Atari Games continued to manufacture arcade games and, starting in 1987, also sold cartridges for the Nintendo Entertainment System under the Tengen brand name, including a version of Tetris. The companies exchanged a number of lawsuits in the late 1980s related to disputes over the rights to Tetris and Tengen's circumvention of Nintendo's lockout chip, which prevented third parties from creating unauthorized games. (Atari Games' legal battles with Nintendo should not be confused with those of its former parent company--Atari also exchanged lawsuits with Nintendo in the late 1980s and early 1990s.)
In 1989, Time-Life bought Warner Communications, forming Time Warner. In 1993 Time Warner once again bouth a controlling interest in the company and changed the name of Atari Games to Time Warner Interactive (TWI). In 1996, TWI was sold to WMS Industries (owners of the Williams, and Bally/Midway arcade brands) and reverted back to the name Atari Games. When Hasbro Interactive resurrected the Atari name in the home software arena, Atari Games was renamed Midway Games West to avoid confusing the two brands. Midway Games left the arcade market to concentrate on home systems in 2001, ending Atari's pivotal influence in the arcade industry. Midway Games West, still producing games for home systems, was disbanded in 2003.
