Klasky-Csupo, Inc., (stylized as KLaSKY CSUPO INC., doing business as Klasky Csupo, /klæski ˈtʃuːpoʊ/ ronunciation_respelling_key">KLAS-kee CHOO-poh) is an American animation studio located in Los Angeles, California. It was founded in 1982 by producer Arlene Klasky and Hungarian animator Gábor Csupó (hence the company's name) in a spare room of their apartment and grew to 550 artists, creative workers and staff in an animation facility in Hollywood.
During the 1990s and 2000s, they produced and animated era-defining shows for the children's network, Nickelodeon, such as Rugrats (which was one of the channel's original animated series, known as Nicktoons), Aaahh!!! Real Monsters, The Wild Thornberrys, Rocket Power, As Told by Ginger and All Grown Up!. They also animated the first three seasons of The Simpsons for 20th Century Fox Television and Gracie Films, as well as Duckman on USA Network. In 2008, Nickelodeon ended their long-running partnership with Klasky Csupo and its shows ceased production, resulting in the company becoming dormant for four years. In 2012, the company reopened and began production on a CGI-animated reboot of Rugrats, which premiered in 2021 on Paramount+, the streaming service of Nickelodeon and its parent company Paramount Global.
