According to Sandvine, even when averaged over the entire day, Netflix accounted for 22.2 percent of North American data traffic. That’s more than even more than BitTorrent, which accounted for 21.6 percent of traffic, and had long been the single largest component of data traffic on broadband networks. One could argue that’s good news for Hollywood studios, which have spent the last several years trying to combat the spread of their movies on peer-to-peer networks like BitTorrent.
I've always believed that if you make content easy to access and price it reasonably the majority of people will pay for music, movies, ebooks, etc. There will always be pirates, but Netflix is proving that most people will pay for content if it's a fair deal.
