In 2008 alone, IDC says the world created 487 billion gigabytes of information, up 73% from 2007. That was 3% more than it forecast at the beginning of the year.

Not everything has to be stored. Phone call routing information, digital TV signals and spam don’t need to be saved. But a lot of information does.
