TV Embraces an Outcomes-Driven Era
VideoWeek published an interview (April 29, 2026) with Rob McLaughlin, Founder & CEO of Audiences, filmed at New Video Frontiers 2026 in London. McLaughlin says the TV advertising market is entering an "outcomes era," driven by rapidly expanding addressability in TV which improves the ability to target and measure advertising outcomes. The interview covers drivers of TV addressability growth and practical approaches to outcome measurement in TV and connected/streaming environments. The piece was written by Tim Cross-Kovoor, Assistant Editor at VideoWeek.
CTV Measurement: From Impressions to Outcomes (Marketecture Live)
Jenny Wall of VideoAmp and host Ari Paparo discuss the evolution of connected TV measurement beyond traditional impressions and demos. The conversation covers outcomes-based attribution, advanced audiences, and the use of clean rooms, emphasizing the need for multiple currencies across linear, streaming, and walled gardens. They provide practical examples supporting audience-first buying, call for independent measurement, and caution against sticking to legacy metrics. Takeaways include that TV can deliver measurable business outcomes, advanced audiences reduce waste and can lift sales, cross-channel measurement is essential, third-party validation matters due to platform bias, and current dual currencies plus clean room matching, while painful, enable price flexibility and innovation. Real-time optimization in TV is approaching, challenging marketers to move beyond delivery metrics.
The Outcomes Era: Tying Media Spend to Real Outcomes
Tom Laband of Adsquare argues the advertising industry is in an "outcomes era" where every marketing investment — brand or performance — must prove commercial impact. Performance measurement matured through affiliate marketing, CPC and programmatic systems, while brand activity historically relied on soft proxies; that distinction is collapsing as CFOs demand hard KPIs. Measurement is being complicated by signal erosion from GDPR, Apple’s App Tracking Transparency and the decline of third-party cookies. Partial fixes include clean rooms, CDPs, MMM and retail media (which embeds purchase outcomes in inventory), but most transactions still occur offline. Laband identifies the online-to-offline measurement gap as the key frontier and highlights AI-driven predictive audience models and synthetic control experiments as next steps to connect media dollars to real-world business outcomes.
