Hip-hop music originated in the 1970s in the African American and Latino communities in New York. It began as a mixture of spoken words and jazz but later incorporated rapping lyrics performed over beats. In the 1980s, hip-hop grew significantly with more labels and became popular worldwide. However, violence between rival artists brought negative attention to the genre. Famous feuds like the East Coast-West Coast rivalry led to the deaths of Notorious B.I.G. and Tupac. While some artists promote violence, many argue hip-hop's real intention is not to promote this and certain artists steer clear of stereotypical subjects.
