I actually gained some knowledge as of reading that piece because I did PSA videos in the past and it was close to a minute or two long. I did not know there had to be a cap for PSA videos. Also I thought it was an awareness type of deal, but a PSA video is actually counted as an advertisement. My favorite part was the introduction, the way it was structured where you had a "A" and a "B" option. After reading the whole PDF document, I have a clear understanding of what PSA is.
