There is a important legal battle between Viacom and Youtube (which is owned by Google). The federal judge ordered Google to release information of all Youtube users to Viacom: their IP addresses and details of videos watched by them. What are your opinions on this?
Viacom claims that Youtube has about 150,000 videos that are posted on the site without their permission, saying that it is "massive intentional copyright infringement." The lawsuit was filed in March of 2007.
