Sega traces its roots to coin-op amusements serving U.S. military bases and postwar Japan. In the 1940s, American entrepreneurs behind Standard Games and later Service Games supplied slot and amusement machines to bases across the Pacific, while in 1954 David Rosen founded Rosen Enterprises in Tokyo and soon began importing arcade machines. The two lineages converged in 1965, when Nihon Goraku Bussan (bearing the “SEGA” brand—short for Service Games) acquired Rosen Enterprises to form Sega Enterprises, Ltd., with Rosen as CEO. Sega quickly pivoted from distribution to creating its own electro-mechanical hits, notably Periscope (1966).
Sega’s arcade prowess led to home hardware. After early systems (SG-1000, Master System), the Mega Drive/Genesis (1988/1989) paired bold marketing and fast arcade-style design with a new mascot, Sonic the Hedgehog (1991), giving Sega a powerful foothold in North America and Europe. Contemporary reporting highlighted how Tom Kalinske’s aggressive U.S. strategy helped the Genesis challenge—and at times surpass—Nintendo in the West.
The 32-bit and 128-bit eras proved turbulent. Sega Saturn struggled outside Japan, and though Dreamcast (1998/1999) was innovative—online from day one—Sega ended Dreamcast production in early 2001 and shifted to a platform-agnostic, third-party software strategy.
A major corporate turn came with the October 1, 2004 creation of Sega Sammy Holdings, integrating Sega (video games/entertainment) with Sammy (pachislot & pachinko). Since then Sega has run a global publishing business spanning console, PC, mobile, and arcades.
Through selective acquisitions Sega broadened its portfolio: it brought Atlus (the Persona / Shin Megami Tensei studio) into the group via the 2013 purchase and subsequent reorganization of Index assets, and in 2023 acquired Rovio (Angry Birds) to strengthen mobile capabilities. In recent years Sega has both restructured parts of its European operations and announced new entries drawn from its legacy—Crazy Taxi, Jet Set Radio, Golden Axe, Shinobi, and Streets of Rage—signaling a strategy of reviving classic IP alongside Sonic, Like a Dragon/Yakuza, Total War, Football Manager and Persona.
