This study examines the influence of product placement types on the brand awareness in the context of application programming in social media network. The authors develop four product placement types, i.e., integrated prominent, integrated subtle, non-integrated prominent and nonintegrated subtle product placements respectively. In addition, they use the construct of "flow state-achieving" instead of "program involvement" to analyze its mediated role on the relatedness between product placement types and brand awareness. The results show that product placement types have impact on brand awareness, especially more significant effects from the types of integrated prominent and non- integrated prominent. The users with high flow state-achieving have less brand awareness then those with low flow state-achieving. Moreover, the mediated roles of flow state-achieving are varied among the product placement types. There is a part of mediated effects on integrated prominent placement, but no effects on integrated subtle placement. However, there are mediated effects on nonintegrated placements, no matter with the type of prominent or subtle.
