Family Guy has been sued for copyright infringement due to parody songs used in episodes. For example, the owners of "When You Wish Upon a Star" sued over Family Guy using an altered version of the song in an anti-Semitic manner. Acquired programs on BBC, including Family Guy, must comply with content guidelines to ensure content is suitable for audiences and not broadcast before the watershed of 9pm. Ofcom regulates broadcasting in the UK and ensures broadcasters follow the broadcasting code by licensing services and examining complaints about potentially offensive or harmful content.
