"How much information?" redux

The classic UCB "How Much Information?" study has been updated for 2003. It's full of scary, scary numbers - especially when you remember that in 7000 or so years of human history up to 2000 we only (only?!) created and stored 12 exabytes of information.

In 2002, taking into account print, film, magnetic and optical media, five exabytes of new information was created (five exabytes of information is equivalent in size to the information contained in half a million new libraries the size of the Library of Congress print collections). 18 exabytes of information flowed across all the available electronic channels.

The amount of information generated per person has risen from 250 megabytes per year to over 800 megabytes per year - in just 3 years.
