Abstract: The Pew Internet & American Life Project’s first major report on online video also shows how many video viewers have contributed to the viral and social nature of online video. More than half of online video viewers (57 percent) share links to the video they find with others, and three in four (75 percent) say they receive links to watch video that others have sent to them.
