The PlayStation Portable (also known as PSP) is a handheld game console made by Sony designed to rival Nintendo's highly successful Game Boy Advance and Nintendo DS. Released in December 12, 2004 in Japan and in 2005 in North America and the PAL Regions, it sold up to 80 million units. It is the only handheld console to use an optical disc format, called Universal Media Disc (UMD), as their primary storage medium. The Sonic Rivals series are exclusive to this handheld device. The PSP was discontinued in 2014. Its successor is the PlayStation Vita.
The PlayStation Store is an online virtual market available to users of Sony's PlayStation 3, PlayStation 4, PlayStation Vita (the PSP's successor), and the PSP game consoles via the PlayStation Network. The store offers a range of downloadable content both for purchase and available free of charge. Available content includes full games, add-on content, playable demos, themes and game and movie trailers. The PlayStation Store is planned to be unavailable to Europe, Oceania, Asia, and parts of Africa by September 15, 2014 though it will operate in the Americas.
