“When we started releasing data publicly, we measured it in petabytes of traffic,” said Doug Webster, a Cisco Systems market executive who is responsible for an annual report by the firm that charts changes in the Internet. “Then a couple of years ago we had to start measuring them in zettabytes, and now we’re measuring them in what we call yottabytes.” One petabyte is equivalent to one million gigabytes. A zettabyte is a million petabytes. And a yottabyte is a thousand zettabytes. The company estimates that video will account for 90 percent of all Internet traffic by 2013. (cite)
