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.

China has blocked the Wikipedia domain since 2015

The Chinese language version of the site had been blocked intermittently since 2004 due to pages featuring topics deemed controversial by the Chinese communist party, including the 1989 Tiananmen Square protests and Taiwan. Once Wikipedia switched to an HTTPS protocol—making it impossible to block individual pages—all Wikipedia pages were blocked.

Wikipedia openly displays edit history and editorial disputes to assess trustworthiness

Unlike a journal article, which may be reviewed by up to three people before publication, popular Wikipedia pages may be reviewed thousands of times by editors, potentially enhancing their reliability. Less reviewed articles still require reliable third-party sources and remain subject to verification by bots and administrators who can undo edits.

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.

The software for wikis—user-editable websites—was launched in 1995

Research suggests articles on Wikipedia are about as reliable as 'accurate' sources

Philip Roth once tried to correct details on one of his novel's Wikipedia pages

The Wikipedia entry for Roth's 2000 novel "The Human Stain" alleges that the book was based on the life of Anatole Broyard, a Black American writer who "passed" for white, something he shared in common with the main character in Roth's novel, though Roth said that wasn't true.
