Let me ask you this, why then, did KRTH run those specials every year (and not just the #1's....many others as well) from 1978, the year after Mr. Hamilton arrived, thru 1990? 13 years of creative programming, before some hot shot music director came in (I don't remember his name...) and ended it abruptly by 1991?? The word is that even Brian Beirne was told firmly not to play his legendary records anymore. (I think the song was "Running Bear", and was told.) It's a simple question
Here's your simple answer:
In the 70s and 80s, we did a lot of stuff we've since learned doesn't work. I thought A to Z was genius when I first heard it (which is why I stole it from KLOS)---only to find out that the novelty, even with the Beatles, wore off somewhere around the fourth song and they went to their next favorite station for most of the weekend.
We misunderstood how people (and this phrase is key, which is why you see me use it a lot)
use the medium. They don't passively listen to whatever you serve up, they actively use the medium.
Bob Hamilton was PD at KRTH from 1977 to early 1986, when Phil Hall took over, shortly after Bob flipped the station from an Adult Contemporary station with significant gold content to a pure Oldies station. Phil lasted until 1991 and Mike Phillips (a hot shot Program Director, not Music Director). Let's see how all that went:
Bob Hamilton:
1977: 3.0 share---tied for #10 with KLAC and KFI.
1978: 2.8 share---#11 station in the market.
1979: 3.6 share---tied for #7 with KLAC.
1980: 3.4 share---#9 station in the market.
1981: 3.1 share---#9 station in the market.
1982: 2.9 share---#12 station in the market.
1983: 2.8 share---tied for 11th with KMPC.
1984: 2.7 share---tied for 11th with KKHR.
1985: 2.9 share---tied for 11th with KMET.
Phil Hall:
1986: 3.8 share---#8 station in the market.
1987: 3.8 share---#8 station in the market.
1988: 3.5 share---tied for 7th with KTNQ.
1989: 2.9 share---#10 station in the market.
1990: 1.9 share---tied for 20th (yes, 20th) with KODJ.
So the best Bob or Phil did was tied for 7th. And they both did a lot worse.
Now let's look at what happened with Mike Phillips and a focused approach:
1991: 3.8 share---#6 station in the market.
1992: 4.0 share---#4 station in the market.
...and until Robert W. Morgan and The Real Don Steele died, KRTH stayed comfortably in the mid to upper 3s and solidly in the top 10.
Today? Consistent Top 5 performance in an infinitely more competitive market....with shares consistently between a 4.5 and a 5.0 (a larger percentage of a much larger listening audience, as Southern California has grown a lot in 40 years).
Bottom line: KRTH today is the most successful it has ever been.
