Tengen was a video game publisher and developer that was created by arcade game manufacturer Atari Games. After Nintendo nearly single-handedly revived the market in the United States, Atari Games realized that there was still money to be made in home video games after all. Since Atari Corp. was already involved in the home video game market with the 2600 Jr., 7800, and XEGS game consoles, Atari Games chose to create a new brand name to market their games under.
