The English Wikipedia is the English-language edition of the free online encyclopedia Wikipedia. Founded on 15 January 2001, it is the first edition of Wikipedia and, as of November 2015, has the most articles of any of the editions. As of April 2016, nearly % of articles in all Wikipedias belong to the English-language edition. This share has gradually declined from more than 50 percent in 2003, due to the growth of Wikipedias in other languages. There are articles on the site (live count). In October 2015, the combined text of the English Wikipedia's articles totalled 11.5 gigabytes when compressed. On November 1, 2015, the English Wikipedia announced it had reached 5,000,000 articles and ran a special logo to reflect the milestone.
