🦔 Sega Sammy Holdings
Quick Summary
Sega Sammy is the parent company of Sega — once Nintendo’s fiercest console rival, now a third-party publisher and developer known for Sonic, Yakuza/Like a Dragon, Persona (via Atlus), and Total War.

From Console Rival to Developer
- 1983–2001: Sega operated its own consoles (SG-1000, Master System, Mega Drive/Genesis, Saturn, Dreamcast) — directly competing with Nintendo.
- 2001: Sega exited the hardware business after the Dreamcast’s commercial failure, becoming a third-party developer/publisher.
- This transition is one of gaming history’s most significant pivots.
