Cannes Lions opens today. In the 72 hours before it, six companies announced agentic advertising products. Two of them are media companies: Fox Corporation and Warner Bros. Discovery. People Inc is not among them.
This matters architecturally. D/Cipher is an intelligence layer — contextual understanding powered by OpenAI. Fox AdStudio and WBD's AWS stack are infrastructure layers — agent-to-agent communication, automated workflows, composable order management. The difference: intelligence without infrastructure can be bypassed. Infrastructure with intelligence becomes the platform.
What Fox Built
On June 17, Fox announced what it calls the TV industry's first end-to-end agentic advertising platform. FOX AdStudio launched in April as a unified data platform. Now it has agents.
The architecture has three functional domains:
| Domain | Partners Testing | What the Agents Do |
|---|---|---|
| Audience Planning | WPP, Horizon Media | Audience discovery, forecasting, media recommendations |
| Digital Transactions | Comcast Universal Ads | AI-assisted briefing and transaction workflows |
| Linear Transactions | Simulmedia | Automated linear transaction capabilities |
Phase 1 is live now: buy-side agents connect to Fox's sell-side agents via authenticated tokens. They test audience targeting, generate forecasts, execute media buys. Phase 2 (H2 2026) widens the partner set and adds agent-assisted workflows across linear and digital programmatic guarantees.
The critical detail: Fox built a sell-side agent that external agents can talk to. This is infrastructure. It doesn't matter what intelligence the buy-side uses — Fox is the endpoint.
What WBD Built
Warner Bros. Discovery rebuilt its entire ad-tech stack on AWS. Not a feature. A re-architecture.
Led by Dr. Nage Sethu, SVP of Technology for Converged Advertising. The system unifies linear and digital advertising workflows that were previously siloed across business units. Agentic automation handles direct response, commercial workflows, audience forecasting, and measurement.
Two things stand out. First: WBD chose AWS over Google. This is a deliberate infrastructure bet — cloud-native agentic services, not sitting atop an existing ad server. Second: the timeline is aggressive. Composable order management by Q4 means agents can negotiate, price, and execute campaigns without human workflow.
What People Inc Has
D/Cipher sits atop Google Ad Manager. It uses OpenAI for contextual understanding — mapping audience intent signals across content. Orders that include D/Cipher provide over half of direct digital revenue, and those orders are 50% larger than orders without it.
That's a real business. But it's not infrastructure. The architecture looks like this:
When a buy-side agent wants to transact with Fox, it connects to Fox's sell-side agent via authenticated token. When it wants to transact with WBD, it talks to AWS Bedrock AgentCore. When it wants to transact with People Inc, it talks to... Google Ad Manager. The same Google Ad Manager that everyone else uses.
D/Cipher makes People Inc's inventory smarter. It doesn't make People Inc's inventory reachable by agents. Those are different engineering problems.
The Infrastructure Hierarchy
The agentic advertising world forming at Cannes has a clear hierarchy:
D/Cipher lives at the Intelligence tier. It makes People Inc's content more valuable to agents — better contextual matching, higher relevance scores. But it doesn't give People Inc a sell-side agent endpoint. It doesn't give buy-side agents an authenticated way to discover, negotiate, and execute directly. That infrastructure belongs to Google.
Fox and WBD moved to Platform. People Inc stayed at Intelligence. The consequence: when NVIDIA partners demonstrate 2x speedups on Blackwell GPUs for real-time bidding, those speedups flow to platforms that own their transaction layer. When OpenAI's CRO takes the main stage today to discuss agentic commerce principles, the publishers she's addressing are the ones who built endpoints for agents to reach.
The Peer Comparison
Fox is a media company. Not an ad-tech vendor. Not a cloud provider. A media company that airs NFL games, produces news, runs streaming services. It looked at the agentic transition and decided to build infrastructure. It hired WPP and Horizon to test. It launched before Cannes.
WBD is a media company. It runs HBO, CNN, Discovery+. It chose AWS over Google. It committed to a ground-up rebuild. Composable order management by Q4.
People Inc is a media company. It runs 40+ brands, publishes recipes and celebrity coverage, operates Food & Wine Classic. It has D/Cipher — arguably the best contextual intelligence in publishing. It also has no sell-side agent. No AAMP registration. No Cannes presence. No infrastructure partner announcement.
This isn't about capability. It's about architectural commitment. Fox and WBD chose to own the transaction layer. People Inc chose to rent it from Google.
What This Means for the Engineering Org
If you're leading engineering at People Inc, the question isn't whether D/Cipher works. It works. The question is whether an intelligence layer without an infrastructure layer creates vendor lock-in to Google's transaction infrastructure at exactly the moment that infrastructure is being disrupted.
The minimum viable agentic stack for a publisher requires three things D/Cipher doesn't provide:
- A sell-side agent endpoint — authenticated, discoverable, capable of receiving queries from buy-side agents without going through Google Ad Manager
- Protocol compliance — registration with AAMP, AdCP, or equivalent so agents can find you
- Composable transaction capability — the ability to negotiate, price, and confirm buys programmatically at the agent layer, not just serve impressions
Fox built all three. WBD is building all three (Q3-Q4 timeline). PubMatic's AgenticOS offers all three as a service (running in 5 countries, 2K+ publishers).
People Inc has zero of three.
"Agent-to-agent workflows will be underpinned by a security and governance-first protocol to ensure the system powers real, trusted applications at scale."
— Fox Corporation, June 17, 2026
This is what infrastructure sounds like. Not smarter targeting. Not better contextual matching. A protocol for agents to talk to each other, with security and governance baked in. When Fox says this, they're describing something D/Cipher was never designed to do — and something Google Ad Manager was never designed to expose.
Cannes Day 1. The builders have arrived. The question for People Inc's technology organization is whether D/Cipher's intelligence advantage — real, valuable, revenue-generating — can survive as a feature atop someone else's infrastructure. Or whether it needs its own foundation.
