Fandom is a wiki hosting service which hosts wikis mainly on entertainment. Its domain is operated by Fandom, Inc., a for-profit Delaware company founded in October 2004 by Jimmy Wales and Angela Beesley. Fandom was acquired in 2018 by TPG Capital and Jon Miller through Integrated Media Co.
Fandom uses MediaWiki, the open-source wiki software used by Wikipedia. Fandom, Inc. 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, but some, especially those that focus on subjects other than media franchises, were hosted under wikia.org until November 2021.
