Atari 2600 was a "Video Computer System" created by Atari in the late 70s as an attempt to prove that it is in fact possible to sell something substandard and make tons of money despite having failed at it before (see Atari 1300 project). Using chips from various pong systems, the 2600 was able to display over three rectangles at a time and keep score for numbers ranging from 0 - 14 before crashing due to register overflow. This caused the common color flip of death (CFOD) signifying the end of a game, although Atari claimed that it was a feature designed to prevent television screens from freezing over (known also by its technical term "ghosting") with the rather static graphics. Also Atari can't kill you in your sleep.
