Xumo, the joint venture between Comcast and Charter, has expanded its integrations with Gracenote and IRIS.TV to bring program-level metadata and frame-level AI analysis to its free ad-supported streaming TV (FAST) inventory. The integrations cover Xumo's global footprint of 2,000 channels across more than 30 platforms. This technical deployment aims to solve historical FAST metadata gaps and enable programmatic advertisers to execute standardized, brand-safe contextual targeting at scale.
The deployment solves the 'blind spot' problem in linear FAST, where lack of standardized metadata has historically made it difficult for buyers to verify exactly what is airing. By combining Gracenote’s program-level data with IRIS.TV’s scene-level insights, Xumo is building a supply-side infrastructure that allows programmatic buyers to apply the same brand safety and contextual targeting to FAST that they use for on-demand libraries. For the broader ecosystem, this signals a shift toward context-heavy buying as a primary lever for moving traditional linear TV budgets into the FAST market. Watch for whether Xumo’s competitors, such as Pluto TV or Tubi, accelerate similar multi-layered metadata partnerships to remain biddable.
The Xumo integrations come as the FAST market experiences rapid structural growth combined with a significant measurement deficit. Per MediaPost (February 2026), FAST channel counts increased 9% in late 2025, yet only a fraction of this inventory carried the structured metadata required for programmatic biddability. Gracenote research from May 2026 confirmed that 86% of media planners would reallocate linear budgets to CTV if show-level data were available, highlighting the commercial pressure to address the signal gap that Xumo is targeting with these partnerships.
On the buy side, the involvement of IRIS.TV connects directly to the broader expansion of Viant Technology, which acquired IRIS.TV in November 2024. Per StreamTV Insider (May 2026), Viant reported that IRIS_ID availability in the bidstream grew from under 10% in 2024 to 50% by mid-2026. This growth is being further leveraged following Viant’s $40 million acquisition of TVision Insights in May 2026, which added person-level attention measurement to its stack. By integrating these systems, Viant is attempting to create a 'trifecta' of identity, context, and attention for advertisers seeking objective measurement outside walled gardens.
Recent momentum for Xumo itself is tied to its role as a hardware-integrated platform. Per Xumo (February 2026), Xumo-branded devices saw 78% year-over-year viewing hour growth in 2025. This hardware footprint creates a controlled environment where the company can deploy advanced ad formats, such as the pause ads launched in November 2025 that reportedly drove a 276% lift in QR code scans. The addition of verified contextual signals from Gracenote and IRIS.TV represents the next phase of this monetization strategy, moving beyond engagement metrics to provide the transparency essential for institutional brand spend.
