Fandom

Fandomis a wiki hosting service that hosts wikis mainly on entertainment topics (i.e., video games, TV series, movies, entertainers, etc.). The privately held, for-profit Delaware company was founded in October 2004 by Wikipedia co-founder Jimmy Wales and Angela Beesley.

Fandom was acquired in 2018 by TPG Inc. and Jon Miller through Integrated Media Co.

Fandom uses MediaWiki, the same open-source wiki software used by Wikipedia. Unlike the Wikimedia Foundation, the nonprofit organization that hosts Wikipedia, Fandom, Inc. operates as a for-profit company and derives its income from advertising and sold content, publishing most user-provided text under copyleft licenses.

The company also runs the associated Fandom editorial project, offering pop-culture and gaming news. Fandom wikis are hosted under the domain fandom.com, which has become one of the top 50 most visited websites in the world, rapidly rising in popularity beginning in the early 2020s. It ranks as the 50th as of October 2023, with 25.79% of its traffic coming from the United States, followed by Russia with 7.76%, according to Similarweb.
