GI published an updated chipset in its 1978 catalog.

The GI chipset lacked reprogrammable graphics and Mattel worked with GI to implement changes. Its consultant, APh Technological Consulting, suggested a General Instrument chipset, listed as the Gimini programmable set in the GI 1977 catalog. Mattel identified a new but expensive chipset from National Semiconductor and negotiated better pricing for a simpler design. It was to have rich graphics and long lasting gameplay to distinguish itself from its competitors. Mattel's Design and Development group began investigating a home video game system in 1977. The Intellivision was developed at Mattel in Hawthorne, California, along with the Mattel Electronics line of handheld electronic games. It remained Mattel's only video game console until the HyperScan in 2006. 14 of the greatest video game consoles of all time.

In 1984, Mattel sold its video game assets to a former Mattel Electronics executive and investors, eventually becoming INTV Corporation.
