Digital Video is Set to Capture Nearly 60% of All TV/Video Ad Spend in 2025, CTV Rebounds to Double-Digit Growth in 2024, According to IAB

Sports, Live Streaming Events, and Programmatic Ad Tools Fuel CTV Growth

NEW YORK, April 28, 2025 /PRNewswire/ -- A resurgence in live events and sports programming on streaming platforms, coupled with the expansion of self-serve and programmatic ad tools, helped CTV rebound with 16% year-over-year (YoY) growth in 2024, according to IAB's "2025 Digital Video Ad Spend & Strategy Report: Part One."

Now in its twelfth year, the report, developed in partnership with Advertiser Perceptions and Guideline, provides a comprehensive snapshot of the U.S. digital video marketplace across CTV, social video, and online video, surfacing how and where ad dollars are flowing and why.

"2024 was a pivotal year for digital video advertising. With high-quality content moving to streaming, advancements in advertising technology, and an influx of new inventory accelerated growth for both consumers and advertisers," said David Cohen, CEO, IAB. "CTV is making it clear it's a go-to channel for both viewers and advertisers and is expected to continue growing along with social video and online video."

Digital Video Is Pulling Further Ahead of Linear TV, Solidifying Its Dominance
This year's findings underscore a clear shift in momentum as digital video is expected to capture nearly 60% of total TV/video ad spend in 2025, double its share from just five years ago. This growth builds on a major turning point in 2024, when it surpassed linear TV for the first time. Digital video ad spend rose 18% in 2024 to $64 billion and is projected to grow another 14% in 2025, reaching $72 billion—two to three times faster than total media overall.

"The video industry continues its transformative shift towards streaming driven by content, creators, technology, and improved measurement. However, it is important to acknowledge that ongoing economic uncertainty, including tariffs, geopolitical conflicts, and changing consumer confidence, the marketplace in 2025 is more difficult to predict than ever before," added Cohen.

All three types of digital video, CTV, social video, and online video, are driving the overall channel's trajectory, with each posting double-digit growth.

"CTV and social video are core pillars of a brand's comprehensive and integrated media strategy," said Chris Bruderle, VP, Industry Insights & Content Strategy, IAB. "Consumer attention has already moved to these platforms, and advertisers are meeting them there - not just for the scale, but for the ability to precisely target, measure performance across devices, and drive real business outcomes. These channels are now foundational to any effective media strategy."

CPG, Retail, and Pharma Drive Digital Video Ad Spend Growth Through 2025
As the digital video marketplace continues to grow, more categories are ramping up their ad spend to connect with consumers where they watch content the most. In 2025, most major categories are set to increase digital video ad budgets by double-digits with CPG (13%), retail (18%), and pharma (19%) leading the way. These categories are capitalizing on advanced targeting, including AI-driven personalization, real-time insights, and shoppable ad formats to drive deeper engagement and more immediate consumer action.

Programmatic Self-Serve Tools are Reshaping the CTV Ad Landscape for SMBs
CTV is no longer just for brands with big budgets–following the rise of programmatic self-serve tools, small and mid-size businesses are stepping into the spotlight. In 2025, most of the dollars flowing into CTV are coming from reallocations—primarily from linear TV (36%), social media (36%), and other digital channels like online video, paid search, and display. This shift reflects growing confidence in CTV's ability to deliver targeted, high-impact campaigns, now made even more accessible through programmatic and self-serve tools.

Cohen concluded, "The combination of self-service technology, accessible pricing, and the ability to link spend to outcomes has empowered small and mid-size businesses to get a piece of the CTV pie, making it easier and effective to promote, reach, and engage with audiences."
