From Wikipedia, the free encyclopedia
Wikipedia, a free-content online encyclopedia written and maintained by a community of volunteers known as Wikipedians, began with its first edit on 15 January 2001, two days after the domain was registered.[2] It grew out of Nupedia, a more structured free encyclopedia, as a way to allow easier and faster drafting of articles and translations.

The technological and conceptual underpinnings of Wikipedia predate this; the earliest known proposal for an online encyclopedia was made by Rick Gates in 1993,[3] and the concept of a free-as-in-freedom online encyclopedia (as distinct from mere open source)[4] was proposed by Richard Stallman in 1998.[5]
Stallman's concept specifically included the idea that no central organization should control editing. This contrasted with contemporary digital encyclopedias such as Microsoft Encarta and Encyclopædia Britannica. In 2001, the license for Nupedia was changed to GFDL, and Jimmy Wales and Larry Sanger launched Wikipedia as a complementary project, using an online wiki as a collaborative drafting tool.[6]
While Wikipedia was initially imagined as a place to draft articles and ideas for eventual polishing in Nupedia, it quickly overtook its predecessor, becoming both draft space and home for the polished final product of a global project in hundreds of languages, inspiring a wide range of other online reference projects.
In 2014, Wikipedia had approximately 495 million monthly readers.[7] In 2015, according to comScore, Wikipedia received over 115 million monthly unique visitors from the United States alone.[8] In September 2018, the projects saw 15.5 billion monthly page views.[9]
The concept of compiling the world's knowledge in a single location dates back to the ancient Library of Alexandria and Library of Pergamum, but the modern concept of a general-purpose, widely distributed, printed encyclopedia originated with Denis Diderot and the 18th-century French encyclopedists.[10] The idea of using automated machinery beyond the printing press to build a more useful encyclopedia can be traced to Paul Otlet's 1934 book Traité de Documentation. Otlet also founded the Mundaneum, an institution dedicated to indexing the world's knowledge, in 1910. This concept of a machine-assisted encyclopedia was further expanded in H. G. Wells' book of essays World Brain (1938) and Vannevar Bush's future vision of the microfilm-based Memex in his essay "As We May Think" (1945).[11] Another milestone was Ted Nelson's hypertext design Project Xanadu, which began in 1960.[11]
The use of volunteers was integral in making and maintaining Wikipedia. However, even without the internet, huge complex projects of similar nature had made use of volunteers. Specifically, the creation of the Oxford English Dictionary was conceived with the speech at the London Library, on Guy Fawkes Day, 5 November 1857, by Richard Chenevix Trench. It took about 70 years to complete. Dr. Trench envisioned a grand new dictionary of every word in the English language, and to be used democratically and freely. According to author Simon Winchester, "The undertaking of the scheme, he said, was beyond the ability of any one man. To peruse all of English literature – and to comb the London and New York newspapers and the most literate of the magazines and journals – must be instead 'the combined action of many.' It would be necessary to recruit a team – moreover, a huge one – probably comprising hundreds and hundreds of unpaid amateurs, all of them working as volunteers."[12]
Advances in information technology in the late 20th century led to changes in the form of encyclopedias. While previous encyclopedias, notably the Encyclopædia Britannica, were often book-based, Microsoft's Encarta, published in 1993, was available on CD-ROM and hyperlinked. The development of the World Wide Web led to many attempts to develop internet encyclopedia projects. An early proposal for an online encyclopedia was Interpedia in 1993 by Rick Gates;[3] this project died before generating any encyclopedic content. Free software proponent Richard Stallman described the usefulness of a "Free Universal Encyclopedia and Learning Resource" in 1998.[5] His published document outlined how to "ensure that progress continues towards this best and most natural outcome."
