Lord and Miller first developed the series' concept while at Dartmouth College in the 1990s, later pitching it to executives at American network Fox Broadcasting Company, who ultimately decided to pass on the program. It was later purchased by cable channel MTV, and was produced between 2002 and 2003. The show's design is heavily stylized and its animation style limited, emphasizing humor and story over visuals. The "Clone High" theme song was written by Tommy Walter and performed by his alternative rock band Abandoned Pools, who also provided much of the series' background music.
