investigated the extent that consumer perceptions and reactions to brand extensions spill
over to the parent company. And, if there is a spillover effect, they asked what are the
potential risks or benefits to the parent company? ( Loken & John, 1993) has focused on
whether spillover exists for perceptions of the brand name vis-*-vis consumer perceptions
or beliefs or financial effect toward the brand name. In contrast, the paper by Roedder et al
examined whether spillover exists for perceptions of individual products marketed under
the brand name. The findings indicate that positive spillover effects are negligible, but that
negative spillover effects are evident for some types of established products.
Diversification: Successful Examples
Near one end of the spectrum, Dell has maintained a focused link between its brand and its
core
product line: personal computers. At the other end is Disney. In the 1950s, that company
too had a focused brand, which signified world-class animation, mainly for children.
Today, Disneys businesses include films, television, publishing, software, theme parks,
hotels, cruises, and even an entire town -Celebration, Florida (Court, Leiter, & Loch 1999).
The companys name now represents the broader concept of “wholesome entertainment and
living at any age.” Dell has decided to remain focused for now, while Disney elected – and
managed – to diversify. The crucial question for CEOs is which camp they want to be in.
As these examples show, a strong company can do well in either. But when we broke down
the figures showing that strong brands earn total returns to shareholders 1.9 percent above
7
the industry average, we found that focused brands (such as Dell, Levis, Sprint, and
Gillette) earn 0.9 percent more than the average, while diversified brands (such as Disney,
GE, and American Express) earn no less than 5 percent more!
Negative effects of Brand Extension:
Damaging effects from extensions/ diversification come from the following factors: failure
of the extension product lack of fit between the original and extension product categories
(Keller and Aaker 1992;Loken and John 1993; Park, et al. 1992; Romeo 1991) failure to
capture new market opportunities, when the brand, in an attempt to cover both the new
opportunities as well as its core business, ends up being generic and therefore right for
neither When a brands offerings or customer targets have become so diverse that the only
thing tying them together is
