The Atari 7800 ProSystem, or simply the Atari 7800, is a video game console re-released by Atari Corporation in January 1986. The original release had occurred two years earlier under Atari Inc. The 7800 had originally been designed to replace Atari Inc.'s Atari 5200 in 1984, but was temporarily shelved due to the sale of the company after the video game crash. In January 1986, the 7800 was again released and would compete that year with the Nintendo Entertainment System and the Sega Master System. It had simple digital joysticks and was almost fully backward-compatible with the Atari 2600, the first console to have backward compatibility without the use of additional modules. It was considered affordable at a price of US$140.
In 2009, IGN chose the 7800 to be their 17th best video game console of all time. They justified this relatively low ranking (though higher than every other Atari console save the 2600) with the summary statement: "Its delayed release, its cancelled peripherals, and a lack of financial backing from the company's new owners all combined to ensure that Atari 7800 would never see any success beyond being a sexier way of playing Atari 2600 titles."
