Why doesn't Google just buy Viacom?

I have been seriously concerned for the last 10 years or so about the amazingly out of proportion influence the media/entertainment industry has been having over the legal system here in the United States.

We have seen the collective entertainment industry having a huge amount of power as “copyright holders” that is disproportionate to their economic contributions to society overall. The information technology industry, loosely including everyone from hardware vendors to software development to web services, is vastly larger than the media and entertainment companies in terms of their economic footprint.
