Atari Video Computer System (1977)

 Later known as the Atari 2600, the VCS brought video games out of the arcade and into America's living rooms. It was a snap to set up: Just plug the clunky-looking box into your TV set and grab the joystick. The Atari 2600 was the first successful console to use game cartridges, which allowed consumers to play multiple games on the same system and created a huge market for crude-looking but addictive titles such as Space Invaders and Pac Man. The Atari's games may not have looked much like Grand Theft Auto, but its influence can be felt in today's Xboxes, PlayStations, and GameCubes.
