I think with a company like Coca-cola, it is a little bit of a different approach. Taking Coca-cola as the example. My money is their ads are not placed there to get you to buy a 6-pack online. It is so when you see it, you go, 'damn a coke actually sounds really good right now.' And then you proceed to walk tot he fridge for one or next time your out and about buy one. However I would say that a product such as coke is a specific case. Some ads are for targeting people to go to their online store, then I am sure ones like coke exist to put the idea in your mind next time you stop for gas.
