A US court has ruled that Google must provide information on every YouTube user who has ever watched a video on the video-sharing Web site. The ruling comes as part of Google's battle against Viacom, which claims YouTube breaches copyrights.
The viewing log will be handed over to Viacom itself, and will include a user's ID, IP address and video clip details. The ruling also applies to users outside the United States, despite it being handed down by a US court.
Google said of the ruling: "We are disappointed the court granted Viacom's over-reaching demand for viewing history. We will ask Viacom to respect users' privacy and allow us to anonymise the logs before producing them under the court's order."
