Why? Doesn't that seem a little arbitrary? Streaming video just happens to utilize a lot of bandwidth. If the state of things were such that current netflix activity only utilized 5% instead of 50%, people would still be watching the same amount of netflix, but the statistic wouldn't seem as effective for comparison to a dystopia.

Further, netflix watchers are almost entirely composed of former/would-be TV watchers who ultimately end up spending less time in front of the tube because they avoid commercials entirely (adding up to a ton of time in aggregate) as well as at their leisure instead of when the TV guide demands they stop what they're doing to catch their show.
