"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.

*thoughtful frown* No wonder it's seemed a lot harder to get through all the junk out there to find real news.
Hmmm... do they have any decade-long trends? I would *really* love to see those.

looking at in more detail, those 18 exabytes cover TV, radio, phone and Internet and 97% of it is phone conversations. That's an interesting area - do conversations count as 'creation's or as data? I tend to think of data as deliberately created or collected (log files as well as photographs and music and writing and other documents); a radio program is data to me in a way that a phone conversation isn't. I think it's an interesting mix that they're measuring.

I just said to Sue: "Do you know that last year we created almost half the amount of information that we've created in the last 7000 years of human history?"

She said: "Sadly, most of it was about protocols for ordering stationery online."

even worse: it was cold callers trying to sell you double glazing and business men saying 'I'm on the train!'
