Frank, let me answer that question with a comment and what I hope is some clarification.
I don't believe that Oldies76 or myself (or anyone on here that enjoys specialty weekend programming), really believes that a successful station should ever change their format. That's not to say that every so often they can't implement little tweaks here and there to keep them from stagnating.
I realize we're talking about K-Earth, but another successful station in the market is THE SOUND. Great station in fact. I've heard them devote entire weekends to having KMET jock reunions. Has any of that hurt them? If so, how?
Hey, for the sake of their own successful track record and definitely from a financial standpoint, I would never advocate K-Earth changing what has obviously been working for them. I would certainly not vote to do a 1955-1985 #1's of L.A. weekend --- at least not with the demographic that's been tuning in for the last 20 years. That would go over better with the die-hards once I attempt to upload all those files on to YouTube (if I can get past the potential music licensing issues, otherwise I'll buy both an ASCAP and BMI license and start my own website). I think that particular period of KRTH and the first 30 years of Rock & Roll needs to be preserved for the ages, and it should.
Someone else a few posts back made a point that K-Earth running a special on a holiday weekend where there aren't as many listeners, isn't gonna drive everybody away. I would agree. Back to Frank's question ... I don't think it would harm K-Earth, or its listeners or advertisers or CBS one little bit if they devoted a Labor Day weekend to bringing back Brian Beirne and a few of the legendary air personalities of the past, and played the next 30 years of Rock & Roll, covering 1985-2015, which would fall squarely into their demo. Or if 2015 is too risky for them, then the first 25 years up through 2010, or maybe 20 years covering the music through 2005. I'd even take a 15 year span. I'm not talking about dragging out the old jingles or tapes of old shows. I'm talking about the listeners reconnecting with voices that were recently there, but no longer; and doing it as a one-time thing. Gee, what could it hurt? That's not asking that successful station to change their format. In fact, it's to shine a spotlight on themselves to show listeners what made them so successful. Yes, bring Jhani Kaye on too.
