A television advertisement (also called a television commercial, commercial, advert, TV advert or simply an ad) is a span of television programming produced and paid for by an organization. It conveys a message promoting, and aiming to market, a product or service. Advertisers and marketers may refer to television commercials as TVCs.
Advertising revenue provides a significant portion of the funding for most privately-owned television networks. During the 2010s, the number of commercials has grown steadily, though the length of each commercial has diminished. Advertisements of this type have promoted a wide variety of goods, services, and ideas ever since the early days of the history of television.
