Sega Genesis
Sega sold 30.75 million Genesis units worldwide. Of these, 3.58 million were sold in Japan, and sales in Europe and the U.S. are roughly estimated at 8 million and 18–18.5 million as of June 1997 (at which time Sega was no longer manufacturing the system) respectively. In 1998, Sega licensed the Genesis to Majesco Entertainment in North America so it could re-release the console. Majesco began reselling millions of formerly unsold cartridges at a budget price, together with 150,000 units of the second model of the Genesis. It released the Sega Genesis 3, projecting to sell 1.5 million units of the console by the end of 1998. An estimated 3 million Genesis units were sold by Tec Toy in Brazil.
Sega Genesis
Designed by an R&D team supervised by Hideki Sato and Masami Ishikawa, the hardware was adapted from Sega's System 16 arcade board, centered 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. The system 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. The Genesis has benefited from several add-ons, including a Power Base Converter to play Master System games, as well as multiple first and third party licensed variations of the console. Sega created two network services to support the Genesis: Sega Meganet and Sega Channel.
