Wikipedia

Wikipedia is a free-content online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and the wiki software MediaWiki. Wikipedia is the largest and most-read reference work in history, and is consistently ranked among the ten most visited websites; as of December 2024, it was ranked fifth by Semrush, and seventh by Similarweb. Founded by Jimmy Wales and Larry Sanger on January 15, 2001, Wikipedia has been hosted since 2003 by the Wikimedia Foundation, an American nonprofit organization funded mainly by donations from readers. Initially only available in English, Wikipedia now exists in more than 300 languages. The English Wikipedia, with over 6.9 million articles, remains the largest of the editions, which together comprise more than 64 million articles and attract more than 1.5 billion unique device visits and 13 million edits per month (about 5 edits per second on average) as of April 2024. As of November 2024, over 25% of Wikipedia's traffic was from the United States, followed by Japan at 6.2%, the United Kingdom at 5.6%, Russia at 5.0%, Germany at 4.8%, and the remaining 53.3% split among other countries. Wikipedia has been praised for its enablement of the democratization of knowledge, extent of coverage, unique structure, and culture. Wikipedia has been censored by some national governments, ranging from specific pages to the entire site. Although Wikipedia's volunteer editors have written extensively on a wide variety of topics, the encyclopedia has been criticized for systemic bias, such as a gender bias against women and geographical bias against the Global South (Eurocentrism). While the reliability of Wikipedia was frequently criticized in the 2000s, it has improved over time, receiving greater praise from the late 2010s onward while becoming an important fact-checking site. Articles on breaking news are often accessed as sources for frequently updated information about those events.
