M-Network Collection - Atari 2600 - Action

In the early 1980s, Mattel's Intellivision video game console was a direct competitor to Atari's Video Computer System (VCS), better known as the Atari 2600. Although Mattel designed and produced video game cartridges for their own system, the company surprised the industry by also releasing simplified versions of its games for the 2600 under the M Network label.[2][3][4]
