"Family Guy" (3 years)
"Family Guy": FOX canceled the series at the end of its third season, in Februrary of 2002. Then the show found new life in reruns on Adult Swim — and, more importantly, as Peter Griffin explained in the first episode back, FOX put on a whole lot of other shows that died quickly — and the series returned in May of 2005, and is now the anchor of a FOX Sunday lineup that includes two other Seth MacFarlane animated comedies.
