Third that it makes no difference to advertisers whether I listen to a
networked program carrying regional and national commercials on AMBCB
on a station that is local or distant. I hear the commercial and can
respond to the 1-800-number or go to the web site and make a purchase
so the advertising does its job either way.

So when I respond to an advertisement who can know what station I heard
it on. Do they just make the assumption that it was a local station?


They can tell because frequently each station gets a commercial with a
different 800 number on it.

Those 800 number ads are seldom paid commercials. They are paid for based on
the number of calls, which is often zero... but they run in times where the
station has nothing salable so there is some gain. You will find them used
as filler in syndicated shows, which have commercial windows. The syndicator
puts these spots in, and if the station has no better spots (sold ones) they
run as fill. This is like the 800 adds on cable TV. If the local cable
system has paid ads, they superimpose them. Otherwise, they make a few cents
on the "100 Greatest Hymns" collection.
