Many firms attempt to ensure the success of new product introductions by applying an existing, well-known brand name to the product. The strategy, known as brand extension, has become commomplace. In recent years, the strategy has been used in media industry. Especially, since the Internet started gaining in popularity in the mid-1990s, the newspaper industry has started applying brand extensions to online markets. For example, United Daily News, Chinatimes, and so on has developed websites of various types. However, we doubt whether it¡¦ll affect consumers¡¦ attitude toward the parent brand. For this reason, we attempt to figure out consumers¡¦attitude toward the newspaper brand when a newspaper office has introduced extensions with good or poor fit. Besides, in this study, we also propose that three factors including ownership status, product attributes, and dominance of the parent brand will influence consumers¡¦s evaluation of the parent brand. Previous research have provided mixed evidence about the reciprocal effects of a brand extension on its parent brand and rarely studied the impact of these four factors on parent brand evaluation, especially in media industy. As a result, we select United Daily News and Appledaily as two objects of the study and find out the extensions (websites) with good and poor fit of these two newspaper brands through group discussing. After T-test analysis, we have some findings as follows: 1.There¡¦s no significant effect of fit on parent brand attitude toward United Daily News, but there¡¦s significant difference for Appledaily. 2.The consumers who think of the newspaper brand as more dominant have higher evaluation of attitude toward the parent brand than those who think of the newspaper brand as less dominant, whether extensions with good or poor fit introduced. 3.The owners of newspaper brands have higher evaluation of attitude toward the parent brand than nonowners, whether extensions with good or poor fit introduced. 4.The product attributes of newspapers brands will affect consumers¡¦s attitude toward the newspaper brands.
