The Game Boy is an 8-bit, fourth generation, handheld game console developed by Nintendo, launched in the Japanese home market on April 21, 1989, followed by North America and Europe later that year. Designed by the team behind the Game & Watch handhelds and NES games, it was Nintendo's first portable console, combining features from both.

One of the many criticisms for the original Game Boy was its lack of a backlight, so many third-party accessories were created to make play possible in low-light conditions.
Fourth generation of video game consoles
In the history of video games, the fourth generation of video game consoles, more commonly referred to as the 16-bit era, began on October 30, 1987, with the Japanese release of NEC Home Electronics' PC Engine. Though NEC released the first console of this era, sales were mostly dominated by the rivalry between Sega and Nintendo across most markets: the Sega Mega Drive and the Super Nintendo. Cartridge-based handheld game consoles became prominent during this time, such as the Nintendo Game Boy, Atari Lynx, Sega Game Gear and TurboExpress.
