However these documents seem to refer to the situation in North America, who has Netflix, Hulu, Youtube, and is back in 2009. Apparently after the Megavideo debacle in 2011, there was a significant drop of traffic towards video streaming services. It is difficult to get information about internet usage per continent/countries. Europe: Netflix and Hulu are not available. Netflix actually just came to the UK. They make a large chunk of the US traffic. Youtube is heavily throttled in France. From studies done by Orange, P2P still seems the dominant usage. China: P2P live streaming appears to be massively used. Japan, India, South America: i have little information -- _Ivan Chollet_
