A column in the Star Ledger last week by its radio guy quoted a radio market analyst from Mt. Laurel (if I recall correctly) who explained what he believed to be Infinity's logic with respect to the WCBS/WJMK flips. Infinity poured a lot of promotional money into WCBS starting in the fall of 2004. They had a jingle and if you called in you could win a couple of thousand dollars. There were also billboards (one near the exit for the Lincoln Tunnel) advertising this. Then, of course, they went to the expense of hiring Mickey Dolenz to do mornings in January. Inifinity expected a return on all this promotional money, and when they didn't get it, they flipped.
Admittedly, they care a great deal about the younger demo, but, more basically, WCBS was not doing nearly as well overall in New York as WOGL is doing in Philadelphia. WCBS languished near the bottom of the Top 10 (and even fell out of it at times), managing a 3.5 or so. WOGL, on the other hand, has been at 4.0 and above in the overall for a few periods now, recently hitting a 4.6. The morning show, which was lagging way back when Don Cannon left, has come up to #5 with Ross Brittain. (Dolenz failed to move the needle at all during his 5 month stint at WCBS.)
Is this success-- whereby WOGL has consistently outperforms WJMK and WCBS-- enough? I think so. Infinity has to be shelling out some serious dough for the second year in row with the "Vacation A Day Giveaway", so if they had the slightest worry over the revenue WOGL was generating, I think would have killed it by now. As long as WOGL makes enough money to justify what Infinity is shelling out in promotional gimmicks, it's safe.
But I agree with the general sentiment of posters that WOGL, in the long-term, is not entirely safe. A few more periods of consistency would help.
