It's a little different as Internet makes it far easier to target a user compared to classic means of propaganda especially excaberating the issue of identifying real news vs "fake" news. With TV and Newspaper there are less "anonymous" outlets for content and a system of oversight could be applied in theory. A WhatsApp forward or an FB post spreads like a virus with no clear source. It's trivial to spread lies and for a user to consume it.
Unless you are the ones writing a news story you have no idea who made it or what influenced it.
