The format was developed to enable recording, rewriting and playback of high-definition television (HDTV). Blu-ray makes it possible to record over 2 hours of HDTV, or more than 13 hours of SDTV on a 25GB disc. There are also plans for higher capacity discs that are expected to hold up to 50GB of data.
