What is the Biggest Advertising 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 across 112 countries. It is part of the Interpublic network and is a member of the IPG Mediabrands group, which includes Initiative, Magna, Mediabrands Audience Platform, and three other agencies. Deloitte Digital is just beginning to tap into its potential, and the agency has recently been acquiring talent by purchasing San Francisco-based creative store Heat and Swedish agency Acne. At the start of the 21st century, management consulting firms such as PwC Digital and Deloitte Digital began to compete with advertising agencies by placing 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, has been around for more than 120 years - making it one of the oldest advertising agencies in the world.With more than 80 offices around the world, this German communications agency is the only one that has a presence in all 28 EU Member States as well as in economic centers around the world.

In 1985, Martin Sorrell used a listed manufacturer to create what is now the world's leading advertising agency - WPP - with the intention of launching a global marketing company. An advertising agency - also known as a creative agency or ad agency - is a company that specializes in creating, planning, and managing advertising campaigns as well as other forms of promotion and marketing for its clients. This list represents the 50 largest agencies and not networks or groups of agencies such as WPP, Publicis Group, Dentsu Inc., Interpublic, and Omnicom Group.Sorrell continues to point out the major differences between today's data-driven agencies and those that are driven by creativity. This China-based advertising agency focused on brand management became the first Chinese publicly traded company in this field.

None of the larger agencies are actually agencies but rather networks that control many smaller niche companies that can provide specific services to clients.
