In the beginning, there was Creationism.

The much-debated belief that a supreme being created the physical universe was the most-edited article in Wikipedia’s first year, 2001. But in the genesis of the open-sourced encyclopedia powered by the world, that didn’t amount to a lot of edits: just 179 edits made it the top article for all of Wikipedia’s first year.

As Wikipedia turns 15 on Friday, things have evolved a great deal. The English-language Wikipedia is just one of many Wikimedia projects today, and its 5,053,647 articles have now been edited 808,187,367 times (as of press time). Parsing those edits by year brings into focus a fascinating evolution of the current millennia online, revealing not just what people clicked on or read or even shared. The most-edited articles show what Wikipedians created and shaped and gave to the world as this millennia began to unfold.

The most-edited article this past year, Deaths in 2015, inspired 18,271 edits[1]—more than 100 times the total that put creationism on top 15 years ago. Deaths in [year] are staples in the English Wikipedia’s editing history; they are the most-edited articles in each year between 2007 and 2015, and the second-most in 2001, 2003, and 2006. As such, we’ve mostly omitted them in the list.

Obituaries of the year show up through the list of each year’s most-edited articles, but some surprises and zeitgeist zings also pop up among the most edited articles in each of Wikipedia’s 15 years. The aggregate list from all 15 years follows at the bottom.

Our thanks go to Stephen LaPorte for obtaining the year-by-year data. You can see the full list on Hatnote.

2015: And last year’s most-edited stories proved once again that Wikipedia can still be zany, despite all its accomplishments. While Deaths of the year was still the most-edited story, Geospatial summary of the High Peaks/Summits of the Juneau Icefield was #2—one editor made 7,265 edits, and everyone else made 29.

Most-edited articles of all time

After getting the data for each year, we wondered what the most-edited articles on the English-language Wikipedia for all 15 of its years. It turns out that it’s a controversial president who served for eight years, followed by wrestlers.

George W. Bush, 2004 and 2005’s most edited article, topped this list—an unsurprising place, given that it’s was named as the most controversial topic on the English Wikipedia in Global Wikipedia, published in 2014. Several other articles on this list are mirrored on the most controversial list, such as list of World Wrestling Entertainment, Inc. personnel, which came in second by only a few thousand edits. History comes up with Adolf Hitler and World War II, while religion includes the Catholic Church and the article for Jesus.

Of course, Wikipedia’s oddities also spring up. While Britney Spears is a world-famous music artist, one would probably not put her into world history alongside the Catholic Church, Adolf Hitler, or World War II. Also making appearances is the list of programs broadcast by ABS-CBN, one of oldest television stations in Asia and the first in the Philippines, and Wikipedia’s meta article on itself

You can see more of this data on the English Wikipedia; sort by namespace zero.
