Katerina Matsa: About two-thirds of U.S. adults (68%) get news on social media sites... Facebook is still far and away the site Americans most commonly use for news, with little change since 2017. About four-in-ten Americans (43%) get news on Facebook. The next most commonly used site for news is YouTube, with 21% getting news there, followed by Twitter at 12%. Smaller portions of Americans (8% or fewer) get news from other social networks like Instagram, LinkedIn or Snapchat. wordsmith.social/protestation/…
