What is an Intellivision? The Intellivision is a home video game system that was released in 1979 by Mattel Electronics. It was a direct competitor of the Atari 2600. Games for the system were still being released into the early 1990's. A total of over 3 million Intellivision consoles were sold worldwide. Today the Intellivision has a very active aftermarket gaming scene with new games being released each year. A new Intellivision home console will be released in late 2020 named the Intellivision Amico™ and will continue the legacy.
