Summary of Key Digital Developments in 2025 and Looking Ahead to 2026

A Pivotal Year Redefining the Digital Ecosystem

The year 2025 marked a transformative turning point in the digital ecosystem. It was far from a period of minor adjustments; instead, it was characterized by fundamental disruptions that significantly reshaped the balance of power among market players.

Advertising investments in Commerce Media surpassed those in television, content creators emerged as true media powerhouses, and the combination of data and Artificial Intelligence (AI) accelerated an unprecedented shift in the industry’s dynamics.

For WPP Media, understanding these trends is critical to develop winning strategies for 2026.

The Three Major Transformations of 2025

Commerce at the Center: Transaction Becomes the New Heart of Marketing

• A seismic economic shift: In 2025, Commerce Media emerged as the new epicenter of global advertising investments, overtaking television. Transactions are no longer the endpoint but have become the core of the marketing process, with a clear dominance of Retail Media.

• “Commerce Engine” Platforms: Industry giants such as Meta, TikTok, and Amazon have further integrated commerce into their platforms, transforming consumer intent into direct action. For brands, the challenge now lies in delivering a seamless and high-performing shopping experience across a multitude of touchpoints.

• The end of the linear funnel: According to WPP’s How Humans Decide study, 84% of purchase decisions are influenced by a “pre-existing brand preference” (Brand Priming). As a result, marketing efforts must prioritize proactively building this preference well before the point of conversion.

Audience Fragmentation: Scattered Content, Complex Measurement

• A fragmented video landscape: The dominance of linear TV is giving way to streaming platforms and fragmented content. Advertising budgets have followed audiences to these emerging channels, requiring brands to carefully orchestrate their strategies to effectively engage consumers.

• The rise of content creators: Content creators have solidified their role as media powerhouses, producing events that rival traditional media in both audience size and value. They have become critical drivers of conversion, embodying trust and social proof.

• The challenge of video measurement: This extreme fragmentation has made measuring video performance increasingly complex. The key question in 2025 was, “What is the true, deduplicated reach of my campaign across all these touchpoints?” Médiamétrie has addressed this challenge with its new TV & Video Watch household audience measurement, which integrates data from platforms like YouTube, Netflix, and Amazon.

Data and AI: Catalysts of Power Imbalance

• AI as a tool for consolidation: By 2025, AI and data had evolved from mere optimization tools into the bedrock of a new power dynamic. Major platforms leveraged a virtuous cycle—more data leads to better AI, which attracts more users, generating even more data—further cementing their dominance.

• The cookieless era and “Walled Gardens”: The strategic consolidation of “walled gardens” proved to be a significant win for platforms with access to billions of first-party data signals. As targeting on the Open Web becomes increasingly complex, these closed ecosystems offer advertisers reliable and effective solutions.

• The growing threat of disintermediation: AI has accelerated disintermediation, particularly through Large Language Models (LLMs) and Google’s “AI Overviews” (not yet available in France due to regulatory restrictions). These tools intercept the customer journey, reducing visibility into user behavior and intent. Automated campaign optimization tools like Performance Max and Advantage+ have shifted significant control to platform algorithms, increasing advertisers’ reliance on these systems and diminishing their direct influence.

WPP Media: Mastering Complexity for 2026

In response to these evolving dynamics, the digital ecosystem is striving to reinvent audience targeting in a post-cookie world (through contextual targeting and data clean rooms) and regain control over performance measurement. AI-enhanced Marketing Mix Modeling (MMM) 2.0 is emerging as a strategic cornerstone, complemented by tactical studies.

For 2026, success will not hinge on mastering a single lever but on the ability to orchestrate cohesive and effective experiences in a hybrid, ever-changing, and complex environment. Value is no longer derived from simply adding levers together but from how they are orchestrated.

With cutting-edge solutions like the Open Media Studio platform and the DPAM process (Discover-Plan-Activate-Measure), WPP Media is ideally equipped to help brands thrive in this new landscape. By mastering the art of orchestration, we will deliver measurable, long-term growth.
