All radio in its first three decades was "syndicated" and done in one of a few major cities and sent to stations across the nation. Almost all TV except for local news is done that way, too.Would you argue that remotely voice tracked segments or syndicated programs that have no connection to your city be considered live audio program service? I’ve heard voice tracked segments from people who have no local connection, they’re all pre recorded and not useful for the station because listeners notice the difference and make fun of the station. So radio can still have notoriety, but for all the wrong reasons.
The fact is that well done voice tracking can be as good as local live programs, and when a station uses top talent for nights, overnights, weekends and holidays it actually improves the overall station sound.
One of contemporary radio's biggest shows, American Top 40, was prerecorded in LA and sent to stations for later play. You can't tell me that listeners "made fun" of that... or of Larry King, Rush Limbaugh, Ryan Seacreast, Bobby Bones...
