A 15-year bibliographic analysis identified systematic gender bias across Wikipedia

A 2024 study by the University of Barcelona found that 71.4% of all English biographies that appear on the front page are about men, and approximately one in five editors are women.

Wikipedia arose from a failed, for-profit online encyclopedia

Nupedia was launched in 2000 by internet entrepreneur Jimmy Wales and internet project developer Lawrence Sanger, only publishing articles written by experts after a cumbersome seven-step review process. The two developed Wikipedia to allow the public to write articles for future review, but shifting to self-moderation contributed to Sanger's departure in 2002.
