Check out Sony’s PlayStation hardware history from the PS Experience

It’s time for some nostalgia.

The PlayStation brand is 20 years old, and Sony is holding a big bash in Las Vegas to celebrate its gaming division. The festivities include a massive show floor with dozens of booths for big releases, indie games, and more. One of the coolest parts is a glass-case exhibit that contains all of the PlayStation consoles from the last 20 years, ranging from the original PlayStation to the PlayStation 4 20th Anniversary Edition system.
