The PlayStation is a video game console of the 32/64-bit era, first produced by Sony Computer Entertainment in the mid-1990s. Later Sony produced the PSOne (a smaller version of the original).
The PlayStation was launched in Japan on December 3, 1994, the USA on September 9, 1995 and Europe on September 29, 1995. Having lasted over 11 years, the PlayStation has enjoyed one of the longest production runs in the videogame industry. On March 23, 2006, Sony announced the end of production.
The PSone (also PSOne, PS one, or PS1), launched in 2000, is Sony's smaller (and redesigned) version of its PlayStation video game console. The PSone is about one-third smaller than the original PlayStation (38mm � 193 mm � 144 mm versus 45 mm � 260 mm � 185 mm). It was released in September 2000, and went on to outsell all other consoles�including Sony's own brand-new PlayStation 2�throughout the remainder of the year. Sony also released a small LCD screen and an adaptor to power the unit for use in cars. The PSone is fully compatible with all PlayStation software. The PlayStation is now officially abbreviated as the "PS1" or "PSone," although many people still abbreviate it "PS" or "PSX". There were three differences between the "PSone" and the original, the first one being cosmetic change to the console, the second one was the home menu's Graphical User Interface, and the third being added protection against the mod-chip by changing the internal layout and making previous-generation mod-chip devices unusable. The PSOne also lacks the original PlayStation's serial port, which allowed multiple consoles to be hooked up for multi-TV multiplayer. The serial port could also be used for an external mod-chip, which may have been why it was removed, although size-constraints may also be to blame.
