A Case Study of an example of Fake News - inaccurate information going viral and wielding enormous influence over actual events:
"Eric Tucker, a 35-year-old co-founder of a marketing company in Austin, Tex., had just about 40 Twitter followers. But his recent tweet about paid protesters being bused to demonstrations against President-elect Donald J. Trump fueled a nationwide conspiracy theory — one that Mr. Trump joined in promoting.
Mr. Tucker's post was shared at least 16,000 times on Twitter and more than 350,000 times on Facebook. The problem is that Mr. Tucker got it wrong. There were no such buses packed with paid protesters.
But that didn't matter."
