Nielsen CTV ad spend tracking launches in France for major streamers

The expansion of Ad Intel into France addresses a critical visibility gap for agencies managing budgets across fragmented domestic and global streaming services. By providing cross-platform data that includes both traditional broadcasters and SVOD giants, Nielsen enables more precise shifts in capital between linear and digital inventory. This move signals a maturation of the European ad market where siloed planning is no longer viable for brands seeking to optimize return on spend. Watch for the upcoming Italy launch to complete Nielsen's coverage of major Western European advertising hubs, potentially establishing a standardized regional benchmark for CTV investment.

Nielsen has been steadily building its CTV measurement footprint across Europe, with France representing a strategic addition to its Ad Intel portfolio. In early 2025, Nielsen launched its Ad Intel CTV tracking in the United Kingdom, covering platforms including ITVX, Channel 4, and Sky, establishing a template for the French rollout. The UK deployment provided competitive intelligence on ad spend shifts between broadcast video-on-demand and subscription streaming services, giving agencies a unified view of television advertising investment. That launch followed Nielsen's broader push to integrate streaming data into its legacy Ad Intel product, which had historically tracked only linear TV and digital display spending.

The French CTV advertising market has attracted significant investment from both domestic broadcasters and global streamers. TF1 launched its ad-supported streaming tier TF1+ in January 2024, reporting over 30 million monthly active users within its first year, making it one of the most-watched free ad-supported streaming services in France. Meanwhile, Canal+ announced in March 2025 that it would expand its ad-supported streaming offering across its European markets, signaling growing appetite for CTV inventory among premium European content providers. These platform expansions create the measurement demand that Nielsen's Ad Intel CTV module is designed to capture, as advertisers need cross-platform visibility to allocate budgets effectively.

Nielsen's competitive positioning in CTV measurement faces pressure from multiple directions. Comscore launched its vCE (valid campaign essentials) CTV measurement product in Europe in late 2024, offering cross-platform audience verification for streaming campaigns, directly competing with Nielsen's audience measurement capabilities. On the ad intelligence side, Pathmatics, an Amazon-owned ad analytics firm, expanded its CTV ad spend tracking to European markets in mid-2025, providing competitive intelligence on streaming ad placements that overlaps with Nielsen's Ad Intel offering. The inclusion of YouTube in Nielsen's French CTV tracking is notable given that YouTube remained the most-watched streaming platform on French connected TV screens in 2025, accounting for approximately 12% of total TV viewing time, according to Médiamétrie's annual streaming audience reports.
