Every country operates its own censorship system. In some countries censorship is greatly influenced by politics (China) or religion (Samoa, Saudi Arabia). Cultural and historical factors also affect how a country treats its citizens' access to all kinds of information.
In New Zealand, the Office of Film and Literature Classification can classify a huge variety of publication types. However, many countries have specialist film censorship bodies that do not deal with other types of publications. They can be government run classification bodies operating under legislation (eg New Zealand, Australia, Ireland, Singapore), or industry run classification boards (eg UK, USA ).
Some countries have virtually no restrictions on what types of films can be seen by their population, for example, France. However, nearly all countries ban films promoting the sexual exploitation of children.
