Mastercard launched its "Priceless" campaign twenty years ago. It still remains one of the most iconic marketing strategies today, despite how much the world has changed. Raja Rajamannar, Mastercard's Global CMO & CCO, says the campaign is still relevant because the human experience will always be important. Rajamannar also discusses Mastercard's use of new technology in its marketing. The company recently launched a VR experience with crystal-maker Swarovski to change the way you shop. Mastercard also launched its new Masterpass cardless payment system. Rajamannar dives into the ways the company is changing the retail experience.
