Wikipedia wik-ih-PEE-dee-? or /?w?ki-/ wik-ee-) is a multilingual open-collaborative online encyclopedia created and maintained by a community of volunteer editors using a wiki-based editing system. It is one of the 15 most popular websites as ranked by Alexa, as of August 2020. Featuring no ads, it is hosted by the Wikimedia Foundation, an American non-profit organization funded primarily through donations., Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger. Sanger coined its name as a portmanteau of "wiki" and "encyclopedia". It was initially an English-language encyclopedia, but versions in other languages were quickly developed. With 6.2 million articles, the English Wikipedia is the largest of the more than 300 Wikipedia encyclopedias. Overall, Wikipedia comprises more than 55 million articles attracting 1.5 billion unique visitors per month., Wikipedia has been criticized for its uneven accuracy and exhibiting systemic and gender bias, where the majority of editors are male. Edit-a-thons have been held to encourage female editors and increase the coverage of women's topics. In 2006 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. The project's reputation improved further in the 2010s as it increased efforts to improve its quality and reliability. In 2018 Facebook and YouTube announced that they would help users detect fake news by suggesting links to related Wikipedia articles.
