*A video is defined as any streamed segment of audiovisual content, including both progressive downloads and live streams. For long-form, segmented content, (e.g. television episodes with ad pods in the middle) each segment of the content is counted as a distinct video stream. Video views are inclusive of both user-initiated and auto-played videos that are viewed for longer than 3 seconds.
**Facebook’s December 2013 online video viewership, particularly the number of video views, is substantially higher than prior months due to both organic and inorganic factors. The largest (and inorganic) source of increase is the recent inclusion, following a technical validation effort, of a significant volume of short (typically 6-second) Vine videos that have been uploaded to Facebook. The other, and currently less significant, factor is the limited roll-out in December of auto-play videos in the Facebook News Feed.
