In 1993, Nickelodeon greenlit its first fully original in-house series, "Rocko's Modern Life", produced by Games Animation with the partnership of Joe Murray Studio. Games worked on the show for three years and employed over 70 people during the course of its run. The show was canceled in 1996 by Nickelodeon due to its creator Joe Murray wanting to spend more time with his family. Following the cancellation, Games Animation produced the pilots of "Hey Arnold!", "The Angry Beavers", and "CatDog", along with the former's first 26 episodes, and the second's 13 episodes. The latter was produced by Nickelodeon Animation Studios along with the other two by this point forward.
