A latest research released from Pew Research Center shows that more online U.S. adults reported watching videos on video-sharing sites.
As of May 2011, 71 percent of adult Internet users in the U.S. reported using video-sharing sites. This is up from 66 percent from the year prior, and is an increase of 38 percent from five years ago.
Video-sharing sites are particularly popular among parents. More than 80 percent of parents in the survey reported visiting these sites, compared with just over 60 percent of non-parents.
The research indicates that the rise in use of video-sharing sites is at least partly being led by the growth in content on sites like YouTube and by user contributions.
Latest statistics from YouTube show that 48 hours of content are uploaded every minute to the site.
