By MarkOTTPublished On August 15, 2025
Connected TV (CTV) roared back in 2024, posting double-digit gains and proving that streaming is no longer just a digital add-on—it’s becoming the centerpiece of brand strategy. According to the IAB’sAfter several years of strong growth, 2025 is shaping up to be a watershed year for Connected TV (CTV) and Over The Top (OTT) marketing. U.S. CTV ad spend is projected to reach $26.6 billion this year, up 13% from 2024, and digital video overall is on track to hit $72 billion—securing nearly 60% of all TV/video budgets.
At Over The Top Marketing, we’re seeing brands accelerate their streaming investments not just because audiences have shifted, but because the technology and targeting available in 2025 make campaigns more measurable, interactive, and cost-efficient than ever.
Why 2025 is Different
Shoppable TV Becomes Mainstream Interactive ad formats, once experimental, are now standard across major streaming platforms. Viewers can browse products and complete purchases without leaving the screen.
First-Party Data in the Spotlight With privacy changes limiting third-party tracking, advertisers are tapping into their own customer data to fuel OTT campaigns—unlocking higher personalization and ROI.
Cross-Screen Conversions Are Closing the Loop Campaigns now follow viewers from their living room TV to their mobile devices, delivering retargeted ads and purchase reminders within hours.
The Industries Leading the Charge
Retail, CPG, auto, and travel brands are fueling much of the growth, using CTV not just for awareness but as a full-funnel performance channel. These sectors are leaning heavily into AI-driven optimization, allowing campaigns to adapt in real time based on engagement and sales data.
Looking Ahead to 2026
If current trends hold, CTV ad spend could approach $30 billion in the U.S. by 2026, with OTT marketing accounting for two-thirds of all video ad spend. Expect:
More Live Event Streaming — from sports to concerts, unlocking premium, engaged audiences.
Deeper Retail Media Integrations — connecting CTV impressions directly to in-store and e-commerce sales.
Performance-Based Buying Models — shifting more budget to cost-per-acquisition and revenue-share deals.
Localized & Hyper-Targeted Campaigns — giving SMBs the same reach and precision as national brands.
Bottom Line
2025 isn’t just another growth year—it’s the year CTV becomes the dominant force in video advertising, and 2026 will take it even further. For brands working with Over The Top Marketing, the focus is clear: smarter targeting, interactive formats, and measurable outcomes that prove the power of streaming.
