Punk is an anti-establishment genre of music that emerged in the mid-1970s and grew to include a large subculture. Punk culture included it's own fashion styles, ideologies, types of dance, film, visual art and literature. Punk's DIY attitude towards music and literature led to a massive growth in zine publishing by the punk community, who seized on the medium of self-publishing. The punk movement was an essential part of zine history and a large segment of the zine community today has at least some roots in punk. Early punk zines included Sniffin' Glue, Punk fanzine, Flipside and Maximum Rock 'N' Roll, later popular punk zines include titles like Punk Planet, Razorcake, Cometbus and Heartattack.
