According to a recent report1, the amount of digital content on the Internet is now close to five hundred billion gigabytes. This number is expected to double within a year. Ten years ago, a single gigabyte of data seemed like a vast amount of information. Now, we commonly hear of data stored in terabytes or petabytes. Some even talk of exabytes or the yottabyte, which is a trillion terabytes or, as one website describes it, “everything that there is.”2 The explosion of mobile networks, cloud computing and new technologies has given rise to incomprehensibly large worlds of information, often described as “Big Data.” Using advanced correlation techniques, data analysts (both human and machine) can sift through massive swaths of data to predict conditions, behaviors and events in ways
unimagined only years earlier. As the following report describes it: Google now studies the timing and location of searchengine queries to predict flu outbreaks and unemployment trends before official government statistics come
out. Credit card companies routinely pore over vast quantities of census, financial and personal information to try to detect fraud and identify consumer purchasing trends. Medical researchers sift through the health records of
thousands of people to try to identify useful correlations between medical treatments and health outcomes. Companies running social-networking websites conduct
“data mining” studies on huge stores of personal information in attempts to identify subtle consumer
preferences and craft better marketing strategies
A new class of “geo-location” data is emerging that lets companies analyze mobile device data to make
intriguing inferences about people’s lives and the economy. It turns out, for example, that the length of time that consumers are willing to travel to shopping malls—data gathered from tracking the location of people’s cell phones—is an excellent proxy for measuring consumer demand in the economy
