Broadcast television in an IP world

It's not helpful for saving resources in DOCSIS (nor any other) edge
networks.  The economics mean that, as bits get sold in the US and many
other places, it won't be in the foreseeable future.  Customers care about
popular video sources.  Popular content sources have CDNs with local nodes
and/or direct (low cost) connections to their CDN.  That's far more
efficient than allowing multicast across WAN links.
