As artificial intelligence dominated conversations across Cannes Lions, Sir Martin Sorrell believes the industry is paying attention to the wrong problem.
Speaking to Communicate, the S4 Capital Group Executive Chairman argued that while much of the discussion has centred on AI’s impact on creativity, the real disruption is unfolding elsewhere.
“Cannes looking at the wrong thing, and they’re looking at the impact of AI on the human creativity, and they should be looking at it, the impact on media planning and buying.”
While AI is raising the overall standard of creative output, Sorrell said human creativity will remain the key differentiator for brands as marketers increasingly have access to the same technology.
He believes the more significant shift will come from the changing economics of media, as digital platforms continue to consolidate their dominance and agencies face growing pressure to adapt.
Rejecting the long-standing narrative of media fragmentation, Sorrell said:
“Well, it’s not media fragmentation. I think that’s nonsense. It’s media concentration.”
He pointed to the growing dominance of Google, Meta, Amazon and TikTok, arguing that the industry’s future will be shaped by platform concentration, automation and greater transparency in media trading.
As advertisers demand more visibility into where their budgets are spent, Sorrell believes agencies will have little choice but to embrace a more open operating model.
“We’re going to have to be transparently transparent.”
He also expects digital advertising to continue gaining share, forecasting that it will account for around 80 per cent of global advertising spend by 2030.
Discussing the Middle East, Sorrell acknowledged that geopolitical tensions have temporarily slowed momentum but remains optimistic about the region’s long-term outlook, particularly as businesses accelerate AI adoption.
His advice to marketers was simple: be brave and embrace transformation before competitive pressure forces the issue.
As he put it: “People don’t change when, when they have the ability to change, they only change when they’re forced to change.”
Looking beyond today’s AI conversation, Sorrell suggested an even bigger technological shift may already be on the horizon.
“If we think AI is disrupting our industry, which it is, stand by for quantum.”
