Ofcom has statutory duties to ensure under-18s are protected and generally accepted standards are enforced for music videos. Key rules require appropriate scheduling of videos according to their nature and audience. Sexual or offensive content must be justified by context. Before the watershed, videos cannot contain explicit sexual images or prolonged shots, nudity, or sexualized dancing. Violent content must also be limited and not imitable by children. Lyrics focusing clearly on sex are unsuitable, as is any combination that raises the sexual nature. Ofcom provides guidance but does not prohibit all themes, relying on careful presentation according to each video's context.
