GameSpy

GameSpy was an American provider of online multiplayer and matchmaking middleware for video games founded in 1995 by Mark Surfas. After the release of a multiplayer server browser for Quake, 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.
