HD will continue flounder. I'm sure that CC did a complete HD package for all stations. Unless a translator can be strapped to a HD channel... it is a worthless moot point, and nobody cares. HD is around for that very reason. Local market managers probably have the authority to add what they like if a HD channel is available and not use. Me says there is a Jazz fan in the house.
With license fees topping 10K a year for HD. It will never be a reality for small and medium markets. I know one small group that is using it, but once again they have two translators.
The Mobile Pensacola market is in good shape for formats catered to the average listener. With the exception of Classic County (will never sell) Classic Hip Hop (numbers are starting to erode in markets) and Classic Hits (has failed over and over). Sunny does well as a small market station and doesn't have the pressure of numbers or ratings.
A classic R&B station might do well.
The market is over raydeeoed. and Mobile is not translator friendly (from a signal standpoint).
