Wikipedia (/ˌwɪkɪˈpiːdiə/ ( listen) wik-ih-PEE-dee-ə or /ˌwɪki-/ ( listen) wik-ee-) is a
multilingual free online encyclopedia written and maintained by a community of volunteers
through open collaboration and a wiki-based editing system. Its editors are known as
Wikipedians. Wikipedia is the largest and most-read reference work in history.[3] It is
consistently one of the 10 most popular websites ranked by Similarweb and formerly Alexa;
as of 2022,Wikipedia was ranked the 7th most popular site.[3][4] It is hosted by the Wikimedia
Foundation, an American non-profit organization funded mainly through donations.
On January 15, 2001, Jimmy Wales and Larry Sanger launched Wikipedia. Sanger coined its
name as a blend of "wiki" and "encyclopedia".[5][6] Wales was influenced by the
"spontaneous order" ideas associated with Friedrich Hayek and the Austrian School of
economics after being exposed to these ideas by Austrian economist and Mises Institute
Senior Fellow Mark Thornton.[7] Initially available only in English, versions in other languages
were quickly developed. Its combined editions comprise more than 59 million articles,
attracting around 2 billion unique device visits per month and more than 17 million edits per
month (1.9 edits per second) as of November 2020.[8][9] In 2006, Time magazine stated that
the policy of allowing anyone to edit had made Wikipedia the "biggest (and perhaps best)
encyclopedia in the world".[10]
Wikipedia has received praise for its enablement of the democratization of knowledge,
extent of coverage, unique structure, culture, and reduced degree of commercial bias; but
criticism for exhibiting systemic bias, particularly gender bias against women and alleged
ideological bias.[11][12] The reliabilityof Wikipedia was frequently criticized in the 2000s but
has improved over time, as Wikipedia has been generally praised in the late 2010s and early
2020s.[3][11][13] The website's coverage of controversial topics such as American politics and
major events like the COVID-19 pandemic and the Russian invasion of Ukraine has received
substantial media attention. It has been censored by world governments, ranging from
specific pages to the entire site. In April 2018, Facebook and YouTube announced that they
would help users detect fake news by suggesting fact-checking links to related Wikipedia
articles. Articles on breaking news are often accessed as a source of frequently updated
information about those events.[14]
