Yeah but the shows that the urban stations are running and producing are all bought by the rural stations. So the whole ecosystem needs the rural stations to help fund the productions.

The urban stations raise a lot of money locally (through pledge drives, and by hitting up local companies for underwriting, which is basically advertising). The rural stations don't, too few people. The rural stations get CPB money, and some of that goes back to fund shows that they carry, but mostly it's the cost to operate the stations. The urban stations aren't being propped up by the rural stations, there's too little money, even including the money that they get from CPB.
