The volume is one of the most comprehensive empirical TV advertising studies in Germany over the past 30 years, featuring 3,320 analyzed commercials from 26 advertising sectors. For the study, the German TV channels RTL, RTL II, and Pro7 were analyzed based on 36 criteria. The key areas of interest include: What is being advertised, how, with whom, to what extent on German television, and how understandable the advertising claims are for consumers. This is examined against the backdrop of increasing advertising regulations, as well as the criticism that TV advertising is particularly targeted at children and adolescents with promotions for less healthy foods, contributing to their rising obesity rates. Important study focal points include food and confectionery advertising, alcohol advertising, and the use of children, adolescents, men, women, and celebrities in advertising.
