Wikipedia recently celebrated its 15th birthday. The online encylopaedia has grown to over 5 million entries and anybody can edit them. In fact, the English language version of the website has attracted around 808 million edits over the course of its lifespan.
George W. Bush is the most edited Wikipedia topic entry of all time with just under 46,000 edits. (Internal communications pages actually dominate Wikipedia’s list of the pages with the most revisions.) George W. Bush’s page is also the most edited entry in a single year, according to numbers obtained by 538, with people tweaking it 20,894 times in 2005. 2015′s most edited article was a little more obscure. “Geospatial summary of the High Peaks/Summits of the Juneau Icefield” grabbed top spot last year with 7,290 edits.
