A Christian consultant has praised a national advertising authority for its decision to crack down on gender stereotypes in ads. Committees of Advertising Practice (Cap) said on Thursday that advertising that uses potentially harmful gender stereotypes such as mothers cleaning up after the family alone or fathers failing at simple household tasks is to be banned next year. The decision follows a review earlier this year which found that some advertising could reinforce harmful gender stereotypes, which in turn could restrict the choices, aspirations and opportunities of children, young people and adults. Natalie Collins, who trains youth workers and owns consultancy Spark agreed with Cap. She told Premier: "We can often underestimate the impact of adverts, but companies pay an awful lot of money to advertise because they know how powerful it is in selling products.
