Broadcast television in an IP world

Why would an ISP not want to conserve edge resources? If I’m doing iptv I’m better off doing multicast which would conserve loads of BW for something popular like the Super Bowl. Especially if I’m doing this over docsis.

It is merely that third parties should pay ISPs offering multicast
service for them. Amount of payment should be proportional to
bandwidth used and area covered.

Since multicast benefits the ISP the most, why should the ISP charge the
content provider for multicast?

The content provider (lets say local TV station that broadcasts the
Superbowl) can just unicast to the ISP a single stream, and give the
ISPs some pizza sized box (lets call it an "Appliance") and that box
then provides unicast delivery to each customer watching the Superbowl.

The ISP only wins in reduced transit/peering load, but not on the load
on its distribution network.

And with the switch to on-demand programming, one wonders if the cost of
setting up multicast all the way from the "border" to every bit of CPE
equipment is worth it if it is only truly beneficial for the Superbowl
and a couple of Hollywood awards ceremonies per year.
