I believe the simple economic answer is that more TV stations would
dilute the advertising dollar and the stations wouldn't be viable.
It has always seemed to me to be a monopolist's argument (tri-
opolists? quintopolists?). That's the supposed answer to why we
only have 5 channels not why we don't use the unallocated channels
for something else.
