The genre coincided with the mid-1960s economic boom that allowed record labels to allocate more creative control to their artists, as well as the new journalistic division between "pop" and "rock" that lent generic significance to both terms. Prog saw a high level of popularity in the early-to-mid-1970s, but faded soon after. Conventional wisdom holds that the rise of punk rock caused this, but several more factors contributed to the decline. Music critics, who often labelled the concepts as "pretentious" and the sounds as "pompous" and "overblown", tended to be hostile towards the genre or to completely ignore it. After the late 1970s, progressive rock fragmented in numerous forms. Some bands achieved commercial success well into the 1980s (albeit with changed lineups and more compact song structures) or crossed into symphonic pop, arena rock, or new wave.
