The document outlines the roles and legal powers of various regulatory bodies in managing advertisements and media content, including the ASA, BBFC, PEGI, and Ofcom. The ASA oversees advertising standards but lacks legal enforcement powers, while the BBFC is responsible for film classification with some legal authority for seizure of illegal media. PEGI helps consumers make informed decisions about video games, and Ofcom has broad powers to protect interests across telecoms and broadcasting sectors.
