It is the question that British writers and commissioners perennially ask: which system works best – the UK’s single voice or the US’s showrunner model?

Former head of BBC Worldwide Productions turned independent producer Jane Tranter tried to answer this key question with a panel of writers, who outlined their experiences to see how they compared.

She pointed out that, during her seven years in the US, it was not a subject the industry there generally debated openly.

The digital revolution will be televised,” argued ­Viacom chief Philippe Dauman in an upbeat address to the RTS Convention. Twelve months after the US media giant bought Channel 5 for £450m, Dauman offered a positive “end-of-term report on our first year as a British public service broadcaster”.

“Today, I am pleased to reaffirm our commitment to upholding the rights and responsibilities that entails. We pledged that we would increase investment and original creative content – we have, and will continue to do so.”

Philippe Dauman, Chief Executive of Viacom, the media empire created by nonagenarian Sumner Redstone, has been called many things in his long Viacom career.

One is "dauphin", marking both his succession potential and the fact that he is French-born. Although he has lived almost all of his life in the US, Dauman is a fluent French speaker.

He is "an iron fist in a velvet glove" according to Sir Martin Sorrell, Chief Executive of WPP. The New York Times summed him up as "The man who would be Redstone".
