It was released in 1977, shortly after Nintendo's Color TV-Game 6 console earlier that year the Color TV-Game featured 15 games though they were all variations of "Light Tennis" and added wired controllers which the previous model (the Color TV-Game 6) did not have.
It was succeeded by the Color TV-Game Racing 112, with a racing wheel controller and gear stick, in 1978. It was the first video game product designed by Shigeru Miyamoto. It featured vertical scrolling graphics, similar to the Speed Race series of arcade games.
The three above consoles were produced in collaboration with Mitsubishi. The first console produced entirely by Nintendo was the Color TV Block Kusure, released in 1979, also designed by Shigeru Miyamoto.
The Color TV Game series sold 3 million units in Japan. It was eventually succeeded by the Famicom/NES in 1983.
