Disco
Disco was at its most popular in the United States and Europe in the late 1970s and early 1980s. Disco was brought into the mainstream by the hit movie Saturday Night Fever, which was released in 1977. This movie, which starred John Travolta, showed people doing disco dancing. Many radio stations played disco in the late 1970s. By the early 1980s, disco had started to fall out of popularity, and other genres, such as dance, Hi-NRG and post-disco grew in popularity. Nevertheless, disco still exerts an influence on modern day dance music, and still has occasional moments of popularity. Additionally, a different form of disco arose in Europe, known as Euro disco, which obtained some popularity.
