Sega‘s international branches, Sega of America and Sega Europe, are headquartered in Irvine, California and London, respectively.
Sega was founded by American businessmen Martin Bromley and Richard Stewart as Nihon Goraku Bussan on June 3, 1960. Shortly after, the company acquired the assets of its predecessor, Service Games of Japan. In 1965, it became known as Sega Enterprises, Ltd., after acquiring Rosen Enterprises, an importer of coin-operated games.
In 1982, Sega released SubRoc-3D, a first-person arcade shooter game. It is the first commercial video game in stereoscopic 3-D, using a periscope-shaped display with a different image for each eye. It was jointly developed by Sega and Matsushita Electric (now Panasonic), who developed its active shutter 3D system. The game has stereo sound and also changes the backdrop to reflect day, night, dawn, and dusk.
The game was a commercial success for Sega in arcades. The stereoscopic 3D effect is achieved with an active shutter 3D system. It uses a special eyepiece, a viewer with spinning discs to alternate left and right images to the player’s eyes from a single monitor. The player’s face is pressed against the eyepiece, which is shaped like a submarine periscope and attached to a controller below.
