Google has won a landmark ruling as a judge threw out a $1bn lawsuit brought by Viacom accusing the internet giant of allowing copyrighted material on its YouTube service without permission.
Viacom had accused Google of “massive intentional copyright infringement”.
But the Manhattan judge said Google and YouTube could not be held liable merely for having a “general awareness” that videos might be posted illegally.
Media conglomerate Viacom said it planned to appeal against the decision.
Google called the ruling “an important victory”.
