Magnite and LG Ad Solutions have introduced agentic AI media buying for LG smart TV home screen inventory. The Northern California Toyota Dealers Association became the first to utilize this system for a campaign featuring NFL quarterback Brock Purdy.
Why it matters
This shift toward agentic workflows aims to increase the speed and efficiency of ad transactions by automating planning and execution steps. It allows brands to secure high-visibility home screen placements before viewers initiate streaming content.
The system utilizes agentic infrastructure built on existing programmatic platforms to execute campaigns, with human oversight required for final approval. The inaugural deployment targeted NFL viewers for an automotive promotion.
The players
Magnite
A sell-side advertising platform providing programmatic infrastructure for digital content owners.
LG Ad Solutions
A division of LG Electronics that leverages proprietary smart TV data for advertising across its device ecosystem.
Northern California Toyota Dealers Association
A regional group of automotive dealerships coordinating marketing and sales initiatives.
H/L
A creative and media agency specializing in automotive advertising campaigns.
The details
The system relies on the Model Context Protocol, which allows buyer agents to communicate directly with seller agents within Magnite's ClearLine platform. H/L agency initiated the process by inputting audience criteria, such as NFL viewership and auto purchase intent, which the agentic system then used to draft the media plan. Human personnel reviewed and approved the plan before the ads were deployed to the LG home screen.

Advertisers should monitor whether this agentic approach reduces operational overhead enough to justify the necessary technical integrations. Assess your current programmatic partners for compatibility with agent-based protocols before committing to new infrastructure.
The takeaway
Agentic media buying represents a shift toward automated, high-speed transaction workflows in programmatic advertising. Operators should track the efficiency gains reported by early adopters to determine when these systems move from pilot programs to standard industry practice.
