The latest issue of the magazine, which went on sale on 27 October, included advertorial content from Mattel to promote its Barbie, Monster High, and Girl Tech brands.

The magazine has been published since June 2000 while ABC sales from January to June in 2010 are up 10% on last year.

Alison David, commercial director at Egmont UK, said: "We're very pleased with the growing interest that brands are showing for this property, not just from the key players, but also from non-traditional brands eager to access a market of passionate and committed consumers."
