James Papworth, marketing director at the PPA, said: "The PPA Ad Awards celebrate the strategic thinking, creativity and planning behind the best-executed advertising campaigns across magazine brands and their multiple channels.
"If you plan, produce or invest in advertising which appears in magazine branded environments, in any form, then these are the awards for you."

Nick Heales, head of press at UM, said: "The PPA awards are tremendously valuable to the magazine marketplace, and continue to showcase magazine brands' breadth and innovation across all their touch-points.
"From an agency and client point of view it’s obviously also fantastic to be picked from your peers as a winner."
Charlotte Goddard, associate director at MediaCom, added: 'It was great to attend the PPA Awards in 2013, an event I now look forward to every year.
"It's a way for us to celebrate the amazing versatility of magazine brands, and the creativity that exists within this medium.
