The Game Boy the 8-bit handheld game console developed and manufactured by Nintendo was the first handheld in the Game Boy family, first released in Japan on April 21, 1989, then North America, three months later, and lastly in Europe, over a year later.
It was designed by the same team that developed the Game & Watch and several Nintendo Entertainment System games. 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 an adjustable volume dial, and, like its rivals, uses cartridges as physical media for games. At launch, it was sold either as a standalone unit or bundled with one of several games, namely Super Mario Land or Tetris. Several accessories were also developed, including a carrying pouch and printer.
