Big Purchase- worth or not?

Today's big news is that Google bought YouTube with the price of 1.65 billion dollars. Ah-ha! Big Deal, right? Last week we just heard thery were in talks. Today they are done. What does Google buy? The audience, the thousands of videos online, or a litany of copytight infringement. Time will tell. Each business has to take risk and chance as well.
There is an aphorism "Winners take all." That's reality. Clearly to say, that's the way the society runs. From Wal-Mart to Starbucks, they all hit mom-and-pop stores, even killed. No matter what they treat their employees bad or not, they are the part of globalization. I am not saying that is bad, ironically, it is the fact.
Remember "The Long Tail", it shows that diverse market makes money. Therefore, not only do we focus on pop music but also the unique music. I am still observing what kind of pattern will exist in the We the media era?
