1979 - Mattel Intellivision
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 went nationwide in 1980 with a price tag of US$299 and a pack-in game: Las Vegas Poker & Blackjack.

In that first year Mattel sold 175,000 Intellivision consoles, and the library grew to 19 games. At this point in time, all Intellivision games were developed by an outside firm, APh. The company recognized that what had been seen as a secondary product line might be a big business. Realizing that potential profits are much greater with first party software, Mattel formed its own in-house software development group.

It is said that more than 6 million Intellivision consoles were sold during its 12 year run and there were a total of 125 Intellivision games released.
