The Disney Afternoon
Some of the early cartoon series on The Disney Afternoon came from already in-circulation cartoons, such as "Adventures of the Gummi Bears", which aired on NBC from 1985 to 1988 and then moved to ABC in 1989. "DuckTales" premiered in 1987 as Disney was focused on incorporating animated series into its portfolio in the era of cartoons; it was Disney's only syndicated cartoon series until accompanied in 1989 by "." These two shows had been packaged together as an hour-long cartoon block from 1989 to 1990, until both shows were incorporated into The Disney Afternoon in September 1990.
Carl Barks
In 1937 when Donald Duck became the star of his own series of cartoons instead of co-starring with Mickey Mouse and Goofy as previously, a new unit of storymen and animators was created devoted solely to this series. Though he originally just contributed gag ideas to some duck cartoons by 1937 Barks was (principally with partner Jack Hannah) originating story ideas that were storyboarded and (if approved by Walt) put into production. He collaborated on such cartoons as "Donald's Nephews" (1938), "Donald's Cousin Gus" (1939), "Mr. Duck Steps Out" (1940), "Timber" (1941), "The Vanishing Private" (1942) and "The Plastics Inventor" (1944).
