"where they have the exact same 3 person radio show in every city"
On every station, not in every city. There is no radio alternative where I live other than morning zoo shows.
This is a typical indication of aggressive narrowcasting. "Our goal is to increase our percentage of morning zoo listeners by becoming a better morning zoo". Unfortunately the product that is the most popular among zoo listeners is likely abhorrent to the general population. They're going to chase each other all the way down until the few advertisers left won't be able to pay the electric bill, and right up to the bitter end they'll be trumpeting their "percent of total listeners" metrics rather than "total number of listeners" metrics. All I care about is having a bigger slice of the pie, and don't care how much smaller the whole pie gets.
