The PlayStation Portable (officially abbreviated PSP)[4] is a handheld game console manufactured and marketed by Sony Computer Entertainment.[5] Development of the console was first announced during E3 2003,[6] and it was unveiled on May 11, 2004 at a Sony press conference before E3 2004.[7] The system was released in Japan on December 12, 2004,[8] in North America on March 24, 2005,[9] and in the PAL region on September 1, 2005.[10]
The PlayStation Portable is the first handheld video game console to use an optical disc format, Universal Media Disc (UMD), as its primary storage media.[11][12] Other distinguishing features of the console include its large viewing screen,[13] robust multi-media capabilities,[14] and connectivity with the PlayStation 3, other PSPs, and the Internet.[15][16]
Despite the console's superior computing power and its multimedia capabilities, sales have consistently lagged behind its main competitor, the Nintendo DS.[17] After the release of a remodeled, slimmer, and lighter version of the PlayStation Portable, appropriately titled Slim and Lite, in early September 2007, sales quadrupled in the United Kingdom the following week and increased by nearly 200% in North America for the month of October.[18][19]
