PHILADELPHIA (CBS) — If you think kids and teens are watching more online videos these days, you’re right. A new survey from Common Sense Media finds the number of young people watching online videos every day has more than doubled — and they’re watching for an average of almost an hour.

That’s twice as long as just four years ago.

Plus, they’re often viewing videos on websites like YouTube that are supposed to be off limits to kids younger than 13.
