Grey

A century-old global creative agency network, now integrated into Ogilvy within WPP, serving major multinational advertisers across consumer, healthcare, and financial categories.

Grey is one of the world's most storied advertising agency networks, founded in 1917 and long known for its creative work across consumer goods, healthcare, financial services, and technology sectors. The agency built its reputation on iconic campaigns for clients such as Procter & Gamble, Volvo, Gillette, and GlaxoSmithKline, operating across dozens of markets globally with deep capabilities in brand strategy, creative development, media planning, digital marketing, and integrated communications. As of May 2025, Grey has been folded into Ogilvy as part of WPP's ongoing strategic reorganisation of its agency portfolio. This realignment brings Grey's creative talent and client relationships under the Ogilvy umbrella, consolidating two of WPP's most prominent creative networks. Prior to this, Grey had been grouped with AKQA under the AKQA Group banner before that arrangement was unwound in the same WPP restructuring. Grey's significance in the advertising industry stems from over a century of creative output, a global footprint spanning major markets across North America, Europe, Asia-Pacific, Latin America, and the Middle East, and a client roster that has historically included some of the world's largest advertisers. Now operating within Ogilvy, Grey's capabilities contribute to one of the largest integrated creative and communications offerings in the WPP network.
