- ·The DrumData Neutrality
Neutrality has two tests, but vendors keep answering the easy one
Erin Lutenski, Head of Marketing at Decentriq, discusses the industry's conflation of two distinct neutrality questions following data platform acquisitions. The first question concerns data exposure, which technical measures like encryption and trusted execution environments can address. The second, harder question concerns incentives: who decides product roadmaps, measurement standards, and partner integrations, and whether a parent company's commercial interests will compromise the platform's neutrality. Using LiveRamp's acquisition by Publicis and the earlier case of Acxiom's acquisition by IPG, Lutenski argues that vendors often provide technical reassurances that do not resolve the underlying incentive concerns. She contends that governance policies are reversible and architecture alone cannot ensure neutrality. The article concludes by urging stakeholders to identify which question a neutrality statement actually answers.
- LiveRamp filed neutrality commitments with the SEC ahead of its acquisition by Publicis.
- Publicis is acquiring LiveRamp.
- LiveRamp was formed in 2018 after Acxiom split and IPG acquired Acxiom Marketing Solutions.

Brands Should Use Retail Media for AI-Led Discovery
Esme Robinson of Epsilon argues that as AI-powered search and shopping agents change how consumers discover products, brands should invest in retail media to control the product narrative within retailers' properties. Retailers' first-party data and structured product feeds increasingly inform AI recommendations, so brands that build richer, text-led pages and brand experiences inside retail media environments can influence signals used by AI assistants, improve visibility during peak buying seasons, and create co-branding and promotional opportunities at point of purchase.
- Esme Robinson of Epsilon authored an opinion piece discussing retail media and AI-led discovery.
- The article states AI-powered search (e.g., Google AI, ChatGPT-style platforms) is shifting consumer queries toward context-rich questions and acting as a gatekeeper for discovery.
- Retail media uses retailers' first-party shopper data and structured product feeds that increasingly inform AI agents' recommendations.

Shoppers Cut Non-essentials; Golden Quarter Competition Rises
A new Epsilon report, based on two Censuswide studies, finds UK consumer intent for the Golden Quarter at £17.9bn, but shows widespread caution: 71% of shoppers say they are cutting back on non-essential spending and 68% are seeking lower prices. The research also notes ad spend is forecast to reach £50bn this year while audience growth is minimal and average daily online time has fallen. Marketers plan to prioritise performance (79% of Q4 spend) and many expect H2 budgets and Q4 sales to be up, but the report warns conversion risk if demand proves softer than expected.
- Epsilon's report projects £17.9bn of UK consumer spending intent during the Golden Quarter.
- 71% of shoppers reported cutting back on non-essential purchases; 68% are looking for lower prices.
