However, the advertising game has grown more competitive than ever amid online and offline media's evolution.

Being full-service companies, they've been able to scale up and weather market changes. Their teams' varied specializations gave them access to more extensive, equally varied consumer markets.

The world’s largest multi-national marketing and public relations agency to date, WPP’s clientele includes 307 of Fortune Global 500 and all firms belonging to the Dow Jones 30. Several respected creative agencies are part of this conglomerate, including Ogilvy, AKQA, Wunderman Thompson, and VMLY&R. Also, PR firms such as FGS Global, BCW, and Hill+Knowlton Strategies make up this advertising giant. GroupM, a media investment company under its wing, produces over 2 million ad campaigns worth over $60 billion annually through its AI-enhanced and cross-channel optimized subsidiary GroupM Nexus.

The company, which has a 115,000-strong staff spread across over 100 countries, offers communications, experience, commerce, and technology services. Over 33,000 of its employees hold technology partner certifications. WPP won the Most Creative Company award at the 2022 Cannes Lions Festival.

WPP stands for Wire and Plastic Products. The agency was a wire basket and teapot manufacturer when it started in 1971. It evolved into its present status as the industry’s “creative transformation company” when businessman Martin Sorrell and stockbroker Preston Rabl bought a majority stake in the company in 1985 and went into a series of mergers and acquisitions for the next three decades.


2. Deloitte Digital (DD)

Deloitte Digital (DD)

Headquarters: New York

2021 Revenues: $16 billion

  • Advertising, marketing, and commerce (including content, social, and search strategy, digital and physical experience design, AR and VR design, film production, analytics, commerce strategy, and global market entry)

3. Accenture Song

Accenture Song

Headquarters: New York

2022 Revenues: $15.4 billion

Accenture Song represents Accenture’s marketing, creative, design, and technology division. Forty firms have come under its wing since it started as Accenture Interactive in 2009. It may be the youngest player among the older ad “giants” in this list, but CEO David Droga is an industry veteran. The former Saatchi & Saatchi Asia regional creative director and Singapore executive creative director explained that unlike the generic Accenture Interactive, “Song” in the new company name reflects the humanity of its products and services. Moreover, Droga wants the rebranded company to operate outside the “old model” of holding companies to give clients new ways of “making money.”  

Accenture Song explores opportunities in visual effects, AI, and the metaverse to improve customer experiences. Moreover, its services cover business growth and venturing, marketing and digital commerce strategy, product and channel experience creation, platform enablement, campaign activation, brilliant marketing performance, and customer service consulting.

The so-called “big bang” merger happened in 1986, although Batten Co. began operating as early as 1891. The media outlet also manages the DAS Group of Companies and the Communications Consultancy Network. These networks offer brand advertising, media planning, buying services, customer relationship management, public relations, and more.

  • Publicis Media involves member firms handling consumer engagement for clients through performance marketing, analytics, commerce, and investment (Digitas, Starcom, Zenith, Spark Foundry, Performics)
  • Publicis Health supports the business transformation of health and wellness clients (Digitas Health, DiscoveryUSA, Publicis Health Media, Publicis LifeBrands) 

In February 2023, Publicis launched the Epsilon Digital Customer Data Platform (CDP). Aside from being a first-party data solution, the CDP enables marketers to activate campaigns on owned and paid channels in a simple, self-service portal.

Publicis now has a 78,000-member talent pool working from 100 nations. The company name was founder Marcel Bleustein’s idea—he combined the French term for advertising (publicité) and the number six from the firm’s founding year, 1926.

For a second year in a row, IPG is a recipient of Effie U.S. Awards’ Most Effective Holding Company in 2023.

7. Dentsu Inc.

Dentsu Inc.

Headquarters: Tokyo

2022 Revenues: ¥1.1 trillion ($7.76 billion)

Dentsu has expanded its three lines of business—creative, media, and CRM—from Japan to an international network consisting of 750 overseas partners and 160 local ones. Nearly a third of its consolidated net revenue comes from customer transformation and technology or “CT & T,” which includes marketing technology, system integration, customer experience management, and growth strategy. Its leading member agencies promoting growth in CT&T are Merkle, iSiD, and Dentsu Digital.

Dentsu’s roots go back to 1901 when war correspondent Hoshio Mitsunaga established an ad-selling company to support his news agency. He combined the two entities in 1907, calling it Dentsu. Dentsu began opening offices outside Japan in 1959. Its partnerships with America’s Young & Rubicam in 1981 and the UK’s Aegis Group PLC in 2012 further strengthened its global reach. The company shifted to a pure holding-company structure in 2020, changing its name to Dentsu Group Inc., replacing its former trade name Dentsu Inc. In the same year, Dentsu International became the new name of Dentsu Aegis Network Ltd, which handled its foreign operations.

