Advertising restrictions continue to pile on for the gambling industry in the U.K. The Committee of Advertising Practice has announced new rules to keep gambling ads away from kids, The Guardian reports.

The two new rules are simple enough. First, gambling ads can’t be on any website or computer game that children are likely to play. With the wealth of demographic data and targeting tools available to advertisers, they are expected to make every best effort to keep their content away from users who are under the age of 18.

Secondly, gambling advertisers can no longer use celebrities in their ads, as well as any person who appears to be under the age of 25. The thinking is using popular or youthful people in ads has an added effect on impressionable young minds.

The rules go into effect at the beginning of April 2019. It will be interesting to see how they apply the new standard, as what content appeals to young audiences could be a matter of debate. YouTube stars, for example, can be quite popular with young teens while offering fairly adult content matter, with gambling sponsorships supporting them.
