To bring back an old retort to that argument, I think a lot of the blame has to fall on the sales manager's and AEs' shoulders. The Oasis had the highly unusual selling point of being a station that crossed racial lines, and attracted the mid-to-upper echelon of each race (black and white.) The short time I was there, I became well aware that the black audience was being ignored. The target was apparently 35-54, but from what I saw at events and promotions, it attracted 25-64, both sexes, and heavier black than the intended white. It cut across many boundaries, and, as one could figure, most AE's aren't used to that much latitude in schlepping their station to potential advertisers. The old standby of going to car dealerships to sell ads was short-selling the station's audience. (Well, maybe higher-end cars would have worked.) Any AE will tell you that they'd LOVE to sell ads to companies that serve an affluent audience (affluent people spend more with those companies, and in turn, those companies have more advertising $$$ to spend, AND the AE gets much nicer kickbacks!) but guys like David Henry at CBS push the reps towards quantity and not quality, and the AE's struggle to get anything out there they can find, as quickly as they can, to salvage their job for another day.
To prove my point, the big advertisers on KOAI when I was there were Service King (auto collision repair,) Duncanville Ford, Ritz Camera, and quite a few mom-and-pops and startup businesses. Where's the airlines? Cruises? Vacation packages? Luxury cars? Fine dining? Hotels? High-end realtors? I quickly got the impression that NO ONE CARED. It was a dollar-a-holler. There was quite a bit of crossover sales going on, where, for example, a KLUV rep went to a potential advertiser, and found that they were more interested in buying time on The Oasis. The Oasis reps weren't taught or told to look for anything different than what would sell on KLUV/KLLI/KRLD/KVIL, etc.
As for promotions, KLUV and KVIL were well-outfitted with vans, SUVs, Marti's, even trailers and such for remotes. KOAI had a single, high-mileage Ford Expedition to handle ALL of its remotes and events. We continually used our own cars, or borrowed a KLUV vehicle (and hid it at events) to cover all we had to do. KOAI was indeed the stepchild, even though at the time, we beat both KVIL AND KLUV in 12+ for a couple of books in 2003. None of the KLUV/KVIL marketing budget trickled down to us. We were the little 27kW stepchild who was embarrassing the CBS heritage stations, but we never got the spoils for it.
Homogenizing the format by firing APD Bret Michael in mid-2003 didn't help things, either. The soft R&B was yanked, and the black audience tuned away in droves. The numbers fell steadily thereafter. After Bret left, Kurt kept the station in a 'going through the motions' level...it never grew, never expanded, never branched out, or anything. It was the air talent that kept the remaining listeners tuned it, because THEY were the only ones who understood their audience. You wouldn't believe the "love" and admiration that Lynn, Tempie, Bret and Tim got at their remotes. I wouldn't call it cult-status, but people did indeed appreciate them. Running off Lynn and Tempie because they were making too much money was just plain stupid...and poor Tim Garrison, in the middle of multiple organ transplants, getting the ax as well. At that point, there was really nothing there to listen to anymore.
So to blame the performance of KOAI strictly based on an aging audience and bad music is just not correct. This was a CBS f***-up. They couldn't make the station fit into a convenient, safe, predictable, corporate-formed mold that didn't require special treatment. This is why someone with a brain and an understanding of the Smooth Jazz audience should pick up this format and run with it. 96.7, 94.5, 105.7, 102.9 and 104.1 would all make good homes for it, let alone a few erstwhile Spanish FM frequencies.
