Paramount+ Plans Short-Form Feed; CMA Proposes AI Opt-Out

VideoWeek's Week in Review highlights three main developments in ad-supported video and streaming. Paramount is exploring a short-form feed for Paramount+ on mobile, aiming to quickly build a library of clips—reportedly targeting around one million entries—with user-generated content appearing in internal planning. YouTube/BARB measurement efforts faced a setback after Barb and Kantar Media were compelled to suspend a service comparing YouTube channel viewership with other TV channels, following cease-and-desist letters citing terms-of-service concerns. In the regulatory arena, the UK CMA floated a proposal allowing publishers to opt out of content being used to train Google's AI tools and AI Overviews without withdrawing from standard search, signaling potential shifts in AI data usage and compensation discussions. The CMA’s ability to intervene stems from its designation of Google as having Strategic Market Status in the UK.

Ad Tech Faces AI Regulations and Market Resilience

ExchangeWire’s digest highlights growing regulatory scrutiny and platform-driven reinvention across ad tech. The UK Competition and Markets Authority has proposed measures to let publishers opt out of having their content used in Google’s generative AI Overviews or require separate training models. Meta plans to nearly double its AI investment while testing premium subscription tiers across Instagram, Facebook and WhatsApp that include enhanced AI features. The Advertising Association/WARC report shows UK ad spend resilience, rising 11.4% YoY in Q3 2025 to £12.5bn. Legal and commercial tensions are rising: YouTube creators expanded a copyright lawsuit to include Snap over alleged use of creator videos for AI training, and Google is rolling out shoppable connected‑TV ad formats tied to Demand Gen campaigns. U.S. ICE issued an RFI on big data and ad tech tools for investigative use.

UK Pushes Google for Publisher AI Opt-Out Options

UK regulators are pressing Google to give publishers and users more control over generative-AI features, including proposals from the Competition and Markets Authority (CMA) to let publishers opt out of having their content included in Google’s AI Overviews or used to train separate AI models. Google said it already offers controls and is considering additional opt-out options. Separately, Google issued a legal cease-and-desist to Kantar Media, forcing suspension of a joint project with Barb to measure YouTube viewing alongside traditional TV and streaming, citing concerns over data access, API use and creator attribution. Market data from the Advertising Association/WARC shows UK advertising spend rose 11.4% in Q3 2025 to £12.5bn, with digital channels at 83% of spend and forecasts that TV VOD will be the fastest-growing channel in 2026.
