This study discusses and provides a measure for the degree of stereotyping in advertisements. Applying this measure, the study shows to what degree gender stereotypes in advertising differ between public and private TV channels in Germany. The results show that gender stereotyping in advertising still prevails despite the change in the roles of men and women over the years. Contrary to their public mission, public TV channels do not show fewer gender stereotypes in advertisements compared to private TV channels. The degree of stereotyping as related to different stereotyping components differs significantly between these two types of channel. Gender stereotypes on private channels refer to role behaviour and physical characteristics and, thus, function as a means to sell a product. On the other hand, advertisements on public channels stereotype gender in terms of occupational status, and therefore interfere with the major goal of gender equality policy.
