Facebook believes video content is the key to the company’s future, that much has already been made clear, but now it has the numbers to back that up. In its most recent earnings call, the company revealed that the videos on its social network pull in more than four billion views every day, around 75% of which comes from mobile devices. Considering how videos on Facebook play automatically, those numbers are a bit inflated, but that doesn’t take away from the fact that Facebook is actually becoming a serious YouTube competitor.
