By now, if we’re doing our job right, you should kind of get how digital advertising works. Companies collect information about you — like where you live, your age, what you buy online, what websites you visit and much more. And they use that information to target you with ads they think you will like so you'll buy their stuff. But you may not know that this is also happening on television. It's called addressable advertising, and it means your cable or satellite TV provider is showing you ads on your TV that your neighbor might not see. Right now only a small number of the ads you see are targeted ads, but it's evolving fast because the money is good. Molly Wood talks about it with Tim Peterson, a senior reporter at Digiday. She asked him how the tech works.
