The SG-1000 is a cartridge-based home video game console manufactured by Sega. Introduced in 1983, it was developed in response to a downturn in arcades in 1982. Its game library comprises 68 standard cartridge releases and 29 Sega Card releases. The SG-1000 made little impact in the video game industry, but provided the basis for the more successful Master System in 1985.
