On the Andy Griffith show, I think they were still making references to having just talked to Floyd the Barber several years after Howard McNear had died.
Granted, that could be considered a tribute especially in a comedy where it's depressing to talk about characters dying.
Aside from killing off characters, especially on older shows, there was a tendency to never speak of a character again if the actor left the show, almost as if the character never existed. Again, from TAGS, there was the decision to never mention Elle Walker again after Elinore Donahue left after the first season.
