According to Yahoo! News, “Rupert Murdoch’s Fox News Channel threatened to sue the makers of The Simpsonsover a parody of the channel’s right-wing political stance, the creator of the hit US television show has claimed. According to [Matt] Groening, Fox took exception toward a Simpsons’ version of the Fox News rolling news ticker which parodied the channel’s anti-Democrat stance, with headlines like ‘Do Democrats Cause Cancer?’ While the lawsuit never materialized, Groening said some action was taken. ‘Now Fox has a new rule that we can’t do those little fake news crawls on the bottom of the screen in a cartoon because it might confuse the viewers into thinking it’s real news,’ he said.”
