Abstract: The emergence of idols in music industries, especially recently in South Korea, has led to an increase in the number of fans from around the world, especially among teenagers. The popularity of these idols is also due to the influence of social media reporting on their performances, way of life and daily activities, which covers both positive and negative news. In this research, we develop mathematical models to analyze the impact of media on the idols’ popularity using a statistical approach. To apply the models, we collect data from Google Trends for searching statistics graphs that display the popularity of the Korean idols BTS and EXO, and the American idols Taylor Swift and Selena Gomez. We observe the effect of negative and positive news on the popularity of these Eastern and Western idols. It was expected that positive news would increase the number of fanatical fans while negative news would make the fans become bored with the idol quickly. The results show that negative news about Korean idols can reduce their popularity, but on the contrary, negative news about the American idols does not affect their popularity.
