  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.
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.
