YouTube contributed 22 percent of total global bandwidth in the first half of 2011, up from just 17 percent in the same period of 2010, according to a new report from network management vendor Allot Communications.
The video site now accounts for 52 percent of all global mobile video streaming, Reuters reported.
Video streaming made up 39 percent of all mobile traffic, while file sharing, including both P2P file transfers and downloads from one-click host sites, followed with 29 percent, and web browsing with 25 percent.
Video streaming boosted 93 percent in the first half of 2011. VoIP and IM traffic gained even faster, at 101 percent, but they only represented a niche of all mobile traffic, at 4 percent.
Mobile data overall grew 77 percent over the past year, compared to 25 percent of fixed networks, PCMag reported.
