Yes, but not because advertising lets people know about Coke. The people who still know about Coke would be the same after a year, I imagine.

The mechanism of how advertising works seems to be not that. I think repeatedly brand exposure does something to the brain and decision making that we don’t fully understand.

Familiarity, I think.

Exposure breeds familiarity, which breeds desire, I think.

Even if all you hear is an occasional ad about the company, you might get curious and research them yourself.
