Through the history of the hip hop movement, there have been several significant figures contributed to its development. The origin of hip hop movement may be traced back to the early 1970s when rap was introduced at block parties in New York City as a specific genre, and DJs started cutting off the beating breaks of funk, soul, and disco songs and expanding them. MCs began to talk between songs, joking and normally interacting with the audience in order to introduce the DJs and to invigorate the crowd. Thus, the new genre began to attract audience and became commercially successful. The American funk group the Sugarhill Gang, through its "Rapper's Delight," made a remarkable contribution to the popularity of hip hop music, and many critics consider this as the earliest hip hop single. This hip hop group, credited with the first ever gold single, ensured the commercial feasibility of the genre, which resulted in the wide-ranging popularity of the rap music.
