleges ranging from art and design to politics and economics which are mostly also available for students coming from other countries. Schools for foreign nationals in Amsterdam include the Amsterdam International Community School, British School of Amsterdam, Albert Einstein International School Amsterdam, Lycée Vincent van Gogh La Haye-Amsterdam primary campus (French school), International School of Amsterdam, and the Japanese School of Amsterdam. Notable people Media Amsterdam is a prominent centre for national and international media. Some locally based newspapers include Het Parool, a national daily paper; De Telegraaf, the largest Dutch daily newspaper; the daily newspapers Trouw, de Volkskrant and NRC; De Groene Amsterdammer, a weekly newspaper; the free newspapers Metro and The Holland Times (printed in English). Amsterdam is home to the second-largest Dutch commercial TV group SBS Broadcasting Group, consisting of TV stations SBS6, Net5, and Veronica. However, Amsterdam is not considered 'the media city of the Netherlands'. The town of Hilversum, 30 km (19 mi) south-east of Amsterdam, has been crowned with this unofficial title. Hilversum is the principal centre for radio and television broadcasting in the Netherlands. Radio Netherlands, heard worldwide via shortwave radio since the 1920s, is also based there. Hilversum is home to an extensive complex of audio and television studios belonging to the national broadcast production company NOS, as well as to the studios and offices of all the Dutch public broadcasting organisations and many commercial TV production companies. In 2012, the music video for "Live My Life" by Far East Movement was filmed in various parts of Amsterdam. Several movies have been filmed in Amsterdam, including the James Bond film Diamonds Are Forever, Ocean's Twelve, Girl with a Pearl Earring, Kidnapping Mr. Heineken, Layer Cake and The Hitman's Bodyguard. Amsterdam is also featured in John Green's book The Fault in Our Stars, which was made into a film that also partly takes place in Amsterdam. Amsterdam appears as a multiplayer map in Modern Warfare II under the name Breenbergh Hotel. Amsterdam also appears in Black Ops Cold War in an update, having players fight through the city. Housing From the late 1960s onwards many buildings in Amsterdam have been squatted both for housing and for use as social centres. A number of these squats have legalised and become well known, such as OCCII, OT301, Paradiso and Vrankrijk. Sister cities See also Notes References Further reading External links |

Contents Solomon's Temple Solomon's Temple, also known as the First Temple (Hebrew: בַּיִת רִאשׁוֹן, romanized: Bayyit Rīšōn, lit. 'First Temple'), was a biblical Temple in Jerusalem believed to have existed between the 10th and 6th centuries BCE. Its description is largely based on narratives in the Hebrew Bible, in which it was commissioned by biblical king Solomon before being destroyed during the Siege of Jerusalem by Nebuchadnezzar II of the Neo-Babylonian Empire in 587 BCE. No excavations are allowed on the Temple Mount, and no positively identified remains of the destroyed temple have been found. Most modern scholars agree that the First Temple existed on the Temple Mount in Jerusalem by the time of the Babylonian siege, and there is significant debate among scholars over the date of its construction and the identity of its builder. The Hebrew Bible, specifically within the Book of Kings, includes a detailed narrative about the construction's ordering by Solomon, the penultimate ruler of the United Kingdom of Israel. It further credits Solomon as the placer of the Ark of the Covenant in the Holy of Holies, a windowless inner sanctum within the structure. Entry into the Holy of Holies was heavily restricted; the High Priest of Israel was the only authority permitted to enter the sanctuary, and only did so on Yom Kippur, carrying the blood of a sacrificial lamb and burning incense. In addition to serving as a religious building for worship, the First Temple also functioned as a place of assembly for the Israelites. The First Temple's destruction and the subsequent Babylonian captivity were both events that were seen as a fulfillment of biblical prophecies and thus affected Judaic religious beliefs, precipitating the Israelites' transition from either polytheism or monolatrism (as seen in Yahwism) to firm Jewish monotheism.[original research?] Previously, many scholars accepted the biblical narrative of the First Temple's construction by Solomon as authentic. During the 1980s, skeptical approaches to the biblical text as well as the archaeological record led some scholars to doubt whether there was any Temple in Jerusalem constructed as early as the 10th century BCE. Some scholars have suggested that the original structure built by Solomon was relatively modest, and was later rebuilt on a larger scale. No direct evidence for the existence of Solomon's Temple has been found. Due to the extreme religious and political sensitivity of the site, no recent archaeological excavations have been conducted on the Temple Mount. Nineteenth and early-twentieth-century excavations around the Temple Mount did not identify "even a trace" of the complex. Two 21st-century findings from the Israelite period in present-day Israel bear resemblance to Solomon's Temple as it is described in the Hebrew Bible: a shrine model from the early half of the 10th century BCE in Khirbet Qeiyafa; and the Tel Motza temple, dated to the 9th century BCE and located in the neighbourhood of Motza within West Jerusalem. The biblical description of Solomon's Temple also appears to share similarities with several Syro-Hittite temples of the same period discovered in modern-day Syria and Turkey, such as those in Ain Dara and Tell Tayinat. Following Jewish return from exile, Solomon's Temple was replaced with the Second Temple. Location Archeologist Israel Finkelstein writes that the exact location of the Temple is unknown. It is believed to have been situated upon the hill that forms the site of the Second Temple and present-day Temple Mount, where the Dome of the Rock is situated. According to the Bible, Solomon's Temple was built on Mount Moriah in Jerusalem, where an angel of God had appeared to David (2 Chronicles 3:1). The site was originally a threshing floor David had purchased from Araunah the Jebusite (2 Samuel 24:18–25; 2 Chronicles 3:1). Schmid and Rupprecht are of the view that the site of the temple used to be a Jebusite shrine that Solomon chose in an attempt to unify the Jebusites and Israelites. Biblical narrative According to 1 Kings, the foundation of the Temple is laid in Ziv, the second month of the fourth year of Solomon's reign and construction is completed in Bul, the eighth month of Solomon's eleventh year, thus taking about seven years. The Hebrew Bible says that the Tyrians played a leading role in the construction of the Temple. The Second Book of Samuel mentions how David and Hiram forged an alliance. This friendship continues after Solomon succeeds David, and the two refer to each other as brothers. A literary account of how Hiram helps Solomon build the Temple is given in 1 Kings (chapters 5–9) and 2 Chronicles (chapters 2–7). Hiram agrees to Solomon's request to supply him with cedar and cypress trees for the construction of the Temple. He tells Solomon that he will send the trees by sea: "I will make them into rafts to go by the sea to the place that you indicate. I will have them broken up there for you to take away." In return for the lumber, Solomon sends him wheat and oil. Solomon also brings over a skilled craftsman from Tyre, also called Hiram (or Huram-abi), who oversees the construction of the Temple. Stonemasons from Gebal (Byblos) cut stones for the Temple. After the Temple and palace (taking an additional 13 years) is completed, Solomon hands over twenty cities in the northwestern Galilee near Tyre as a repayment to Hiram. Hiram was not pleased with the gift, however, and asks "what are these towns that you have given me, my brother?". Hiram then calls them "the land of Cabul", and the writer of 1 Kings 9 says they were called by this name "to this day". Hiram however remains on friendly terms with Solomon. The Second Book of Chronicles fills in some details of the construction not given in narrative brought in 1 Kings. It states that the trees sent as rafts were sent to the city of Joppa on the Mediterranean coast, and in return for the lumber supplied, Solomon, in addition to the wheat and oil, sent wine to Hiram. According to biblical narrative, the purpose of Solomon’s Temple was to store the Ark of the Covenant. 1 Kings 8:1–9 and 2 Chronicles 5:2–10 record that in the seventh month of the year, at the feast of Tabernacles, the priests and the Levites brought the Ark of the Covenant from the City of David. Within the temple, the Ark was placed inside the Holy of Holies. 1 Kings 8:10–66 and 2 Chronicles 6:1–42 recount the events of the temple's dedication. When the priests emerged from the holy of holies after placing the Ark there, the Temple was filled with an overpowering cloud that interrupted the dedication ceremony, "for the glory of the Lord had filled the house of the Lord [such that] the priests could not stand to minister" (1 Kings 8:10–11; 2 Chronicles 5:13, 14). Solomon interpreted the cloud as "[proof] that his pious work was accepted": "The Lord has said that he would dwell in thick darkness. I have built you an exalted house, a place for you to dwell in forever." — 1 Kings 8:12–13 The allusion is to Leviticus 16:2: The Lord said to Moses: Tell your brother Aaron not to come just at any time into the sanctuary inside the curtain before the mercy seat that is upon the ark, or he will die; for I appear in the cloud upon the mercy seat. The Pulpit Commentary notes that "Solomon had thus every warrant for connecting a theophany with the thick dark cloud". Solomon then led the whole assembly of Israel in prayer, noting that the construction of the temple represented a fulfilment of God's promise to David, dedicating the temple as a place of prayer and reconciliation for the people of Israel and for foreigners living in Israel, and highlighting the paradox that God who lives in the heavens cannot really be contained within a single building. The dedication was concluded with musical celebration and sacrifices said to have included "twenty-two thousand bulls and one hundred and twenty thousand sheep". These sacrifices were offered outside the temple, in "the middle of the court that was in front of the house of the Lord", because the altar inside the temple, despite its extensive dimensions, was not big enough for the offerings being made that day. The celebration lasted eight days and was attended by "very great assembly [gathered] from the entrance of Hamath to the Brook of Egypt". The subsequent feast of Tabernacles extended the whole celebration to 14 days, before the people were "sent away to their homes". After the dedication, Solomon hears in a dream that God has heard his prayer, and God will continue to hear the prayers of the people of Israel if they adopt the four ways in which they could move God to action: humility, prayer, seeking his face, and turning from wicked ways. Conversely, if they turn aside and forsake God's commandments and worship other gods, then God will abandon the temple: "this house which I have sanctified for My name I will cast out of My sight". According to the biblical narrative, Solomon's Temple was plundered several times. In the fifth year of Rehoboam's reign (commonly dated to 926 BCE), Egyptian pharaoh Shishak (positively identified with Shoshenq I) took away treasures of the Temple and the king's house, as well as shields of gold that Solomon had made; Rehoboam replaced them with brass ones (1 Kings 14:25; 2 Chronicles 12:1–12). A century later, Jehoash, king of the northern Kingdom of Israel, advanced on Jerusalem, broke down a portion of the wall, and carried away the treasures of the Temple and the palace (2 Kings 14:13–14). Later, when Ahaz of Judah was threatened by defeat at the hands of Rezin of Aram-Damascus and Pekah of Israel, he turned to king Tiglath-Pileser IV for help. To persuade him, he "took the silver and gold that was found in the house of Yahweh, and in the treasures of the king's house, and sent it for a present to the King of Assyria" (2 Kings 16:8). At another critical juncture, Hezekiah cut off the gold from the doors and doorsteps of the temple he himself had overlaid, and gave it to king Sennacherib (2 Kings 18:15–16). 2 Kings 12:1–17 and 2 Chronicles 24:1–14 recount that King Joash and the priests of the temple organised a restoration programme funded from popular donations. The temple was restored to its original condition and further reinforced. According to the Bible, the Temple was plundered by King Nebuchadnezzar II of the Neo-Babylonian Empire when the Babylonians attacked Jerusalem during the brief reign of Jehoiachin c. 598 BCE (2 Kings 24:13). A decade later, Nebuchadnezzar again besieged Jerusalem and after 30 months finally breached the city walls in 587/6 BCE. The city finally fell to his army in July 586/5 BCE. A month later, Nebuzaradan, commander of Nebuchadnezzar's guard, was sent to burn and demolish the city. According to the Bible, "he set fire to the Temple of Yahweh, the royal palace and all the houses of Jerusalem" (2 Kings 25:9). Everything worth plundering was then removed and taken to Babylon (2 Kings 25:13–17). Jewish tradition holds that the Temple was destroyed on Tisha B'Av, the 9th day of Av (Hebrew calendar), the same date of the destruction of the Second Temple. Rabbinic sources state that the First Temple stood for 410 years and, based on the 2nd-century work Seder Olam Rabbah, place construction in 832 BCE and destruction in 422 BCE (3338 AM), 165 years later than secular estimates. The Jewish historian Josephus says; "the temple was burnt four hundred and seventy years, six months, and ten days after it was built".[additional citation(s) needed] Solomon's Temple was subsequently replaced with the Second Temple in 515 BCE, following Jewish return from exile. Architecture The description of Solomon's Temple given in I Kings and II Chronicles is remarkably detailed, but attempts to reconstruct it have met many difficulties. The description includes various technical terms that have lost their original meaning to time. Archaeological studies have provided ancient Near Eastern counterparts for architectural features, furnishings and decorative motifs. Contemporary Israeli archaeologist Finkelstein considered Solomon's Temple to be built according to Phoenician design, and its description is in accordance with how Phoenician temples looked; others have described the structure as temple in antis. In 2011, three small portable shrines were discovered in Khirbet Qeiyafa, an archaeological site 30 km (20 mi) from Jerusalem dated to 1025–975 BCE, a range that includes the biblical date for the reigns of David and Solomon. The smaller shrines are boxes shaped with different decorations showing impressive architectonic and decorative styles. One of the excavators, Israeli archaeologist Yosef Garfinkel, suggested that the style and the decoration of these cultic objects are very similar to the biblical description of some features of Solomon's Temple. Archeologists categorize the biblical description of Solomon's Temple as a langbau building. That is, a rectangular building that is longer than it is wide. It is furthermore classified as a tripartite building, consisting of three units; the ulam (porch), the heikal (sanctuary), and the debir (the Holy of Holies). It is also categorized as being a straight-axis temple, meaning that there is a straight line from the entrance to the innermost shrine. The ulam, or porch, featured two bronze pillars, Boaz and Jachin. It is unclear from the biblical descriptions whether the porch was a closed room, a roofed entranceway, or an open courtyard. Thus, it is not known whether the pillars were freestanding or structural elements built into the porch. If they were built into the porch, it could indicate that the design was influenced by similar temples in Syria or even Turkey, home to the ancient Hittite Empire. While most reconstructions of the Temple have the pillars freestanding, Yosef Garfinkel and Madeleine Mumcuoglu finds it likely that the pillars supported a roof over the porch. The porch led to the heikal, main chamber, or sanctuary. It measured 40 cubits in length, 20 cubits in width, and 30 cubits in height and contained a candelabrum, a table and a gold-covered altar used for offerings. In the sanctuary, loaves of Showbread were left as an offering to God. At the far end of the sanctuary there was a wooden door, guarded by two cherubim, leading to the Holy of Holies. The walls of the sanctuary were lined with cedar, on which were carved figures of cherubim, palm trees, and open flowers that were overlaid with gold (1 Kings 6:29–30). Chains of gold further marked it off from the Holy of Holies. The floor of the Temple was of fir overlaid with gold. The doorposts, of olivewood, supported folding doors of fir. The doors of the Holy of Holies were of olivewood. On both sets of doors were carved cherubim, palm trees, and flowers, all being overlaid with gold (1 Kings 6:15 et seq.) This main building was between the outer altar, where most sacrifices were performed, and inside at the far end was the entry to the Holy of Holies, originally containing the Ark of the Covenant. The main hekhal contained a number of sacred ritual objects including the seven-branched candlestick, a golden Altar of Incense, and the table of the showbread. According to 1 Kings 7:48 these tables were of gold, as were also the five candlesticks on each side of the altar. The candle–tongs, basins, snuffers, firepans, and even the hinges of the doors were also gold. The Holy of Holies, also called the "Inner House", was 20 cubits in length, breadth, and height. The usual explanation for the discrepancy between its height and the 30-cubit height of the temple is that its floor was elevated, like the cella of other ancient temples. It was floored and wainscotted with cedar of Lebanon, and its walls and floor were overlaid with gold amounting to 600 talents or roughly 20 metric tons. It contained two cherubim of olivewood, each 10 cubits high and each having outspread wings of 10 cubits span, so that, since they stood side by side, the wings touched the wall on either side and met in the center of the room. There was a two-leaved door between it and the Holy Place overlaid with gold; also, a veil of tekhelet (blue), purple, and crimson and fine linen. It had no windows and was considered the dwelling-place of the "name" of God.[citation needed] The Holy of Holies was prepared to receive and house the Ark; and when the Temple was dedicated, the Ark, containing the original tablets of the Ten Commandments, was placed beneath the cherubim.[citation needed] Chambers were built around the Temple on the southern, western and northern sides (1 Kings 6:5–10). These formed a part of the building and were used for storage. They were probably one story high at first; two more may have been added later. According to the Bible, two courts surrounded the Temple. The Inner Court (1 Kings 6:36), or Court of the Priests (2 Chr. 4:9), was separated from the space beyond by a wall of three courses of hewn stone, surmounted by cedar beams (1 Kings 6:36). It contained the Altar of burnt-offering (2 Chr. 15:8), the Brazen Sea laver (4:2–5, 10) and ten other lavers (1 Kings 7:38, 39). A brazen altar stood before the Temple (2 Kings 16:14), its dimensions 20 cubits square and 10 cubits high (2 Chr. 4:1). The Great Court surrounded the whole Temple (2 Chr. 4:9). It was here that people assembled to worship. (Jeremiah 19:14; 26:2). According to the Hebrew Bible, the "Molten or Brazen Sea" (ים מוצק "cast metal sea") was a large basin in the Temple for ablution of the priests. It is described in 1 Kings 7:23–26 and 2 Chronicles 4:2–5. According to the Bible, it stood in the south-eastern corner of the inner court. It was five cubits high, ten cubits in diameter from brim to brim, and thirty cubits in circumference. The brim was "like the calyx of a lily" and turned outward "about an hand breadth"; or about four inches. It was placed on the backs of twelve oxen, standing with their faces outward. The Book of Kings states that it contains 2000 baths (90 cubic meters), while Chronicles (2 Chr. 4:5–6) states it can hold up to 3000 baths (136 cubic meters) and states that its purpose was to afford opportunity for the purification by immersion of the bodies of the priests. The fact that it was a washbasin that was too large to enter from above lends to the idea that water would likely have flowed from it down into a subcontainer beneath. The water was originally supplied by the Gibeonites but was afterwards brought by a conduit from Solomon's Pools. The molten sea was made of brass or bronze that which Solomon had taken from the captured cities of Hadadezer ben Rehob, king of Zobah (1 Chronicles 18:8). Ahaz later removed this laver from the oxen and placed it on a stone pavement (2 Kings 16:17). It was destroyed by the Neo-Babylonian Empire (2 Kings 25:13). Also outside the temple were 10 lavers, each of which held "forty baths" (1 Kings 7:38), resting on portable holders made of bronze, provided with wheels, and ornamented with figures of lions, cherubim, and palm-trees. The author of the books of the Kings describes their minute details with great interest (1 Kings 7:27–37). Josephus reported that the vessels in the Temple were composed of orichalcum covered in gold in Antiquities of the Jews. Worship During the United Monarchy, the Temple was dedicated to Yahweh, the God of Israel. From the reign of King Manasseh of Judah until King Josiah, Baal and "the host of heaven" were also worshipped there. Until the reforms of Josiah, there was also a statue for the goddess Asherah (2 Kings 23:6) and priestesses wove ritual textiles for her (2 Kings 23:7). Next to the temple was a house for the temple prostitutes (2 Kings 23:7) who performed sacred prostitution at the temple. It is unclear whether the prostitutes included both male and female or just male prostitutes. According to the majority of biblical scholars, Asherah was Yahweh's consort, and she was worshipped alongside Yahweh. This is disputed by a significant minority, who maintain that the asherah in the Temple was a wooden pole, rather than a statue. Although originally a symbol of the goddess, the asherah is argued to have been adopted as a symbol of Yahweh. According to Richard Lowery, Yahweh and Asherah headed a pantheon of other Judean gods that were worshipped at the temple. The temple had chariots of the sun (2 Kings 23:11) and Ezekiel describes a vision of temple worshipers facing east and bowing to the sun (Ezekiel 8:16). Some Bible scholars, such as Margaret Barker, say that these solar elements indicate a solar cult. They may reflect an earlier Jebusite worship of Zedek or possibly a solarized Yahwism.[page needed] According to the Tanakh, the Temple housed the Ark of the Covenant. It says the Ark contained the Ten Commandments and was moved from Kiriath Jearim to Jerusalem by David before being moved into Solomon's temple. A common view among scholars is that the Ark was originally conceived as Yahweh's footstool, above which he was invisibly enthroned. Biblical scholar Francesca Stavrakopoulou states that Yahweh was physically enthroned above the Ark as a cult statue and it was only following the Exile that Yahweh was conceived as unseen and the prohibition on carved images was added to the Ten Commandments. On the other hand, some biblical scholars believe the story of the Ark was written independently and then incorporated into the main biblical narrative just before the exile into Babylon. Biblical scholar Thomas Römer speculates that the Ark may have contained statues of Yahweh and Asherah, and that it could have remained in Kiriath Jearim for much longer, possibly until shortly before the Babylonian conquest. During the Deuteronomic reform of King Josiah, the cult objects of the sun and Asherah were taken out of the temple and the practice of sacred prostitution, and the worship of Baal and the hosts of heaven were stopped. A korban was a kosher animal sacrifice, such as a bull, sheep, goat, or dove that underwent shechita (Jewish ritual slaughter). Sacrifices could also consist of grain, meal, wine, or incense. Offerings were often cooked and most of it eaten by the offeror, with parts given to the Kohen priests and small parts burned on the altar of the Temple in Jerusalem. Only in special cases was all of the offering given only to God, such as in the case of the scapegoat. Under Josiah, sacrifices were centralized at Solomon's temple and other places of sacrifice were abolished. The temple became a major slaughtering center and part of Jerusalem's economy. Archaeological dating Most scholars today agree that a temple had existed on the Temple Mount by the time of the Babylonian siege of Jerusalem (587 BCE), but the identity of its builder and its construction date are strongly debated. Because of the religious and political sensitivities involved, no archaeological excavations and only limited surface surveys of the Temple Mount have been conducted since Charles Warren's expedition of 1867–1870. As of today, there is no solid archaeological evidence for the existence of Solomon's Temple, and the building is not mentioned in surviving extra-biblical accounts, save for perhaps a single fragmented ostracon that mentions a "house of Yahweh" without any further specification. Artifacts previously believed to prove the existence of Solomon's Temple—an ivory pomegranate and a ninth century BCE stone tablet—are now highly contested as to their authenticity. Moreover, starting in the 1980s, biblical minimalists have doubted King Solomon's connection to the temple, sometimes describing him as little more than a hill country chieftain. On the other hand, William G. Dever argues that the biblical description of the Temple itself shows profound similarities with other temples of the time (Phoenician, Assyrian and Philistine), suggesting that this cult structure was actually built by Solomon (whom he sees as an actual king of Israel) in the 10th century BCE, although the biblical description is undoubtedly excessive. These views are shared by the archaeologist Amihai Mazar, who underlines how the description of the Temple in the Bible, albeit exaggerated, is substantially in line with the architectural descriptions already present in the Levant in the second millennium BCE. Yosef Garfinkel and Madeleine Mumcuoglu argue that the discovery of a 9th century BCE temple at Motza, a secondary administrative site in the Kingdom of Judah, implies that there must have been a central temple in the kingdom’s capital. Fabio Porzia and Corinne Bonnet, reflecting on the archaeological parallels between the way Solomon's temple is described and comparable examples of similar temples from around the ancient Near East, demur and conclude that "a gap [...] exists between the biblical accounts which place the temple in the 10th century and the historical considerations which tend towards the 8th and 7th centuries." They suggest that Solomon's temple corresponds more with the 8th-7th century temple architectural models associated with Aram or Assyria than with anything associated with temple architecture from the 10th century. They suggest that the first temple most likely dates to the 8th century and "was retroactively attributed to the great ruler of the 10th century." An ostracon (excavated prior to 1981), sometimes referred to as the House of Yahweh ostracon, was discovered at Tel Arad, dated to the 6th century BCE, which mentions a temple that could be the Temple in Jerusalem. This has been challenged by Fabio Porzia and Corinne Bonnet who wrote that the context and location of the temple mentioned is not known. A thumb-sized ivory pomegranate (which came to light in 1979) measuring 44 millimetres (1.7 in) in height and bearing an ancient Hebrew inscription "Sacred donation for the priests in the House of ---h,]", was believed to have adorned a sceptre used by the high priest in Solomon's Temple. It was considered the most important item of biblical antiquities in the Israel Museum's collection. In 2004, however, experts from the Israel Museum reported the inscription to be a forgery, though the ivory pomegranate itself was dated to the 14th or 13th century BCE. This was based on the report's claim that three incised letters in the inscription stopped short of an ancient break, as they would have if carved after the ancient break was made. Since then, it has been proven that one of the letters was indeed carved prior to the ancient break, and the status of the other two letters are in question. Some paleographers and others have continued to insist that the inscription is ancient, some dispute this, so the authenticity of this writing is still the object of discussion. Another artifact, the Jehoash Inscription, which first came to notice in 2003, contains a 15-line description of King Jehoash's ninth-century BCE restoration of the Temple. Its authenticity was called into question by a report by the Israel Antiquities Authority, which said that the surface patina contained microfossils of foraminifera. As these fossils do not dissolve in water, they cannot occur in a calcium carbonate patina, leading initial investigators to conclude that the patina must be an artificial chemical mix applied to the stone by forgers. As of late 2012, the academic community is split on whether the tablet is authentic or not. Commenting on a 2012 report by geologists arguing for the authenticity of the inscription, in October 2012, Hershel Shanks (who believes the inscription is genuine) wrote the current situation was that most Hebrew language scholars believe that the inscription is a forgery and geologists that it is genuine, and thus "Because we rely on experts, and because there is an apparently irresolvable conflict of experts in this case, BAR has taken no position with respect to the authenticity of the Jehoash Inscription." The historian Flavius Josephus, writing centuries later in 1st century CE, says that "Solomon began to build the temple in the fourth year of his reign, on the second month, which the Macedonians call Artemisius, and the Hebrews Jar, five hundred and ninety two years after the exodus out of Egypt, but after one thousand and twenty years from Abraham's coming out of Mesopotamia into Canaan and after the deluge one thousand four hundred and forty years; and from Adam, the first man who was created, until Solomon built the temple, there had past in all three thousand one hundred and two years."