Brand extension strategy is a component of brand management rooted in categorisation theory. The research outlined in this invaluable book provides a pathway for academic research in this field. Further to this it allows professionals to explore determinants of success for e-brand extensions in order to prevent the dilution of a brand. This project reflects realistic consumer perceptions and expands upon the inter-relationships between various factors. In taking account of these factors the author explains the process of how consumers transfer from traditional media usage to online news media. Based on academic theory and real-life situations, Yen provides a systematic explanation, thus providing managers with practical assistance and in- depth understanding of developing e-brand extensions.
