Through its history, the United Kingdom has been a major exporter and source of musical innovation in the modern and contemporary eras, drawing its cultural basis from the history of the United Kingdom, from church music, from Western culture and from the ancient and traditional folk music and instrumentation of England, Scotland, Northern Ireland and Wales. In the 20th century, influences from the music of the United States became most dominant in popular music. This led to the explosion of the British Invasion, while subsequent notable movements in British music include the New Wave of British Heavy Metal and Britpop. The United Kingdom has one of the world's largest music industries today, with many British musicians having had an impact on modern music.
