Sega’s roots stretch back to 1940 and a Honolulu-based company called Standard Games, formed by Martin Bromely, Irving Bromberg, and James Humpert. In 1951, Bromely inspired the company’s move to Tokyo, and Service Games of Japan (also known as Sega) was officially registered in May of 1952. Initially, Sega provided coin-op machines to U.S. military units stationed in Japan. The business branched out from there, supplying the domestic Japanese market as well as parts of Asia and Europe.

In 1965, Sega merged with another coin-op company, Rosen Enterprises, Inc. Formed by American entrepreneur David Rosen in 1954, Rosen Enterprises dealt in everything from instant photo booths to mechanical arcade games. A year after the merger, Sega released Periscope, a submarine simulator that became a worldwide hit.
