Musically, hip hop was started by DJ Kool Herc. On moving to the South Bronx, New York from Jamaica Herc brought a style of DJing previously heard on Jamaica's sound systems. Herc found reggae to be unpopular and began to play funk, progressing to extending the drum breaks by using two copies. This new style became popular with dancers who were known as Break Boys or B Boys, later to be called breakdancers. The extended drum breaks also created room for the DJ and, later, emcees to rap. The supposed four elements of hip hop only really came together when hip hop was sold to the wider public as a "new thing". This happened from 1979 with the release of Rappers Delight by The Sugarhill Gang. The definitive written history of the birth of hip hop is still David Toop's Rapattack.
