Consolidation as Answer?
In December 2024, Omnicom acquired Interpublic to leapfrog Publicis and WPP to become the largest agency with combined revenues of over $25 billion.
Here is some of the commentary that followed the announcement.
RTE: “Tech giants such as Alphabet-owned Google and Amazon.com have in recent years attracted marketing dollars away from traditional agencies by offering both advertising tools and marketplaces to buy and sell them. Soaring use of AI tools that allow businesses to create ads cheaper and faster has also squeezed traditional agencies, forcing them to scramble to develop similar in-house tools to retain clients. With more tech-driven solutions coming into the market, MoffettNathanson analyst Michael Nathanson said he was concerned the underlying value proposition of an ad agency’s offering would remain pressured.”
PR Week: “Syracuse University PR professor and former national chair of the Public Relations Society of America, Tony D’Angelo, said…“Omnicom and IPG are betting that their combined scale will give them bigger scale and more leverage with tech providers, and with their media buying and planning.” He added that the acquisition is evidence of how digital and AI technologies are changing the PR landscape. “The holding companies and their agencies will tout this as beneficial to clients, and it may help them deliver additional benefits,” he added. “However, clients may well wonder if they’ll get the attention they need from the larger entity.””
AdWeek: “The acquisition reflects the growing value of data and digitally oriented agencies, the opportunity presented by new technologies like generative artificial intelligence…A core element of the Omnicom takeover is the possibility it presents for the resulting company to serve all of its clients but with fewer personnel, according to Quantum Media principal and New York University professor Erica Gruene. “It’s like the old maxim: The only thing an ad agency owns gets in the elevator and goes down every night,” Gruene said. “And nowadays, you don’t need as many people in the elevator.””
FT: “Advertising rivals question whether the deal has been struck from a position of strength with Sir Martin Sorrell, founder and executive chair of S4 Capital, calling it “a circling of wagons; two people huddling in the cold”. [He said], “This is a reflection of the pressure on agency fees, people and margins together with the spectre of the impact of artificial intelligence and increased programmatic media planning and buying.”… Advertising executives saw the irony of announcing the deal as a new report from WPP’s GroupM came out showing that the industry had rocketed to over $1tn in revenues — but also revealing that more than half of the value was now in the five large tech groups, who accounted for almost all of the growth. The report underlined the need for consolidation in the traditional agency holding company model. Executives agree that the future will be about investing in AI and other technology that allows advertising to be done faster, cheaper and more effectively for clients. One area where scale will potentially make a difference is data and AI investment, with the combined group having increased firepower to invest resources in this area, according to analysts.”
WSJ: “If the Omnicom-IPG deal goes through, the combined company will supplant WPP’s GroupM as the largest global media buyer and gain new leverage with ad sellers in the process, according to Comvergence, a market research firm. Any increased buying power the merger could offer would be welcome, as would the companies’ combined technology resources, including emerging artificial intelligence capabilities, some marketers said. “Scale does matter, global scale does matter, efficiency does matter, and innovation does matter,” said Doug Sweeny, the CMO of wearable tech company Oura Health…“Building out their AI, which can impact business in a way that we’re not entirely clear about, as a larger entity together will make them more formidable to pressures on their moat.””
What’s abundantly clear is that traditional agencies face an existential inflection point—consolidation merely addresses symptoms while ignoring the underlying disease. The Omnicom-IPG merger represents a defensive manoeuvre in an industry fundamentally threatened by both technological disruption and structural inefficiency. The path forward demands more than scale; it requires dismantling the acquisition-centric paradigm that has dominated marketing for two decades and replacing it with a retention-first model that eliminates the systemic waste of repeatedly paying to reach existing customers. The agency of the future will emerge not from incremental adaptation but from radical reinvention—one that transforms marketing from a cost centre driven by ephemeral impressions into a profit engine powered by sustainable customer relationships.
