SEATTLE—  Amazon has changed its main shopping-app logo, after commentators said the recent redesign made it look like Adolf Hitler. Launched at the beginning of the year , the icon depicts a strip of blue tape over an Amazon "smile" logo. But some observers said it resembled a toothbrush moustache, associated with the Nazi dictator. The technology giant has now changed the design to a folded blue tape, following customer feedback. One Graphic Designer said “Unfortunately for Amazon, the visualisation of their parcel tape on the original logo will immediately be associated as a Hitleresque moustache, as that shape is forever embedded in our [subconscious] brains as such - not the best association for a brand that wants to create delight on the doorstep.”
