The Game Boy is an 8-bit handheld game console developed and manufactured by Nintendo. The first handheld in the Game Boy family, it was first released in Japan on April 21, 1989, then North America, three months later.

Nintendo's second handheld game console, the Game Boy combines features from both the NES home system and Game & Watch hardware. The console features a dull green dot-matrix screen with adjustable contrast dial, five 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.
