GameSpy was a provider of online multiplayer and matchmaking middleware for video games. The company originated from a Quake fan site founded by Mark Surfas in 1996; 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 was acquired by IGN in 2000; 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 shutdown date didn't occur until July 16, 2014, however.
GameSpy and the Medal of Honor Allied Assault trilogy
All three games (MoHAA, Spearhead and Breakthrough) of the MoHAA trilogy heavily relied on the GameSpy service. All game servers were configured to tell their status to the GameSpy master servers. When players were browsing for game servers in the corresponding game, the GameSpy master servers were called to get a list of available servers.
Due to the shutdown in July 2014, no game servers are listed anymore in GameSpy related games. That is why the MoHAAS.net community has released the MoHAAS.net tool in order to help players to find game servers.
