While Atari boasts a 40 year history, and is tied closely to the pioneering years of the arcade, its name has meant a number of different things across that time thanks to several changes of hands.
The US-based company now called Atari. Inc was GT Interactive when it was founded in 1993. GT Interactive then became Infogrames Inc. in 1999 after French company Infogrames Entertainment acquired controlling interest in it. In 2001, Infogrames Entertainment bought Hasbro Interactive, who had acquired Atari Corporation and its Atari properties three years prior. In 2003, Infogrames Inc. became Atari Inc, now with license to use the Atari name and logo, and in 2008 Infogrames Entertainment completely acquired the company. Then, just to confuse everything that one step further, Infogrames Entertainment renamed itself as Atari, SA in 2009.
