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.

In 1990, Sega launched the Game Gear, a handheld console, to compete against Nintendo's Game Boy. The console was designed as a portable version of the Master System, and featured more powerful systems than the Game Boy, including a full-color screen, in contrast to the monochrome Game Boy screen. However, due to its short battery life, lack of original games, and weak support from Sega, the Game Gear did not surpass the Game Boy, selling approximately 11 million units. Sega launched the Mega-CD in Japan on December 1, 1991, initially retailing at JP¥49,800. In North America, it was renamed the Sega CD and launched on October 15, 1992, with a retail price of US$299. It was released in Europe as the Mega-CD in 1993. The add-on greatly expanded the potential size of Genesis games and upgraded the graphics and sound capabilities with a second, faster processor, vastly expanded system memory, a graphics chip that performed scaling and rotation similar to Sega's arcade games, and an additional sound chip. The Mega-CD sold only 100,000 units during its first year in Japan, falling well below expectations. However, Sega had success with arcade games; in 1992 and 1993, the new Sega Model 1 arcade system board showcased Sega AM2's "Virtua Racing" and "Virtua Fighter" (the first 3D fighting game), which played a crucial role in popularizing 3D polygonal graphics.
