Game Boy Color is an 8-bit handheld console released by Nintendo in 21 of October, 1998 and in November of the same year in the other markets. It is the successor of the Game Boy and it's variants, Game Boy Pocket and Game Boy Light. It is also cartridge based and the first handheld console with backwards compatibility for its games. With a palette of 32,768 colors it's the first Game Boy with colored screen but with no backlit. It is a little thicker and taller than the Game Boy Pocket and has a smaller screen.
Game Boy Color dominated the market as its predecessor, Game Boy. The direct competitors of the console was the 16-bit consoles SNK's Neo Geo Pocket and Bandai's WonderSwan and their next models Neo Geo Pocket Color and WonderSwan Color. However, the difference was quite huge. Game Boy and it's variants along with the Game Boy Color sold 118.69 million units. The most successful games of the console were Pokemon Gold and Silver with 23 million units sold. One of the facts that helped a lot was the backwards compatibility with the Game Boy games since the console had a huge advantage in the numbers of its game library. In 23 of March, 2003 it discontinued as the best selling console, a little bit after the launch of Game Boy Advance SP. Only Nintendo DS and Playstation 2 managed to have better sales than Game Boy Color until now.
