On March 13, 2007, Viacom filed a lawsuit against YouTube and its corporate parent Google for copyright infringement seeking more than \$1 billion in damages. The complaint was filed in the U.S. District Court for the Southern District of New York. Viacom claims the popular video-sharing site was engaging in "massive intentional copyright infringement" for making available a contended 160,000 unauthorized clips of Viacom's entertainment programming. Google lawyers say they are relying on the 1998 Digital Millennium Copyright Act to shield them from liability.[6]

On June 23, 2010, U.S. District Judge Louis Stanton granted summary judgment in favor of YouTube.[7] The court held that YouTube is protected by the safe harbor of the DMCA. Viacom has said that it will appeal before the U.S. Court of Appeals for the Second Circuit as soon as possible. [8]
