Color TV-Game(Japanese: カラー テレビゲーム,Hepburn: Karā Terebi-Gēmu?) is a series of five home dedicated consoles, created by Nintendo and sold only in Japan. Nintendo sold three million units of the first four models: one million units of each of the first two models, Color TV-Game 6 and 15; and half a million units of each of the next two models, Block Breaker and Racing 112. The Color TV-Game series has the highest sales figures of the first generation of video game consoles.
The series debuted on June 1st, 1977 with the Color TV-Game 6(カラー テレビゲーム6,Karā Terebi-Gēmu Roku?). The Color TV-Game 6 was jointly developed with Mitsubishi Electronics. It contains six variations of Light Tennis (or Pong). The players control their paddles with dials attached directly to the machine. Additionally, as an alternative to the standard version, a white-colored C battery powered model of the Color TV-Game 6 was introduced. These white colored units had a limited run of only a few hundred units.
On June 8th, 1977,just a week after the TV Game 6, Nintendo released the Color TV-Game 15(カラーテレビゲーム15,Karā Terebi-Gēmu Jū Go?). With the two controllers now on cables (making for much more comfortable play) and 15 slightly different versions of Light Tennis, the CTG 15 yielded sales of more than one million units. Two models of the CTG 15 were released, differing only by a slight color tint change. It appears as an "Assist Trophy" in Super Smash Bros. for Nintendo 3DS and Wii U.
On June 8th,1978, Nintendo released the Color TV-Game Racing 112(カラーテレビゲームレーシング112,Karā Terebi-Gēmu Rēshingu Hyaku Jū Ni?), a bird's-eye-view racing game that implements a steering wheel and gearshift. Alternatively, two smaller controllers can be used for multiplayer.
The "Color TV-Game Block Breaker"(カラーテレビゲームブロック崩し,Karā Terebi-Gēmu Burokku Kuzushi?) was released on April 23rd, 1979; the 1-player console runs a ported version of "Block Breaker" (ブロック崩し,Burokku Kuzushi?), one of Nintendo's arcade games based on Atari's Breakout. Like the Color TV-Game 6, the in-game paddle was controlled by a dial attached to the system. The system's external design was one of Shigeru Miyamoto's first video-game projects after joining Nintendo in 1977.
The final console in the series is the Computer TV-Game(コンピューターテレビゲーム,Konpyūtā Terebi-Gēmu?), released in 1980. One of the games in this console was a port of Nintendo's first video arcade game, Computer Othello.
