One has to wonder when Netflix decided to offer its streaming movie service on video game consoles whether it would have such a drastic effect on American internet usage.
I mean, look at this report: it states that almost 20% of total internet bandwidth usage in the United States is from people watching movies and TV shows via Netflix on their video game consoles.
That's not people watching Netflix - that figure, including PCs, stands even higher. It's just people watching stuff on a PS3, Xbox 360 or Wii. Accounting for almost 20% of total internet traffic.
If you want a breakdown, the most usage was recorded on the PS3 (with 30% of Netflix's total usage), with the Xbox 360 close behind (at 25%) and the Wii third with just over 10%.
