It’s official: YouTube has a bigger audience than ever,

watching for a longer time than ever.

So said YouTube CEO Susan Wojcicki at VidCon this week. 1.4 billion people populate China, whereas YouTube has 1.5 billion logged-in viewers every month. That’s 1/5 of the entire world’s population.

Perhaps more impressively, the average viewing time for each of those viewers is 1 hour. And that’s only counting the logged-in viewers, so statistics are likely to be much higher in reality.

These figures have grown from 2011 when the average viewing time was only 1 minute. The statistical leap can be explained by mobile devices as most of those 1.5 billion views are on mobile, which wasn’t so accessible in 2011.
