Hip hop began in 1974 in the Bronx, New York and is comprised of four main elements: emceeing, deejaying, graffiti, and breakdancing. Some of the founding fathers of hip hop include King Tim III, Sugar Hill Gang, Big Bank Hank, and Master Gee. There are three main subgenres of hip hop: gangsta rap which reflects inner-city violence, conscience rap which creates social awareness, and commercial rap which is made for parties and promoting albums. Hip hop has evolved over time and now debates content differences between current and past female artists as well as changes in slang usage.
