This research aims at unveiling how the sports sponsorship is implemented in companies while studying brand sponsorship and its impact on the consumer and the company on the other hand. We have chosen sports events as our field of study. The empirical investigation is divided into three parts. The first is about the marketing aspect which is primarily concerned with the study of consumer behavior through a survey conducted to analyze the consumer impact on the purchase of the sponsor brand, considering the example of the 2012 qualification Olympic Games football game between Tunisia and Malawi. As for the second part, it deals with the financial in its relation to the company. The technical study event was adopted to learn about the investors’ reaction towards brand sports sponsoring. Taking the example of African Nations Championships every other two years starting from 1996 up to 2012. Finally, to support the outcomes of the two previous approaches, a semi-directive interview was held. Nine interviews were conducted, which provided us with more information about the perception of leadership. Based on these data that sport sponsoring places the influence of brand on the value of Tunisian companies; our conclusions further demonstrated that Tunisian firms will definitely benefit considerably if they develop sports sponsorship brand.
