Do you think Gilligan's Island, The Flintstones, the old Popeye cartoons, I Love Lucy, The D*** Van Dyke Show, the old Woody Woodpecker cartoons, The Jetsons, Three's Company, The Partridge Family, Top Cat and The Honeymooners will still be known 50 years from now?

Probably not. I don't think most people under 20 would know most of those franchises now.  The lack of need to watch repeats and whatever was on the TV thanks to streaming has hurt the longevity of shows 

Some of these area already gone just as much as Howdy Doody or Captain Kangaroo. My teens (and their friends) seem to really enjoy movies from the 80s/90s but really nothing older than that. And definitely not TV shows older than that. The oldest they seem to go in shows is the Simpsons and the Office.

Flintstones still sell a ton of vitamins and fruity pebbles for a show that's been off the air for decades

I believe the one episode of the D*** Van Dyke show “ It may look like a Walnut “ could single-handedly keep the show alive forever : ) Required viewing for comedy

They will fall from mainstream consciousness, but someone somewhere will discover them and a cult following will emerge potentially or eventually. Outer limits, the B/W are more memorable than the ones from the 90s-00s. Look at books we still reference some authors and their works outside of academia. If anything someone or people will keep the memory alive too, by reboots or their own inspired content. The real question is how do you keep these shows accessible to new audiences? There's a line of reward/risk for providing access to all this media.

I remember Captain Kangaroo fondly, and Howdy Doody to a lesser extent because it was already off the air when I was born, but I saw clips of it, so it wasn't exactly obscure. If we remember all that stuff 50 years on already, why wouldn't people know about it 50 years from now? TV history is still history. It doesn't mysteriously disappear just because people that grew up with it get older and die.

Reminds me of that Woody Allen movie and his take on nostalgia for things before your time where his stand-in du jour Owen Wilson wants to stay in 1920’s Paris when he inadvertently finds himself there. But the girl he is sweet on—the French actress’ name escapes me at the moment—she wants to go back to the 1890s, iirc, cuz her present is the ‘20s and she doesn’t think much of it and thinks the Belle Époque is really the time to be. That scene has really stuck with me. Taught me to be much looser with what others enjoy and like from the past that may not be my cup of tea. But also to be more wary of some who might have inadvertently crossed back into my time cuz of how psyched they are for things as they are today.

Depends if they are rebooted, which I assume someone will try to do when they need ideas. If they aren't, they will fade away. I watch old TV shows and my son still doesn't know what any of them are even with them being on TV in the living room.

Cartoons definitively. Live action show not likely, well maybe The Addams, The Munsters, I Dream of Jenny and Bewitched.

Besides the Saturday cartoons, I dimly remember watching wrestling, roller derby, Abbot and Costello, and The Bowery Boys or Dead End Kids. Even The Little Rascals would pop up occasionally.

The cartoons and I love Lucy perhaps. 

Yes. Some full episodes of them on Youtube have views in the hundreds of thousands and clips of them in the millions. Unless some kind of mass internet wipeout happens the shows and fans will still be around.

i think not and reason why is because of the rise of streaming. as you said, the flintstones was well known to kids because they reran in on cartoon network/boomerang. i was born '95 and still remember flintstones, jetsons, top cat, huckleberry hound, wacky races, etc lol (as well as all the shows you mentioned, except i've never heard of the partridge family). that's because i watched tv a lot and the shows were still on tv on various channels. but now youtube, netflix, twitch, tiktok, etc exists. people are used to new new new, not watching content from X+ years ago. people are not limited anymore to whatever is on tv, they can choose what to watch from an ever expanding pool of shows and movies, plus regular content creators. i think if things continued on how they were, with tv still being the dominant way of media consumption, then yeah, in 50 years, i'd bet a lot of people would still remember those shows. but things have changed. outside of maybe some parents telling their kids about those old shows and watching it with them, i can't imagine they would gain a lot new fans or anything. at most these shows will just be a mildly entertaining wikipedia page someone stumbles on while doing research for an irrelevant topic. or if anything, maybe some elderly fan will make a clips compilation for these shows and post on tiktok or whatever social media site exists in the future.

Some will be known as icons/properties (Popeye, Flintstones) but most of those will fade into the ether. Of that list I feel like only I Love Lucy stands a chance of maintaining some form of relevancy

I don't know. They'll probably be as obscure as they have become in the streaming era. I also think the "prestige" era shows will be even more obscure as streaming services die or jettison content.

I have strong opinions about this.

The animated shows could easily have a revival if they get a movie or remake series with a toyline. If not, they'll become very niche. I Love Lucy is a classic and will always have some fans. A lot of those sitcoms are available on streaming, which will bring in a few new fans.

I'm gonna say no because I do not know what Top Cat is and am 56 yrs into this journey

Definitely they will live on , on some streaming platform forever, which is Great!

Most of those are already forgotten, really. I’m in my 30s and I have only seen the cartoons and I Love Lucy.

No, I doubt many people know them outside of family guy references...which are probably already on the way out

No, each subsequent generation has cared less and less about history.
