No but that's the trick, you're trying to directly link an advert with a purchase when you might not even be aware of that link because it wouldn't be that explicit. Like I said, beyond the straightforward call to action that is more suited for online ads because you can immediately act (click) on ad banners, TV ads' goal seems to raise a general brand awareness that would play an indirect role in purchase motivation. It may not be the main factor, but the hope is that it's going to be enough to sway undecided people, just because they will have been familiarized with the brand earlier.

There's nothing subliminal about it, but it does target the subconscient by simple image/sound association. Of course it doesn't work on everybody, but if it did work on you, you probably wouldn't know about it.
