"COVID basically has accelerated the digital transformation at the consumer level, at the media level... and then last but not least at the enterprise level."

In this special episode of the Mumbrellacast, Mumbrella founder Tim Burrowes chats with S4 Capital founder and executive chairman, Sir Martin Sorrell.

Up for discussion is Sir Martin's outlook on the economic climate, why the 'growth' model of S4 Capital outstrips those of traditional holding companies, how WPP is cannibalising itself, and the legacy of David Ogilvy.

Sir Martin reflects on previous economic crises, offers his views on whether the 'quadrennial effect' of the Olympics and US election on marketing spend will actually take place in 2021, and explains why he is "quite bullish about next year".

He also dives into holding group models; critiquing WPP's recent mergers of Wunderman and JWT, and Y&R with VML, analysing why traditional models need to be dismantled, and explaining why S4 Capital's growth strategy is built for this era.
