No matter what time scale you pick, there's still a point where ad spending costs more than you benefit. As time passes, the boost from any campaign decays. For any particular person you only need to show them so many ads to maintain awareness.

Mmm. Sometimes. Sure, you can obsessively measure audience and sales numbers, but if you don't have any controls then it becomes nearly impossible to figure out how much of that came from ads and how much came from everything else in the entire world.

it is true that that profit/loss point exists, but it may be impossible to measure. But it's very clear that 75+ years of Coca Cola marketing strategy has produced the situation where any human on earth immediately associates "Coca Cola" with soft drink.

If Coca Cola cut advertising 90% this afternoon, they likely wouldn't see the consequences until a new generation or two grew up.
