This study examines two marketing campaigns on the social media platform Twitter by the brand Nike, with the campaigns involving American football player Colin Kaepernick and tennis player Serena Williams respectively. The study specifically explores how Nike utilizes socially and politically progressive values in these marketing   campaigns and how users then respond to it on Twitter, with the source material consisting of four Twitter-posts, two by Nike and one each by the two athletes involved, as well as the replies by other Twitter-users to those posts. The replies to these four Twitter-posts were then sorted into reply types for each post, in other words categorized according to the sentiments and attitudes in the replies that were most prominently and frequently expressed. A grounded theory approach was used thereafter in order to apply relevant theoretical perspectives to the reply types and original posts, through which the source material was split into several analytical themes. The theoretical perspectives used in the analysis were Rosalind Gill’s postfeminist sensibility, Ron Von Burg and Paul E. Johnson’s writings on nostalgia as a critical perspective, Ernesto Laclau and Chantal Mouffe’s floating signifier concept, Eduardo Bonilla-Silva¨s racial grammar theory, Susan Cahn’s writings on female athlete stereotypes, and Lauren Copeland’s writings on postmaterialism. The analysis showed that Nike utilized socially progressive causes such as racial and gender equality in an individualistic way by conveying them through the identities of Williams and Kaepernick in their Twitter-posts. It also showed that the replies to the marketing in turn also focused on the identities of the athletes, with repliers either declaring their approval or disapproval of Nike and their marketing campaigns based on whether they were ethically and ideologically aligned with the progressive causes and values that the athletes were proxies for in their respective marketing campaigns. Ultimately, this study revealed an individualization of political expression on social media, both when a corporation like Nike uses it to improve their brand image and in how individuals engage with political and social issues.