Wikipedia co-founder Jimmy Wales said that the concept of Wikipedia came when he was a graduate student at Indiana University, where he was impressed with the successes of the open-source movement and found Richard Stallman's Emacs Manifesto promoting free software and a sharing economy interesting. Wales also credits Austrian School economist Friedrich Hayek's essay, "The Use of Knowledge in Society," which he read as an undergraduate,[13] as "central" to his thinking about "how to manage the Wikipedia project."[14] The essay asserts that information is decentralized—that each individual only knows a small fraction of what is known collectively—and that as a result, decisions are best made by those with local knowledge, rather than by a central authority. At the time, Wales was studying finance and was intrigued by the incentives of the many people who contributed as volunteers toward creating free software, where many examples were having excellent results.[15] According to The Economist, Wikipedia "has its roots in the techno-optimism that characterised the internet at the end of the 20th century. It held that ordinary people could use their computers as tools for liberation, education, and enlightenment."[16]
Wikipedia was initially conceived as a feeder project for the Wales-founded Nupedia, an earlier project to produce a free online encyclopedia, volunteered by Bomis, a web-advertising firm owned by Jimmy Wales, Tim Shell and Michael E. Davis.[17][18][19] Nupedia was founded upon the use of qualified volunteer contributors and a considered multi-step peer review process.[20] Despite its mailing list of over 2000 interested editors, and the presence of Sanger as full-time editor-in-chief,[21] the production of content for Nupedia was extremely slow, with only 12 articles written during the first year.[19]
The Nupedians discussed various ways to create content more rapidly.[18] Wikis had been used elsewhere on the web to organize knowledge,[22] and the idea of a wiki-based complement to Nupedia was seeded by a conversation between Sanger and Ben Kovitz,[23][24][25] and by another between Wales and Jeremy Rosenfeld.[23] Kovitz was a computer programmer and regular on Ward Cunningham's revolutionary wiki "the WikiWikiWeb". He explained to Sanger what wikis were, over a dinner on 2 January 2001.[23][24][25][26] Wales stated in October 2001 that "Larry had the idea to use Wiki software" for people bored by Nupedia process,[27] and later stated in December 2005 that Rosenfeld had introduced him to the wiki concept.[28][29][30][31] Sanger thought a wiki would be a good platform to use, and proposed on the Nupedia mailing list that a wiki based upon UseModWiki (then v. 0.90) be set up as a "feeder" project for Nupedia. Under the subject "Let's make a wiki", he wrote:[32]
No, this is not an indecent proposal. It's an idea to add a little feature to Nupedia. Jimmy Wales thinks that many people might find the idea objectionable, but I think not... As to Nupedia's use of a wiki, this is the ULTIMATE "open" and simple format for developing content. We have occasionally bandied about ideas for simpler, more open projects to either replace or supplement Nupedia. It seems to me wikis can be implemented practically instantly, need very little maintenance, and in general, are very low-risk. They're also a potentially great source of content. So there's little downside, as far as I can determine.
Wales set one up and put it online on Wednesday 10 January 2001, under the nupedia.com domain.[33] This moved to a new wiki under the wikipedia.com domain on 15 January. On 17 January, the Free Software Foundation's (FSF) GNUPedia project went online, potentially competing with Nupedia,[34] but within a few years the FSF encouraged people "to visit and contribute to [Wikipedia]" instead.[35]
There was some hesitation among editors about binding Nupedia too closely to a wiki-style workflow.[19] After a Nupedia wiki was launched under nupedia.com on 10 January 2001,[36] Wales proposed launching the new project under its own name, and Sanger proposed Wikipedia, framing it as "a supplementary project to Nupedia which operates entirely independently."[37] A new wiki was launched at wikipedia.com on Monday 15 January 2001. The bandwidth and server (located in San Diego) used for these initial projects were donated by Bomis. Many former Bomis employees later contributed content to the encyclopedia: notably Tim Shell, co-founder and later CEO of Bomis, and programmer Jason Richey.
Wales stated in December 2008 that he made Wikipedia's first edit, a test edit with the text "Hello, World!", but this may have been to an old version of Wikipedia which soon after was scrapped and replaced by a restart.[38][39] The first recovered edit to Wikipedia.com was to the HomePage on 15 January 2001, reading "This is the new WikiPedia!"; it can be found here.[40] The existence of the project was formally announced and an appeal for volunteers to engage in content creation was made to the Nupedia mailing list on 17 January 2001.[41]
The project received many new participants after being mentioned on the Slashdot website in July 2001,[42] having already earned two minor mentions in March 2001.[43][44] It then received a prominent pointer to a story on the community-edited technology and culture website Kuro5hin on 25 July.[45] Between these influxes of traffic, there had been a steady stream of traffic from other sources, especially Google, which alone sent hundreds of new visitors to the site every day. Its first major mainstream media coverage was in The New York Times on 20 September 2001.[46]
Early in Wikipedia's development, it began to expand internationally, with the creation of new namespaces, each with a distinct set of usernames. The first subdomain created for a non-English Wikipedia was deutsche.wikipedia.com (created on Friday 16 March 2001, 01:38 UTC),[47] followed after a few hours by catalan.wikipedia.com (at 13:07 UTC).[48] The Japanese Wikipedia, started as nihongo.wikipedia.com, was created around that period,[49][50] and initially used only Romanized Japanese. For about two months Catalan was the one with the most articles in a non-English language,[51][52] although statistics of that early period are imprecise.[53]
The French Wikipedia was created on or around 11 May 2001,[54] in a wave of new language versions that also included Chinese, Dutch, Esperanto, Hebrew, Italian, Portuguese, Russian, Spanish, and Swedish.[55] These languages were soon joined by Arabic[56] and Hungarian.[57][58] In September 2001, an announcement pledged commitment to the multilingual provision of Wikipedia,[59] notifying users of an upcoming roll-out of Wikipedias for all major languages, the establishment of core standards, and a push for the translation of core pages for the new wikis. At the end of that year, when international statistics first began to be logged, Afrikaans, Norwegian, and Serbian versions were announced.[60]
In January 2002, 90% of all Wikipedia articles were in English. By January 2004, fewer than 50% were English, and this internationalization has continued to increase as the encyclopedia grows. As of 2014[update], about 85% of all Wikipedia articles were in non-English Wikipedia versions.[61] As of 2023[update], the English and Simple English Wikipedias have 7 million articles between them, but roughly 90% of articles were in non-English Wikipedias.[62]
In March 2002, following the withdrawal of funding by Bomis during the dot-com bust, Sanger left both Nupedia and Wikipedia.[63] By 2002, he and Wales differed in their views on how best to manage open encyclopedias. Both still supported the open-collaboration concept, but they disagreed on how to handle disruptive editors, specific roles for experts, and the best way to guide the project to success.
