Coleco's first entry into the video game market was hard-wired consoles that came with only one game built in, such as the ever-popular Pong. They also released a series of hand-held games featuring various sports and licensed arcade titles. Then in 1982 the ColecoVision hit the market with a bang. Much more powerful than the Atari 2600, the ColecoVision was capable of arcade-quality ports of popular arcade games, bringing a new level of experience to the home video gamer. Their near-perfect port of Donkey Kong came with the console and provided a huge boost to sales. Coleco also released an expansion to make their console compatible with Atari 2600 games, giving them by far the largest effective game library available on the market at that time.
