- WPP plc – One of the largest global advertising and marketing services groups.
- Omnicom Group – A major player, currently involved in a $13 billion merger with Interpublic Group (IPG) that will significantly reshape the industry landscape.
- Publicis Groupe – Another of the traditional “Big Four” global advertising holding companies.
- McCann Worldgroup – Noted for its global network and deep understanding of local cultures integrated into global campaigns.
