Tough to tell what will survive. Popularity of things from the past depends upon so many variables. You need something so immensely popular that it was copied/reprinted/duplicated a LOT, that wasn’t so dependent upon its time (knowledge of current styles, events, etc) that it will still be relatable, and which will last through years of changing mores, tastes, and the whims of history to continue on. There were a LOT of popular authors from the 19th and early 20th century who are utterly forgotten today. Lots of popular and important social movements that are simply footnotes, and celebrities, politicians, actors, and the like who people thought would be remembered forever.
The current popularity of these people or works is nota good guide to their future fame. But look at what HAS survived – James Fenimore Cooper, despite the assaults on his prose by folks like Mark Twain. Mark Twain. Edgar Allen Poe. Sir Arthur Conan Doyle’s Sherlock Holmes looks damned near immortal, although other Doyle works have fallen. Some works by Verne and H.G. wells Even H. Rider Haggard (you’ll notice I mainly mention fantastic fiction. Tough. I like it).
With more recent writers, I’m amazed how many science fiction authors who were big in their day have disappeared. But I suspect Heinlein may survive, even though he is being overtaken by events. Some of Clarke and Asimov, although by no means all. Edgar Rice Burroughs is, I think insured immortality through Tarzan and maybe John Carter. Probably Robert E, Howard, through Conan the Barbarian (And who would have predicted that? Howard only wrote the Conan stories the last few years of his life, committed suicide at 30, and hardly had anything published outside the pulp magazines in his lifetime. His fame is the result of others re-publishing his work, unearthing unpublished stuff, elaborating upon his stuff, and putting it in other media. It’s now achieved a Critical Mass necessary to survive for a time. How long that will be, I have no idea)
Stephen King has a good chance of being read in the future. There just so damned much stuff by and about him in print, so many movies and shows based on him, that it’s hard to believe a scintilla at least won’t survive for quite a long time.
As for movies, I can see the Wizard of Oz, The Maltese Falcon, Casablanca and a select few others lasting a long time. I’d like to think Stanley Kubrick’s films and Akira Kurasawa’s films will live on, but I’m not sure they have a broad enough appeal to be really popular pop culture I could easily see A Clockwork Orange, once outrageous for its imagery and themes, now seeming much tamer, vanishing altogether, except to enthusiasts.
I suspect most TV dramas, like the old-time radio dramas that still exist as sound recordings, to disappear completely, except for their coterie of enthusiasts.
