Hip hop music (or rap music) is a style of popular music which came into existence in roughly the mid '70s but became a large part of modern day pop culture in the late '80s. It consists of two main components: rapping (MCing) and DJing. Along with breakdancing and graffiti, these compose the four elements of hip hop, a cultural movement that was initiated by inner-city youth, mostly African Americans in New York City, in the early 1970s.
