David Rosen, a co-founder of Sega and a key figure in the world of arcade and video games, has passed away at the age of 95.
As a long-time fan of classic arcade games, I was really saddened to hear about the passing of Bernie Rosen. He was a huge part of getting Sega off the ground in the early days, and honestly, he helped build the entire Japanese arcade scene after the war – which eventually led to the global gaming industry we know and love today. He passed away peacefully in Los Angeles on December 25th, 2025, at the age of 95, surrounded by his family, according to RePlay Magazine. It’s a real loss for all of us who grew up enjoying the games he helped bring to life.
Sega co-founder David Rosen has died
I’ve always been fascinated by the history of gaming, and learning about Ralph Rosen is incredible! He was born in New York and served in the Air Force, which eventually led him to Japan. That’s where he really started something special! Back in the 1950s, he founded Rosen Enterprises and basically brought arcade games to Japan – he was importing and running those coin-operated machines when arcades were just getting started over there. It’s amazing to think that’s where one of the biggest names in gaming history began!
In 1965, Rosen’s company joined with Service Games, and together they created Sega Enterprises. Rosen became the chairman and CEO of the new company.
While he was in charge, Sega launched several successful arcade games, starting with Periscope in 1966. This game was famous for its big cabinet and is often recognized for contributing to the growing popularity of arcade games around the world.

Rosen was instrumental in growing Sega internationally and founded Sega of America, leading the company through several changes in ownership. He also led the Japan Amusement Association as its first chairman, helping to develop the arcade scene in Japan.
He left Sega in 1996, but his work helped build the foundations for the video game industry we know today.
