NPR's Marketplace reported
that advertisers were experimenting with genetically engineering food so that it would display advertisements.
For instance, it was possible to engineer burger patties so that as they cooked an image of "Mr. Pickle" appeared on the burger. At 160 degrees Fahrenheit, Mr.Pickle would even start to wave.
One ice-cream maker had also created cones with coupons inside the ice cream. The secret coupon code was revealed after you took a bite of the ice cream.
But consumers seemed wary of these food advertisements. One shopper said, "20 percent [off] isn't worth having to stare at ads at dinner."
