Wikipedia began as a complementary project for Nupedia, a free online encyclopedia project whose articles were written by experts and reviewed by a formal process. Nupedia was founded on March 9, 2000, under the ownership of Bomis, Inc, a web portal company. Its principal figures were Jimmy Wales, Bomis CEO, and Larry Sanger, editor-in-chief for Nupedia and later Wikipedia. Nupedia was licensed initially under its own Nupedia Open Content License, switching to the GNU Free Documentation License before Wikipedia's founding at the urging of Richard Stallman.[17]

On January 10, 2001, Larry Sanger proposed on the Nupedia mailing list to create a wiki as a "feeder" project for Nupedia.[18] Wikipedia was formally launched on January 15, 2001, as a single English-language edition at http://www.wikipedia.com/, and announced by Sanger on the Nupedia mailing list.[19] Wikipedia's policy of "neutral point-of-view"[20] was codified in its initial months, and was similar to Nupedia's earlier "nonbiased" policy. Otherwise, there were relatively few rules initially and Wikipedia operated independently of Nupedia.[21] Wikipedia gained early contributors from Nupedia, Slashdot postings, and search engine indexing. It grew to approximately 20,000 articles, and 18 language editions, by the end of 2001. It grew to 26 language editions by the end of 2002, 46 by the end of 2003, and 161 by the end of 2004.[22] Nupedia and Wikipedia coexisted until the former's servers went down permanently in 2003, and its text was incorporated into Wikipedia. Larry Sanger and Jimmy Wales are both the co-founders of Wikipedia.[2][23]
Although Wales is credited with defining the goal of making a publicly editable encyclopedia,[21] Sanger is usually credited with the strategy of using a wiki to reach that goal.[24]
Citing fears of commercial advertising and lack of control in a perceived English-centric Wikipedia, users of the Spanish Wikipedia forked from Wikipedia to create the Enciclopedia Libre in February 2002. Later that year, Wales announced that Wikipedia would not display advertisements, and its website was moved to wikipedia.org. Various other projects have since forked from Wikipedia for editorial reasons. Wikinfo does not require neutral point of view and allows original research. New Wikipedia-inspired projects — such as Citizendium, Scholarpedia and Amapedia — have been started to address perceived limitations of Wikipedia, such as its policies on peer review, original research and commercial advertising.
The number of English Wikipedia articles grew steadily from 2002 to 2006, with a doubling time of roughly 1 year.

The Wikimedia Foundation was created from Wikipedia and Nupedia on June 20, 2003.[26]
The Wikimedia Foundation applied to the United States Patent and Trademark Office to trademark Wikipedia® on September 17, 2004. The mark was granted registration status on January 10, 2006. Trademark protection was accorded by Japan on December 16, 2004 and in the European Union on January 20, 2005. Technically a service mark, the scope of the mark is for: "Provision of information in the field of general encyclopedic knowledge via the Internet". There are plans to license the usage of the Wikipedia trademark for some products, such as books or DVDs.[27]
As of 2007, English Wikipedia had over 1.7 million articles, making it the largest encyclopedia ever assembled, eclipsing even the Yongle Encyclopedia (1407), which held the record for nearly 600 years.[28]
Historically, Wikipedia has been steadily gaining status since its inception. As of 2007, according to Alexa’s top 500 websites, by number of visitors, Wikipedia has become the tenth most visited website world-wide
