A new survey of 50 randomly sampled radio PSA directors in the top-50 markets, finds that 100% of stations surveyed have public service announcement rotation, with 78% having between one and ten PSA slots to fill in a typical week. Thirty percent of stations now use MP3s exclusively for the PSA content, with 46% still requesting CDs. Twenty-four percent of stations use exclusively copy and have their local on-air talent voice the PSAs.

Public service announcements (PSAs) are produced audio reports or written scripts, generally running :15, :30 and :45 in length that are generated for on-air use by radio stations and/or networks to promote a specific social message aimed at increasing public awareness or having listeners take action about a particular issue. Through PSAs, organizations can build and increase their image and stations can provide important information regarding compelling social issues to their audiences. Fifty randomly sampled stations in the top-50 markets were interviewed in August of 2004.

In 1996, the FCC dropped the licensing requirement that each station should provide substantial evidence of public service as a requirement of renewal. Despite the fact that stations are now not required to prove how they serve the public good, many, if not most stations, still provide public service content to their listeners on a regular basis. In fact, 100% of the stations surveyed said that to make it into rotation, a public service announcement must address an issue that is prevalent in their local community.
