The chapter considers Dawkins’ (1976) conceptualisation of memes as culture units that spread from brain to brain through the process of imitation. Internet memes offer an alternative perspective through which to view young people’s health-related social media encounters. Drawing on the case studies (Chapters 2–7), I explore these data-rich narratives through three themes: (i) genre of participation; (ii) algorithms not people as transmitters of culture; and (iii) adults (teachers and parents). In so doing, I argue for the need for new spaces in which young people and adults can begin to explore their digital futures.
