161,000,000,000,000,000,000 Bytes (IDC)

According to market research firm IDC, the world generated 161 billion gigabytes -- 161 exabytes -- of digital information last year. (via New York Times). Wow.

That's like 12 stacks of books that each reach from the Earth to the sun. Or you might think of it as 3 million times the information in all the books ever written, according to IDC.

I'm not sure even how many zeros that number has, I hope my title is correct.
