This is a study on preference and memory of TV commercials for food service products and on the processes of relevant attitudes and purchasing activities. The results of this study showed that the higher preference for commercials, the higher rate of memory and that a business with high preference for commercials had all of six variables in the process of purchasing behaviors at the high mean. In conclusion, a food service provider should consider preference to make efficient commercials for consumers in implementing commercials; such preference for commercials may be favorable for attitudes toward brand and commercials as well as for the future memory of the commercials, which have immediate effects on the future purchasing behaviors.
