I agree with Will76.
What was also interesting though was the fact Viacom was putting up massive amounts of videos in a slightly less than perfect quality(to emulate home user submits) under different user accounts as it noticed the amount of traffic YouTube was producing and saw it as good PR for its programs at the same time complaining of copywrite theft.
Apparantly Viacom put up so much content itself it got to a point that even they couldnt tell what items they had or had not uploaded ....
I think this case is showing a lot of interesting tactics/pr/game plans that exsist in marketing......a lot more info will come out over the next few months im sure.
