WPP & GroupM

MediaCom was founded in 1986 in Europe as a subsidiary of Grey Advertising, and soon expanded throughout the world. In 2006, after acquisition of Grey by WPP, MediaCom became a key part of GroupM, WPP’s global media operations arm.

Together with our GroupM partners, we are responsible for $104.5 billion*
in media buying, equalling to a 33% market share (source: Recma) – which enables us to offer our clients unparalleled negotiation power.


GroupM is the leading global media investment management company for WPP’s media agencies including Mindshare, MediaCom, Wavemaker, Essence and m/SIX, and the outcomes-driven programmatic audience company, Xaxis. Responsible for more than US $108B in annual media investment by some of the world’s largest advertisers, GroupM agencies deliver an advantage to clients with unrivaled insights into media marketplaces and consumer audiences. GroupM enables its agencies and clients with trading expertise, data, technology and an array of specialty services including addressable TV, content and sports. GroupM works closely with WPP’s data investment management group, Kantar, and together they account for almost 50% of WPP’s group revenues of more than US $19B. GroupM delivers unrivaled marketplace advantage to its clients, stakeholders and people.
