IGN is an American global entertainment website that focuses on video games, films, music and other media. IGN's main website comprises several specialty sites or "channels", each occupying a subdomain and covering a specific area of entertainment. Videogame-related channels include PC Games, Wii, Nintendo DS, Nintendo DSi, Nintendo 3DS, iOS (iPhone, iPod Touch, iPad), Xbox 360, PlayStation 2, PlayStation 3, PlayStation Vita, PlayStation Portable, Xbox Live, Wireless, Retro, and Android games.

IGN's corporate parent is IGN Entertainment, which owns and controls separate sites, such as GameSpy, GameStats, VE3D, TeamXbox, Vault Network, FilePlanet and AskMen.

Created in September 1996 as the Imagine Games Network, IGN was founded by publishing executive Jonathan Simpson-Bint and began as five individual websites within Imagine Publishing: N64.com (later renamed ign64.com), PSXPower, Saturnworld, Next-Generation.com and Ultra Game Players Online. In 1998, the network consolidated the individual sites as system channels under the IGN brand. Next-Generation and Ultra Game Players Online were not part of this consolidation; U.G.P.O. dissolved with the cancellation of the magazine, and Next-Generation was put "on hold" when Imagine decided to concentrate on launching the short-lived Daily Radar brand. Then-parent company Snowball.com held an IPO in 2000, which subsequently bombed with the burst of the dot-com bubble.
