In case you’re not aware of it, Pew Research has found that a third of Americans rely on Facebook as a primary news source and more than half rely on it at least part of the time. To me that just proves that P. T. Barnum was right.
To be more charitable I think that’s to be expected with the collapse of local reporting. Today newspaper newsrooms employ just about half as many people as they did just 20 years ago and a lot of that decline is in local dailies. Nowadays if you’re looking for local news you may have little choice other than to turn to Facebook.
IMO it also explains the decline in readership of supermarket tabloids. Why check out the National Enquirer for news when you can get the same fake news on Facebook and people won’t look at you funny in the supermarket checkout line for reading it?
