Decency is the measure of an object's worth and value. See Decency. The category of issues that includes matters of "sex and decency in advertising" is a constant and ubiquitous problem concerning products, services, concepts, claims and imageries eliciting reactions of distaste, disgust, offense or outrage when mentioned or presented in advertisements. Issues such as decency are more difficult to define and handle because they reflect a large variety of personally subjective, culturally related and historically changing values and attitudes.
