CHR is a format in decline. A large part of that is that there is no longer a "new hit single" by a hot artist that can only be heard on the CHR station. Now, an album is released, all of the tracks are immediately available on Spotify and the like, the Hot 100 is virtually meaningless, and Country is gaining in popularity because there is a growing perception that a lot of current pop is mediocre at best and pure dreck at worst.
Country, Classic Hits/Classic Rock, and Contemporary Christian are the formats showing growth now in terms of number of stations and listener levels.
Speaking of which ...
While agreeing with
@XCountry285, there is another factor to consider. The Florida panhandle is a bit more liberal than the rest of the state and Christian formats do better in conservative-leaning markets.
