A PSA, or Public Service Announcement, is a message created to inform or educate the public about important issues. These announcements often focus on health, safety, or social concerns, aiming to raise awareness and encourage positive behavior. PSAs can be found in various formats, including television, radio, print, and online media. Typically produced by government agencies, non-profit organizations, or community groups, PSAs are designed to reach a wide audience. They often address topics such as smoking cessation, disease prevention, or environmental protection, helping to promote community well-being and informed decision-making.
