 Underwriting spot

An underwriting spot is an announcement made on public broadcasting outlets, especially in the United States, in exchange for funding.These spots usually mention the name of the sponsor, and can resemble traditional television advertisements in commercial broadcasting to a limited extent; however, under the terms of a public broadcaster's license from the Federal Communications Commission, such spots are prohibited from being promotional (such as making product claims, using superlatives, or being more than 30 seconds long) or making any sort of "call to action" (a phrase that refers to "any device designed to prompt an immediate response or encourage an immediate sale" such as announcing prices or providing an incentive to buy).
