Ducktales

While reading AV's post on Cartoon oldies, it brought back memories of a simpler time. I watched one of the intros called Ducktales. Based on the comic book characters from the mind of Carl Barks, Disney updated the 1940/50s comics to a high production syndicated animated show. The show ran daily on various channels across North America, and it became extremely popular with both young males and females.
Because of Eisner's gamble, Ducktales made it possible for Disney to sell other high production shows into syndications. I still fondly remember coming home from school and watching a new episode every week. The mixture of humor and adventure was what kept me watching the show everyday. Sadly, today children's TV has turn into total crap.
Side note: Scrooge McDuck does make some appearances in the Kingdom Hearts videogame series.
Side Note: I still know all the words to the theme song and do sing it at work all the time.

And you're right their introduction mini-movies were in fact better than their later appearances.
