The station owners are expanding and more Networks are being created. ThisTV, RetroTV, TuffTV etc...
Its likely that cable shows that cant command the prices that other do, will migrate somewhat to OTA. It is a win win situation for the station owners and those Networks. Or those networks could create new entities to air OTA...this gets around contractual agreements as well.
Its coming, dont worry.
However the Internet may kill everything.
