and yet we have a shit of a series in King of the hill still running.
Well, I won't delve into the quality of King of the Hill. However, I will say that there is a difference between the two shows. Even though Duck Tales was a great success for Disney, it's death was inevitable for one reason: syndication.
King of the Hill was a network funded television show, so as long as it got good ratings, FOX was always going to renew it. If the Simpsons had been a syndicated show, I doubt it would have lasted 1/8th as long as it has.
DuckTales was a part of a 2 hour-long syndication package, and once the show became the oldest show running on the block, it had to go in favor of newer, more potentially-profitable programs.
Two shows that lasted forever were Teenage Mutant Ninja Turtles and Garfield and Friends. Those shows lasted for 7 or 8 years or longer. Why? Because they aired on CBS Saturday Mornings on a dedicated network block instead of syndication.
That's the sad reality of syndicated television.
