Early episodes based much of their comedy on Stewie's "super villain" antics, such as his constant plans for total world domination, his evil experiments, plans and inventions to get rid of things he dislikes, and his constant attempts at matricide. As the series progressed, the writers and MacFarlane agreed that his personality and the jokes were starting to feel dated, so they began writing him with a different personality. "Family Guy" often includes self-referential humor. The most common form is jokes about Fox Broadcasting, and occasions where the characters break the fourth wall by addressing the audience. For example, in "North by North Quahog", the first episode that aired after the show's revival, included Peter telling the family that they had been canceled because Fox had to make room in their schedule for shows like "Dark Angel", "Titus", "Undeclared", "Action", "That '80s Show", "Wonderfalls", "Fastlane", "Andy Richter Controls the Universe", "Skin", "Girls Club", "Cracking Up", "The Pitts", "Firefly", "Get Real", "FreakyLinks", "Wanda at Large", "Costello", "The Lone Gunmen", "A Minute with Stan Hooper", "Normal, Ohio", "Pasadena", "Harsh Realm", "Keen Eddie", "The $treet", "The American Embassy", "Cedric the Entertainer Presents", "The Tick", "Luis", and "Greg the Bunny". Lois asks whether there is any hope, to which Peter replies that if all these shows are canceled they might have a chance; the shows were indeed canceled during "Family Guy"s hiatus.
