DuckTales
DuckTales is an American animated television series, produced by Walt Disney Television Animation and distributed by Buena Vista Television. The cartoon series premiered on September 18, 1987, and ran for a total of 100 episodes over four seasons, with its final episode airing on November 28, 1990. Based upon "Uncle Scrooge" and other Duck universe comic books created by Carl Barks, the show follows Scrooge McDuck, his three grandnephews Huey, Dewey, and Louie, and close friends of the group, on various adventures, most of which either involve seeking out treasure or thwarting the efforts of villains seeking to steal Scrooge's fortune or his Number One Dime.
Fox Kids
In 1988, Disney purchased independent television station KHJ-TV in Los Angeles, changing its call letters to KCAL-TV the next year. The station's new owners wanted "DuckTales" to be shown on KCAL, effectively taking the local television rights to the animated series away from Fox-owned KTTV. Furious at the breach of contract, Diller pulled "DuckTales" from all of Fox's other owned-and-operated stations WNYW, WFLD, WTTG, KRIV, KDAF and WFXT in the fall of 1989. Diller also encouraged the network's affiliates to do the same, though most did not initially. As Disney went forward in developing "The Disney Afternoon," Fox (whose schedule at the time was limited to prime time programming on Saturday and Sunday nights) began the process of launching its own children's programming lineup.
