About Wikipedia

Wikipedia (WIK-ih-PEE-dee-ə) is a multilingual, web-based, free encyclopedia that is based on a model of openly editable content. It is the largest and most popular general reference work on the Internet, and is one of the most popular websites by Alexa rank. It is owned and supported by the Wikimedia Foundation , a non-profit organization which operates on money it receives from donors.

Wikipedia was launched on January 15, 2001 by Jimmy Wales and Larry Sanger. Sanger coined its name, a portmanteau of wiki and encyclo pedia . Initially an English-language encyclopedia, versions in other languages were quickly developed. With 5,682,871 articles, the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias. Overall, Wikipedia comprises more than 40 million articles in 301 different languages and had 18 billion page views and nearly 500 million unique visitors each month as of February 2014.

As of March 2017, Wikipedia has about 40,000 Featured Articles and Good Articles that cover vital topics. In 2005, Nature published a peer review comparing 42 science articles from Encyclopædia Britannica and Wikipedia and found that Wikipedia's level of accuracy approached that of Encyclopædia Britannica. Time magazine stated that the open-door policy of allowing anyone to edit had made Wikipedia the biggest and possibly the best encyclopedia in the world and it was testament to the vision of Jimmy Wales.

Wikipedia has been criticized for exhibiting systemic bias, presenting a mixture of "truths, half truths, and some falsehoods", and being subject to manipulation and spin in controversial topics. In 2017, Facebook announced that it would help readers detect fake news by suitable links to Wikipedia articles. YouTube announced a similar plan in 2018. In response, the Washington Post headlined, "Wikipedia, the ‘good cop’ of the Internet".
