Owner Wikimedia Foundation Created by Jimmy Wales, Larry Sanger[2] Launched January 15, 2001; 13 years ago Alexa rank Steady 6 (March 2014)[3] Current status Active Wikipedia (Listeni/ˌwɪkɨˈpiːdiə/ or Listeni/ˌwɪkiˈpiːdiə/ WIK-i-PEE-dee-ə) is a collaboratively edited, multilingual, free Internet encyclopedia that is supported by the non-profit Wikimedia Foundation. Volunteers worldwide collaboratively write Wikipedia's 30 million articles in 287 languages, including over 4.4 million in the English Wikipedia. Anyone who can access the site can edit almost any of its articles, which on the Internet comprise[4] the largest and most popular general reference work.[5][6][7][8][9] On February 9, 2014, The New York Times reported that Wikipedia is ranked fifth globally among all websites stating, "With 18 billion page views and nearly 500 million unique visitors a month, according to the ratings firm comScore, Wikipedia trails just the largest with 1.2 billion unique visitors."[10] Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001, the latter[11] creating its name,[12] a portmanteau of wiki (the name of a type of collaborative website, from the Hawaiian word for "quick")[13] and encyclopedia. Wikipedia's departure from the expert-driven style of encyclopedia-building and the presence of much unacademic content have received extensive attention in print media. In 2006, Time magazine recognized Wikipedia's participation in the rapid growth of online collaboration and interaction by millions of people around the world, in addition to .[14] Wikipedia has also become known as a news source because of the rapid update of articles related to breaking news.[15][16][17] While Wikipedia has had its fair share of good press it has also gotten its fair share of bad as well. The open nature of Wikipedia has caused concerns about its writing,[18][19] the amount of vandalism,[20][21] and the accuracy of information. Some articles contain unverified or inconsistent information,[22] though a 2005 investigation in Nature showed that the 42 science articles they compared came close to the level of accuracy of Encyclopædia Britannica
