Today, children are surrounded by the media from an early age, so we can say that the media is part of their upbringing. This paper discusses the impact of the Internet, as a type of media, on speech development in preschool children. Although in the first years of life the media are not necessary for the development of the child, children love children's television programs, video games and other content on the Internet, so it is questionable whether its use has a positive or negative impact on speech development? With the help of literature for clarification, I will try to present the Internet as a medium without which it is almost impossible to imagine life today, the development of speech from birth and the impact of the Internet on speech development from an early age. The impact of the internet can have its advantages but also its disadvantages. With the help of the media, children and young people can easily express themselves in society. Much easier than before. The role of adults is important, as they should enable children to have fun in the media, stimulate their curiosity, research and question the media. Adults in the family also have a responsibility to determine the use of the media, in this case the Internet, appropriate to their age. As children spend more and more time in front of the screen, it is important to know their content and effect. In order to investigate the impact of the Internet on the speech development of preschool children, I conducted a survey that found that parents believe that the Internet can positively affect the language expression of their children, if the content is educational and lacks verbal communication between parents and children. for speech development.
