Sponsorship underwriting refers to financial sponsorship of a venture. It is funding donated for the support of a project, program, event, initiative, activity, or even a salary. It is also used as a term within public broadcasting (both public television and radio) to describe funding given by a company or organization for the operations of the service, in exchange for a mention of their product or service within the station's programming. Generally, foundations are identified as underwriters and corporations as sponsors. Individuals can be either, but in most instances underwriters and sponsors will be foundations and corporations.
