They will oversee a panel of more than 40 judges, drawn from across the industry, who will decide the most important annual awards in UK commercial media.
Biggam, whose independent agency was crowned Agency of the Year at the 2015 Media Week Awards, said: "The Media Week Awards are our very own Oscars. They are a chance to forget the daily routine and celebrate the outstanding creativity that our industry is capable of.
"The Media Week Awards have always been a great recognition of hard work, innovation and business results. It’s an honour to help Media Week to identify and reward the very best work in the industry."
Daglish, who was part of the ITV Commercial team that won Sales Team of the Year at the 2013 Media Week Awards, said: "New technologies and consumer attitudes continue to change how we in the media world operate. But, at the heart of every successful campaign remains the craft of the media expert.
"The Media Week Awards is recognition of these craftsmen and craftswomen – the brightest minds and collaborations, the best of the best of the best. It is a great privilege and honour to chair the awards."
Biggam and Daglish also teamed up recently for an advertising campaign to promote the relaunch of Campaign.
Entries for the 2016 Media Week Awards are due to close on 23 June.
The winners will be unveiled at the Media Week Awards dinner, attended by 1,400 guests from across the industry, on 20 October at Grosvenor House on Park Lane in London.
