A US judge dismissed for the second time a billion-dollar lawsuit by entertainment giant Viacom accusing Google-owned website YouTube of knowingly profiting from pirated video clips. US District Court Judge Louis Stanton firmly stood by his original decision in the case after being instructed by an appellate court to take another look. "There is no evidence YouTube induced its users to submit infringing videos, provided users with detailed instructions about what content to upload or edited their content, prescreened submissions for quality, steered users to infringing videos or otherwise interacted with infringing users to a point where it might be said to have participated in their infringing activity," Stanton said in his ruling. Viacom sued Google and YouTube in March 2007, arguing that they condoned pirated video clips at the website to boost its popularity. The lawsuit was merged with a similar complaint being pursued by the English Premier League, which said football clips were also routinely posted on YouTube without authorization. Viacom's suit charged that YouTube was a willing accomplice to "massive copyright infringement" and sought more than one billion dollars in damages. The suit was dismissed in June 2010 by Stanton on the grounds that YouTube was protected against Viacom's claims by provisions of the Digital Millennium Copyright Act. The 1998 law protects Internet firms from copyright violations by their users, and the judge ruled that YouTube's actions, such as quickly removing infringing videos when requested, were in line with the measure. Viacom's film and television empire includes many youth-oriented networks like MTV and VH1, popular comedy shows such as Jon Stewart's "The Daily Show" and the Paramount movie studio. YouTube was a year-old Internet sensation when Google bought it in a $1.65 billion stock deal in 2006. The Viacom copyright case was closely watched at the time as film and television studios grappled with adapting to the ease with which digital content could be shared on the Internet. Online streaming of shows and movies has since become common, with creators finding new sources of revenue from online delivery, including through alliances with services such as Netflix, Hulu, YouTube and Xbox Live. An appellate court directed Stanton last year to hear renewed arguments on key aspects of the suit. He dismissed the case in response to a motion by Google for a summary judgment.
