By means of comprehensive and innovative solutions IMS S.A. conducted a successful promotion of Orange cell phones. As part of the project for Orange we prepared an advertising campaign broadcast on Instore radio in 146 shopping centres all over Poland. The aim of the promotion was to support sales of two phone models: Samsung and Sony Xperia including an offering of 6-month free subscription for persons transferring their number to Orange. In addition, activity on Instore radio was a prolongation of the advertising campaign run in the other media. Highest quality of sound emitted from loud speakers and a suitably adjusted advertising campaign guaranteed success in sales. Such solution helped customers considerably in making their purchasing decisions.
