The Intellivision is a home video game console released by Mattel Electronics in 1979. The name is a portmanteau of "intelligent television". Development began in 1977, the same year as the launch of its main competitor, the Atari 2600. In 1984, Mattel sold its video game assets to a former Mattel Electronics executive and investors, eventually becoming INTV Corporation. Game development ran from 1978 to 1990, when the Intellivision was discontinued. From 1980 to 1983, more than 3.75 million consoles were sold. As per Intellivision Entertainment the final tally through 1990 is somewhere between 4.5 and 5 million consoles sold.

A home video game console is a video game console that is designed to be connected to a display device, such as a television, and an external power source as to play video games. While initial consoles were dedicated units with only a few games fixed into the electronic circuits of the system, most consoles since support the use of swappable game media, either through game cartridges, optical discs, or through digital distribution to internal storage.
