In censorship debates, the term means cultural works (including art, literature, films, television and music) that are considered appropriate for children. Frequently, the term " Think of the children" is used during a moral panic to censor new forms of media. Often, depiction of nudity, sex, horror, profanity, racial slurs, innuendo, drug use, blasphemy and racism are declared to be worthy of censorship. Many parents disagree over the ages at which children should be exposed to certain forms of media. The precise definition of "family friendly" can vary depending upon the perceived acceptability of content for children - one of the most challenged books in United States libraries is Captain Underpants, a book that contains toilet humor that parents read out to children - frequently parents that complain about media that contains profanity attempt to deny other families the ability to choose what is appropriate for their children. The values of the individual family, such as their belief in religion, can also impact whether the family perceives a product as family-friendly.
Frequently, family friendly products avoid marketing solely to children and attempt to make the product palatable to adults as well.
