What Is PlayStation and Which Console Generations Exist?
PlayStation is Sony's video game console brand, launched with the original PlayStation in 1994. That first machine is now usually called the PS1 (or PSX), and it began a line of generations that runs through the PS5. If you want to place a specific console, game, or term like "PSX" in context, the generations below are the main map.
PlayStation vs. PS1 vs. PSX
The naming trips people up because the same hardware has several labels:
- PlayStation — the brand name for all Sony consoles, and also the original 1994 console's official name.
- PS1 — the common retroactive name for that original console, used to separate it from later generations.
- PSX — originally a shorthand for "PlayStation" (from "PlayStation Experimental," the console's pre-release codename). It now often refers to the same original console and its game library, which is why retro sites advertise "PSX games."
So when a site says it hosts PS1 or PSX games, it generally means titles from the original PlayStation era.
The main console generations
| Generation | Console | Rough era | What defined it |
|---|---|---|---|
| 1st | PlayStation (PS1/PSX) | 1994 onward | Disc-based games, 3D graphics, huge third-party library |
| 2nd | PlayStation 2 (PS2) | 2000 onward | DVD playback, backward compatibility with PS1 discs, best-selling console |
| 3rd | PlayStation 3 (PS3) | 2006 onward | Blu-ray, online network, early models played PS1 and PS2 discs |
| 4th | PlayStation 4 (PS4) | 2013 onward | No disc-based backward compatibility; digital re-releases instead |
| 5th | PlayStation 5 (PS5) | 2020 onward | Plays most PS4 discs and downloads; PS1 titles mainly via digital catalog |
The key differences across generations are the media format, the graphics capability, and how far back each console can play older games.
Backward compatibility, by model
Backward compatibility is the ability of a newer console to run older games, and it is not consistent across the line:
- PS2 plays most original PlayStation discs.
- Early PS3 models play both PS1 and PS2 discs; later slim models dropped PS2 support.
- PS4 does not play PS1 or PS2 discs. Older titles return only as digital re-releases.
- PS5 plays most PS4 discs and downloads, but PS1-era games come through digital offerings rather than original discs.
Because support varies by model, check the specific console revision before assuming an old disc will work.
Where you can still play PS1 and PSX games
Original discs and hardware still work if you have them, but there are lighter options. Browser-based retro sites host PS1 and PSX libraries that run directly in a web page, with no console or disc required — for example, PS1FUN describes a large retro PlayStation 1 library playable in your browser, covering genres such as action, adventure, puzzle, RPG, and fighting. These collections are a practical way to revisit the PS1 era or try titles you never owned, though availability of individual games varies by site.
