Brand authenticity: 25 Years of research

Abstract Twenty‐five productive years have passed since the late Barbara Stern called for marketing scholars to take the topic of brand authenticity into consideration. Brand authenticity is now believed to be a core asset in mainstream marketing, yet confusion surrounds the nature and usage of the term. Using the Antecedents, Decisions and Outcomes format initially developed by Justin Paul and Gabriel Benito as an organizing framework, this article seeks to consolidate an area of thought characterized by multiplicity and excess of disparate meanings. Based on the extensive coverage of studies published over a period of 25 years between 1994 and 2019, extant literature on brand authenticity is reviewed. Three primary streams of research are identified: (1) characteristics that distinguish the ‘real thing’ from the fake, (2) the legitimizing function of authenticity and (3) emotional and moral aspects of authentication. Despite substantive contributions over the last 25 years, many areas of brand authenticity remain underexplored. By synthesizing extant literature, the aim of this study is to identify gaps in knowledge about brand authenticity and to prepare for a future research agenda guided by intersectionality.
