If true, why can't Audacy, Cumulus, Iheart and others who are "broadcasting experts" do it?
It takes a different sales approach and the corporate structure and mentality don't seem to adapt well to it. In the case of the successful stations of this type, we can look at Buddy Shula as one... if not "the" best example. Buddy is in contact with advertisers, builds confidence, and is involved in programming. We also have "b-turner" in Texas where he devotes lots of time to relationship building with clients and establishing trust in the station.
The large companies are not built and structured to single out individuals to be specialists in old-leaning formats and to give them special work conditions that likely are headaches for large HR departments and don't fit in the hierarchical system of group owners.
They own clusters of stations serving different demos. Oh that's right, go back to your premise that it's too hard and expensive. Older demos don't respond to ads fast enough, so it's not cost effective. You've spewed that reason on other threads ad nauseum...
I have not said that "older people don't respond to ads fast enough". Don't misquote or misinterpret other posters.
My belief, based on working mostly with agency accounts, is that dollars are best spent against the consumer groups most likely to spend the most. However, at the local level where direct accounts are not as involved in differences in response levels, most businesses welcome consumers of any age. But local direct requires a totally different sales approach than agency sales or sales to businesses that have their own ad department.
But for small groups and "non-corporate" owners there are many reasons to go after the over-50 group in some markets. You have to see the right conditions, which include a thriving local business community and a station owner willing to spend a higher percentage on sales than would be the norm with agency-appealing 25-54 and 18-49 targets.
Another example would be Lotus' purchase of KFWB in Los Angeles. The station is a medium power AM, but it covers the core Hispanic areas of the market pretty well. And nobody plays true Regional Mexican "oldies" for first generation Mexican immigrants over 50 or so. With the market growing towards being 50% Hispanic, there are now enough businesses that want every portion of that market. There are loads of Hispanic-owned businesses and services, and many non-Hispanic businesses that realize that they have to attract Hispanic consumers or they will eventually die. Lotus is a specialist in selling niche formats such as Spanish language sports and Farsi programming in LA, and they know how to focus on direct sales. They are very profitable; like Buddy, they know the market and are willing to develop a sales team and attractive-but-low-cost programming.
Oh, and what I have said is that the older a consumer gets, the more they tend to have long-term preferences for brands and services, and it takes more promotion to "sell them over" to a different business. It is not impossible, but it takes longer and sales people who know how to work with older leaning formats build the right expectations among clients. Again, not easy for big radio groups that have a hard time managing "special people for special situations".
