First Successful Video Game Console Using Plug-in Cartridges (1977)

Nolan Bushnell and Atari, Sunnyvale, California, introduced the Atari Video Computer System ( VCS).

Later known as the Atari 2600, VCS was the first successful video game console to use plug-in cartridges instead of having one or more games built in. It was "typically bundled with two joystick constrollers, a conjoined pair of paddle controllers, and a cartridge game."
