Ros Atkins on some of the biggest media stories this week. As the BBC loses TV rights to the Boat Race – we talk to Siobhan Cassidy Chair of the Boat Race Company and Pete Andrews, Head of Sport at Channel 4 which will now broadcast the annual event. We profile the tech billionaire Larry Ellison – as he steps further into the media world - with Telegraph journalist James Warrington. We'll look at the routes that conspiracy theories take through the media ecosystem with Dr Robert Topinka from Birkbeck University and the broadcaster and author Dr Matthew Sweet. We hear why online content creators teaming up with broadcasters can sometimes be a difficult working relationship with Ben Doyle, co-founder of After Party Studios and Natalie Fahy Editor of the Nottinghamshire Post and its online arm Nottinghamshire Live tells us about their legal challenge to Reform UK after they stopped speaking to their reporters, sending them press releases and inviting them to events.
