Abstract
In this article, behavioral economics models behind 3F (fame-famous-fluency) are explained, and the case from the GSM operator sector is made. According to the marketing research and advertising agency System1 Group, the elements of a brand are fame, feeling, and fluency (3F). Fame indicates the brand's market share. Feeling points to the future potential. Fluency creates brand value. Within the framework of the 3F model, brand values of GSM operators are observed in the light of the findings obtained in qualitative technique conducted with professionals. The purpose of the model is not to convince the user (to base it on system 2) but to provide a great convenience in the user's perception (addressing system 1). According to System 1 Group, the traditional advertising model is based on convincing consumers' "system 2" thinking system. However, users' thoughts and feelings about the brand should be based on system 1. It is noted that while a user considers among GSM operators, does not remember (fame), has the neutral emotion feeling (feeling), and does not recall its distinctive features (fluency) about one of the operators based on the system 1 thought process. The suggestions for branding within the framework of the 3F model are discussed.
