It is estimated that by 2018 a million minutes of video will be transmitted across the Internet every second.
Cisco, a leading manufacturer of hardware that connects the Internet, estimates that global internet traffic will reach 131 exabytes of data per month within 5 years.
Even by the end of 2013 video was responsible for 66% of all data. By 2018 this is likely to be 79%.
All of the words ever spoken by humans is estimated to equal about 5 exabytes of data (The University of California, Berkeley). With over 26 times that amount being transferred every month, it truly is a massive amount of data.
