WBBM and KCBS are all news, no talk. The news/talk station in Chicago, WGN, dropped from first to third.
So, WGN rides the Randy Michaels merry-go-round and WBBM benefits. There's a shock. KCBS benefits from the Cumulus upheaval at KGO. I still don't see where AM is the problem here. Sounds more like good programming benefitted from bad moves by the competition, and that AM is still viable. The drops have nothing to do with what band they're on.
KYW, traditionally #1 in Philly, has seen a 2 point drop in the last two books. There's talk of the format moving to FM.
Let's clarify that. It's more like a 1.5 shares, over 3 winter months. That's not a drop, that's barely a wobble in the real world. I'm sure that CBS would love to have another FM in Philly, and everybody on AM talks about moving the format to FM so they can "get younger listeners." Well, the format is what gets younger listeners more than the band. WGR and WBEN in Buffalo prove that every book.
WSB is the only AM that gets better than a 2 share in Atlanta, and it's not a traditional conservative news talker. That distinction goes to WGST.
So, an AM looks very healthy in Atlanta. Maybe Cox simply puts out a better product than Clear Channel. Obviously, AM is viable if the programming is good enough. We can certainly see what Clear Channel has done to the programming at WHAM, and others. It certainly hasn't gotten better.
