“Fully 71% of online Americans use video-sharing sites such as YouTube and Vimeo, up from 66% a year earlier. The use of video-sharing sites on any given day also jumped five percentage points, from 23% of online Americans in May 2010 to 28% in May 2011.”

Pew Internet (2011)

This is a trend I’ve also noticed amongst my friends over the past year, largely driven by more of them using smartphones and iPads, which make sharing and watching video a whole lot easier.
