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]].<ref name="hive">{{Cite magazine |last=Poe |first=Marshall |date=September 2006 |title=The Hive |url=https://www.theatlantic.com/doc/200609/wikipedia/ |url-status=live |magazine=[[The Atlantic]] |archive-url=https://web.archive.org/web/20061223004004/http://www.theatlantic.com/doc/200609/wikipedia |archive-date=23 December 2006 |access-date=1 January 2007}}</ref>

On Wikipedia, anyone can write about any subject they know about. The idea is that over time, enough experts will offer their knowledge for free and build up the world's ultimate hand-built database of knowledge. The disadvantage is that it's still an ongoing project. So far about 8,000 articles have been written and the editors are aiming for 100,000.")</ref>

====2002====
2002 saw the reduction of funding for Wikipedia from [[Bomis]] and the departure of Sanger. A [[fork (software development)|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. [[Internet bot|Bots]] were introduced. The first sister project ([[Wiktionary]]) and first formal [[Manual of Style]] were launched. Close to 200 contributors were editing Wikipedia daily.<ref name="Singer2002">{{Cite news |last=Singer |first=Michael |date=16 January 2002 |title=Free Encyclopedia Project Celebrates Year One |work=[[Mecklermedia|Jupitermedia]] |url=http://siliconvalley.internet.com/news/article.php/3531_956641 |url-status=dead |archive-url=https://web.archive.org/web/20030316082912/http://siliconvalley.internet.com/news/article.php/3531_956641 |archive-date=16 March 2003}}</ref>

====2003====
[[File:2003-08-31 English Wikipedia main page.svg|thumb|Wikipedia's main page (August 2003)]]
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 [[:de:Wikipedia:Stammtisch München/Archiv/2003|first Wikipedian social meeting]] took place in [[Munich]], Germany, in October. The basic principles of English Wikipedia's {{self-reference link|Wikipedia:ArbCom|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.

====2004====
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 farm]]s were moved from California to Florida. {{self-reference link|Wikipedia:Categories|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]], [[Wikipedia:Meetup/Boston1|in July]]. [[Wikimedia Commons]] was created on 7 September 2004 to host media files for Wikipedia in all languages.

It has been raised to orange (high) six times.{{'-}}"<ref name="Bour v Pete" />

====2005====
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,<ref name="Brandt">[[Wikipedia:Biographies of living persons|WP:BLP]] was started on 17 December 2005, with the narrative "I started this due to the Daniel Brandt situation". [https://en.wikipedia.org/w/index.php?title=Wikipedia:Biographies_of_living_persons&oldid=31753956 Wikipedia:Biographies of living persons] {{Webarchive|url=https://web.archive.org/web/20210609020908/https://en.wikipedia.org/w/index.php?title=Wikipedia:Biographies_of_living_persons&oldid=31753956 |date=9 June 2021 }}</ref> the first policy and system changes specifically designed to counter this form of abuse were established. These included a new [[m:CheckUser policy|Checkuser]] privilege policy update to assist in [[Sockpuppet (Internet)|sock puppetry]] investigations, a new feature called {{self-reference link|Wikipedia:Requests for page protection|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.<ref>{{Cite web |last=Terdiman |first=Daniel |title=Growing pains for Wikipedia |url=https://www.cnet.com/culture/growing-pains-for-wikipedia/ |access-date=16 March 2023 |publisher=CNET |language=en |archive-date=16 March 2023 |archive-url=https://web.archive.org/web/20230316055529/https://www.cnet.com/culture/growing-pains-for-wikipedia/ |url-status=live }}</ref> 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.

