“Nearly 72 hours of video are uploaded to YouTube, three million pieces of content shared by Facebook users, and 230,000 new photos posted on Instagram—every minute. More than 90 million websites are built every year. And perhaps the most sobering statistic: five exabytes (or 5 billion billion bytes) of data could store all the words ever spoken by humans between the birth of the world and 2003. In 2011, five exabytes of content were created every two days.”
