I want to know the answer to the following question:
How many CDs had been distrubuted around the world by 2007?
All the background I'm provided with is that "CDs are increasingly being replaced by other forms of digital storage and distribution, with the result that audio CD sales rates in the U.S. have dropped about 50% from their peak; however, they remain one of the primary distribution methods for the music industry.". Is that enough to answer the question?
Answer: no
