From Brooklyn to Tokyo: Rosen’s Early Years

Born in Brooklyn, New York, on January 22, 1930, Rosen’s journey began far from gaming. He served in the U.S. Air Force from 1948 to 1952, stationed in Japan during the Korean War. Drawn to Japan’s post-war resurgence, he remained and sought business opportunities.

Rosen founded Rosen Enterprises in 1954, initially selling Japanese art to the U.S. He also ran photo studios under the Photorama name. He observed the growing need for entertainment in post-war Japan. By 1957, his company imported and operated coin-operated amusement machines. These machines captured the attention of a large Japanese audience.

The Birth of Sega: A Merger and a Vision

A key moment occurred in 1965 when Rosen Enterprises merged with Nihon Goraku Bussan Ltd. The new company took the name Sega, short for Service Games. Rosen became its chairman and CEO. Under his leadership, Sega shifted from importing to manufacturing arcade games. Sega quickly rose to prominence in the gaming industry.

Sega gained recognition for innovation through titles like Periscope and Monaco GP. Rosen’s business skills and talent for spotting potential proved crucial. Throughout the 1970s and 80s, Sega expanded its arcade game collection. This helped transform arcades into mainstream entertainment destinations. As video games evolved, Rosen guided Sega into new markets.

Challenging Nintendo: The Console Wars

Sega entered the home console market in the early 1980s, directly competing with Nintendo. Sega’s initial system struggled, but the company persevered. Rosen, along with Hayao Nakayama, led Sega to launch the Master System. More importantly, they launched the Mega Drive (Genesis in North America).

The Genesis’ aggressive marketing, using the slogan “Genesis does what Nintendon’t,” resonated with older players. Sega Co-Founder David Rosen Dies at Age 95.
