Content
Wikipedia ( i/ˌwɪkᵻˈpiːdiə/ or i/ˌwɪkiˈpiːdiə/ WIK-i-PEE-dee-ə) is a free-access, free-content
Internet encyclopedia, supported and hosted by the non-profit Wikimedia Foundation. Those
who can access the site can edit most of its articles.[5] Wikipedia is ranked among the ten most
popular websites,[4] and constitutes the Internet's largest and most popular general reference
work.[6][7][8]
Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001. Sanger[9] coined its
name,[10] a portmanteau of wiki[notes 3] and encyclopedia. Initially only in English, Wikipedia
quickly became multilingual as it developed similar versions in other languages, which differ in
content and in editing practices. The English Wikipedia is now one of 291 Wikipedia editions
and is the largest with 5,057,816 articles (having reached 5,000,000 articles in November 2015).
There is a grand total, including all Wikipedias, of over 38 million articles in over 250 different
languages.[12] As of February 2014, it had 18 billion page views and nearly 500 million unique
visitors each month.[13]
A peer review of 42 science articles found in both Encyclopædia Britannica and Wikipedia was
published in Nature in 2005, and found that Wikipedia's level of accuracy approached
Encyclopedia Britannica' s.[14] Criticisms of Wikipedia include claims that it exhibits systemic
bias, presents a mixture of "truths, half truths, and some falsehoods",[15] and that in controversial
topics it is subject to manipulation and spin.[16]
