Wikipedia, a project to produce a free content encyclopedia that could be edited by anyone, formally began on 15 January 2001 as a complement to the similar, but expert-written, Nupedia project.
=Antecedents=
The concept of gathering all of the world s knowledge in a single place goes back to the ancient Library of Alexandria and Pergamon, but the modern concept of a general purpose, widely distributed, printed encyclopedia dates from shortly before Denis Diderot and the 18th century encyclopedists. The idea of using automated machinery beyond the printing press to build a more useful encyclopedia can be traced to H. G. Wells short story World Brain (1937) and Vannevar Bush s future vision of the Microfilm based Memex in As We May Think (1945). Another milestone was Ted Nelson s Project Xanadu in 1960.
With the development of the Internet, many people attempted to develop Internet encyclopedia projects. Free software exponent Richard Stallman described the usefulness of a Free Universal Encyclopedia and Learning Resource in 1999. He described Wikipedia s formation as exciting news and his Free Software Foundation encourages people to visit and contribute to the site . One never-realized predecessor was the Interpedia, which Robert McHenry has linked conceptually to Wikipedia.
=Formulation of the idea=
Wikipedia was founded as an offshoot of Nupedia, a now-abandoned project to produce a free encyclopedia. Nupedia had an elaborate system of peer review and required highly qualified contributors, but the writing of articles was seen as very slow. During 2000, Jimmy Wales, founder of Nupedia, and Larry Sanger, whom Wales had employed to work on the project, discussed various ways to supplement Nupedia with a more open, complementary project.
In mid-December, 2001, Wales had a conversation with employee Jeremy Rosenfeld, the first person to ever suggest that the software which could implement Wales vision of a freely editable encyclopedia could be seen in WikiWikiWeb.
On the evening of .
=Project beginnings=
There was considerable resistance on the part of Nupedia s editors and reviewers to the idea of associating Nupedia with a website in the wiki format, however, so the new project was given the name Wikipedia and launched on its own domain, wikipedia.com, on January 15 (now humorously called Wikipedia Day by some users). The bandwidth and server (located in San Diego) were donated by Wales. Other current and past Bomis employees who have done some work on the encyclopedia include Tim Shell, one of the co-founders of Bomis and its current CEO, and programmer Jason Richey.
While the first edit on Wikipedia ever made is believed to be a test edit by .
The project received large numbers of participants after being mentioned three times on the tech website , which alone sent hundreds of new visitors to the site every day.
The project passed 1,000 articles around February 12, 2001, and 10,000 articles around September 7. In the first year of its existence, over 20,000 encyclopedia entries were created — a rate of over 1,500 articles per month. On August 30, 2002, the article count reached 40,000. The rate of growth has more or less steadily increased since the inception of the project, except for some software-induced slow-downs.
=International expansion=
The international expansion of the project also took place during this period. In versions were announced. [http://www.wikipedia.org/wiki/Wikipedia:International_wikipedias_statistics]

==2002==
Until January 2002, Sanger was employed by Bomis as editor-in-chief of Nupedia and the unofficial leader of Wikipedia. Funding ran out, however, and Sanger resigned from both positions in March 2002.
In . The project is occasionally visited by vandals who remove valid articles or post inappropriate content. While such vandalism is generally quickly reverted, the project s main page was, for a time, subjected to repeated vandalism. This led to the protection of the page so that it could only be changed by administrators.
On , was moved to the Wikipedia Namespace from the article namespace. At that time, selection was informal; the Featured Articles Candidacy process was not yet to be instituted for several years.

In October 2002, Derek Ramsey ( Ram-Man ) started to use a bot , or program, to add a large number of articles about United States towns; these articles were automatically generated from U.S. census data. Occasionally, similar bots had been used before for other topics. These articles were generally well received, but some users criticized them for their uniformity and generally machine-like writing style (for example, see [http://en.wikipedia.org/w/wiki.phtmltitle=La_Grange%2C_Illinois&oldid=2963634 this version] of a town article).
In December 2002, the sister project Wiktionary was created; it aims to produce a Dictionary and thesaurus of the words in all languages. It uses the same software as Wikipedia.
==2003==
In January 2003, support for mathematical formulas in TeX was added. The code was contributed by Tomasz Wegrzanowski.
On January 22 2003, the English Wikipedia was again slashdot effect after having reached the 100,000 article milestone. Two days later, the German language Wikipedia, the largest non-English version, passed the 10,000 article mark.
In June 20, 2003, the Wikimedia Foundation was founded. On the same day Wikiquote was created. A month later, Wikibooks was launched.
On October 28, 2003 the first real meeting of Wikipedians happened in Munich. Many cities followed suit, and soon a number of regular Wikipedian get-togethers were established around the world. Several Internet communities, including one on the popular Blog website LiveJournal, have also sprung up since.
==2004==
In January 2004, Wikipedia passed the 200,000 article milestone in English and reached 450,000 articles for both English and non-English wikis. The next month, the combined article count of the English and non-English wikis reached 500,000.

**As an illustration of the power of collaborative community efforts, on created the catmore template to support the use of the Categories. Briefly, catmore expanded into an explanation which is customized to the page into which it is inserted. Editors could then simply enter the template onto a category page to produce a customized message which relates a category to its main article. In one year, 9 users have collaborated to improve the usability of , in dozens of edits to this small macro. Now multiply this small example by the thousands of editors who understand its use, and Wikipedia is the result.

On October 20, 2005, direct access to all the Wikipedia sites have been blocked in most areas of mainland China.
=Viability=
The German Wikipedia s issue on CD-ROM and DVD-ROM helped prove a market for Wikimedia products. Within the first ten days, it presold 10,000 copies, 8,000 of which were on Amazon.de. Sales of the product, issued by Directmedia Publishing GmbH of Berlin, were certainly helped by the 9.90 price for the product.

: Main article: Blocking of Wikipedia in mainland China
The People s Republic of China and internet service providers in Mainland China have adopted a internet censorship in mainland China contentious Internet sites in mainland China, and Wikimedia sites have been blocked at least thrice in its history. Currently, Wikimedia appears to be undergoing the third block in its history.
The first and so far most significant block lasted between June 2 and June 21, 2004. It began when access to the Chinese Wikipedia from Beijing was blocked on the 15th anniversary of the Tiananmen Square protests of 1989.
Possibly related to this, on .
The first block had an effect on the vitality of Chinese Wikipedia, which [http://en.wikipedia.org/wikistats/EN/TablesWikipediaZH.htm suffered sharp dips in various indicators] such as the number of new users, the number of new articles, and the number of edits. In some cases, it took anywhere from 6 to 12 months in order to regain the stats from May 2004.
The second and less serious outage lasted between September 23 and September 27, 2004. During this 4-day period, access to Wikipedia was erratic or unavailable to some users in mainland China — this block was not comprehensive and some users in mainland China were never affected. The exact reason for the block is a mystery, but it may have been linked with the closing down of YTHT BBS, a popular Peking University-based BBS that was shut down a few weeks earlier for hosting overtly radical political discussions. Refugees from the BBS had arrived en masse on Chinese Wikipedia. Chinese Wikipedians once again prepared a written appeal to regional ISPs, but the block was lifted before the appeal was actually sent out; the reasons of which are, once again, a mystery.
The third block began on that they can only access Wikipedia using proxy servers.
