They may be changing how they allocate funds, with less insistence in being all over the FM dial all over the country.
I have no insider information... just an analysis of the changes that the newer management has been making.
I have heard that Salem and other traditional religious stations that run national preachers, Focus on The Family, David Jeremiah, Chuck Swindoll, etc. are not getting the income from these shows that they once did. Fans of these shows can listen to them as a podcast. They don't need to tune in the Salem station at 4pm to get their daily dose of John MacArthur.
I've commented before that Family Radio has a big billboard on the Brooklyn-Queens Expressway. It advertises the radio network only using the web address. There's no mention of 92.7 FM. Even though it's licensed to Garden City, Long Island, WFME-FM has its tower on an apartment building in, yes, Queens. Is that an oversight on Family Radio's part? Or they just don't care much about their network of radio stations these days?
