Wikipedia (Listeni/ˌwɪkɨˈpiːdiə/ or Listeni/ˌwɪkiˈpiːdiə/ wik-i-pee-dee-ə) is a free-access, free content Internet encyclopedia, supported and hosted by the non-profit Wikimedia Foundation. Almost anyone who can access the site[5] can edit almost any of its articles. Wikipedia is the sixth-most popular website[4] and constitutes the Internet's largest and most popular general reference work.[6][7][8] As of 2014, it has 18 billion page views and nearly 500 million unique visitors each month.[9]
Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001. Sanger[10] coined its name,[11] a portmanteau of wiki (from the Hawaiian word for "quick")[12] and encyclopedia. Although Wikipedia's content was initially only in English, it quickly became multilingual, through the launch of versions in different languages. All versions of Wikipedia are similar, but important differences exist in content and in editing practices. The English Wikipedia is now one of more than 200 Wikipedias, but remains the largest one, with over 4.6 million articles.
Wikipedia has earned a reputation as a news source because of its rapid updating of articles related to breaking news.[13][14][15] In addition, Wikipedia's high openness compared to previous encyclopedias and its inclusion of much unacademic content have received extensive media attention.
Wikipedia's high openness has also led to some concerns, such as the quality of its writing,[16] vandalism and the accuracy of its information.[17][18] However, while some articles contain unverified or inconsistent information,[19] a 2005 survey of Wikipedia published in Nature based on a comparison of 42 science articles with Encyclopædia Britannica found that Wikipedia's level of accuracy approached Encyclopædia Britannica's and both had similar low rates of "serious errors".[20] As of 2012, the English Wikipedia contained nearly four million articles, over thirty times more than Britannica (about 120,000).[21]
