How Many Video Game Console Generations Are There? The Standard 9-Generation Model

There is no single universally agreed number, due to overlapping timelines and manufacturer-specific cycles. However, a widely accepted framework defines nine generations:

2. 2nd (1977–1983): Atari 5200, ColecoVision.
3. 3rd (1983–1990): NES, Sega Master System.
4. 4th (1987–1993): 16-bit era: Sega Genesis, SNES, TurboGrafx-16.
5. 5th (1993–2000): 32-bit: Sega Saturn, PlayStation, Nintendo 64.
6. 6th (1998–2006): Dreamcast, PS2, GameCube, Xbox.
7. 7th (2005–2013): HD era: PS3, Xbox 360, Wii.
8. 8th (2013–2020): PS4, Xbox One, Nintendo Switch.
9. 9th (2020–Present): PS5, Xbox Series X/S, Switch (transitional).
