The market is 40% Hispanic and African-American. Generally those listeners have zero interest in Classic Rock.
WHTQ may have done OK in-demo, but it was the lowest rated FMin the market with a full-coverage signal.
Clearly, if you want to know the "true" demo of your area, then look at the number of Spanish and other stations, regarless of what the stated Govt. figures are.
Radio always seems to be ahead of the curve, when it comes to the "real" demo of an area.
The 1996 Telecom Act is somewhat responsible for the lack good FM Rock stations. While the music is "good" there are just more bodies in the area, that like "other" music. And catering to the lowest common denom is what radio is really all about. Delivering quailty Rock music is the least of their concerns, no matter what there promos may state.
Destroying culture.... Big Business has got that down to an art !!!
