Wikipedia is a free encyclopedia, written collaboratively by the people who use it. It is a special type of website designed to make collaboration easy, called a wiki. Many people are constantly improving Wikipedia, making thousands of changes per hour.


Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger.[11] Sanger[12] coined its name,[13] a portmanteau of wiki[notes 4] and encyclopedia. There was only the English language version initially, but it quickly developed similar versions in other languages, which differ in content and in editing practices. With 5,299,486 articles, the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias. Overall, Wikipedia consists of more than 40 million articles in more than 250 different languages[15] and as of February 2014, it had 18 billion page views and nearly 500 million unique visitors each month.[16]
