K-Pop has become popular for several key reasons: 1) It replaced J-Pop and J-Rock as the dominant Asian music genre after Japan's music industry became focused only on the domestic market. 2) South Korea learned from Japan's success with J-Pop and invested billions of dollars over many years into cultivating a large K-Pop industry with widespread appeal. 3) Korean culture has proven more relatable to international audiences compared to Japanese culture. This strategic investment and cultural alignment have led K-Pop to achieve global popularity through hard work rather than by accident.
