I think it's the difference between brand names and non-brand names. Tylenol is a brand-name thus tries to distinguish itself from the generics on the shelf next to it. This happens in the UK/IE as well. As a comparison. Panadol (UK/IE) brand name for acetaminophen: https://www.google.de/search?q=panadol&tbm=isch https://www.google.de/search?q=panadol&tbm=isch Walzyr. US "generic" anti-histamine: https://pics.drugstore.com/prodimg/419979/450.jpg https://pics.drugstore.com/prodimg/419979/450.jpg Claratin. US Brandname anti-histamine: https://images-na.ssl-images-amazon.com/images/I/91rArvDAp9L._SY355_.jpg https://images-na.ssl-images-amazon.com/images/I/91rArvDAp9L... The US also tends not to have true generic drugs, but 'store brand' generics. So a store will carry Tylenol + a single store brand generic, instead of Tylenol + 5 different companies generic brands.
