Next in Media: "How Yahoo DSP Is Winning the Identity and CTV Wars"

Host: Mike Shields
Guest: Adam Ruman, General Manager, Yahoo DSP
Date: March 17, 2026

Episode Overview

In this episode, Mike Shields sits down with Adam Ruman, GM of Yahoo DSP, to unpack how Yahoo has navigated massive shifts in media, marketing, and advertising, especially in Connected TV (CTV) and identity resolution. They discuss the ongoing "DSP wars," Yahoo's unique strengths, its response to the rise of agentic advertising, and how data-driven strategies are setting new industry table stakes. The conversation is candid, tech-forward, and full of real-world examples, memorable moments, and expert takes on the rapidly evolving landscape.

Key Discussion Points & Insights

1. Yahoo’s Ad Tech Evolution and Strategy

• Shift to Demand-Side Platform (DSP) Focus
  • Yahoo moved from a multi-pronged ad tech model (including SSPs and native ad networks) to a purely DSP-centric approach in recent years.
    • “Now it is solely demand side, platform centric approach.” (02:55 – Adam)
• Strategic Advantage: Data Footprint
  • Yahoo leverages its vast consumer and owned & operated data to deliver enhanced performance for advertisers.
    • “The real reason ... that it lends itself well to a programmatic ad stack strategy would be the data footprint and the consumer footprint.” (04:51 – Adam)

2. CTV Identity: Accidental Leadership

• Building an Identity Graph Pre-Cookies Deprecation
  • Yahoo anticipated a cookieless future and built a people-based identity graph, which later became essential for CTV—where authentication is typically email-based.
    • “When we built that identity graph and started building it, CTV was nascent at best … what it's turned into is this juggernaut for CTV buying.” (06:12 – Adam)
    • Over 90% of Yahoo DSP’s CTV buys now leverage this deterministic identity.
• Household vs. Individual Targeting
  • There’s ongoing debate about targeting on a household vs. individual basis in CTV. Yahoo supports both but argues individual targeting is increasingly important as user behavior changes.
    • “We would not have come up with household-based targeting 30, 50 years ago if we had the ability to do individual ... that is a new development that's well supported by having individual based identity graphs with people resolution.” (08:34 and 09:34 – Adam)
• CTV as a Performance Vehicle
  • The convergence of addressable inventory and identity enables both branding and performance-driven campaigns in CTV.
    • “Targeting individuals lead to good performance … this medium allows you to go full funnel and so you don't have to pick.” (10:36 – Adam)

3. Rise of Agentic Advertising and Protocols

• Yahoo’s Agentic Strategy
  • Yahoo introduced an adaptable strategy for agentic workflows:
    • “Yours”: Clients can create and run their own agents on Yahoo’s ecosystem.
    • “Mine”: Third parties can port their agents to Yahoo and work collaboratively.
    • “Ours”: Yahoo’s native agents are built directly into its DSP.
  • “It's that flexibility ... that we're not picking one way to use agent.” (14:20 – Adam)
• Impact on Workflow and Productivity
  • The agentic revolution aims to automate repetitive tasks, free up human capacity, and potentially reshape job roles.
    • “It’s changing the output of a power worker today ... now the bandwidth just changes completely.” (19:27 – Adam)
  • Comparison to programmatic: While programmatic solved for scale in buying, agents focus on streamlining the accompanying workflow and analytics.
    • “Programmatic was never really sold as this time-saving mechanism ... Agentic does come in at a time to address that stuff.” (18:28 – Adam)

4. Fraud, Hallucinations, and Table Stakes of AI

• Ensuring Trustworthiness in Agentic Systems
  • Quality documentation and “AI librarian” roles are now critical to prevent errors, hallucinations, or fraud in automated advertising flows.
    • “The table stakes are huge. The quality of content has to be really good and accurate, written with good context.” (22:09 – Adam)
    • “We've evolved ... it’s really an AI librarian type function becoming really critical.” (23:01 – Adam)
• Human Oversight Remains Key
  • Structural safeguards, SSO authentication, and human intervention are required for error-sensitive, enterprise-level campaigns.
    • “You have to be very, very careful ... so that nothing comes off the guardrails.” (24:15 – Adam)

5. CTV Supply & The Open Web Redefined

• Growth in Addressable Inventory
  • Despite some views about the “shrinking web,” Yahoo sees increasing open, addressable, and biddable inventory, especially in CTV and audio.
    • “Our inventory footprint of what we consider the Open Web is ... going up, not down … so that liquidity of inventory is not a problem.” (25:07 and 26:04 – Adam)
• Programmatic Isn't Just Open Market
  • Private marketplaces (PMPs), direct deals, and open market all coexist in CTV; both present opportunities.
    • “For me, they're both considered opportunities.” (26:24 – Adam)

6. Protocols and Interoperability: The Industry Debate

• MCP vs. ADCP and The Future of Protocols
  • Yahoo is live with Model Context Protocol (MCP) but is also invested in other industry efforts like ADCP.
    • “We've got the capability to interact with multiple (protocols) ... what we have put out in market that's live today is predominantly on MCP.” (28:29 – Adam)
  • Protocol changes don’t need to be binary or contentious—interoperability is key.

7. Pace of Change & Advice for Brands and Agencies

• Rapid Acceleration of Agentic Tech
  • This wave of automation is happening much faster than previous AI-driven transformations in ad tech.
    • “This one's going much, much, much quicker ... I think it's going to be quicker than most people realize.” (30:29 and 32:16 – Adam)
• Advice for the Hesitant
  • The technical barrier to entry is now low; the real challenge is organizational adaptation.
    • “Someone could stand up an MCP is ... an overnight job ... The part is structuring an organization to take advantage of it.” (32:58 – Adam)
    • “Come on in if you haven't by now ... it's pretty convincing once you start operating in it.” (33:29 – Adam)

Notable Quotes & Memorable Moments

• On Identity in CTV:
  “Your accuracy goes through the roof. And when you have higher accuracy you can bid with more conviction and you can deliver a better outcome.” (06:42 – Adam)

• On Individual vs Household Targeting:
  “You definitely don't want to target me with the stuff that you intended for my teenage son. That's probably not my consumer differentiant.” (09:34 – Adam)

• On Agentic Advertising:
  “We don't think having agentic is a strategy. It's how you operate it is a strategy.” (12:51 – Adam)

• On the Human Side of AI:
  “I got into a fight with one of our internal agents literally this week.” (22:01 – Adam)

• On Table Stakes in Modern Ad Tech:
  “The quality of content has to be really, really good and accurate, written with good context. We've evolved the thinking of what used to be more of a tech writer type functionality. It's really like an AI librarian type function becoming really critical.” (23:01 – Adam)

• On Industry Change:
  “It’s changing the output of a power worker today, that’s for sure ... what do you do with that bandwidth?” (19:27 – Adam)
