Company Information
At the beginning of 1980 Mattel's video game console "Intellivision" came on the market and was a direct competitor of the Atari VCS. From 1980 to 1983, Mattel produced and sold versions of its Intellivision games for the Atari VCS console under the label "M Network", but some of them under a different name (e.g. the game "Astrosmash" in the Atari version was renamed "Astroblast").
Atari was initially not allowed to make games for the Intellivision in return. In the early 1980s, Mattel filed a lawsuit against Atari because it was alleged that former Mattel employees who had worked for Atari betrayed trade secrets. Probably one reason why Atarisoft ultimately produced only three games for the Intellivision console (Centipede, Defender, Pac-Man, all 1983).
