While I read through this article, I found that there are s lot of case that related to subliminal messages but all of them were said to be hoax. In my opinion, the creator done this for a point and I think they do have effects on our mind. Even in children movie have those hidden message that we can somehow clearly see it.
"Over the years there have been literally hundreds of studies"..."these studies show that considerable information capable of informing decisions and guiding actions is perceived even when observers do not experience any awareness of perceiving".

Subliminal perception or cognition is a subset of unconscious cognition where the forms of unconscious cognition also include attending to one signal in a noisy environment while unconsciously keeping track of other signals (e.g one voice out of many in a crowded room) and tasks done automatically (e.g driving a car).
There are a lot of research need to be done in order to taking a stand in any of the controversial side of this matters.
