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.
Sega
Sega released the Master System's successor, the Mega Drive, in Japan on October 29, 1988, though the launch was overshadowed by Nintendo's release of "Super Mario Bros. 3" a week earlier. Positive coverage from magazines "Famitsu" and "Beep!" helped establish a following, but Sega only shipped 400,000 units in the first year. The Mega Drive could not overtake the venerable Famicom and remained a distant third in Japan behind Nintendo's Super Famicom and NEC's PC Engine throughout the 16-bit era. For the console's launch in North America, where the console was renamed Genesis, Sega had no North American sales and marketing organization. After Atari declined an offer to market the console in the region, Sega launched the console through its own Sega of America subsidiary. Genesis was launched in a limited number of markets on August 14, 1989, and in the rest of North America later that year. The European version of the Mega Drive was released in September 1990.
