Let’s be strange: brand familiarity and ad‐brand incongruency Available to Purchase

Reports on an experimental study where the effects of ad‐brand incongruency on a familiar brand and an unfamiliar brand, respectively, are measured. Building on theory on information incongruency, tests the notion that ads that are incongruent with the brand image may be more effective in raising brand interest and brand memorability. However, this depends on the familiarity of the brand: the incongruency reinforces the existing associations for a familiar brand by increasing elaboration of the brand message, whereas the incongruent associations may take the upper hand for an unfamiliar brand with weaker existing associations. The results show that ad‐brand incongruency enhances brand attitude and brand memorability and reduces ad memorability for the familiar brand. The only significant effect of ad‐brand incongruency for the unfamiliar brand is a reduced brand memorability.
