Documentaries are powerful tools in creating connections with their audiences (Bondebjerg, Smaill, 2009) as they tell a story about real life with claims to truthfulness (Aufderheide, 2000). Whilst evidence to date has demonstrated that documentaries allow for social change through engaging audiences to come together as a collective group to address social issues (Ahn, 2021; Hart, 2024; Hawes, 2021). We don’t know the systemic extent that docu-series have within Australia or globally. Thus, this study advances our knowledge in this area by being the first to examine the influence that the docu-series’ “Old People's Home for 4 Year Olds” and “Old People's Home for Teenagers” had on society through a sequential mixed methods study. This study collected data from the public using a cross-sectional survey of 821 members of the Australian public and by conducting a web-scrape. To further examine the views of researchers, organizations, and intergenerational facilitators, this study also conducted 9 focus groups and 20 semi-structured interviews, involving a total of 44 participants: 14 researchers, 15 organisational representatives, and 18 intergenerational facilitators. The findings reveal the powerful impact that the ABC series had on shaping attitudes towards ageing, increasing comfort levels in interacting with older adults in residential aged care, improving the appreciation for intergenerational work and programs, raising the profile of intergenerational programs globally, creating new career pathways, attracting new grants, unravelling stereotypes about ageism and sparking new research into intergenerational practice which provides a stronger evidence base for the value that intergenerational programs have in society.
