I live in Australia, and I have been listening to K-ROQ the past few days via stream. I have noticed that KROQ may well be no more. The imaging is less K-ROQ and more K-R-O-Q. How long has this been happening? I can see why they did it, as the Alternative format is more pop these days.
I'm not a regular KROQ listener but I don't think this is anything new. Even during KROQ's Roq of the 80s heyday, the station was mostly referred to as K-R-O-Q. I think there was one drop in that said K-Rock. I will dig out some old airchecks to verify this.
