You know a marketing buzzword has become a full blown phenomenon when it’s being used to describe things which totally cannot be logically be associated with the thing being advertised. A few years ago that marketing buzzword was HD. Now it’s 3D because animated and live-action 3D films are now the hot gimmick. When I was in a Duane Reade recently I saw Crest 3D Multi-Care Whitening Rinse. I suppose all mouthwash in the physical world is technically 3D, but I shudder to think about the people who were enticed to buy this product because it had “3D” written on it.
