How long should you give format to find it's leg's? I ask this because there is a radio group in Australia that doesn't seem to stick at things too long. Their CHR stations are travelling quite well, but the (so called) rock stations seem to be being "ajusted" every year or so. The management seems to not know where to focus their energy. I tunned in the other day to find that they had gone back to a format they had 2 years ago, before a very poor sounding "JACK like" format of most recent times.
