Sega ST-V arcade system board

Sega is a video game developer, publisher, and hardware development company headquartered in Tokyo, Japan, with multiple offices around the world. The company's involvement in the arcade game industry began as a distributor of games and jukeboxes in Japan, [1] [2] [3] but because Sega imported second-hand machines that required frequent maintenance, it began constructing replacement guns and flippers for its imported games. According to former Sega director Akira Nagai, this led to the company developing their own games. [4] Sega released Pong-Tron , its first video-based game, in 1973. [5] The company prospered from the arcade game boom of the late 1970s, with revenues climbing to over US$100 million by 1979. [6] Nagai has stated that Hang-On and Out Run helped to pull the arcade game market out of the 1983 downturn and created new genres of video games. [4]

Sega has developed and released additional arcade games that use technology other than their dedicated arcade system boards. The first arcade game manufactured by Sega was Periscope, an electromechanical game. This was followed by Missile in 1969. [97] Subsequent video-based games such as Pong-Tron (1973), Fonz (1976), and Monaco GP (1979) used discrete logic boards without a CPU. [98] Frogger (1981) utilized a system powered by two Z80 CPUs. [99] Some titles, such as Zaxxon (1982) were developed externally from Sega, a practice that was not uncommon at the time. [100]

History of Sega overview about the history of Sega, a Japanese video game company and subsidiary of [[Sega Sammy Holdings]]

The history of Sega, a Japanese multinational video game developer and publisher, has roots tracing back to Standard Games in 1940 and Service Games of Japan in the 1950s. The formation of the company known today as Sega is traced back to the founding of Nihon Goraku Bussan, which became known as Sega Enterprises, Ltd. following the acquisition of Rosen Enterprises in 1965. Originally an importer of coin-operated games to Japan and manufacturer of slot machines and jukeboxes, Sega began developing its own arcade games in 1966 with Periscope, which became a surprise success and led to more arcade machine development. In 1969, Gulf and Western Industries bought Sega, which continued its arcade game business through the 1970s.
