Viacom Inc is appealing a U.S. judge's dismissal of its $1 billion lawsuit accusing Google Inc. of allowing copyrighted videos on YouTube without permission, reports Reuters. Viacom claimed tens of
thousands of videos on Google's video service YouTube were posted based on its copyrighted works and that the Internet company knew about it, but did not stop illegal uploads. The 3-year-old lawsuit
was seen as a test of the Digital Millennium Copywright Act, making it a crime to produce technology to circumvent anti-piracy measures and limiting liability of online service providers for copyright
infringement by users. Viacom owns cable networks such as MTV and Comedy Central and the Paramount movie studio.
