Back in the early 70's when music formats began moving to FM, many national & local PDs went with the "more music, less talk" approach....really tightening the reins on any kind of "personality"....even if it was talk over the intro to every-other-song.
So, slowly, but surely, a whole generation (generations?) of listeners grew to hate ANYTHING that wasn't just the music.
We told them "more music, less talk", and today, outside of morning drive on music stations...radio might as well be totally voice-tracked with sweepers and spots. We inadvertedly trained the listeners to hate people on the radio. And, now most do.
We have only ourselves to blame. IMHO.
