According to the most recent annual Visual Networking Index (VNI) Forecast released by Cisco on Wednesday, 80% of global Internet consumption will be in the form of online video by 2019, with that figure to approach the 85% mark in the U.S. 
 
Wednesday’s VNI Forecast is the tenth to be issued by Cisco and is based upon analyst assessments, real-world mobile data usage studies and Cisco’s own estimates.  The study projects that global Internet protocol (IP) traffic will triple between 2014 and 2019, at which time total global web transmissions will exceed 2 zettabytes (2 billion terabytes) per year.  Noting that “it took 32 years . . . to generate the first zettabyte of IP traffic annually,” the VNI Forecast cites global gains in Internet users, the proliferation of machine-to-machine connections that drive the “Internet of Things,” and the adoption of advanced video service applications in estimating that it “will take only three additional years to reach the next zettabyte milestone.”  Anticipating that global IP traffic will reach 168 exabytes (168 million terabytes) per month by 2019, Cisco’s VNI Forecast proclaims that nearly as much traffic will travel across global IP networks during that year than in all previous “Internet years” combined.
