I’ve always been fascinated by the evolution of the marketing and advertising industry. Today, I want to take you through the history of marketing agencies on the London Stock Exchange, specifically focusing on their presence in the prestigious FTSE 100 index. It’s a tale of innovation, growth, and adaptation that has shaped the landscape of modern advertising.
The First Marketing Agency to Grace the FTSE
When we talk about the first marketing or advertising agency to be listed on the FTSE, one name stands out: WPP plc. This British multinational communications, advertising, public relations, technology, and commerce holding company has a rich history that dates back to 1985 when it was founded by Martin Sorrell (https://www.wpp.com/about/our-history).
WPP’s journey to the FTSE 100 is nothing short of remarkable. The company started as Wire and Plastic Products, a manufacturer of wire shopping baskets, before Sorrell transformed it into a marketing services company. Through a series of bold acquisitions and strategic moves, WPP quickly grew to become a dominant force in the advertising world.
In 1989, just four years after its founding, WPP made history by becoming the first marketing services company to be listed on the FTSE 100 index. This milestone marked a significant shift in the perception of the advertising industry, elevating it from a creative service to a serious business sector worthy of investor attention.
WPP’s Enduring Presence

Now, you might be wondering, “Is WPP still part of the FTSE 100 today?” The answer is a resounding yes. Not only has WPP maintained its position in the index, but it has also grown to become the world’s largest advertising company as of 2023 (https://www.wpp.com/about).
WPP’s continued presence in the FTSE 100 is a testament to its ability to adapt and thrive in an ever-changing marketing landscape. From traditional advertising to digital marketing, from public relations to e-commerce, WPP has consistently evolved its services to meet the needs of global brands in the 21st century.
The company’s journey hasn’t been without its challenges, of course. The advertising industry has faced numerous disruptions over the years, from the rise of digital media to the impact of global economic crises. Yet, WPP has managed to navigate these turbulent waters, maintaining its position as a leader in the field and a stalwart of the FTSE 100.
Marketing and Advertising Agencies in Today’s FTSE
As we look at the current composition of the FTSE 100, it’s interesting to note that WPP remains the only pure-play marketing and advertising agency in the index. This might seem surprising given the growing importance of marketing in our digital age, but it speaks to the unique position that WPP has carved out for itself.
However, this doesn’t mean that marketing and advertising are underrepresented in the FTSE 100. Many companies in the index have significant marketing operations or provide services that are closely related to the advertising industry. Let’s take a closer look at some of these businesses:
WPP plc
As we’ve discussed, WPP is the giant of the advertising world. Its portfolio includes some of the most recognisable names in the industry, such as Ogilvy, Grey, and VMLY&R. WPP’s services span traditional advertising, public relations, media investment, and market research, making it a one-stop shop for brands looking to make their mark in the global marketplace.
Relx plc
While not strictly an advertising agency, Relx (formerly Reed Elsevier) is a global provider of information-based analytics and decision tools for professional and business customers. Its services include data analytics and digital marketing solutions, which are increasingly important in the modern advertising landscape (www.relx.com).
Informa plc
Informa is a leading international events, digital services and academic knowledge group. While it’s not an advertising agency per se, its events and publishing divisions play a crucial role in B2B marketing for many industries (www.informa.com).
Rightmove plc
As the UK’s largest online real estate portal and property website, Rightmove plays a significant role in property advertising. While it’s not a traditional advertising agency, its platform is a key marketing channel for estate agents and property developers (www.rightmove.co.uk).
Auto Trader Group plc
Similar to Rightmove, Auto Trader is a digital marketplace, but for vehicles. It provides a platform for car dealers to advertise their stock, making it an important player in automotive marketing (plc.autotrader.co.uk).
The Changing Face of Marketing in the FTSE
The composition of marketing-related companies in the FTSE 100 reflects the changing nature of the advertising industry. While traditional agencies like WPP continue to play a crucial role, we’re seeing the rise of platform businesses that facilitate marketing in specific sectors.
This shift is indicative of broader trends in the marketing world. The digital revolution has transformed how brands connect with consumers, leading to the emergence of new types of marketing services and platforms. Companies like Rightmove and Auto Trader, which might not have been considered “marketing” businesses in the traditional sense, are now key players in their respective sectors’ marketing ecosystems.
Moreover, the lines between marketing, technology, and data analytics are becoming increasingly blurred. Companies like Relx, which provide data-driven insights and solutions, are playing an increasingly important role in shaping marketing strategies for businesses across various industries.
The Future of Marketing in the FTSE
As we look to the future, it’s clear that the role of marketing and advertising in the FTSE 100 will continue to evolve. While WPP remains the standard-bearer for traditional advertising agencies, we’re likely to see more companies that facilitate or enable marketing in various forms joining the index.
The rise of artificial intelligence, big data, and personalised marketing is likely to drive further changes in the industry. We might see tech companies with strong marketing capabilities or adtech firms making their way into the FTSE 100 in the coming years.
Furthermore, as sustainability and social responsibility become increasingly important to consumers and investors alike, we may see a greater emphasis on purpose-driven marketing. Companies that can demonstrate their ability to create value while also making a positive impact on society may find themselves rising up the ranks of the FTSE.
Reflections on a Marketing Journey
As I reflect on the journey of marketing and advertising companies in the FTSE 100, I’m struck by how much the industry has changed since WPP first joined the index in 1989. From wire shopping baskets to global digital campaigns, the evolution has been nothing short of remarkable.
Yet, some things remain constant. The need for businesses to communicate effectively with their customers, to build brands that resonate, and to stay ahead of changing consumer trends – these are the foundations upon which companies like WPP have built their success.
As we move forward, I believe we’ll continue to see innovation and adaptation in the marketing world. The companies that can navigate the complex interplay of creativity, technology, and data will be the ones that thrive, both in the marketplace and on the stock exchange.
For investors, marketers, and business leaders alike, keeping an eye on the marketing presence in the FTSE 100 can provide valuable insights into the direction of the industry and the economy as a whole. After all, in our increasingly connected world, the ability to communicate effectively and persuasively is more important than ever.
As we close this exploration of marketing giants in the FTSE, I’m reminded of a quote often attributed to the advertising legend David Ogilvy: “The consumer isn’t a moron; she is your wife.” In today’s world, we might update that to say, “The consumer isn’t a data point; they’re a person with hopes, dreams, and values.” The marketing companies that remember this, that put the human element at the heart of their strategies, are the ones that will continue to shape our world and our stock markets for years to come.
