Blaxploitation is a film genre that emerged in the United States circa 1971 when many exploitation films were made specifically (and perhaps exclusively) for an audience of urban black people; the word itself is a portmanteau of the words "black" and "exploitation". Blaxploitation films were the first to feature soundtracks of funk and soul music. These films starred primarily black actors. Variety magazine credited Sweet Sweetback's Baadasssss Song, released in 1971, with the invention of the blaxploitation genre. Others argue that the Hollywood-financed film Shaft, also released in 1971, is closer to being blaxploitation, and thus is more likely to have begun the genre
