What better product to use for an antacid promotion than a hamburger yo-yo? You put the hamburger down, but it keeps coming back up. Actually, there’s more to this campaign than the clever product choice – Citrosodina chose this item for an important reason. Too many people had viewed the antacid as a medicine, whereas Bayer wanted them to focus on its “pleasant and bubbly taste”. Going with a lighthearted promotional toy allowed them to change up their image without spending a fortune.
