Think the picture on a box of brownies is appetizing?
Soon you may be tempted by the smell of freshly baked brownies as well, CBS-2 consumer reporter Kristin Cole explains.
The scent isn't coming from a mix inside the box but from an electronic label programmed to release a bit of the mouth-watering aroma every time the shopper walks down the aisle.
"As you approach the coffee, they will send out the coffee aroma when they sense you're coming by," says Peter Harrop of IDTechex.
What's behind the trend? To get your hunger hormones cranked up and induce you to open the wallet.
