IIRC it was media consultant Guy Zapoleon who first pointed out a few years ago that use of radio, in terms of the percentage of available 12+ listeners actually using commercial radio on a regular basis, peaked in 1989. That [eak was reached around the time of the last big radio programming revolution, when the current generation of talk hosts and foreground music personalities began hitting the airwaves and the whole range of formats we hear on radio today began crystallizing into its current form. (Sure, there have been some variations on familiar themes, but classic hits is really the same format now that oldies was in 1989--playing the hits people in their 30s remembered listening to in their teens.) Radio is still used by most 12+ Americans...but not as often, and not for as long, as they did 20 years ago. That's what Arbitron numbers tell us.
Have we developed any new ideas, recruited new talent, sent new messages that connect with listeners as they change around us? An honest answer would be, "not to the degree we should."
Now radio still reaches a lot of people, and it's still cheaper and more user friendly than the other means of audio entertainment people are using today, whether CD changers, iPods, satellite or in-car MP3 players. We can get a lot of straying listeners back, to at least give us some of the attention they now give to other media. But we have to serve them better. What we have to do now, is get out of the rut of programming mechanically, bloodlessly and on the cheap. We need to blend the best practices of all of radio's most successful eras, including localism, personality, energy and creativity, and do it in a way that resonates with today's tastes and values. For some radio stations that'll mean minor tweaking of the kind any good PD should be doing as a matter of course.
But for some, it'll mean taking an axe to the satellite or hard drive. They'll need to begin the development of local personalities and local presence in the community that they should have been doing years ago.
For talk stations, they will need to do all that plus rethinking their basic message to see if they're turning off, or even insulting, the emerging generation of adult listeners. it'll mean reading the election returns and understanding that what your core target audience responded to and believed in 15 or 20 years ago in the age of the Contract with America is not what your target audience responds to now. The 35-54s of 1989 are now 55 to 74 and you can't sell them easily if they're still your core and you haven't recruited anyone younger. Most of today's 35-54s voted the other way and your programming needs at least to recognize that fact and stop insulting them and their outlook and values all the time when your hosts crack the mike.
