IGN (formerly Imagine Games Network) is an American video game and entertainment media website operated by IGN Entertainment Inc., a subsidiary of Ziff Davis, Inc. The company's headquarters is located in San Francisco's SoMa district and is headed by its former editor-in-chief, Peer Schneider. The IGN website was the brainchild of media entrepreneur Chris Anderson and launched on September 29, 1996. It focuses on games, films, anime, television, comics, technology, and other media. Originally a network of desktop websites, IGN is also distributed on mobile platforms, console programs on the Xbox and PlayStation, FireTV, Roku, and via YouTube, Twitch, Hulu, and Snapchat.

Originally, IGN was the flagship website of IGN Entertainment, a website which owned and operated several other websites oriented towards players' interests, games, and entertainment, such as Rotten Tomatoes, GameSpy, GameStats, VE3D, TeamXbox, Vault Network, FilePlanet, and AskMen, among others. IGN was sold to publishing company Ziff Davis in February 2013 and operates as a J2 Global subsidiary.
