Technical advancements and plunging costs for digital storage mean that government surveillance programs no longer have to be selective about the data they store. And with the average person leaving a trail of Web browsing, emails, text messages and more, there’s plenty of information that can be filed away on individuals.

The Caucus at The New York Times:
John Villasenor, an electrical engineer at the University of California, Los Angeles, studied the plummeting cost of computer data storage and reached an astonishing conclusion: It will soon be technically feasible and affordable to record and store everything that can be recorded about what everyone in a country says or does.
… Mr. Villasenor, also a senior fellow at the Brookings Institution, estimates that to store the audio from telephone calls made by an average person in the course of a year would require about 3.3 gigabytes and cost just 17 cents to store, a price that is expected to fall to 2 cents by 2015. Tracking a person’s movements for a year, collected from their cellphone, would take so little space as to carry a trivial cost. Storing video takes far more space, but the price is dropping so steadily that storing millions of hours of material will not be a problem soon.
