Even before Wikipedia, several attempts to operate an online encyclopedia were unsuccessful. The English version of Wikipedia comes from Nupedia (now nonexistent), an encyclopedia written by experts. Nupedia was launched on March 9, 2000 by Bomi, a web portal company. Bomi's CEO Jimmy Wales and editor Larry Sanger decided to present Nupedia's articles as open content, under the GNU Free Documentation License led by Richard Stallman. Nupedia wasn't very successful, and Jimmy Wales and Larry Sanger set up Wikipedia as an encyclopedia that anyone could participate in. Sanger puts Wiki in the name to make its goal of being an encyclopedia for everyone. On January 10, 2001, Sanger announced via the Nupedia mailing list that the wiki had been introduced to complement the Nupedia project.
Launch and Growth
Wikipedia was launched on January 15, 2001. The domain was www.wikipedia.com, and the language used was only English. Larry Sanger also announced the launch of Wikipedia through the Nupedia mailing list. Within a month of Wikipedia's launch, the neutrality policy was established. After several policies were established, Wikipedia became a separate service from Nupedia. Initially, Bomis intended to run Wikipedia as a for-profit operation. Wikipedia's early editors came in through Nupedia, Slashdot, and the web search engine. On August 8, 2001, Wikipedia had about 8,000 articles. By the end of 2001, Wikipedia had expanded to 18 language editions, and the number of documents had increased to over 20,000. The number of languages in which Wikipedia was serviced increased to 26 at the end of 2002, 46 at the end of 2003, and 161 at the end of 2004. Nupedia was operated in parallel with Wikipedia, then transferred the content to Wikipedia and shut down the server in 2003.
In 2002, concerns arose among users of Wikipedia's advertising orders and its commercial operation, which prompted Spanish Wikipedia users to fork the Wikipedia source and create a separate Wikipedia, Enciclopedia Libre Universal en Español. was opened. Stimulated by this, Jimmy Wales announced that he would not introduce advertisements to Wikipedia, and changed the domain from wikipedia.com to wikipedia.org. passed the wiki
