A report commissioned by NBCUniversal has concluded that nearly a quarter of all Internet traffic infringes on copyrights, with the open source file sharing application BitTorrent accounting for nearly half of the infringing content.
Conducted by Internet intelligence company Envisional, the 56-page report claims to be the first such study to comprehensively estimate the amount of Internet traffic that infringes on copyrighted material.
The study excluded pornography because it is difficult to determine its copyright status.
The report estimates that about two-thirds of BitTorrent traffic is illegitimately shared content such as films, music, computer games and software.
In a statement online, BitTorrent, Inc. asserts that it merely provides technology for others to use.
"We understand that some people may use some of our technologies in ways that represent a risk to certain copyright holders, but certainly no more so than other technologies," wrote Shahi Ghanem, chief strategist at BitTorrent, Inc.
