In an era of constant challenges to conventional wisdom about the rela
tive effectiveness of various promotional tools, marketers are becomin
g increasingly aware of the value of publicity. Yet scholarly attentio
n to this element is limited primarily to cursory textbook treatment.
This paper draws upon communication and information processing theory
to establish a framework for the development of propositions about adv
ertising and publicity, in terms of their relative impact upon consume
rs' motivation, ability, and opportunity to process information. It al
so identifies a need for and suggests an approach to the systematic em
pirical comparison of these two promotional formats.