====2006====
The English Wikipedia gained its one-millionth article, [[Jordanhill railway station]], on 1 March 2006.<ref>{{cite magazine|last=Simon|first=Matt|date=1 March 2012|title=March 1, 2006: English Wikipedia's Millionth Entry Pulls Into the Station|magazine=[[Wired (magazine)|Wired]]|url=https://www.wired.com/2012/03/march-1-2006-english-wikipedias-millionth-entry-pulls-into-the-station/|access-date=1 April 2024}}</ref><ref>{{cite web|last=Lemon|first=Sumner|date=2 March 2006|title=Millionth English article posted on Wikipedia|website=[[Computerworld]]|url=https://www.computerworld.com/article/2563140/millionth-english-article-posted-on-wikipedia.html|access-date=1 April 2024}}</ref> The first approved Wikipedia article selection was made freely available to download, and "Wikipedia" became registered as a trademark of the Wikimedia Foundation. The [[United States congressional staff edits to Wikipedia|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.<ref>{{Cite web |date=21 March 2007 |title=brandchannel.com &#124; branding news |url=http://www.brandchannel.com/start1.asp?fa_id=352 |access-date=16 March 2023 |archive-url=https://web.archive.org/web/20070321033410/http://www.brandchannel.com/start1.asp?fa_id=352 |archive-date=21 March 2007 }}</ref>

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 [[Wikipedia:100,000 feature-quality articles|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.

====2007====
Wikipedia continued to grow rapidly in 2007, possessing over 5 million registered editor accounts by 13 August.<ref>See the special page: [[Special:Statistics]]: 5,078,036 registered user accounts as of 13 August 2007, excluding anonymous editors who have not created accounts.</ref> The 250 language editions of Wikipedia contained a combined total of 7.5 million articles, totalling 1.74 billion words, by 13 August.<ref>Source: [[Wikipedia:Size comparisons]] as of 13 August 2007</ref> The English Wikipedia gained articles at a steady rate of 1,700 a day,<ref>From around Q3 2006 Wikipedia's growth rate has been approximately linear, source: [[Wikipedia:Statistics]] – new article count by month 2006–2007.</ref> with the wikipedia.org domain name ranked the 10th-busiest in the world. Wikipedia continued to garner visibility in [[:Category:Wikipedia publicity|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.<ref>e.g., cases such as [[Crystal Mangum]] and Daniel Brandt.</ref>

On 9 September 2007, the English Wikipedia gained its two-millionth article, ''[[El Hormiguero]]''.<ref name="WFpressrelease">{{cite web|url=https://wikimediafoundation.org/wiki/Press_releases/Wikipedia_Reaches_2_Million_Articles |title=English Wikipedia Reaches 2 Million Articles |archive-url=https://web.archive.org/web/20170708005830/https://wikimediafoundation.org/wiki/Press_releases/Wikipedia_Reaches_2_Million_Articles |archive-date=8 July 2017 |website=[[Wikimedia Foundation]] |date=9 September 2007 |access-date=3 June 2012}}</ref> 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.<ref>{{Cite journal |date=1 December 2007 |title=Ciekawe wydarzenia w Internecie |url=http://www.pcworld.pl/artykuly/56502/MySpace.kontra.Facebook.html#t_34252 |url-status=live |journal=PC World (Polish) |language=pl |archive-url=https://web.archive.org/web/20131106024950/http://www.pcworld.pl/artykuly/56502/MySpace.kontra.Facebook.html#t_34252 |archive-date=6 November 2013 |access-date=26 April 2013}}</ref><ref>{{Cite web |last=Yves Nevelsteen |date=15 September 2007 |title=Volapuko jam superas Esperanton en Vikipedio |url=http://www.liberafolio.org/2007/volapukapedio |url-status=live |archive-url=https://web.archive.org/web/20130329091247/http://www.liberafolio.org/2007/volapukapedio |archive-date=29 March 2013 |access-date=26 April 2013 |website=Libera Folio |language=eo}}</ref> 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.<ref name="MIT">{{Cite journal |last=Simonite |first=Tom |date=22 October 2013 |title=The Decline of Wikipedia |url=https://www.technologyreview.com/2013/10/22/175674/the-decline-of-wikipedia/ |journal=[[MIT Technology Review]] |access-date=6 December 2020 |archive-date=31 July 2022 |archive-url=https://web.archive.org/web/20220731083716/https://www.technologyreview.com/2013/10/22/175674/the-decline-of-wikipedia/ |url-status=live }}</ref> In April 2007, Wikipedia Version 0.5 article selection release was published.<ref name="auto1">{{Citation |title=Wikipedia:Version 1.0 Editorial Team |date=2022-06-12 |url=https://en.wikipedia.org/w/index.php?title=Wikipedia:Version_1.0_Editorial_Team&oldid=1092780181 |work=Wikipedia |language=en |access-date=2022-06-25 |archive-date=7 July 2022 |archive-url=https://web.archive.org/web/20220707222542/https://en.wikipedia.org/w/index.php?title=Wikipedia:Version_1.0_Editorial_Team&oldid=1092780181 |url-status=live }}</ref>

