Look for this sort of thing to continue happening more and more.
Radio stations are losing money hand over fist. They can no longer "afford" to keep creative and talented people on their payroll. This results in a "cluster mentality" which basically creates a "cookie cutter" style of template for all stations managed by the large radio owner/operators.
This is what happens when business gets bad and too many high-priced executives who don't do the daily work of actually keeping the station on the air are taking home all the earnings. As long as you have this kind of thinking in corporate america, then you will see more of the "one size fits all" thing happening. This will be true in all industries, but we tend to notice it more in industries like radio, where creativity and individuality is fast becoming a thing of the past.
It's very sad.
