48 hours of video are uploaded to YouTube every minute

"Back in November we challenged you to up the volume of videos you uploaded to the site. And boy, did you take the bait. Today, more than 48 hours (two days worth) of video are uploaded to the site every minute, a 37% increase over the last six months and 100% over last year. From videos documenting a baby’s first steps in San Francisco, Calif., to a protest in Syria, to a commencement speech at Yale University, we’re continually impressed and inspired by the quality and breadth (in addition to quantity) of videos that you upload to the site every day. On our end, we're constantly evolving to provide the best video sharing and viewing experience for you from faster processing of uploads to longer video lengths to the launch of self-service live stream capabilities to partners."
