CTV Growth Soars as UK Trust in TV Ads Rises
VideoWeek’s 'Week in Charts' roundup highlights multiple industry data points: Netflix’s UK ad-tier households grew 13.11% quarter-on-quarter in Q4 2025 (Barb’s Establishment Survey), driven by the Stranger Things finale; Disney+’s ad tier grew ~13% while Amazon Prime’s was largely flat. UK research shows rising trust in advertising across channels — TV trust rose from 33% in 2021 to 46% in 2025 (Credos) — while influencers remain the least trusted (25%). CTV viewers value convenience features such as starting a show from the beginning (77%), resuming where they left off (76%) and instant 'watch next' episode playback (76%) per Oliver & Ohlbaum. A study from the IPPR found BBC News is notably absent from ChatGPT answers. The roundup also notes broad downward pressure on agency and ad-tech stocks, Comcast’s relative resilience after Q4 results, Thomson Reuters’ 5% YoY Q4 revenue growth, Apple overtaking Google in market cap, and Amazon’s 14% stock fall after a large capex forecast.
Week in Charts: CTV Shares, Retail Media Shift, AI Ads
VideoWeek’s 'Week in Charts' highlights industry data and market moves: Pixalate data shows Samsung held the largest share of open programmatic CTV impressions in the UK (31%) in Q1 2026 while Roku led the US (36%), with Amazon Fire TV second in both markets. eMarketer forecasts China’s share of global retail media ad spend to fall from 44% (2026) to 42% by 2029 while the rest of the world rises from 20% to 22%; the US is expected to remain at ~36%. An IAB UK/MTM survey found half of UK consumers comfortable with AI-generated background images, but a majority uncomfortable with fully AI-generated people in ads. TiVo research shows in-car video is most commonly used to entertain children and is watched more often when parked (41.8%) than moving (31.7%). The piece also summarises recent stock movements affecting adtech and media companies.
German Court Invalidates Amazon Prime Price Adjustment Clause
Germany's Federal Court of Justice (BGH) ruled Amazon's 2022 Prime price increase invalid due to intransparent contract clauses, specifically clauses 5.2 and 5.3, which violated § 307 BGB. The court found customers were not adequately informed of their rights upon price changes, constituting an unreasonable disadvantage. As a result, Amazon must temporarily revert prices for members who joined before September 15, 2022 and have had continuous membership since then. Affected customers can claim refunds for up to three years, either individually or by joining the class action led by Verbraucherzentrale NRW, which has about 145,000 registered claimants. A separate class action is ongoing regarding Amazon's introduction of ads in Prime Video, which users can avoid for an additional fee. Amazon will inform affected members before their next payment. This ruling sets a precedent for similar cases against Netflix, Apple TV, and Wow.
