Punk music originated in 1970s New York and provided both a musical and cultural impact. While initially seen as just an aggressive music style, punk created a community and ideals of resisting social norms and promoting a DIY ethic. Punk encouraged participation from groups typically excluded from rock music and taught about social issues. This DIY ethic was key as punk bands had to promote and produce their own music without label support. Punk spread this DIY knowledge through zines and instructions, promoting the idea that anyone could start a band and make music.
