My favorite marketing technique is Ambush Marketing which is a form of marketing where a company takes advantage of the publicity provided by a major event to create awareness for its product without having to contribute or make any financial commitment to the sponsorship of the event. Every time the camera zooms in on the coach for his reaction to a play, there’s always the same group of people wearing the same t-shirts sitting directly behind the bench. It is when you realize they’re promoting a brand.
