Warner Bros. Discovery Pushes Performance Measurement

Executive Signal Summary

Warner Bros. Discovery (WBD) used its 2026 upfront to announce two measurement initiatives focused on outcomes and speed. WBD is joining an OpenAP-led initiative to standardize a conversion API (CAPI) that will enable advertisers to connect outcomes data to their first-party data across video campaigns and will include data from other TV publishers. WBD also unveiled an Always-On Measurement & Attribution Dashboard designed to accelerate reporting so buyers can optimize campaigns in flight by linking campaign data across linear, streaming and digital to outcomes like brand lift, site engagement and sales conversions. WBD named measurement partners such as VideoAmp, EDO, LoopMe and DISQO and emphasized that agentic AI features will assist but not replace human decision-making.
