Kerrang magazine

After looking into Rocksound, I decided to look into another popular rock magazine that I read.
I looked into Kerrang's publishing company, which happens to be Bauer.

Bauer Media connects and engages 19 million consumers every week with the most influential brands in the UK.
They have more than eighty influential media brands spanning a wide range of interests, including heat, GRAZIA, Closer, MCN, FHM, Parker's, MATCH, Magic 105.4, Kiss 100, Kerrang!, 4Music and the Big City Network, their group of twenty local radio stations.
The value of our in-depth understanding of these audiences is reflected in our unrivalled research initiatives. Bauer Media is in a unique position to be able to deliver groundbreaking consumer insight to media professionals, having more market leading brands across a wider breadth of markets than any other media owner.

The Inside
‘The Inside’ is Bauer Media’s unique research panel designed to understand today’s consumers. Launched in November 2006, The Inside’s bespoke research data offers a greater understanding of consumer behaviour and tracks consumer trends as they emerge.
The panel’s 10,000 + members, aged 16 years and over, have been recruited from a wide range of Bauer Media’s brands including FHM, heat, more, Kerrang!, Kiss, Magic 105.4, Empire and GRAZIA.

Unfortunately I can't access this information as Bauer privacy states it is private information. There must be some truth in their research though because Bauer publish some of the best selling brands.
