Not at noon. MOST people are at work. Those who don't work are interested in personal finance. Ramsey does talk radio the way it was done in the 60s and 70s, and the news/talk demo obviously loves it. If the station replaced him, there would be protests and complaints.
I highly doubt that KTAR listeners will be "protesting" if Dave Ramsey was relegated to a later time slot or left KTAR NEWS entirely. As long as there was a local outlet or station that broadcast his show, his "loyal listeners" will be sure to follow. I have a feeling that the vast majority of KTAR NEWS listeners that tune in from 5:00 A.M. to 12:15 P.M. and then from 2:00 P.M. to 8:00 P.M. are listening for the news aspect of the station, staying up to date on current events / breaking news and the talk elements of the news shows airing during that time slot. Those listeners are NOT sticking around to listen to the pseudo-infomercial that is the Dave Ramsey show that has ZERO news or even a news/talk element about it. That's my problem with the Dave Ramsey show on KTAR, it doesn't fit with the rest of the lineup and distracts from the live and local news nature of the station's format as he is neither live nor local nor news in any way.