[non-primary source needed] In Against Apion, Josephus mentions that according to the annals of the Phoenician city-state of Tyre, Solomon's Temple was built on the 12th year of Hiram I of Tyre and 143 years and 8 months before the Tyrians founded Carthage. The foundation date of Carthage is usually dated to 814 BCE, thus, according to Josephus, the construction of the Temple should be dated to circa 958/9 BCE, a date that lies within the conventional dates of Solomon's reign between 970 and 931 BCE. In Islam The Quran refers to Solomon's Temple in the seventh verse of Surah Al-Isrāʾ (The Night Journey, aka Bani Israil): If you [the Children of Israel] act rightly, it is for your own good, but if you do wrong, it is to your own loss. And when the second warning would come to pass, your enemies would ˹be left to˺ totally disgrace you and enter the Temple ˹of Jerusalem˺ as they entered it the first time, and utterly destroy whatever would fall into their hands. Quranic commentators such as Muhammad al-Tahir ibn Ashur have postulated that this verse refers specifically to the Temple of Solomon. According to the narrative in Islam, the Temple in Jerusalem was originally a mosque commissioned by Solomon and built by jinn on the commandment of Allah, with the purpose of serving as the qibla of the Israelites. In the early years of Islam, Prophet Muhammad and his followers faced Jerusalem for prayers until the city of Mecca (specifically its Kaaba) superseded the former as the new qibla. Legacy Rituals in Freemasonry refer to King Solomon and the building of his Temple. Masonic buildings, where lodges and their members meet, are sometimes called "temples"; an allegoric reference to King Solomon's Temple. Kabbalah views the design of the Temple of Solomon as representative of the metaphysical world and the descending light of the creator through Sefirot of the Tree of Life. The levels of the outer, inner and priest's courts represent three lower worlds of Kabbalah. The Boaz and Jachin pillars at the entrance of the temple represent the active and passive elements of the world of Atziluth. The original menorah and its seven branches represent the seven lower Sephirot of the Tree of Life. The veil of the Holy of Holies and the inner part of the temple represent the Veil of the Abyss on the Tree of Life, behind which the Shekhinah or Divine Presence hovers. Biblical descriptions of the temple have inspired modern replicas and influenced later structures around the world. El Escorial, a historical residence of the King of Spain built in the 16th century was constructed from a plan based on the descriptions of Solomon's temple. The same architectural layout of the temple was adopted in synagogues leading to the hekhal being applied in Sephardi usage to the Ashkenazi Torah ark, the equivalent of the nave. Solomon's Temple appears in the film Solomon and Sheba (1959). It also appears in the Assassin's Creed video game series. Other contemporary temples There is archaeological and written evidence of three Israelite temples, either contemporary or of very close date, dedicated to Yahweh (Elephantine temple, probably Arad too), either in the Land of Israel or in Egypt. Two of them have the same general outline as given by the Bible for the Jerusalem Temple. See also Notes and references Further reading External links |

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 Twitter X, formerly known as Twitter,[b] is an American microblogging and social networking service. It is one of the world's largest social media platforms and one of the most-visited websites. Users can share short text messages, images, and videos in short posts (commonly and unofficially known as "tweets") and like other users' content. The platform also includes direct messaging, video and audio calling, bookmarks, lists, communities, Grok chatbot integration, job search, and a social audio feature (X Spaces). Users can vote on context added by approved users using the Community Notes feature. The platform, initially called twttr, was created in March 2006 by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams, and was launched in July of that year; it was renamed Twitter some months later. The platform grew quickly; by 2012 more than 100 million users produced 340 million daily tweets. Twitter, Inc., was based in San Francisco, California, and had more than 25 offices around the world. A signature characteristic of the service initially was that posts were required to be brief. Posts were initially limited to 140 characters, which was changed to 280 characters in 2017. The limitation was removed for subscribed accounts in 2023. 10% of users produce over 80% of tweets. In 2020, it was estimated that approximately 48 million accounts (15% of all accounts) were run by Internet bots rather than humans. The service is owned by the American company X Corp., which was established to succeed the prior owner Twitter, Inc. in March 2023 following the October 2022 acquisition of Twitter by Elon Musk for US$44 billion. Musk stated that his goal with the acquisition was to promote free speech on the platform. Since his acquisition, the platform has been criticized for enabling the increased spread of disinformation and hate speech. Linda Yaccarino succeeded Musk as CEO on June 5, 2023, with Musk remaining as the chairman and the chief technology officer. In July 2023, Musk announced that Twitter would be rebranded to "X" and the bird logo would be retired, a process which was completed by May 2024. In March 2025, X Corp. was acquired by xAI, Musk's artificial intelligence company. The deal, an all-stock transaction, valued X at $33 billion, with a full valuation of $45 billion when factoring in $12 billion in debt. Meanwhile, xAI itself was valued at $80 billion. In July 2025, Linda Yaccarino stepped down from her role as CEO. The X site has been accused of becoming increasingly right-wing and catering to hate groups. In February 2026, the platform's owner, xAI, was acquired by SpaceX; this marked the sixth time where the social media platform has changed hands and the third time under Musk's ownership. History Jack Dorsey claims to have introduced the idea of an individual using an SMS service to communicate to a small group in 2006. The original project code name for the service was twttr, an idea that Williams later ascribed to Noah Glass, inspired by Flickr and the five-character length of American SMS short codes. The decision was also partly due to the fact that the domain twitter.com was already in use, and it was six months after the launch of twttr that the crew purchased the domain and changed the name of the service to Twitter. Work on the project started in February 2006. The first Twitter prototype, developed by Dorsey and contractor Florian Weber, was used as an internal service for Odeo employees. The full version was introduced publicly on July 15, 2006. In October 2006, Biz Stone, Evan Williams, Dorsey, and other members of Odeo formed Obvious Corporation and acquired Odeo from the investors and shareholders. Williams fired Glass, who was silent about his part in Twitter's startup until 2011. Twitter spun off into its own company in April 2007. The tipping point for Twitter's popularity was the 2007 South by Southwest Interactive (SXSWi) conference. During the event, Twitter usage increased from 20,000 tweets per day to 60,000. The company experienced rapid initial growth thereafter. In 2009, Twitter won the "Breakout of the Year" Webby Award. In February 2010, Twitter users were sending 50 million tweets per day. By March 2010, the company recorded over 70,000 registered applications. In June 2010, about 65 million tweets were posted each day, equaling about 750 tweets sent each second, according to Twitter. As noted on Compete.com, Twitter moved up to the third-highest-ranking social networking site in January 2009 from its previous rank of twenty-second. From September through October 2010, the company began rolling out "New Twitter", an entirely revamped edition of twitter.com. Changes included the ability to see pictures and videos without leaving Twitter itself by clicking on individual tweets which contain links to images and clips from a variety of supported websites, including YouTube and Flickr, and a complete overhaul of the interface. In 2019, Twitter was announced to be the 10th most downloaded mobile app of the decade, from 2010 to 2019. On March 21, 2012, Twitter celebrated its sixth birthday by announcing that it had 140 million users, a 40% rise from September 2011, who were sending 340 million tweets per day. On June 5, 2012, a modified logo was unveiled through the company blog, removing the text to showcase the slightly redesigned bird as the sole symbol of Twitter. On December 18, 2012, Twitter announced it had surpassed 200 million monthly active users.[citation needed] In September 2013, the company's data showed that 200 million users sent over 400 million tweets daily, with nearly 60% of tweets sent from mobile devices. In April 2014, Twitter underwent a redesign that made the site resemble Facebook somewhat, with a profile picture and biography in a column left to the timeline, and a full-width header image with parallax scrolling effect.[c] Late in 2015, it became apparent that growth had slowed, according to Fortune, Business Insider, Marketing Land and other news websites including Quartz (in 2016). In 2019, Twitter released another redesign of its user interface. By the start of 2019[update], Twitter had more than 330 million monthly active users. Twitter then experienced considerable growth during the COVID-19 pandemic in 2020. The platform also was increasingly used for misinformation related to the pandemic. Twitter started marking tweets which contained misleading information, and adding links to fact-checks. In 2021, Twitter began the research phase of Bluesky, an open source decentralized social media protocol where users can choose which algorithmic curation they want. The same year, Twitter also released Twitter Spaces, a social audio feature; "super follows", a way to subscribe to creators for exclusive content; and a beta of "ticketed Spaces", which makes access to certain audio rooms paid. Twitter unveiled a redesign in August 2021, with adjusted colors and a new Chirp font, which improves the left-alignment of most Western languages. Elon Musk completed his acquisition of Twitter in October 2022; Musk acted as CEO of Twitter until June 2023 when he was succeeded by Linda Yaccarino. Twitter was rebranded to X on July 23, 2023, and its domain name changed from twitter.com to x.com on May 17, 2024. Yaccarino resigned on July 9, 2025. Now operating as X, the platform closely resembles its predecessor but includes additional features such as long-form texts, account monetization options, audio-video calls, integration with xAI's Grok chatbot, job search, and a repurposing of the platform's verification system as a subscription premium. Several legacy Twitter features were removed from the site after Musk acquired Twitter, including Circles, NFT profile pictures, and the experimental pronouns in profiles feature. Musk's aims included transforming X into a "digital town square" and an "everything app" akin to WeChat. X has faced significant controversy post-rebranding. Issues such as the release of the Twitter Files, suspension of ten journalists' accounts, and labeling media outlets as "state-affiliated" and restricting their visibility have sparked criticism. Despite Musk stepping down as CEO, X continues to struggle with challenges such as viral misinformation, hate speech (especially antisemitism), and child pornography. In response to allegations it deemed unfair, X Corp. has pursued legal action against nonprofit organizations Media Matters and the Center for Countering Digital Hate. Appearance and features Posts (commonly and unofficially called "tweets") are publicly visible by default, but senders can restrict message delivery to their followers. Users can mute users they do not wish to interact with, block accounts from viewing their posts, and remove accounts from their followers list. Users can post via the website, compatible external applications, or by Short Message Service (SMS). Users may subscribe to other users' posts—this is known as "following" and subscribers are known as "followers" or "tweeps", a portmanteau of Twitter and peeps. Posts can be forwarded by other users to their own feed, a process commonly called a "retweet" (officially "repost"). In 2015, Twitter launched "quote tweet", a feature (now named "quote repost") which allows users to add a comment to their post, embedding one post in the other. Users can also "like" individual tweets. The counters for likes, retweets, and replies appear next to the respective buttons in timelines such as on profile pages and search results. Counters for likes and reposts exist on a post's standalone page too. Since 2020, quote tweets have their own counter. Until the legacy desktop front end that was discontinued in 2020, a row with miniature profile pictures of up to ten liking or retweeting users was displayed, as well as a tweet reply counter next to the according button on a tweet's page. Twitter allows users to update their profile via their phones either by text messaging or by apps. Twitter announced in a tweet in 2022, that the ability to edit a tweet was being tested for select users. Eventually, all Twitter Blue subscribers would be able to use the feature. Users can group posts together by topic or type by use of hashtags – words or phrases prefixed with a "#" sign. Similarly, the "@" sign followed by a username is used for mentioning or replying to other users. In 2014, Twitter introduced hashflags, special hashtags that automatically generate a custom emoji next to them for a period of time. Hashflags may be generated by Twitter themselves or purchased by corporations. To repost a message from another user and share it with one's own followers, a user can click the repost button within the post. Users can reply to other accounts' replies. Users can hide replies to their messages and select who can reply to each of their tweets before sending them: anyone, accounts who follow the post's author, specific accounts, or none. The original, strict 140 character limit was gradually relaxed. In 2016, Twitter announced that attachments, links, and media such as photos, videos, and the person's handle, would no longer count. In 2017, Twitter handles were similarly excluded and Twitter doubled its character limitation to 280. Under the new limit, glyphs are counted as a variable number of characters, depending upon the script they are from. From 2023 Twitter Blue users could create posts with up to 4,000 characters in length. t.co is a URL shortening service created by Twitter. It is only available for links posted to Twitter and not general use. All links posted to Twitter use a t.co wrapper. Twitter intended the service to protect users from malicious sites, and to use it to track clicks on links within tweets. In June 2011, Twitter announced its own integrated photo-sharing service that enables users to upload a photo and attach it to a Tweet right from Twitter.com. Users now have the ability to add pictures to Twitter's search by adding hashtags to the tweet. Twitter plans to provide photo galleries designed to gather and syndicate all photos that a user has uploaded on Twitter and third-party services such as TwitPic. In 2016 Twitter introduced the ability to add a caption of up to 480 characters to each image attached to a tweet, accessible via screen reading software or by hovering the mouse above a picture inside TweetDeck. In 2022, Twitter made the ability to add and view captions globally available. Descriptions can be added to any uploaded image with a limit of 1000 characters. Images that have a description will feature a badge that says ALT in the bottom left corner, which will bring up the description when clicked. In 2015, Twitter began to roll out the ability to attach poll questions to tweets. Polls are open for up to 7 days, and voters are not identified. In Twitter's early years, users could communicate with Twitter using SMS. This was discontinued in most countries in April 2020 after hackers exposed vulnerabilities. In 2016, Twitter began to place a larger focus on live streaming video programming, hosting events including streams of the Republican and Democratic conventions, and winning a bid for non-exclusive streaming rights to ten NFL games in 2016. In 2017, Twitter announced that it planned to construct a 24-hour streaming video channel hosted within the service, featuring content from various partners. Twitter announced a number of new and expanded partnerships for its streaming video services at the event, including Bloomberg, BuzzFeed, Cheddar, IMG Fashion, Live Nation Entertainment, Major League Baseball, MTV and BET, NFL Network, the PGA Tour, The Players' Tribune, Ben Silverman and Howard T. Owens' Propagate, The Verge, Stadium and the WNBA. as of the first quarter of 2017[update], Twitter had over 200 content partners, who streamed over 800 hours of video over 450 events. Twitter Spaces is a social audio feature that enables users to host or participate in a live-audio virtual environment called space for conversation. A maximum of 13 people are allowed onstage. The feature was initially limited to users with at least 600 followers, but since October 2021, any Twitter user can create a Space. In March 2020, Twitter began to test a stories feature known as "fleets" in some markets, which officially launched on November 17, 2020. Fleets could contain text and media, are only accessible for 24 hours after they are posted, and are accessed within the Twitter app; Twitter announced it would start implementing advertising into fleets in June 2021. Fleets were removed in August 2021; Twitter had intended for fleets to encourage more users to tweet regularly, but instead they were generally used by already-active users. Twitter introduced its "trends" feature in mid-2008, an algorithmic lists of trending topics among users. A word or phrase mentioned can become "trending topic" based on an algorithm. Because a relatively small number of users can affect trending topics through a concerted campaign, the feature has been the targeted of concerted manipulation campaigns. While some campaigns are innocuous, others have promoted conspiracy theories or hoaxes, or sought to amplify extremist messages. Some featured trends are globally displayed, while others are limited to a specific country. A 2021 study by EPFL researchers found that frequent "ephemeral astroturfing" efforts targeted at Trends; from 2015 to 2019, "47% of local trends in Turkey and 20% of global trends are fake, created from scratch by bots...The fake trends discovered include phishing apps, gambling promotions, disinformation campaigns, political slogans, hate speech against vulnerable populations and even marriage proposals." The MIT Technology Review reported that, as of 2022, Twitter "sometimes manually overrides particularly objectionable trends" and, for some trends, used both algorithmic and human input to select representative tweets with context. In late 2009, the "Twitter Lists" feature was added, making it possible for users to follow a curated list of accounts all at once, rather than following individual users. Currently,[when?] lists can be set to either public or private. Public lists may be recommended to users via the general Lists interface and appear in search results. If a user follows a public list, it will appear in the "View Lists" section of their profile, so that other users may quickly find it and follow it as well. Private lists can only be followed if the creator shares a specific link to their list. Lists add a separate tab to the Twitter interface with the title of the list, such as "News" or "Economics". In October 2015, Twitter introduced "Moments"—a feature that allows users to curate tweets from other users into a larger collection. Twitter initially intended the feature to be used by its in-house editorial team and other partners; they populated a dedicated tab in Twitter's apps, chronicling news headlines, sporting events, and other content. In September 2016, creation of moments became available to all Twitter users. On October 21, 2021, a report based on a "long-running, massive-scale randomized experiment" that analyzed "millions of tweets sent between 1 April and 15 August 2020", found that Twitter's machine learning recommendation algorithm amplified right-leaning politics on personalized user Home timelines.: 1 The report compared seven countries with active Twitter users where data was available (Germany, Canada, the United Kingdom, Japan, France, and Spain) and examined tweets "from major political groups and politicians".: 4 Researchers used the 2019 Chapel Hill Expert Survey (CHESDATA) to position parties on political ideology within each country.: 4 The "machine learning algorithms", introduced by Twitter in 2016, personalized 99% of users' feeds by displaying tweets (even older tweets and retweets from accounts the user had not directly followed) that the algorithm had "deemed relevant" to the users' past preferences.: 4 Twitter randomly chose 1% of users whose Home timelines displayed content in reverse-chronological order from users they directly followed.: 2 In 2026, a report released in Nature found X's feed algorithm promotes conservative content and deprioritizes traditional media in favor of conservative activists. Based on an analysis of 4,965 participants in 2023 over 7 weeks, it found switching from a chronological feed to an algorithmic feed increased engagement and shifted users to adopt conservative political positions, particularly around "policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine". It also found that exposure to algorithmic content led users to follow conservative political accounts and that users kept following them even after the algorithm was switched off.: 1 Twitter had mobile apps for iPhone, iPad, and Android. In April 2017, Twitter introduced Twitter Lite, a progressive web app designed for regions with unreliable and slow Internet connections, with a size of less than one megabyte, designed for devices with limited storage capacity. On June 3, 2021, Twitter announced a paid subscription service called Twitter Blue. Following Twitter's rebranding to "X", the subscription service was initially renamed to X Blue (or simply Blue), and, on August 5, 2023, was rebranded as X Premium (or simply Premium). The subscription provides additional premium features to the service. In November 2023 a "Premium+" subscription was launched, with a higher monthly fee giving benefits such as the omission of adverts on For You and Following feeds. In November 2022, Musk announced plans to add account verification and the ability to upload longer audio and video to Twitter Blue. A previous perk offering advertising-free news articles from participating publishers was dropped, but Musk stated that Twitter did want to work with publishers on a similar "paywall bypass" perk. Musk had pushed for a more expensive version of Twitter Blue following his takeover, arguing that it would be needed to offset a decline in advertising revenue. Twitter states that paid verification is required to help reduce fraudulent accounts. The verification marker was included in a premium tier of Twitter Blue introduced on November 9, 2022, priced at US$7.99 per month. On November 11, 2022, after the introduction of this feature led to prominent issues involving accounts using the feature to impersonate public figures and companies, Twitter Blue with verification was temporarily suspended. After about a month, Twitter Blue was relaunched on December 12, 2022, though for those purchasing the service through the iOS app store, the cost will be $10.99 a month as to offset the 30% revenue split that Apple takes. Twitter initially grandfathered users and entities that had gained verification due to their status as public figures, referring to them as "legacy verified accounts" that "may or may not be notable". On March 25, 2023, it was announced that "legacy" verification status would be removed; a subscription will be required to retain verified status, costing $1,000 per-month for organizations (which are designated with a gold verified symbol), plus an additional $50 for each "affiliate". The change was originally scheduled for April 1, 2023, but was delayed to April 20, 2023, following criticism of the changes. Musk also announced plans for the "For You" timeline to prioritize verified accounts and user followers