Hellmann's and agency Ogilvy Brazil came up with a novel way to encourage consumers to use mayonnaise for more than just sandwiches. The brand teamed up with supermarket chain St Marche to install special software in 100 of its cash registers. This not only recognized when consumers bought Hellmann's but clocked the other items they were buying, and came up with recipes that combined several ingredients, printing them out on the till receipt. In the first month alone of the three month experiment, sales increased by 44%.
