Current state of music magazine sector and audience research

My inspiration for my music magazine is 'Kerrang'. The publisher is 'Bauer' and they also produce other music magazines such as 'Mojo' and 'Q'. Kerrang first concentrated on rock and heavy metal, but now covers a more alternative rock and punk genre. Kerrang was first published as a monthly magazine, but now, because of i's increasing sales, is now a weekly magazine. Kerrang has a reputation for following the trend with the latest rock groups. however, in 2003, sales declined when they followed the genre of 'nu-metal', which was a trend that did not last long. After this, Kerrang focused on more alternative rock/punk bands such as My Chemical Romance, and by 2009, Kerrang's weekly sales were over 50100!!
Kerrang's audience is 60% male and 40% females and range from the ages of 16-24. The magazine is aimed at the rock genre and includes alternative bands such as 'Paramore' and 'All Time Low'.
