Astrology has been going on for centuries, maybe millennia. Homeopathy for 150 years. Bullshit doesn't have an expiration date.
What does that have to do with assessing whether vinyl rates as a "fad?"
Whether something is "b.s" doesn't entail it's a "Fad." Generally, a "Fad" is something that becomes very popular for a short period of time.
Classic examples: Hula-hoop, Pet Rock, Pokémon, Beanie Babies, Mood Rings...and of course various fashions etc.
The longevity of Homeopathy and Astrology clearly aren't "fads" in this common understanding. The truth claim of a fad isn't the point.
It's the intensity of interest combined with a relatively short period of time. There is nothing "b.s." about a hula hoop. But intense short-lived popularity made it a "fad."
Vinyl being on an unbroken upward trajectory for 15 years, still with no end in site, doesn't seem to fit the usual life-span of a "fad." It seems better assessed more along the trajectory of a technology life cycle. The upward trend alone is already approaching the length of time of the
ascent and descent of DVDs!
There IS something more to this, and it HAS been explained with real experimental support. It's interesting and a bit distressing to me that no-one has engaged the Uwins experiments I linked earlier.
I guess no one engaged that experiment because it doesn't really address or explain the increased popularity of vinyl.
IIRC, the experiment suggested that in blind tests people will choose digital versions over vinyl for sound quality.
But the popularity of vinyl has far wider and varied explanations than the question of sound quality - the tangibility aspect, the collectibility, the connection it gives people to their music collection, the way lots of people find they focus more in attentive listening to vinyl, the allure of turntables, supporting artists (vs streaming residuals), taking a break from the digital world, the communal aspect of record stores/vinyl community, etc.
Also, even in terms of sound quality - yes there is certainly also many who say "I prefer the sound when I'm listening to vinyl." But remember, even IF they are mistaken about WHY they perceive preferable sound quality from vinyl (e.g. expectation effects), it's still their subjective perception, and hence another motivation. So "people think vinyl sounds better" still goes in to the bin motivations for "why some prefer to buy vinyl" (which, insofar as they are sincerely 'mistaken,' is different from, say, simply ascribing "hipsterism)."
