Adform Joins ISBA, Pioneering Digital Sovereignty for Advertisers
Adform has become the first Demand‑Side Platform (DSP) to join ISBA’s Partner Programme, marking a strategic move to promote digital sovereignty and greater advertiser control for UK brands. ISBA, the representative body for British advertisers, and Adform say the partnership aims to increase transparency, accountability and alternatives to so‑called Walled Gardens. Adform positions itself as a global, independent DSP with European heritage emphasizing privacy and data ownership. In parallel, Adform is supporting the Alliance of Media Independents and sponsoring The Indie Agency Club at MAD//North. ISBA’s director of media Stephen Chester and Adform’s UK country manager Phil Acton provided statements underscoring the partnership’s focus on verifiable performance, advertiser control over data, and the open web as an alternative to legacy platforms.
An independent DSP joining ISBA signals momentum for advertiser-focused alternatives to Walled Gardens and supports transparency/data ownership debates in the UK, but is not an industry‑shifting technical or policy change.

Agency Fees in Creator Deals Pose Transparency Challenge
A new Future of Marketing Briefing from Digiday highlights growing concerns over hidden agency fees in creator marketing. A survey by the Incorporated Society of British Advertisers (ISBA) found that only 42% of marketers report fully transparent agency fees for creator work. Consultants like TrinityP3 warn that bundled deals can leave as little as 35% of budget for talent, compared to 60% when billed line-by-line. The Association of National Advertisers (ANA) reports agencies take an average 30% of influencer spend, with only 39% of agreements transparent. Experts argue that as creator budgets grow, the lack of itemized fees obscures value, leading to calls for greater accountability and measurement. The briefing also covers Diageo's creator recruiting strategy via Martha's Vineyard activations and other industry news.

This AI-powered platform simplifies campaign setup with DVA+ (including Performance Plus and Brand Plus) and Full-Funnel Campaigns, unifying Sponsored Display, Sponsored TV, and programmatic buying. The Agent offers natural language targeting, analytics, and AI guidance, with US tests showing a 25% increase in unique customers and over 10% lower cost per impression.

Meanwhile, Walt Disney is planning a major restructuring of its television operations, shifting focus from legacy cable and broadcast channels toward streaming-centered organization, led by Debra O'Connell, chairman of Disney Entertainment Television. The plan consolidates divisions like ABC Entertainment, 20th Television, Hulu Originals, and aims to reduce duplicated roles and align budgets with streaming metrics, following declining affiliate fees and cord-cutting. Hundreds of layoffs are expected, with further cuts in legal, HR, and tech departments, reflecting an industry-wide trend toward streaming-first strategies.