Approximately 69,000 people work at Dentsu and its member companies in 145 nations and regions.


8. Hakuhodo

Hakuhodo

Headquarters: Tokyo

2022 Revenues: ¥895.08 billion ($6.32 billion)

Hakuhodo believes in the “seikatsusha” (living person) approach to viewing customers with unique desires and needs instead of faceless consumers. The company’s data management platform (DMP) allows it to create customized client solutions. At the same time, businesses can integrate the DMP with their databases for deeper customer knowledge and insights into trends. Hakuhodo also performs research and development using AI, big data analytics, and their annual HABIT/ex and Global HABIT surveys. Moreover, it provides data fusion management strategies for information anonymity, behavioral scoring, ID-POS (purchase) data and time-series analysis modeling, and marketing mix modeling.

Advertising space broker Hironao Seki established Hakuhodo in 1895. In 1924, it became a stock company that was incorporated in 1955. Like Dentsu, the company adopted the account executive system in the late 1950s. In 2003, Hakuhodo DY Media Partners Inc. came into existence and became listed on the Tokyo Stock Exchange two years later. The business has over 150 offices in 20 nations and regions.


9. Stagwell Inc.

Stagwell Inc.

Headquarters: New York

2022 Revenues: $2.7 billion

Stagwell Inc. is the new entity that emerged following the 2021 merger between the Stagwell Marketing Group Holdings, founded in 2015, and MDC Partners Inc., founded in 1980. Their capabilities include research and insights, digital transformation, global media and content, creative services, public affairs, and advocacy. The company also hosts the Stagwell Marketing Cloud, which includes real-time consumer search, “comms tech” (to land your message onto your target journalist, influencer, or other audience using AI), media studio (strategy, analytics, and media buying), and advanced platforms (AR, first-party data access for the travel sector, peer-to-peer texting, and in-airport TV).

Founder and CEO Mark Penn is considered the father of modern polling. He established Penn and Schoen in 1975 before becoming Microsoft’s chief strategist in the 1990s and a political pollster a decade later (for Hillary Clinton and Tony Blair). Penn said that MDC’s creative strength was what Stagwell’s data expertise (always-on market intelligence, AI-driven PR SaaS, and global survey) needed to become a new industry force.

The 13,000 employees and 1,250 engineers working for over 70 Stagwell member firms from 34 countries serve 4,000 clients worldwide.


10. Havas Group

Havas Group

Headquarters: Paris

2022 Revenues: €424 million ($463.88 million)

Havas is a marketing company under French communications and entertainment leader Vivendi, which recorded €9.6 billion ($10.48 billion) in revenues for 2022. The over 300 agencies under the Havas umbrella offer business consultancy (including analytics), brand consultancy (design, sponsorship, and events, both live and digital), creative services, media (including paid media and consumer intelligence), production and content at scale, customer experience, PR, and health and wellness communications. 

The company’s three business units are Havas Creative, Havas Media (Havas Media and Arena Media, which handle mobile solutions, outdoor advertising, experiential marketing, and sports), and Havas Health & You. In 2020, Havas Media launched Havas Market, its full-service eCommerce offering.

Havas Group came from Bureau Havas, set up by Charles-Louis Havas in 1835. It became the world’s first international news agency, translating news reports from French and foreign papers for distribution in France and the overseas press. The founder’s sons developed the advertising side of the business from the 1850s onwards. In the 1940s, Agence Havas reorganized its news section as Agence France-Presse after the Nazis left France and was under government control for a time. It became privatized in 1987. Vivendi acquired Havas in 2017.

The 22,000-plus people working for Havas Group agencies belong to 70 so-called “Havas Villages”—or teams in which they can collaborate and learn from each other—in over 100 countries.

Frequently Asked Questions

What are the pros and cons of hiring an ad agency?

Outsourcing your advertising activities has its benefits and drawbacks. Here are some of them:

  • Wider market reach
  • Campaign performance tracking and measurement

      • Study your company's requirements to determine the project’s scope and completion target.
      • Know your company's budget for the project.
      • Research and check company reviews. Check their track record, portfolio, references, and pricing. Look for an agency that understands your brand's goals and needs.
      • Set expectations early.
      • Gauge their communication style (as the agency must provide sufficient engagement throughout the project)
      • Leave room for new ideas and routines.
      • Ask how they determine to price and deliver their performance reporting and data analysis.
