Product placement is a widely used method of marketing these years. But studies are mostly focus on product placement of commercial products, neglecting the fact that it is also commonly exist in non-commercial information. So, in this study, we use experimental method to compare the effect of different message type (commercial and non-commercial), and discuss the influence in which way it present (visual only and combines audio-visual). In this study, we discover that: 1. In comparison with commercial information, non-commercial product placement works better in the effect of product placement. 2. Though there is no significant difference in information attitude and behavioral intention, different modalities product placement has significant and positive influence in memory and film attitude.
