Corporate brand value, a key corporate asset, has traditionally relied on stakeholder interactions, heritage, and corporate identity. In dynamic fast clock-speed industries (information technology and consumer electronics), we note that brand values change dramatically within a few years based on their innovativeness. Using grounded theory approach and multi-case study method we examine how Apple, Samsung, Toyota, and Coca-Cola sustained their most valuable global brands while Kodak and General Motors eroded the same. Certain key dynamic innovative capabilities are identified as best practices. We conclude with implications for managers and future researchers, along with some limitations.
