context: First counterexample I could think of is the new cop show East New York where 90% of the main ensemble are middle-aged-or-older (do they all have to be elderly to satisfy your requirement) and only one or two of those isn't currently in a committed relationship (not sure if you said anything about it but that's a counter to some people's common TV drama stereotype of it being "the love and sex lives of young pretty people") >
  
  okay. it premiered this year, and I see two or three aged 50 or older as main cast. the rest are under that. I see favorable reviews, but I don't know how long it'll last. but that's something to look forward...
  Well, I almost forgot New Tricks, a British mystery crime series about retired old men assisting a female police detective. >
  
  Many “older people shows” never went away.   
  Examples:
  
  
  Games shows.  Wheel of Fortune is in it’s 40th season, and the host and hostess have not changed in decades.  Jeopardy and Price is Right make the list too.
  
  
  Old-school news shows are still on.  Meet the Press has been going strong since 1947.  60 minutes is still running too.  And all the old people I know still watch ABC, NBC, or CBS nightly news.
  
  
  Sports.  We see 61-year-old Boomer Esiason as analyst each week.
  
  
  Soap Operas.  Days of Our Lives and You g and the Restless have been goung strong for half a century.
  
  
  Sitcoms.  Maybe geared more towards Gen-X, but many are rebooted.  Full House made a comeback with the full original cast 30 years later.
  
  
  Cartoons.  We have new episodes of your grandma’s favorites: Flintstones, Scooby Doo, and Looney Tunes.
  
  
  And, if all else fails, you can watch reruns of almost any show from the 50s through present on your favorite streaming service. >

  I'm not counting hosts and hostesses in this thread but thanks for reminding me.
  By the way, daily game shows are harder to track, so I may have to search for oldest winner of Jeopardy! and The Price Is Right... and Wheel of Fortune.
  
  Old-school news shows are still on.
  
  I realize that the title is a little too broad. Still, news is news, and I wonder whether there are old/elderly news personalities reporting news outside TV studios.
  
  Sports. We see 61-year-old Boomer Esiason as analyst each week.
  
  Haven't watched sports much, and I wonder whether viewers like to see old people on TV playing intense sports. I bet golf is safer and less intense for old people to play, right?
  
  Soap Operas. Days of Our Lives has been goung strong for half a century.
  
  Daily American soap operas are dying breed, and they have diverse range of cast ensemble. Sure, they still have old actors, but I don't know which older actors have debuted their roles recently. I haven't watched soaps for a long time, honestly.
  
  Sitcoms. Maybe geared more towards Gen-X, but many are rebooted.
  
  I'm unsure whether I can count reboots, but I've seen reboots being short-lived.
  
  Cartoons. We have new episodes of your grandma’s favorites: Flintstones, Scooby Doo, and Looney Tunes.
  
  As said before, I realize my title is a little too broad. I should've included "live action" in the title. If most old actors are voicing their roles, that may reinforce visibility... or invisibility of old people. >
  
  So we don’t count game shows, news shows, or cartoons.
  Sports, I wasn’t talking about players, but rather commentators and analysts.  Of course we don’t have 70 year olds in professional sports, but they do have a strong on-screen presence.  Guys who played in the 70s and 80s are still on camera talking sports.
  Soap Operas aren’t dead.  They have generally a mix of old and young actors

  I'm unsure whether I can count reboots, but I've seen reboots being short-lived.
  
  The reboot I cited (Full House reboot) lasted 6 seasons. And starred Bob Saget, Dave Coulier, and John Stamos, among other old people.

  If most old actors are voicing their roles, that may reinforce visibility... or invisibility of old people.
  
  Sure they are.  
  
  
  Rob Paulson is 66 and still going strong.  He voices several characters in the 2023 animaniacs.  
  
  
  Most of the original voice cast of the Simpsons are in their 60s and 70s... and they’re cranking out new episodes.
  
  
  Tress McNeil is 71 and going strong.

  Okay, so you are looking for Live action and fiction:
  
  
  Carol Burnette is 89 and she played a major role in the 2022 Better Call Saul season.  Other starring characters in the show, like Jonathan Banks, are in their 70s.
  
  
  Betty White dies last year, but she had a major on-screen presence well into her 90s. >
  
  
  Soap Operas aren’t dead. They have generally a mix of old and young actors
  
  Oops, I meant American soap operas. Two on CBS, one on NBC, and one on ABC. The rest ended years ago. >
  
  C’mon...  I made some good points.  Even if you win’t give me the delta, at least hit the upvote button. >
  
  They revived Curb Your Enthusiasm, where the main star is over 70 and a lot of the core cast are in their 50s. Even when it first started in the original run Larry David was 53.
  Hacks is pretty fun, but it is one of those pairings of one young and one old (70), so that might not fit your preferences. That said, a lot of the Jean Smart's fellow performers that she interacts with in the show are of similar age.
  Dead to Me starred Christina Applegate who was 50 and Linda Cardellini (who you probably think is too young at mid-40s).
  I don't know why you feel the need to exclude streaming services. They are basically the cable companies of modern times. I'm sure at least some of those that I mentioned above were streaming shows. To be honest, I usually don't see shows until they are "syndicated" on a streaming service.
  Also, is it really true that there were more shows about old people in the past? Just because there were a few like The Golden Girls doesn't mean that the majority of television from the time was also just as young as it is today.
