The latest Global Internet Phenomena Report from Sandvine details how much downstream bandwidth popular video streaming services use in proportion to the entirety of the internet. The first interesting statistic is that Netflix uses 15% of the downstream bandwidth in the world and 19.1% in the USA. Amazon Prime Video actually uses more downstream bandwidth than YouTube, and the worldwide usage to stream video is 57.7% of the overall downstream bandwidth used. Netflix remains the 800-pound gorilla of the streaming world: Video from the service consumes a significant 15% of all internet bandwidth globally, the most of any single application. That's according to the latest Global Internet Phenomena Report from Sandvine, a vendor of bandwidth-management systems. Netflix was followed by HTTP media streams, representing 13.1% of all downstream traffic; YouTube (11.4%); web browsing (7.8%); and MPEG transport streams (4.4%).
