Mega Drive (Mk 2)
The Sega Mega Drive, known as the Genesis in North America, is a 16-bit home video game console developed and sold by Sega. The Mega Drive was Sega's third console and the successor to the Master System. Sega released it as the Mega Drive in Japan in 1988, followed by North America as the Genesis in 1989. In 1990, it was distributed as the Mega Drive by Virgin Mastertronic in Europe, Ozisoft in Australasia, and Tec Toy in Brazil.
Designed by an R&D team supervised by Hideki Sato and Masami Ishikawa, the Mega Drive was adapted from Sega's System 16 arcade board, centred on a Motorola 68000 processor as the CPU, a Zilog Z80 as a sound controller, and a video system supporting hardware sprites, tiles, and scrolling. It plays a library of more than 900 games created by Sega and a wide array of third-party publishers and delivered on ROM-based cartridges. Several add-ons were released, including a Power Base Converter to play Master System games. It was released in several different versions, some created by third parties. Sega created two network services to support the Mega Drive: Sega Meganet and Sega Channel.
30.75 million first-party Mega Drive units were sold worldwide. In addition, Tec Toy sold an estimated three million licensed variants in Brazil, Majesco projected it would sell 1.5 million licensed variants of the system in the United States, and much smaller numbers were sold by Samsung in South Korea. By the mid-2010s, licensed third-party Genesis rereleases were still being sold by AtGames in North America and Europe. Many games have been re-released in compilations or on online services such as the Nintendo Virtual Console, Xbox Live Arcade, PlayStation Network, and Steam. The Mega Drive was succeeded in 1994 by the Sega Saturn.
