Television content rating systems give viewers an idea of the suitability of a television program for children or adults. Many countries have their own television rating system and each country's rating process may differ due to local priorities. Programs are rated by either the organization that manages the system, the broadcaster or by the content producers themselves.
A rating is usually set for each individual episode of a television series.
The rating can change per episode, network, rerun and per country. As such it is impossible to state what kind of rating a program has, without stating when and where this rating applied.
