While I was in it, working in radio was never ever squeaky clean (Carol Miller's book will attest to that).
There's a famous story about Carol when she was at WNEW-FM. She was hearing about the rise of grunge music in the west, so she called one of the other DJs in Seattle for some intel. She asked "Do people actually like this stuff?" And she was told they did. But WNEW never got into the grunge scene the way they had for punk and other similar rock. As a result, WNEW become old and out of touch, completely missed Nirvana and other big bands, and ultimately changed format to hot talk. Sometimes it helps to have an open mind.
