There's nothing surprising in the results of a 2016 study conducted for Buzzfeed by Echelon Insights and Hart Research. It shows that the majority of Americans who were likely voters in 2016 were under the age of 50, and that about half of them share news links on social media every week. But the results of this study conform with a growing body of other research that shows a massive shift in how people discover news, and how trust works in a media system increasingly dominated by social media platforms.
