CTV Ad Spend Forecast

Global CTV ad spending is forecast to reach $48 billion in 2025, a 33% increase from 2023, indicating that CTV is becoming a primary strategy in media budgets.

What Is Connected TV (CTV) and How Does It Differ from OTT?

Connected TV (CTV) refers to a television set or device that delivers streaming video over the internet, enabling advertisers to serve digital ads directly to living-room screens. This differs from over-the-top (OTT) services, which encompass any internet-delivered video regardless of screen type, including mobile, desktop, and smart TVs. Understanding this distinction clarifies why CTV ad campaigns focus on big-screen experiences and cord-cutter audiences.

What Defines Connected TV and Its Key Devices?

Connected TV comprises two main device categories—integrated smart TVs and external streaming devices—that enable internet connectivity on a television.

• Integrated Smart TVs include built-in apps for services like Netflix and Hulu.

• External Streaming Devices plug into HDMI ports to add internet streaming to any display.

• Gaming consoles and set-top boxes also qualify when used for video apps.

These devices support high-definition streaming, seamless app navigation, and automatic software updates, preparing marketers to deliver immersive, full-screen ad experiences. As more households adopt smart TVs and streaming sticks, the scale for connected-screen campaigns continues to expand.

How Does OTT Streaming Relate to Connected TV?

Over-the-top (OTT) streaming denotes the delivery of video content via the public internet, bypassing cable or satellite providers. While CTV specifies the television hardware, OTT describes the distribution channel. An OTT service like Disney+ can stream on mobile, web, or CTV devices, but only the CTV viewing context delivers the big-screen environment and associated viewing behaviors that advertisers leverage for longer dwell times and premium inventory.

How Has TV Consumption Evolved with Cord-Cutting and Streaming Growth?

As cord-cutting accelerates, traditional pay-TV subscriptions have declined by over 20 percent in five years, while CTV viewership has grown by more than 30 percent annually. Consumers increasingly prefer on-demand, ad-supported models (FAST) and premium subscription options. This evolution compels brands to reallocate budgets from linear schedules to dynamic, data-driven CTV placements that reach engaged audiences outside rigid broadcast time slots.

What Are the Top Benefits of CTV Advertising for Your Business?

CTV advertising combines the broad reach of TV with digital precision to support brand building and direct response. Brands can enhance campaign performance by targeting specific demographics, interests, and behaviors on the living-room screen while maintaining full control over viewability and completion metrics.

CTV's Impact on Marketing

CTV advertising offers several advantages, including the ability to drive incremental reach and conversions, precise targeting, and real-time campaign adjustments based on performance metrics.

How Does Precision Targeting and Audience Segmentation Work in CTV Ads?

CTV ads utilize device IDs, geographic data, and first-party customer segments to deliver relevant creative to defined audiences.

1. Demographic Targeting filters viewers by age, gender, and household income.

2. Behavioral Segmentation leverages streaming habits and app usage patterns.

3. Custom Audiences integrate CRM data for site retargeting and lookalike modeling.

These capabilities ensure your message reaches high-value viewers, driving improved relevance and reducing wasted ad spend compared to broad linear buys. Precise segmentation also lays the groundwork for more accurate attribution and ROI measurement.

Why Does CTV Advertising Deliver Enhanced Viewer Engagement and Brand Awareness?

CTV ads appear in full-screen, high-definition environments, which foster higher attention and completion rates than desktop or mobile video. Viewers engage 90–98 percent of the way through CTV ads, compared to 70 percent on other platforms. This immersion boosts brand recall and lift by up to 23 percent versus traditional TV, making CTV a powerful lever for driving awareness, consideration, and purchase intent simultaneously.

How Can Businesses Measure ROI and Performance with CTV Advertising?

CTV Advertising Benefits

CTV advertising allows for precise targeting, detailed measurement, and accurate attribution, enabling advertisers to optimize campaigns and measure their effectiveness through conversions.

How Does CTV Advertising Extend Reach Beyond Traditional Linear TV?

By tapping into cord-cutters and streaming-only households, CTV extends incremental reach that linear TV cannot capture. Ads can appear across multiple apps during peak streaming hours and in FAST channels that mirror broadcast networks without subscription fees. This incremental reach complements broadcast campaigns and helps brands connect with younger, digitally native viewers on the platforms they prefer.

How Does Programmatic CTV Advertising Work to Optimize Your Campaigns?

