Techradar reports that the Netflix video streaming service is not the biggest user of bandwidth in North America, accounting for 22% of total internet use. These figures come from the recent Global Internet Phenomena Report (18 page pdf) by Sandvine Broadband Network Solutions. At peak periods, Netflix accounted for 29.7% of bandwidth use. If you add in other forms of "real-time entertainment" - sites providing on-demand streaming - they account for almost half of bandwidth use. The report includes data on bandwidth use in Europe and Latin America, as well as an analysis of how the Royal Wedding on April 29, 2011, affected internet use worldwide.
