Massive Information Stockpile Guides Humanity's Course

Sixty one CD-ROMS for every man, woman, and child on Earth.
That's the amount of global data humankind stored on devices of every kind in 2007 -- 295 exabytes, or 80 times more information per person than exists in the historic Library of Alexandria, Egypt, according to a study published in the journal Science.
"We tracked 60 analog and digital technologies from 1986 to 2007," said study co-author Martin Hilbert, Ph.D., an information researcher at USC Annenberg School for Communication & Journalism.
