GameSpy was an American provider of online multiplayer and matchmaking middleware for video games founded in 1999 by Mark Surfas. After the release of a multiplayer server browser for the game, QSpy, Surfas licensed the software under the GameSpy brand to other video game publishers through a newly established company, GameSpy Industries, which also incorporated his Planet Network of video game news and information websites, and GameSpy.com.
GameSpy merged with IGN in 2004; by 2014, its services had been used by over 800 video game publishers and developers since its launch. In August 2012, the GameSpy Industries division (which remained responsible for the GameSpy service) was acquired by mobile video game developer Glu Mobile. IGN (then owned by News Corporation) retained ownership of the GameSpy.com website. In February 2013, IGN's new owner, Ziff Davis, shut down IGN's "secondary" sites, including GameSpy's network. This was followed by the announcement in April 2014 that GameSpy's service platform would be shut down on May 31, 2014.
The 1996 release of id Software's video game Quake, one of the first 3D multiplayer action games to allow play over the Internet, furthered the concept of players creating and releasing "mods" or modifications of games. Mark Surfas saw the need for hosting and distribution of these mods and created PlanetQuake, a Quake-related hosting and news site. The massive success of mods catapulted PlanetQuake to huge traffic and a central position in the burgeoning game website scene.
Quake also marked the beginning of the Internet multiplayer real-time action game scene. However, finding a Quake server on the Internet proved difficult, as players could only share IP addresses of known servers between themselves or post them on websites. To solve this problem, a team of three programmers (consisting of Joe "QSpy" Powell, Tim Cook, and Jack "morbid" Matthews) formed Spy Software and created QSpy (or QuakeSpy). This allowed the listing and searching of Quake servers available across the Internet.
