Viacom agrees to YouTube privacy deal
From Information World Review:
Google and Viacom have reached an agreement to omit user information from a YouTube log which the search giant has been forced to hand over.The agreement means that Viacom will not be able to see precisely which videos have been accessed by each viewer, nor will it be able to see a specific user's viewing history.
Additionally, all users' IP addresses and visitor ID information will be removed from the list.
