A few weeks ago, news headlines stated that both platforms are on par now with approx. 4 bn video views daily (and recently, Snapchat said they have 4bn views daily, too). Whenever I talk about these numbers, I always mention that Facebook counts a video view when an autoplay video has been going for three seconds, and that in "minutes delivered", YouTube ought to be way ahead of Facebook. Well, now we have some numbers. I will switch to "years delivered": The world spends 46,000 years (!) every day in front of YouTube. In the US: 8,000 years streamed daily. And on Facebook? 713 years.
So that's that.
