What is a Public Service Announcement?  (If you don't know what it is, Google it.)
In your own words, now tell me what it is?  What are they used for?  Can you recall an example of a PSA (or PSA's) you've seen before?  Is there a specific PSA that made a huge impact on you?

It is when an announcement is made and it raises awareness about the topic's issue so we can stop people from doing whatever they are doing. It can be a video or an article. We use them so we can change attitudes and behavior towards an issue. I can recall three examples: Drunk driving, Texting and driving, and bullying. I think the one that made the biggest impact on me would have to be Texting and Driving.
