The Color TV-Game is the first video game system ever made by Nintendo. The system was released as a series of five dedicated home video game consoles between 1977 and 1983 in Japan only. 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 all the first generation of video game consoles.

Nintendo Research & Development No. 2 Department, commonly abbreviated as Nintendo R&D2, was a Japanese team within Nintendo that developed software and peripherals. While usually occupied in system operating software and technical support, the team would come back to early development in the 1990s where several new designers got their start at game development, the most famous being Eiji Aonuma who developed Marvelous: Another Treasure Island.
