Supermarkets Inc: Inside a $500 Billion Money Machine

The typical modern American supermarket stocks 48000 items, each battling for precious shelf space. How do they get there? Why are they arranged the way they are? In the CNBC Original documentary, "Supermarkets Inc: Inside a $500 Billion Money Machine," premiering on Thursday, January 27th at 9PM ET/PT, correspondent Tyler Mathisen goes inside the neighborhood supermarket and explores an industry that is using every device in its arsenal to learn as much as it can about you -- watching, trailing, and analyzing your shopping habits in ways you never imagined. Did you know that some stores use heat maps to track which aisles you walk down -- and which ones you don't? Or that they put the milk at the end of the aisle so you're forced to pass a hundred other items on your way to get it? It's all done to gain an edge in a cutthroat business built on razor-thin margins. CNBC cameras go behind the scenes at your local big box market, Whole Foods, and fading mom-and-pop stores to find out what the supermarket industry knows about you -- and what you don't know about them.
