Pretty much, yes.
The world really changed around then. Previously art was durable: not just books, but music, painting, architecture, and other fine “high” art was preserved. Popular culture was instant, evanescent, and disposable.
You start to see the change after WWII mostly because you suddenly start seeing the entire intellectual establishment railing against popular culture being put even with high art. They hated popular culture because it was low class, and they hated “middlebrow” culture even more, because that’s what the emerging middle classes liked and put all their money behind. Middlebrow is extremely hard to define, since it was mostly whatever the critics pointed to when they disliked something. I’ll try to make a respectable case for that side. Take the Book of the Month Club. People bought these non-intellectual books because a panel of “experts” told them they should. Sometimes the titles were displayed rather than read because that impressed others. Hollywood was a failed venture that could have been good but by the 50s was drowning in mediocrity. Television, the most popular medium, was vaudeville revived. Popular music was meaningless crooning except for that rock ‘n’ roll, which was barbarism. Nobody cared about high art, real artists couldn’t make a living unless they sold out, anti-intellectualism was the fashion of the decade.
The most important work in all of this was Dwight MacDonald’s “Midcult and Masscult,” which appeared in Partisan Review, a “little magazine” for intellectuals, in 1960. It appeared in a collection in 1962, the last moment of the past world.
Why? For one thing, every popular art got better in the 60s. Novels, tv to an extent, film, science fiction, and popular music above everything, had “new waves” where great young writers threw off the old worlds and old restrictions and gleefully embraced the popular. Popular culture not only overturned high art, it almost eliminated it except where it assimilated it. Suddenly classical music was no more than a small cult; painting was in the hands of the barbarians; modernistic architecture had destroyed downtowns; and Playboy, Esquire, New York, and Rolling Stone drove the magazine business and The New Yorker looked catatonic.
If popular art was that good, it was worth hearing or seeing or reading over and over again. People loved seeing favorite old movies and movie stars on television. The new medium of video tape allowed television shows to be showed repeatedly at the original level of quality. Oldies stations started playing songs only a decade old. Intellectuals adopted hipster irony as their default stance on popular art: I love it but I look it more deeply than you do.
And nobody in my generation cared at all what people in Dwight MacDonald’s generation thought about anything at all. Just the opposite. If they thought “a” then “a” must be wrong. All the intellectuals had disgraced themselves in the 50s by running screaming away from their principles in fear of McCarthyism and so they had no moral weight left. And they were for Vietnam. Until they weren’t, a little too late.
The world changed with The Beatles. I’ve said it before, and it works on a dozen different levels. The Beatles gave everybody leave to say it’s good, as good as any of your music, and it’s not going away. BTW, Here are 50 more groups just as good. And so are all these other things we love. We want them and we’re going to keep them, always.
That had never been done before. All the 60s rock groups thought they would have five year careers at best. Today retro is so completely normal that a backlash is forming to it. See this odd article at Slate. Retro is not nostalgia, but something new. We don’t long for a vanished past; we keep the past as alive as the present, a feat made possible by new technologies. Never been anything like it. And no adult could see it until it was all around them.
