Advertisers engage celebrities to endorse their products. This chapter hinges on the meaning transfer theory of McCracken that says that celebrity image can be transferred to items that users buy. Using the survey method, this work examined if celebrity endorsements affect buying. Copies of the questionnaire were administered on 1,516 residents drawn from urban, suburban, and rural areas of Lagos and Ogun States, Nigeria. The Pearson correlation found positive relationships between celebrity endorsements and buyers' decisions. The tests show that celebrity endorsements influence the purchase decisions of the residents, and these buyers' avoidance of a product is more clearly influenced by celebrity endorsements. People buy products because of the celebrities that endorsed them. However, some respondents, especially those in the rural areas, were not as influenced into buying these products as are those from the urban and sub-urban areas. It is advised that advertisers pursue other avenues to draw patronage from this area.

This study is a meta-analysis of empirical studies in social media strategies and reputation research. The research goal is to give a clearer idea of the broad directions and paradigm shifts in Twitter usage discourse over the years. Its major goal is to examine thematic trends, theoretical framework and methodology that have characterized the discourse. Sixty relevant articles were identified, coded and content-analyzed. Findings revealed that dominant themes include stakeholder perceptions of communication strategies, social network sites, dynamics of global pandemic (i.e Covid-19 pandemic) and corporate reputation. Also, experiment, case study and survey are the dominant research methods that characterize research in this discourse. Findings also revealed large domination of the Situational Crisis Communication Theory (SCCT) and the Image Repair Theory. However, research in this area lacks significant empirical evidence from Africa and Nigeria in particular, where the global pandemic seems to be a recurring phenomenon. The majority of the reviewed journal articles were conducted in the Western clime, with little attention on Africa. Scholarship needs to move beyond this point to provide a holistic and balanced view on the crisis by exploring cases in Africa and particularly, in Nigeria. This gap will provide an opportunity for understanding the global pandemic (i.e. Covid-19) dynamics in Africa and will further determine whether findings can be consistent across the world.
