Most radio listeners tend to forget news-talk AM's as a whole...until someone blows up a skyscraper or shoots a prominent official or it's election season. Every time a big, newsworthy event happens, listenership on WBT, WSJS and WPTF will trend up for about two months.
It's good that such stations CAN build an audience, but such stations have to find ways to sustain that listenership when local, national and world events are in a "slow and steady" mode. I would say that all three of these stations are still looking for the solution to that. While WBT's lineup tweaking may be a bit disconcerting to some, it is all a part of their ownership's attempt to do just that.
Nationally, the answer seems to be for such stations to add FM signals. To me, that's giving up the battle and surrendering to the folks who try to tell us that "...no one listens to AM anymore...", which we know from data measured during crisis times to not be the case. However, the bottom line is making money...so it may come to that if news-talk is to continue to flourish in North Carolina's radio markets.
