So says a new report from social media research consultancy Trendstream and research firm Lightspeed. From story at MediaPost.com:

“In one week in January, 97 million Americans viewed a streaming clip online — as many as are tuning into any major broadcast network — according to a recent survey of 1,000 U.S. active Web users ages 16-65. What’s more, with 72% of U.S. Web users watching clips online, Web video outstrips both blogging and social networking, and is now the leading “social-media platform.”

The “broadcast mode is dead,” said Tom Smith, managing director of Trendstream. “Now is the time for co-creation, user distribution and a true democratization of video content.”

And the new video-ready iPhone will just accelerate this trend. (via @malloryglosier)
