>> KFI eased into more and more local product, so there is no reason why WABC could not strategically add some local content. <<
But that's a wrong comparison.
KFI being a CC station , their only commitment is to clear the Limbaugh show which is syndicated by Premiere CC, whereas WABC (Citadel) has to clear hannity, imus, levin, batchelor, McIntyre which leaves them with almost no room for any local show.
