The £1.5bn total means that gambling adverts account for 8% of the total UK advertising market, which according to market research group Nielsen is valued at £19bn.
It is also more than seven times the annual advertising spend of Proctor & Gamble, the company behind brands including Pampers and Gillette, which is the UK’s biggest single advertiser – and 150 times the £10m that gambling firms give via a voluntary levy to GambleAware, the main recipient of funds for addiction treatment and research.
