Answer by spotlite28
PSAs are free public announcements. Like the “The more you know..” spots on NBC. They usually deal with little bits of information like how much energy is saved when you just remember to turn off the computer.
News Stories are (Supposed to be) factual accounts of the events of the day. Information about the mayor’s speech, the findings in an arson investigation, the red cross blood drive. They tell you what happened and why most of the time.
Advertising is paid for. Commercials for Burger King or a furniture store. They’re commercials about products and services that you can buy.
Lots of stations also run promotions about things on their channel: their news, prime time TV programs and the like.
