As I said, they were consumed in mass numbers in the same way McDonalds fast food is. Anime is more akin to an expensive night at a Japanese restaurant. Especially since both come from Japan, and both can burn quite the hole in someone's wallet. That doesn't mean they were bad, it's just that they were cheap, both in terms of substance and in terms of price. Cheap junk food can still be satisfying, given the circumstances. Shit, I'm shoving cheap potato chips into my mouth as I type.
Pulp as a genre was really no different from manga moreso than anime, but whereas manga (as a term for japanese comics) stuck around by virtue of being defined more vaguely (artstyle? format? anything from japan?) and thus could evolve without shedding its forebears, pulp was all but abandoned in favor of, well, comics as we know them today.
the Re-surgence of Pulp has very much been helped by the fact that the winds of time has done the heavy lifting of making sure that only really the good and decent stuff stuck around in any real capacity, whilst the mountains of bad pulp was washed away when the oceans drank Atlantis. We, as 21st century zoomers who vape and dab, are only really exposed to what floated to the top, and whats at the top is good, decent and even great.
I wouldnt put much stock in what the "high art" crowd thinks, As their tastes are usually defined by what is unique rather than what the quality of something is. Pulp being over saturated in the extreme with trash and also trash that is derivative of better stuff, unsurprisingly, makes it easy to disavow Pulp in its entirety, even if its unfair to the legitimately good stuff.
Danny pulls a reverse uno and instead embraces Pulp, dogshit and all, rather than do what any sensible human being would do and only embrace the stuff one legitimately thinks is good. both are bad extremes.
Thats the thing though, we legitimately dont know if there are geniuses in the fanfiction community who will one day come to define literature. Lovecraft didnt become famous until way after his death, and i have no doubt that it will be decades before we find out whether there were any true savants in fanfiction or not until decades from now.Calling pulps the equivalent to modern fanfiction is a bit disingenuous. I don't think an H.P. Lovecraft or Raymond Chandler level talent has ever emerged from a fanfiction community.
Rather than strictly compare it to fanfiction, i think pulp should be compared to all forms of digital writing, drawing and even animation that doesnt involve large production companies or what have you. Webcomics, webtoons, creepypastas, which in a similar fashion is comprised of mostly trash, but with some good and even great stuff, but even the bad stuff is consumed en masse by the masses.
TL;DR Most fiction is trash, be it pulp, manga, anime, movies, music, comics, porn, literature, games etc.
however...
-individual stuff can still be good or even great despite an otherwise trashy genre or format.
-people love to consume trash, regardless of quality, as long as they are entertained.
-content thats cheaper to produce has more trash, but also a higher probability of breaking the mold by virtue of the massive amount of content available, as more expensive products have more at stake to lose if it doesnt break even (why hollywood went from dramas to westerns to capeshit).
