Abstract:

The 'long tail' of digital media creates new challenges, not only for audience measurement but also for the design of media research databases, analytical systems and reach/frequency models. Current reach/frequency and optimization models generally work from the 'bottom up' as individual media units are selected and combined one at a time. This paper describes a 'top down' solution for Out-of-home and its broader implications for increasingly fragmented media, notably digital and on-line, whose currencies are produced by the integration of diverse data sets.
