There are some advertisements which children look at barely blinking and they are unable to look away. There are also products that children must have. All this is not a coincidence. Marketing experts for advertising work together with psychologists, sociologists and experts on children's behavior to draw the interest of children to trademarks in the easiest and fastest way. They use a variety of ways to communicate with their targeted groups and to convey them the desired message. They all want a place in the head of a child so that the child chooses exactly their product. A profession with high-tech devices is constantly testing and monitoring children to find a certain structure of characters, colors and music that children cannot resist. The influence of media on children can be positive, but it can also be negative. Children represent the most sensitive group of consumers, because of that it should be studied how marketing activities affect them and to what extent. The media is a source of knowledge, but it is also a source of other useful information. Various educational programs can have a positive influence on the development and further education of children. Likewise, it raises the question of the negative influence of advertising on children's development. Advertisements can be a source of a great deal of sadness and disappointment but also frustration for both children and youth.
