This graduate thesis presents a contemporary image of children and childhood in modern media using the example of the YouTube platform. The qualitative analysis of the content covers the subject of the analysis that refers to the 5 most popular children's YouTube channels in which children participate, and according to the criterion of the largest number of subscribers. The research tried to show the image of the child and childhood in the modern media, analyzing 50 videos and identifying and interpreting the educational-socialization and educational elements, also focusing on the dominant themes and actors of the videos. The results indicate that the contemporary image of children and childhood, on the example of YouTube, shows children as 'little adults' who start their careers in this popular industry at a very early age and through the prism of fun and children's games participate in marketing advertising and earn very high earnings. However, in addition to the aforementioned elements, the analysis shows that the videos also contain educational and socialization elements related to the promotion of prosocial behavior and educational elements related to teaching letters, numbers, animal names, and hygiene habits. Unpacking toys, family outings, outdoor activities, fighting over toys, educational and fun nursery rhymes, and a children's game of buying and selling are recognized as the predominant themes in the videos. In the role of the main actors of all the videos, there are children who play the role of educators and entertainers, in which they are also helped by their parents, whose role, in addition to entertainment, is more directed towards education and socialization.
