Introduced in 1982 by Atari as a replacement for the Atari 2600. The 5200 was created to compete with the Mattel Intellivision, but wound up directly competing with the Colecovision shortly after its release. Despite this competition and a stuttering economy, the Atari 5200 developed a strong cult following with its library of high-quality games.
