Big Data, Big Brother

Forget privacy in this digital age. While looking online at an item on Crutchfield’s site, I called their customer service for more info. Without asking me any questions, the sales rep knew exactly which item and which webpage I was looking at. I’ve never done business with Crutchfield before - meaning they wouldn’t already have my info in their database.    If marketing software can do this, just think what black hats can do.  Pretty scary stuff.
