The Intellivision is a video game console released by Mattel in 1979. Development of the console began in 1978, less than a year after the introduction of its main competitor, the Atari 2600. The word intellivision is a portmanteau of “intelligent television”. Over 3 million Intellivision units were sold and a total of 125 games were released for the console.

In 2009, video game website IGN named the Intellivision the No. 14 greatest video game console of all time. It became Mattel’s first video game console, though it was their only console until the release of the HyperScan in 2006.

The Intellivision was developed by Mattel Electronics, a subsidiary of Mattel formed expressly for the development of electronic games. The console was test marketed in Fresno, California, in 1979 with a total of four games available, and was released nationwide in 1980 with a price tag of US$299 and a pack-in game: Las Vegas Poker & Blackjack. Though not the first system to challenge Atari, it was the first to pose a serious threat to Atari’s dominance. A series of advertisements featuring George Plimpton were produced, that demonstrated the superiority of the Intellivision’s graphics and sound to those of the Atari 2600, using side-by-side game comparisons.
