Atari Video Computer System (VCS) console, 1978

The Atari 2600, originally sold as the Atari Video Computer System or Atari VCS is a home video game console from Atari, Inc. Released on September 11, 1977, it is credited with popularizing the use of microprocessor-based hardware and games contained on ROM cartridges, a format first used with the Fairchild Channel F in 1976. The Atari VCS launched with nine cartridges offering simple, low-resolution games in 2 KiB cartridges. The 2600 was bundled with two joystick controllers, a conjoined pair of paddle controllers, and a game cartridge: initially Combat, and later Pac-Man. It helped spawn a multi-billion dollar industry, paving the way for Intellivision, ColecoVision, Nintendo and the Sega Genesis. Atari 2600 sold an estimated 30 million units during its lifespan. It had an introductory price of $199.
