This study examined the relationships among the personality traits, media brand personality, and media use of consumers of the six largest electronic newspapers in Taiwan. Based on a literature review, this study identified nine brand personalities, three of which were negative brand personalities and the remaining six were positive brand personalities. Adopting Sirgy’s self-congruity theory, this study predicted that five major consumer personality traits would correlate to the brand personalities of the six electronic newspapers, which in turn would be demonstrated to affect the frequency of use of these newspapers by consumers. This study adopted a questionnaire survey to collect data, and 426 undergraduate students in the field of communication studies completed the questionnaire. The data analysis revealed that most respondents preferred the brand personalities of being competent and responsible, which were characteristics that also influenced their use of these electronic newspapers.
