Apple Pressuring TV Networks to Halve iTunes Episode Pricing?
The plan is seen as an integral part of the iPhone maker's strategy for the tablet computer, which it is expected to unveil tomorrow.
However, networks are resisting the move as they fear a repeat of the music industry's pact with Apple in 2003 to sell individual songs for 99 cents on iTunes. The price helped to simplify and boost downloads of digital music but dented album sales .
Apple has also been rumored to be developing a monthly subscription service for a "best of television" package that would offer consumers a variety of content from the networks in what Apple hopes to position as a replacement for traditional cable TV subscriptions.
