In my view, very small. Apple think the future for media consumption is streaming. Not buying physical media, not receiving it solely via broadcasts that the provider dictates the schedule for, not requiring different broadcast equipment and technologies that are not standardised across all markets. In an on demand world, you don't need to timeshift anything. We're a way off that yet, but it we're headed that way already with the multitude of catch up services and live feeds available via the Internet.
