Wikipedia (/ˌwɪkɪˈpdiə/ (About this soundlisten)/ˌwɪkiˈpdiə/ (About this soundlisten) WIK-ih-PEE-dee-ə) is a multilingual online encyclopedia with exclusively free content and no ads (though donations are accepted), based on open collaboration through a model of content editing using web-based applications such as web browsers, called wiki. It is the largest and most popular general reference work on the World Wide Web,[3][4][5] and is one of the most popular websites by Alexa rank as of April 2019.[6] It is owned and supported by the Wikimedia Foundation, a non-profit organization that operates on money it receives from donors to remain ad-free.[7][8][9][10]

Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger.[11] Sanger coined its name,[12][13] as a portmanteau of wiki (the Hawai’ian word for “quick”[14]) and “encyclopedia“. Initially an English-language encyclopedia, versions in other languages were quickly developed. With 5,861,248 articles,[notes 3] the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias. Overall, Wikipedia comprises more than 40 million articles in 301 different languages[15] and by February 2014 it had reached 18 billion page views and nearly 500 million unique visitors per month.[16]

In 2005, Nature published a peer review comparing 42 hard science articles from Encyclopædia Britannica and Wikipedia and found that Wikipedia’s level of accuracy approached that of Britannica,[17] although critics suggested that it might not have fared so well in a similar study of a random sampling of all articles or one focused on social science or contentious social issues.[18][19] The following year, Time magazine stated that the open-door policy of allowing anyone to edit had made Wikipedia the biggest and possibly the best encyclopedia in the world, and was a testament to the vision of Jimmy Wales.[20]

Wikipedia has been criticized for exhibiting systemic bias, for presenting a mixture of “truths, half truths, and some falsehoods”,[21] and for being subject to manipulation and spin in controversial topics.[22] But by 2017, Facebook announced that it would help readers detect fake news by suggesting links to related Wikipedia articles. YouTube announced a similar plan in 2018.[23]
