Sometime in early January my roommate (also a Facebook engineer) and I were talking late at night in the office and shared a realization: we both had tons of videos we had taken with our phones and digital cameras, and had nowhere to put them. Of course, plenty of video sharing sites already existed, but none provided useful distribution to our friends (like Facebook's Photos application). Now that consumer mobile phones and digital cameras are perfectly capable of taking good quality video, we knew that it was time to build a video application on top of the social graph.
