The Sega Master System is a video game console by Sega. It was originally released in 1985 as the Sega Mark 3 in Japan. After being redesigned prior to its American launch, the console was renamed Master System and released in 1986 in America, 1987 in Europe, and 1989 in Brazil. Both the Mark 3 and the original Master System models could play with both cartridges and the credit card-sized Sega Cards, which retailed at lower prices than cartridges but had lower storage capacity.
