No, people want dependable, familiar products most of the time. Experimentation and pioneering is saved for special moments. And this condition increases as consumers age due to experiences, good and bad, with trying new products or new implementations of old ones.
I work in a department mall store and we always refresh and update our endcaps, our presentations, our features and visuals. If we don't, #1 the areas will empty out, #2, the customers will notice and say to themselves, don't these guys ever have anything new, it's the same stuff everytime I come here. And if we don't update things, we lose customers. It's been told to us numerous times by merchandising execs and store visits by regionals as suggestions to improve sales. This cannot be disputed.
Same thing happens in radio. People notice that everytime they "shop" your frequency, it's the same songs, so they switch, tuneout or lower the volume. People do not like the same thing over and over and over again, even if it's over the long haul, not to mention short term exposure. They don't! People like change, people like variety and people like to have fun. Currently (with few exceptions) radio does not offer that. You can claim this or that about the ratings, but overall, people are dissatisfied with radio and it's presentation, just like television and it's "flooding of the airwaves" with stupid reality shows. Look what happened to the wx channel and Direct TV. Great example there. It cannot be denied.
