Unlike the United States, Great Britain has official censors that are empowered to decide which advertisements are acceptable and which are not. For the most part I’ve always thought this was an absurd arrangement, especially since the Advertising Standards Authority tends to be hypersenstive.
On the other hand, I cannnot fathom why a health organization would want to run an ad like this. A woman with a plastic bag over her head — yeah, that’s an image I want my five year old running across.
