He was the "Wizard of WPP." For thirty-three years, Sir Martin Sorrell didn't just run a company; he lived it. Every acquisition, every client dinner, and every late-night flight across the globe built a machine that eventually controlled roughly one-third of the world’s advertising. But then, in April 2018, it all came crashing down in a messy, public, and surprisingly abrupt exit. If you’re looking into Sir Martin Sorrell WPP history, you aren't just looking at a corporate timeline. You’re looking at a cautionary tale of how a wire-and-plastic manufacturer became a $20 billion behemoth before the foundation cracked.
Sorrell is a polarizing figure. To some, he’s the ultimate entrepreneur who understood the "mathematics of advertising" better than the creatives ever could. To others, he was a micro-manager whose iron grip eventually became a liability.
How a Shopping Basket Company Conquered Madison Avenue
The story of Sir Martin Sorrell WPP starts in 1985. It’s almost funny now, but WPP stood for Wire and Plastic Products. They made wire shopping baskets. Sorrell, fresh off a stint as the "third brother" at Saatchi & Saatchi, was looking for a shell company to build his own marketing empire. He bought a nearly 30% stake in this tiny manufacturer for about $250,000.
He didn't want to make baskets. He wanted to buy the world.
The first massive shock to the industry came in 1987 when Sorrell launched a hostile takeover of J. Walter Thompson (JWT). It was unheard of. A British firm, led by a "bean counter," was swallowing a legendary American agency. He didn't stop there. Two years later, he grabbed Ogilvy & Mather for $864 million. David Ogilvy famously called Sorrell an "odious little jerk" before eventually relenting and becoming WPP’s chairman. This era defined the Sorrell playbook: buy, integrate, and squeeze out efficiencies.
By the early 2000s, WPP was a monster. It owned Young & Rubicam, Grey, GroupM, and Kantar. It was the holding company model perfected. If you were a global brand like Ford or Unilever, you basically had to work with WPP because they owned the talent, the data, and the media buying power.

The Micro-Manager in Chief
There’s a famous story about Sorrell’s work ethic. He reportedly checked his Blackberry every few minutes, responding to emails at 3:00 AM from whatever time zone he happened to be in. He knew the numbers of every sub-agency. Honestly, it was exhausting just watching him. This wasn't a CEO who sat in a glass office and pondered "synergy." He was in the weeds.
But that’s where the friction started.
As the digital age arrived, the "holding company" model started to look a bit dusty. Facebook and Google began eating the lunch of traditional agencies. Clients started questioning why they were paying massive retainers to multiple WPP agencies that often competed with each other. Sorrell tried to fix this with "horizontality"—the idea that different WPP agencies would work together for one client. It sounds good on paper. In practice? It was a political nightmare of turf wars and ego.
The 2018 Exit: What Most People Get Wrong
When Sorrell left WPP in April 2018, the headlines were explosive. An investigation into "personal misconduct" and the "misuse of company assets" had been launched by the board. Sorrell denied any wrongdoing, and the specific details were never fully made public, though rumors about expenses and personal conduct swirled for months.
It felt like a Shakespearean tragedy. The man who built the house was being kicked out of the front door.

The board's investigation focused on whether company funds were used for personal expenses. Sorrell eventually resigned, but he didn't go quietly. He didn't even take a non-compete. That was the board’s biggest mistake. Within weeks, he had formed S4 Capital. He essentially started over, but this time, he was digital-first. He bought MediaMonks, then MightyHive. He was competing directly against the very giant he spent three decades building.
Why the WPP Model Struggled Post-Sorrell
After Sorrell left, Mark Read took the reins. Read had a massive job: simplify. WPP was a tangled web of hundreds of agencies. Under Sorrell, it was a sprawling collection of fiefdoms. Read started merging them—JWT and Wunderman became Wunderman Thompson; VML and Y&R became VMLY&R.
The industry shifted. Basically, the "big ad" era was dying.
- Big data became the new oil.
- Creative work was being brought in-house by brands like Apple and Netflix.
- Consulting firms like Accenture Interactive started stealing high-level strategy work.
Sorrell’s WPP was built on the idea that scale was everything. If you were the biggest, you won. But in the 2020s, agility became more important than size. S4 Capital, Sorrell’s new venture, focused on "holy trinity" of data, content, and digital media. It was a leaner, faster version of what he’d built before.
The Financial Legacy and the Payouts
You can't talk about Sir Martin Sorrell WPP without talking about the money. Sorrell was one of the highest-paid CEOs in the UK for years. In 2015, his pay package was roughly £70 million. Shareholders were furious. There were constant "say on pay" revolts at annual meetings.

The argument from the board was always: "Look at the share price." And for a long time, it worked. Between 2009 and 2017, WPP shares went on a tear. But when the growth slowed, the high pay became a target. It’s a classic business lesson. People forgive a lot when the stock is up, but the moment things level off, everyone starts looking at the receipts.
Is the Holding Company Model Dead?
Not quite. WPP is still a massive force. It still wins huge accounts—like the massive Coca-Cola "OpenX" win a few years back. But it’s a different beast now. It’s less about Sorrell’s personality and more about technological integration.
Interestingly, Sorrell’s S4 Capital has hit its own speed bumps recently. The stock price there has struggled as the tech sector cooled. It turns out that even the "Wizard" can't always outrun market cycles.
Lessons From the Sorrell Era
If you're an entrepreneur or a business leader, the WPP story offers some pretty gritty insights. First, your biggest strength—in Sorrell’s case, his relentless control—eventually becomes your biggest weakness. You can't scale a multi-billion dollar company as a one-man show forever.
Second, the "buy and build" strategy requires a pivot to "integrate and innovate" much sooner than most people think. WPP stayed in "buy" mode for too long. By the time they tried to integrate, the culture was too fragmented.
Actionable Insights for Navigating the Modern Ad Landscape:
- Prioritize Agility Over Scale: If you’re hiring an agency or building a team, don't just look for the biggest name. Look for the one that can pivot their tech stack in six months, not six years.
- Beware the "Founder Trap": Succession planning isn't just a HR box to tick. WPP’s lack of a clear, public successor made Sorrell’s exit much more damaging to the stock price than it needed to be.
- Data is Non-Negotiable: The reason Sorrell’s S4 Capital gained traction so fast was its focus on first-party data. If your marketing strategy doesn't own its data, you're just renting space on someone else's platform.
- Cultural Integration Matters: Merging two agencies isn't just about combining balance sheets. It's about making sure the "creatives" and the "data people" actually speak the same language. WPP’s later years were plagued by internal friction that slowed down client delivery.
Sir Martin Sorrell's time at WPP changed the way we think about advertising. He turned it into a global, professionalized service industry. Whether you love him or hate him, the landscape of Madison Avenue—and the London agencies that challenged it—would be unrecognizable without him. The empire still stands, but it looks a lot different in the rearview mirror.
