Public service announcement
message in the public interest, often disseminated as a free advertisement
A public service announcement (PSA) is a message in the public interest disseminated by the media without charge to raise public awareness and change behavior. Oftentimes these messages feature unsettling imagery, ideas or behaviors that are designed to startle or even scare the viewer into understanding the consequences of undergoing a particular harmful action or inaction. For example, a PSA may show imagery of drug users before and after their addiction, or realistic skits of domestic violence situations, as well as explaining the importance of avoiding such choices. In the UK, they are generally called a public information film (PIF); in Hong Kong, they are known as an announcement in the public interest (API).
History
The earliest public service announcements (in the form of moving pictures) were made before and during the Second World War years in both the UK and the US.
In the UK, amateur actor Richard Massingham set up Public Relationship Films Ltd in 1938 as a specialist agency for producing short educational films for the public. In the films, he typically played a bumbling character who was slightly more stupid than average and often explained the message of the film by demonstrating the risks if it were ignored. The films covered topics such as how to cross the road, how to prevent the spread of diseases, how to swim, and how to drive without causing the road to be unsafe for other users. During the war, he was commissioned by the UK Ministry of Information to produce films for the war effort. Massingham began to produce longer films, for both private companies and the Government, after the War.
In the US, the Ad Council (initially called the War Advertising Council) was set up in 1941, when America entered World War II. It began implementing on a massive scale the idea of using advertising to influence American society on a range of fronts.

Why this record matters
The subject matters to the general reference register because the source frames it as message in the public interest, often disseminated as a free advertisement. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 7, 2026. The linked authority identifier is Q1196567. The Library of Congress control number is sh85001190. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1938 and 1941.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
