Findings released from a study by CNN International suggest that brands that choose multimedia campaigns to communicate their advertising messages are more memorable to consumers and are more likely to enhance perception of their brands. The CASE study (Cross-platform Advertising Study on Effectiveness and Engagement) consisted of a two stage approach. Stage one involved a multinational online study of cross-platform effectiveness in which consumers were exposed to diverse media experiences. Stage two measured attention and engagement through a variety of techniques including biometrics, eye tracking and in depth interviews.
