An interesting discussion. Is there a right way and a wrong way to "evolve" a format consisting of entirely library material? Are there such formats that simply CAN'T be evolved, as RockofHBG implies?
Consider "Oldies"...in its original form, a "library" format that played in most markets around the country un-changed for 25 years! We all know the formula: a core library from the Beatles-Stones-Beach Boys-Motown-Phil Spector era of 1963-69. Sprinkle in a few 55-62 early rockers like Elvis, Chuck Berry and Buddy Holly and Doo-Wop groups like the Platters and the Drifters. Some stations played a few carefully-selected artists from the early 70's like the Jackson 5 and Jim Croce. But that's it. This format performed fabulously year after year, delivering great numbers and sellable demos. Why mess with it?
Then...as the late 90's approached...alarm bells began going off in corporate offices nation-wide...
just like the anguished cry from the bridge of the Titanic on that fateful night...."DEMOGRAPHIC ICEBERG DEAD AHEAD"...The Boomers were aging out of 25-54!
A good friend of mine programmed such a station in the 90's. When he saw the demo problem coming, he began slowly, carefully and cautiously evolving the station. Out went Buddy Holly and the Platters and in came 70's mainstays like Elton John, Bob Seger and the Bee Gees.
What happened? The numbers went DOWN! the Boomer P-1's didn't care for the 70's stuff, and while they still listened, they didn't listen as long or as often. So my friend beat a hasty retreat and went back to the original formula. The ratings promply went back up.
But it wasn't to be. The "Demo Iceberg" remained and the company eventually blew up the station in favor of a younger-targeted format. My friend, thankfully, landed on his feet.
So are programmers like Chris Tyler at The River and Ross Murdock at The Peak actually doing the right thing by slowly and carefully adding newer rock? After all, to a 30-year-old, bands like Third Eye Blind and Green Day, popular in the '90's, are "classic." Is there a right answer?