Wales went on to establish self-governance and bottom-up self-direction by editors on Wikipedia. He made it clear that he would not be involved in the community's day-to-day management, but would encourage it to learn to self-manage and find its own best approaches. As of 2007[update], Wales mostly restricted his role to occasional input on serious matters, executive activity, advocacy of knowledge, and encouragement of similar reference projects.
Sanger said he is an "inclusionist" and is open to almost anything,[64] and proposed that experts still have a place in the Web 2.0 world. In 2006 he founded Citizendium, an open encyclopedia that used real names for contributors to reduce disruptive editing, and hoped to facilitate "gentle expert guidance" to increase the accuracy of its content. Decisions about article content were to be up to the community, but the site was to include a statement about "family-friendly content".[65][66]
Old, even obsolete, encyclopedia articles are highly valuable for historical research.[67] For each Wikipedia article, past versions are accessible through the "View history" link at the top of the page. In addition, the ZIM File Archive,[68] at Internet Archive, contains past full snapshots of Wikipedia as well as article selections, in multiple languages, from different years. They can be opened with Kiwix software. Between 2007 and 2011, three CD/DVD versions (called Wikipedia Version 0.5, 0.7 and 0.8) containing a selection of articles from English Wikipedia were released. They became available as Kiwix ZIM files, both from the ZIM File Archive[68] and from the Kiwix download site.[69]
In March 2000, the Nupedia project was started. Its intention was to publish articles written by experts which would be licensed as free content. Nupedia was founded by Wales, with Sanger as editor-in-chief, and funded by the web-advertising company Bomis.[70]
In January 2001, Wikipedia began as a side-project of Nupedia, to allow collaboration on articles prior to entering the peer-review process.[71] The name was suggested by Sanger on 11 January 2001 as a portmanteau of the words wiki (Hawaiian for "quick") and encyclopedia.[72] The wikipedia.com and wikipedia.org domain names were registered on 12[73] and 13 January,[74] respectively, with wikipedia.org being brought online on the same day.[75] The project formally opened on 15 January ("Wikipedia Day"), with the first international Wikipedias – the French, German, Catalan, Swedish, and Italian editions – being created between March and May. The "neutral point of view" (NPOV) policy was officially formulated at this time, and Wikipedia's first slashdotter wave arrived on 26 July.[42] The first media report about Wikipedia appeared in August 2001 in the newspaper Wales on Sunday.[76]
The September 11 attacks spurred the appearance of breaking news stories on the homepage, as well as information boxes linking related articles.[77] At the time, approximately 100 articles related to 9/11 had been created.[78] After the September 11 attacks, a link to the Wikipedia article on the attacks appeared on Yahoo!'s home page, resulting in a spike in traffic.[79]
2002 saw the reduction of funding for Wikipedia from Bomis and the departure of Sanger. A fork of the Spanish Wikipedia took place, with the establishment of the Enciclopedia Libre. Jimmy Wales confirmed that Wikipedia would never run commercial advertising. The first portable MediaWiki software went live on 25 January. Bots were introduced. The first sister project (Wiktionary) and first formal Manual of Style were launched. Close to 200 contributors were editing Wikipedia daily.[80]
The English Wikipedia passed 100,000 articles in 2003, while the next largest edition, the German Wikipedia, passed 10,000. The Wikimedia Foundation was established. Wikipedia adopted its jigsaw world logo. Mathematical formulae using TeX were reintroduced to the website. The first Wikipedian social meeting took place in Munich, Germany, in October. The basic principles of English Wikipedia's Arbitration system and committee ("ArbCom") were developed. Wikisource was created as a separate project on 24 November 2003, to host free textual sources as its aim in multiple languages and translations.
The worldwide Wikipedia article pool continued to grow rapidly in 2004, doubling in size in 12 months, from under 500,000 articles in late 2003 to over 1 million in over 100 languages by the end of 2004. The English Wikipedia accounted for just under half of these articles. The website's server farms were moved from California to Florida. Categories and CSS style configuration sheets were introduced. The first attempt to block Wikipedia occurred, with the website being blocked in China for two weeks in June. Formal elections began for a board for the Foundation, and an Arbitration Committee on English Wikipedia. The first national chapter of the Foundation, Wikimedia Deutschland, was recognized. The first social meeting in the United States took place in Boston, in July. Wikimedia Commons was created on 7 September 2004 to host media files for Wikipedia in all languages.
