Punk was a movement in late 1970s America and Britain that attacked dominant modes of production in music, fashion, and graphic design through negation and refusal. It critiqued rock music and mass culture for promoting passivity and conformity. Punk demanded more authentic experiences and alternative communities. While the first wave was soon appropriated, it inspired related postpunk movements and challenged societal decline and problems ignored by the mainstream. Punk promoted a do-it-yourself ethos and cultural resistance through self-created politics, worlds, and culture rather than just consuming what others produced.
