Regulatory bodies like the BBFC provide age ratings for films and television content in order to protect vulnerable groups. The BBFC uses a rating system of U, PG, 12A, 12, 15, and 18 to indicate the appropriate audience for different types of content that may contain issues like sex, drugs, violence or abuse. There is debate around whether creative works should be regulated to shield children and others or if regulation goes too far in limiting artistic freedom as a "nanny state".
