OK, so that's not the reason. We can rule that out. In that case, I stand by my main observation, which is that an oldies show is a break in format for a talk station. The only other major market station I know that has done this is WABC, and they stopped it several years ago. I know of no iHeart talk station that breaks format for a music show. I'm sure that's the main reason, because your other point is valid.
He's a good talent, he's done a good show, and maybe now he should pitch the idea to Entercom.
I thought the main premise of his show on 680 WRKO was to try to re-create the sound of "The Big 68" from the late 60s. On which Entercom station would this idea gain traction now?
