shelf shout
n.— «The level of interest expressed by the marketing world in the new exhibition is indicative of packaging’s growing profile in the marketing mix. As advertising revenues rise and the recession bites, so the need for a point of difference, for competitive edge, for “shelf shout” has never been greater.» —“Marketing Services Reports On The Creative Packaging Exhibition” by Amanda Burnside Marketing Jan. 31, 1991.
