Ads
do impact people and alter their behavior. Do you really think that corporations spend billions of dollars for no reason at all? That the management would not get the boot for wasting all that money for no reason?
It's easy enough to see the relationship between the launch of ad campaign A and spike in sales B. Sure, not all ad campaigns are a success but when they are, the spike in sales follows and is a measurable result. It didn't just happen by accident and there are copious examples of the phenomenon occurring to induce corporations to keep spending large amounts of money in an eternal effort to reproduce it.
Advertising works subliminally; it is not intended that you should be aware of its effect on your behavior. That is what explains the common misperception that "ads don't work on me." Well, maybe you
are the exception, but there are plenty of non-exceptions out there, believe me, enough to fund a multi-billion dollar industry.
On a more subliminal level, ads give the impression that the company will be around for a while since they can afford to pay for the time or space to advertise.
And that indeed is one of the purposes of advertising. It is a widespread misperception that ads are ONLY to prompt immediate sales. It's far more strategic than that.
I saw ads for 3D chalk and now I want some!
Then I looked at the price and I skipped it.
But they made ya look.
