The Japanese assets of Sega were purchased for million by a group of investors led by Rosen, Robert Deith, and Hayao Nakayama, a Japanese businessman who owned Esco Boueki (Esco Trading) an arcade game distribution company that had been acquired by Rosen in 1979.
Nakayama became the new CEO of Sega, Robert Deith chairman of the board, and Rosen became head of its subsidiary in the United States.
Sega prospered heavily from the arcade gaming boom of the late 1970s, with revenues climbing to over the industry's first stereoscopic 3D game, Sub Roc 3D, and the first laserdisc video game, Astron Belt. Carnival, Space Fury, Turbo, and Zaxxon were licensed to Coleco as launch titles for the Coleco Vision console in 1982.
Some of these and other titles were licensed to different companies for 8-bit computer versions.
In 1951, the government of the United States outlawed slot machines in US territories, so Bromley sent two of his employees, Richard Stewart and Ray Le Maire, to Tokyo, Japan, in 1952 to establish a new distributor.
Sega remains the world's most prolific arcade producer, with over 500 games in over 70 franchises on more than 20 different arcade system boards since 1981.
Sega is known for its multi-million selling game franchises, such as Sonic the Hedgehog, Virtua Fighter, Phantasy Star, Yakuza, and Total War.
Sega's North American division, Sega of America, is headquartered in Irvine, California, having moved from San Francisco in 2015.
Sega's European division, Sega Europe, is headquartered in London.
