First, my comparison was not about the content, it was that no one till more recently thought HBO would allow access without a Cable/Sat subscription just like some are trying to say Networks without locals can't or won't happen.
Second, the Networks ARE a national feed no different than TNT, AMC with their own programming. NBC could go to Cable only by dropping all affiliates, with it's shows nationwide and to use your example with any movies they have rights to, just like TBS. In fact in Boston NBC is toying with almost exactly that, dropping the affiliate and providing NBC programming themselves, but taking the extra step of it not being OTA.
When the locals are showing something from NBC they are simply an extension of the Network with an agreement to show Network programming. When not showing NBC (or whatever network) programming they are on their own for local news, syndicated programming etc.
Third, right now I can watch CBS online, LIVE if I am in any of 101 markets already up from the original 14, and next day anywhere for $5.99 a month. That doesn't sound like it is approaching the HBO model?? The CBS approach for online includes it's affiliates on the revenue side and they set it up to allow anyone to get CBS online live if they are in a market that allows it, not just if they
live in a market that allows it lending even more credence that the Network programming is indeed or can be National. (I can travel and still watch live, their form of out of market)

Further remember, the FCC is looking to change the exclusivity law. There is nothing in media transmissions that can't be changed if the parties involved think they have a better chance succeeding by doing so. Citing laws means little when change is wanted by the parties involved
or the Government.
Which brings us back to the possibility of DISH being able to import another local during a dispute if the Government wants to allow it. I'm not saying this going to happen overnight, or exactly how the change will take place but it is obvious there is going to be a changes to the Network/Affiliate structure some that have already taken place, some coming.
Doesn't the fact that I can pay $5.99 and bypass a CBS local affiliate dispute still watching live all orchestrated by CBS say something?
