It uses a wiki content management system and is the largest and most popular general reference work on the World Wide Web; According to Alexa Internet service from June 2019, it is one of the most popular websites ever. It contains exclusively free content and does not contain any commercial advertisements. Wikipedia is owned and supported, like other interconnected projects, by the Wikimedia Foundation, a non-profit organization that is funded primarily through donations. Wikipedia was launched on January 15, 2001 by Jimmy Wales and Larry Sanger. Her name was suggested by Larry Sanger, as a combination of the words "wiki" (Hawaiian word for "fast") and "encyclopedia". Initially, only the English language version worked, but soon other language versions emerged. The Czech version was launched on May 3, 2002. In total, Wikipedia contained more than 55.5 million articles in more than 300 different languages ​​in January 2021, and in February 2014 it reached 18 billion page views and almost 500 million unique visitors per month. .wiki, which means that a new article can be inserted and any article can be changed (whether you just correct a typo, correct a factual error, significantly expand the article or completely rewrite it) almost anyone with access to the site. One of the basic rules enforced by users is the so-called unbiased point of view - articles must present impartially all the essential views on the topic, without pretending to be the only objective truth. The requirement for data verifiability in the articles is applied in particular to controversial data and topics.

History and scope

The germ of Wikipedia originated in 1995, when programmer Ward Cunningham founded a website called WikiWikiWeb, which could be customized by every visitor - since then, similar systems, now referred to as wiki, are the Hawaiian word for "fast", meaning sites where a visitor can anything quickly fix) appeared a large amount. They are very often used, for example, as an in-house knowledge base. Wikipedia as such was created on January 15, 2001 as a supplementary project to the now defunct encyclopedia Nupedia, to which only experts could contribute. The founders of both projects were Americans Jimmy Wales (nicknamed Jimbo), an internet entrepreneur, and Larry Sanger, a philosopher and computer scientist who soon left Wikipedia. On June 20, 2003, Wales established the Wikimedia Non-Profit Foundation under the laws of the State of Florida (USA), to which it transferred copyright and ownership rights related to Wikipedia and sister projects. At the end of 2004, Sanger launched a debate criticizing anti-elitism, which discourages experts from cooperating, and in 2006 he founded his own project, Citizendium, to remedy this shortcoming. Wikipedia's popularity continues to grow. Gradually, several sister projects were created next to it. Wikipedia is one of the most popular reference pages on the web, serving approximately 60 million requests every day. In June 2013, it was ranked 7th among all websites in terms of the number of visits. The German version of Wikipedia was published on CD, and a thousand-page selection of about 20,000 articles on German Wikipedia was also published in September 2008 by Das Wikipedia-Lexikon in einem Band in collaboration with the respected publishing group Bertelsmann. There are a large number of servers on the Internet that offer copies of Wikipedia content under the terms of the GFDL. In May 2005,
