If any of you think that just because of Rush WPTF and WSJS have been successful over the years, then you just don't know much about radio. It is a total package. Yes, Limbaugh can be a centerpiece, but if you examine ratings of both stations through the last 15 years, you will find they had other strong elements that contributed to the overall success (ratings & dollars).
Both stations had strong, long running morning shows (at least up until four years ago). And with no disrespect to Brian Freeman (who has been on both), the Morning News programs just didn't have the highly local appeal the previous shows had.
The transition to "pay to play" radio has been detrimental to both (particularly to WSJS). It has been a long, slippery slope that began ten years ago. The amount of money a "guest expert" spent with the station over the course of a year was more important than the content they shared with the listeners. Guest slots were "sold" to people who had little mass appeal, and didn't really grasp the idea of "give the listener something he can use for free, and when it comes times for him to spend money, he will spend it with you".
There are a few who got it - Mike Wells, The Hungerfords, Gib & John, David Dalrymple (when he did the handyman show), the early Computer Talk folks (Steve and Stephen, Deb & Gary). Most of the others were either too narrowly targeted (sales training, elder care, and other highly specialized fields) or always answered "you can call the office and we will set up an appointment" or "bring it by the store and we'll see what's wrong".
There is a BIG difference between Clark Howard and Dave Ramsey. Dave talks about nothing but being totally out of debt! Clark talks about travel, technology, dealing with customer service, and lots of things you can put to use daily. Ramsey has bought his way onto radio stations across the country.
Want to have a successful radio station? It is simple. Figure out what attracts listeners and sell them to advertisers. It is NOT a chicken or egg thing! The listener must come first, but seldom does.
