Verizon's technology can work a variety of ways. For starters, it can listen in on conversations — whether it be with someone else in the room or on the phone — and pick out keywords that would aide it in its duties.

Imagine arguing with your significant other and then seeing marriage counseling ads on the TV — or better, cuddling and then seeing ads for contraceptives!
