PSP( PlayStation Portable) was developed in the U.S. in 2005 by the Song Computer Entertainment Company. It soon became a highly desireble, portable and handheld wireless device for multiple entertainment purposes.
The PSP system allows users to view photos, listen to music, watch pre-recorded and live television, enjoy movies and backstage footage, access the Internet through a wireless connection, as well as the many free downloads available through the PlayStation website (wallpaper, movie trailers, screen shots, news & events).
As its name suggests, the PSP -- or PlayStation Portable -- is a smaller, lighter version of Sony's PlayStation. It's not as powerful as the PS2, but more powerful than the original PlayStation, and it has a built-in screen and speakers so you don't have to plug it in to anything to use it.
