the watershed moment in British punk's transformation into a major media phenomenon, even as some stores refused to stock the records and radio airplay was hard to come by. In May 1977, the Sex Pistols achieved new heights of controversy (and number two on the singles chart) with a song that referenced Queen Elizabeth II, "God Save the Queen", during her Silver Jubilee. For the most part, punk took root in local scenes that tended to reject association with the mainstream. An associated punk subculture emerged, expressing youthful rebellion and characterized by distinctive clothing styles and a variety of anti-authoritarian ideologies. By the beginning of the 1980s, faster, more aggressive styles such as hardcore and Oi! had become the predominant mode of punk rock. This has resulted in several evolved strains of hardcore punk, such as D-beat (a distortion-heavy subgenre influenced by the UK band Discharge), anarcho-punk (such as Crass), grindcore (such as Napalm Death), and crust punk. Musicians identifying with or inspired by punk also pursued a broad range of other variations, giving rise to New wave, post-punk and the alternative rock movement.

Punk rock had attracted devotees from the art and collegiate world and soon bands sporting a more literate, arty approach, such as Talking Heads and Devo began to infiltrate the punk scene; in some quarters the description "new wave" began to be used to differentiate these less overtly punk bands. Record executives, who had been mostly mystified by the punk movement, recognized the potential of the more accessible new wave acts and began aggressively signing and marketing any band that could claim a remote connection to punk or new wave. Many of these bands, such as the Cars and the Go-Go's can be seen as pop bands marketed as new wave; other existing acts, including the Police, the Pretenders and Elvis Costello, used the new wave movement as the springboard for relatively long and critically successful careers, while "skinny tie" bands exemplified by the Knack, or the photogenic Blondie, began as punk acts and moved into more commercial territory.
