The movie delivery company's video streaming service is the largest source of peak downstream Internet traffic in the U.S., according to a new report by Sandvine. (Downstream traffic flows to the user's computer.) As you can see from the Business Insider chart, its share is way larger than Hulu and YouTube. From TechCrunch:
Video files are so big that it does not take much usage for it to take over in terms of bandwidth consumed. But these numbers definitely point to a future where video accounts for more and more of the traffic on the Internet. As recently as last November, Web video alone accounted for an estimated 37 percent of Internet traffic.
