Sega
In 1940, American businessmen Martin Bromley, Irving Bromberg, and James Humpert formed Standard Games in Honolulu, Hawaii, to provide coin-operated amusement machines to military bases. They saw that the increase in military personnel with the onset of World War II would create demand for entertainment at military bases. After the war, the founders sold Standard Games and established a new distributor, Service Games, named for the military focus. In 1951, the United States government outlawed slot machines in US territories, so in 1952 Bromley sent two employees, Richard Stewart and Ray LeMaire, to Tokyo to establish a new distributor. The company provided coin-operated slot machines to U.S. bases in Japan, and by 1953 had changed its name to Service Games of Japan. The name Sega, an abbreviation of Service Games, was first used in 1954 on the Diamond Star Machine, a slot machine.
