"The study also tells us something fascinating about the changing parent/child relationship. Nearly two-thirds of the parents in TickPick's “Music Tastemakers” study (64%) say they've tried to influence their kids' music tastes. That's a remarkably high percentage of Mom and Dad controlling their children's music programming.
We've seen this phenomenon a lot in Classic Rock settings, where Dads seem more gung-ho about making sure junior is exposed to Hendrix, Clapton, and the Doors. And oftentimes, this translates to not only hearing the music, but seeing it live – in stadiums, arenas, sheds, and auditoriums.
Maybe it's worked. I frequently pore over Nielsen data and perceptual research for Classic Rock stations. And I often marvel at the appeal of the music and these stations among consumers well under the age of 40. They're listening to music originally released years before they were born. And perhaps much of the credit goes to their vigilant parents, many of whom were insistent they became familiar with “Dark Side of the Moon,” “Tommy,” and “Abbey Road.”
And the results continue to show up in the ratings. A story in Inside Radio today reminds us there are more Classic Rock stations in the U.S. than Alternative, Active, and Mainstream rockers – combined. As Nielsen's Jon Miller points out, “We know that Classic Rock has been and continue to be a popular format. It's the biggest rock format if you look at share of audience on a national basis,” continuing “to attract more and more younger audiences.”"
