A timeline of events that took place in 1991.
Console hardware releases
While Nintendo initially dominated the market with its' 8-bit Nintendo Entertainment System, released in 1985, Sega gained momentum when its' 16-bit Genesis machine hit the market in 1988. Facing loss of marketshare and an aging console, Nintendo reluctantly designed a new machine. Ten months after the Super Famicom was released in Japan, Nintendo replaced the Nintendo Entertainment System with the SNES in America. The system, which would go on to sell over 49 million units worldwide, included Super Mario World and retailed for US$199.
