Same thing happening with TV; HD is going to be almost all subscription if not PPV. The new ITV HD channels are going to be exclusively on Sky satellite, where they can tap into the revenue stream. There's a degree of this going on already on the net: high bandwidth sites have to pay for faster content delivery over dedicated links. If they didn't they'd rapidly become unusable. The problem chiefly occurs at the consumer end where ISPs are effectively subsidising the process. The iPlayer trick is to offload the distribution onto other people using Bit Torrent technology. That begs the question of whether some of the licence fee should be redistributed to UK ISPs, as the Beeb is sidestepping its traditional role of transmitting its own material.
