Coffee is clearly the flavour of the season — at least for advertising innovation. In the past few months, The Times of India (TOI) printed two front-page advertisements that did more than extol the virtues of two coffee-related brands — they also smelled of the stuff. In effect, early morning readers in major cities literally woke up to the smell of coffee. In February, Hindustan Unilever printed scented ads of Bru Gold in three editions of Sunday Times. The previous fortnight it was Parle’s turn, with the launch of a coffee variant of its Hide & Seek biscuit. The ad appeared in five editions of the daily newspaper.
