I want to know the answer to the following question:
How many unauthorized clips did Viacom allegedly find on youtube that infringed its copyrights?
All the background I'm provided with is that "Viacom, demanding $1 billion in damages, said that it had found more than 150,000 unauthorized clips of its material on YouTube that had been viewed "an astounding 1.5 billion times".". Is that enough to answer the question?
Answer: yes
