In chapter 4, Hilliard discusses the three kinds of announcements found in broadcast and cable television and in radio:
Commercials, which sell a product or service for money
PSAs, which do not sell a product or service for money but is
made on behalf of a non-profit organization or activity and can include
advancing an idea or policy
Promos, which promote the station, channel or network itself
All three are perhaps the oldest forms of strategic communication
in video. All three also found in the world of the internet; between
game plays on apps, before streaming videos, on social media pages. In
your opinion, what differences exist between commercials, PSAs and
promos on the air and online? Whether or not there are, should there
be? If so, what? Explain your reasoning.
