Gambling marketing portrays gambling as normal part of sports. This can create a public health risk, given the harm associated with gambling. This study explored Irish children’s exposure to and perceptions of gambling marketing in sports. Six focus groups were carried out with children aged 14–17 years who regularly watched sports. The researchers identified four main themes. First, sports consumption was mostly through mobile social media. Second, exposure to gambling marketing was high. Advertising for gambling was frequently seen on social media platforms as well as in everyday spaces and conversations with peers. Third, there were mixed responses about perceptions regarding gambling marketing through sports. Fourth, participants were skeptical of the claims made in gambling marketing.
