Midway Games West, Inc.
Atari Games Corporation was a subsidiary of Time Warner Communications. It was founded in 1985 after Time Warner sold the console and computer divisions of Atari, Inc. (which continued operations as Atari Corporation). Atari Games Corporation kept Atari's arcade business.
Warner Communications sold off its controlling interest to Namco in 1985 (which were bought back by Atari employees in 1986). At this time, the company founded Tengen, Inc. to get foot into the console market.
Time Warner bought the controlling interest back in 1993 and made the company a subsidiary of Time Warner Interactive, Inc.. In 1996 it was sold to WMS Industries which made it a subsidiary or Midway Games, Inc. and renamed it to Midway Games West, Inc. in 1999.
It remained in the arcade business until 2001 and was closed in 2003. However, the entity was not dissolved until 2013 (and, along with the rest of Midway, became property of Warner Bros. Entertainment in 2009).
