> Quality had something to do with it, but mostly it was the availability of new formats as a product of the FCC's severe limits on further simulcasting; AM operators did not want their AM cash cow to be hurt by a separate FM so they picked formats very different from the "big" formats on AM.
By that logic, HD radio should be a resounding success. It is not.
> Add in the fact that in the first years of FM growth beginning in 1967 the commercial loads were very low... generally about half that of that of AM stations... or less.
Again, true of HD radio - but it hasn't elevated HD radio out of microscopic ratings territory. The only reason creative formats exist at all is because stations have nothing to lose.
> You exaggerate. At the time FM began growing, AM clears had not been "broken down" and station count was about the same as it had been through most of the 60's.
Possibly - KOB sure made a mess out of trying to get WABC in Texas. Only Houston had a decent shot at it. I didn't even know about WABC until my cousins in Houston started calling me "cousin Brucie" - then when night came, out came their radio, a simple null, and I understood who Cousin Brucie was!
> Yes, stations wanted shorter songs but they made lots of exceptions.
McArthur Park by professor Dumbledore, Hey Jude, Bye Bye American Pie. Occasionally somebody would play the full Light My Fire or the full Magic Carpet Ride. Those are the only ones I remember.
> Shorter playlists came as a product of competition where the more powerful, shorter list tended to win essentially every time.
Just as it does now (note sarcasm)
> In the 70's callout research was invented to make sure we were playing the right songs.
So - when did it change to research confirming a pre-determined opinion?
> Yeah, we try not to offend people based on their language, ethnicity, race, gender and so on... as it should be.
Just because somebody is offended doesn't make them right. And creative things like Dr. Demento wouldn't make the cut today.
> There are a few poor stations, just as not all auto mechanics are good and not all restaurants serve great food.
Bad mechanics and restaurants tend to go out of business. Bad radio gets donations and stays on the air because somebody has an agenda and pours money into their hobby. They get a thrill out of hearing their own voice on the radio. Nobody else does.
> As FM stations grew, they maxed their facilities while the AMs, mostly licensed decades before, did not even cover their growing markets. AM sounded poor by comparison, and FM had more formats, and less commercials. AM started its rapid decline as a music medium and within 10 to 12 years (depending on the market), only around a third of music listening was on AM any more.
I agree that those all Japanese six transistor radios with three IF cans, limited to 3 to 4 kHz response at best, and the standard 2 1/4 inch speaker sounded terrible. But have you listened to your phone playing music lately through its speakers?
The more things change, the more they remain the same. Only the phones are thinner than transistor radios were. The problem is, portable radios just added an FM band still playing through that same 2 1/4 inch speaker, or maybe a 3 1/2 in those portable radios that just made transistor radios three times as wide and added a handle. I have a bunch of them on the attic. They have one thing in common - they sound little better than the little transistor radio. And FM is chronically out of alignment, especially on the high end of the dial. So I am not convinced sound quality had anything to do with it. Ironically, today's cheap AM radios are inherently wideband and sound great - if they haven't put in low pass filters on the audio.
.....and "YES!" there was an AM Radio single version of Iron Butterfly's "In-A-Gadda-Da-Vida" which was
about 2:53 in length. The longer version (for the Underground Hippie-Dippy Free-form format) at
17:05 in length was the "Bathroom-break Record." Oh, what a relief it is......or was??
Perhaps that was "In the Garden of Eden." Oh, well, whatever.....
It is repeating the primary KZHO-LD subchannel 9 right now, while it tests the from new coordinates. Once that is complete, Guevara and the brothers Villarreal have apparently made a deal with one another as its going to end up rebroadcasting KCOH.
Edit to add: Not sure why Joe deleted his post explaining the same. This one is a legitimate facility, covered by a CP to operate from his tower.
