[BC] Network audio distribution

[Sid Schweiger]

 >>didn't NBC feed its eastern stations in a "round robin" manner as far
back as the late-30s? It was that way in the 40s. This was a loop that
went from NYC, perhaps to Boston, then through Cleveland, Chicago, ST
Louis, etc., the south, Washington and back to NYC.  Major points could
break the loop and insert audio. NYC, Chicago and Washington were
certainly origination points which could break the round-robin loop.<<

ABC Radio was set up that way until they went onto the bird in the
1970s.  If the engineer in New York put the audio from Washington in
cue, they'd hear the New York-originated programming delayed by about
3-4 seconds.  At that point only NY, Chicago and Washington could break
the loop to originate programming.  The main trunk from Chicago to LA
was reversible for left-coast originations.
