More than one-third of all PCs worldwide now have LimeWire installed, according to data jointly released by Digital Music News and media tracking specialist BigChampagne. The discovery is part of a steady ascent for LimeWire, easily the front-running P2P application and the target of a multi-year RIAA lawsuit. For the third quarter of this year, LimeWire was found on 36.4% of all PCs, a figure gleaned from a global canvass of roughly 1.66 million desktops.
