The two links here give a way in to the website of Publishing House 'Bauer Media'.
This link connects to a page with links to all their magazine tiles. there is also a clear table showing how many of the titles are multi-platform, illustrating Crossmedia synergy (eg Kerrang! has the same design, brand identity and content values on several media platforms including magazine, radio, digital TV and internet)
This link goes directly to the Kerrang! page and you will see a brief concept summary, platforms and a short target audience profile. these pages exist for every title that Bauer publishes.
It is interesting to note that all Bauer's music magazines are found in the 'Men's Entertainment' section. Did you notice such a gender bias in reading them?
