More than nine-in-ten journalists in the United States use social media for their jobs, according to a recent Pew Research Center survey of reporters, editors and others working in the news industry. But the sites that journalists use most frequently differ from those that the public turns to for news. Among journalists, Twitter clearly ranks at the top of the list for work-related tasks. Around 69% of U.S. journalists say it is the social media site they use most or second most for their job. Twitter is followed by Facebook at 52%. A different lineup emerges for the public. Among Americans overall, Facebook is the most widely used social media site for news, with 31% of U.S. adults saying they go there regularly for news. YouTube is the second-most frequently used site, with 22% of the public regularly getting news there.
