In 2017, the amount of Internet traffic generated by YouTube alone is greater than the amount of traffic on the entire Internet in 2000. Because of video streaming and the explosion in mobile devices demanding high-bandwidth applications, Internet traffic has increased over 500% since 2010 and is predicted to nearly triple by 2021 (see Figure 3.18). Internet video is now a majority of Internet traffic and will reach 82% by 2021, according to Cisco. Mobile platform traffic is expected to grow sevenfold from its 2016 levels by 2021. Cisco estimates that annual global Internet traffic will be around 3.3 zettabytes in 2021: that’s 3,300 exabytes, or, in other words, 33 with 19 zeroes behind it!
