Mastering Cross-Screen Video Advertising Measurement
Across the cross-screen era, advertisers face fragmentation of attention across TV, mobile, streaming and social platforms. The industry is shifting from simple metrics like reach and TKP to measuring the real impact of moving images, with progress in cross-media measurement led by AGF Videoforschung and Nielsen, and insights from Audienceproject, Pilot, Havas, and XAD Spoteffects. Key themes include hybrid data models that combine panels with census data, the importance of context and creative excellence, the need for targeting signals beyond basic demographics, and the drive to harmonize inventories and identity across channels. Real-time measurement, deduplicated reach, and attention-driven insights are highlighted as part of a broader move toward a unified cross-screen measurement framework, with RTL+ and Joyn cited as examples of ongoing harmonization.

Recent verified developments and strategic activity across this market segment.
Former Telekom Media Chief: Advertisers Must Price in Bots
At the AGF Forum in Frankfurt, Norman Wagner, Managing Director of Pion3ers and former media chief at Deutsche Telekom, demonstrated live how easy it is to create a fully AI-generated magazine and generate fake traffic using bots. He argued that a majority of online content and traffic now comes from bots, making it extremely difficult for advertisers to measure true reach and effectiveness. Wagner believes that technology alone cannot solve the problem and instead advocates for 'common sense' and independent measurement. He suggests that walled gardens that do not allow independent verification should face a price discount. He also highlighted the potential of AI in contextual brand safety, noting that keyword-based negative lists incorrectly classify 70% of news environments as unsuitable.
Streaming UX: Key to Subscription Retention
A new analysis highlights that poor user experience (UX) is a major driver of streaming subscription cancellations. According to a study by CTAM and Hub Entertainment Research, 36% of viewers have cancelled a subscription due to UX frustrations, rising to 43% among under-25s. Gracenote data shows users spend an average of 14 minutes searching for content, with 49% saying they would cancel if search remains difficult. The Deloitte Digital Media Trends 2026 reports 39% of US users cancelled a subscription in the last six months because they couldn't find content quickly. As competition intensifies, providers are advised to improve content discovery, personalization, and navigation to reduce churn, which is at 6.3% monthly average in 2026.
