Game Boy

Game Boy and its successors sold 118 million units, a figure that ranks fourth all-time, 22 million behind the Switch. Despite a grayscale display and 12-hour battery life, it launched in 1989 at $89.99 and dominated color competitors like the Sega Game Gear by bundling Tetris, which alone shipped over 35 million copies. The platform's 1,200+ game library and 15-year run established Nintendo's portable legacy, with the Game Boy Advance later extending that dominance.
