The GameBoy is an 8-bit handheld game console developed and manufactured by Nintendo. The first handheld in the GameBoy family. It was first released in Japan on April 21, 1989. The console was released in North America later the same year. Then in Europe in late 1990. It was designed by the same team that developed the Game & Watch series of handheld electronic games and several Nintendo Entertainment System games: Satoru Okada, Gunpei Yokoi, and Nintendo Research & Development 1.
Nintendo’s second handheld game console, the GameBoy, combines features from both the NES home system and Game & Watch hardware. The console features a dot-matrix screen with adjustable contrast dial. Five game control buttons (a directional pad, two game buttons, and “START” and “SELECT”), a single speaker with adjustable volume dial, and, like its rivals, uses cartridges as physical media for games. The color scheme is made from two tones of grey with accents of black, blue, and dark magenta. All the corners of the portrait-oriented rectangular unit are softly rounded, except for the bottom right, which is curved. At launch, it was sold either as a standalone unit, or bundled with one of several games, among them Super Mario Land and Tetris. Several accessories were also developed, including a carrying pouch, a camera, and a printer.
