Released August 1989 It was 1989. Nintendo's NES had reigned supreme in the video game market for nearly five years, and it was time for a new system to take over the throne. Sega's Master System, while graphically superior to the NES, failed to make any kind of lasting impression in the U.S. market (although it was very popular in Europe), and Sega knew that their next system would not only have to be superior to everything else out there, but they'd have to have a lot of third-party developers lined up.
After two years of development, Sega introduced their "next generation" system to the world in late 1989. Known as the Genesis in the West, and the Mega Drive in the east, Sega began an aggressive marketing campaign, not only to customers, but also to developers.
Although NEC's TurboGrafx-16 had beat the Genesis to market by nearly four months, Sega quickly regained lost ground, thanks to their line-up of quality arcade conversions, killer sports games, and most of all, the full support of Trip Hawkins and Electronic Arts.
