Wikipedia is a collaboratively edited, multilingual, free Internet encyclopedia supported by the non-profit Wikimedia Foundation. Wikipedia’s 30 million articles in 287 languages, including over 4.3 million in the English Wikipedia, are written collaboratively by volunteers around the world. Almost all of its articles can be edited by anyone having access to the site. It is the largest and most popular general reference work on the Internet, ranking seventh globally among all websites on Alexa as of July 2013, and having an estimated 365 million readers worldwide.

Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger. Sanger coined the name Wikipedia, which is a portmanteau of wiki (a type of collaborative website, from the Hawaiian word wiki, meaning “quick”) and encyclopedia.
