How much data and information do we in the U.S. consume? What kind of data is it? University of California, San Diego (UCSD) researchers asked these, and many other questions, in a just released research report (PDF) which contains stunning results.
My emphasis from their executive summary: "In 2008, Americans consumed information for about 1.3 trillion hours, an average of almost 12 hours per day. Consumption totaled 3.6 zettabytes and 10,845 trillion words, corresponding to 100,500 words and 34 gigabytes for an average person on an average day. A zettabyte is 10 to the 21st power bytes, a million million gigabytes. These estimates are from an analysis of more than 20 different sources of information, from very old (newspapers and books) to very new (portable computer games, satellite radio, and Internet video). Information at work is not included."
That's a lot of data! What impressed me about their findings was that they took in to account multiple source inputs since, as I've found, many of these research studies focus on the new, internet-centric data consumption as though traditional forms of data delivery (the "old" above) are suddenly irrelevant.
