The Sega Genesis was the first of its generation to achieve notable market share in continental Europe and North America, where it competed against a wide range of platforms, including both dedicated gaming consoles and home computer systems. Two years later, Nintendo released the Super Nintendo Entertainment System, and the competition between the two would dominate the 16-bit era of video gaming. The console began production in Japan in 1988 and ended with the last new licensed game being released in 2002 in Brazil.

This console is a variant of the European Mega Drive and often mistaken for a Japanese Mega Drive as they are almost cosmetically identical.