only beginning April 15, 2023, and threatened to only allow verified users to participate in polls (although the latter change has yet to occur). Effective April 21, 2023, X requires companies to participate in the verified organizations program to purchase advertising on the platform, although companies that spend at least $1,000 on advertising per-month automatically receive membership in the program at no additional cost. From April 25, 2023, verified users are now prioritized in replies to tweets. In 2021, the company opened applications for its premium subscription options called Super Follows. This lets eligible accounts charge $2.99, $4.99 or $9.99 per month to subscribe to the account. The launch only generated about $6,000 in its first two weeks. In 2023, the Super Follows feature was rebranded as simply "subscriptions", allowing users to publish exclusive long-form posts and videos for their subscribers; the pivot in marketing was reportedly intended to help compete with Substack. In May 2021, Twitter began testing a Tip Jar feature on its iOS and Android clients. The feature allows users to send monetary tips to certain accounts, providing a financial incentive for content creators on the platform. The Tip Jar is optional and users can choose whether or not to enable tips for their account. On September 23, 2021, Twitter announced that it will allow users to tip users on the social network with bitcoin. The feature will be available for iOS users. Previously, users could tip with fiat currency using services such as Square's Cash App and PayPal's Venmo. Twitter will integrate the Strike bitcoin lightning wallet service. It was noted that at this current time, Twitter will not take a cut of any money sent through the tips feature. On August 27, 2021, Twitter rolled out Ticketed Spaces, which let Twitter Spaces hosts charge between $1 and $999 for access to their rooms. In April 2022, Twitter announced that it will partner with Stripe, Inc. for piloting cryptocurrency payouts for limited users in the platform. Eligible users of Ticketed Spaces and Super Follows will be able to receive their earnings in the form of USD coin, a stablecoin whose value is that of the U.S. dollar. Users can also hold their earnings in crypto wallets, and then exchange them into other cryptocurrencies. In July 2021, Twitter began testing a "Shop module" for iOS users in the US, allowing accounts associated with brands to display a carousel of cards on their profiles showcasing products. Unlike the Buy button, where order fulfillment was handed from within Twitter, these cards are external links to online storefronts from which the products may be purchased. In March 2022, Twitter expanded the test to allow companies to showcase up to 50 products on their profiles. In November 2021, Twitter introduced support for "shoppable" live streams, in which brands can hold streaming events that similarly display banners and pages highlighting products that are featured in the presentation. In January 2025, X announced plans to introduce an "X Money Account" feature in 2025. The product would be a digital wallet and enable X users to move funds between traditional bank accounts and their digital wallet and make instant peer-to-peer payments. Visa was announced as partnering with X on the project and, at least initially, cryptocurrencies would not be supported. Usage Daily user estimates vary as the company does not publish statistics on active accounts. A February 2009 Compete.com blog entry ranked Twitter as the third most used social network based on their count of 6 million unique monthly visitors and 55 million monthly visits. An April 2017 a statista.com blog entry ranked Twitter as the tenth most used social network based on their count of 319 million monthly visitors. Its global user base in 2017 was 328 million. According to Musk, the platform had 500 million monthly active users in March 2023, 550 million in March 2024, and 600 million in May 2024. In 2009, Twitter was mainly used by older adults who might not have used other social sites before Twitter. According to comScore only 11% of Twitter's users were aged 12 to 17. According to a study by Sysomos in June 2009, women made up a slightly larger Twitter demographic than men—53% over 47%. It also stated that 5% of users accounted for 75% of all activity. According to Quantcast, 27 million people in the US used Twitter in September 2009; 63% of Twitter users were under 35 years old; 60% of Twitter users were Caucasian, but a higher than average (compared to other Internet properties) were African American/black (16%) and Hispanic (11%); 58% of Twitter users have a total household income of at least US$60,000. The prevalence of African American Twitter usage and in many popular hashtags has been the subject of research studies. Twitter grew from 100 million monthly active users (MAUs) in September 2011, to 255 million in March 2014, and more than 330 million in early 2019. In 2013, there were over 100 million users actively using Twitter daily and about 500 million tweets every day. A 2016 Pew research poll found that Twitter is used by 24% of all online US adults. It was equally popular with men and women (24% and 25% of online Americans respectively), but more popular with younger generations (36% of 18–29-year olds). A 2019 survey conducted by the Pew Foundation found that Twitter users are three times as likely to be younger than 50 years old, with the median age of adult U.S. users being 40. The survey found that 10% of users who are most active on Twitter are responsible for 80% of all tweets. San Antonio-based market-research firm Pear Analytics analyzed 2,000 tweets (originating from the United States and in English) over a two-week period in August 2009 from 11:00 am to 5:00 pm (CST) and separated them into six categories. Pointless babble made up 40%, with 38% being conversational. Pass-along value had 9%, self-promotion 6% with spam and news each making 4%. Despite Jack Dorsey's own open contention that a message on Twitter is "a short burst of inconsequential information", social networking researcher danah boyd responded to the Pear Analytics survey by arguing that what the Pear researchers labeled "pointless babble" is better characterized as "social grooming" or "peripheral awareness" (which she justifies as persons "want[ing] to know what the people around them are thinking and doing and feeling, even when co-presence isn't viable"). Similarly, a survey of Twitter users found that a more specific social role of passing along messages that include a hyperlink is an expectation of reciprocal linking by followers. According to research published in April 2014, around 44% of user accounts have never tweeted. About 22% of Americans say they have used Twitter, according to a 2019 Pew Research Center survey. In 2009, Nielsen Online reported that Twitter had a user-retention rate of 40%. Many people stop using the service after a month; therefore the site may potentially reach only about 10% of all Internet users. Noting how demographics of Twitter users differ from the average Americans, commentators have cautioned against media narratives that treat Twitter as representative of the population, adding that only 10% of users Tweet actively, and that 90% of Twitter users have Tweeted no more than twice. In 2016, shareholders sued Twitter, alleging it "artificially inflated its stock price by misleading them about user engagement". The company announced on September 20, 2021, that it would pay $809.5 million to settle this class-action lawsuit. As of 2026[update], usage of X on mobile devices has been in a progressive decline. At the same time, mobile usage of the rival social network Threads has been increasing. In January 2026, Threads usage finally rose to match that of X. X still remains the dominant network on non-mobile traffic. Branding Before its rebranding to X, Twitter was internationally identifiable by its signature bird logo, or the Twitter Bird. The original logo, which was simply the word Twitter, was in use from its launch in March 2006. It was accompanied by an image of a bird which was later discovered to be a piece of clip art created by the British graphic designer Simon Oxley. A new logo had to be redesigned by founder Biz Stone with help from designer Philip Pascuzzo, which resulted in a more cartoon-like bird in 2009. This version had been named "Larry the Bird" after Larry Bird of the NBA's Boston Celtics fame. Within a year, the Larry the Bird logo underwent a redesign by Stone and Pascuzzo to eliminate the cartoon features, leaving a solid silhouette of Larry the Bird that was used from 2010 through 2012. In 2012, Douglas Bowman created a further simplified version of Larry the Bird, keeping the solid silhouette but making it more similar to a mountain bluebird. This logo was simply called the "Twitter Bird" and was used until July 2023. On July 22, 2023, Elon Musk announced that the service would be rebranded to "X", in his pursuit of creating an "everything app". Musk's profile picture, along with the platform's official accounts, and the icons when browsing/signing up for the platform, were updated to reflect the new logo. The logo resembles the Unicode mathematical alphanumeric symbol U+1D54F 𝕏 MATHEMATICAL DOUBLE-STRUCK CAPITAL X for the letter "X" styled in double-strike bold. Mike Proulx of The New York Times was critical of this change, saying the brand value has been "wiped out". Mike Carr says the new logo gives a "'Big Brother' tech overlord vibe" in contrast to the "cuddly" nature of the previous bird logo. Users review bombed the newly rebranded "X" app on the iOS App Store on the day it was revealed, and Rolling Stone's Miles Klee said that the rebrand "reeks of desperation". Finances On April 13, 2010, Twitter announced plans to offer paid advertising for companies that would be able to purchase "promoted tweets" to appear in selective search results on the Twitter website, similar to Google Adwords' advertising model. Users' photos can generate royalty-free revenue for Twitter, and an agreement with World Entertainment News Network (WENN) was announced in May 2011. Twitter generated an estimated US$139.5 million in advertising sales during 2011. In June 2011, Twitter announced that it would offer small businesses a self-service advertising system. The self-service advertising platform was launched in March 2012 to American Express card members and merchants in the U.S. on an invite-only basis. To continue their advertising campaign, Twitter announced on March 20, 2012, that promoted tweets would be introduced to mobile devices. In April 2013, Twitter announced that its Twitter Ads self-service platform, consisting of promoted tweets and promoted accounts, was available to all U.S. users without an invite. On August 3, 2016, Twitter launched Instant Unlock Card, a new feature that encourages people to tweet about a brand to earn rewards and use the social media network's conversational ads. The format itself consists of images or videos with call-to-action buttons and a customizable hashtag. In October 2017, Twitter banned the Russian media outlets RT and Sputnik from advertising on their website following the conclusions of the U.S. national intelligence report the previous January that both Sputnik and RT had been used as vehicles for Russia's interference in the 2016 US presidential election. Maria Zakharova for the Russian foreign ministry said the ban was a "gross violation" by the US of free speech. In October 2019, Twitter announced it would stop running political ads on its ad platform effective November 22. This resulted from several spurious claims made by political ads. Company CEO Dorsey clarified that Internet advertising had great power and was extremely effective for commercial advertisers, the power brings significant risks to politics where crucial decisions impact millions of lives. The company reversed the ban in August 2023, publishing criteria governing political advertising which do not allow the promotion of false or misleading content, and requiring advertisers to comply with laws, with compliance being the sole responsibility of the advertiser. In April 2022, Twitter announced a ban on "misleading" advertisements that go against "the scientific consensus on climate change". While the company did not give full guidelines, it stated that the decisions would be made with the help of "authoritative sources", including the Intergovernmental Panel on Climate Change. A 2025 article in The Wall Street Journal reported that Verizon, Ralph Lauren Corporation, and at least four other companies signed advertising contracts with X following legal threats from Musk and CEO Linda Yaccarino. X has been fined several times for non-compliance with laws and regulations. On May 25, 2022, Twitter was fined $150 million by the Federal Trade Commission and the United States Department of Justice for collecting users' contact details and using them for targeted advertising. In December 2025, the European Commission fined X €120 million for alleged non-compliance with requirements of the Digital Services Act. Days later, X banned the European Commission from advertising on the platform. Technology X relies on open-source software. The X web interface uses the Ruby on Rails framework, deployed on a performance enhanced Ruby Enterprise Edition implementation of Ruby.[needs update] In the early days of Twitter, tweets were stored in MySQL databases that were temporally sharded (large databases were split based on time of posting). After the huge volume of tweets coming in caused problems reading from and writing to these databases, the company decided that the system needed re-engineering. From Spring 2007 to 2008, the messages were handled by a Ruby persistent queue server called Starling. Since 2009, implementation has been gradually replaced with software written in Scala. The switch from Ruby to Scala and the JVM has given Twitter a performance boost from 200 to 300 requests per second per host to around 10,000–20,000 requests per second per host. This boost was greater than the 10x improvement that Twitter's engineers envisioned when starting the switch. The continued development of Twitter has also involved a switch from monolithic development of a single app to an architecture where different services are built independently and joined through remote procedure calls. As of April 6, 2011, Twitter engineers confirmed that they had switched away from their Ruby on Rails search stack to a Java server they call Blender. Individual tweets are registered under unique IDs called snowflakes, and geolocation data is added using 'Rockdove'. The URL shortener t.co then checks for a spam link and shortens the URL. Next, the tweets are stored in a MySQL database using Gizzard, and the user receives an acknowledgement that the tweets were sent. Tweets are then sent to search engines via the Firehose API. The process is managed by FlockDB and takes an average of 350 ms. On August 16, 2013, Raffi Krikorian, Twitter's vice president of platform engineering, shared in a blog post that the company's infrastructure handled almost 143,000 tweets per second during that week, setting a new record. Krikorian explained that Twitter achieved this record by blending its homegrown and open source technologies. The service's API allows other web services and applications to integrate with Twitter. Developer interest in Twitter began immediately following its launch, prompting the company to release the first version of its public API in September 2006. The API quickly became iconic as a reference implementation for public REST APIs and is widely cited in programming tutorials. From 2006 until 2010, Twitter's developer platform experienced strong growth and a highly favorable reputation. Developers built upon the public API to create the first Twitter mobile phone clients as well as the first URL shortener. Between 2010 and 2012, however, Twitter made a number of decisions that were received unfavorably by the developer community. In 2010, Twitter mandated that all developers adopt OAuth authentication with just 9 weeks of notice. Later that year, Twitter launched its own URL shortener, in direct competition with some of its most well-known third-party developers. And in 2012, Twitter introduced stricter usage limits for its API, "completely crippling" some developers. While these moves successfully increased the stability and security of the service, they were broadly perceived as hostile to developers, causing them to lose trust in the platform. In July 2020, Twitter released version 2.0 of the public API and began showcasing Twitter apps made by third-party developers on its Twitter Toolbox section in April 2022. In January 2023, Twitter ended third-party access to its APIs, forcing all third-party Twitter clients to shut down. This was controversial among the developer community, as many third-party apps predated the company's official apps, and the change was not announced beforehand. Twitterrific's Sean Heber confirmed in a blog post that the 16-year-old app has been discontinued. "We are sorry to say that the app's sudden and undignified demise is due to an unannounced and undocumented policy change by an increasingly capricious Twitter – a Twitter that we no longer recognize as trustworthy nor want to work with any longer." In February 2023, Twitter announced it would be ending free access to Twitter API, and began offering paid tier plans with a more limited access. On April 17, 2012, Twitter announced it would implement an "Innovators Patent Agreement" which would obligate Twitter to only use its patents for defensive purposes.[clarify] Twitter has a history of both using and releasing open-source software while overcoming technical challenges of their service. A page in their developer documentation thanks dozens of open-source projects which they have used, from revision control software like Git to programming languages such as Ruby and Scala. Software released as open source by the company includes the Gizzard Scala framework for creating distributed datastores, the distributed graph database FlockDB, the Finagle library for building asynchronous RPC servers and clients, the TwUI user interface framework for iOS, and the Bower client-side package manager. The popular Bootstrap frontend framework was also started at Twitter and is 10th most popular repository on GitHub. On March 31, 2023, Twitter released the source code for Twitter's recommendation algorithm, which determines what tweets show up on the user's personal timeline, to GitHub. According to Twitter's blog post: "We believe that we have a responsibility, as the town square of the internet, to make our platform transparent. So today we are taking the first step in a new era of transparency and opening much of our source code to the global community." Elon Musk, the CEO at the time, had been promising the move for a while – on March 24, 2022, before he owned the site, he polled his followers about whether Twitter's algorithm should be open source, and around 83% of the responses said "yes". In February, he promised it would happen within a week before pushing back the deadline to March 31. Twitter updated its source code repository in January 2026 with a new algorithm that depends on an external large language model (such as Grok) to evaluate posts, leading researchers to describe the disclosed source code as lacking in transparency. Also in March 2023, Twitter suffered a security attack which resulted in proprietary code being released. Twitter then had the leaked source code removed. Twitter introduced the first major redesign of its user interface in September 2010, adopting a dual-pane layout with a navigation bar along the top of the screen, and an increased focus on the inline embedding of multimedia content. Critics considered the redesign an attempt to emulate features and experiences found in mobile apps and third-party Twitter clients. The new layout was revised in 2011 with a focus on continuity with the web and mobile versions, introducing "Connect" (interactions with other users such as replies) and "Discover" (further information regarding trending topics and news headlines) tabs, an updated profile design, and moving all content to the right pane (leaving the left pane dedicated to functions and the trending topics list). In March 2012, Twitter became available in Arabic, Farsi, Hebrew and Urdu, the first right-to-left language versions of the site. In 2023 the Twitter Web site listed 34 languages supported by Twitter.com. In September 2012, a new layout for profiles was introduced, with larger "covers" that could be customized with a custom header image, and a display of the user's recent photos posted. The "Discover" tab was discontinued in April 2015, and was succeeded on the mobile app by an "Explore" tab—which features trending topics and moments. In September 2018, Twitter began to migrate selected web users to its progressive web app (based on its Twitter Lite experience for mobile web), reducing the interface to two columns. Migrations to this iteration of Twitter increased in April 2019, with some users receiving it with a modified layout. In July 2019, Twitter officially released this redesign, with no further option to opt-out while logged in. It is designed to further-unify Twitter's user experience between the web and mobile application versions, adopting a three-column layout with a sidebar containing links to common areas (including "Explore" that has been merged with the search page) which previously appeared in a horizontal top bar, profile elements such as picture and header images and biography texts merged into the same column as the timeline, and features from the mobile version (such as multi-account support, and an opt-out for the "top tweets" mode on the timeline). In response to early Twitter security breaches, the United States Federal Trade Commission (FTC) brought charges against the service; the charges were settled on June 24, 2010. This was the first time the FTC had taken action against a social network for security lapses. The settlement requires Twitter to take a number of steps to secure users' private information, including maintenance of a "comprehensive information security program" to be independently audited biannually. After a number of high-profile hacks of official accounts, including those of the Associated Press and The Guardian, in April 2013, Twitter announced a two-factor login verification as an added measure against hacking. On July 15, 2020, a major hack of Twitter affected 130 high-profile accounts, both verified and unverified ones such as Barack Obama, Bill Gates, and Elon Musk; the hack allowed bitcoin scammers to send tweets via the compromised accounts that asked the followers to send bitcoin to a given public address, with the promise to double their money. Within a few hours, Twitter disabled tweeting and reset passwords from all verified accounts. Analysis of the event revealed that the scammers had used social engineering to obtain credentials from Twitter employees to access an administration tool used by Twitter to view and change these accounts' personal details as to gain access as part of a "smash and grab" attempt to make money quickly, with an estimated US$120,000 in bitcoin deposited in various accounts before Twitter intervened. Several law enforcement entities including the FBI launched investigations into the attack. On August 5, 2022, Twitter disclosed that a bug introduced in a June 2021 update to the service allowed threat actors to link email addresses and phone numbers to twitter user's accounts. The bug was reported through Twitter's bug bounty program in January 2022 and subsequently fixed. While Twitter originally believed no one had taken advantage of the vulnerability, it was later revealed that a user on the online hacking forum Breach Forums had used the vulnerability to compile a list of over 5.4 million user profiles, which they offered to sell for $30,000. The information compiled by the hacker includes user's screen names, location and email addresses which could be used in phishing attacks or used to deanonymize accounts running under pseudonyms. During an outage, Twitter users were at one time shown the "fail whale" error message image created by Yiying Lu, illustrating eight orange birds using a net to hoist a whale from the ocean captioned "Too many tweets! Please wait a moment and try again." Web designer and Twitter user Jen Simmons was the first to coin the term "fail whale" in a September 2007 tweet. In a November 2013 Wired interview Chris Fry, VP of Engineering at that time, noted that the company had taken the "fail whale" out of use as the platform was now more stable. Twitter had approximately 98% uptime in 2007 (or about six full days of downtime). The downtime was particularly noticeable during events popular with the technology industry such as the 2008 Macworld Conference & Expo keynote address. As of January 16, 2026, Twitter's error message during an outage is "Something went wrong, but don't fret – Let's give it another shot." User accounts In June 2009, after being criticized by Kanye West and sued by Tony La Russa over unauthorized accounts run by impersonators, the company launched their "Verified Accounts" program. Twitter stated that an account with a "blue tick" verification badge indicates "we've been in contact with the person or entity the account is representing and verified that it is approved". In July 2016, Twitter announced a public application process to grant verified status to an account "if it is determined to be of public interest" and that verification "does not imply an endorsement". Verified status allows access to some features unavailable to other users, such as only seeing mentions from other verified accounts. In November 2020, Twitter announced a relaunch of its verification system in 2021. According to the new policy, Twitter verifies six different types of accounts; for three of them (companies, brands, and influential individuals like activists), the existence of a Wikipedia page will be one criterion for showing that the account has "Off Twitter Notability". Twitter states that it will re-open public verification applications at some point in "early 2021". In October 2022, after the takeover of Twitter by Elon Musk, it was reported that verification would instead be included in the paid Twitter Blue service, and that existing verified accounts would lose their status if they do not subscribe. On November 1, Musk confirmed that verification would be included in Blue in the future, dismissing the existing verification system as a "lords & peasants system". After concerns over the possibility of impersonation, Twitter subsequently reimplemented a second "Official" marker, consisting of a grey tick and "Official" text displayed under the username, for high-profile accounts of "government and commercial entities". In December 2022, the "Official" text was replaced by a gold checkmark for organizations, as well as a grey check mark for government and multilateral accounts. In March 2023, the gold check mark was made available for organizations to purchase through the Verified Organizations program (formerly called Twitter Blue for Business). Tweets are public, but users can also send private "direct messages". Information about who has chosen to follow an account and who a user has chosen to follow is also public, though accounts can be changed to "protected" which limits this information (and all tweets) to approved followers. Twitter collects personally identifiable information about its users and shares it with third parties as specified in its privacy policy. The service also reserves the right to sell this information as an asset if the company changes hands.