Atari's VCS (Video Computer System) was the first Atari 8-bit video console, which was later called the 2600. It revolutionized the home video game market by refining the concept of a game system that used interchangeable cartridges. Atari maintained the upper hand in the market in coming years by producing a large selection of cartridges, as well as licensing home versions of popular arcade games and the rights to movies like "ET" and "Raiders of the Lost Ark." The Atari 2600 was on the market until 1990, making it the console with the longest market time in history.
