In British
broadcasting, the
watershed is the point in time after which
programmes with adult content may be broadcast. In the same way that a
watershed refers to the crest dividing two
drainage basins, a broadcasting watershed serves as a dividing line. It divides the day into the overnight period where family-oriented programming
suitable for children may be aired and where programming aimed at or suitable for a more adult audience is permitted, though not required. It may also mean the period of time during which programmes with
adult content may be broadcast. Examples of adult content include, but are not limited to,
graphic violence,
horror,
strong language,
nudity,
sexual intercourse,
gambling and
drug use, or references to these themes without necessarily portraying them. In most countries, the same set of rules also applies to advertisements on
radios and
television, both for the content of the commercial and the nature of the product or service being advertised.
