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.

If you drink it now, would you stop? Would you forget that it exists even though it's on store shelves, in vending machines, and pushed at several restaurants? Who would stop?
