Let me rise in (limited) defense of news/talk on FM. Don't get me wrong - I love music, and I regret the number of classical and jazz signals that have switched over to news/talk.
But...
The truth is NPR is now radio news, for all intents and purposes, at the local and regional level. In all but the biggest markets, commercial radio has abandoned local news, so if you want to know what's going on, and you want it from your radio, you're listening to NPR. NPR has built a very strong network of local stations across the country with lots of talented local reporters, and those reporters get a lot of training, including in areas formerly reserved for the local paper - deep dives into government records, investigative work - but now largely abandoned by newspapers.
Besides, you just learn more about more things. I keep CNN/Fox/MSNBC on in my office all day, five days a week, and they all concentrate on two or three stories, which they beat to death. At least with NPR news/talk, I stand a fighting chance of hearing other news. The world is a more interesting place than the cable newsers make it out to be.
As for the original question, dunno. As more and more "local" advertisers are bought up by big, out of town companies, and as retail collapses into Amazon versus everything else, the economics of running a local FM station get trickier. People are still making good money with FM stations, but like everything else in media these days it all feels fragile.
