Wikipedia has received praise for its enablement of the democratization of knowledge, extent of coverage, unique structure, culture, and reduced amount of commercial bias, but criticism for exhibiting systemic bias, particularly gender bias against women and alleged ideological bias. In 2006, Time magazine stated that the policy of allowing anyone to edit had made Wikipedia the 'biggest (and perhaps best) encyclopedia in the world', and is 'a testament to the vision of one man, Jimmy Wales'. Its combined editions comprise more than 57 million articles, attracting around 2 billion unique device visits per month, and more than 17 million edits per month (1.9 edits per second). Initially available only in English, versions in other languages were quickly developed. Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger Sanger coined its name as a blending of 'wiki' and 'encyclopedia'. It is hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through small donations. A visitor spends an average time on Wikipedia of 3 minutes and 45 seconds each day. It is the largest and most-read reference work in history, and consistently one of the 15 most popular websites ranked by Alexa as of 2021, Wikipedia was ranked the 13th most popular site. Individual contributors, also called editors, are known as Wikipedians. Wikipedia ( / ˌ w ɪ k ɪ ˈ p iː d i ə/ ( listen) wik-ih- PEE-dee-ə or / ˌ w ɪ k i-/ ( listen) wik-ee-) is a free content, multilingual online encyclopedia written and maintained by a community of volunteers through a model of open collaboration, using a wiki-based editing system.
