Facebook and Twitter are increasingly influential sources of news for their users, according to a survey conducted by the US-based Pew Research Center. Its study of more than 2,000 Americans found that for both social networks, 63% of users surveyed said they were getting news there – up from 52% for Twitter and 47% for Facebook in 2013. With 66% of US adults currently using Facebook and 17% using Twitter, that indicates that one in 10 Americans are getting news from Twitter, while four in 10 are getting it from Facebook.
