You also seem to assume that oldies radio is the best or only way to reach older consumers. Actually a lot of money is spent to do just that. Some of it goes to talk radio or AC, which includes older listeners but not exclusively. A bigger part of the ad budget for seniors goes to cable and print. Even businesses that want older customers have decided there are better/more cost-effective ways to advertise to them.
This is an excellent point that has not been made in recent posts.
I looked at one market where I have Maximiser numbers and where there is a well-performing classic hits staiton, Dallas and KLUV.
The 50-64 shares show that oldies, on KLUV, has just 10 shares in that demo. While it is definitely #1 there, the next 9 stations in the demo have nearly three and a half times the audience of the #1 station, and KLUV only has one of every 10 listeners on the average.
The other formats represented in the top 10 in 50-64 have formats like talk, country, news, AC, Christian and classic rock.
As you say, oldies is not the only format that reaches this group. In fact, if an advertiser only uses oldies, they miss most of the market here. The advantage of many of these formats that also deliver 50-64 is that they are generally strong (except for all news) in 25-54 and allow an advertiser to get a "bonus" of 55+ when buying 25-54.
Since stations price based on the cost per point in the demo the advertiser wants, not on 12+, an extra "free" bonus audience really helps some formats get on buys because they add useful listeners with no extra ad investment.
