In the late 60's (before satellite), I was working in Master Control Audio
at KYW-TV, Philadelphia when we were carrying a live NBC Network program.
There was a noticeable lip-sync audio delay.  It turned out that AT&T had
fed us the video directly down from New York but the audio was arriving
via the NBC Network "round-robin" microwave path which went from NYC to
Buffalo -> Cleveland -> Chicago -> St. Louis -> Nashville -> Atlanta ->
Washington -> Baltimore and lastly Philadelphia.  Being at the tail end
of the "round-robin" was often an interesting experience.
