Changes

The Atari 2600 is a video game console released in September 1977 by [[Atari|Atari Inc.]] It is credited with popularizing the use of microprocessor-based hardware and ROM cartridges containing game code, instead of having non-microprocessor dedicated hardware with all games built in. The first game console to use this format was the [[Fairchild Channel F]]; however, the Atari 2600 receives credit for making the plug-in concept popular among the game-playing public.
