I don't know how much domestic SW could compete with domestic clear
channels. Radio did, and does, depend on advertising. And most radio
advertising is local. Sure, the clear channel stations had a
nighttime
coverage of hundreds of miles, but did they do much of their own
programming
for people outside their prime coverage area? I'm guessing they
didn't.
If
they did, would it have increased their advertising revenue?

In the 30's, when the non-domestic prohibition was written, a huge
portion
radio advertising was national network. It was, in fact, hard to be an
independent station outside of a couple of the very largest markets
until
Top 40 developed in the early 50's.

The term "disc jockey" (shortened to DJ) wasn't even coined until 1950,
when stations were losing their programming to television and had to
play music nonstop to fill time. (Alan Freed was NOT the first DJ, only
the first to be famous.)

Actually, I have found references to the term in late 40's Broadcasting
Magazines. I believe the term originated just after the ASCAP decision when
radio stations could play lots more recorded music.
