X is considered to be one of the most popular icons in the field of advertising. In 2005, when ICICI Prudential came up with X, the icon for its insurance services, it enjoyed a brand recall of 92 per cent next to LIC’s 97 per cent, according to AC Nielsen survey.
X, a hapless middle-aged man, worried about where to invest his monies, was initially meant to be just a radio spot. Over time, however, X got famous and then it was used in the TV commercials as well.
What boosted the brand recall was X that broke away from the clutter at a time when there were far too many insurance companies wooing potential customers.

Id X.
