All SEGA Consoles Ever Released (1983-2024)

Sega released over a dozen home and handheld consoles from 1983 to 2001, starting with the SG-1000 and ending with the Dreamcast, experiencing both massive commercial hits and significant failures along the way.
The Genesis/Mega Drive became Sega's biggest success, selling 40 million units and competing head-to-head with Nintendo during the 16-bit console wars of the late 1980s and 1990s.
The Saturn and earlier add-on peripherals like the 32X damaged Sega's reputation, while the Dreamcast arrived too late to survive the arrival of PlayStation 2, Xbox, and GameCube.

This is a complete history of every Sega video game console released over four decades. It covers the company's early attempts to break into home gaming, their golden era competing with Nintendo, and their eventual exit from the hardware market. Understanding Sega's console lineup shows how a company can dominate one generation, make strategic mistakes, and ultimately lose the console wars.