[non-primary source needed] Advertisers can target users based on their history of tweets and may quote tweets in ads directed specifically to the user. Twitter launched the beta version of their "Verified Accounts" service on June 11, 2009, allowing people with public profiles to announce their account name. The profile pages of these accounts display a badge indicating their status. On December 14, 2010, the United States Department of Justice issued a subpoena directing Twitter to provide information for accounts registered to or associated with WikiLeaks. Twitter decided to notify its users and said, "... it's our policy to notify users about law enforcement and governmental requests for their information, unless we are prevented by law from doing so." In May 2011, a claimant known as "CTB" in the case of CTB v Twitter Inc. took action against Twitter at the High Court of Justice of England and Wales, requesting that the company release details of account holders. This followed gossip posted on Twitter about professional footballer Ryan Giggs's private life. This led to the 2011 British privacy injunctions controversy and the "super-injunction". Tony Wang, the head of Twitter in Europe, said that people who do "bad things" on the site would need to defend themselves under the laws of their own jurisdiction in the event of controversy and that the site would hand over information about users to the authorities when it was legally required to do so. He also suggested that Twitter would accede to a UK court order to divulge names of users responsible for "illegal activity" on the site. Twitter acquired Dasient, a startup that offers malware protection for businesses, in January 2012. Twitter announced plans to use Dasient to help remove hateful advertisers on the website. Twitter also offered a feature which would allow tweets to be removed selectively by country, before deleted tweets used to be removed in all countries. The first use of the policy was to block the account of German neo-Nazi group Besseres Hannover on October 18, 2012. The policy was used again the following day to remove anti-Semitic French tweets with the hashtag #unbonjuif ("a good Jew"). After the sharing of images showing the killing of American journalist James Foley in 2014, Twitter said that in certain cases it would delete pictures of people who had died after requests from family members and "authorized individuals". In 2015, following updated terms of service and privacy policy, Twitter users outside the United States were legally served by the Ireland-based Twitter International Company instead of Twitter, Inc. The change made these users subject to Irish and European Union data protection laws. On April 8, 2020, Twitter announced that users outside of the European Economic Area or United Kingdom (thus subject to GDPR) will no longer be allowed to opt out of sharing "mobile app advertising measurements" to Twitter third-party partners. On October 9, 2020, Twitter took additional steps to counter misleading campaigns ahead of the 2020 US Election. Twitter's new temporary update encouraged users to "add their own commentary" before retweeting a tweet, by making 'quoting tweet' a mandatory feature instead of optional. The social network giant aimed at generating context and encouraging the circulation of more thoughtful content. After limited results, the company ended this experiment in December 2020. On May 25, 2022, Twitter was fined $150 million for collecting users' phone numbers and email addresses used for security and using them for targeted advertising, required to notify its users, and banned from profiting from "deceptively collected data". The Federal Trade Commission (FTC) and the Department of Justice stated that Twitter violated a 2011 agreement not to use personal security data for targeted advertising. In September 2024, the FTC released a report summarizing 9 company responses (including from X) to orders made by the agency pursuant to Section 6(b) of the Federal Trade Commission Act of 1914 to provide information about user and non-user data collection (including of children and teenagers) and data use by the companies that found that the companies' user and non-user data practices put individuals vulnerable to identity theft, stalking, unlawful discrimination, emotional distress and mental health issues, social stigma, and reputational harm. In August 2013, Twitter announced plans to introduce a "report abuse" button for all versions of the site following uproar, including a petition with 100,000 signatures, over Tweets that included rape and death threats to historian Mary Beard, feminist campaigner Caroline Criado-Perez and the member of parliament Stella Creasy. Twitter announced new reporting and blocking policies in December 2014, including a blocking mechanism devised by Randi Harper, a target of GamerGate. In February 2015, CEO Dick Costolo said he was 'frankly ashamed' at how poorly Twitter handled trolling and abuse, and admitted Twitter had lost users as a result. As per a research study conducted by IT for Change on abuse and misogynistic trolling on Twitter directed at Indian women in public-political life, women perceived to be ideologically left-leaning, dissenters, Muslim women, political dissenters, and political commentators and women from opposition parties received a disproportionate amount of abusive and hateful messages on Twitter. In 2016, Twitter announced the creation of the Twitter Trust & Safety Council to help "ensure that people feel safe expressing themselves on Twitter". The council's inaugural members included 50 organizations and individuals. The announcement of Twitter's "Trust & Safety Council" was met with objection from parts of its userbase. Critics accused the member organizations of being heavily skewed towards "the restriction of hate speech" and a Reason article expressed concern that "there's not a single uncompromising anti-censorship figure or group on the list". Twitter banned 7,000 accounts and limited 150,000 more that had ties to QAnon on July 21, 2020. The bans and limits came after QAnon-related accounts began harassing other users through practices of swarming or brigading, coordinated attacks on these individuals through multiple accounts in the weeks prior. Those accounts limited by Twitter will not appear in searches nor be promoted in other Twitter functions. Twitter said they will continue to ban or limit accounts as necessary, with their support account stating "We will permanently suspend accounts Tweeting about these topics that we know are engaged in violations of our multi-account policy, coordinating abuse around individual victims, or are attempting to evade a previous suspension". In September 2021, Twitter began beta testing a feature called Safety Mode. The functionality aims to limit unwelcome interactions through automated detection of negative engagements. If a user has Safety Mode enabled, authors of tweets that are identified by Twitter's technology as being harmful or exercising uninvited behavior will be temporarily unable to follow the account, send direct messages, or see tweets from the user with the enabled functionality during the temporary block period. Jarrod Doherty, senior product manager at Twitter, stated that the technology in place within Safety Mode assesses existing relationships to prevent blocking accounts that the user frequently interacts with. In January 2016, Twitter was sued by the widow of a U.S. man killed in the 2015 Amman shooting attack, claiming that allowing the Islamic State of Iraq and the Levant (ISIL) to continually use the platform, including direct messages in particular, constituted the provision of material support to a terrorist organization, which is illegal under U.S. federal law. Twitter disputed the claim, stating that "violent threats and the promotion of terrorism deserve no place on Twitter and, like other social networks, our rules make that clear". The lawsuit was dismissed by the United States District Court for the Northern District of California, upholding the Section 230 safe harbor, which dictates that the operators of an interactive computer service are not liable for the content published by its users. The lawsuit was revised in August 2016, providing comparisons to other telecommunications devices. The second amended complaint was dismissed by the district court, a decision affirmed on appeal to the U.S. Court of Appeals for the Ninth Circuit on January 31, 2018. Twitter suspended multiple parody accounts that satirized Russian politics in May 2016, sparking protests and raising questions about where the company stands on freedom of speech. Following public outcry, Twitter restored the accounts the next day without explaining why the accounts had been suspended. The same day, Twitter, along with Facebook, Google, and Microsoft, jointly agreed to a European Union code of conduct obligating them to review "[the] majority of valid notifications for removal of illegal hate speech" posted on their services within 24 hours. In August 2016, Twitter stated that it had banned 235,000 accounts over the past six months, bringing the overall number of suspended accounts to 360,000 accounts in the past year, for violating policies banning use of the platform to promote extremism. On May 10, 2019, Twitter announced that they suspended 166,513 accounts for promoting terrorism in the July–December 2018 period, saying there was a steady decrease in terrorist groups trying to use the platform owing to its "zero-tolerance policy enforcement". According to Vijaya Gadde, Legal, Policy and Trust and Safety Lead at Twitter, there was a reduction of 19% terror related tweets from the previous reporting period (January–June 2018). As of July 30, 2020, Twitter will block URLs in tweets that point to external websites that contain malicious content (such as malware and phishing content) as well as hate speech, speech encouraging violence, terrorism, child sexual exploitation, breaches of privacy, and other similar content that is already banned as part of the content of tweets on the site. Users that frequently point to such sites may have their accounts suspended. Twitter said this was to bring their policy in line to prevent users from bypassing their tweet content restrictions by simply linking to the banned content. After the onset of protests by Donald Trump's supporters across the US in January 2021, Twitter suspended more than 70,000 accounts, stating that they shared "harmful QAnon-associated content" at a large scale, and were "dedicated to the propagation of this conspiracy theory across the service". One of the accounts suspended was then-former-president Trump's account; in February 2025, X settled a lawsuit filed by Trump in response to his suspension paying Trump approximately $10 million. Between January and late July 2017, Twitter had identified and shut down over 7,000 fake accounts created by Iranian influence operations. In May 2018, in response to scrutiny over the misuse of Twitter by those seeking to maliciously influence elections, Twitter announced that it would partner with the nonprofit organization Ballotpedia to add special labels verifying the authenticity of political candidates running for election in the U.S. In December 2019, Twitter removed 5,929 accounts for violating their manipulation policies. The company investigated and attributed these accounts to a single state-run information operation, which originated in Saudi Arabia. The accounts were reported to be a part of a larger group of 88,000 accounts engaged in spammy behavior. However, Twitter did not disclose all of them as some could possibly be legitimate accounts taken over through hacking. In March 2021, Twitter suspended around 3,500 fake accounts that were running a campaign to influence the American audience, after the US intelligence officials concluded that the assassination of The Washington Post journalist Jamal Khashoggi was "approved" by the Saudi Crown Prince Mohammed bin Salman. These Saudi accounts were working in two languages, English and Arabic, to influence public opinion around the issue. Many accounts commented directly on the tweets of US-based media houses, including The Post, CNN, CBS News and The Los Angeles Times. Twitter was unable to identify the source of the influence campaign. As of 2022[update], the top four countries spreading state-linked Twitter misinformation are Russia, China, Iran and Saudi Arabia. In November 2025, X began displaying various information on user accounts for transparency such as location, history, and username changes to combat bots and other malicious accounts. Other X users and media commenters noted seeming inconsistencies between some prominent users’ claimed location or nationality and the newly displayed data, with experts claiming that these accounts were likely used for “rage farming” or as foreign influence operations. A bot is a computer program that can automatically tweet, retweet, and follow other accounts. Twitter's open application programming interface and the availability of cloud servers make it possible for bots to exist within the social networking site. Benign bots may generate creative content and relevant product updates, whereas malicious bots can make unpopular people seem popular, push irrelevant products on users, and spread misinformation, spam or slander. Bots amass significant influence and have been noted to sway elections, influence the stock market, appeal to the public, and attack governments. As of 2013[update], Twitter said there were 20 million fake accounts on Twitter, representing less than 5% of active users. A 2020 estimate put the figure at 15% of all accounts or around 48 million accounts. Society Twitter had been used for a variety of purposes in many industries and scenarios. For example, it has been used to organize protests, including the protests over the 2009 Moldovan election, the 2009 student protests in Austria, the 2009 Gaza–Israel conflict, the 2009 Iranian green revolution, the 2010 Toronto G20 protests, the 2010 Bolivarian Revolution, the 2010 Stuttgart 21 protests in Germany, the 2011 Egyptian Revolution, 2011 England riots, the 2011 United States Occupy movement, the 2011 anti-austerity movement in Spain, the 2011 Aganaktismenoi movements in Greece, the 2011 demonstration in Rome, the 2011 Wisconsin labor protests, the 2012 Gaza–Israel conflict, the 2013 protests in Brazil, and the 2013 Gezi Park protests in Turkey. The service was also used as a form of civil disobedience: In 2010, users expressed outrage over the Twitter joke trial by copying a controversial joke about bombing an airport and attaching the hashtag #IAmSpartacus, a reference to the film Spartacus (1960) and a sign of solidarity and support to a man controversially prosecuted after posting a tweet joking about bombing an airport if they canceled his flight. #IAmSpartacus became the number one trending topic on Twitter worldwide. Another case of civil disobedience happened in the 2011 British privacy injunction debate, where several celebrities who had taken out anonymized injunctions were identified by thousands of users in protest to traditional journalism being censored. According to documents leaked by Edward Snowden and published in July 2014, the United Kingdom's GCHQ has a tool named BIRDSONG for "automated posting of Twitter updates" and a tool named BIRDSTRIKE for "Twitter monitoring and profile collection". During the 2019–20 Hong Kong protests, Twitter suspended a core group of 1,000 "fake" accounts and an associated network of 200,000 accounts for operating a disinformation campaign that was linked to the Chinese government. On June 12, 2020, Twitter suspended over 7,000 accounts from Turkey because those accounts were fake profiles, designed to support the Turkish president, Recep Tayyip Erdoğan, and were managed by a central authority. Turkey's communication director said that the decision was illogical, biased, and politically motivated. Turkey blocked access to Twitter twice, once after voice recordings appeared on Twitter in which Erdoğan ordered his son to stash away millions of dollars and another time for 12 hours in the aftermath of the earthquake of February 2023, when Erdoğan blamed the people for a disinformation campaign as they criticized the Government for their lack of help. In May 2021, Twitter labeled one of the tweets by Sambit Patra, a spokesman of the local ruling party BJP in India, as "manipulated media", leading to Twitter's offices in Delhi and Gurgaon being raided by the local police. Later, the Indian government released a statement in July 2021 claiming Twitter has lost its liability protection concerning user-generated content. This was brought on by Twitter's failure to comply with the new IT rules introduced in 2021, with a filing stating that the company failed to appoint executives to govern user content on the platform. In 2025, X sued the Indian government for using the IT Act to block tweets and other content on its platform. According to a report by Reuters, the United States ran a propaganda campaign to spread disinformation about the Sinovac Chinese COVID-19 vaccine, including using fake social media accounts on Twitter to spread the disinformation that the Sinovac vaccine contained pork-derived ingredients and was therefore haram under Islamic law. The campaign primarily targeted people in the Philippines and used a social media hashtag for "China is the virus" in Tagalog. Twitter allows pornographic content as long as it is marked "sensitive" by uploaders, which puts it behind an interstice and hides it from minors. The "super-follow" feature is said to enable competition with the subscription site OnlyFans, used mainly by sex workers. Many performers use Twitter's service to market and grow their porn businesses, attracting users to paywalled services like OnlyFans by distributing photos and short video clips as advertisements. In April 2022, Twitter convened a "Red Team" for the project of ACM, "Adult Content Monetization", as it is known internally. Eventually, the project was abandoned, because of the difficulty of implementing Real ID. A February 2021 report from the company's Health team begins, "While the amount of CSE (child sexual exploitation) online has grown exponentially, Twitter's investment in technologies to detect and manage the growth has not." Until February 2022, the only way for users to flag illegal content was to flag it as "sensitive media", a broad category that left much of the worst material unprioritized for moderation. In a February report, employees wrote that Twitter, along with other Tech Companies have "accelerated the pace of CSE content creation and distribution to a breaking point where manual detection, review, and investigations no longer scale" by allowing pornography and failing to invest in systems that could effectively monitor it. The working group made several recommendations, but they were not taken up and the group was disbanded. As part of its efforts to monetize porn, Twitter held an internal investigation which reported in April 2022, "Twitter cannot accurately detect child sexual exploitation and non-consensual nudity at scale." John Doe et al. v. Twitter, a civil lawsuit filed in the 9th Circuit Court, alleges that Twitter benefited from sex trafficking and refused to remove the illegal tweets when first informed of them. In an amicus brief filed in the case, the NCMEC said, "The children informed the company that they were minors, that they had been 'baited, harassed, and threatened' into making the videos, that they were victims of 'sex abuse' under investigation by law enforcement" but Twitter failed to remove the videos, "allowing them to be viewed by hundreds of thousands of the platform's users". Some major brands, including Dyson, Mazda, Forbes, and PBS Kids suspended their marketing campaigns and pulled their ads from the platform after an investigation showed that Twitter failed to suspend 70% of the accounts that shared or solicited the prohibited content. In December 2025, social media users reported that X's integrated chatbot, Grok, would allow users to noncensually strip individuals, including minors, or show them performing sexually explicit and pornographic acts. The majority of these prompts were targeted at women and girls. Images generated by Grok since December 2025 have been disproportionately of people in bikinis, transparent clothes, and the like, with users being able to generate such images through prompts such as "put her in a bikini". This scandal would lead to significant criticism from lawmakers across the world, calls for bans on X, as well as legal crackdowns on X and xAI for, amongst other reasons, the facilitation of sexual abuse, revenge porn, and child pornography. A practical use for Twitter's real-time functionality is as an effective de facto emergency communication system for breaking news. It was neither intended nor designed for high-performance communication, but the idea that it could be used for emergency communication was not lost on the creators, who knew that the service could have wide-reaching effects early on when the company used it to communicate during earthquakes. Another practical use that is being studied is Twitter's ability to track epidemics and how they spread. Additionally Twitter serves as a real-time sensor for natural disasters such as bushfires and earthquakes. Twitter has been adopted as a communication and learning tool in educational and research settings mostly in colleges and universities. It has been used as a backchannel to promote student interactions, especially in large-lecture courses. Research has found that using Twitter in college courses helps students communicate with each other and faculty, promotes informal learning, allows shy students a forum for increased participation, increases student engagement, and improves overall course grades. Twitter has been an increasingly growing in the field of education as an effective tool that can be used to encourage learning and idea, or knowledge sharing, in and outside the classroom. By using or creating hashtags, students and educators are able to communicate under specific categories of their choice to enhance and promote education. A broad example of a hashtag used in education is "edchat", to communicate with other teachers and people using that hashtag. Once teachers find someone they want to talk to, they can either direct message the person or narrow down the hashtag to make the topic of the conversation more specific, using hashtags for scichat (science), engchat (English), sschat (social studies). Jonathan Zittrain, professor of Internet law at Harvard Law School, said that "the qualities that make Twitter seem inane and half-baked are what makes it so powerful." In that same vein, and with Sigmund Freud in mind, political communications expert Matthew Auer observed that well-crafted tweets by public figures often deliberately mix trivial and serious information so as to appeal to all three parts of the reader's personality: the id, ego, and superego. The poets Mira Gonzalez and Tao Lin published a book titled Selected Tweets featuring selections of their tweets over some eight years. The novelist Rick Moody wrote a short story for Electric Literature called "Some Contemporary Characters", composed entirely of tweets. Many commentators have suggested that Twitter radically changed the format of reporting due to instant, short, and frequent communication. According to The Atlantic writers Benjamin M. Reilly and Robinson Meyer, Twitter has an outsized impact on the public discourse and media. "Something happens on Twitter; celebrities, politicians and journalists talk about it, and it's circulated to a wider audience by Twitter's algorithms; journalists write about the dustup." This can lead to an argument on a Twitter feed looking like a "debate roiling the country... regular people are left with a confused, agitated view of our current political discourse". In a 2018 article in the Columbia Journalism Review, Matthew Ingram argued much the same about Twitter's "oversized role" and that it promotes immediacy over newsworthiness. In some cases, inauthentic and provocative tweets were taken up as common opinion in mainstream articles. Writers in several outlets unintentionally cited the opinions of Russian Internet Research Agency-affiliated accounts. World leaders and their diplomats have taken note of Twitter's rapid expansion and have been increasingly using Twitter diplomacy, the use of Twitter to engage with foreign publics and their own citizens. US Ambassador to Russia, Michael A. McFaul has been attributed as a pioneer of international Twitter diplomacy. He used Twitter after becoming ambassador in 2011, posting in English and Russian. On October 24, 2014, Queen Elizabeth II sent her first tweet to mark the opening of the London Science Museum's Information Age exhibition. A 2013 study by website Twiplomacy found that 153 of the 193 countries represented at the United Nations had established government Twitter accounts. The same study also found that those accounts amounted to 505 Twitter handles used by world leaders and their foreign ministers, with their tweets able to reach a combined audience of over 106 million followers. According to an analysis of accounts, the heads of state of 125 countries and 139 other leading politicians have Twitter accounts that have between them sent more than 350,000 tweets and have almost 52 million followers. However, only 30 of these do their own tweeting, more than 80 do not subscribe to other politicians and many do not follow any accounts. The Twitter account for the pope was set up in 2012. As of February 2025[update], it has 18 million followers (@Pontifex). Twitter is banned completely in Russia, Iran, China and North Korea, and has been intermittently blocked in numerous countries, including Egypt, Iraq, Nigeria, Turkey, Venezuela and Turkmenistan, on different basis. In 2016, Twitter cooperated with the Israeli government to remove certain content originating outside Israel from tweets seen in Israel. In the 11th biannual transparency report published on September 19, 2017, Twitter said that Turkey was the first among countries where about 90% of removal requests came from, followed by Russia, France and Germany. Twitter stated that between July 1 and December 31, 2018, "We received legal demands relating to 27,283 accounts from 47 different countries, including Bulgaria, Kyrgyzstan, Macedonia, and Slovenia for the first time." As part of evidence to a U.S. Senate Enquiry, the company admitted that their systems "detected and hid" several hundred thousand tweets relating to the 2016 Democratic National Committee email leak. During the curfew in Jammu and Kashmir after revocation of its autonomous status on August 5, 2019, the Indian government approached Twitter to block accounts accused of spreading anti-India content; by October 25, nearly one million tweets had been removed as a result. In March 2022, shortly after Russia's censorship of Twitter, a Tor onion service link was created by the platform to allow people to access the website, even in countries with heavy Internet censorship. In 2025, India ordered X to block 8,000 accounts to users within India, under threat of fines. X criticized the government's orders and encouraged affected users to seek legal recourse. X uses Age Verify with ID or Photo Selfie for users to access sensitive content like pornography in the UK, EU and EEA to comply with Online Safety Act 2023 and EU's Digital Service. Twitter removed more than 88,000 propaganda accounts linked to Saudi Arabia. Twitter removed tweets from accounts associated