Omnicom this morning announced its post-Interpublic org structure and leadership team, which notably omits a number of Interpublic legacy media brands, including IPG Mediabrands, as well as its Magna media economics, intelligence and centralized media negotiations unit.

In their place, Omnicom unveiled a new Omnicom Media Group org structure consisting of six flagship media agency services brands -- OMC, Initiative, UM, PHD, Hearts & Science and Mediahub.

Those agencies, as well as Acxiom -- the Big Data consumer division that Interpublic paid $2.3 billion for in 2018 -- report to Omnicom Media CEO Florian Adamski, former CEO of Omnicom Media Group.

The new Omnicom Media also appears to have sunset the work "Group," suggesting the OMG acronym may have also gone with it, though a pulldown menu on its new website still has a "Life at OMG" tab, which nonetheless describes "Omnicom Media."

Most of the new Omnicom Media executive team is comprised of former OMG executives, with the exception of Justin Wroe, former IPG Mediabrands U.S. CEO, who becomes Chief Commercial Officer; and Daniel Fox, former Chief Investment Officer at IPG Mediabrands, and Jonathan Rigby, former Chief Strategy Officer at IPG Mediabrands, who assume those same roles at Omnicom Media.

Notably missing from the new Omnicom Media org structure is former IPG Mediabrands Global CEO Eileen Kiernan, who helped transform the organization prior to its merger with Omnicom.

Stacy DeRiso and Susan Kingston-Brown remain heads of the former IPG Mediabrands' Initiative and UM units in the new org structure.

Ralph Pardo, former CEO of OMG North America, has been named interim U.S. CEO of Hearts & Science.

The new Omnicom Media site also promotes some new branding, including the tagline: "We Design Ecosystems For Growth," which is a telling position for a big agency holding company media services unit to take in a post-media-buying world.

Among the capabilities listed in its pitch slides is that it represents $73.5 billion in "buying power," which would give it about a 7.4% share of global ad spending according to Magna's roughly $1 trillion global ad forecast for 2025.

On that note, it looked uncertain that there will be a continuing legacy for Interpublic's pioneering role as an ad industry forecaster, which was originally conceived the practice in 1948 and sparked many notable competitors among the major agency holding companies, with the exception of Omnicom, which never officially released ad industry spending totals.

At presstime, an Omnicom spokesperson had not answered a MediaPost query about whether Omnicom would continue publishing forecasts.

Pubicis' Zenith Media previously sunset its public forecasts, and while Dentsu typically releases an annual update early every year, that leaves WPP Media's Kate Scott-Dawkins as the last official agency holding company forecaster to regularly publish them publicly.

Interestingly, Scott-Dawkins is scheduled to present her year-end update and 2026 outlook alongside former Magna executive Luke Stillman, who is now managing director of Madison and Wall, and independent consulting and newsletter publishing company founded by former Interpublic and GroupM (now WPP Media) exec Brian Wieser at UBS annual Global Media and Communications Conference Dec. 8 in New York City, which historically was where the big agency holding company forecasting execs first tip their outlooks for the upcoming year.

As for its big upcoming public events, Omnicom's announcement this morning plugs its participation in CES 2026 in Las Vegas in January; it's year-end earnings report in February 2026, and an annual "Investor Day," which has not yet disclosed a date.
