Disco music was a worldwide phenomenon, but its popularity declined in the United States in the late 1970s. On July 12, 1979, an anti-disco protest in Chicago called "Disco Demolition Night" had shown that an angry backlash against disco and its culture had emerged in the United States. In the subsequent months and years, many musical acts associated with disco struggled to get airplay on the radio. A few artists still managed to score disco hits in the early 1980s, but the term "disco" became unfashionable in the new decade and was eventually replaced by "dance music", "dance pop", and other identifiers. Although the production techniques have changed, many successful acts since the 1970s have retained the basic disco beat and mentality, and dance clubs have remained popular. (From Wikipedia)
