ABSTRACT
Television commercials are television messages designed to sell a product, service, or an idea. A public service announcement, or PSA (public service bulletin [PSB] in the United Kingdom), is similar to a commercial but is produced for a socially relevant cause or a nonprofit organization. PSAs are usually dedicated to improving or serving organizations involved in education, health, welfare, safety, and so on. In the United States, commercial television stations are required by federal communications law to provide service to the community, and airing PSAs is considered a form of community service. Stations usually use their inventory of unpurchased air time to run PSAs. There is no charge to the nonprofit organization, but the PSAs are most often scheduled to run during nonprime time periods.
