Wikipedia (/ˌwɪkɪˈpdiə/ (About this soundlisten) wik-ih-PEE-dee-ə or /ˌwɪki-/ (About this soundlisten) wik-ee-) is a free, multilingual online encyclopedia written and maintained by a community of volunteer contributors through a model of open collaboration, using a wiki-based editing system. Wikipedia is the largest and most-read reference work in history,[3] and is consistently one of the 15 most-popular websites as ranked by Alexa; as of 2021, it ranked as the 13th most-popular site.[3][4] The project carries no advertisements and is hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through individual donations.[5]

Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger; Sanger coined its name as a portmanteau of "wiki" and "encyclopedia".[6][7] Initially available only in English, versions in other languages were quickly developed, like the German Wikipedia. The English Wikipedia, with 6.3 million articles as of May 2021, is the largest of the 321 language editions. Combined, Wikipedia's editions comprise more than 56 million articles, and attract more than 17 million edits and more than 1.7 billion unique visitors per month.[8][9]

Wikipedia has received praise for its enablement of the democratization of knowledge, extent of coverage, unique structure, culture, and reduced amount of commercial bias, but has also been criticized for its perceived unreliability and for exhibiting systemic bias, namely racial bias and gender bias against women, and alleged ideological bias. In 2006, Time magazine stated that the open-door policy of allowing anyone to edit had made Wikipedia the "biggest and perhaps the best encyclopedia in the world", and a testament to the vision of Jimmy Wales.[10] In 2018, Facebook and YouTube announced that they would help users detect fake news by suggesting links to related Wikipedia articles.[11]
