Happy Birthday, PSP

The PlayStation Portable is celebrating its fifth birthday (in the US at least). Throughout its lifetime it has sold 17m units in the country.

The machine currently boasts a UMD games library in excess of 520 games, with an additional 300+ titles available to download on PSN.

In its time on the market it has undergone a number of revisions, including the ‘slim’ PSP-2000 model, though the PSP’s most notable reinvention was last year’s digital-only PSPgo, which shunned Sony’s UMD format in favour of PSN games distribution.

Today, the PSP system is a well-established handheld platform that continuously redefines portable entertainment with quality that’s unparalleled,” SCEA VP Peter Dille stated.

As PSP celebrates its fifth anniversary, the best is yet to come. We’re very excited about the vibrant 2010 lineup and are committed to continuing to offer entertainment experiences and immersive gameplay only possible on the PlayStation platform.”

PSP will celebrate its fifth birthday in Europe on September first. For reference, it was released in Japan in December 2004.
