They are often improvisational and social in nature, encouraging interaction and contact with the spectators and the other dancers.Street dance is also commonly used specifically for the many hip hop and funk dance styles that began appearing in the United States in the 1970s, and are still alive and evolving within hip hop culture today: breakdance, popping, locking, hip hop new style, house dance and electro dance. These dances are popular as a form of physical exercise, an art form, and for competition, and are today practiced both at dance studios and other spaces.
