Towards the end of 2011, the (then) Responsible Gambling Fund published a report which, inter alia, offers an overview of the research gaps in relation to the impact of advertising on disordered gambling. In this article, the authors of the report summarise their main findings. They conclude that evaluating the impact of gambling advertising is highly complex. Nonetheless, advertising forms an important component of the broader environment in which behaviour and attitudes are shaped. The empirical evidence base is weak and therefore conclusions about whether gambling advertising is associated with increased levels of disordered gambling cannot be drawn. However, there is some evidence that advertising alters perceptions and attitudes towards gambling. Yet, evidence demonstrating translation of this into behavioural change is weak. Particular attention should be given to vulnerable population groups such as adolescents and disordered gamblers. In view of further research, a set of recommendations is provided.