with the Russian Internet Research Agency that had tried to influence public opinion during and after the 2016 US election. In June 2020, Twitter also removed 175,000 propaganda accounts that were spreading biased political narratives for the Chinese Communist Party, the United Russia Party, or Turkey's President Erdogan, identified based on centralized behavior. Twitter also removed accounts linked to the governments of Armenia, Egypt, Cuba, Serbia, Honduras, Indonesia and Iran. Twitter suspended Pakistani accounts tied to government officials for posting tweets about the Kashmir conflict between India and Pakistan. In February 2021, Twitter removed accounts in India that criticized Prime Minister Narendra Modi's government for its conduct during Indian farmers' protests in 2020–2021. At the start of the 2020 COVID-19 pandemic, numerous tweets reported false medical information related to the pandemic. Twitter announced a new policy in which they would label tweets containing misinformation going forward. In April 2020, Twitter removed accounts which defended President Rodrigo Duterte's response to the spread of COVID-19 in the Philippines. In November 2020, then Chief Technology Officer and future CEO of Twitter Parag Agrawal, when asked by MIT Technology Review about balancing the protection of free speech as a core value and the endeavour to combat misinformation, said: "Our role is not to be bound by the First Amendment, but our role is to serve a healthy public conversation ... focus less on thinking about free speech, but thinking about how the times have changed." Musk had been critical of Twitter's moderation of misinformation prior to his acquisition of the company. After the transition, Musk eliminated the misinformation moderation team, and stopped enforcing its policy on labeling tweets with misleading information about coronavirus. While Twitter had joined a voluntary program under the European Union's to fight disinformation in June 2022, Musk pulled the company out of the program in May 2023. In August 2020, development of Birdwatch was announced, initially described as a moderation tool. Twitter first launched the Birdwatch program in January 2021, intended as a way to debunk misinformation and propaganda, with a pilot program of 1,000 contributors, weeks after the January 6 United States Capitol attack. The aim was to "build Birdwatch in the open, and have it shaped by the Twitter community". In November 2021, Twitter updated the Birdwatch moderation tool to limit the visibility of contributors' identities by creating aliases for their accounts, in an attempt to limit bias towards the author of notes. Twitter then expanded access to notes made by the Birdwatch contributors in March 2022, giving a randomized set of US users the ability to view notes attached to tweets and rate them, with a pilot of 10,000 contributors. On average, contributors were noting 43 times a day in 2022 prior to the Russian invasion of Ukraine. This then increased to 156 on the day of the invasion, estimated to be a very small portion of the misleading posts on the platform. By March 1, only 359 of 10,000 contributors had proposed notes in 2022, while a Twitter spokeswoman described plans to scale up the program, with the focus on "ensuring that Birdwatch is something people find helpful and can help inform understanding". By September 2022, the program had expanded to 15,000 users. In October 2022, the most commonly published notes were related to COVID-19 misinformation based on historical usage. In November 2022, at the request of new owner Elon Musk, Birdwatch was rebranded to Community Notes, taking an open-source approach to deal with misinformation, and expanded to Europe and countries outside of the US. Twitter Inc. v. Taamneh, alongside Gonzalez v. Google, were heard by the United States Supreme Court during its 2022–2023 term. Both cases dealt with Internet content providers and whether they are liable for terrorism-related information posted by their users. In the case of Twitter v. Taamneh, the case asked if Twitter and other social media services are liable for user-generated terrorism content under the Antiterrorism and Effective Death Penalty Act of 1996 and are beyond their Section 230 protections. The court ruled in May 2023 that the charges brought against Twitter and other companies were not permissible under the Antiterrorism Act, and did not address the Section 230 question. This decision also supported the Court's per curiam decision in Gonzalez returning that case to the lower court for review in light of the Twitter decision. In 2016, Twitter shareholder Doris Shenwick filed a lawsuit against Twitter, Inc., claiming executives misled investors over the company's growth prospects. In 2021, Twitter agreed to pay $809.5 million to settle. In May 2022, Twitter agreed to pay $150 million to settle a lawsuit started by the Department of Justice and the Federal Trade Commission. The lawsuit concerned Twitter's use of email addresses and phone numbers of Twitter users to target advertisements at them. The company also agreed to third-party audits of its data privacy program. On November 3, 2022, on the eve of expected layoffs, a group of Twitter employees based in San Francisco and Cambridge filed a lawsuit in the U.S. District Court in San Francisco. Naming five current or former workers as plaintiffs, the suit accused the company of violating federal and state laws that govern notice of employment termination. The federal law in question is the Worker Adjustment and Retraining Notification (WARN) Act, and the state law in question is California's state WARN Act. On November 20, 2023, X filed a lawsuit against Media Matters, a media watchdog group. The lawsuit alleges defamation by Media Matters following its publication of a report claiming that advertisements for major brands were displayed alongside posts promoting Adolf Hitler and the Nazi Party. On August 6, 2024, X filed an antitrust lawsuit in the Northern District of Texas against the World Federation of Advertisers, Unilever, Mars, CVS and Ørsted, alleging that the advertisers had conspired via their participation in the Global Alliance for Responsible Media to withhold "billions of dollars in advertising revenue" from the platform. The World Federation Of Advertisers created the Global Alliance for Responsible Media in 2019 to address "illegal or harmful content on digital media platforms and its monetization via advertising". On August 13, 2024, the Workplace Relations Commission ordered X to pay €550,000 to former senior staffer Gary Rooney in an unfair dismissal case. X had argued that Rooney's failure to check "yes" at the bottom of an email from Elon Musk constituted resignation. Criticism The platform has faced significant controversy since its buying by Musk and re-branding to X, including an increase in misinformation, hate speech and antisemitism. According to a report published by the "Never Again" Association, X refuses to remove hate speech or ignores reports. Researchers have called for greater transparency especially ahead of national elections, based on findings that the platform algorithm favors a small number of popular accounts, in particular right-leaning users. In July 2025, Musk and xAI's artificial intelligence tool, Grok, faced backlash from X users and the Anti-Defamation League regarding a series of antisemitic tweets made in response to the July 2025 Central Texas floods. The Grok account acknowledged the "inappropriate" posts and removed the comments. The incident is reported to have happened just days after Musk announced updates to Grok, noting that users should see "a difference when you ask Grok questions." Statistics As of May 2025[update], the ten X accounts with the most followers were: The "Oscar Selfie" orchestrated by 86th Academy Awards host Ellen DeGeneres during the March 2, 2014, broadcast was, at the time, the most retweeted image ever. The photo of twelve celebrities broke the previous retweet record within forty minutes and was retweeted over 1.8 million times in the first hour. On May 9, 2017, Ellen's record was broken by Carter Wilkerson (@carterjwm) by collecting nearly 3.5 million retweets in a little over a month. This record was broken when Yusaku Maezawa announced a giveaway on Twitter in January 2019, accumulating 4.4 million retweets. A similar tweet he made in December 2019 was retweeted 3.8 million times. The most tweeted moment in the history of Twitter occurred on August 2, 2013; during a Japanese television airing of the Studio Ghibli film Castle in the Sky, fans simultaneously tweeted the word balse (バルス)—the incantation for a destruction spell used during its climax, after it was uttered in the film. There was a global peak of 143,199 tweets in one second, beating the previous record of 33,388. The most discussed event in Twitter history occurred on October 24, 2015; the hashtag ("#ALDubEBTamangPanahon") for Tamang Panahon, a live special episode of the Filipino variety show Eat Bulaga! at the Philippine Arena, centering on its popular on-air couple AlDub, attracted 41 million tweets.[non-primary source needed] The most-discussed sporting event in Twitter history was the 2014 FIFA World Cup semi-final between Brazil and Germany on July 8, 2014. According to Guinness World Records, the fastest pace to a million followers was set by actor Robert Downey Jr. in 23 hours and 22 minutes in April 2014. This record was later broken by Caitlyn Jenner, who joined the site on June 1, 2015, and amassed a million followers in just 4 hours and 3 minutes.

Contents PyGTK PyGTK is a set of Python wrappers for the GTK graphical user interface library. PyGTK is free software and licensed under the LGPL. It is analogous to PyQt/PySide and wxPython, the Python wrappers for Qt and wxWidgets, respectively. Its original author is GNOME developer James Henstridge. There are six people in the core development team, with various other people who have submitted patches and bug reports. PyGTK has been selected as the environment of choice for applications running on One Laptop Per Child systems. PyGTK was phased out with the transition to GTK version 3 and be replaced with PyGObject, which uses GObject Introspection to generate bindings for Python and other languages on the fly. This is expected to eliminate the delay between GTK updates and corresponding language binding updates, as well as reduce maintenance burden on the developers. Syntax The Python code below will produce a 200x200 pixel window with the words "Hello World" inside. PyGTK has been used in a number of notable applications, some examples: PyGObject PyGObject provides a wrapper for use in Python programs when accessing GObject libraries. GObject is an object system used by GTK, GLib, GIO, GStreamer and other libraries. Like the GObject library itself, PyGObject is licensed under the GNU LGPL, so it is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single-purpose scripts to large full-featured applications. PyGObject can dynamically access any GObject libraries that use GObject Introspection. It replaces the need for separate modules such as PyGTK, GIO and python-gnome to build a full GNOME 3.0 application. Once new functionality is added to GObject library it is instantly available as a Python API without the need for intermediate Python glue. PyGObject has replaced PyGTK, but it has taken a considerable amount of time for many programs to be ported. Most of the software listed here has an older version which used PyGTK.

Contents OpenAI OpenAI is an American artificial intelligence research organization comprising both a non-profit foundation and a controlled for-profit public benefit corporation (PBC), headquartered in San Francisco. It aims to develop "safe and beneficial" artificial general intelligence (AGI), which it defines as "highly autonomous systems that outperform humans at most economically valuable work". OpenAI is widely recognized for its development of the GPT family of large language models, the DALL-E series of text-to-image models, and the Sora series of text-to-video models, which have influenced industry research and commercial applications. Its release of ChatGPT in November 2022 has been credited with catalyzing widespread interest in generative AI. The organization was founded in 2015 in Delaware but evolved a complex corporate structure. As of October 2025, following restructuring approved by California and Delaware regulators, the non-profit OpenAI Foundation holds 26% of the for-profit OpenAI Group PBC, with Microsoft holding 27% and employees/other investors holding 47%. Under its governance arrangements, the OpenAI Foundation holds the authority to appoint the board of the for-profit OpenAI Group PBC, a mechanism designed to align the entity’s strategic direction with the Foundation’s charter. Microsoft previously invested over $13 billion into OpenAI, and provides Azure cloud computing resources. In October 2025, OpenAI conducted a $6.6 billion share sale that valued the company at $500 billion. In 2023 and 2024, OpenAI faced multiple lawsuits for alleged copyright infringement against authors and media companies whose work was used to train some of OpenAI's products. In November 2023, OpenAI's board removed Sam Altman as CEO, citing a lack of confidence in him, but reinstated him five days later following a reconstruction of the board. Throughout 2024, roughly half of then-employed AI safety researchers left OpenAI, citing the company's prominent role in an industry-wide problem. Founding In December 2015, OpenAI was founded as a not for profit organization by Sam Altman, Elon Musk, Ilya Sutskever, Greg Brockman, Trevor Blackwell, Vicki Cheung, Andrej Karpathy, Durk Kingma, John Schulman, Pamela Vagata, and Wojciech Zaremba, with Sam Altman and Elon Musk as the co-chairs. A total of $1 billion in capital was pledged by Sam Altman, Greg Brockman, Elon Musk, Reid Hoffman, Jessica Livingston, Peter Thiel, Amazon Web Services (AWS), and Infosys. However, the actual capital collected significantly lagged pledges. According to company disclosures, only $130 million had been received by 2019. In its founding charter, OpenAI stated an intention to collaborate openly with other institutions by making certain patents and research publicly available, but later restricted access to its most capable models, citing competitive and safety concerns. OpenAI was initially run from Brockman's living room. It was later headquartered at the Pioneer Building in the Mission District, San Francisco. According to OpenAI's charter, its founding mission is "to ensure that artificial general intelligence (AGI)—by which we mean highly autonomous systems that outperform humans at most economically valuable work—benefits all of humanity." Musk and Altman stated in 2015 that they were partly motivated by concerns about AI safety and existential risk from artificial general intelligence. OpenAI stated that "it's hard to fathom how much human-level AI could benefit society", and that it is equally difficult to comprehend "how much it could damage society if built or used incorrectly". The startup also wrote that AI "should be an extension of individual human wills and, in the spirit of liberty, as broadly and evenly distributed as possible", and that "because of AI's surprising history, it's hard to predict when human-level AI might come within reach. When it does, it'll be important to have a leading research institution which can prioritize a good outcome for all over its own self-interest." Co-chair Sam Altman expected a decades-long project that eventually surpasses human intelligence. Brockman met with Yoshua Bengio, one of the "founding fathers" of deep learning, and drew up a list of great AI researchers. Brockman was able to hire nine of them as the first employees in December 2015. OpenAI did not pay AI researchers salaries comparable to those of Facebook or Google. It also did not pay stock options which AI researchers typically get. Nevertheless, OpenAI spent $7 million on its first 52 employees in 2016. OpenAI's potential and mission drew these researchers to the firm; a Google employee said he was willing to leave Google for OpenAI "partly because of the very strong group of people and, to a very large extent, because of its mission." OpenAI co-founder Wojciech Zaremba stated that he turned down "borderline crazy" offers of two to three times his market value to join OpenAI instead. In April 2016, OpenAI released a public beta of "OpenAI Gym", its platform for reinforcement learning research. Nvidia gifted its first DGX-1 supercomputer to OpenAI in August 2016 to help it train larger and more complex AI models with the capability of reducing processing time from six days to two hours. In December 2016, OpenAI released "Universe", a software platform for measuring and training an AI's general intelligence across the world's supply of games, websites, and other applications. Corporate structure In 2019, OpenAI transitioned from non-profit to "capped" for-profit, with the profit being capped at 100 times any investment. According to OpenAI, the capped-profit model allows OpenAI Global, LLC to legally attract investment from venture funds and, in addition, to grant employees stakes in the company. Many top researchers work for Google Brain, DeepMind, or Facebook, which offer equity that a nonprofit would be unable to match. Before the transition, OpenAI was legally required to publicly disclose the compensation of its top employees. The company then distributed equity to its employees and partnered with Microsoft, announcing an investment package of $1 billion into the company. Since then, OpenAI systems have run on an Azure-based supercomputing platform from Microsoft. OpenAI Global, LLC then announced its intention to commercially license its technologies. It planned to spend $1 billion "within five years, and possibly much faster". Altman stated that even a billion dollars may turn out to be insufficient, and that the lab may ultimately need "more capital than any non-profit has ever raised" to achieve artificial general intelligence. The nonprofit, OpenAI, Inc., is the sole controlling shareholder of OpenAI Global, LLC, which, despite being a for-profit company, retains a formal fiduciary responsibility to OpenAI, Inc.'s nonprofit charter. A majority of OpenAI, Inc.'s board is barred from having financial stakes in OpenAI Global, LLC. In addition, minority members with a stake in OpenAI Global, LLC are barred from certain votes due to conflict of interest. Some researchers have argued that OpenAI Global, LLC's switch to for-profit status is inconsistent with OpenAI's claims to be "democratizing" AI. On February 29, 2024, Elon Musk filed a lawsuit against OpenAI and CEO Sam Altman, accusing them of shifting focus from public benefit to profit maximization—a case OpenAI dismissed as "incoherent" and "frivolous," though Musk later revived legal action against Altman and others in August. On April 9, 2024, OpenAI countersued Musk in federal court, alleging that he had engaged in "bad-faith tactics" to slow the company's progress and seize its innovations for his personal benefit. OpenAI also argued that Musk had previously supported the creation of a for-profit structure and had expressed interest in controlling OpenAI himself. The countersuit seeks damages and legal measures to prevent further alleged interference. On February 10, 2025, a consortium of investors led by Elon Musk submitted a $97.4 billion unsolicited bid to buy the nonprofit that controls OpenAI, declaring willingness to match or exceed any better offer. The offer was rejected on 14 February 2025, with OpenAI stating that it was not for sale, but the offer complicated Altman's restructuring plan by suggesting a lower bar for how much the nonprofit should be valued. OpenAI, Inc. was originally designed as a nonprofit in order to ensure that AGI "benefits all of humanity" rather than "the private gain of any person". In 2019, it created OpenAI Global, LLC, a capped-profit subsidiary controlled by the nonprofit. In December 2024, OpenAI proposed a restructuring plan to convert the capped-profit into a Delaware-based public benefit corporation (PBC), and to release it from the control of the nonprofit. The nonprofit would sell its control and other assets, getting equity in return, and would use it to fund and pursue separate charitable projects, including in science and education. OpenAI's leadership described the change as necessary to secure additional investments, and claimed that the nonprofit's founding mission to ensure AGI "benefits all of humanity" would be better fulfilled. The plan has been criticized by former employees. A legal letter named "Not For Private Gain" asked the attorneys general of California and Delaware to intervene, stating that the restructuring is illegal and would remove governance safeguards from the nonprofit and the attorneys general. The letter argues that OpenAI's complex structure was deliberately designed to remain accountable to its mission, without the conflicting pressure of maximizing profits. It contends that the nonprofit is best positioned to advance its mission of ensuring AGI benefits all of humanity by continuing to control OpenAI Global, LLC, whatever the amount of equity that it could get in exchange. PBCs can choose how they balance their mission with profit-making. Controlling shareholders have a large influence on how closely a PBC sticks to its mission. On October 28, 2025, OpenAI announced that it had adopted the new PBC corporate structure after receiving approval from the attorneys general of California and Delaware. Under the new structure, OpenAI's for-profit branch became a public benefit corporation known as OpenAI Group PBC, while the non-profit was renamed to the OpenAI Foundation. The OpenAI Foundation holds a 26% stake in the PBC, while Microsoft holds a 27% stake and the remaining 47% is owned by employees and other investors. All members of the OpenAI Group PBC board of directors will be appointed by the OpenAI Foundation, which can remove them at any time. Members of the Foundation's board will also serve on the for-profit board. The new structure allows the for-profit PBC to raise investor funds like most traditional tech companies, including through an initial public offering, which Altman claimed was the most likely path forward. In January 2023, OpenAI Global, LLC was in talks for funding that would value the company at $29 billion, double its 2021 value. On January 23, 2023, Microsoft announced a new US$10 billion investment in OpenAI Global, LLC over multiple years, partially needed to use Microsoft's cloud-computing service Azure. From September to December, 2023, Microsoft rebranded all variants of its Copilot to Microsoft Copilot, and they added MS-Copilot to many installations of Windows and released Microsoft Copilot mobile apps. Following OpenAI's 2025 restructuring, Microsoft owns a 27% stake in the for-profit OpenAI Group PBC, valued at $135 billion. In a deal announced the same day, OpenAI agreed to purchase $250 billion of Azure services, with Microsoft ceding their right of first refusal over OpenAI's future cloud computing purchases. As part of the deal, OpenAI will continue to share 20% of its revenue with Microsoft until it achieves AGI, which must now be verified by an independent panel of experts. The deal also loosened restrictions on both companies working with third parties, allowing Microsoft to pursue AGI independently and allowing OpenAI to develop products with other companies. In 2017, OpenAI spent $7.9 million, a quarter of its functional expenses, on cloud computing alone. In comparison, DeepMind's total expenses in 2017 were $442 million. In the summer of 2018, training OpenAI's Dota 2 bots required renting 128,000 CPUs and 256 GPUs from Google for multiple weeks. In October 2024, OpenAI completed a $6.6 billion capital raise with a $157 billion valuation including investments from Microsoft, Nvidia, and SoftBank. On January 21, 2025, Donald Trump announced The Stargate Project, a joint venture between OpenAI, Oracle, SoftBank and MGX to build an AI infrastructure system in conjunction with the US government. The project takes its name from OpenAI's existing "Stargate" supercomputer project and is estimated to cost $500 billion. The partners planned to fund the project over the next four years. In July, the United States Department of Defense announced that OpenAI had received a $200 million contract for AI in the military, along with Anthropic, Google, and xAI. In the same month, the company made a deal with the UK Government to use ChatGPT and other AI tools in public services. OpenAI subsequently began a $50 million fund to support nonprofit and community organizations. In April 2025, OpenAI raised $40 billion at a $300 billion post-money valuation, which was the highest-value private technology deal in history. The financing round was led by SoftBank, with other participants including Microsoft, Coatue, Altimeter and Thrive. In July 2025, the company reported annualized revenue of $12 billion. This was an increase from $3.7 billion in 2024, which was driven by ChatGPT subscriptions, which reached 20 million paid subscribers by April 2025, up from 15.5 million at the end of 2024, alongside a rapidly expanding enterprise customer base that grew to five million business users. The company’s cash burn remains high because of the intensive computational costs required to train and operate large language models. It projects an $8 billion operating loss in 2025. OpenAI reports revised long-term spending projections totaling approximately $115 billion through 2029, with annual expenditures projected to escalate significantly, reaching $17 billion in 2026, $35 billion in 2027, and $45 billion in 2028. These expenditures are primarily allocated toward expanding compute infrastructure, developing proprietary AI chips, constructing data centers, and funding intensive model training programs, with more than half of the spending through the end of the decade expected to support research-intensive compute for model training and development. The company's financial strategy prioritizes market expansion and technological advancement over near-term profitability, with OpenAI targeting cash-flow-positive operations by 2029 and projecting revenue of approximately $200 billion by 2030. This aggressive spending trajectory underscores both the enormous capital requirements of scaling cutting-edge AI technology and OpenAI's commitment to maintaining its position as a leader in the artificial intelligence industry. In October 2025, OpenAI completed an employee share sale of up to $10 billion to existing investors which valued the company at $500 billion. The deal values OpenAI as the most valuable privately owned company in the world—surpassing SpaceX as the world's most valuable private company. On November 17, 2023, Sam Altman was removed as CEO when its board of directors (composed of Helen Toner, Ilya Sutskever, Adam D'Angelo and Tasha McCauley) cited a lack of confidence in him. Chief Technology Officer Mira Murati took over as interim CEO. Greg Brockman, the president of OpenAI, was also removed as chairman of the board and resigned from the company's presidency shortly thereafter. Three senior OpenAI researchers subsequently resigned: director of research and GPT-4 lead Jakub Pachocki, head of AI risk Aleksander Mądry, and researcher Szymon Sidor. On November 18, 2023, there were reportedly talks of Altman returning as CEO amid pressure placed upon the board by investors such as Microsoft and Thrive Capital, who objected to Altman's departure. Although Altman himself spoke in favor of returning to OpenAI, he has since stated that he considered starting