Only problem is the FCC does serve at least one purpose: stations (which admittedly pay license fees to be on the limited spectrum) might get a pirate station on or near that frequency, interfering with them, and the FCC shuts them down (or at least shuts down some of them). This affects radio more than TV. In one recent case in Boston, a pirate called Datz Hitz did Haitian music
one spot on the dial away from a legit classical station, causing them interference.
It also caused interference to Logan Airport aircraft radio.
They were shut down rather quick.
I believe there are several other important matters for them to oversee as well.
The question is, does there need to be an agency that does this, or could it be absorbed by another agency.
The next question is, can we severely restrict their power so that they don’t meddle in things they shouldn’t?
