Big data is here - and no one knows big data better than Google. It has access to several planets worth of information that is constantly up to date - as people continue interacting with Google's services.
Proving this point, google recently released a white paper arguing that it had the ability to predict blockbuster movie success.
"70 percent of the variation in box office performance can be explained with movie-related search volume (such as trailers)."
Thats pretty cool. That means - if you want to know if a hollywood movie will be a success - just google search the answer (or at least see what the google-searching public has been up to). If your movie happens to be trending in advance of your release date - odds are that odds are in your favor.
I hope you know by now - google has been spying on you. From your youtube views, to the content of your gmail emails - google has been painstakingly going through every word to get to know you better (just like a good neighbor).

If you are logged into your google account that link should send you to a fun little page. Here you can view what google thinks of you - specifically who you are and what you like to search.
So the argument returns, yes the government is beefing up its online presence big time - but should google really know more about you than your government? Would you rather a private corporation hold your detailed information or a public one?
