The Sega Master System was a console introduced by Sega in 1986, and was capable of 8-bit graphics. It was a rival to the very successful Nintendo Entertainment System (NES) but failed to match its sales in North America and Japan. However, it was successful in Brazil and Europe. Its life was long enough to see 4 Sonic games (5 in Brazil), before its discontinuation in 1991 in North America. In Brazil, it is still being produced.
