This study explores how and why young people engage with MTV Shuga, a popular mass media campaign in South Africa, to understand what makes effective HIV edutainment. Young MTV Shuga viewers from the Eastern Cape, South Africa and their parents participated in remote individual interviews and focus groups in 2020. Qualitative data were transcribed and analysed using a thematic iterative approach. Young participants engaged with MTV Shuga for relatable, tolerant and complex stories about young people navigating HIV and relationships. These stories, which made viewers aware of sexual health services, inspired young people to reflect on how they might engage with different sexual health scenarios. MTV Shuga initiated conversations among peers, partners and some families about HIV that made them feel supported and equipped to tackle problems in their own lives. Complex, relatable, non-judgemental and youth-centred storylines can make HIV edutainment engaging to youth audiences. This approach allows space for reflection and inspires discussion and debate, turning young people from passive recipients of HIV messaging to active decision-makers. Television-based interventions can disseminate resources and knowledge into communities, however, watching them with parents can expose young people to judgement. HIV edutainment should therefore be available through different mediums so young people can engage in tolerant environments.
