History of Wikipedia (Hype Cycle)

Wikipedia is a free online encyclopedia that was launched on January 15, 2001 by Jimmy Wales. By the end of the year, 20,000 articles had been written. Wikipedia’s popularity reached the ''peak of inflated expectations'' around 2006 to 2007, where a record of 1,800 articles per day were written. During 2008 to 2012, Wikipedia declined. Around 30,000 users were lost. Wikipedia reached its plateau of productivity around 2013, averaging 600 new articles per day. Currently, the English Wikipedia alone has around than 5,524,889 articles, 32,365,493 users, and 137,022 active users (users who has at least one edit in the last 30 days).
