In Big Data: A Revolution that Will Transform How We Live, Work, and Think, Viktor Mayer-Schonberger and Kenneth Cukier write--

Internet companies have been particularly swamped [by data]. 

Google processes more than 24 petabytes of data per day, a volume that is thousands of times the quantity of all printed materials in the U.S. Library of Congress. Facebook, a company that didn't exist a decade ago, gets more than 10 million new photos uploaded every hour. Facebook members click a "like" button or leave a comment nearly three billion times per day, creating a digital trail that the company can mine to learn about users' preferences. Meanwhile, the 800 million monthly users of Google's You Tube service upload over an hour of video every second. The number of messages on Twitter grows around 200 percent a year and by 2012 had exceeded 400 million tweets a day.

Think about it.
