Wikipedia is a free-content online encyclopedia written and maintained by a community of volunteers, collectively known as Wikipedians, through open collaboration and using a wiki-based editing system called MediaWiki. Wikipedia is the largest and most-read reference work in history, and has consistently been one of the 10 most popular websites. Created by Jimmy Wales and Larry Sanger on January 15, 2001, it is hosted by the Wikimedia Foundation, an American nonprofit organization.
Initially available only in English, versions in other languages were quickly developed. Wikipedia's combined editions comprise more than articles, attracting around 2 billion unique device visits per month and more than 15 million edits per month (about 5.8 edits per second on average) .
Wikipedia has been praised for its enablement of the democratization of knowledge, extent of coverage, unique structure, and culture. It has been criticized for exhibiting systemic bias, particularly gender bias against women and geographical bias against the Global South. While the reliability of Wikipedia was frequently criticized in the 2000s, it has improved over time, receiving greater praise in the late 2010s and early 2020s, having become an important fact-checking site. It has been censored by world governments, ranging from specific pages to the entire site. Articles on breaking news are often accessed as a source of frequently updated information about those events.
History of Wikipedia
Nupedia
Various collaborative online encyclopedias were attempted before the start of Wikipedia, but with limited success. Wikipedia began as a complementary project for Nupedia, a free online English-language encyclopedia project whose articles were written by experts and reviewed under a formal process. It was founded on March 9, 2000, under the ownership of Bomis, a web portal company. Its main figures were Bomis CEO Jimmy Wales and Larry Sanger, editor-in-chief for Nupedia and later Wikipedia.

Wikinews is a free-content news wiki and a project of the Wikimedia Foundation that works through collaborative journalism. Wikipedia co-founder Jimmy Wales has distinguished Wikinews from Wikipedia by saying, "On Wikinews, each story is to be written as a news story as opposed to an encyclopedia article." Wikinews's neutral point of view policy aims to distinguish it from other citizen journalism efforts such as Indymedia and OhmyNews. In contrast to most Wikimedia Foundation projects, Wikinews allows original work in the form of original reporting and interviews.
