The percentage of all adults who watch video online jumped 14 points in the past two years, from 52% of all online adults in May 2008 to 66% in May 2010. While Millennials are still the most likely generation to watch online video, as 80% have done so, other generations have seen significant growth—55% of Older Boomers have watched video, up from 30% in 2008, and one in five members of the G.I. Generation have watched videos online as well. Over the past few years, comedy video viewership has grown more than any other type of video asked about in our surveys: in 2009 half of all online adults (50%) had watched a comedy video online.
