The WPP Group, based in London, is the world's largest advertising company.
Advertising is an incredibly lucrative industry.An advertising company can be defined as a company that creates, manages, and plans all aspects of a client’s advertising. An advertising company may specialize in a specific area or can be a full-service company that offers public relation services. There are three types of advertising agencies; Above the Line, Below the Line, and Through the Line. ATL are large companies that handle prime account and create national and international advertising campaigns for the clients. BTL handle smaller media placement while THL is a blend of ABL and BTL. Here are the largest advertising companies worldwide.
The London based giant WPP toppled Omnicom Group in 2008 and has since become not only the largest marketing group but also the most revenue generating advertising company. It has an executive office in Dublin and owns various advertising, public relation, and media research networks. WPP owns the some of the largest marketing agencies in the world, namely Grey, JWT, Ogilvy & Mather, and Young & Rubicam. In 2016, WPP generated revenue of approximately US$19 billion and had a record 205,000 employees.
Omnicom Group is the second largest advertising company after WPP Group. The New York-based company controls several businesses including BBDO Worldwide, DDB Worldwide, and TBWA Worldwide. The three agencies have an unrivalled reputation for excellent creativity. They provide services in four main areas including advertisement, public relations, CRM, and specialty services. Omnicom employs over 75,000 employees and generated US$15 billion in 2016. Its planned merger with Publics was abandoned in 2014.
The Paris based Publics Group made its way to the upper rank with strings of smart acquisitions including Leo Burnett Worldwide and Sapient Corporation. Founded in 1926, it is one of the oldest and largest marketing and communication companies in the world. It operates in over 200 cities in 105 countries. A move to merge with Omnicom Group to create the largest advertising company was abandoned in 2014. In 2016, Publics Group recorded revenue of US$9.6 billion, the third highest after WPP and Omnicom.
Although the New York-based Interpublic Group struggled through series of challenges in the 2000s, it still remains one of the big four international advertising companies. It consists of three main networks including McCann Worldgroup, FCB, and Lowe & Partners. Interpublic Group employs about 50,000 employees and recorded revenue of US$7.6 billion in 2015.
Dentsu of Japan dominates its local market more than any other advertising company. However, its popularity outside Asia was limited until recently. It operates in 145 countries and employs approximately 45,000 employees. In 2011, the company formed a partnership with Facebook to help in developing Facebook pages and ads. Facebook provides Dentsu with a premium advertising space.
Although the above five advertising and marketing groups have consistently dominated the advertising industry, they have faced new challengers for the global advertising budget with the new companies and consultancies expanding into digital marketing. Consumer groups are also rethinking their marketing spending with the companies. The emergence of Facebook and Google has been considered a threat to several marketing companies. The two have become a “digital duopoly” accounting for 60% of global digital market ads.

Everyone thinks they know who the largest marketing companies in the world are, and I’m sure you know some of the famous agencies like BBDO, Havas or Grey. But would you be surprised if I told you those agencies don’t even crack our top 10?
The landscape of global agencies has become crowded and confusing over the last 10 years. While huge agency networks and holding companies are the vanguard, there has been a convergence of consulting firms and tech giants entering the frame to compete as well as in-house agencies. All of this continues to blur the line between what is considered an agency and who is best suited to help your global marketing, advertising, and digital initiatives.
To bring some clarity to the global agency marketplace, Agency Spotter has put together the 50 largest marketing agencies according to estimated yearly revenue. This list represents the 50 biggest agencies and not the agency networks or groups like WPP, Publicis Group, Dentsu Inc, Interpublic, and Omnicom Group. If you’re looking to find your next marketing partner, keep in mind that the most helpful agency may not be the biggest or most well-known one your budget can afford you… Thankfully, Agency Spotter allows you to search for an agency by size.