Bourgeois v. Peters,[81] (11th Cir. 2004), a court case decided by the United States Court of Appeals for the Eleventh Circuit was one of the earliest court opinions to cite and quote Wikipedia.[82] It stated: "We also reject the notion that the Department of Homeland Security's threat advisory level somehow justifies these searches. Although the threat level was 'elevated' at the time of the protest, 'to date, the threat level has stood at yellow (elevated) for the majority of its time in existence. It has been raised to orange (high) six times.'"[81]
In 2005, Wikipedia became the most popular reference website on the Internet, according to Hitwise, with English Wikipedia alone exceeding 750,000 articles. Wikipedia's first multilingual and subject portals were established in 2005. A formal fundraiser held in the first quarter of the year raised almost US$100,000 for system upgrades to handle growing demand. China again blocked Wikipedia in October 2005.
The first major Wikipedia scandal, the Seigenthaler incident, occurred in 2005 when a well-known figure was found to have a vandalized biography that had gone unnoticed for months. In the wake of this and other concerns,[83] the first policy and system changes specifically designed to counter this form of abuse were established. These included a new Checkuser privilege policy update to assist in sock puppetry investigations, a new feature called semi-protection, a more strict policy on biographies of living people and the tagging of such articles for stricter review. A restriction of new article creation to registered users only was put in place in December 2005.[84] Wikimania 2005, the first Wikimania conference, was held from 4 to 8 August 2005 at the Haus der Jugend in Frankfurt, attracting about 380 attendees.
The English Wikipedia gained its one-millionth article, Jordanhill railway station, on 1 March 2006.[85][86] The first approved Wikipedia article selection was made freely available to download, and "Wikipedia" became registered as a trademark of the Wikimedia Foundation. The congressional aides biography scandals – multiple incidents in which congressional staffers and a campaign manager were caught trying to covertly alter Wikipedia biographies – came to public attention, leading to the resignation of the campaign manager. Nonetheless, Wikipedia was rated as one of the top five global brands of 2006.[87]
Jimmy Wales indicated at Wikimania 2006 that Wikipedia had achieved sufficient volume and called for an emphasis on quality, perhaps best expressed in the call for 100,000 feature-quality articles. A new privilege, "oversight", was created, allowing specific versions of archived pages with unacceptable content to be marked as non-viewable. Semi-protection against anonymous vandalism, introduced in 2005, proved more popular than expected, with over 1,000 pages being semi-protected at any given time in 2006.
Wikipedia continued to grow rapidly in 2007, possessing over 5 million registered editor accounts by 13 August.[88] The 250 language editions of Wikipedia contained a combined total of 7.5 million articles, totalling 1.74 billion words, by 13 August.[89] The English Wikipedia gained articles at a steady rate of 1,700 a day,[90] with the wikipedia.org domain name ranked the 10th-busiest in the world. Wikipedia continued to garner visibility in the press – the Essjay controversy broke out when a prominent member of Wikipedia was found to have lied about his credentials. Citizendium, a competing online encyclopedia, launched publicly. A new trend developed in Wikipedia, with the encyclopedia addressing people whose notability stemmed from being a participant in a news story by adding a redirect from their name to the larger story, rather than creating a distinct biographical article.[91]
On 9 September 2007, the English Wikipedia gained its two-millionth article, El Hormiguero.[92] There was some controversy in late 2007 when the Volapük Wikipedia jumped from 797 to over 112,000 articles, briefly becoming the 15th-largest Wikipedia edition, due to automated stub generation by an enthusiast for the Volapük constructed language.[93][94] According to the MIT Technology Review, the number of regularly active editors on the English-language Wikipedia peaked in 2007 at more than 51,000, and has since been declining.[95] In April 2007, Wikipedia Version 0.5 article selection release was published.[96]
Various WikiProjects in many areas continued to expand and refine article contents within their scope. In April 2008, the 10-millionth Wikipedia article was created, and by the end of the year the English Wikipedia exceeded 2.5 million articles.
On 25 June 2009 at 22:15 UTC, following the death of Michael Jackson, the website temporarily crashed. The Wikimedia Foundation reported nearly a million visitors to Jackson's biography within one hour, probably the most visitors in a one-hour period to any article in Wikipedia's history. By late August 2009, the number of articles in all Wikipedia editions had exceeded 14 million.[97] The three-millionth article on the English Wikipedia, Beate Eriksen, was created on 17 August 2009 at 04:05 UTC.[98] On 27 December 2009, the German Wikipedia exceeded one million articles, becoming the second edition after the English Wikipedia to do so. A TIME article listed Wikipedia among 2009's best websites.[99] Wikipedia content became licensed under a Creative Commons Attribution-ShareAlike license in 2009.[100]
On 24 March, the European Wikipedia servers went offline due to an overheating problem. Failover to servers in Florida turned out to be broken, causing DNS resolution for Wikipedia to fail across the world. The problem was resolved quickly, but due to DNS caching effects, some areas were slower to regain access to Wikipedia than others.[101][102]
On 13 May, the site released a new interface. New features included an updated logo, new navigation tools, and a link wizard.[103] However, the classic interface remained available for those who wished to use it. On 12 December, the English Wikipedia passed the 3.5-million-article mark, while the French Wikipedia's millionth article was created on 21 September. The 1-billionth Wikimedia project edit was performed on 16 April.[104] In early 2010, Wikipedia Version 0.7 article selection release was published.[96]
Wikipedia and its users held many celebrations worldwide to commemorate the site's 10th anniversary on 15 January.[106] The site began efforts to expand its growth in India, holding its first Indian conference in Mumbai in November 2011.[107][108] The English Wikipedia passed the 3.6-million-article mark on 2 April, and reached 3.8 million articles on 18 November. On 7 November 2011, the German Wikipedia exceeded 100 million page edits, becoming the second language edition to do so after the English edition, which attained 500 million page edits on 24 November 2011. The Dutch Wikipedia exceeded 1 million articles on 17 December 2011, becoming the fourth Wikipedia edition to do so.
