In May 2011 video streaming company Netflix, headquartered in Los Gatos, California, was the largest source of Internet traffic in North America, accounting for 29.7 percent of peak downstream traffic. The company was also the largest overall source of Internet traffic.
"Currently, real-time entertainment applications consume 49.2 percent of peak aggregate traffic - up from 29.5 percent in 2009. And the company forecasts that the category will account for as much as 60 percent of peak aggregate traffic by the end of this year.
"And in Europe, the figure's even higher. Overall, individual subscribers in Europe consume twice the amount of data as North Americans" (http://www.tgdaily.com/games-and-entertainment-features/56015-netflix-becomes-biggest-source-of-internet-traffic, accessed 05-18-2011).
