Originally (believe it or not), the COnetticut LEather COmpany started in 1932 with founder Maurice Greenberg making leather components for shoes. His son Leonard set up a workshop in the back of his Dad's shop and produced leather craft kits, as well as wading pools for kids - at one point in the 1960s Coleco was the world's biggest supplier of above-ground swimming pools!
In the 70s they saw what Nolan Bushnell of Atari had done with PONG and decided to create their own cheaper version. This was the Telstar, and sold well, as did later Telstar units, though initial production problems meant over a million had to be scrapped at one point.
Seeing what Atari and Mattel were doing with the VCS and Intellivision, Coleco developed the ColecoVision without telling anyone and released it at a trade show much to everyone's surprise! The unit sold massively well - over 6 million shifted off the shelves in its lifetime, but despite the success (and a spat with Atari over Expansion unit #2) what was originally Expansion #3 became the ADAM.
Failure of the ADAM to a) work reliably and b) capture the market forced Coleco out of the videogame industry and back into toy production, where they produced the Cabbage Patch Dolls before being bought out by Hasbro, who'd also bought Atari!

The Coleco history I've massively abridged above was originally written by DigitalCentury, but they've now been absorbed into the Jones Encyclopedia....the online version of which costs money, so bugger that. Instead a former Coleco UK employee has a site dedicated to STARCOM, which was a Coleco made show in the mid 80s. He's reproduced the history here. Nice one Martin!