On 3 March 2011, Wikipedia Version 0.8 article selection release was published.[109] The "Wikimania 2011 – Haifa, Israel" stamp was issued by Israel Post on 2 August 2011. This was the first-ever stamp dedicated to a Wikimedia-related project. Between 4 and 6 October 2011, the Italian Wikipedia became intentionally inaccessible in protest against the Italian Parliament's proposed DDL intercettazioni law, which, if approved, would allow any person to force websites to remove information that is perceived as untrue or offensive, without the need to provide evidence.[110] Also in October 2011, Wikimedia announced the launch of Wikipedia Zero, an initiative to enable free mobile access to Wikipedia in developing countries through partnerships with mobile operators.[111][112]
On 16 January, Wikipedia co-founder Jimmy Wales announced that the English Wikipedia would shut down for 24 hours on 18 January as part of a protest meant to call public attention to the proposed Stop Online Piracy Act and PROTECT IP Act, two anti-piracy laws under debate in the United States Congress. Calling the blackout a "community decision", Wales and other opponents of the laws believed that they would endanger free speech and online innovation.[113] A similar blackout was staged on 10 July by the Russian Wikipedia, in protest against a proposed Russian internet regulation law.[114]
In late March 2012, the Wikimedia Deutschland announced Wikidata, a universal platform for sharing data between all Wikipedia language editions.[115][116] The US$1.7-million Wikidata project was partly funded by Google, the Gordon and Betty Moore Foundation, and the Allen Institute for Artificial Intelligence.[117] Wikimedia Deutschland assumed responsibility for the first phase of Wikidata, and initially planned to make the platform available to editors by December 2012. Wikidata's first phase became fully operational in March 2013.[118][119]

In April 2012, Justin Knapp became the first single contributor to make over one million edits to Wikipedia.[120][121] Jimmy Wales congratulated Knapp for his work and presented him with the site's Special Barnstar medal and the Golden Wiki award for his achievement.[122] Wales also declared that 20 April would be "Justin Knapp Day".[123]
On 13 July 2012, the English Wikipedia gained its 4-millionth article, Izbat al-Burj.[124] In October 2012, historian and Wikipedia editor Richard J. Jensen opined that the English Wikipedia was "nearing completion", noting that the number of regularly active editors had fallen significantly since 2007, despite Wikipedia's rapid growth in article count and readership.[125] According to Alexa Internet, Wikipedia was the world's sixth-most-popular website as of November 2012.[126] Dow Jones ranked Wikipedia fifth worldwide as of December 2012.[127]
On 22 January 2013, the Italian Wikipedia became the fifth language edition of Wikipedia to exceed 1 million articles, while the Russian and Spanish Wikipedias gained their millionth articles on 11 and 16 May respectively. On 15 July the Swedish and on 24 September the Polish Wikipedias gained their millionth articles, becoming the eighth and ninth Wikipedia editions to do so. On 27 January, the main belt asteroid 274301 was officially renamed "Wikipedia" by the Committee for Small Body Nomenclature.[128]
The first phase of the Wikidata database, automatically providing interlanguage links and other data, became available for all language editions in March 2013.[119] In April 2013, the French secret service was accused of attempting to censor Wikipedia by threatening a Wikipedia volunteer with arrest unless "classified information" about a military radio station was deleted.[129]
In July, the VisualEditor editing system was launched, forming the first stage of an effort to allow articles to be edited with a word processor-like interface instead of using wiki markup.[130] An editor specifically designed for smartphones and other mobile devices was also launched.[131]
In February 2014, a project to make a print edition of the English Wikipedia, consisting of 1,000 volumes and over 1,100,000 pages, was launched by German Wikipedia contributors.[7] The project sought funding through Indiegogo, and was intended to honor the contributions of Wikipedia's editors.[132] On 22 October 2014, the first monument to Wikipedia was unveiled in the Polish town of Slubice.[133]
On 8 June, 15 June, and 16 July 2014, the Waray Wikipedia, the Vietnamese Wikipedia and the Cebuano Wikipedia each exceeded the one million article mark. They were the tenth, eleventh and twelfth Wikipedias to reach that milestone. Despite having very few active users, the Waray and Cebuano Wikipedias had a high number of automatically generated articles created by bots.
