The study reveals that mobile data usage has skyrocketed from an average of 237 Petabytes per month in 2010 to 597 Petabytes (0.6 Exabytes) by the end of 2011 and it is now predicted to hit 10.8 Exabytes by 2016. Mobile video traffic (e.g. Netflix, YouTube etc.) continues to be the primary cause, accounting for 52% of all mobile data usage by the end of 2011 (up from 49.8% in 2010), and it could exceed 70% by 2016."
