Even though, indirect advertisements which utilize entertainment program, drama and talk show has been
popular as a method to advertise not only products and brand but also policies to people, it is hard to find
research about measuring effects by issue placement in TV programs so far. In this research, we considered
that distinctions might exist between PPL(Product Placement) and IPL(Issue Placement) in terms of inferring
exposure motivation, and we verified IPL effects by setting exposure type(explicit arrangement/suggestive
arrangement) and exposure time(high/low) as independent variables and public interest awareness as a parameter. Moreover, we examined moderating effects on policy involvement and prior attitude. By this
study, we could figure out that obviously, there was a difference in public interest awareness according to
exposure types and times, and level of public interest awareness gave meaningful effects on attitude toward
IPL and policies. Additionally, we verified that prior attitude could be a significant moderating variable in
IPL effect.
