ECMA International has accepted Sony's Universal Media Disc (UMD), which debuted earlier this year in the PlayStation Portable (PSP), as an international standard. The UMD, which has a storage capacity of 1.8GB and resembles a small DVD enclosed in a plastic case, is currently used by Sony to store PSP video games and movies. However, now that UMD has been accepted as a standard, we'll likely see the format move to other devices, including PCs, which could open up a new market for UMD-based media for PSPs. Currently, a wide range of movie companies support UMD, as well--certainly more than I had expected--but this week's news could lead to even more UMD-based movie releases in the future
