Big Data Obsession is Treasure Trove for Comms

The Harvard Business Review recently put some teeth to the notion that businesses are increasingly being driven by data with a story that broke out the amount stored by various companies through 2012. Walmart, for example, collects more than 2.5 ”petabytes” of data every hour from its customer transactions.

For some perspective on this, one petabyte is equivalent to 1 million gigabytes or about 20 million filing cabinets' worth of text.
