Championship Tennis was started at Mattel Electronics to be a one- to four-player game for the Entertainment Computer System (ECS). Ray Kaestner (BurgerTime) started working on the game briefly at Mattel Electronics headquarters in California, but when he was put on Masters of the Universe II, Doubles Tennis was sent to the French office.
A very preliminary version of the cartridge was shown at the January 1984 Consumer Electronics Show. As with World Cup Soccer, when Mattel Electronics closed, the rights to the unfinished game were given to Nice Ideas, the company formed from the French office.
Nice Ideas completed the cartridge as a one- or two- (or zero-) player non-ECS game and it was released in Europe by Dextell Ltd. INTV Corp. negotiated the rights to distribute the cartridge in the United States, introducing it in Spring 1986.
