David Rosen, the American co-founder of Sega, has died at age 95 on Christmas Day at his home in the Hollywood Hills district of Los Angeles, according to RePlay magazine.
Rosen’s journey began after serving as a United States Air Force pilot following the Korean War. He remained in Japan, founding Rosen Enterprises and later shifting into importing coin-operated amusements, including photo booths and pinball machines. In collaboration with Nihon Goraku Bussan, whose coin-op business Service Games would become Sega, he helped mark the birth of a venture that would grow into a global brand.
Arcade operations under Rosen laid the groundwork for Sega’s early success, and after returning to the United States in the 1980s he turned attention to home consoles. The Master System launched in 1986 and found traction especially in Europe and South America. The company then pursued its edgier identity with the Mega Drive, renamed Genesis for the US market, launching at the end of the 1980s (1988 in Japan, 1989 in the US, 1990 in Europe) and cementing Sega as a household name. The strategy leaned toward mature, action-oriented titles such as Golden Axe and Shinobi, which contrasted with Nintendo’s more family-friendly lineup.
Rosen remained with Sega through the mid-1990s, serving as chairman of Sega of America and as a director of Sega Japan until his resignation in 1996. He departed two years before Sega’s Dreamcast would arrive, a hardware effort that ultimately failed to sustain the company’s hardware division and prompted Sega to refocus on software.
Industry observers describe Rosen as a crucial bridge between coin-operated engineering and consumer electronics. In a 1996 interview, he emphasized Sega’s engineering and technological capability born from the coin-op business and noted that the same know-how could be translated into consumer products.
David Rosen’s passing marks the end of an era in which arcades and early home consoles converged into a single global company. His work laid the groundwork for Sega’s global footprint and shaped how the industry views the relationship between coin-operated amusements and home gaming.
