Google's YouTube woes are nowhere near the end, with piracy still a major issue. It has cost them media deals and brought them to court. Now, Viacom will be suing Google and YouTube, citing rampant piracy of content they own on their various TV channels. Adding a bit of salt to the wound, they are calling the piracy "intentional", and are asking for an injunction to prevent further use of YouTube:

"After a great deal of unproductive negotiation, and remedial efforts by ourselves and other copyright holders, YouTube continues in its unlawful business model. Therefore, we must turn to the courts to prevent Google and YouTube from continuing to steal value from artists and to obtain compensation for the significant damage they have caused."
Viacom and Google have been in discussions for a while, and many videos have already been removed. Apparently not enough for Viacoms liking. Google has not yet commented on the lawsuit.