In mid-2015, Wikipedia was the world's seventh-most-popular website according to Alexa Internet,[134] down one place from the position it held in November 2012. At the start of 2015, Wikipedia remained the largest general-knowledge encyclopedia online, with a combined total of over 36 million mainspace articles across all 291 language editions.[61] On average, Wikipedia receives a total of 10 billion global pageviews from around 495 million unique visitors every month,[7][135] including 85 million visitors from the United States alone,[8] where it is the sixth-most-popular site.[134]
Print Wikipedia was an art project by Michael Mandiberg that created the ability to print 7473 volumes of Wikipedia as it existed on 7 April 2015. Each volume has 700 pages and only 110 were printed by the artist.[136] On 1 November 2015, the English Wikipedia reached 5,000,000 articles with the creation of an article on Persoonia terminalis, a type of shrub.
On 19 January 2016, the Japanese Wikipedia exceeded the one million article mark, becoming the thirteenth Wikipedia to reach that milestone. The millionth article was of Wave 224, a World War II submarine of the Imperial Japanese Navy. In mid-2016, Wikipedia was once again the world's sixth-most-popular website according to Alexa Internet,[137] up one place from the position it held in the previous year.
In mid-2017, Wikipedia was listed as the world's fifth-most-popular website according to Alexa Internet,[138] rising one place from the position it held in the previous year. Wikipedia Zero was made available in Iraq and Afghanistan. On 29 April 2017, online access to Wikipedia was blocked across all language editions in Turkey by the Turkish authorities. This block lasted until 15 January 2020, as the court of Turkey ruled that the block violated human rights. The encrypted Japanese Wikipedia has been blocked in China since 28 December 2017.[139]
On 13 April 2018, the number of Chinese Wikipedia articles exceeded 1 million, becoming the fourteenth Wikipedia to reach that milestone. The Chinese Wikipedia has been blocked in Mainland China since May 2015.[140] Later in the year, on 26 June, the Portuguese Wikipedia exceeded the one million article mark, becoming the fifteenth Wikipedia to reach that milestone. The millionth article was Perdão de Richard Nixon (the Pardon of Richard Nixon). During 2018, Wikipedia retained its listing as the world's fifth-most-popular website according to Alexa Internet.[141] One notable development was the use of Artificial Intelligence to create draft articles on overlooked topics.[142]
On 23 April 2019, Chinese authorities expanded the block of Wikipedia to versions in all languages.[143][144] The timing of the block coincided with the 30th anniversary of the 1989 Tiananmen Square protests and massacre and the 100th anniversary of the May Fourth Movement, resulting in stricter internet censorship in China.[145] In August 2019, according to Alexa.com, Wikipedia fell from fifth-placed to seventh-placed website in the world for global internet engagement.[146]
On 23 January 2020, the six millionth article, the biography of Maria Elise Turner Lauder, was added to the English Wikipedia. Despite this growth in articles, Wikipedia's global internet engagement, as measured by Alexa, continued to decline. By February 2020, Wikipedia fell to the eleventh-placed website in the world for global internet engagement.[146] Both Wikipedia's coverage of the COVID-19 pandemic crisis and the supporting edits, discussions, and even deletions were thought to be a useful resource for future historians seeking to understand the period in detail.[147] The World Health Organization collaborated with Wikipedia as a key resource for the dissemination of COVID-19-related information as to help combat the spread of misinformation.[148][149]
In January 2021, Wikipedia's 20th anniversary was noted in the media.[150][151][152][153] On 13 January 2021, the English Wikipedia reached one billion edits, where the billionth edit was made by Steven Pruitt.[154] MIT Press published an open access book of essays Wikipedia @ 20: Stories of an Unfinished Revolution, edited by Joseph Reagle and Jackie Koerner with contributions from prominent Wikipedians, Wikimedians, researchers, journalists, librarians and other experts reflecting on particular histories and themes.[155] By November 2021, Wikipedia had fallen to the thirteenth-placed website in the world for global internet engagement.[146]
On 6 December 2022, Wikipedian Richard Knipel created the article Artwork title, whose first revision was a draft generated by ChatGPT that Knipel had made minor edits to more closely conform with Wikipedia standards. Knipel stated on a talk page that he believed this was the first time anyone had used ChatGPT to compose a Wikipedia article. The posting of this article was criticized by other editors and sparked controversy within the Wikipedia community, leading to an extensive debate about whether ChatGPT and similar models should be used in writing content for Wikipedia and, if so, to what extent.[156]
In January 2023, the default Wikipedia desktop interface was changed for the first time since 2010, to Vector 2022.[157] After consultation and a contest, the first sound logo of Wikimedia (including Wikipedia) was adopted.[158]
Vector 2022, an update to Wikipedia's previous skin Vector 2010, was announced in September 2020, and initially slated for debut in 2021, before being ultimately deployed in January 2023.[168] By January 2023, Wikimedia had made the update available to 300 of its language editions; it was the default for the Arabic and Greek versions.[169][170][171]
Vector 2022 features a revised user interface which makes numerous changes to the arrangement of the interface elements. Among them, the language selection menu, previously located to the left of the screen, now is found in the top right corner of the display of the article that is currently read.[171] Additionally, the sidebar is collapsible behind a hamburger button. Vector 2022 additionally increases the margins of the article display, which has the effect of limiting the width of the article;[171] a toggle exists which can decrease the margins and expand the line width of the article to fill the screen.[172][170] The default size of the text has not been increased, although the Wikimedia Foundation told Engadget that they hope to make this an option in future.[169] The search function was also updated in Vector 2022, as the suggested results in response to user queries now include images and short descriptions from the pages in question.[171][173]
