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.
SG-1000
The SG-1000's launch did not prove to be successful. The three launch games, all of which were ported from Sega's VIC dual-arcade board, lacked the name recognition of Famicom launch games "Donkey Kong", "Donkey Kong Jr.", and "Popeye". Due in part to the SG-1000's steadier stream of releases (21 SG-1000 games by the end of 1983, as compared to only 9 Famicom games), and in part to a recall on Famicom units necessitated by a faulty circuit, the SG-1000 chalked up 160,000 units in sales in 1983, far exceeding Sega's projection of 50,000 units. Shortly after launch, Gulf and Western began to divest itself of its non-core businesses after the death of company founder Charles Bluhdorn, so Nakayama and former Sega CEO David Rosen arranged a management buyout of the Japanese subsidiary in 1984 with financial backing from CSK Corporation, a prominent Japanese software company. Nakayama was then installed as CEO of the new Sega Enterprises, Ltd. Following the buyout, Sega released another console, the SG-1000 II, on July 31, 1984 at JP¥15,000. The SG-1000 II has a different outer design from the original SG-1000, with the biggest difference being the replacement of the hardwired joystick with two detachable joypads that were connected through a pair of DE-9 ports on the back of the unit (the same controller ports that would later be used for the Master System and Genesis). Otherwise, it is functionally identical to the SG-1000 and is compatible with all the same software and peripherals.The lead designer of consumer hardware development at Sega, Hideki Sato, disliked the original cartridges, saying they looked like "small black tombstones" when inserted in the console, and later remarked that his proudest achievement of the SG-1000 era was replacing them with the "cheerier", pocket-sized Sega My Cards. Sega also employed popular owarai comedy duo Tunnels to provide celebrity endorsement for the console.
