I'll grant you this, though. Possibly with the much longer GI of DVB-T2,
a "proper" SFN up and down the East Coast would become more feasible. Of

affiliates.
I believe there is plenty of room for both. It would actually be easier to create local markets using SFNs because of the ability to better control the power and direction of the emissions. And there would be more channels available in each "market" since it would be possible to re-use channels more efficiently (less concern about high power levels reaching distant markets.
Every market could have the full complement of national networks AND some channels with local services. This is just a matter of determining local market boundaries and designing the network contours to accommodate this.
The big question is whether the national networks would still choose to use local affiliates? And then there is the question of how much localism could be supported economically if the networks were delivered as a national service?
