From USA Today:
One in five online Americans view video over the Internet on any given day, thanks to speedier Internet connections and a wider selection of clips, a study finds.
Young adults watch in greater numbers and often turn to humorous clips, while all other age groups use video predominantly for news, according to the Pew Internet and American Life Project.
On a typical day, 19% of U.S. Internet adults watch some form of video. News ranked first and comedy second overall.
