Artrocker magazine is an independent monthly publication, concentrating on music and modern culture, available across the United Kingdom. Before switching to a digital format in 2013, it was stocked in larger branches of newsagents, though its main availability was in music stores. The magazine started life as a weekly email newsletter before evolving into a printed magazine. Issue one featured KaitO on the cover and was released on 4 October 2004. The publication appeared on a bi-weekly basis until November 2007 (issue 72), when the magazine began publication on a monthly basis. Launching its first digital edition in 2010, Artrocker slowly phased out the print issue, with the tablet version outselling the magazine by 2012.
