When did rap music become famous?

The exact date that rap music became famous is difficult to pinpoint, as its rise to popularity was a gradual process that occurred over several years. However, a significant moment in the history of rap music was the release of the song "Rapper's Delight" by the Sugarhill Gang in 1979. This song is widely considered to be the first commercially successful rap song, and it helped to bring rap music to a wider audience. In the years that followed, other rap artists such as Run-DMC, LL Cool J, and Public Enemy gained popularity, and rap music became an increasingly prominent genre in the global music industry.
