The State of Digital Advertising in 2025
The IAB report, which utilizes self-reported revenue data from online advertising sellers, paints a picture of a robust but evolving market. The $294 billion total represents a healthy double-digit growth, yet the internal dynamics of that spending show clear winners and laggards. While search advertising, including the burgeoning field of AI-powered search, generated a massive $114 billion, its growth rate fell to 11% year-over-year. This is a noticeable deceleration from the 15% growth rate recorded in 2024, signaling that the search market may be approaching a stage of maturity or facing increased competition from alternative platforms.
In contrast, social media has emerged as the fastest-growing major category. Social ad revenue climbed to $117 billion, a staggering 32% increase that added $29 billion to the sector in a single year. This surge allowed social media to overtake search in total revenue within the IAB’s reporting framework, a milestone that reflects the changing habits of consumers who increasingly use social platforms for product discovery, entertainment, and even primary search functions.
The Drivers Behind Social and Video Dominance
The IAB attributes the 32% surge in social media revenue to several converging factors: the maturation of the creator economy, deeper commerce integration, and more sophisticated targeting and measurement tools. Social platforms have transitioned from simple networking sites into comprehensive ecosystems where users can discover a product via an influencer, research it through short-form video, and purchase it without ever leaving the app.
Digital video has followed a similar trajectory of accelerated growth. Revenue in this category reached $78 billion, growing by 25%—a significant jump from the 19% growth rate seen in the prior year. The rise of Connected TV (CTV) and the ubiquity of short-form video content on platforms like TikTok, Instagram Reels, and YouTube Shorts have made video an indispensable tool for advertisers seeking high engagement. As traditional linear television continues to decline, digital video has captured the diverted budgets of major brand advertisers.
Search Advertising: A Maturing Giant Facing New Challenges
Despite the slowdown in growth, search advertising remains a $114 billion powerhouse. However, the drop from 15% to 11% growth suggests a shift in the competitive landscape. For decades, search was the undisputed king of high-intent advertising. When a user searched for "best running shoes," they were at the bottom of the marketing funnel, ready to buy.
Today, that journey is more fragmented. Younger demographics, particularly Gen Z, are increasingly turning to TikTok or Instagram to search for recommendations, bypassing Google or Bing entirely. Furthermore, the integration of Generative AI into search engines—while promising—has introduced a period of uncertainty. While AI search can provide more direct answers, it also changes the nature of ad placements and user click-through behavior.
It is important to note that the IAB data represents the industry as a whole. While individual companies like Google reported a 17% increase in Search revenue in Q4 2025, the broader industry data suggests that smaller players and niche search providers may be feeling the squeeze more acutely, or that the rapid growth of the past few years is naturally leveling off.
The Rise of Commerce Media and Programmatic Advertising
Another standout performer in the 2025 report is commerce media. Reaching $63 billion with an 18% growth rate, commerce media—often referred to as retail media—now accounts for more than 20% of total digital ad revenue. Retail giants like Amazon, Walmart, and Target have leveraged their massive troves of first-party shopper data to build advertising networks that offer closed-loop measurement, showing advertisers exactly how an ad led to a sale.
Programmatic advertising also continues to dominate the backend of the industry. Revenue from programmatic channels increased by 20% to reach $162 billion. This growth indicates that despite ongoing concerns regarding privacy regulations and the phase-out of third-party cookies, the efficiency and automation provided by programmatic buying remain essential for large-scale digital campaigns.
The Creator Economy: From Campaigns to Continuous Programs
One of the most significant qualitative shifts noted in the IAB report is the evolution of the creator economy. In 2025, creator-led advertising reached $37 billion. Projections for 2026 suggest this will grow to $44 billion. The IAB highlights a fundamental change in how brands interact with influencers. Rather than engaging in one-off, campaign-based "influencer marketing," brands are moving toward continuous "creator programs."
This shift signifies a deeper integration of creators into the brand’s long-term marketing strategy. Creators are no longer just mouthpieces for a product; they are becoming essential partners in content production and brand storytelling. This transition is a major contributor to the growth of social and video ad spend, as creator content is natively designed for those formats.
A Chronology of Digital Advertising Trends (2022–2026)
To understand the current state of the market, it is helpful to look at the timeline of digital advertising’s evolution over the last several years:
- 2022-2023: The Privacy Pivot. The industry grappled with Apple’s App Tracking Transparency (ATT) and the looming threat of Google’s cookie deprecation. Ad spend slowed as marketers sought new ways to measure performance.
- 2024: The AI Integration Phase. Search engines began heavily integrating Generative AI, and social platforms used AI to enhance their recommendation algorithms. Search ad growth held steady at 15%.
- 2025: The Social and Video Surge. Social media growth skyrocketed to 32%, overtaking search in total revenue within the IAB report. Total digital ad revenue hit $294 billion.
- 2026: The Year of the Continuous Creator. Projections suggest the creator economy will hit $44 billion as brands move away from tactical campaigns toward permanent creator-led strategies.
Expert Analysis and Industry Implications
The data from IAB and PwC suggests that we are entering a "post-search" era—not an era where search is irrelevant, but one where it is no longer the primary engine of growth. David Cohen, CEO of IAB, has previously noted that the "blurring of lines" between different ad categories is a defining feature of the current market. Because a single ad can be categorized as social, video, and commerce media simultaneously, the traditional silos of marketing budgets are breaking down.
For marketers, the implications are clear: diversification is no longer optional. A strategy that relies solely on search intent may miss the vast discovery-driven audiences on social and video platforms. Furthermore, the rise of commerce media suggests that "downstream" data—knowing what people actually buy—is becoming as valuable as "upstream" data—knowing what people search for.
Broader Economic and Technological Impact
The slowing growth of search relative to social and video also reflects broader technological shifts. As mobile devices become the primary screen for the majority of global users, the formats that perform best on mobile—short, vertical video and interactive social posts—are naturally attracting more capital.
Additionally, the regulatory environment is playing a role. Privacy-centric changes have made traditional search tracking more difficult, whereas social platforms often have logged-in environments that provide more stable, albeit "walled garden," data for advertisers. This has made social media a safer bet for many brands looking for reliable attribution in a privacy-first world.
Looking Ahead: 2026 Projections and Industry Discourse
The IAB’s 2026 outlook remains optimistic, with continued growth expected across the board, albeit with social and video likely maintaining their lead in growth rates. The industry is closely watching how AI search will evolve and whether it can re-accelerate the search category by providing more high-value, conversational ad opportunities.
To further analyze these findings, the IAB has scheduled a webinar for April 21 at 1 p.m. ET. The event will feature experts from the IAB, PwC, and Madison & Wall, who will provide a deeper dive into the data and discuss the long-term strategic shifts required for brands to thrive in this new landscape. As the digital ad market approaches the $300 billion mark, the competition for consumer attention has never been more intense, nor has the need for data-driven agility been more paramount.
