Grokster Lt. was a privately owned software company based in Nevis, West Indies that created the Grokster P2P file-sharing client in 2001 that utilized the FastTrack protocol. Grokster Ltd. was rendered extinct by the United States Supreme Court's decision in MGM Studios, Inc. v. Grokster, Ltd. The court ruled against Grokster's peer-to-peer file sharing program for computers running the Microsoft Windows operating system, effectively forcing the company to cease operations. The product was similar in look and feel to Kazaa which is marketed by Sharman Networks.