====2008====
Various {{self-reference link|Wikipedia:WikiProject|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.

====2009====
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.

===Second decade: 2010–2019===
====2010====
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 [[Domain Name System|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.<ref>{{Cite web |last=Bergsma |first=Mark |date=24 March 2010 |title=Global Outage (cooling failure and DNS) |url=http://techblog.wikimedia.org/2010/03/global-outage-cooling-failure-and-dns/ |url-status=dead |archive-url=https://web.archive.org/web/20100327123357/http://techblog.wikimedia.org/2010/03/global-outage-cooling-failure-and-dns/ |archive-date=27 March 2010 |access-date=30 March 2010 |publisher=Wikimedia Technical Blog}}</ref><ref>{{Cite magazine |last=Perez |first=Juan Carlos |date=25 March 2010 |title=Wikipedia Suffers Global Collapse |url=https://www.pcworld.com/article/192410/wikipedia_suffers_global_collapse.html |url-status=live |magazine=PC World |archive-url=https://web.archive.org/web/20100329132858/http://www.pcworld.com/article/192410/wikipedia_suffers_global_collapse.html |archive-date=29 March 2010 |access-date=30 March 2010}}</ref>

==== 2022 ====
{{expand section|date=May 2025}}
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.<ref>{{Cite web |last=Harrison |first=Stephen |date=12 January 2023 |title=Should ChatGPT Be Used to Write Wikipedia Articles? |url=https://slate.com/technology/2023/01/chatgpt-wikipedia-articles.html |access-date=30 January 2023 |website=Slate |language=en |archive-date=28 January 2023 |archive-url=https://web.archive.org/web/20230128200141/https://slate.com/technology/2023/01/chatgpt-wikipedia-articles.html |url-status=live }}</ref>

In January 2023, the default Wikipedia desktop interface was changed for the first time since 2010, to [[Vector 2022]].<ref>{{Cite web |date=18 January 2023 |title=Wikipedia Gets a Fresh New Look: First Desktop Update in a Decade Puts Usability at the Forefront |url=https://wikimediafoundation.org/news/2023/01/18/wikipedia-gets-a-fresh-new-look-first-desktop-update-in-a-decade-puts-usability-at-the-forefront/ |access-date=20 January 2023 |website=Wikimedia Foundation |language=en-US |archive-date=19 January 2023 |archive-url=https://web.archive.org/web/20230119234339/https://wikimediafoundation.org/news/2023/01/18/wikipedia-gets-a-fresh-new-look-first-desktop-update-in-a-decade-puts-usability-at-the-forefront/ |url-status=live }}</ref> The new interface received abundant criticism from users. Many objections focused on the fixed-width layout, which created excessive white space on the margins on wide monitors, leading to a 90,000-word discussion on whether the new skin should become the default. [[Swahili Wikipedia]] unanimously voted to reject the new skin and "curtly" demanded a return to the old skin. Other criticism was directed at the Wikimedia Foundation for hiring a design team with limited experience on wikis. Brandon Harris, who was a senior designer at Wikipedia from 2010 to 2014, said: "Wikimedia Foundation often hires designers who aren’t familiar with the community, and they come in and try to make all these changes—running head-first into a buzz saw—and the community understandably resists".<ref>{{cite web |title=Wikipedia’s Redesign Is Barely Noticeable.
