What Does Grokster Mean?Grokster was a peer-to-peer file sharing client software created by Grokster Ltd. Based on FastTrack, a popular file-sharing protocoal, Grokster was considered to be a second generation of peer-to-peer file sharing software. It was designed in such a way that it allowed users to transmit files without the going through a central server. Any files, including copyrighted files, could be transmitted.
In 2005, the United States Supreme Court rules against Grokster in a suit filed by MGM Studios, a ruling that essentially made Grokster's brand of file sharing illegal. Grokster shut down operations as a result.
