Subliminal messages: we buy and we don't know why, or how our brain can associate "Money=KFC"

Subliminal messaging is illegal in the UK because it breaks the rules of your statutory rights as a consumer to make your own uninfluenced decisions on products. In the US it seems not to work like that, at least if we take a note at this KFC commercial.

This commercial makes your brain processing an image of both the product and a dollar bill. Seeing them together, your brain processes it as 'money= KFC' and so a few days later you might walk past KFC and decide to buy the product. Seemingly of your own choice, but actually you've ended up making a decision that KFC influenced your brain to make.
