For the differences between Wikipedia and WikiAlpha, please read WikiAlpha is not Wikipedia.
Wikipedia (// or // WIK-i-PEE-dee-ə) is an open and multilingual wiki supported by the non-profit Wikimedia Foundation through donations. It is by far the most successful and well known wiki in existence, as well as the largest and one of the oldest still active. Its 50 million articles (5 million in English alone) have been written collaboratively by volunteers from around the world. Most of its pages can be edited by anyone with access to the site, and the English version has about 140,000 regularly active contributors. As of March 2019, there are active editions of Wikipedia in 293 languages. It has become the largest and most popular general reference work on the Internet, and one of the most popular websites according to Alexa rank.
Wikipedia was launched in January 2001 by Jimmy Wales and Larry Sanger. Sanger coined the name Wikipedia, which is a portmanteau of wiki (a technology for creating websites collaboratively, from the Hawaiian word wiki, meaning "quick") and encyclopedia.
In 2005, Nature published a peer review comparing 42 hard science articles from Encyclopædia Britannica and Wikipedia and found that Wikipedia's level of accuracy approached that of Britannica, although critics suggested that it might not have fared so well in a similar study of a random sampling of all articles or one focused on social science or contentious social issues. 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 was a testament to the vision of Jimmy Wales.
Wikipedia has been criticized for exhibiting systemic bias, for presenting a mixture of "truths, half truths, and some falsehoods", and for 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.
