Amazon has quickly changed its main shopping-app logo, after commentators said the recent redesign made it look like Adolf Hitler. Launched in January, 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. Amazon told BBC News the first icon had been trialled in a few countries before the change had been made.
