Unhappy with the amount of revenue it receives by selling its TV shows through Apple's iTunes Music Store, NBC has decided not to renew its contract with Apple at the end of the year and to offer the programs via its own website instead, the New York Times reported today (Friday). NBC is the leading supplier of downloadable video on Apple's online store. In effect, the network wants to be able to determine how its programs should be priced and whether they should be offered as separate episodes or bundled -- possibly with movies from its corporate sibling, Universal Pictures. The NBC announcement comes just a day after the network said that it would begin testing a video download site called Hulu that it will operate jointly with Fox.
