“PSA,” or “Public Service Announcement,” refers to a method of conveying crucial information to the public through various media channels like TV, radio, or social platforms. These messages are typically initiated by government agencies or non-profit organizations aiming to educate, inform, or promote public safety. 

PSAs cover diverse topics, ranging from weather alerts to spreading awareness about rapidly spreading diseases. The primary objective is to enhance public welfare by disseminating vital information, urging individuals to take precautions or adopt specific behaviors for their safety and well-being, and contributing to a collective effort to address societal concerns and emergencies.

Example

“ABC News made a PSA- public service announcement regarding a tornado warning next week”