a new company and bringing former OpenAI employees with him if talks to reinstate him didn't work out. The board members agreed "in principle" to resign if Altman returned. On November 19, 2023, negotiations with Altman to return failed and Murati was replaced by Emmett Shear as interim CEO. The board initially contacted Anthropic CEO Dario Amodei (a former OpenAI executive) about replacing Altman, and proposed a merger of the two companies, but both offers were declined. On November 20, 2023, Microsoft CEO Satya Nadella announced Altman and Brockman would be joining Microsoft to lead a new advanced AI research team, but added that they were still committed to OpenAI despite recent events. Before the partnership with Microsoft was finalized, Altman gave the board another opportunity to negotiate with him. About 738 of OpenAI's 770 employees, including Murati and Sutskever, signed an open letter stating they would quit their jobs and join Microsoft if the board did not rehire Altman and then resign. This prompted OpenAI investors to consider legal action against the board as well. In response, OpenAI management sent an internal memo to employees stating that negotiations with Altman and the board had resumed and would take some time. On November 21, 2023, after continued negotiations, Altman and Brockman returned to the company in their prior roles along with a reconstructed board made up of new members Bret Taylor (as chairman) and Lawrence Summers, with D'Angelo remaining. According to subsequent reporting, shortly before Altman’s firing, some employees raised concerns to the board about how he had handled the safety implications of a recent internal AI capability discovery. On November 29, 2023, OpenAI announced that an anonymous Microsoft employee had joined the board as a non-voting member to observe the company's operations; Microsoft resigned from the board in July 2024. In February 2024, the Securities and Exchange Commission subpoenaed OpenAI's internal communication to determine if Altman's alleged lack of candor misled investors. In 2024, following the temporary removal of Sam Altman and his return, many employees gradually left OpenAI, including most of the original leadership team and a significant number of AI safety researchers. In August 2023, it was announced that OpenAI had acquired the New York-based start-up Global Illumination, a company that deploys AI to develop digital infrastructure and creative tools. In June 2024, OpenAI acquired Multi, a startup focused on remote collaboration. In March 2025, OpenAI reached a deal with CoreWeave to acquire $350 million worth of CoreWeave shares and access to AI infrastructure, in return for $11.9 billion paid over five years. Microsoft was already CoreWeave's biggest customer in 2024. Alongside their other business dealings, OpenAI and Microsoft were renegotiating the terms of their partnership to facilitate a potential future initial public offering by OpenAI, while ensuring Microsoft's continued access to advanced AI models. On May 21, OpenAI announced the $6.5 billion acquisition of io, an AI hardware start-up founded by former Apple designer Jony Ive in 2024. In September 2025, OpenAI agreed to acquire the product testing startup Statsig for $1.1 billion in an all-stock deal and appointed Statsig's founding CEO Vijaye Raji as OpenAI's chief technology officer of applications. The company also announced development of an AI-driven hiring service designed to rival LinkedIn. OpenAI acquired personal finance app Roi in October 2025. In October 2025, OpenAI acquired Software Applications Incorporated, the developer of Sky, a macOS-based natural language interface designed to operate across desktop applications. The Sky team joined OpenAI, and the company announced plans to integrate Sky’s capabilities into ChatGPT. In December 2025, it was announced OpenAI had agreed to acquire Neptune, an AI tooling startup that helps companies track and manage model training, for an undisclosed amount. In January 2026, it was announced OpenAI had acquired healthcare technology startup Torch for approximately $60 million. The acquisition followed the launch of OpenAI’s ChatGPT Health product and was intended to strengthen the company’s medical data and healthcare artificial intelligence capabilities. OpenAI has been criticized for outsourcing the annotation of data sets to Sama, a company based in San Francisco that employed workers in Kenya. These annotations were used to train an AI model to detect toxicity, which could then be used to moderate toxic content, notably from ChatGPT's training data and outputs. However, these pieces of text usually contained detailed descriptions of various types of violence, including sexual violence. The investigation uncovered that OpenAI began sending snippets of data to Sama as early as November 2021. The four Sama employees interviewed by Time described themselves as mentally scarred. OpenAI paid Sama $12.50 per hour of work, and Sama was redistributing the equivalent of between $1.32 and $2.00 per hour post-tax to its annotators. Sama's spokesperson said that the $12.50 was also covering other implicit costs, among which were infrastructure expenses, quality assurance and management. In 2024, OpenAI began collaborating with Broadcom to design a custom AI chip capable of both training and inference, targeted for mass production in 2026 and to be manufactured by TSMC on a 3 nm process node. This initiative intended to reduce OpenAI's dependence on Nvidia GPUs, which are costly and face high demand in the market. In January 2024, Arizona State University purchased ChatGPT Enterprise in OpenAI's first deal with a university. In June 2024, Apple Inc. signed a contract with OpenAI to integrate ChatGPT features into its products as part of its new Apple Intelligence initiative. In June 2025, OpenAI began renting Google Cloud's Tensor Processing Units (TPUs) to support ChatGPT and related services, marking its first meaningful use of non‑Nvidia AI chips. In September 2025, it was revealed that OpenAI signed a contract with Oracle to purchase $300 billion in computing power over the next five years. In September 2025, OpenAI and NVIDIA announced a memorandum of understanding that included a potential deployment of at least 10 gigawatts of NVIDIA systems and a $100 billion investment from NVIDIA in OpenAI. OpenAI expected the negotiations to be completed within weeks. As of January 2026, this has not been realized, and the two sides are rethinking the future of their partnership. In October 2025, OpenAI announced a multi-billion dollar deal with AMD. OpenAI committed to purchasing six gigawatts worth of AMD chips, starting with the MI450. OpenAI will have the option to buy up to 160 million shares of AMD, about 10% of the company, depending on development, performance and share price targets. In December 2025, Disney said it would make a $1 billion investment in OpenAI, and signed a three-year licensing deal that will let users generate videos using Sora—OpenAI's short-form AI video platform. More than 200 Disney, Marvel, Star Wars and Pixar characters will be available to OpenAI users. In early 2026, Amazon entered advanced discussions to invest up to $50 billion in OpenAI as part of a potential artificial intelligence partnership. Under the proposed agreement, OpenAI’s models could be integrated into Amazon’s digital assistant Alexa and other internal projects. OpenAI provides LLMs to the Artificial Intelligence Cyber Challenge and to the Advanced Research Projects Agency for Health. In October 2024, The Intercept revealed that OpenAI's tools are considered "essential" for AFRICOM's mission and included in an "Exception to Fair Opportunity" contractual agreement between the United States Department of Defense and Microsoft. In December 2024, OpenAI said it would partner with defense-tech company Anduril to build drone defense technologies for the United States and its allies. In 2025, OpenAI's Chief Product Officer, Kevin Weil, was commissioned lieutenant colonel in the U.S. Army to join Detachment 201 as senior advisor. In June 2025, the U.S. Department of Defense awarded OpenAI a $200 million one-year contract to develop AI tools for military and national security applications. OpenAI announced a new program, OpenAI for Government, to give federal, state, and local governments access to its models, including ChatGPT. Services In February 2019, GPT-2 was announced, which gained attention for its ability to generate human-like text. In 2020, OpenAI announced GPT-3, a language model trained on large internet datasets. GPT-3 is aimed at natural language answering questions, but it can also translate between languages and coherently generate improvised text. It also announced that an associated API, named the API, would form the heart of its first commercial product. Eleven employees left OpenAI, mostly between December 2020 and January 2021, in order to establish Anthropic. In 2021, OpenAI introduced DALL-E, a specialized deep learning model adept at generating complex digital images from textual descriptions, utilizing a variant of the GPT-3 architecture. In December 2022, OpenAI received widespread media coverage after launching a free preview of ChatGPT, its new AI chatbot based on GPT-3.5. According to OpenAI, the preview received over a million signups within the first five days. According to anonymous sources cited by Reuters in December 2022, OpenAI Global, LLC was projecting $200 million of revenue in 2023 and $1 billion in revenue in 2024. After ChatGPT was launched, Google announced a similar chatbot, Bard, amid internal concerns that ChatGPT could threaten Google’s position as a primary source of online information. On February 7, 2023, Microsoft announced that it was building AI technology based on the same foundation as ChatGPT into Microsoft Bing, Edge, Microsoft 365 and other products. On March 14, 2023, OpenAI released GPT-4, both as an API (with a waitlist) and as a feature of ChatGPT Plus. On November 6, 2023, OpenAI launched GPTs, allowing individuals to create customized versions of ChatGPT for specific purposes, further expanding the possibilities of AI applications across various industries. On November 14, 2023, OpenAI announced they temporarily suspended new sign-ups for ChatGPT Plus due to high demand. Access for newer subscribers re-opened a month later on December 13. In December 2024, the company launched the Sora model. It also launched OpenAI o1, an early reasoning model that was internally codenamed strawberry. Additionally, ChatGPT Pro—a $200/month subscription service offering unlimited o1 access and enhanced voice features—was introduced, and preliminary benchmark results for the upcoming OpenAI o3 models were shared. On January 23, 2025, OpenAI released Operator, an AI agent and web automation tool for accessing websites to execute goals defined by users. The feature was only available to Pro users in the United States. OpenAI released deep research agent, nine days later. It scored a 27% accuracy on the benchmark Humanity's Last Exam (HLE). Altman later stated GPT-4.5 would be the last model without full chain-of-thought reasoning. In July 2025, reports indicated that AI models by both OpenAI and Google DeepMind solved mathematics problems at the level of top-performing students in the International Mathematical Olympiad. OpenAI's large language model was able to achieve gold medal-level performance, reflecting significant progress in AI's reasoning abilities. On October 6, 2025, OpenAI unveiled its Agent Builder platform during the company's DevDay event. The platform includes a visual drag-and-drop interface that lets developers and businesses design, test, and deploy agentic workflows with limited coding. On October 21, 2025, OpenAI introduced ChatGPT Atlas, a browser integrating the ChatGPT assistant directly into web navigation, to compete with existing browsers such as Google Chrome and Apple Safari. On December 11, 2025, OpenAI announced GPT-5.2. This model will be better at creating spreadsheets, building presentations, perceiving images, writing code and understanding long context. On January 27, 2026, OpenAI introduced Prism, a LaTeX-native workspace meant to assist scientists to help with research and writing. The platform utilizes GPT-5.2 as a backend to automate the process of drafting for scientific papers, including features for managing citations, complex equation formatting, and real-time collaborative editing. In March 2023, the company was criticized for disclosing particularly few technical details about products like GPT-4, contradicting its initial commitment to openness and making it harder for independent researchers to replicate its work and develop safeguards. OpenAI cited competitiveness and safety concerns to justify this repudiation. OpenAI's former chief scientist Ilya Sutskever argued in 2023 that open-sourcing increasingly capable models was increasingly risky, and that the safety reasons for not open-sourcing the most potent AI models would become "obvious" in a few years. In September 2025, OpenAI published a study on how people use ChatGPT for everyday tasks. The study found that "non-work tasks" (according to an LLM-based classifier) account for more than 72 percent of all ChatGPT usage, with a minority of overall usage related to business productivity. In July 2023, OpenAI launched the superalignment project, aiming within four years to determine how to align future superintelligent systems. OpenAI promised to dedicate 20% of its computing resources to the project, although the team denied receiving anything close to 20%. OpenAI ended the project in May 2024 after its co-leaders Ilya Sutskever and Jan Leike left the company. In August 2025, OpenAI was criticized after thousands of private ChatGPT conversations were inadvertently exposed to public search engines like Google due to an experimental "share with search engines" feature. The opt-in toggle, intended to allow users to make specific chats discoverable, resulted in some discussions including personal details such as names, locations, and intimate topics appearing in search results when users accidentally enabled it while sharing links. OpenAI announced the feature's permanent removal on August 1, 2025, and the company began coordinating with search providers to remove the exposed content, emphasizing that it was not a security breach but a design flaw that heightened privacy risks. CEO Sam Altman acknowledged the issue in a podcast, noting users often treat ChatGPT as a confidant for deeply personal matters, which amplified concerns about AI handling sensitive data. Management In 2018, Musk resigned from his Board of Directors seat, citing "a potential future conflict [of interest]" with his role as CEO of Tesla due to Tesla's AI development for self-driving cars. OpenAI stated that Musk's financial contributions were below $45 million. On March 3, 2023, Reid Hoffman resigned from his board seat, citing a desire to avoid conflicts of interest with his investments in AI companies via Greylock Partners, and his co-founding of the AI startup Inflection AI. Hoffman remained on the board of Microsoft, a major investor in OpenAI. In May 2024, Chief Scientist Ilya Sutskever resigned and was succeeded by Jakub Pachocki. Co-leader Jan Leike also departed amid concerns over safety and trust. OpenAI then signed deals with Reddit, News Corp, Axios, and Vox Media. Paul Nakasone then joined the board of OpenAI. In August 2024, cofounder John Schulman left OpenAI to join Anthropic, and OpenAI's president Greg Brockman took extended leave until November. In September 2024, CTO Mira Murati left the company. In November 2025, Lawrence Summers resigned from the board of directors. Governance and legal issues In May 2023, Sam Altman, Greg Brockman and Ilya Sutskever posted recommendations for the governance of superintelligence. They stated that superintelligence could happen within the next 10 years, allowing a "dramatically more prosperous future" and that "given the possibility of existential risk, we can't just be reactive". They proposed creating an international watchdog organization similar to IAEA to oversee AI systems above a certain capability threshold, suggesting that relatively weak AI systems on the other side should not be overly regulated. They also called for more technical safety research for superintelligences, and asked for more coordination, for example through governments launching a joint project which "many current efforts become part of". In July 2023, the FTC issued a civil investigative demand to OpenAI to investigate whether the company's data security and privacy practices to develop ChatGPT were unfair or harmed consumers (including by reputational harm) in violation of Section 5 of the Federal Trade Commission Act of 1914. These are typically preliminary investigative matters and are nonpublic, but the FTC's document was leaked. In July 2023, the FTC launched an investigation into OpenAI over allegations that the company scraped public data and published false and defamatory information. They asked OpenAI for comprehensive information about its technology and privacy safeguards, as well as any steps taken to prevent the recurrence of situations in which its chatbot generated false and derogatory content about people. The agency also raised concerns about ‘circular’ spending arrangements—for example, Microsoft extending Azure credits to OpenAI while both companies shared engineering talent—and warned that such structures could negatively affect the public. In September 2024, OpenAI's global affairs chief endorsed the UK's "smart" AI regulation during testimony to a House of Lords committee. In February 2025, OpenAI CEO Sam Altman stated that the company is interested in collaborating with the People's Republic of China, despite regulatory restrictions imposed by the U.S. government. This shift comes in response to the growing influence of the Chinese artificial intelligence company DeepSeek, which has disrupted the AI market with open models, including DeepSeek V3 and DeepSeek R1. Following DeepSeek's market emergence, OpenAI enhanced security protocols to protect proprietary development techniques from industrial espionage. Some industry observers noted similarities between DeepSeek's model distillation approach and OpenAI's methodology, though no formal intellectual property claim was filed. According to Oliver Roberts, in March 2025, the United States had 781 state AI bills or laws. OpenAI advocated for preempting state AI laws with federal laws. According to Scott Kohler, OpenAI has opposed California's AI legislation and suggested that the state bill encroaches on a more competent federal government. Public Citizen opposed a federal preemption on AI and pointed to OpenAI's growth and valuation as evidence that existing state laws have not hampered innovation. Before May 2024, OpenAI required departing employees to sign a lifelong non-disparagement agreement forbidding them from criticizing OpenAI and acknowledging the existence of the agreement. Daniel Kokotajlo, a former employee, publicly stated that he forfeited his vested equity in OpenAI in order to leave without signing the agreement. Sam Altman stated that he was unaware of the equity cancellation provision, and that OpenAI never enforced it to cancel any employee's vested equity. However, leaked documents and emails refute this claim. On May 23, 2024, OpenAI sent a memo releasing former employees from the agreement. OpenAI was sued for copyright infringement by authors Sarah Silverman, Matthew Butterick, Paul Tremblay and Mona Awad in July 2023. In September 2023, 17 authors, including George R. R. Martin, John Grisham, Jodi Picoult and Jonathan Franzen, joined the Authors Guild in filing a class action lawsuit against OpenAI, alleging that the company's technology was illegally using their copyrighted work. The New York Times also sued the company in late December 2023. In May 2024 it was revealed that OpenAI had destroyed its Books1 and Books2 training datasets, which were used in the training of GPT-3, and which the Authors Guild believed to have contained over 100,000 copyrighted books. In 2021, OpenAI developed a speech recognition tool called Whisper. OpenAI used it to transcribe more than one million hours of YouTube videos into text for training GPT-4. The automated transcription of YouTube videos raised concerns within OpenAI employees regarding potential violations of YouTube's terms of service, which prohibit the use of videos for applications independent of the platform, as well as any type of automated access to its videos. Despite these concerns, the project proceeded with notable involvement from OpenAI's president, Greg Brockman. The resulting dataset proved instrumental in training GPT-4. In February 2024, The Intercept as well as Raw Story and Alternate Media Inc. filed lawsuit against OpenAI on copyright litigation ground. The lawsuit is said to have charted a new legal strategy for digital-only publishers to sue OpenAI. On April 30, 2024, eight newspapers filed a lawsuit in the Southern District of New York against OpenAI and Microsoft, claiming illegal harvesting of their copyrighted articles. The suing publications included The Mercury News, The Denver Post, The Orange County Register, St. Paul Pioneer Press, Chicago Tribune, Orlando Sentinel, Sun Sentinel, and New York Daily News. In June 2023, a lawsuit claimed that OpenAI scraped 300 billion words online without consent and without registering as a data broker. It was filed in San Francisco, California, by sixteen anonymous plaintiffs. They also claimed that OpenAI and its partner as well as customer Microsoft continued to unlawfully collect and use personal data from millions of consumers worldwide to train artificial intelligence models. On May 22, 2024, OpenAI entered into an agreement with News Corp to integrate news content from The Wall Street Journal, the New York Post, The Times, and The Sunday Times into its AI platform. Meanwhile, other publications like The New York Times chose to sue OpenAI and Microsoft for copyright infringement over the use of their content to train AI models. In November 2024, a coalition of Canadian news outlets, including the Toronto Star, Metroland Media, Postmedia, The Globe and Mail, The Canadian Press and CBC, sued OpenAI for using their news articles to train its software without permission. In October 2024 during a New York Times interview, Suchir Balaji accused OpenAI of violating copyright law in developing its commercial LLMs which he had helped engineer. He was a likely witness in a major copyright trial against the AI company, and was one of several of its current or former employees named in court filings as potentially having documents relevant to the case. On November 26, 2024, Balaji died by suicide. His death prompted the circulation of conspiracy theories alleging that he had been deliberately silenced. California Congressman Ro Khanna endorsed calls for an investigation. On April 24, 2025, Ziff Davis sued OpenAI in Delaware federal court for copyright infringement. Ziff Davis is known for publications such as ZDNet, PCMag, CNET, IGN and Lifehacker. In April 2023, the EU's European Data Protection Board (EDPB) formed a dedicated task force on ChatGPT "to foster cooperation and to exchange information on possible enforcement actions conducted by data protection authorities" based on the "enforcement action undertaken by the Italian data protection authority against OpenAI about the ChatGPT service". In late April 2024 NOYB filed a complaint with the Austrian Datenschutzbehörde against OpenAI for violating the European General Data Protection Regulation. A text created with ChatGPT gave a false date of birth for a living person without giving the individual the option to see the personal data used in the process. A request to correct the mistake was denied. Additionally, neither the recipients of ChatGPT's work nor the sources used, could be made available, OpenAI claimed. OpenAI was criticized for lifting its ban on using ChatGPT for "military and warfare". Up until January 10, 2024, its "usage policies" included a ban on "activity that has high risk of physical harm, including", specifically, "weapons development" and "military and warfare". Its new policies prohibit "[using] our service to harm yourself or others" and to "develop or use weapons". In August 2025, the parents of a 16-year-old boy who died by suicide filed a wrongful death lawsuit against OpenAI (and CEO Sam Altman), alleging that months of conversations with ChatGPT about mental health and methods of self-harm contributed to their son's death and that safeguards were inadequate for minors. OpenAI expressed condolences and said it was strengthening protections (including updated crisis response behavior and parental controls). Coverage described it as a first-of-its-kind wrongful death case targeting the company's chatbot. The complaint was filed in California state court in San Francisco. In November 2025, the Social Media Victims Law Center and Tech Justice Law Project filed seven lawsuits against OpenAI, of which four lawsuits alleged wrongful death. The suits were filed on behalf of Zane Shamblin, 23, of Texas; Amaurie Lacey, 17, of Georgia; Joshua Enneking, 26, of Florida; and Joe Ceccanti, 48, of Oregon, who each committed suicide after prolonged ChatGPT usage. In December 2025, Stein-Erik Soelberg, who was 56 years old at the time, allegedly murdered his mother Suzanne Adams. In the months prior the paranoid, delusional man often discussed his ideas with ChatGPT. Adam's estate then sued OpenAI claiming that the company shared responsibility due to the risk of chatbot psychosis despite the fact that chatbot psychosis is not a real medical diagnosis. OpenAI responded saying they will make ChatGPT safer for users disconnected from reality. See also References Further reading External links |

Contents PyMC PyMC (formerly known as PyMC3) is a probabilistic programming library for Python. It can be used for Bayesian statistical modeling and probabilistic machine learning. PyMC performs inference based on advanced Markov chain Monte Carlo and/or variational fitting algorithms. It is a rewrite from scratch of the previous version of the PyMC software. Unlike PyMC2, which had used Fortran extensions for performing computations, PyMC relies on PyTensor, a Python library that allows defining, optimizing, and efficiently evaluating mathematical expressions involving multi-dimensional arrays. From version 3.8 PyMC relies on ArviZ to handle plotting, diagnostics, and statistical checks. PyMC and Stan are the two most popular probabilistic programming tools. PyMC is an open source project, developed by the community and has been fiscally sponsored by NumFOCUS. PyMC has been used to solve inference problems in several scientific domains, including astronomy, epidemiology, molecular biology, crystallography, chemistry, ecology and psychology. Previous versions of PyMC were also used widely, for example in climate science, public health, neuroscience, and parasitology. After Theano announced plans to discontinue development in 2017, the PyMC team evaluated TensorFlow Probability as a computational backend, but decided in 2020 to fork Theano under the name Aesara. Large parts of the Theano codebase have been refactored and compilation through JAX and Numba were added. The PyMC team has released the revised computational backend under the name PyTensor and continues the development of PyMC. Inference engines PyMC implements non-gradient-based and gradient-based Markov chain Monte Carlo (MCMC) algorithms for Bayesian inference and stochastic, gradient-based variational Bayesian methods for approximate Bayesian inference.

