THE FINDINGS: A new study from Pew Research Center's Project for Excellence in Journalism has found that YouTube has become a major platform for news.
HOW IT'S USED: Viewers turn to it for eyewitness videos in times of major events and natural disasters.
PERSPECTIVE: Viewership for TV news still easily outpaces those consuming news on YouTube, but the video-sharing site is a growing digital environment where professional journalism mingles with citizen content.
