context_page_description: Wikipedia is a multilingual online encyclopedia created and maintained as an open collaboration project by a community of volunteer editors using a wiki-based editing system. It is the largest and most popular general reference work on the World Wide Web. It is also one of the 15 most popular websites ranked by Alexa, as of August 2020. It features exclusively free content and no commercial ads. It is hosted by the Wikimedia Foundation, a non-profit organization funded primarily through donations.
  Wikipedia was launched on January 15, 2001, and was created by Jimmy Wales and Larry Sanger. Sanger coined its name as a portmanteau of the terms "wiki" and "encyclopedia". Initially an English-language encyclopedia, versions of Wikipedia in other languages were quickly developed. With 6.1 million articles, the English Wikipedia is the largest of the more than 300 Wikipedia encyclopedias. Overall, Wikipedia comprises more than 54 million articles attracting 1.5 billion unique visitors per month.
context_section_description: Other collaborative online encyclopedias were attempted before Wikipedia, but none were as successful. Wikipedia began as a complementary project for Nupedia, a free online English-language encyclopedia project whose articles were written by experts and reviewed under a formal process. It was founded on March 9, 2000, under the ownership of Bomis, a web portal company. Its main figures were Bomis CEO Jimmy Wales and Larry Sanger, editor-in-chief for Nupedia and later Wikipedia. Nupedia was initially licensed under its own Nupedia Open Content License, but even before Wikipedia was founded, Nupedia switched to the GNU Free Documentation License at the urging of Richard Stallman. Wales is credited with defining the goal of making a publicly editable encyclopedia, while Sanger is credited with the strategy of using a wiki to reach that goal. On January 10, 2001, Sanger proposed on the Nupedia mailing list to create a wiki as a "feeder" project for Nupedia.
