Atari, Inc. is an American video gaming company based in New York City, and a subsidiary of the Atari SA holding company. It is the main entity serving the commercial Atari brand globally since 2003. The company currently publishes games based on retro Atari franchises as well as some new content, and also produces the new Atari 2600+ console. In the past it produced titles including Neverwinter Nights, Driver 3, Fahrenheit, RollerCoaster Tycoon 3 and Test Drive Unlimited.

Its origins date to GT Interactive Software in 1993, known for publishing games such as Doom II, Quake, Driver, the first Unreal. The company was acquired by Infogrames in 1999, and later renamed to Infogrames, Inc. Two years after Infogrames’s purchase of the Atari brand and assets from Hasbro Interactive, the company was rebranded to Atari, Inc., initially serving as Infogrames’s US operations. In 2008 it became a wholly-owned subsidiary of Infogrames, now known as Atari SA, and activities were largely consolidated into Atari Inc.
