Probably not. Especially since there will be money to be made with the web based targeted ads. It seems a lot of telecommunication companies have signed on for it.Will FCC eventually sell all the bandwidth? They are like a junkie selling home furniture.
I'm in the Detroit market, they wouldn't have spent a ton of money to upgrade their transmissions for nothing (ATSC 3.0).
I think free TV is safe until they wire all the rural areas with broadband.
