OKCRadioGuy, I think you nailed it. Somewhere, I think in the mid to late 80s, maybe, we decided if a true personality developed a following on a station, that following might leave if the personality left (and as you all know, that's the one constant in radio).
The solution? Develop a large stable of strong personalities so one person could draw as big a crowd as another?
HECK, NO!
What you do is reduce the personality on the air so that people hardly know or care who they are listening to. Make the music the main draw (and yeah, kinda like Drake did back in the 70s) so that you can have your superstar, or a weekender, or nobody on the air and the audience will be pretty stable... they won't know what they're missing.
Then came the Sony Walkman. And now the iPod. And XM & Sirius. And 50,000 channels of internet radio jukeboxes.
...oops. :-[
It is lowest common denominator radio, and while it is safe, it is not particularly successful. As we've discussed about individual stations in the past: many are successful because they either have no direct competition or their competition is taking the same path to financial security.
Until somebody steps up, takes the risk, and re-introduces personalities in music radio (just as talk personalities resurrected AM radio, whatever you may think of their beliefs), it will always be, and the only advantage radio will have is that it's easier to tune in than pick a song on your mp3 player.
...which ain't much advantage, in my book.
And, as long as mega-corporations are juggling mega-dollars trying to stay afloat, there is NO WAY they're going to take that kind of risk. I don't know that I would, either... far too dangerous, too much potential for massive, massive failure.
If you think about it, radio has actually been trying to go MORE this way with things like the JACK format, which was / is sans jocks.
If all of your talent is on your hard drive, then you have absolute control over your talent.
Ugh... I just depressed myself...
