Popular culture
Popular culture does not follow any one system of ideas, customs, philosophy, religion, or morality. Some of its forms include grammar, language, or pictures that are not accepted under a society's customs. For this reason a society or government may not approve of popular culture. If a government thinks that any form of it may harm people or cause society to change in a bad way, the government may ban it. This practice is known as censorship. In some countries popular culture is protected under freedom of speech or other rights.
