I'm amazed that this isn't everyone's most likely scenario. KNX needs an FM signal to meet its full potential in L.A. Upsides are the potentially better demos from being available to an audience that doesn't sample AM, and the fact that the expense of another full station is gone---they're already paying for KNX...they'd just need to simulcast it. And someday, KFI's gonna need to do that with one of its FM sisters, too.
I have a different opinion in that I think that all news and the current kind of talk are formats reaching the end of their useful life... like Beautiful Music in the late 70's and Smooth Jazz in the earlier years after Y2K.
As I just posted, during times of normalcy WBBM with an FM is not even in the top 15 in 25-54. To me, that indicates that, outside of Boomers, the format is vastly less relevant.
