Martin Sorrell Urges Advertising Agencies to Adapt as AI Transforms
Advertising agencies help companies create ads and decide where to show them.
Martin Sorrell says artificial intelligence is changing this work quickly.
AI can help make pictures, write copy and plan media faster and more cheaply.
He thinks agencies should charge for results instead of simply charging for time.
He also says most advertising growth is happening online.
Big companies need to use social media and influencers to compete with smaller businesses.
Sorrell believes WPP needs a clearer strategy and stronger leadership.
He disagrees with organizing agencies mainly by creative discipline.
He says organizing them by geography could give clients a more connected service.
Martin Sorrell says AI is reducing the cost and time of creative and media work.
He argues agencies should charge for outcomes and performance rather than hours worked.
Sorrell says digital advertising accounts for $900 billion of the global $1.2 trillion market.
He criticizes WPP’s recent performance and says its leadership lacks a strong strategy.
Sorrell favors geographic consolidation over WPP’s discipline-first restructuring and the Omnicom-IPG merger model.
