Demonstrators parade with posters in fro

WASHINGTON, UNITED STATES: Demonstrators parade with posters in front of the US Supreme Court in Washington, DC 29 March, 2005 as the nine justices heard oral arguments on the legality of file-sharing networks. The case seeks to determine whether companies that distribute peer-to-peer (P2P) software can be held liable for copyright infringement, if the networks are used for illegal copying of songs, movies, software and other content. Activists on both sides of the issue demonstrated outside the court. The Betamax legal standard, set 21 years ago and referring to a case involving the Sony Betamax video recorder, upheld the use of technology that could be used both legally and illegally. If overturned, every business involved in new technology would be subject to litigation. AFP PHOTO NICHOLAS KAMM (Photo credit should read NICHOLAS KAMM/AFP via Getty Images)
