About Wikipedia, History and Headquarters Information


Wikipedia was founded in the year 2001. The company has been active for almost 18 years now. The founders of the company were Larry Sanger and Jimmy Wales. The former name of the company was Nupedia, which was launched in the year 2000. The company was licensed under the Nupedia Open Content License. Due to the urging of Richard Stallman, the company had switched to the GNU Free Documentation License as well. Then in the year 2001, Larry Sanger had proposed to create a wiki, just like a feeder project for Nupedia, and therefore Wikipedia was established.

The main domains known as Wikipedia.com and Wikipedia.org were registered in the year 2001, and Wikipedia was launched in the same year as well – mainly as a single English-language edition and had been announced by Sanger on the Nupedia mailing list as well. Wikipedia had gained early contributors from Nupedia, Slashdot postings and also web search engine indexing as well. Language editions were also created later too, with a total of more than 160 by the end of the year 2004. Nupedia and Wikipedia coexisted together until the former’s servers were taken down permanently in the year 2003 and its text was also incorporated into Wikipedia as well. The English Wikipedia had passed the mark of two million articles in the year 2007 – making it the most giant encyclopedia ever assembled as well, surpassing the 1408 Yongle Encyclopedia – which had held the record for almost 600 years in history. Though the English Wikipedia had reached three million articles in the year 2009, the growth of the edition, in terms of the numbers of new articles and also contributors, appeared to had peaked around the year 2007. Around 1,800 articles were added daily as well to the encyclopedia in the year 2006, and by the year 2013, that average was roughly almost 800 only. The Palo Alto Research Center attributed this slowing of growth to the project’s increasing exclusivity and also resistance to change as well. In the year 2009, a researcher had found that the English Wikipedia had lost almost 49,000 editors during the first three months of the year 2009 – which was in comparison, the project had lost only 4,900 editors during the same period in the year 2008 as well. In the year 2012, The Atlantic had reported that the number of administrators is also in decline as well. During the year 2013, in an issue of New York magazine, journalist Katherine Ward had stated that the company is facing an internal crisis. As of the year 2007, the company had entered for the first time the top-ten list of the most popular websites in the USA, according to comScore Networks as well. As of the year 2016, the company was ranked fifth in the most popular websites all over the world. The headquarters of the company is based in San Francisco. The name of the state is California, United States.

As of the year 2019, the company is ranked number five on the Amazon Alexa website ranking.
