or all the video people watch on the web, it is still a tiny fraction of how much they watch on TV in terms of time spent. In a report put out yesterday on the State of the Media summarizing 2011 data, Nielsen estimates Americans spend an average of 32 hours and 47 minutes a week watching traditional TV. They only spend an average of 3 hours and 58 minutes a week on the Internet, and only 27 minutes a week watching video online. All those billions of videos watched online still only represent 1.4 percent of the time spent watching traditional TV.

Even on the web, there is a huge difference between the video sites which attract the biggest audiences and those which are the most engaging. The top 5 video sites by unique visitors are YouTube, Vevo, Yahoo, Facebook, and MSN. But the top 5 video sites by time spent are Netflix, YouTube, Tudou, Hulu, and Megavideo.

A broad consortium of TV station groups have banded together for what may be the most ambitious effort yet to establish a dominant brand in the sprawling social-TV space.
