On Monday, broadband services company Sandvine released data showing how video streaming utterly dominates the internet. During peak hours in North America, 70% of all bandwidth going from providers to consumers (that's "downstream" bandwidth) was taken up by video.
Netflix is the biggest bandwidth hog of the bunch, making up more than 37% of all downstream traffic during peak hours. Google's YouTube is a distant second, with about 18%. All non-video web services combined (HTTP) take up only 6% of all downstream bandwidth.
