Abstract:

This paper describes the development by Initiative Media of Matrix, a new tool for optimizing multi-media campaigns. Based on a survey held in 12 countries amongst over 24,000 respondents, the main purpose of which was to establish the overlap in the use of different media. Reach and frequency for any combination of media can be calculated by combining these figures with regular media surveys. As media contacts may differ in value for delivering desired communication effects, different weighting methods are proposed. The first is based on the expert opinion of a large number of media specialists; the second is database oriented; and the third is based on econometric modelling of the multi-media mix. However, it appears most available tracking studies do not provide the data needed for proper modelling. Therefore an alternative layout is proposed for tracking studies.
