Thank you, Michael! It sounded like L Keller was saying that KFRC had an FM at the time and surrendered to it. From an outsider's viewpoint, I thought what really did in KFRC was "The Game Zone". 12+ still looked pretty good up to that point.
Semoochie:
That's the perception...but it's not quite reality.
KFRC's peak was in the April/May 1978 book...#1 12+ with an 8.4. Les Garland was the PD.
Just two years later (April/May 1980), KFRC had a 4.4. That's almost half. Les was out, went to work doing promotion for Atlantic Records before landing the MTV gig, and they hired Gerry Cagle.
In those two years, KYUU had gone from a 1.7 to a 3.6, and KSOL from a 2.5 to a 4.3.
Cagle decided to defend against KSOL.
July/August '80 was a transition book...Cagle's game plan wasn't in action yet. It was even worse than April/May. KSOL with a 4.8, KFRC with a 4.0 and KYUU with a 3.7.
October/November '80 saw KFRC and KSOL tied with a 5.1. KYUU had fallen back to a 2.9. For the rest of Cagle's run, KFRC would be between a 4.5 and a 5.4, finally putting KSOL in its rear-view mirror in the Summer '82 book.
But what worked for Gerry was that hard rhythmic approach. This was when most Top 40 was playing Air Supply and Juice Newton. In '83, when the CHR revolution came along, Gerry had to play the hits, and that meant KYUU could stick to mass-appeal hits, play most of what KFRC played, and do it in FM stereo.
In Winter of '83, it was KFRC 4.1, KYUU 3.7. Spring '83, KFRC 4.3, KYUU 3.2.
Summer '83 was KFRC 3.9 and KYUU falling to a 2.4....but KSOL was gaining with a 3.6.
Fall '83 and Winter '84 were the books that sealed Cagle's fate. Fall '83 had KFRC 7th with a 3.0, being beaten by KIOI (which was what we'd call a "Hot AC" today) at 3.2 and KYUU two-tenths behind at 2.8. KSOL was 3rd with a 4.7.
Winter '84 was a tenth of a point better for KFRC, at a 3.1...but worse in every other way. They'd fallen to 9th, with KSOL at a 3.8, KYUU with a 3.5 and KIOI with a 3.4
That was it for Cagle. He was gone in mid-March of '84.
Mike Phillips was next. He made the mistake of going totally by the charts and ignoring rhythmic product that wasn't mass-appeal crossover. Now there was no difference between KFRC, KYUU and KIOI apart from Dr. Don on KFRC and the other guys being in stereo.
Summer '84: KFRC tied for 13th with a 2.6. KSOL 2nd with a 6.1, KYUU fourth with a 3.9, newcomer KITS 8th with a 3.1 and KIOI 9th with a 3.0.
Fall '84: tied for 9th with a 2.7. KSOL third with a 4.0, KYUU fourth with a 3.4, KIOI tied for 7th with a 2.8.
It was at this point that Walt Sabo, who was consulting RKO, began putting the pieces in place for the Game Zone.
Winter '85, before the launch of the Game Zone, was a bit better...8th place with a 3.1, but KYUU was 3rd with a 4.1, KIOI was fourth with a 3.5 and KSOL was fifth with a 3.5.
And then, the Game Zone.
First book, Spring 1985: KFRC 1.9, tied for 20th with KLOK-FM and KKHI AM/FM.
Second book, Summer 1985: Worse. KFRC 1.5, 22nd place.
Third and final book, Fall 1985: Marginally better, but still awful. KFRC 1.7, 21st place.
In mid-November, the Game Zone was dropped, PD Dave Sholin brought back Bobby Ocean and tried to make the thing fly again, but never did better than a 1.7.
So, KYUU had been a threat for a long time, passed KFRC in Winter of '84 and never looked back. KMEL debuted in Summer '84, but didn't beat KYUU until Winter of '86.
And KFRC...well, looking at the huge audience loss between Spring of '78 and Spring of '80, you could make a case that had Gerry Cagle not decided to go after KSOL, the decline would have continued...and KFRC would have been, like most AM Top 40s, out of the format by 1982.
