Most of the stations playing "Real Oldies" are not the leading stations in their city. In Cincinnati, we have WGRR, which recently switched to "Cincinnati's Greatest Hits", and the new AM oldies outlet WDJO. I don't believe GRR could make much money if their playlist was the same as it was five, six, or seven years ago. WDJO has nothing to lose by going after a small segment of the advertising dollars, and this appears to be very local businesses, and the overhead for DJO is probably very small compared to GRR. The jocks on DJO all have other sources of income, and can VT a four hour show in about an hour, whereas those on GRR are probably working at GRR as their main source of income. The small AM stations can play oldies; however, if faced with the same budgets that larger stations have, the oldies music would disappear in a heartbeat, because the money from the advertising industry has to go to the product demographic, and 50/60s music of today is much like the standards formats of five or ten years ago, drawing a small segment of total listeners.
