In 1990 Sega regained the U.S. rights to the [Master System](/museum/sega-master-system/) which they had sold early in the console's life to toy manufacturer Tonka. In an attempt to improve sales a smaller version of the Master System was launched. To cut production costs Sega removed the card slot which meant users could not play Sega Card games or use the 3D glasses. Also removed was the A/V output and the reset button, along with the Expansion port.

Despite the Master System II now being marketed by Sega, it was too late for the machine in America and the public simply weren't interested. As a result of poor sales, Sega decided to withdraw the Master System II from the American market in 1992. Support for the console continued in Europe until 1996, where it was eventually dropped to allow Sega to concentrate on the [Mega Drive](/museum/sega-mega-drive/)'s successor, the [Saturn](/museum/sega-saturn/).
