Abstract:
The study intends to compare the advertising effectiveness, both in terms of advertising and brand recalls, between 30 and 15 second television commercial (TVC). There are 3 hypothesises; 1. A 30 second TVC will yield a higher recall scores, for both advertising and brand recalls, than a 15 second TVC. 2. A single exposure of a 15 second TVC will give a higher than 50% of the recall scores derived from the same TVC with twice exposures. 3. A 15 second TVC with twice exposures will give higher scores of advertising and brand recalls than a 30 second TVC. There are two treatment materials, one 15 second, and one 30 second TVC, and both of which are edited from the same original commercial. Treatments were inserted in a mock up program that are similar to real TV Program. There are 45 subjects who are randomly selected from the voluntary lists of students. Subjects are randomly assigned into 3 experimental groups, each with 15 subjects. Measurement was done by using free and cued recalls. Statistics analysis consists of ANOVA, t-test, and Chi-square. The findings are as follow; 1. The effectiveness of advertising and brand recalls between 30 and 15 second TVC are not statistically different at the 0.05 significant level. 2. A 15 second TVC is less effective than twice 15 second TVC as measured in terms of advertising and brand recalls. The level of statistical difference is at the 0.05 significant level. Recall of a single exposure 15 second TVC is estimated as 30% of twice exposures. 3. A twice exposures of 15 second TVC are more effective than a single 30 second TVC as measured in terms of advertising and brand recalls. The differences between the two are significant at the 0.05 significant at the 0.05 level.
