A reader writes: Last Sunday morning, Times of India readers experienced a strong odor emitted by the newspaper. It was supposed to be the coffee smell, perhaps a requirement from Bru, which had paid for the front bottom half page advertisement. However, far from smelling anything like coffee, it smelt like tobacco. Innovative advertising in newspapers is not new. In the past, readers have been given sample sachets, green tinted front pages and even heard a mini-recorder stuck to an automobile advertisement, which got activated when it was exposed to light. After the olfactory attack, I wonder what other senses are left to be exploited by the advertisers via print media.
