Hannity has his own affiliates. He can't abandon them for another show. It's one or the other. Moving to noon means he had a five hour hole in his day before his TV show. Then what do his former affiliates do? It doesn't solve iHeart's problems. It creates a new one.
How does Hannity have his own affiliates, vs. Premiere's affiliates? Does Hannity sell his show himself to some stations? In any case, Premiere has a problem to solve from noon-3p, and Hannity is the only one in the Premiere stable with national appeal, with the possible exception of Glenn Beck.
I do agree that replacing Rush with Hannity opens up another hole. That hole has plenty of incumbent players but nobody of Rush's scale. But Rush's scale took time--it took Hannity time to go from being local on WGST opposite Boortz 9a-noon to where he is today. 3-6p seems like a harder hole to fill with syndicated content because of the need for more news, traffic, etc. for PM drive. Think of all of the PM drive local talkers that talk a lot less than a syndicated show (Erickson, Kimmer, et al.)
Unless you think talk radio is dying already, and we're going to have a shakeout and then there will be more talent than outlets to carry them.
How many Hannity affiliates carry his show live? Obviously WSB doesn't care that much about Hannity if they are willing to hack up his show like they do. Unless it's an attempt to start Erickson's, and now Arum's, show later to get a greater share of PM drive and they just need an hour of filler to keep people from tuning away.
I'd like to see how many Erickson listeners like Hannity, to see if an hour of Hannity will keep WSB listeners tuned in 3-4p. I am guessing that more Rush listeners like Hannity than Erickson's listeners do, since Rush and Hannity evolved to the same style and POV and Erickson is quite different.
