Two weeks after the catastrophe, buyers still feel that the public could do without the typical saturation of adverts.

Many companies felt they needed to review the content and tone of their adverts and some even went as far as digitally removing scenes of the WTC towers from commercials.

Soft drink giant Coca-Cola has fittingly pulled its entire "Life Tastes Good" campaign. Commercial airlines and financial service companies cannot be seen to advertise and that mood is shared throughout as creatives struggle to create the right impression for their products.

Many American networks, certainly those broadcasting non-stop news coverage of the social and political aftermath, have filled commercial slots with appeals for the American Red Cross disaster relief effort.
