You think that we did not use ratings, music research and all those other things 50 years ago?KM --Most of what you described is Radio from 40 or 50.years ago.
I did sales and jukebox play research nearly 60 years ago. And I was not the first. I did the equivalent of focus groups, but we called them "listener club" gatherings. I monitored airplay in other markets. I read the trades and got one of the tipsheets. I read the ratings, and even inspected the raw ratings survey data. And the people I met at conventions all did the same sort of thing.
All that has changed is the delivery system and the number of choices listeners have. But the techniques used to find out what they like and dislike in format radio are the same... but just with better technology.
A good programmer is talented. There are not many, and never have been.Programmers use much more than just instinct. They use market research, music tests, and consultants...
But there are lots of programmers who have the needed skill sets to do all the tasks a PD has to do. Most do average or even inferior jobs. They have the skills, but not the talent needed to put the skills to work in the best way.
A talented programmer is like a skilled carpenter: they learn how to use all the tools, but they apply them with a unique way of genius. Nearly anyone with even average intelligence can learn the basics of how to read ratings, dissect a music test or deal with management and the rest of the staff. Only the most talented can use those same skills to crate a #1 radio station, just as not every carpenter can create truly original works of art.
