I reached "musical maturity" almost simultaneously with Rock Around the Clock and Buddy Holly. Anything that sounded like Big Bands or the crooners was anathema to me, and I'd switch stations if they even played a current Nat "King" Cole hit later in the 50's. And at school, I knew nobody who liked any of "my parents'" music. There was a pretty severe cut between generations.
Remember, too, that stations did not carry network shows 6 AM to Midnight. There were plenty of music shows... but the disrupting factor there lay in the restrictions of the Musician's Union (AFM) on recorded music. So the way music was presented was very restricted until the union's influence over radio collapsed as the 40's ended.
And what they did was not popular among young listeners. There were a few exceptions, but even those were driven by the adults in Top 40 audiences, not the kids.
And all along we had stations that played MOR... some included big bands and instrumentals, some just played the crooners and traditional artists. There were options for those over 35.
In the later 60's, in my home town of Cleveland, we had two R&B stations, three Top 40 ones and three MOR stations. It was not as if those folks over 30 or so did not have a place to go.
For a hit record, that is a minor part of the costs. The issue was that few young people wanted pop songs by Gogi Grant.
But Beautiful Music had moved away from those "movie soundtrack" type instrumentals to Caravelli and Frank Pourcel... orchestra leaders who could also lay down the tracks for Top 40 songs.
It depends on the cuts. I did a Beautiful Music that ran in a bunch of multi-million population markets and there were many Mauriat songs that they loved, but lots of Ferrante and Teicher and Roger Williams that that they hated. We never played Montenegro at all, as it sounded too "Hollywood".
The problem was that there were few new artists that had such broad appeal or appeal only among those over 35. But we had lots of Streisand and that stream of artist that older people did enjoy. But that is not the cause for a decline in older consumer purchases of music.
That group´was the biggest beneficiary of the profusion of FM music stations in the 70's: there were suddenly adult formats, using the term "chicken rock" or "Adult Contemporary" that came in to replace lots of Beautiful Music and MOR stations. They played songs that those over 35 loved, and those people felt little need to buy anything but the exceptional album. They had more important things to spend on than records as they were adults.
But the over-35 public found, in the 70's, a profusion of music stations playing things they liked and they had not need to buy records.
By the 70's, even AC or old line stations used research to find out what their listeners liked to hear. The idea that you have that "aides" in their 20's "chose" the music for stations like WNEW or KMPC or WGN or WIND has no basis in fact.
Agency time buyers did not determine the age targets of campaigns, then or now. I called on my first time buyers at agencies in 1964, and ever since them I would hear the same "the client's target its... " and a detail of the age, gender and other requirements of the buy. If what I was selling did not reach, efficiently that target, I was not on the buy.
You are not taking into account the introduction of the "45" with cheap and easy to use players. That replaced the fragile 78 and the constant changing of needles and the like. Remember, we call multi-cut records "albums"" because in the era of the 79, people bought 10 songs by an artist on five 78 rpm records in a cardboard album with sleeves for each disk.
There was plenty of production of instrumental pop music in the 80s, but most of it was in Europe and Asia. Much of it covered songs that were not hits in America. But we solved that by doing custom music, often enough to cover over half of what we needed.
You are forgetting all the new aritsts like Francois Goya and Richard Claydarman and many others who produced original material... from composers like de Senneville and Toussaint.
It died in the late 1980's, not the 90's. I closed my syndication firm in 1987 when I could not get new clients and some of the old ones were moving to youth formats. The real issue is that the Beautiful Music audience was aging out of sales demos, and was becoming almost all 55+.
Yes, the listeners over 55 lost most formats that appealed to them because advertisers did not buy 55 and older.
Your point about the younger agency buyers is well taken. Of course that would be true. I have heard too many radio people complain about the tastes of the younger time-buyers as well as the "kid MDs" in the 80s and no doubt had allowed that to influence my thinking more than I should have.
