What is the name of the first PlayStation handheld console?

The first PlayStation handheld console was the PlayStation Portable, commonly abbreviated PSP.

Sony released the PSP in Japan on December 12, 2004, making it the first handheld installment in the PlayStation console family. It then launched in North America in March 2005 and in PAL regions in September 2005. The system entered the seventh-generation handheld market as a technically ambitious rival to Nintendo’s DS.

One of the PSP’s defining features was its Universal Media Disc, or UMD. Games and films were distributed on the small optical discs, making the PSP unusual among handheld systems. It also offered multimedia playback, Wi-Fi, USB connectivity, and a relatively large 4.3-inch widescreen display.

PlayStation Pocket is not the official name of a Sony handheld, although the similarly named PocketStation can cause confusion. PlayStation Go was a later digital-only PSP variant, while PlayStation Vita succeeded the PSP in 2011. The PSP line sold more than 80 million units over its lifetime.
