Seo Taiji and Boys acted as an instrument of change within Korea, challenging censorship laws as well as the television networks hegemony over the music market. In 1995 the Korean Broadcasting Ethics Committee demanded that Seo Taiji and Boys change the lyrics for "Shidae Yugam." This incited protests and resulted in the abolishment of music pre-censorship in Korea. Seo Taiji also did not have to rely on television networks due to the fact that he owned his own studio. This autonomy allowed Seo to bring subcultures in Korea, such as heavy metal, to the forefront of popular culture and challenge pervasive social norms. The band's independent success diminished the power of the television networks to dictate which artists appeared on shows, and gave rise to the influence of record labels and talent agencies. Such companies led to the formation of bands such as H.O.T., Sechs Kies, Uptown, and Shinhwa.
