Hip Hop TV :

Hip hop is a cultural movement which developed in New York City in the 1970s primarily among African Americans and Latino Americans.[1][2] Hip Hop's four main elements are Mc'ing (often called rapping), DJing, graffiti writing, and breakdancing. Other elements include beatboxing, hip hop fashion, and slang. Since first emerging in the Bronx, the lifestyle of hip hop culture has spread around the world.[3]

When hip hop music began to emerge, it was based around DJs who created rhythmic beats by looping breaks (smalls portions of songs emphasizing a percussive pattern) on two turntables. This was later accompanied by "rapping" (a rhythmic style of chanting). An original form of dancing, and particular styles of dress, arose among followers of this new music. These elements experienced considerable refinement and development over the course of the history of the culture.
