There was probably a glitch on the R.I. page such as not having all the numbers by deadline. According to All Access, WFYV earned a 3.4 share (6+) for the month of May. Still, there are a few inconsistencies. R.I. indicates Jax as market #49 while A.A. lists Jax as #50. One has the Rock 104-5's current format as "classic rock" and the other just"rock." I don't know what is correct, perhaps someone can clarify.
You're right, looks like a glitch (seems to happen a lot on R-I, AllAccess not so much) Looking at Rock 1045, I'm curious if or when they will make the switch to a "hot talk" type format like COX did in Tampa to The Bone or perhaps put WOKV on 104.5 giving them full market FM coverage. It all depends on revenue, so they have to weigh could they make MORE money with either one of those flips. I don't have access to current billing nor research so they may be doing just fine as is.
