I opened my iHeart app today and one of the icons was for WNAM - America's Best Music. So I clicked it.
I got several commercials for things like Charmin tissue, clearly national spots. Then silence. Awww. iHeart hasn't taken down the WNAM icon, even if the station is now dark. The national spots run before you can hear the station. But with WNAM, there's nothing to play after the commercials are over.
Even in a large market like San Francisco, Cumulus doesn't think anything it could put on AM 560 would be worth keeping the station going. So it went dark in 2025, along with other Cumulus AM stations like 1070 in Birmingham and now 1280 in Wisconsin.
