Survey: Number of kids watching online videos soars

A new survey shows the number of young Americans watching online videos every day has more than doubled. They're glued to them for nearly an hour a day, twice as long as they were four years ago.

And often, the survey found, they're seeing the videos on services such as YouTube that are supposedly off limits to children younger than age 13.

Common Sense Media is the nonprofit organization that issued the report. The group tracks young people's tech habits and offers guidance for parents.

The survey of American youth included the responses of 1,677 young people, ages 8 to 18. Among other things, it found that 56% of 8- to 12-year-olds and 69% of 13- to 18-year-olds watch online videos every day. In 2015, the last time the survey was conducted, those figures were 24% and 34%, respectively. The margin of error was plus or minus 2.8 percentage points.
