"Flesh out" what you are saying here. Are you trying to tell us there are surveys that show 92% of the public LIKES the programming status of broadcasting today?
Is it possible what the numbers tell us is that even though a lot of people are highly disappointed with what comes out of the speakers and headphones, some how or another 92% of them reportedly end up listing at least once every week... even if just for 10 or 15 minutes... whether they like it or not?
I've lived through all but the very earliest of radio's so-called Golden Eras, and I would have trouble accepting a statement that at any one time in the history of broadcasting that 92% of the population LIKED the content, the state of radio.
Trying to find reliable data of deafness in our country is a bit of a fools errand because there are so many definitions of who can and cannot hear (or hear well enough to 'function'). It looks like may 6% of our population may not have the ability to listen to radio. But 92% LIKE it?
Some "experts" on radio who post here that I have great confidence in tell us repeatedly that radio has no place for listeners over 55. Thus there is no programming aimed at people 55 or older for all practical purposes. According to the 2010 Census, 18.5% of Americans are 60 or older. Radio has no interest in or use for people that are 18.5% of the population, but you tell us 92% of the people are happy with radio every week.
As we say out here in the rural South: "I may have been born at night.... but it wasn't LAST night."
