Im thinking about in all the ways even streaming now. Im thinking before streaming the stooges would be a good contender. Was shown in movied theaters and had reruns going all the time on so many different channels. Its a wonder life used to be spammed in november and december before the ip was taken back out of public domain.
EDITING. Im thinking more about the same thing being rebroadcast I think which is why I was thinking its a wonderful life to. So like there are only so many stooges and they get replayed a lot as opposed to like the simpsons or doctor who running for a whole bunch of seasons.
Depends on what you call a show. A good contender is the German TV show “Unser Sandmännchen” (Our Little Sand Man). It is nearly as old as there is a TV program. It shows a little “good night” story each evening for little children using animated puppets.
It started 1959, is still running daily, and so far there are over 22000 episodes.
oh I recently found out about an anime that has been running for a very long time like that. I don’t think that long though.
