DePatie and Freleng also produced several Saturday morning cartoons, including Here Comes the Grump, Bailey's Comets (created by DePatie and Freleng "in association with Joe Ruby and Ken Spears"), The Houndcats, The Super 6, Super President (an Old Shame for DePatie; he admitted he was relieved when it was cancelled after one season), What's New, Mr. Magoo?, Baggy Pants and the Nitwits, The Oddball Couple, Return to the Planet of the Apes, The Fantastic Four (1978) and the later episodes of Doctor Snuggles, taking over from Topcraft. They also took the reins for TV adaptations of Dr. Seuss books after Chuck Jones's studio closed down. They would also animate the opening theme to I Dream of Jeannie (though not its Animated Adaptation, Jeannie) and the "Time for Timer" and "The Bod Squad'' PSAs for ABC.
Their biggest success in TV, however, would come after DFE was sold to Marvel Comics, following Freleng's retirement. The company was renamed to Marvel Productions Ltd., and produced some of the most famous animated shows of The '80s, including The Transformers, the first few seasons of G.I. Joe: A Real American Hero, and Muppet Babies (1984), as well as a small amount of Marvel superhero programs (including Spiderman And His Amazing Friends).
In 1986, as Marvel Comics entered into financial trouble, Marvel Productions was sold to New World Pictures, who renamed it to New World Animation in 1993. Several years later, New World was sold in its entirety to News Corporation, who in turn placed the Marvel/DFE catalog into Saban Entertainment. Saban merged with Fox's Children's Entertainment division that year to form Fox Family Worldwide, Inc. Finally, in 2001, Fox Family Worldwide, Inc. was sold to Disney. Currently, with some exceptions, most of the all-original DePatie-Freleng and Marvel Productions library are owned by Disney, through Marvel Animation.
One of the company's animators, Nelson Shin, was also the creator of the Star Wars Lightsaber effect for A New Hope (of which the studio received credit for) and the founder of South Korean animation studio AKOM.
