This is sort of a "Chicken or the Egg" topic-were WARM, WABC, KHJ, etc big because of the brand..or were they big because of the personalities. In most cases it was the personalities. But the branding brought the personalities.
In all honesty, I cannot think of a format in this market that was ahead of its time, except for WARM back in the late 50s and early 60s, which is when they started rockin' and rollin' while everyone else was still playing Patti Page and Tennessee Ernie Ford. Once WARM set the standard, the wannabes lined up one after another. And one after another, they largely failed to get anywhere near WARM number-wise. WARM, again by design and forethought, managed to get so far out ahead of all other stations in the market that no one caught them for over 25 years.
Now, about Harry and Terry. Terry was treated horribly. He sued. He won. Small consolation, I suppose. Harry made his own bed. Leaving WARM was an enormous mistake. He really should have known better.
Then there's KHJ, WABC, etc.
My take on it, Norm, is that it was more of collaborative effort, especially with WABC and KHJ. These stations were built and tailored for success from the ground on up. Sure, they had big personalities, but formats were such that there was virtually no wiggle room. Where there was wiggle room, it was limited and built into the format for specific people. Ingram likely had more than a Ron Lundy...and I'd bet he had more than Harry Harrison, too. So, and if you go back and do even minimal research on this, the formats were meticulously designed THEN the personalities were found to fit the format, and not the other way around. BTW, I sort of agree on Bruce Morrow, it's time he moved gracefully away. As to how he sounds, I can only guess that Sirius(which I have and love)lacks the mountain of processing that the stations under discussion here once had. I've mentioned this before, but it's true. The first time I did an off-air aircheck at WARM, I thought - who the hell is that? It sounded tremendous, so unlike me that it was a little scary.
Not to be ignored is that these guys all had producers/engineers/board ops who were of the highest talent and skill. They could have likely made the guy who delivered the Danish every morning sound half decent. These stations also had money. Enough so they could pick any major market talent in the nation and recruit them. Can you imagine getting a call from WABC? While your imagining, think of all the hundreds of very talented jocks who busted their humps over the years to get a shot at a station like that and never came even close.