Most of the still-successful Beautiful outlets left that format in 1989 - 1990. Over 100. Though some had been dropping it since 1978.
I don't find as sharp a generational distinction in popular recording tastes as you have experienced. People our age grew up listening mostly to pre-rock music during our formative years. So as much as some of us would have enjoyed and chosen rock were accustomed to living with and accepting what was not only our parents' music but that of our older siblings who were loving and buying Patti Page and Frankie Laine and Kay Starr, Vic Damone yes and Gogi Grant. Then quite naturally came Domino and Pat Boone and Haley, Presley etc. and they started to buy them as some of us did as well. Which did not mean that we just rejected everything we knew and enjoyed before that! We all had our favorites but enjoyed things from different genres.
As kids we were 10 or 11 before we bought records and then just 45s. So, getting together to play our records for each other, we fleshed out our "collections" with our parent's records as well. Which ran to Belafonte, Como, Clooney, Chacksfield, Pourcel, 101 Strings, Light Classical, and so on. Just as our parents had liked some R & B or rock songs on the radio such as Louis Jordan, Roy Milton, The Hucklebuck, Dinah Washington. I remember my own father was rather partial to Good Timin' by Jimmy Jones c. 1960. But 0 when there got to too many rhythm selections on for their taste - from 1956 - then they changed the station. Or too much emotion. Just as we may have changed it if we heard too many crooners or big bands.
So those of us who liked only rock were a very small percentage - under 10%. While most of us enjoyed at least some rock but we enjoyed other genres as well. Interviewing people our age and older I have often found those eho enjoyed the other stuff as well referring to the rock as what they liked to dance to - as dance music. But for listening music on their own within the confines of their own rooms they much preferred Melachrino or Kostelanetz or Mancini. Before they liked The Beatles they were liking Connie Francis and Rick Nelson. Their "favorite bands" were Guy Lombardo and Lawrence Welk. Ray Anthony, even Glenn Miller (those were the recordings in their homes) and then they were Johnny and the Hurricanes, The Ventures, and Billy Vaughn.
But I do find there was a gap in how our age related to popular music as compared with say our parents. The latter related to songs while we related more to particular recordings. This is confirmed by much of the research done 30 - 40 years ago. Just as Your Hit Parade of radio from 1935 and later TV gave the Top 10 (or whatever fraction thereof) songs, the radio countdown shows we listened to in the 50s were about hit records, not just songs. Our parents had hit records as well but mostly the most popular songs were heard on radio done by various artists or played on the smaller stations in various recordings, many of them ETs. So there was less consensus that one particular recording of a title was in fact THE hit record. While our generation might have listened to the same songs as recorded by different artists we heard on the radio or purchased in local shops or that our friends had. But with the coming of Top 40 you had people like Bill Stewart trying to regulate the versions of recordings used on a station or group of stations to present a more consistent and unified whole. Rather than just every DJ playing what version he liked or what was given to him.
I always found much of the excitement in radio hearing the different interpretations of their material and following them and judging them. And though I did like a number of hit records more often I found that my preferred versions, either instrumental or vocal, were other than the so-called "hit" versions. So perhaps, though I always liked some rock like Fats Domino, R & B groups, I leaned more toward what was an "older" way of perceiving and judging. For instance I am familiar with Al Martino's recording of Mary In the Morning which was a hit record. Yet I have always favored the recording Ed Ames made of same which I find has more depth of feeling. And you may recall Jane Morgan's recording of The Day the Rains Came from 1958. As good as that was I always much preferred the recording Raymond Lefevre made of the same title and I think for the same company. Which I purchased when I was 11. Which btw was also a hit.
My theory, backed by research I have found, has been that the generation growing up through the depression were mostly through buying records after the mid 60s, or winding down after 1962. Because by then they had waht they wanted and in many cases much more than they ever imagined they would ever have as far as that was concerned. Which left teenagers and young adults as the main record-buying public. Who bought most of what was sold in all genres of recorded music after that.
