Legacy Agencies Disappear Amid Omnicom Consolidation

The Chicago advertising landscape is undergoing a dramatic shift following Omnicom’s multibillion-dollar acquisition of IPG. This merger has effectively eliminated some of the city’s most storied agency brands, including MullenLowe, FCB, and DDB—names that once held significant influence in the Windy City’s creative circles. For decades, these agencies were synonymous with the identity of Chicago advertising, but now they’ve been folded into Omnicom’s broader organizational framework.

“It’s almost like a memorial service,” says Janet Barker-Evans, CCO at AbelsonTaylor Group. She describes a wave of emotion and reflection among industry peers who are mourning the loss of agencies they once called home. The merger has not only changed names but also raised questions about what is truly lost when iconic brands vanish.

Nostalgia vs. Progress in Healthcare Advertising

Neil Matheson, CEO of Citrus Health, acknowledges the deep roots of healthcare advertising and the evolution of key players like Medicus and Harrison & Star from earlier firms. Yet, he emphasizes the importance of forward momentum. “We can’t look back. We can only look forward,” he states, signaling a broader industry sentiment that adaptation is essential in an era of relentless transformation.

The concern among many, however, is that consolidation leads to homogeneity, stripping away the unique culture and identity that once defined individual agencies. Barker-Evans notes that clients and employees choose agencies not just for services, but for their distinct voices and values. The homogenization of agency culture, she warns, could alienate both.

Client Loyalty and Brand Identity at Risk

One of the significant risks of this large-scale merger is client retention. Barker-Evans explains that if clients perceive they are being transferred to a generic entity focused more on margins than on personalized service, they may begin seeking alternatives. This is especially relevant in the pharma space where trust and tailored strategies are paramount.

Molly Lane, EVP of brand strategy at Merge, believes the heart of any agency lies in its talent and entrepreneurial spirit. She asserts that while names may change, the core skills and passion of the team remain intact. Still, she acknowledges the urgency for the new Omnicom agencies to define their culture quickly to avoid client attrition.

Independent Agencies Eye Opportunity

As Omnicom absorbs legacy brands, independent medical marketing agencies in Chicago see a potential opening. Since the merger was announced in December 2024, several indie firms have expressed optimism about attracting disillusioned clients and talent looking for more meaningful work environments.

While no agency has publicly confirmed a client win directly linked to the merger, some professionals have already exited Omnicom’s orbit for roles at independent firms. Lane notes this trend began nearly a decade ago, as independent agencies started to gain traction and prove that success doesn’t always require affiliation with a major holding company.

The AI Factor and Remote Work Reality

Artificial intelligence and digital transformation have also played a significant role in reshaping agency dynamics. Matheson points out that AI has accelerated the push for operational efficiency, prompting agencies to streamline processes and cut costs, often at the expense of legacy agency identities.

Moreover, the post-pandemic shift to remote work has diminished the need for physical offices in Chicago, weakening the traditional bonds that once fostered strong team culture. “Clients are commenting that people have become very transactional,” Matheson says, suggesting that the human element of agency-client relationships is at risk.

Declining Opportunities for Junior Talent

The current state of Chicago advertising also paints a challenging picture for junior talent. Entry-level hiring has slowed, and the perception that AI is taking over creative jobs has discouraged many recent graduates from entering the field. For young professionals hoping to build careers in the Midwest’s largest city, the outlook is increasingly uncertain.

Despite these challenges, both Lane and Matheson urge new entrants to focus on skill development, adaptability, and personal branding. Rather than anchoring their aspirations to a geographic location or a legacy name, they recommend embracing the evolving nature of the industry and seizing opportunities where they arise.

The Risk of Monoculture in Advertising

The broader concern among many industry veterans is that as consolidation continues, healthy competition—which drives innovation and excellence—may be replaced by a monoculture. “You play for team, you play for country — but then there’s no longer a team. It’s just a country,” Barker-Evans reflects, capturing the emotional toll of losing agency identities that once fueled professional pride and creativity.

As the dust settles from the Omnicom merger, Chicago’s ad scene stands at a crossroads. While the city’s legacy may be fading, new opportunities are emerging for those willing to adapt, innovate, and redefine what it means to be part of this evolving industry.
