Right. Infogrames bought a stake in the company in 2003, then fully purchased the company in 2008 (then preceded to change their own name from Infogrames to Atari SA). Part of the bankruptcy is because Atari US wants to separate itself from its money-losing parent company. Atari has a very long and complicated history:
*Founded in 1972 by Nolan Bushnell and Ted Dabney
*Sold to Warner Communications (now known as Time Warner after merging with Time Inc. in 1989) in 1976
*Sold the home computer and console division to Jack Tramiel (founder of Coleco) in 1984, who renamed it Atari Corporation. Warner kept the arcade division (renaming it Atari Games) and also had a 20% stake in Atari Corp.
*Merged with disk drive manufacturer JTS in 1996 and became a subsidiary of it
*In 1998 Hasbro bought all the trademarks and IPs of Atari (initially they just wanted to license some of their IPs like Pong, but then saw they could purchase the whole company for just $5 million) and renamed it Atari Interactive, making it part of their Hasbro Interactive unit
*In 2001 Infogrames licensed the Atari name for use in games.
*In 2003, Infogrames purchase part o Atari and renamed their US branch Atari Inc. and the European branch Atari Europe. In 2008 they purchased the remaining shares of the company. In 2009, they renamed their selves Atari SA.
Making things even murkier, in 2009 Namco Bandai purchased a 34% share of Atari Europe.
