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.

Sega released its next console, the Sega Genesis (known as the Mega Drive outside North America), in 1988. Although it was a distant third in Japan, the Genesis found major success after the release of "Sonic the Hedgehog" in 1991 and briefly outsold its main competitor, the Super Nintendo Entertainment System, in the U.S. However, later in the decade, Sega suffered commercial failures such as the 32X, Sega Saturn, and Dreamcast consoles. In 2001, Sega stopped manufacturing consoles to become a third-party developer and publisher, and was acquired by Sammy Corporation in 2004. In the years since the acquisition, Sega has been more profitable, but has been criticized for prioritizing quantity of game releases over quality.
