Like many other video game consoles, the PlayStation Portable is capable of photo, audio, and video playback in a variety of formats. However, unlike Sony's home consoles such as the PlayStation 3 and the PlayStation 4, it is not possible to play Blu-ray or DVD movies on the PlayStation Portable directly since it lacks a standard Blu-ray or DVD drive. While it does have a UMD drive and there exist UMD movies, the UMD format never saw implementation on any device other than the PlayStation Portable and as a result, the market is very limited compared to those for other optical media formats. There have been no more movies released on UMD since 2011, with Harry Potter and the Deathly Hallows – Part 2 being one of the final releases on the format.