Programmatic CTV automates the buying and selling of ad inventory through real-time bidding, enabling advertisers to adjust budgets, creative, and audience segments instantly based on campaign performance and data signals.

Programmatic CTV Advertising

Programmatic CTV advertising utilizes automated software to buy and sell ad spots on connected TV platforms, enabling advertisers to target audiences with precision based on demographics, location, interests, and behaviors.

How Is Data Integration and First-Party Data Used in CTV Targeting?

Advertisers ingest CRM lists, website visitors, and loyalty program members into a data management platform (DMP) or DSP to create custom segments. This first-party data merges with device graphs and demographic datasets to match household IP addresses and device IDs. The result is hyper-relevant CTV targeting that aligns with known customer profiles and drives more effective cross-screen campaigns.

What Are the Best Practices for CTV Ad Formats and Creative Execution?

1. Use 16:9 aspect ratios or full-screen interstitial formats for maximum impact.

2. Include concise branding in the first five seconds to capture attention.

3. Leverage dynamic overlays or QR codes to bridge viewers to mobile or web experiences.

Implementing these best practices enhances completion rates and encourages viewer interaction, improving overall campaign performance.

Which Are the Leading CTV Advertising Platforms and Devices to Reach Your Audience?

An effective CTV strategy maps your target segments to the platforms and hardware they use most, ensuring optimal ad placement and frequency.

What Platform-Specific Advertising Features Should Businesses Leverage?

• Advanced demographic and household segment filters on Hulu.

• Purchase intent signals integrated into Amazon Fire TV ads.

What Are the Emerging Trends and Advanced Strategies in CTV Advertising for 2025?

The CTV landscape continues to evolve rapidly, with new ad formats, data innovations, and ecosystem integrations shaping next-generation campaigns.

How Are Interactive and Shoppable CTV Ads Changing Viewer Engagement?

Interactive and shoppable CTV ads embed click-to-shop overlays, QR codes, or voice-activated prompts directly into full-screen video. These formats boost engagement by 52 percent and shorten the path from awareness to purchase, seamlessly transitioning viewers from TV to e-commerce environments for immediate action.

What Role Does AI and Machine Learning Play in CTV Targeting and Optimization?

Artificial intelligence powers granular audience discovery, creative personalization, and bid optimization. Machine-learning models analyze viewing patterns to predict high-value impressions, adjust pacing in real time, and serve dynamic creative variations tailored to household profiles, boosting conversion lift while reducing wasted spend.

How Can Omnichannel and Cross-Channel Integration Enhance CTV Campaigns?

Unifying CTV with search, social, display, and linear buys creates a cohesive customer journey. By syncing frequency caps, creative messaging, and attribution across channels, brands reinforce key touchpoints and deliver consistent storytelling, which improves cross-screen recall and lifts overall campaign effectiveness.

What Are the Future Innovations and Projections for CTV Advertising?

1. Growth of FAST (Free Ad-Supported Streaming TV) platforms as premium ad inventory.

2. Contextual targeting that leverages real-time content metadata for brand safety.

3. Advanced clean-room collaborations for secure data sharing and attribution.

4. Expanded programmatic guaranteed deals and private marketplace buys.

These innovations promise more control, transparency, and creativity for advertisers seeking to stay ahead in a crowded streaming ecosystem.

How Can You Measure Success and Overcome Common Challenges in CTV Advertising?

While CTV offers powerful capabilities, brands must address measurement complexities and fragmentation to sustain scalable, high-performing campaigns.

How Do Attribution Models Work for CTV Advertising?

CTV attribution models link ad exposures to downstream conversions by matching device graphs, log-level data, and click-through events across screens. Multi-touch and incrementality testing frameworks help isolate CTV’s influence on sales and digital actions, ensuring marketers attribute value accurately and optimize accordingly.

What Are the Main Challenges in CTV Advertising and How Can They Be Solved?

• Fragmentation across apps and devices can be managed by leveraging unified platforms that offer cross-publisher buying and consolidated reporting.

• Ad fraud risks are mitigated through third-party verification services and enforcement of publisher transparency standards.

• Measurement inconsistencies resolve with server-to-server data collection and partnerships in secure clean-rooms that match first-party signals.

What Strategies Help Mitigate Ad Fatigue and Improve Viewability?

1. Implement frequency capping to avoid overexposure.

2. Rotate creative assets regularly to sustain interest.

3. Leverage day-parting and audience-based pacing for optimal ad timing.

These tactics balance reach and freshness, ensuring high completion rates and positive brand experiences.
