When I was a kid, someone told me that Rivers programmed all of their stations with one of the "Three R's: Race, Religion and Rural."
Don't really go for religious or gospel programming, but I used to listen to WEAS all of the time when it was a country station back during the 1970's. One summer, they ran a program called "The Zero Hour," which was old-school radio drama done in the fashion of radio's hayday. I still remember those shows.
