Can you name any? I like Calvin & Hobbes as much as the next guy but it's really not that deep.
You are massively overstating their significance. Wrestling and comic books are both low-brow entertainment primarily aimed at entertaining kids and young adults. Like I said there's nothing wrong with that, and it can certainly be profitable, but trying to hold them up as these lofty transcendent works of art is absolute nonsense.
Given that the popularity of film and TV are rapidly waning in favour of browsing Tik Tok, especially amongst younger people, reality doesn't line up with your assertion. People will want to be distracted as society crumbles around them but that can far more easily be achieved by doomscrolling 3-4 second meme videos than watching or reading the latest goyslop.
I read Calvin & Hobbes as a kid and it's always stuck with me, but there's Peanuts, Popeye, Dilbert, Gasoline Alley, L'il Abner, Dick Tracy, Krazy Kat, Mickey Mouse, The Spirit, Buck Rogers, Tarzan, Flash Gordon, Prince Valiant, Phantom, Blondie, Felix the Cat, Little Nemo in Slumberland, Annie, Captain Easy, Zippy the Pinhead, Fritz the Cat, B.C., Trashman, the old underground stuff, Heavy Metal, RAW magazine, stuff from ZAP and witzend, Playboy Magazine comics, Saturday Evening Post comics, the list really goes on and on and are exploited well on places like Instagram now. Newspaper strips were always meant to be read by both children and adults.
The titles I mentioned (most of which are certainly not fringe) were or are wonderfully crafted, many experimental and some rather deep, but certainly engaging if it's the medium for you. These are worthwhile analog creations that are significant to millions and millions of people, possibly a go-to route for escapism.
Comics and professional wrestling are not that limited, though they can be and are often enough, being so deadline bound and all. They can be both lofty and transcendent, to be grouped in with recorded music and film, same sensations. Pro wrestling is a large scale mythical thing in many parts of the world, Western and beyond, very much traditional by now.
No one can know what the future holds, but there's a built in audience in the many millions for lots of these universal, tried and true forms of entertainment regardless of trend. It's all lucrative, practical and engrossing enough to be as sustainable as anything. Maybe there'll be a burnout or a revolt or a return, Idk it's all a toss up.
