Step-by-step explanation:
began with its first edit on 15 January 2001, two days after the domain was registered[2] by Jimmy Wales and Larry Sanger. Its technological and conceptual underpinnings predate this; the earliest known proposal for an online encyclopedia was made by Rick Gates in 1993,[3] and the concept of a free-as-in-freedom online encyclopedia (as distinct from mere open source)[4] was proposed by Richard Stallman in December 2000.[5]
The English edition of Wikipedia has grown to 6,215,986 articles, equivalent to around 2,800 print volumes of the Encyclopædia Britannica. Including all language editions, Wikipedia has 55,510,003 articles, equivalent to around 20,800 print volumes.[1]

Crucially, Stallman's concept specifically included the idea that no central organization should control editing. This characteristic greatly contrasted with contemporary digital encyclopedias such as Microsoft Encarta, Encyclopædia Britannica, and even Bomis's Nupedia, which was Wikipedia's direct predecessor. In 2001, the license for Nupedia was changed to GFDL, and Wales and Sanger launched Wikipedia using the concept and technology of a wiki pioneered in 1995 by Ward Cunningham.[6] Initially, Wikipedia was intended to complement Nupedia, an online encyclopedia project edited solely by experts, by providing additional draft articles and ideas for it. In practice, Wikipedia quickly overtook Nupedia, becoming a global project in multiple languages and inspiring a wide range of other online reference projects.
Wikipedia's worldwide monthly readership is approximately 495 million.[7] Worldwide in September 2018, WMF Labs tallied 15.5 billion page views for the month.[8] According to comScore, Wikipedia receives over 117 million monthly unique visitors from the United States alone.[9]
