Nintendo's near monopoly on the home video game market left it with a degree of influence over the industry. Unlike Atari, which never actively courted third-party developers (and even went to court in an attempt to force Activision to cease production of Atari 2600 games), Nintendo had anticipated and encouraged the involvement of third-party software developers; strictly, however, on Nintendo's terms. Some of the Nintendo platform-control measures were adopted by later console manufacturers such as Sega, Sony, and Microsoft, although not as stringent.

Who did Atari attempt to force ceasing production of games for its system?
