Before Agentic TV: The Foundations of a Marketer-First Buy

FOX Advertising announced last week the launch of what is the industry's first end-to-end agentic advertising platform, and Simulmedia is honored to be their TV transactions partner.

For the marketer, an agentic advertising platform is only as good as what it transacts against and on whose behalf it acts. At Simulmedia, a media buy exists for only one purpose: to deliver the marketer's desired outcome. A media buying agent can only serve the marketer's goals if the buying layer beneath it is already built around the marketer rather than the media or measurement, and while CTV has that layer natively, linear television has never had it, which is precisely the technology we have built at Simulmedia.

This post describes how a linear buy actually comes together on Simulmedia's platform, and the foundational pieces that make such agentic transactions possible.

The Buy Starts with the Marketer's Audience

Marketers do not want adults 25 to 54; they want their own customers and the prospects most likely to convert. Simulmedia's platform ingests whatever audience the marketer defines, whether that is first-party data, retail and commerce segments, clean room outputs, or third-party providers, and treats that as the target audience. The marketer sets who matters, and the platform does not constrain them to a predefined taxonomy.

Fragmented Inventory, Transactable as a Single Pool

TV inventory is split across national cable, broadcast, syndication, local television, and streaming, and every seller carries its own pricing, rate card, order workflow, and measurement, which is a fragmentation that works squarely against the marketer. Simulmedia's platform normalizes all of it into a single supply model and a common ontology, so that a buyer, or a buyer's agent, can evaluate more than 1,000 local broadcast stations, dozens of cable operators, hundreds of syndicated programs, and hundreds of television networks on identical terms, in service of one campaign and one outcome. The alternative is the status quo: a dozen disconnected buys that may still miss the target, or a buy constrained to a handful of sellers because executing across all of them is not operationally feasible.

Delivery Is Forecast Before Anything Is Purchased

Once audiences and inventory share a common language, delivery becomes something the platform can predict. Simulmedia's platform forecasts reach, frequency, and outcome delivery against the marketer's actual audience before anything is purchased. The marketer knows whether the plan will hit their goal before committing to it, and an agent needs that same visibility before it can responsibly go out and buy one.

Optimization Against the Marketer's Outcome, Not Third-Party Currencies

Linear is bought and sold on Nielsen demographic CPMs, but the marketer wants short and long term business results. Simulmedia's optimization engine closes that gap, identifying the inventory that delivers the most of the right people, measured against the marketer's real target, at the lowest cost, so that the outcome is what the buy is actually optimized to achieve.

Execution Happens Without Bottlenecks

This is the least visible layer and the one that makes the rest possible, because even a precise plan cannot deliver anything if it cannot be executed at scale. Once a plan is approved, the Simulmedia platform breaks it into hundreds of packages, one for each media seller, and sends each seller its own optimized plan with the specific spot selections already chosen. The network is not asked to optimize anything on our behalf; it receives a finished plan, and where it does not have the inventory to fulfill a given spot, the platform recommends alternatives in its place or evaluates alternatives from the network.

Orchestration Runs Across the Entire TV Ecosystem at Once

The larger networks transact through agents and APIs, while other sellers prefer to use the Simulmedia publisher portal to receive each order and insert it directly into their systems. Across every one of these connections, orders, revisions, make-goods, and delivery tracking run automatically, and the plan reaches air as it was designed in a matter of minutes.

Orchestration is also where LLM-based agents earn their place, not as an external chatbot, but as the technology layer that holds everything together. Hundreds of flows, pre-orders, confirmations, and formats come back from these sellers in real time, and every one has to be checked against the plan for a buy to actually clear. Historically this meant writing and maintaining custom scripts for each seller's quirks, which broke the moment a format changed. Now agents read the raw material directly, whether it arrives as an API response, an uploaded file, or an email, and use retrieval and reasoning to normalize each one into the platform's common ontology and take the appropriate action. The result is that the messy, human edges of the TV ecosystem get absorbed into the same programmable layer as everything else, rather than sitting outside it as manual exceptions.

Taken together, these layers make the buy side of linear television programmable and agentic, with the marketer's outcome sitting at the center of it, so that a buyer, or an agent acting on a buyer's behalf, can define an audience, forecast a plan, optimize against a real goal, place the orders, monitor delivery, and reallocate spend across linear TV in the same way they already do in digital.

Making linear television transactable on the marketer's terms has been Simulmedia's mission from day one. It was a genuine pleasure to find a partner in the FOX team who set out to solve the same problem, and we are glad to be part of what they have built.
