Brand extension that makes sense: Would you buy a Harley-Davidson cappuccino machine?

Certain brands bring to mind particular cultures, and consumers react more positively to brand extensions when products match expectations about cultures, according to a new study in the Journal of Consumer Research. That's why a Budweiser barbecue sauce might be more successful product than a Harley-Davidson cappuccino maker.

Examples of culturally symbolic brands include Budweiser (American), Sony (Japanese), or Corona (Mexican). The authors look at what happens when a culturally symbolic brand extends its product line by creating new products.

The authors focus on a part of consumer deliberation that is based on cultural congruity—the extent to which a brand and its product automatically bring to mind knowledge about a culture. "This process operates independently of consumers' perceptions of fit between the brand associations and the product attributes, or their inferences about the brand's manufacturing expertise due to its country-of-origin associations, and can influence extension evaluations independently of these factors," the authors explain.

In short, when a brand associated with a culture fits into personal understanding of the culture (cultural schema), consumers have an easier time processing and therefore accepting a new product.

The authors found that participants had positive feelings for culturally congruent extensions (like a Sony electric car), while they had less positive feelings about a Sony toaster oven; they found the idea of a Sony cappuccino-macchiato maker even less appealing. The authors say the effects emerged only when both the brand and the product were culturally symbolic.

"A brand's cultural symbolism can be a liability or an asset, and to harness it profitably, a manager needs to understand the cultural symbolism of the potential extension categories under consideration," the authors conclude.
