Use geotargeting to target a specific state or small country pour massive amounts of money relatively to the small target zone and monitor changes in consuming habits, brand reach and recognition etc. I'm not sure most consumer product companies know how to do it properly. Also some brand advertising isn't always about gaining ground, its about not losing ground to competing brands that do advertise, if Pepsi is pushing a huge TV campaign, Coke feels the pressure to play catch up.
