LimeWire was a peer-to-peer file sharing (P2P) platform that launched with its own client in 2000. LimeWire utilized the gnutella network and BitTorrent protocol to allow users share content by uploading and downloading content through the client. LimeWire offered both a free version and a paid enhanced version called LimeWire Pro, which, somewhat ironically, could be acquired through the regular LimeWire software as paid users shared their copies of Pro with the platform. LimeWire had a solid ten-year run before a lawsuit back by music industry heavyweights resulted in the company, and it's software client, being shut down in 2010.
