Beyond that, if you move Star, you have to move around another set of call letters. Not that it's rocket science to do that, but out-of-town agency buyers reading ratings are looking at call letters (there's no frequency listed). So if their Pittsburgh buys always included WZPT then you don't want to make them figure out that they now need to buy WBZW to get those 25-54's they used to get on WZPT.
That's also why they "have the call letters of 2 formats ago." These buyers a lot of times are young and impatient.
Well said. It's funny how broadcasters are now finally realizing the ramifications of the call letter shell game. I always found it highly amusing how stations changed their call letters and then buried them in their ID and adopted a brand instead. During the Mix Jamz era:..."WMXP, New Kensington/Pittsburgh", buried in the :50 break between spots. 2 seconds tops. Why even bother?
Yet WLTJ still brands as "Q92.9". :-\
