Limbic platform capitalism: understanding the contemporary marketing of health-demoting products on social media

The purposive design, production and marketing of legal but health-demoting products that stimulate habitual consumption and pleasure for maximum profit has been called 'limbic capitalism'. In this article, drawing on alcohol and tobacco as key examples, we extend this framework into the digital realm. We argue that 'limbic platform capitalism' is a serious threat to the health and wellbeing of individuals, communities and populations. Accessed routinely through everyday digital devices, social media platforms aggressively intensify limbic capitalism because they also work through embodied limbic processes. These platforms are designed to generate, analyse and apply vast amounts of personalised data in an effort to tune flows of online content to capture users' time and attention, and influence their affects, moods, emotions and desires in order to increase profits. Social media are central to young people's socialising, identities, leisure practices and engagement in civic life. Young people actively appropriate social media for their own ends but are simultaneously recruited as consumers who are specifically targeted by producers of limbic products and services. Social media platforms have seen large increases in users and traffic through the COVID-19 pandemic and limbic capitalism has worked to intensify marketing that is context, time and place specific, driving online purchases and deliveries of limbic products. This has public health implications that require immediate attention as existing regulatory frameworks are woefully inadequate in this era of data-driven, algorithmic marketing.
