This year's panel includes Kelly Williams, group commercial director, ITV, Stuart Mays, director of commercial strategy, Global Radio, Pedro Avery, chief executive, Arena, Paul Frampton, chief executive, Havas Media UK, Karen Stacey, broadcast sales director, Bauer Media and Ann Wixley, creative director, OMD UK. The licensing hours of the Grosvenor Hotel have been extended by two hours this evening, to aid the celebration and both a live band and DJs have been booked as part of the after-show entertainment.
Co-chair of this year’s judging panel, Linda Grant, managing director of Metro, called them "a hugely important event in the media calendar", and "an opportunity to celebrate the breadth and depth of talent within our industry".
Steve Hatch, chief executive of MEC and fellow co-chair of judges, added: "What a privilege it has been to co-chair the Media Week Awards in a year that was a tsunami of a high watermark.
"The judges wrestled and rowed for hours in selecting this year’s winners, with the creative thinking and innovation nothing short of inspiring and matched only by the keen spirit of collaboration of the very best work."
Top-tier sponsors at Media Week Awards 2013 include Metro, ShortList Media, NeverUnderDressed, OK! Magazine, Spotify, BrightRoll, GetMeMedia, TubeMogul and Undertone.
