The 21st century is unthinkable without advertising. Wherever we go we are surrounded by advertising posters, insignia, public flyers, social ads and numerous advertisements that complement the television content. Advertising and commercials are concepts that can not be overlooked in today's digital age. The purpose of advertising is selling a certain product or service to consumers. In order to send a message to specific target groups, advertisers often create and send special messages addressed to children and young people, and to what extent the advertising industry uses juvenile consumers, children, will be treated in this work. This paper presents what the concepts of advertising and commercial mean and how they evolved through history. The aim of this study is to study television commercials broadcast on Croatian commercial television and to determine whether and to what extent children are presented in them. In the two-week period, quantitative analysis of content on RTL television was carried out, followed by two-week quantitative analysis of content on NOVA TV. The results deny the set hypothesis and show that children are present in less than 50% of the total broadcasting on RTL and NOVA TV in the morning and evening period of broadcasting. Further, the results show that there are a number of advertisements that, though not showing children as actors, use tools like animated voices and animated characters that suggest that advertisements address the children. Since the media have become an inevitable part of every person's life, including children, it is important to conduct such research to investigate whether children are being used for advertising and thus suggesting possible negative consequences.
