While advertising has been shown generally to influence individuals' awareness and attitudes, there is no clear evidence that advertising contributes to criminal behaviour such as violence. However, in response to the Alcohol Harm Reduction Strategy (2004), both the Committee of Advertising Practice (CAP) and the Broadcast Committee of Advertising Practice (BCAP) strengthened the non-broadcast and broadcast alcohol advertising code rules. The regulatory bodies; the Advertising Standards Authority (ASA) and Ofcom, are undertaking work, designed to assess the impact of these regulatory changes. CAP and BCAP are committed to robust evidence-based rules. If there were new evidence showing major harms, then the codes, or their interpretation, may be reviewed.
