Why is principal-based media buying so controversial?

Season 4, Ep. 34

Principal-based media buying, which includes inventory media and proprietary media, has become a key practice for large agency groups, but it remains opaque, with finance trails and pricing structures largely in the dark. 


In March this year, ISBA updated its media services framework calling out media agencies for lack of transparency and "non-compliance", which it said has been leading to "tensions" between advertisers and agencies. The IPA hit back at ISBA for suggesting "systemic malpractice" in principal-based media and painting “a misleading picture of how agencies operate”, serving "only to perpetuate the myth that agencies are acting against the interests of their clients”.


In this episode, Campaign's editorial team discuss why this topic is so controversial, shedding light on concerns that exist and the reasons that it remains so obscure. Hosted by tech editor Lucy Shelley, the chat features UK editor-in-chief Gideon Spanier, UK editor Maisie McCabe and media editor Beau Jackson.

  • 47. What makes an ad long-lasting?

    28:19||Season 4, Ep. 47
    Campaign asked this year’s A List cohort to name their favourite TV ad ahead of the upcoming 70th anniversary of commercial television. Guinness “Surfer” by AMV BBDO came out top.One trend that emerged from the choices was that many of the most popular ads were more than 25 years old. Armed with this finding, Campaign reporter Eszter Gurbicz wrote a feature exploring the industry’s love of old ads.This episode of the Campaign Podcast dissects the qualities that make ads stick in peoples’ minds and shares the industry’s view on whether there is any recent work that will be talked about in years to come.Deputy editor Gemma Charles hosts the episode which features editor Maisie McCabe and creativity and culture editor Gurjit Degun alongside Gurbicz.Further reading:A Listers on their favourite TV ads of all timeAre we at the start of a new era of advertising awards?Channel 4 and L’Oreal Paris scoop Film Lions Grands PrixMy Campaign: the making of Guinness ‘Surfer’Ads mentioned in the show include:The Martin Agency's Quiznos subs’ rats (chosen by Mother's Felix Richter) DDB Chicago's Bud Light "Real men of genius: really bad toupee wearer" (chosen by TheOr's Charlene Chandrasekaran)AMV BBDO's Guinness "Dreamer" BBH London's "Three little pigs" for The Guardian

  • 46. What is WPP Media?

    32:34||Season 4, Ep. 46
    Group M, the world's largest media buying group, has undergone a titanic course correction and "simplification", re-emerging as WPP Media. While the destination "makes sense", according to Campaign's editor-in-chief Gideon Spanier, the reorganisation is coming at a huge cost to those that work there.In February this year, The Campaign Podcast asked 'What is Group M?' and in the three months since, the group has merged agency brands into a single P&L, got rid of agency specific jobs titles and begun making roles redundant around the world. More recently, WPP's chief executive Mark Read announced on Monday (9 June) he was stepping down.In this episode, Campaign's editorial team ask a simple question and dig deeper into why WPP has made the change, what will happen to the individual agencies within it, and whether it really is "simpler".Tech editor Lucy Shelley hosts the episode which features Spanier alongside media editor Beau Jackson and deputy media editor Shauna Lewis.Further reading:‘Something’s gone horribly wrong’: new chair faces calls to ‘fix’ WPP at AGMWPP launches data solution Open Intelligence'We know that we have to be simpler': Brian Lesser lays out Group M plansGroup M axes global agency CEO roles in major centralisation push
