Frequency of advertising exposure is one of the crucial determinants of increasing brand awareness. From consumers' point of views as the quantity of advertising rises, the attitude of the individual toward the advertising message also worsens and leads to boredom. Thus, faced with rising TV advertising costs, it is important to investigate the consumers' at6titudes toward the commercial. The purpose of this study is to explore whether consumer's purchase intention is affected by a stimulus of the frequency and length of TV commercial exposure via brand awareness, perceived quality, commercial attitude, and brand attitude. In this paper, we used a five-minute and frequently aired range hood advertisement that targets on the Chinese-American audience to measure how consumers respond to the stimulus and what variables influence their purchase intention. The major finding of this research indicates that perceived quality is the most powerful variable to affect consumers' purchase intention. As the data is constricted to the Chinese-American population, and the product introduced in the commercial belongs to durable and shopping goods categories, the authors will not generalize the conclusion to populations with different demographic backgrounds and to other product categories.
