Klasky Csupo is an American multimedia entertainment production company which specializes in animation and graphic design and located in Hollywood, Los Angeles, California. It was founded by producer Arlene Klasky, animator Gábor Csupó and their nephew Attila Csupó, hence the company's name.
The company was founded by Klasky and Csupo in a spare room of their apartment in 1982, and grew to 550 artists, creative workers, and staff in an animation facility in Hollywood. During the 1990s and early-mid 2000s, they produced and animated era-defining shows for Nickelodeon such as Rugrats, Aaahh!!! Real Monsters, The Wild Thornberrys, Rocket Power, As Told by Ginger and All Grown Up!, as well as Duckman on USA Network. In the mid-2000s, Nick ended their long-running partnership with Klasky Csupo and its shows ceased production.
