Forty-five years of celebrity credibility and endorsement literature: Review and learnings

Celebrity credibility constitutes a significant portion of the celebrity brand endorsement literature. While this field of research is mature with a rich history of 45 years, it lacks a bibliometric analysis that traces its evolution. We address this gap by conducting a structured and bibliometric review of the literature. Through this hybrid review, we highlight the most cited articles, authors, journals, theories, methodologies, and sub-research themes in this body of knowledge. Our findings demonstrate that this research area is inter-disciplinary and significantly influences research within and beyond the business context. We identify a shift in credibility literature towards the digital media context. Further, this review indicates that a comprehensive sub-discipline of celebrity endorsement underlies the evolved literature of brand communication. Finally, we present an antecedent-consequence framework of source credibility. We conclude with theoretical contributions, managerial implications, and future research propositions using the Theory, Method, and Context (TMC) framework.
