Public service announcements (PSA's) are short messages intended to inform and persuade the general public. These announcements are distributed via public media, mail, and posters, or broadcast via video or audio channels to reach the largest possible audience. More recently, social media, because of it's viral nature, has become a platform for people to share PSAs in a variety of formats.
Broadcast media (radio and television) are required by the Federal Communications Commission (FCC) to serve "in the public interest," so many will donate up to a third of their commercial air time each day to airing PSAs for no charge. The people who appear in PSAs, celebrity or not, get NO paycheck.