Contents Joke A joke is a display of humour in which words are used within a specific and well-defined narrative structure to make people laugh and is usually not meant to be interpreted literally. It usually takes the form of a story, often with dialogue, and ends in a punch line, whereby the humorous element of the story is revealed; this can be done using a pun or other type of word play, irony or sarcasm, logical incompatibility, hyperbole, or other means. Linguist Robert Hetzron offers the definition: A joke is a short humorous piece of oral literature in which the funniness culminates in the final sentence, called the punchline… In fact, the main condition is that the tension should reach its highest level at the very end. No continuation relieving the tension should be added. As for its being "oral," it is true that jokes may appear printed, but when further transferred, there is no obligation to reproduce the text verbatim, as in the case of poetry. It is generally held that jokes benefit from brevity, containing no more detail than is needed to set the scene for the punchline at the end. In the case of riddle jokes or one-liners, the setting is implicitly understood, leaving only the dialogue and punchline to be verbalised. However, subverting these and other common guidelines can also be a source of humour—the shaggy dog story is an example of an anti-joke; although presented as a joke, it contains a long drawn-out narrative of time, place and character, rambles through many pointless inclusions and finally fails to deliver a punchline. Jokes are a form of humour, but not all humour is in the form of a joke. Some humorous forms which are not verbal jokes are: involuntary humour, situational humour, practical jokes, slapstick and anecdotes. Identified as one of the simple forms of oral literature by the Dutch linguist André Jolles, jokes are passed along anonymously. They are told in both private and public settings; a single person tells a joke to his friend in the natural flow of conversation, or a set of jokes is told to a group as part of scripted entertainment. Jokes are also passed along in written form or, more recently, through the internet. Stand-up comics, comedians and slapstick work with comic timing and rhythm in their performance, and may rely on actions as well as on the verbal punchline to evoke laughter. This distinction has been formulated in the popular saying "A comic says funny things; a comedian says things funny".[note 1] History in print Jokes do not belong to refined culture, but rather to the entertainment and leisure of all classes. As such, any printed versions were considered ephemera, i.e., temporary documents created for a specific purpose and intended to be thrown away. Many of these early jokes deal with scatological and sexual topics, entertaining to all social classes but not to be valued and saved.[citation needed] Various kinds of jokes have been identified in ancient pre-classical texts.[note 2] The oldest identified joke is an ancient Sumerian proverb from 1900 BC containing toilet humour: "Something which has never occurred since time immemorial; a young woman did not fart in her husband's lap." Its records were dated to the Old Babylonian period and the joke may go as far back as 2300 BC. The second oldest joke found, discovered on the Westcar Papyrus and believed to be about Sneferu, was from Ancient Egypt c. 1600 BC: "How do you entertain a bored pharaoh? You sail a boatload of young women dressed only in fishing nets down the Nile and urge the pharaoh to go catch a fish." The tale of the three ox drivers from Adab completes the three known oldest jokes in the world. This is a comic triple dating back to 1200 BC Adab. It concerns three men seeking justice from a king on the matter of ownership over a newborn calf, for whose birth they all consider themselves to be partially responsible. The king seeks advice from a priestess on how to rule the case, and she suggests a series of events involving the men's households and wives. The final portion of the story (which included the punch line), has not survived intact, though legible fragments suggest it was bawdy in nature. Jokes can be notoriously difficult to translate from language to language; particularly puns, which depend on specific words and not just on their meanings. For instance, Julius Caesar once sold land at a surprisingly cheap price to his lover Servilia, who was rumoured to be prostituting her daughter Tertia to Caesar in order to keep his favour. Cicero remarked that "conparavit Servilia hunc fundum tertia deducta." The punny phrase, "tertia deducta", can be translated as "with one-third off (in price)", or "with Tertia putting out." The earliest extant joke book is the Philogelos (Greek for The Laughter-Lover), a collection of 265 jokes written in crude ancient Greek dating to the fourth or fifth century AD. The author of the collection is obscure and a number of different authors are attributed to it, including "Hierokles and Philagros the grammatikos", just "Hierokles", or, in the Suda, "Philistion". British classicist Mary Beard states that the Philogelos may have been intended as a jokester's handbook of quips to say on the fly, rather than a book meant to be read straight through. Many of the jokes in this collection are surprisingly familiar, even though the typical protagonists are less recognisable to contemporary readers: the absent-minded professor, the eunuch, and people with hernias or bad breath. The Philogelos even contains a joke similar to Monty Python's "Dead Parrot Sketch". During the 15th century, the printing revolution spread across Europe following the development of the movable type printing press. This was coupled with the growth of literacy in all social classes. Printers turned out Jestbooks along with Bibles to meet both lowbrow and highbrow interests of the populace. One early anthology of jokes was the Facetiae by the Italian Poggio Bracciolini, first published in 1470. The popularity of this jest book can be measured on the twenty editions of the book documented alone for the 15th century. Another popular form was a collection of jests, jokes and funny situations attributed to a single character in a more connected, narrative form of the picaresque novel. Examples of this are the characters of Rabelais in France, Till Eulenspiegel in Germany, Lazarillo de Tormes in Spain and Master Skelton in England. There is also a jest book ascribed to William Shakespeare, the contents of which appear to both inform and borrow from his plays. All of these early jestbooks corroborate both the rise in the literacy of the European populations and the general quest for leisure activities during the Renaissance in Europe. The practice of printers using jokes and cartoons as page fillers was also widely used in the broadsides and chapbooks of the 19th century and earlier. With the increase in literacy in the general population and the growth of the printing industry, these publications were the most common forms of printed material between the 16th and 19th centuries throughout Europe and North America. Along with reports of events, executions, ballads and verse, they also contained jokes. Only one of many broadsides archived in the Harvard library is described as "1706. Grinning made easy; or, Funny Dick's unrivalled collection of curious, comical, odd, droll, humorous, witty, whimsical, laughable, and eccentric jests, jokes, bulls, epigrams, &c. With many other descriptions of wit and humour." These cheap publications, ephemera intended for mass distribution, were read alone, read aloud, posted and discarded. There are many types of joke books in print today; a search on the internet provides a plethora of titles available for purchase. They can be read alone for solitary entertainment, or used to stock up on new jokes to entertain friends. Some people try to find a deeper meaning in jokes, as in "Plato and a Platypus Walk into a Bar... Understanding Philosophy Through Jokes".[note 3] However a deeper meaning is not necessary to appreciate their inherent entertainment value. Magazines frequently use jokes and cartoons as filler for the printed page. Reader's Digest closes out many articles with an (unrelated) joke at the bottom of the article. The New Yorker was first published in 1925 with the stated goal of being a "sophisticated humour magazine" and is still known for its cartoons. Telling jokes Telling a joke is a cooperative effort; it requires that the teller and the audience mutually agree in one form or another to understand the narrative which follows as a joke. In a study of conversation analysis, the sociologist Harvey Sacks describes in detail the sequential organisation in the telling of a single joke. "This telling is composed, as for stories, of three serially ordered and adjacently placed types of sequences … the preface [framing], the telling, and the response sequences." Folklorists expand this to include the context of the joking. Who is telling what jokes to whom? And why is he telling them when? The context of the joke-telling in turn leads into a study of joking relationships, a term coined by anthropologists to refer to social groups within a culture who engage in institutionalised banter and joking. Framing is done with a (frequently formulaic) expression which keys the audience in to expect a joke. "Have you heard the one…", "Reminds me of a joke I heard…", "So, a lawyer and a doctor…"; these conversational markers are just a few examples of linguistic frames used to start a joke. Regardless of the frame used, it creates a social space and clear boundaries around the narrative which follows. Audience response to this initial frame can be acknowledgement and anticipation of the joke to follow. It can also be a dismissal, as in "this is no joking matter" or "this is no time for jokes". The performance frame serves to label joke-telling as a culturally marked form of communication. Both the performer and audience understand it to be set apart from the "real" world. "An elephant walks into a bar…"; a person sufficiently familiar with both the English language and the way jokes are told automatically understands that such a compressed and formulaic story, being told with no substantiating details, and placing an unlikely combination of characters into an unlikely setting and involving them in an unrealistic plot, is the start of a joke, and the story that follows is not meant to be taken at face value (i.e. it is non-bona-fide communication). The framing itself invokes a play mode; if the audience is unable or unwilling to move into play, then nothing will seem funny. Following its linguistic framing the joke, in the form of a story, can be told. It is not required to be verbatim text like other forms of oral literature such as riddles and proverbs. The teller can and does modify the text of the joke, depending both on memory and the present audience. The important characteristic is that the narrative is succinct, containing only those details which lead directly to an understanding and decoding of the punchline. This requires that it support the same (or similar) divergent scripts which are to be embodied in the punchline. The punchline is intended to make the audience laugh. A linguistic interpretation of this punchline/response is elucidated by Victor Raskin in his Script-based Semantic Theory of Humour. Humour is evoked when a trigger contained in the punchline causes the audience to abruptly shift its understanding of the story from the primary (or more obvious) interpretation to a secondary, opposing interpretation. "The punchline is the pivot on which the joke text turns as it signals the shift between the [semantic] scripts necessary to interpret [re-interpret] the joke text." To produce the humour in the verbal joke, the two interpretations (i.e. scripts) need to both be compatible with the joke text and opposite or incompatible with each other. Thomas R. Shultz, a psychologist, independently expands Raskin's linguistic theory to include "two stages of incongruity: perception and resolution." He explains that "… incongruity alone is insufficient to account for the structure of humour. […] Within this framework, humour appreciation is conceptualized as a biphasic sequence involving first the discovery of incongruity followed by a resolution of the incongruity." In the case of a joke, that resolution generates laughter. This is the point at which the field of neurolinguistics offers some insight into the cognitive processing involved in this abrupt laughter at the punchline. Studies by the cognitive science researchers Coulson and Kutas directly address the theory of script switching articulated by Raskin in their work. The article "Getting it: Human event-related brain response to jokes in good and poor comprehenders" measures brain activity in response to reading jokes. Additional studies by others in the field support more generally the theory of two-stage processing of humour, as evidenced in the longer processing time they require. In the related field of neuroscience, it has been shown that the expression of laughter is caused by two partially independent neuronal pathways: an "involuntary" or "emotionally driven" system and a "voluntary" system. This study adds credence to the common experience when exposed to an off-colour joke; a laugh is followed in the next breath by a disclaimer: "Oh, that's bad…" Here the multiple steps in cognition are clearly evident in the stepped response, the perception being processed just a breath faster than the resolution of the moral/ethical content in the joke. Expected response to a joke is laughter. The joke teller hopes the audience "gets it" and is entertained. This leads to the premise that a joke is actually an "understanding test" between individuals and groups. If the listeners do not get the joke, they are not understanding the two scripts which are contained in the narrative as they were intended. Or they do "get it" and do not laugh; it might be too obscene, too gross or too dumb for the current audience. A woman might respond differently to a joke told by a male colleague around the water cooler than she would to the same joke overheard in a women's lavatory. A joke involving toilet humour may be funnier told on the playground at elementary school than on a college campus. The same joke will elicit different responses in different settings. The punchline in the joke remains the same, however, it is more or less appropriate depending on the current context. The context explores the specific social situation in which joking occurs. The narrator automatically modifies the text of the joke to be acceptable to different audiences, while at the same time supporting the same divergent scripts in the punchline. The vocabulary used in telling the same joke at a university fraternity party and to one's grandmother might well vary. In each situation, it is important to identify both the narrator and the audience as well as their relationship with each other. This varies to reflect the complexities of a matrix of different social factors: age, sex, race, ethnicity, kinship, political views, religion, power relationships, etc. When all the potential combinations of such factors between the narrator and the audience are considered, then a single joke can take on infinite shades of meaning for each unique social setting. The context, however, should not be confused with the function of the joking. "Function is essentially an abstraction made on the basis of a number of contexts". In one long-term observation of men coming off the late shift at a local café, joking with the waitresses was used to ascertain sexual availability for the evening. Different types of jokes, going from general to topical into explicitly sexual humour signalled openness on the part of the waitress for a connection. This study describes how jokes and joking are used to communicate much more than just good humour. That is a single example of the function of joking in a social setting, but there are others. Sometimes jokes are used simply to get to know someone better. What makes them laugh, what do they find funny? Jokes concerning politics, religion or sexual topics can be used effectively to gauge the attitude of the audience to any one of these topics. They can also be used as a marker of group identity, signalling either inclusion or exclusion for the group. Among pre-adolescents, "dirty" jokes allow them to share information about their changing bodies. And sometimes joking is just simple entertainment for a group of friends. Relationships The context of joking in turn leads to a study of joking relationships, a term coined by anthropologists to refer to social groups within a culture who take part in institutionalised banter and joking. These relationships can be either one-way or a mutual back and forth between partners. The joking relationship is defined as a peculiar combination of friendliness and antagonism. The behaviour is such that in any other social context it would express and arouse hostility; but it is not meant seriously and must not be taken seriously. There is a pretence of hostility along with a real friendliness. To put it in another way, the relationship is one of permitted disrespect. Joking relationships were first described by anthropologists within kinship groups in Africa. But they have since been identified in cultures around the world, where jokes and joking are used to mark and reinforce appropriate boundaries of a relationship. Electronic The advent of electronic communications at the end of the 20th century introduced new traditions into jokes. A verbal joke or cartoon is emailed to a friend or posted on a bulletin board; reactions include a replied email with a :-) or LOL, or a forward on to further recipients. Interaction is limited to the computer screen and for the most part solitary. While preserving the text of a joke, both context and variants are lost in internet joking; for the most part, emailed jokes are passed along verbatim. The framing of the joke frequently occurs in the subject line: "RE: laugh for the day" or something similar. The forward of an email joke can increase the number of recipients exponentially. Internet joking forces a re-evaluation of social spaces and social groups. They are no longer only defined by physical presence and locality, they also exist in the connectivity in cyberspace. "The computer networks appear to make possible communities that, although physically dispersed, display attributes of the direct, unconstrained, unofficial exchanges folklorists typically concern themselves with". This is particularly evident in the spread of topical jokes, "that genre of lore in which whole crops of jokes spring up seemingly overnight around some sensational event … flourish briefly and then disappear, as the mass media move on to fresh maimings and new collective tragedies". This correlates with the new understanding of the internet as an "active folkloric space" with evolving social and cultural forces and clearly identifiable performers and audiences. A study by the folklorist Bill Ellis documented how an evolving cycle was circulated over the internet. By accessing message boards that specialised in humour immediately following the 9/11 disaster, Ellis was able to observe in real-time both the topical jokes being posted electronically and responses to the jokes. Previous folklore research has been limited to collecting and documenting successful jokes, and only after they had emerged and come to folklorists' attention. Now, an Internet-enhanced collection creates a time machine, as it were, where we can observe what happens in the period before the risible moment, when attempts at humour are unsuccessful Access to archived message boards also enables us to track the development of a single joke thread in the context of a more complicated virtual conversation. Joke cycles A joke cycle is a collection of jokes about a single target or situation which displays consistent narrative structure and type of humour. Some well-known cycles are elephant jokes using nonsense humour, dead baby jokes incorporating black humour, and light bulb jokes, which describe all kinds of operational stupidity. Joke cycles can centre on ethnic groups, professions (viola jokes), catastrophes, settings (…walks into a bar), absurd characters (wind-up dolls), or logical mechanisms which generate the humour (knock-knock jokes). A joke can be reused in different joke cycles; an example of this is the same Head & Shoulders joke refitted to the tragedies of Vic Morrow, Admiral Mountbatten and the crew of the Challenger space shuttle.[note 4] These cycles seem to appear spontaneously, spread rapidly across countries and borders only to dissipate after some time. Folklorists and others have studied individual joke cycles in an attempt to understand their function and significance within the culture. Joke cycles circulated in the recent past include: As with the 9/11 disaster discussed above, cycles attach themselves to celebrities or national catastrophes such as the death of Diana, Princess of Wales, the death of Michael Jackson, and the Space Shuttle Challenger disaster. These cycles arise regularly as a response to terrible unexpected events which command the national news. An in-depth analysis of the Challenger joke cycle documents a change in the type of humour circulated following the disaster, from February to March 1986. "It shows that the jokes appeared in distinct 'waves', the first responding to the disaster with clever wordplay and the second playing with grim and troubling images associated with the event…The primary social function of disaster jokes appears to be to provide closure to an event that provoked communal grieving, by signalling that it was time to move on and pay attention to more immediate concerns". The sociologist Christie Davies has written extensively on ethnic jokes told in countries around the world. In ethnic jokes he finds that the "stupid" ethnic target in the joke is no stranger to the culture, but rather a peripheral social group (geographic, economic, cultural, linguistic) well known to the joke tellers. So Americans tell jokes about Polacks and Italians, Germans tell jokes about Ostfriesens, and the English tell jokes about the Irish. In a review of Davies' theories it is said that "For Davies, [ethnic] jokes are more about how joke tellers imagine themselves than about how they imagine those others who serve as their putative targets…The jokes thus serve to center one in the world – to remind people of their place and to reassure them that they are in it." A third category of joke cycles identifies absurd characters as the butt: for example the grape, the dead baby or the elephant. Beginning in the 1960s, social and cultural interpretations of these joke cycles, spearheaded by the folklorist Alan Dundes, began to appear in academic journals. Dead baby jokes are posited to reflect societal changes and guilt caused by widespread use of contraception and abortion beginning in the 1960s.[note 5] Elephant jokes have been interpreted variously as stand-ins for American blacks during the Civil Rights Era or as an "image of something large and wild abroad in the land captur[ing] the sense of counterculture" of the sixties. These interpretations strive for a cultural understanding of the themes of these jokes which go beyond the simple collection and documentation undertaken previously by folklorists and ethnologists. Classification systems As folktales and other types of oral literature became collectables throughout Europe in the 19th century (Brothers Grimm et al.), folklorists and anthropologists of the time needed a system to organise these items. The Aarne–Thompson classification system was first published in 1910 by Antti Aarne, and later expanded by Stith Thompson to become the most renowned classification system for European folktales and other types of oral literature. Its final section addresses anecdotes and jokes, listing traditional humorous tales ordered by their protagonist; "This section of the Index is essentially a classification of the older European jests, or merry tales – humorous stories characterized by short, fairly simple plots. …" Due to its focus on older tale types and obsolete actors (e.g., numbskull), the Aarne–Thompson Index does not provide much help in identifying and classifying the modern joke. A more granular classification system used widely by folklorists and cultural anthropologists is the Thompson Motif Index, which separates tales into their individual story elements. This system enables jokes to be classified according to individual motifs included in the narrative: actors, items and incidents. It does not provide a system to classify the text by more than one element at a time while at the same time making it theoretically possible to classify the same text under multiple motifs. The Thompson Motif Index has spawned further specialised motif indices, each of which focuses on a single aspect of one subset of jokes. A sampling of just a few of these specialised indices have been listed under other motif indices. Here one can select an index for medieval Spanish folk narratives, another index for linguistic verbal jokes, and a third one for sexual humour. To assist the researcher with this increasingly confusing situation, there are also multiple bibliographies of indices as well as a how-to guide on creating your own index. Several difficulties have been identified with these systems of identifying oral narratives according to either tale types or story elements. A first major problem is their hierarchical organisation; one element of the narrative is selected as the major element, while all other parts are arrayed subordinate to this. A second problem with these systems is that the listed motifs are not qualitatively equal; actors, items and incidents are all considered side-by-side. And because incidents will always have at least one actor and usually have an item, most narratives can be ordered under multiple headings. This leads to confusion about both where to order an item and where to find it. A third significant problem is that the "excessive prudery" common in the middle of the 20th century means that obscene, sexual and scatological elements were regularly ignored in many of the indices. The folklorist Robert Georges has summed up the concerns with these existing classification systems: …Yet what the multiplicity and variety of sets and subsets reveal is that folklore [jokes] not only takes many forms, but that it is also multifaceted, with purpose, use, structure, content, style, and function all being relevant and important. Any one or combination of these multiple and varied aspects of a folklore example [such as jokes] might emerge as dominant in a specific situation or for a particular inquiry. It has proven difficult to organise all different elements of a joke into a multi-dimensional classification system which could be of real value in the study and evaluation of this (primarily oral) complex narrative form. The General Theory of Verbal Humour or GTVH, developed by the linguists Victor Raskin and Salvatore Attardo, attempts to do exactly this. This classification system was developed specifically for jokes and later expanded to include longer types of humorous narratives. Six different aspects of the narrative, labelled Knowledge Resources or KRs, can be evaluated largely independently of each other, and then combined into a concatenated classification label. These six KRs of the joke structure include: As development of the GTVH progressed, a hierarchy of the KRs was established to partially restrict the options for lower-level KRs depending on the KRs defined above them. For example, a lightbulb joke (SI) will always be in the form of a riddle (NS). Outside of these restrictions, the KRs can create a multitude of combinations, enabling a researcher to select jokes for analysis which contain only one or two defined KRs. It also allows for an evaluation of the similarity or dissimilarity of jokes depending on the similarity of their labels. "The GTVH presents itself as a mechanism … of generating [or describing] an infinite number of jokes by combining the various values that each parameter can take. … Descriptively, to analyze a joke in the GTVH consists of listing the values of the 6 KRs (with the caveat that TA and LM may be empty)." This classification system provides a functional multi-dimensional label for any joke, and indeed any verbal humour. Joke and humour research Many academic disciplines lay claim to the study of jokes (and other forms of humour) as within their purview. Fortunately, there are enough jokes, good, bad and worse, to go around. The studies of jokes from each of the interested disciplines bring to mind the tale of the blind men and an elephant where the observations, although accurate reflections of their own competent methodological inquiry, frequently fail to grasp the beast in its entirety. This attests to the joke as a traditional narrative form which is indeed complex, concise and complete in and of itself. It requires a "multidisciplinary, interdisciplinary, and cross-disciplinary field of inquiry" to truly appreciate these nuggets of cultural insight.