Psychedelic rock declined towards the end of the 1960s, as bands broke up or moved into new forms of music, including heavy metal music and progressive rock. Like the psychedelic developments of the late 1960s, punk rock and new wave in the 1970s challenged the rock music establishment. At the time, "new wave" was a term used interchangeably with the nascent punk rock explosion. In 1978, journalist Greg Shaw categorized a subset of new wave music as "neo-psychedelia", citing Devo, "to an extent ... first major indication ... [they are the new darling of the new wave press and opinion-makers, yet nothing about it is remotely 'punk'". Shaw wrote that in England, neo-psychedelia was known as "acid punk", noting "self-advertised 'psychedelic punk' band, the Soft Boys, being hotly pursued by several major labels."
