Eventually WINS and WCBS will have to both move to FM. You can't move one without the other. The one left exclusively on the AM dial would be doomed.
And it would make no sense for Audacy to doom two of its top billing stations in the chain, in order to keep WNYL and WXBK chugging along at the bottom of the ratings and revenues. I wish AM radio were still viable. But increasingly it's not.
A few AM-only stations are hanging on, enjoying high revenues and getting decent ratings. Someone mentioned WBZ, one of Boston's highest billing stations. Same with KFI Los Angeles and a few others. But man, that list is getting smaller. And the clock keeps ticking.
WINS and WCBS don't get the ratings they once did. Both were once solidly top 5 in the NYC ratings. But thanks to spoken word formats' ability to run more spots each hour than music stations, their billing is still among the tops in the Audacy chain, ahead of even well-rated FM stations like WNEW-FM and WCBS-FM. And CERTAINLY ahead of WNYL and WXBK.
So in the not-too-distant future, Audacy will have to do in NYC what it's done in LA, Chicago, SF and Philly. Give its all-news stations an FM simulcast.
