Watch Time Not Views: Pick the True Currency

“When users spend more of their valuable time watching YouTube videos, they must perforce be happier with those videos. It’s a virtuous circle: More satisfied viewership (watch time) begets more advertising, which incentivizes more content creators, which draws more viewership. Our true currency wasn’t views or clicks—it was watch time. The logic was undeniable. YouTube needed a new core metric.”

“In September 2011, I sent a provocative email to my boss and the YouTube leadership team. Subject line: “Watch time, and only watch time.” It was a call to rethink how we measured success: “All other things being equal, our goal is to increase [video] watch time.””
