After 4 years of debate between the popular file sharing service LimeWire and the RIAA, LimeWire has been officially shut down by Judge Kimba Wood for its sharing of unauthorized copyright material. Wood ruled that the company behind LimeWire did not take appropriate steps to prevent its users from committing mass copyright infringement. The question posed now is where LimeWire's 50 million different monthly users will turn to share and download files.
