INTV Corporation

INTV Corporation was an American console and game development company formed by a former Mattel marketing executive after purchasing the rights to Intellivision in 1984. The company released the upgraded INTV System III console, also known as the Intellivision Super Pro System, and produced another 21 Intellivision games, until 1990, when it discontinued the Intellivision in favor of contracting to produce games for Nintendo and Sega. The company, at this time, also contracted with World Book to produce an educational console system called Tutorvision. The company folded in 1991 in the wake of legal disputes with World Book, and Tutorvision was never released.
