The transition comes as Turnbull prepares to depart McCann, a cornerstone of the global advertising landscape. His tenure at McCann, while relatively brief following his appointment to the top position in December 2025, was defined by a period of historic transformation within the industry. During this time, Turnbull was a central figure in managing McCann’s integration into the Omnicom Group following its landmark acquisition of the Interpublic Group (IPG). This merger, one of the largest and most consequential in the history of the advertising business, necessitated a massive restructuring of agency assets. Under the new Omnicom hierarchy, McCann was positioned as one of three primary global creative networks, alongside BBDO and TBWA. Navigating this transition required a delicate balance of maintaining McCann’s unique culture and legacy while aligning its operations with the broader strategic objectives of the newly expanded Omnicom holding company.
Turnbull’s move to WPP is seen by many industry observers as a major coup for the London-based holding company. Known for his ability to breathe new life into struggling or stagnant agency offices, Turnbull first rose to international prominence during his time at FCB Global. Before the agency was eventually shuttered, Turnbull was widely credited with the successful turnaround of FCB’s Canadian operations. When he took the helm in Canada, the outpost was facing significant challenges in a competitive market. Through a combination of strategic restructuring, a renewed focus on creative excellence, and aggressive business development, Turnbull transformed the office into a powerhouse within the FCB network. His leadership was instrumental in securing high-profile accounts with major brands such as Home Depot, Air Canada, and BMW Canada, demonstrating a knack for winning and retaining blue-chip clients in diverse sectors.
This success in the Canadian market served as a springboard for Turnbull’s ascent within the global advertising hierarchy. By 2022, his track record of operational success and creative growth led to his appointment as the global CEO of FCB. In that role, he was tasked with overseeing the agency’s worldwide footprint, ensuring that the momentum he built in North America could be replicated across other regions. His reputation as a "turnaround man" made him an attractive candidate for leadership roles at a time when traditional advertising agencies were facing increasing pressure from consultancy firms, in-house brand teams, and the rapid rise of digital media platforms.
The creation of the Global CEO of WPP Creative role reflects a broader trend within the advertising industry toward holding company consolidation. For years, groups like WPP, Omnicom, and Publicis operated as loose federations of independent agency brands, each with its own leadership, culture, and bottom line. However, the modern marketplace has increasingly demanded more integrated solutions, leading holding companies to merge formerly distinct agencies and create centralized leadership tiers. WPP has been at the forefront of this shift, recently overseeing the high-profile merger of VMLY&R and Wunderman Thompson to create VML, as well as the integration of AKQA and Grey. By bringing in Turnbull to lead "WPP Creative," the holding company appears to be signaling a desire for a more cohesive creative strategy that transcends individual agency silos.
