A report from the Pew Internet & American Life Project has determined that the audience for online video-sharing sites such as YouTube and Google Video has almost doubled since 2006. About 62% of all online users now say they have watched video on these sites, compared to 33% who reported the same in December 2006.

While the increase was virtually across all demographics, Web video is now approaching total penetration among younger online users. The Pew report found that nine in 10 Web viewers aged 18 to 29 say they watch content on video-sharing sites, and more than a third in that age group (36%) say they do so every day.

Meanwhile a separate report from marketing research firm eMarketer forecasts that online video viewing will reach 70% of the U.S. Internet population this year and will extend to 85% of that same audience by 2013. In the macro view, that prediction will mean that 59% of the total U.S. population will be online video viewers in 2013, up from 47% this year.

So who’s helping you leverage video to get your brand in front of this growing audience?
