The Sega Master System (SMS) was originally released as the Sega Mark III in Japan. It was released after Nintendo's NES (Nintendo Entertainment System) and was never able to catch up to its level of success. The hardware was superior to that of the NES but the number of quality games on Nintendo's console far out numbered those on the Master System.
This console was followed by a smaller but mostly similar version, the Sega Master System II.
