PlayStation Portable (2004)
Upon its release, Sony’s portable was prematurely billed as the future of portable gaming. Great third-party support, high-caliber graphics, and a favorable control scheme that resembled the DualShock, the PSP seemed poised for greatness. That was far from the case. The introduction of a new media format known as UMD, short for Universal Media Disc, boasted serious drawbacks from fragility to longer loading times. Sony’s move to sell movies for the PSP backfired as well, as the discs cost just as much as DVDs and offered lower visual quality. Nintendo soon saw an increase in 3DS sales and sat comfortably on the handheld throne once again.
