A commercial advertisement on television is a span of television programming produced and paid for by an organization, which conveys a message, typically to market a product or service.
Advertising revenue provides a significant portion of the funding for most privately owned television networks. The vast majority of television advertisements today consist of brief advertising spots, ranging in length from a few seconds to several minutes.
Advertisements of this sort have been used to promote a wide variety of goods, services and ideas since the dawn of television.
