Chicago, IL, Mar. 30 (UPI) -- Hollywood during the 1980s worried that videocassette recorders would savage the movie business, furnishing fans with free access to films copied from rental tapes from video stores. The industry was so worried, in fact, that it took the case all the way to the U.S. Supreme Court, in Sony vs. Betamax, hoping to protect its intellectual property rights. Two decades later, the entertainment industry is back in court, arguing this time that Internet file sharing of music and movies is illegally gnawing away at its profits -- like Godzilla gobbled up Tokyo. Last time, the justices ruled for the VCRs, but experts told UPI's The Web they are unsure who will win the battle over file sharing."There were protesters with placards, chanting in front of the court," said Daniel Fisher, an intellectual-property lawyer with Millen, White, Zelano & Branigan in Arlington, Va. "That was surprising; that was a lot of excitement. Usually, intellectual-property cases are more mundane, but this is about the future of the industry. There was one sign that said, 'Save a musician, download legally!'" By Gene Koprowski
