Sega Genesis
30.75 million first-party Genesis 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 rereleased in compilations or on online services such as the Nintendo Virtual Console, Xbox Live Arcade, PlayStation Network, and Steam. The Genesis was succeeded in 1994 by the Sega Saturn.

Released in 1988, the Genesis (known as the Mega Drive in Europe, Japan and Australia) was Sega's entry into the fourth generation of video game consoles. In mid-1990, Sega CEO Hayao Nakayama hired Tom Kalinske as president and CEO of Sega of America. Kalinske developed a four-point plan for sales of the Genesis: lower the price of the console, create a U.S.-based team to develop games targeted at the American market, continue aggressive advertising campaigns, and sell "Sonic the Hedgehog" with the console. The Japanese board of directors initially disapproved of the plan, but all four points were approved by Nakayama, who told Kalinske, "I hired you to make the decisions for Europe and the Americas, so go ahead and do it." Magazines praised "Sonic" as one of the greatest games ever made, and Sega's console finally took off as customers who had been waiting for the Super Nintendo Entertainment System (SNES) decided to purchase a Genesis instead. However, the release of a CD-based add-on for the Genesis, the Sega CD (known as Mega-CD outside of North America), was commercially disappointing.
