Sega was originally founded in 1940 as Standard Games (later Service Games) in Honolulu, Hawaii, by Martin 
Bromely, Irving Bromberg, and James Humpert to provide coin-operated amusements for American servicemen on military bases. Bromely suggested that the company move to Tokyo, Japan in 1951 and in May 1952 "SErvice GAmes of Japan" was registered. Rosen Enterprises and Service Games merged in 1965 to make Sega Enterprises. Within a year, the new company released a submarine-simulator game called Periscope that became a smash-hit worldwide. In 1986, Sega of America was established to take advantage of the resurgent video game market in the United States. Sega would also release the Sega Master System and the first Alex Kidd game, who would be SEGA's mascot until 1991 when Sonic the Hedgehog took over.
