What's the biggest agency in the world?

WPP is the world's largest advertising company in terms of revenue and employs around 190,000 people in 3,000 offices in 112 countries. The agency is part of the Interpublic network and is a member of the IPG Mediabrands group with Initiative, Magna, Mediabrands Audience Platform and three other agencies. Deloitte Digital is only scratching the surface of its capabilities, and the agency continues to buy talent recently by acquiring the San Francisco-based creative store Heat and the Swedish agency Acne. At the beginning of the 21st century, management consulting firms such as PwC Digital and Deloitte Digital began competing with advertising agencies with an emphasis on data analysis.

The table below combines the most popular digital marketing agencies based on Clutch and Agency Spotter rankings. MEC, the fourth largest agency of WPP GroupM, is a leading media agency with clients such as Vodafone, Netflix, Paramount Pictures, Marriott, Chanel, GE and Xerox. Asatsu-DK is a Japanese advertising agency and the third largest agency in Japan after Dentsu and Hakuhodo. Dentsu is Japan's largest advertising agency and, together with its biggest competitor, Hakuhodo, is more than 120 years old, making it one of the oldest advertising agencies in the world.

With more than 80 offices around the world, the German communications agency is the only agency that is present in all 28 EU Member States and in economic centers around the world. In 1985, Martin Sorrell, intending to launch a global marketing company, used the listed manufacturer to create what is now the world's leading advertising agency. An advertising agency, often known as a creative agency or advertising agency, is a company dedicated to creating, planning and managing advertising, and sometimes other forms of promotion and marketing for its clients. This list represents the 50 largest agencies and not the networks or groups of agencies such as WPP, Publicis Group, Dentsu Inc, Interpublic and Omnicom Group.

Sorrell continues to point out the big difference between the world of creative-driven agencies and today's world of data-driven agencies. This China-based advertising agency focused on brand management became the first Chinese publicly traded company in the field. None of the larger agencies are really agencies, but rather networks that control many smaller niche companies that can deliver specific jobs to clients.
