The Game Boy Color (abbreviated as GBC) is an 8-bit handheld game console developed by Nintendo. It was released in Japan on October 21, 1998, and in international markets the following month. Compared with the original Game Boy, the Game Boy Color features a color TFT screen instead of monochrome, a CPU running at up to twice the speed, and four times as much memory. It is backward compatible with games developed for its predecessor. The Game Boy Color was released during the fifth generation of video game consoles and competed with the WonderSwan and Neo Geo Pocket, and Genesis Nomad.
The handheld is slightly thicker, taller and has a smaller screen than its immediate predecessor, the Game Boy Pocket, but is significantly smaller than the original Game Boy. As with its predecessors, the Game Boy Color has a custom 8-bit processor made by Sharp. The American English spelling of the system's name, Game Boy Color, remains consistent throughout the world.
The Game Boy Color received positive reviews upon release, and was praised for its backwards compatibility with games from its predecessor. It had a relatively brief lifespan, being succeeded by the Game Boy Advance after less than three years on the market. The Game Boy and the Game Boy Color combined have sold 118.69 million units worldwide, making them the fourth best-selling system of all time. Its best-selling games are Pokémon Gold and Silver (1999), which shipped 23 million units worldwide.