The Wikimedia Foundation said that the change was motivated by a desire to modernize the site and improve the navigation and editing experience for readers inexperienced with the internet, as the previous skin was deemed "clunky and overwhelming."[168][169][172] Tests conducted by the foundation yielded results of a 30 percent increase in user searches, and a 15 percent decrease in scrolling.[169][172] Early versions of Vector 2022 first went live in 2020 on the French-, Hebrew-, and Portuguese-language Wikipedia sites,[168] as the skin's new features were rolled out to users for testing gradually before its full release.[174] The skin went live as the default skin for readers of Wikimedia sites in 300 (out of 318) languages on 18 January 2023.[169][170][171]
Following the mass rollout of Vector 2022, it is still possible to read Wikipedia using the previous skin. However, to do so requires readers to register for a Wikipedia account, and then set their preferences to display Vector 2010 instead.[171] No changes were made to existing Wikipedia skins such as Monobook and Timeless, which also remain available to use.[170][175]
Wikipedia users were divided on the changes. A request for comment on the English Wikipedia asking the community whether or not Vector 2022 should be deployed as the default skin accumulated over 90,000 words in responses.[170] Critics of the redesign objected most prominently to the white space left empty in the new skin, while other users criticized said critics as having a kneejerk resistance to change.[170] 165 editors participating in the discussion disapproved of the new skin, while 153 were in favor, and nine remained neutral.[176][170][177] Despite the larger number of editors who expressed that they did not want Vector 2022 to be deployed in its then-current form, as consensus on Wikipedia is not decided by vote, the discussion was closed in favor of the redesign, considering the positive comments left by other users.[176][170] The Vector 2022 developers made some changes to the skin in response to the criticisms, such as adding a toggle to enable article content to fill the entire width of the screen.[170][178] Users on the Swahili Wikipedia unanimously disagreed with the enactment of the new skin.[170]
Journalists responding to Vector 2022's rollout considered the update and the new features introduced as useful additions, but generally characterized the skin as a minor update that did not fundamentally change their reading experience on Wikipedia.[173][170][172] Annie Rauwerda, creator of the Depths of Wikipedia social media accounts, wrote in Slate that Vector 2022 was not "dramatically different" from the previous skin. Rauwerda additionally noted the similarity between the Wikipedia community backlash against the design and previous resistances to similar visual changes on popular sites such as Reddit.[170] Rauwerda, and Mike Pearl of Mashable, commented that users displeased with the change could weigh in on a discussion about the skin, or use the site's built-in customization features to alter their reading experience.[176][170]
Every year, the Wikimedia Foundation runs fundraising campaigns on Wikipedia to support its operations. These generally last about a month and happen at different times of the year in different countries. In addition to the fundraising banners on Wikipedia itself, there are also email campaigns; some emails invite people to leave the Wikimedia Foundation money in their wills.[210][211] Revenue has risen every year of the Wikimedia Foundation's existence, reaching US$180.17 million as of 30 June 2023, versus expenses of US$169.1 million.[212][213] In addition, the Wikimedia Endowment, an organizationally separate fundraising effort begun in 2016, reached $100 million in 2021, five years sooner than planned.[214]

Because Wikipedia biographies are often updated with new information comes, they are often used as a reference source on the lives of notable people. This has led to attempts to manipulate and falsify Wikipedia articles for promotional or defamatory purposes (Controversies) and has also led to novel uses of the biographical material provided.
Wales, along with others, came up with and funded the idea of an open-source, collaborative encyclopedia that would accept contributions from ordinary people.[19] Sanger played an important role in this as Nupedia's Editor in Chief and main employee.[227] In Sanger's introductory message to the Nupedia mailing list, he said that Jimmy Wales "contacted me and asked me to apply as editor-in-chief of Nupedia. [...] He had had the idea for Nupedia since at least last fall. He tells me that, when thinking about people (particularly philosophers) he knew who could manage this sort of long-term project, he thought I would be perfect for the job. This is indeed my dream job".[228]
Sanger suggested using a wiki to provide a complementary project for people "intimidated and bored" by Nupedia's elaborate processes,[27] and coined the portmanteau "Wikipedia" as the project name.[229][227] This was broadly seen as a way to unblock the growing community of Nupedians who found it hard to contribute.[227] Sanger continued to work on Nupedia while contributing to Wikipedia (including drafting policies such as "Ignore all rules"[230] and "Neutral point of view"[63]) and worked with an outreach lead to build up the community of both Nupedia and Wikipedia editors.[227] Upon departure in March 2002, Sanger emphasized the main issue was purely the cessation of funding for his role, which was not viable part-time,[21] and encouraged others to continue contributing to Wikipedia while noting that Nupedia could not survive without a full-time editor in chief.[21] Later that year he stopped contributing to either project, and by 2004 had become publicly critical of Wikipedia. In December 2004 he wrote an essay arguing that Wikipedia was suffering from anti-elitism.[231] In April 2005 he published a two-part memoir of his work on Nupedia and Wikipedia, highlighting his role in their creation and continuing belief that Nupedia deserved to be saved.[231] Later that year Wales began to push back on Sanger's characterization of his role in the project.[232][233][234] By 2006, after the launch of Citizendium, Sanger was harshly critical of Wikipedia, describing it as "broken beyond repair."[235]
In 2005, Wales described himself simply as the founder of Wikipedia;[232] however, according to Brian Bergstein of the Associated Press, "Sanger has long been cited as a co-founder."[227] Sanger and Wales were referred to as co-founders in various press releases, interviews, and news reports from 2001[236] and 2002.[237] Before January 2004, Wales did not dispute Sanger's status as co-founder.[238] In 2006, Wales said, "He used to work for me [...] I don't agree with calling him a co-founder, but he likes the title".[239] Starting in 2006, when Sanger wrote and was interviewed extensively about the launch of Citizendium, he emphasized his status as co-founder, and these earlier sources that described him as such.[227][236][240][241]

In a separate but similar incident, the campaign manager for Cathy Cox, Morton Brilliant, resigned after being found to have added negative information to the Wikipedia entries of political opponents.[248] Following media publicity, the incidents tapered off around August 2006.
