Mattel canned their electronics division in 1984 after the previously noted crash of 1983. A group of former employees formed INTV corporation and bought the rights to the Intellivision.
When the NES was released in 1985 it sparked a resurgence in the game industry. Stores started carrying a limited supply of Intellivision and Atari games again.
In response, INTV corporation dusted-off a few unfinished games in time for the 1987 holiday season. Tower of Doom was one of the most advanced adventure games for the the Intellivision, even rivaling AD&D Treasure of Tarmin. OK, I guess there were only three adventure games for the Intellivision but they were all top-notch. Diner, which I actually owned at the time, was the sequel to Burgertime based on the code for an unfinished He-Man game. Dig-Dug was a so-so port of the arcade game. It was originally written, but not released, in 1984. As a result it was inferior to the more recently published Atari 7800 version.
The last three Intellivision games were produced in 1989. By then the system and games were only available through mail order. The Christmas of 1987 marked the last time new Intellivision games graced store shelves.
