This isn’t a good thing, at all. I don’t think it’s just teens either. Advertising has become so prevalent on the web, and so embedded, that the difference between actual “news” and an ad is pretty blurred. That means that savvy marketers could influence public opinion with stories that seem to be news, but truly aren’t.
I mean really, people already like and share things on social media that aren’t remotely true, how much of a stretch is it to think they would see an ad and assume it’s journalism?
