Released in 1982, the ColecoVision was infamous for advertising games using doctored or artist renditions of screenshots designed to look like a completed game. Various other advertised games were never even released.
Other problems: Coleco Industries tried to do too much and made a hardware expansion module (the Adam), turning the console into a full blown computer. Consumers balked at the $600 price tag, despite the Adam containing a new Digital Data Pack, which were higher capacity than older audio cassette drives. The failure weakened Coleco, which eventually filed for bankruptcy.
