I would bet a cup of coffee that this morning show has a lot smaller payroll than TRG. If the ratings stay close to were they are now Cumulus has more positive cash flow off of 100.5. If the morning ratings tank, Cumulus simply goes the more music in the morning route like 97.1.
IMHO if Cumulus can get 100.5 to about a half of 97.1's 5.6 (6+) playing classic rock they should have some money demos to sell.
Could the station actually be billing pretty well all day long but the ratings (1.9 Nov) are simply not showing it?
