A report from Cisco indicates that nearly 800 million people watched online videos last year, and that number will nearly double by 2016. And nearly all of those people are expected to increase their use of online videos over time. In 2016, Cisco's annual Visual Networking Index predicts, 1.5 billion people will generate the equivalent of 1.2 million minutes of video traffic per second.
Online video traffic will continue to be driven through a broad range of devices, with mobile video traffic growing sixteen-fold in four years, and HD streams to TV sets increasing sixfold. HD streaming of movies and TV programs alone will account for 6% of global internet traffic.
