"Quake is a first-person shooter video game that was released by id Software on June 22, 1996. It was the first game in the popular Quake series of video games. Quake was released just as the Internet was reaching maturity, and much of its popularity arose because it was one of the few games of its kind playable over the internet rather than just a local network."
