In 1940, Martin Bromley, his father Irving Bromberg, and a fellow shipyard worker named James Humpert formed a company in Honolulu, Hawaii also named Standard Games. In 1945, the company was sold and the three founded the company that would give Sega its name, Service Games.
In 1952, Service Games of Japan was set up to import coin-operated games for use by service members stationed in Japan.
In 1954, an officer in the United States Air Force stationed in Japan, David Rosen, set up a company that also imported games to Japan named Rosen Enterprises.
June 3, 1960 is the date which Sega considers its founding. On that date, distribution and manufacturing companies were set up named Japan Entertainment Products and Japan Machinery Manufacturing.
In 1965, Service Games merged with Rosen Enterprises and became Sega Enterprises as a portmanteau of Service Games.
Sega develops video games and also developed home video game systems until 2002. It has released several consoles, computers, and retro consoles that play pre-loaded games from its past systems.
