Rakuten TV Joins Barb Measurement

Executive Signal Summary

Rakuten TV Enterprise, the B2B arm of Rakuten TV (part of Rakuten Group), has signed up to be independently measured by Barb (Barb Audiences), the UK joint-industry audience measurement body. Effective immediately, Barb’s hybrid methodology will cover Rakuten’s UK ad-supported VOD inventory and FAST channels, allowing advertisers to compare its reach against broadcasters and major streamers using a recognised Joint Industry Currency. Initial Barb measurement (W2–5 2026) shows Rakuten TV reached roughly 2 million UK individuals and delivered meaningful incremental audiences: 54.6% of its viewers did not appear on other Barb-measured FAST platforms, and 11% did not watch major public-service broadcasters in the same period (rising to 27% of 16–24s). Rakuten TV said the move improves transparency and advertiser confidence in FAST/CTV buying; Stuart Keith (VP Global Ad Strategy & Partnerships) framed the signing as aligning measurement language across the industry.

High Confidence

Independent Barb measurement increases transparency and consistent cross-platform audience metrics for advertisers, addressing CTV/FAST fragmentation and improving media-buying confidence, but it is not a major industry-shifting policy or platform change.

Samsung Ads: Reach Gamers on CTV via ACR Data

Sean Smith, EMEA Gaming Lead – Sales at Samsung Ads, argues that gaming should be considered part of the TV ecosystem, not a separate channel. He highlights that console gamers average nearly six hours of play on CTV weekly, and that gamers often over-index on streaming and linear TV. With major game launches like GTA VI creating cultural moments, brands can reach gamers between gaming and streaming sessions via the home screen. Samsung's ACR data and first-party signals can identify TVs with connected consoles and optimize campaigns across linear, streaming, and gaming. The article emphasizes the need for unified measurement across all three modes to avoid under-reaching gamers.
