The media, as an integral part of adult life, also affects children and their development and upbringing. This final paper mostly deals with the impact of television and television content on children. Special emphasis is placed on animated film which is considered to be the biggest children’s source of leisure entertainment. Although it can have a variety of negative effects on children, if properly dosed and used it has a greatly positive effect on a child’s development. This is especially true of the communication development that this paper explores. The paper briefly explains how animated film is made and what types and techniques of animation exist. In addition, the history of animated film in Croatia was presented, and a short biography of Walt Disney, the world's largest creator of animated film in the world, was given. Definitions of communication and its division are discussed in detail. Children's speech and communication development is also covered, and the positive and negative influences of animated films are mentioned accordingly. When we talk about media influence, the key role is played by parents, but also by educators, because children spend most of their time in kindergarten. The importance of parental intervention is that children have difficulty recognizing the imaginary and real world and this can cause problems interacting with other peers, especially if the child inserts violent content from the imaginary world they saw in an animated film that was not appropriate for him.
