Omar Oakes and columnist Nick Manning have a wide-ranging conversation about the recent ANA report into media agency reselling ("principal-based media"), where media agencies buy media at one price and resell it to clients at an undisclosed higher price – and why it's important.

This is an epic conversation that delves into why advertising is no longer well-integrated with content, why there is a talent drain from the industry, why it may be "inevitable" that major ad agency groups are broken up and what Nick is planning through the 'Who Cares" movement with Brian Jacobs.
