The Super Nintendo Entertainment System (officially abbreviated the Super NES[b] or SNES[c], and commonly shortened to Super Nintendo[d]) is a 16-bit home video game console developed by Nintendo that was released in 1990 in Japan and South Korea, 1991 in North America, 1992 in Europe and Australasia (Oceania), and 1993 in South America. In Japan, the system is called the Super Famicom (Japanese: スーパーファミコン, Hepburn: Sūpā Famikon?, officially adopting the abbreviated name of its predecessor, the Family Computer), or SFC for short. In South Korea, it is known as the Super Comboy (슈퍼 컴보이 Syupeo Keomboi) and was distributed by Hyundai Electronics. Although each version is essentially the same, several forms of regional lockout prevent the different versions from being compatible with one another. It was released in Brazil on September 2, 1992, by Playtronic. 

To compete with the popular Family Computer in Japan, NEC Home Electronics launched the PC Engine in 1987, and Sega Enterprises followed suit with the Mega Drive in 1988. The two platforms were later launched in North America in 1989 as the TurboGrafx-16 and the Genesis respectively. Both systems were built on 16-bit architectures and offered improved graphics and sound over the 8-bit NES. However, it took several years for Sega's system to become successful. Nintendo executives were in no rush to design a new system, but they reconsidered when they began to see their dominance in the market slipping.
