This week on Next in Media, I sat down with Matt Spiegel, EVP of Marketing Solutions Growth Strategies at TransUnion, to unpack one of the most pressing questions in advertising right now: what's actually changed since cookies started disappearing and privacy laws started piling up? And just as importantly, what hasn't changed? Matt brings a refreshingly practical perspective to the conversation, explaining how disconnected data infrastructure remains the biggest obstacle for most brands, even as everyone races to adopt AI-powered marketing. He breaks down why walled gardens still have an inherent advantage, how signal loss is forcing marketers to rethink their strategies, and why the industry's obsession with the "easy button" might be holding progress back.

We also tackled some uncomfortable truths about where the industry is headed. Matt shared his thoughts on agentic advertising and whether bots will really replace media planners, the noisy MarTech landscape that's overwhelming CMOs, and why he believes the next economic downturn could trigger massive layoffs in marketing and advertising. Throughout our conversation, Matt emphasized that while the tools and technology are evolving rapidly, the fundamentals of good marketing haven't changed. It's about understanding your customers, connecting your data, and applying that intelligence at scale. This is a conversation for anyone trying to make sense of the chaos in modern marketing, wondering how to navigate identity resolution in a post-cookie world, or just trying to figure out which AI tools are actually worth the hype.

Key Highlights

🔌 The Infrastructure Problem: Most brands lack connected data ecosystems. Their CRM, transaction records, and marketing databases exist in silos, making it nearly impossible to achieve the precision marketing everyone's chasing.

🏰 Walled Gardens Still Win: Large platforms have a scaled, dimensional view of consumers that few brands can match. The "easy button" appeal is real, but it comes at the cost of transparency and cross-platform measurement.

🤖 AI Won't Replace Humans (Yet): Agentic advertising is coming and will automate significant portions of media buying, but Matt believes we'll keep humans in the loop. The idea that bots will fully control everything is overdone, at least for now.

📊 Data Hygiene Still Matters: Simple things like ensuring "Matt" and "Matthew" are recognized as the same person remain real obstacles. Many organizations are still working through basic data cleaning before they can even think about advanced AI applications.

📉 Layoffs Are Coming: Matt predicts the next economic downturn will trigger massive job losses in marketing and advertising as automation takes over manual tasks. New roles will emerge, but there will be a painful transition period.

📈 The Measurement Mess: Between attribution debates, walled garden metrics, and inconsistent cross-platform views, CMOs are struggling to prove ROI. The complexity isn't just technical, it's political inside organizations.

🎯 Outcomes Over Tactics: Despite all the noise around cookies, signal loss, and AI, the fundamentals haven't changed. Great marketing still comes down to understanding consumers holistically and applying that intelligence strategically.

⚡ It's a Noisy Time: Marketers are juggling CIOs demanding new tech, CFOs questioning results, platforms promising exclusive deals, and measurement reports that don't add up. It's chaotic, but navigable with the right analytical mindset.