There are a large number of Wikipedia mirror and forks. Other sites also use the MediaWiki software and concept, popularized by Wikipedia. No list of them is maintained. Specialized foreign language forks using the Wikipedia concept include Enciclopedia Libre (Spanish), Wikiweise (German), WikiZnanie (Russian), Susning.nu (Swedish), and Baidu Baike (Chinese). Some of these (such as Enciclopedia Libre) use GFDL or compatible licenses as used by Wikipedia, leading to the exchange of material with their respective language Wikipedias. In 2006, Sanger founded Citizendium, based upon a modified version of MediaWiki.[272] The site said it aimed 'to improve on the Wikipedia model with "gentle expert oversight", among other things'.[66][273] In 2006, conservative activist and lawyer Andrew Schlafly founded Conservapedia, based on MediaWiki.
The German Wikipedia was the first to be partly published also using other media (rather than online on the internet), including releases on CD in November 2004[274] and more extended versions on CDs or DVD in April 2005 and December 2006. In December 2005, the publisher Zenodot Verlagsgesellschaft mbH, a sister company of Directmedia, published a 139-page book explaining Wikipedia, its history and policies, which was accompanied by a 7.5 GB DVD containing 300,000 articles and 100,000 images from the German Wikipedia.[275] Originally, Directmedia also announced plans to print the German Wikipedia in its entirety, in 100 volumes of 800 pages each. The publication was due to begin in October 2006, and finish in 2010. In March 2006, however, this project was called off.[276]
In September 2008, Bertelsmann published a 1000 pages volume with a selection of popular German Wikipedia articles. Bertelsmann paid voluntarily 1 Euro per sold copy to Wikimedia Deutschland.[277] A free software project has also been launched to make a static version of English Wikipedia available for use on iPods. The "Encyclopodia" project was started around March 2006 and can currently be used on 1st to 4th-generation iPods.[278]
| Release | Year | Description | Link to ZIM file download |
|---|---|---|---|
| 2006 Wikipedia CD Selection | 2006 | First CD version, containing a selection of articles from the English Wikipedia. It was published in April 2006 by SOS Children.[279] | |
| Wikipedia Version 0.5 | 2007 | A CD containing around 2000 articles selected from the online encyclopedia was published by the Wikimedia Foundation and Linterweb. The selection of articles included was based on both the quality of the online version and the importance of the topic to be included. It was created as a test case in preparation for a DVD version including far more articles.[280][281] Articles are categorized according to subject. The CD version could be purchased online, downloaded as a DVD image file or Torrent file, or accessed online at the project's website. | [282][283] |
| Wikipedia Version 0.7 | 2009–2010 | First DVD version. General release of around 31,000 articles taken from all subject areas. A manual effort was performed to remove vandalism, which delayed the release date.[284] Includes topical and geographical indexes of articles, in addition to the alphabetical index. | [285][286] |
| Wikipedia Version 0.8 | 2011 | General release of around 47,300 articles taken from all subject areas. Article selection and vandalism removal using systems developed by a group of volunteers from the Wikipedia community, greatly improved release time. It includes only an alphabetical index and no article categorization. | [287][288] |
As of June 2022, there have been no more article selection releases since Wikipedia Version 0.8.[289]
In limited ways, the Wikimedia Foundation is protected by Section 230 of the Communications Decency Act. In the defamation action Bauer et al. v. Glatzer et al., it was held that Wikimedia had no case to answer because of this section.[290] A similar law in France caused a lawsuit to be dismissed in October 2007.[291] In 2013, a German appeals court or Oberlandesgericht (the Higher Regional Court of Stuttgart) ruled that Wikipedia is a "service provider" not a "content provider", and as such is immune from liability as long as it takes down content that is accused of being illegal.[292]
