A semi-structured interview form was used as a data collection tool in the research. The content analysis technique was used to analyze the data obtained in the research. As a result of the research, it was determined that the multimedia devices that children spent most time on were televisions, smartphones and tablets. Children preferred to use multimedia mostly for fun and games. The vast majority of parents thought that adult supervision was needed when children spent time using multimedia devices.
