This study aims to match the most suitable time slots and FM (Frequency Modulation) broadcast station programs with various commercials in
Kaohsiung metropolitan area. Due to the immature evaluation methods of the commercials on mass media, most radio advertisers choose advertising
agents to broadcast advertisements by their preference for programs and time slots, which is unprofessional and ineffective. This study
employed factor analysis to identify 9 dimensions,which is the product type; and conducted correlation analysis with the time slots and
program type to match the time slots and and programs with the commercials. Hopefully, the results of the study may help advertisers make a better and more economizing decision on risk management.
