A Video Library:
At present the largest Video Library on Earth is YouTube.
- YouTube has over a billion users — almost one-third of all people on the Internet — and every day people watch hundreds of millions of hours on YouTube and generate billions of views.
- YouTube overall, and even YouTube on mobile alone, reaches more 18-34 and 18-49 year-olds than any cable network in the U.S.
- Once users are on YouTube, they are spending more time per session watching videos. On mobile, the average viewing session is now more than 40 minutes.
