many tv shows have jumped the shark and thus, gone downhill during the latter seasons of the series, through changing plotlines and stupid ideas, but i wanted to know, were there any shows, or do you know of any tv shows which never 'jumped the shark' ?

"STAR TREK: THE NEXT GENERATION"
"STAR TREK: VOYAGER"
"THE DICK VAN DYKE SHOW"

"Knots Landing"

It ran for 14 seasons on CBS, got rid of stale characters (an idea which wasn't always popular with fans) brought in new younger actors and current storylines, and never jumped - never even came close.

It came a little bit close in season 13 but the producers shut the show down. They fired some actors and revamped the storyline and voila...a show that stayed fresh until the end.
