A direct competitor to the Nintendo Entertainment System, the Master System fought a long battle with Nintendo. Ultimately the system failed to beat the NES in the US and Japan. The system did, however, perform very well in Europe and Brazil. Sega’s system, in particular, is hugely popular in Brazil, even to the present day. Many Master System clones were produced by Tectoy in Brazil which have sold strongly across the decades.
Selling an estimated 13 million units, the Master System is estimated to have sold c. 13 million units. Comparing this to the 62 million NES units, it might be perceived as a failure, but for Sega, it was just the beginning of bigger things.
The Master System, in theory, is still available in regions such as Brazil, but the system typically stopped retailing in the mid-90s. The system was succeeded by the Sega Mega Drive/Genesis in 1988.
