Celebrities are famous individuals, well known by many members of the public, who appear frequently in media content. When celebrities appear in the media alongside another cause, be it selling soap or promoting public health, the message becomes a celebrity appeal. Celebrity appeals are messages where a celebrity advocates for or is implicitly associated with a target behavior. In the context of health and risk-related messages, celebrity appeals can take the form of public service announcements, advertisements for health and risk-related products, or even news coverage of a celebrity’s personal struggles with a health issue or risky behavior. Research on celebrity appeals overlaps with the marketing literature investigating the effects of celebrity endorsements on product preferences and purchasing behavior. This work on the persuasiveness of celebrity endorsements demonstrates that celebrities can draw attention to a product or idea, but also that many other factors, like involvement, familiarity, source credibility, and endorser gender can moderate how persuasive a celebrity-based appeal is. Additionally, research on celebrity disclosures of illnesses reveal that these de facto awareness campaigns can elicit emotions in audiences and motivate behavior change. However, media coverage of celebrities has also been associated with harmful effects on lay individuals’ wellbeing, suggesting important caveats for message designers who rely on celebrities to garner attention for a cause or to motivate lay individuals to change their own health and risk-related behaviors. The existing empirical evidence on celebrity appeals and additional theoretical perspectives for understanding their potential persuasiveness provides many insights for message designers.

Critical studies of humanitarian discourses involve the study of the arguments, claims, and evidence that are used to justify intervention or non-intervention in key local, regional, national, or international contexts. These discourses can take the form of arguing over whether we should practice isolationism and not intervene in the sovereign affairs of other countries, or they can take the form of deliberations over the transcend needs of populations that cope with myriad disasters. In some cases these discourses are produced by foreigners who believe that the less fortunate need to be rescued from their misery, while at other times humanitarian discourses can be used in discussions about the human rights of the disempowered. Nongovernmental organizations (NGOs), nation-states, celebrities, medical communications, and militaries are just a few of the rhetors that produce all of these humanitarian discourses.

Celebrity politicians are having a profound impact on the practice of politics within the United States and United Kingdom in the 21st century. With the adoption of social media platforms, celebrity and image candidates have deployed new strategies for attracting constituents. Taken together, the proliferation of celebrity politics and the ubiquity of digital platforms have fostered a unique atmosphere in the contemporary political moment, wherein “outsider” candidates may leverage their fame to launch themselves into the public spotlight. In turn, through their celebrity brands and digital presence both populists such as the U.S. President Donald Trump and left-wing leaders including U.K. Labour leader Jeremy Corbyn have established an “authenticity” in which they “occupy” a public space to define their candidacies. Consequently, as celebrities and image candidates promote political agendas among target audiences/citizens, it is necessary to reflect upon their significance in election campaigns, policy agendas, and activism.
