In 1982, Mattel released the Intellivision II,a cut price model of the origional, to the market. It was much smaller and cheaper to produce, it also tried to introduce a change to the ROM to lock out unlicensed 3rd party software which affected a few of Coleco's early games for the Intellivision. The Intellivision II also had minor changes to the sound chip which resulted in errors with a few sound effects in some games. The new machine was a direct result of increasing competition from not only Atari, but also Coleco and Milton Bradley.

The cartridge port of the Intellivision II had a functual change with the addition of video input. This design was added to specifically support the System Changer, an accessory that played Atari 2600 cartridges. The Intellivision II also had controller ports compatible with Atari joysticks.

Late in 1983, Mattel’s electronics division posted losses in the hundreds of millions, caused by falling sales, increased competition, and a lack of big name titles. The division closed in 1984, and a liquidator purchased the rights to the Intellivision name and software stocks. After the software was exhausted, Terry Valeski, a former Mattel director bought all rights to Intellivision and started a new venture.

The new company, INTV Corp., continued to sell old stock via retail and mail order. When the old stock of Intellivision II consoles ran out, they introduced a new console dubbed INTV System III. This unit was a cosmetic rebadge of the original Intellivision console (this unit was later renamed the Super Pro System).

In addition to manufacturing new consoles, INTV Corp. also continued to develop new games, releasing a few new titles each year. Eventually, the system was discontinued in 1991.
