Advertising is a booming activity both in the physical realm and on the Internet. Online advertising is growing and is subject to legal standards, although some self-imposed ethical standards for the industry are needed. This has been called self-regulation. This article examines the important role that self-regulation can play in addressing advertising that uses degrading and discriminatory images of women that compromise their dignity.
