Facebook products have a tendency to grow, and grow quickly. Video doesn't appear to be an exception.
The social network announced on its Q1 earnings call Wednesday that it now serves up four billion video views to its user base every single day, up from three billion in January and just one billion back in September.
Of those four billion views, 75 percent come from mobile devices, according to COO Sheryl Sandberg.
Facebook videos play automatically, which certainly helps to juice the total-views metric, but going from one billion to four billion total views per day in a little over six months is one of the reasons people now consider Facebook as a bona fide YouTube competitor.
What's still missing from that competition is a video ad push from Facebook that's likely on the horizon.
"We've always believed that the format of our ads should follow the format of what consumers are doing on Facebook," Sandberg added on the investors call. "The fact that there's so much consumer video, that gives us the opportunity to do more marketing video as well."