[note 6] Sigmund Freud was one of the first modern scholars to recognise jokes as an important object of investigation. In his 1905 study Jokes and their Relation to the Unconscious Freud describes the social nature of humour and illustrates his text with many examples of contemporary Viennese jokes. His work is particularly noteworthy in this context because Freud distinguishes in his writings between jokes, humour and the comic. These are distinctions which become easily blurred in many subsequent studies where everything funny tends to be gathered under the umbrella term of "humour", making for a much more diffuse discussion. Since the publication of Freud's study, psychologists have continued to explore humour and jokes in their quest to explain, predict and control an individual's "sense of humour". Why do people laugh? Why do people find something funny? Can jokes predict character, or vice versa, can character predict the jokes an individual laughs at? What is a "sense of humour"? A current review of the popular magazine Psychology Today lists over 200 articles discussing various aspects of humour; in psychological jargon, the subject area has become both an emotion to measure and a tool to use in diagnostics and treatment. A new psychological assessment tool, the Values in Action Inventory developed by the American psychologists Christopher Peterson and Martin Seligman includes humour (and playfulness) as one of the core character strengths of an individual. As such, it could be a good predictor of life satisfaction. For psychologists, it would be useful to measure both how much of this strength an individual has and how it can be measurably increased. A 2007 survey of existing tools to measure humour identified more than 60 psychological measurement instruments. These measurement tools use many different approaches to quantify humour along with its related states and traits. There are tools to measure an individual's physical response by their smile; the Facial Action Coding System (FACS) is one of several tools used to identify any one of multiple types of smiles. Or the laugh can be measured to calculate the funniness response of an individual; multiple types of laughter have been identified. It must be stressed here that both smiles and laughter are not always a response to something funny. In trying to develop a measurement tool, most systems use "jokes and cartoons" as their test materials. However, because no two tools use the same jokes, and across languages this would not be feasible, how does one determine that the assessment objects are comparable? Moving on, whom does one ask to rate the sense of humour of an individual? Does one ask the person themselves, an impartial observer, or their family, friends and colleagues? Furthermore, has the current mood of the test subjects been considered; someone with a recent death in the family might not be much prone to laughter. Given the plethora of variants revealed by even a superficial glance at the problem, it becomes evident that these paths of scientific inquiry are mined with problematic pitfalls and questionable solutions. The psychologist Willibald Ruch [de] has been very active in the research of humour. He has collaborated with the linguists Raskin and Attardo on their General Theory of Verbal Humour (GTVH) classification system. Their goal is to empirically test both the six autonomous classification types (KRs) and the hierarchical ordering of these KRs. Advancement in this direction would be a win-win for both fields of study; linguistics would have empirical verification of this multi-dimensional classification system for jokes, and psychology would have a standardised joke classification with which they could develop verifiably comparable measurement tools. "The linguistics of humor has made gigantic strides forward in the last decade and a half and replaced the psychology of humor as the most advanced theoretical approach to the study of this important and universal human faculty." This recent statement by one noted linguist and humour researcher describes, from his perspective, contemporary linguistic humour research. Linguists study words, how words are strung together to build sentences, how sentences create meaning which can be communicated from one individual to another, and how our interaction with each other using words creates discourse. Jokes have been defined above as oral narratives in which words and sentences are engineered to build toward a punchline. The linguist's question is: what exactly makes the punchline funny? This question focuses on how the words used in the punchline create humour, in contrast to the psychologist's concern (see above) with the audience's response to the punchline. The assessment of humour by psychologists "is made from the individual's perspective; e.g. the phenomenon associated with responding to or creating humor and not a description of humor itself." Linguistics, on the other hand, endeavours to provide a precise description of what makes a text funny. Two major new linguistic theories have been developed and tested within the last decades. The first was advanced by Victor Raskin in "Semantic Mechanisms of Humor", published 1985. While being a variant on the more general concepts of the incongruity theory of humour, it is the first theory to identify its approach as exclusively linguistic. The Script-based Semantic Theory of Humour (SSTH) begins by identifying two linguistic conditions which make a text funny. It then goes on to identify the mechanisms involved in creating the punchline. This theory established the semantic/pragmatic foundation of humour as well as the humour competence of speakers.[note 7] Several years later the SSTH was incorporated into a more expansive theory of jokes put forth by Raskin and his colleague Salvatore Attardo. In the General Theory of Verbal Humour, the SSTH was relabelled as a Logical Mechanism (LM) (referring to the mechanism which connects the different linguistic scripts in the joke) and added to five other independent Knowledge Resources (KR). Together these six KRs could now function as a multi-dimensional descriptive label for any piece of humorous text. Linguistics has developed further methodological tools which can be applied to jokes: discourse analysis and conversation analysis of joking. Both of these subspecialties within the field focus on "naturally occurring" language use, i.e. the analysis of real (usually recorded) conversations. One of these studies has already been discussed above, where Harvey Sacks describes in detail the sequential organisation in telling a single joke. Discourse analysis emphasises the entire context of social joking, the social interaction which cradles the words. Folklore and cultural anthropology have perhaps the strongest claims on jokes as belonging to their bailiwick. Jokes remain one of the few remaining forms of traditional folk literature transmitted orally in western cultures. Identified as one of the "simple forms" of oral literature by André Jolles in 1930, they have been collected and studied since there were folklorists and anthropologists abroad in the lands. As a genre they were important enough at the beginning of the 20th century to be included under their own heading in the Aarne–Thompson index first published in 1910: Anecdotes and jokes. Beginning in the 1960s, cultural researchers began to expand their role from collectors and archivists of "folk ideas" to a more active role of interpreters of cultural artefacts. One of the foremost scholars active during this transitional time was the folklorist Alan Dundes. He started asking questions of tradition and transmission with the key observation that "No piece of folklore continues to be transmitted unless it means something, even if neither the speaker nor the audience can articulate what that meaning might be." In the context of jokes, this then becomes the basis for further research. Why is the joke told right now? Only in this expanded perspective is an understanding of its meaning to the participants possible. This questioning resulted in a blossoming of monographs to explore the significance of many joke cycles. What is so funny about absurd nonsense elephant jokes? Why make light of dead babies? In an article on contemporary German jokes about Auschwitz and the Holocaust, Dundes justifies this research: Whether one finds Auschwitz jokes funny or not is not an issue. This material exists and should be recorded. Jokes are always an important barometer of the attitudes of a group. The jokes exist and they obviously must fill some psychic need for those individuals who tell them and those who listen to them. A stimulating generation of new humour theories flourishes like mushrooms in the undergrowth: Elliott Oring's theoretical discussions on "appropriate ambiguity" and Amy Carrell's hypothesis of an "audience-based theory of verbal humor (1993)" to name just a few. In his book Humor and Laughter: An Anthropological Approach, the anthropologist Mahadev Apte presents a solid case for his own academic perspective. "Two axioms underlie my discussion, namely, that humor is by and large culture based and that humor can be a major conceptual and methodological tool for gaining insights into cultural systems." Apte goes on to call for legitimising the field of humour research as "humorology"; this would be a field of study incorporating an interdisciplinary character of humour studies. While the label "humorology" has yet to become a household word, great strides are being made in the international recognition of this interdisciplinary field of research. The International Society for Humor Studies was founded in 1989 with the stated purpose to "promote, stimulate and encourage the interdisciplinary study of humour; to support and cooperate with local, national, and international organizations having similar purposes; to organize and arrange meetings; and to issue and encourage publications concerning the purpose of the society". It also publishes Humor: International Journal of Humor Research and holds yearly conferences to promote and inform its speciality. In 1872, Charles Darwin published one of the first "comprehensive and in many ways remarkably accurate description of laughter in terms of respiration, vocalization, facial action and gesture and posture" (Laughter) in The Expression of the Emotions in Man and Animals. In this early study Darwin raises further questions about who laughs and why they laugh; the myriad responses since then illustrate the complexities of this behaviour. To understand laughter in humans and other primates, the science of gelotology (from the Greek gelos, meaning laughter) has been established; it is the study of laughter and its effects on the body from both a psychological and physiological perspective. While jokes can provoke laughter, laughter cannot be used as a one-to-one marker of jokes because there are multiple stimuli to laughter, humour being just one of them. The other six causes of laughter listed are social context, ignorance, anxiety, derision, acting apology, and tickling. As such, the study of laughter is a secondary albeit entertaining perspective in an understanding of jokes. Computational humour is a new field of study which uses computers to model humour; it bridges the disciplines of computational linguistics and artificial intelligence. A primary ambition of this field is to develop computer programs which can both generate a joke and recognise a text snippet as a joke. Early programming attempts have dealt almost exclusively with punning because this lends itself to simple straightforward rules. These primitive programs display no intelligence; instead, they work off a template with a finite set of pre-defined punning options upon which to build. More sophisticated computer joke programs have yet to be developed. Based on our understanding of the SSTH / GTVH humour theories, it is easy to see why. The linguistic scripts (a.k.a. frames) referenced in these theories include, for any given word, a "large chunk of semantic information surrounding the word and evoked by it [...] a cognitive structure internalized by the native speaker". These scripts extend much further than the lexical definition of a word; they contain the speaker's complete knowledge of the concept as it exists in his world. As insentient machines, computers lack the encyclopaedic scripts which humans gain through life experience. They also lack the ability to gather the experiences needed to build wide-ranging semantic scripts and understand language in a broader context, a context that any child picks up in daily interaction with his environment. Further development in this field must wait until computational linguists have succeeded in programming a computer with an ontological semantic natural language processing system. It is only "the most complex linguistic structures [which] can serve any formal and/or computational treatment of humor well". Toy systems (i.e. dummy punning programs) are completely inadequate to the task. Despite the fact that the field of computational humour is small and underdeveloped, it is encouraging to note the many interdisciplinary efforts which are currently underway.

Contents DARPA The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet's launch of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements. The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996. The Economist has called DARPA "the agency that shaped the modern world", with technologies such as "Moderna's COVID-19 vaccine ... weather satellites, GPS, drones, stealth technology, voice interfaces, the personal computer, and the internet on the list of innovations for which DARPA can claim at least partial credit". Its track record of success has inspired governments around the world to launch similar research and development agencies. DARPA is independent of other military research and development and reports directly to senior Department of Defense management. DARPA comprises about 220 government employees in six technical offices, including nearly 100 program managers, who together oversee about 250 research and development programs. Stephen Winchell is the current director. History The Advanced Research Projects Agency (ARPA) was suggested by the President's Scientific Advisory Committee to President Dwight D. Eisenhower in a meeting called after the launch of Sputnik. ARPA was formally authorized by President Eisenhower in 1958 for the purpose of forming and executing research and development projects to expand the frontiers of technology and science and be able to reach far beyond immediate military requirements. The two relevant acts are the Supplemental Military Construction Authorization (Air Force) (Public Law 85-325) and Department of Defense Directive 5105.15, in February 1958. It was placed within the Office of the Secretary of Defense (OSD) and counted roughly 150 people. Its creation was directly attributed to the launching of Sputnik and to U.S. realization that the Soviet Union had developed the capacity to rapidly exploit military technology. Initial funding of ARPA was $520 million. ARPA's first director, Roy Johnson, left a $160,000 management job at General Electric for an $18,000 job at ARPA. Herbert York from Lawrence Livermore National Laboratory was hired as his scientific assistant. Johnson and York were both keen on space projects, but when NASA was established later in 1958, all space projects and most of ARPA's funding were transferred to it. Johnson resigned and ARPA was repurposed to do "high-risk", "high-gain", "far out" basic research, a posture that was enthusiastically embraced by the nation's scientists and research universities. ARPA's second director was Brigadier General Austin W. Betts, who resigned in early 1961 and was succeeded by Jack Ruina who served until 1963. Ruina, the first scientist to administer ARPA, managed to raise its budget to $250 million. It was Ruina who hired J. C. R. Licklider as the first administrator of the Information Processing Techniques Office, which played a vital role in creation of ARPANET, the basis for the future Internet. Additionally, the political and defense communities recognized the need for a high-level Department of Defense organization to formulate and execute R&D projects that would expand the frontiers of technology beyond the immediate and specific requirements of the Military Services and their laboratories. In pursuit of this mission, DARPA has developed and transferred technology programs encompassing a wide range of scientific disciplines that address the full spectrum of national security needs. From 1958 to 1965, ARPA's emphasis centered on major national issues, including space, ballistic missile defense, and nuclear test detection. During 1960, all of its civilian space programs were transferred to the National Aeronautics and Space Administration (NASA) and the military space programs to the individual services. This allowed ARPA to concentrate its efforts on the Project Defender (defense against ballistic missiles), Project Vela (nuclear test detection), and Project AGILE (counterinsurgency R&D) programs, and to begin work on computer processing, behavioral sciences, and materials sciences. The DEFENDER and AGILE programs formed the foundation of DARPA sensor, surveillance, and directed energy R&D, particularly in the study of radar, infrared sensing, and x-ray/gamma ray detection. ARPA at this point (1959) played an early role in Transit (also called NavSat) a predecessor to the Global Positioning System (GPS). "Fast-forward to 1959 when a joint effort between DARPA and the Johns Hopkins Applied Physics Laboratory began to fine-tune the early explorers' discoveries. TRANSIT, sponsored by the Navy and developed under the leadership of Richard Kirschner at Johns Hopkins, was the first satellite positioning system." During the late 1960s, with the transfer of these mature programs to the Services, ARPA redefined its role and concentrated on a diverse set of relatively small, essentially exploratory research programs. The agency was renamed the Defense Advanced Research Projects Agency (DARPA) in 1972, and during the early 1970s, it emphasized direct energy programs, information processing, and tactical technologies.[citation needed] Concerning information processing, DARPA made great progress, initially through its support of the development of time-sharing. All modern operating systems rely on concepts invented for the Multics system, developed by a cooperation among Bell Labs, General Electric and MIT, which DARPA supported by funding Project MAC at MIT with an initial two-million-dollar grant. DARPA supported the evolution of the ARPANET (the first wide-area packet switching network), Packet Radio Network, Packet Satellite Network and ultimately, the Internet and research in the artificial intelligence fields of speech recognition and signal processing, including parts of Shakey the robot. DARPA also supported the early development of both hypertext and hypermedia. DARPA funded one of the first two hypertext systems, Douglas Engelbart's NLS computer system, as well as The Mother of All Demos. DARPA later funded the development of the Aspen Movie Map, which is generally seen as the first hypermedia system and an important precursor of virtual reality. The Mansfield Amendment of 1973 expressly limited appropriations for defense research (through ARPA/DARPA) only to projects with direct military application. The resulting "brain drain" is credited with boosting the development of the fledgling personal computer industry. Some young computer scientists left the universities to startups and private research laboratories such as Xerox PARC. Between 1976 and 1981, DARPA's major projects were dominated by air, land, sea, and space technology, tactical armor and anti-armor programs, infrared sensing for space-based surveillance, high-energy laser technology for space-based missile defense, antisubmarine warfare, advanced cruise missiles, advanced aircraft, and defense applications of advanced computing. Many of the successful programs were transitioned to the Services, such as the foundation technologies in automatic target recognition, space-based sensing, propulsion, and materials that were transferred to the Strategic Defense Initiative Organization (SDIO), later known as the Ballistic Missile Defense Organization (BMDO), now titled the Missile Defense Agency (MDA). During the 1980s, the attention of the Agency was centered on information processing and aircraft-related programs, including the National Aerospace Plane (NASP) or Hypersonic Research Program. The Strategic Computing Program enabled DARPA to exploit advanced processing and networking technologies and to rebuild and strengthen relationships with universities after the Vietnam War. In addition, DARPA began to pursue new concepts for small, lightweight satellites (LIGHTSAT) and directed new programs regarding defense manufacturing, submarine technology, and armor/anti-armor. In 1981, two engineers, Robert McGhee and Kenneth Waldron, started to develop the Adaptive Suspension Vehicle (ASV) nicknamed the "Walker" at the Ohio State University, under a research contract from DARPA. The vehicle was 17 feet long, 8 feet wide, and 10.5 feet high, and had six legs to support its three-ton aluminum body, in which it was designed to carry cargo over difficult terrains. However, DARPA lost interest in the ASV, after problems with cold-weather tests. In 2001, DARPA established the Information Awareness Office (IAO) with the stated mission of applying surveillance technology to target terrorists and other threats through "Total Information Awareness". This consisted of creating enormous computer databases to gather and store the personal information of everyone in the United States, including personal e-mails, social networks, credit card records, phone calls, medical records, and numerous other sources, without any requirement for a search warrant. In 2003, following public criticism that this would lead to a mass surveillance system, the IAO was defunded by Congress, but several IAO projects persisted under different names until revealed by Edward Snowden in the 2013 mass surveillance disclosures. On February 4, 2004, the agency shut down its so called "LifeLog Project". The project's aim would have been, "to gather in a single place just about everything an individual says, sees or does". On October 28, 2009, the agency broke ground on a new facility in Arlington County, Virginia a few miles from The Pentagon. In fall 2011, DARPA hosted the 100-Year Starship Symposium with the aim of getting the public to start thinking seriously about interstellar travel. On June 5, 2016, NASA and DARPA announced that it planned to build new X-planes with NASA's plan setting to create a whole series of X planes over the next 10 years. Between 2014 and 2016, DARPA shepherded the first machine-to-machine computer security competition, the Cyber Grand Challenge (CGC), bringing a group of top-notch computer security experts to search for security vulnerabilities, exploit them, and create fixes that patch those vulnerabilities in a fully automated fashion. It is one of DARPA prize competitions to spur innovations. In June 2018, DARPA leaders demonstrated a number of new technologies that were developed within the framework of the GXV-T program. The goal of this program is to create a lightly armored combat vehicle of not very large dimensions, which, due to maneuverability and other tricks, can successfully resist modern anti-tank weapon systems. In September 2020, DARPA and the US Air Force announced that the Hypersonic Air-breathing Weapon Concept (HAWC) are ready for free-flight tests within the next year. Victoria Coleman became the director of DARPA in November 2020. In recent years, DARPA officials have contracted out core functions to corporations. For example, during fiscal year 2020, Chenega ran physical security on DARPA's premises, System High Corp. carried out program security, and Agile Defense ran unclassified IT services. General Dynamics runs classified IT services. Strategic Analysis Inc. provided support services regarding engineering, science, mathematics, and front office and administrative work. Organization DARPA has six technical offices that manage the agency's research portfolio, and two additional offices that manage special projects. All offices report to the DARPA director, including: A 1991 reorganization created several offices which existed throughout the early 1990s: A 2010 reorganization merged two offices: Directors of DARPA have included: Projects A list of DARPA's active and archived projects is available on the agency's website. Because of the agency's fast pace, programs constantly start and stop based on the needs of the U.S. government. Structured information about some of the DARPA's contracts and projects is publicly available. Notable fiction DARPA is well known as a high-tech government agency, and as such has many appearances in popular fiction. Some realistic references to DARPA in fiction are as "ARPA" in Tom Swift and the Visitor from Planet X (DARPA consults on a technical threat), in episodes of television program The West Wing (the ARPA-DARPA distinction), the television program Numb3rs, and the Netflix film Spectral.
