How much information is there in the world? Scientists calculate the world's total technological capacity

(PhysOrg.com) -- Think you're overloaded with information? Not even close. A study appearing on Feb. 10 in Science Express calculates the world's total technological capacity -- how much information humankind is able to store, communicate and compute.

"We live in a world where economies, political freedom and cultural growth increasingly depend on our technological capabilities," said lead author Martin Hilbert of the USC Annenberg School for Communication & Journalism. "This is the first time-series study to quantify humankind's ability to handle information."

So how much information is there in the world? How much has it grown?
