Connected TV Advertising in 2026: A Complete Guide for Marketers

If you've watched a show on Hulu, streamed a game on Peacock, or pulled up YouTube on your living room TV, you've already experienced connected TV. And if you've seen an ad during any of those sessions, you've experienced CTV advertising. What was once a niche digital experiment has become one of the most important channels in modern media planning—and in 2026, it's no longer optional for brands that want to reach audiences where they actually watch.

This guide explains what CTV is, how it works, why it's grown so quickly, and how to approach it strategically as part of a broader media mix.

What Is Connected TV?

Connected TV (CTV) refers to any television set that accesses content via an internet connection, either through a built-in interface or a third-party streaming device. Unlike traditional broadcast or cable TV, CTV supports app-based, on-demand viewing and allows for dynamic ad insertion based on viewer behavior and data.

What makes CTV distinct as an advertising channel is its combination of two things that historically didn't coexist: the immersive, full-screen format of television, and the targeting, measurement, and optimization capabilities of digital advertising.

Which devices count as CTV?

CTV encompasses a wide range of hardware:

Smart TVs have built-in streaming platforms (Samsung Tizen, LG webOS, Vizio SmartCast) that allow direct access to streaming apps without additional hardware.

Streaming devices like Roku, Amazon Fire TV, Google Chromecast, and Apple TV connect via HDMI and turn any TV into a streaming-capable screen.

Gaming consoles like PlayStation and Xbox function as entertainment hubs, with full access to streaming apps alongside gaming.

Set-top boxes from cable providers (Xfinity Flex, Spectrum TV Stream) increasingly support streaming content in addition to live television.

All of these devices share a key characteristic: they deliver content through apps over the internet, which enables dynamic ad serving—something their linear predecessors couldn't do.

CTV vs. OTT: Clearing Up the Confusion

These terms are frequently used interchangeably, but they describe different things.

OTT (Over-the-Top) refers to video content delivered over the internet, regardless of what device it's viewed on. If you watch Netflix on your phone, that's OTT.

CTV refers specifically to OTT content viewed on a television screen via an internet-connected device. If you watch Netflix on a Roku, that's both OTT and CTV.

The practical distinction matters for advertisers: CTV implies a television screen environment—full-screen, often shared viewing, high attention—which is meaningfully different from OTT on a mobile device. When buying CTV inventory, you're specifically targeting the living room experience.

It's also worth knowing that when purchasing ad inventory across streaming, OTT, CTV, and FAST (free ad-supported streaming TV) channels, these are typically grouped under "streaming" by most platforms and buying tools.

How CTV Advertising Works

CTV campaigns follow a process similar to digital advertising, adapted for the television environment:

• Audience definition: Advertisers identify target audiences using first- and third-party data—demographics, behaviors, purchase intent, geographic location, or CRM segments.

• Campaign setup: Budgets, objectives, and flight dates are established based on whether the goal is brand awareness, conversions, app installs, or re-engagement.

• Creative deployment: Video ads are formatted for streaming environments. CTV supports standard formats (15–30 second pre-roll and mid-roll) as well as newer interactive formats.

• Ad delivery: Ads are served programmatically or through direct publisher relationships within streaming content across platforms and apps.

• Measurement and optimization: Performance is tracked in real time (site visits, conversions, completion rates, incremental lift) and campaigns are adjusted mid-flight based on results.

This last step is what fundamentally distinguishes CTV from linear TV: the ability to see what's working and adjust while the campaign is still running.

The Growth of CTV: Where It Stands in 2026

CTV advertising has grown faster than almost any channel in the history of media buying. To understand where it sits today, it helps to see the trajectory:

• 2014: ~$1 billion in U.S. CTV ad spend, driven by early smart TV adoption

• 2018: ~$3.5 billion, as ad-supported streaming began to expand

• 2020: ~$8 billion, accelerated sharply by pandemic-driven streaming behavior

• 2022: ~$17.4 billion, following Netflix and Disney+ launching ad-supported tiers

• 2024: ~$25 billion, as FAST inventory expanded significantly

• 2026: ~$38 billion estimated, with CTV comprising over one-third of all U.S. TV ad spend

This growth is being driven by two forces working in parallel: consumers continuing to shift viewing from linear to streaming, and advertisers following that audience migration with their budgets.

By the end of 2026, over 80 million U.S. households are expected to use non-pay TV services. Younger demographics (the 18–34 cohort) consume streaming content at roughly three times the rate of traditional television. And with more platforms launching or expanding ad-supported tiers, the amount of available inventory continues to grow.

Key Benefits of CTV Advertising

Precise audience targeting

CTV moves beyond the broad demographic targeting of linear TV. Advertisers can reach audiences based on:

• Demographics and life stage: age, income, household composition, parental status

• Behavioral data: browsing history, app usage, purchase behavior

• Geographic targeting: national, regional, or hyper-local

• First-party CRM data: re-engage lapsed customers, upsell existing ones, or exclude current customers from acquisition campaigns

• Lookalike modeling: reach new audiences that resemble your highest-value customers

Cross-device integrations extend CTV exposure into follow-up touchpoints on mobile, desktop, or social, significantly improving conversion rates compared to a single-channel approach.

Measurable performance outcomes

CTV delivers digital-grade reporting that linear TV has never been able to match. Key metrics include:

• Cost per visit (CPV): the cost of driving a website visit attributable to ad exposure

• Cost per acquisition (CPA): the cost of converting a prospect into a customer

• Return on ad spend (ROAS): revenue generated per dollar of ad spend

• Incremental lift: conversions or actions driven by the campaign, isolated from organic behavior

• Completion rates: percentage of viewers who watched the full ad

• View-through conversions: actions taken after seeing but not clicking an ad

This level of attribution allows CTV to be evaluated alongside paid search and social on the same performance terms, a meaningful shift from the impression-based metrics that defined TV advertising for decades.

High viewer engagement

CTV ads run in a full-screen, typically non-skippable environment during long-form content on the largest screen in the household. This produces engagement rates that digital formats struggle to match:

• Viewability typically exceeds 90%, well above desktop or mobile video

• Completion rates are higher than most other digital video formats

• Ad breaks are generally shorter than linear TV, meaning each spot receives more focused attention

Newer formats are raising the bar further. Pause ads—which appear when viewers pause content—have been shown to drive a 34% lift in ad recall. Rewarded ads, which offer incentives like ad-free viewing in exchange for completing a full ad, create high-attention environments with minimal friction. Engagement rates for interactive CTV formats reached 1.94% in Q2 2025, nearly doubling year-over-year.

Accessibility for brands of all sizes

CTV has meaningfully lowered the barrier to entry for TV advertising. Self-serve platforms allow campaigns to launch with modest budgets, geo-targeted to specific markets, without requiring a traditional media buy or agency relationship. Average CPMs in 2026 range from approximately $25 to $65 depending on targeting specificity and inventory quality—accessible for regional brands and growing DTC companies that would have been priced out of linear TV entirely.

Interactive and Shoppable CTV: The Fastest-Growing Format

CTV advertising is no longer limited to passive video. Interactive and shoppable formats have moved from experimental to mainstream, and they're changing how advertisers think about the channel's role in the funnel.

Key interactive formats include:

QR-based shoppable overlays that allow viewers to scan with their phone and go directly to a product page or offer.

Clickable remote-based experiences that let viewers interact with an ad using their TV remote — browsing products, requesting information, or adding items to a cart without leaving the viewing experience.

Second-screen integrations that trigger companion content on a viewer's phone when an ad runs on their TV.

The performance data behind these formats is compelling: interactive ads drive a 36% increase in unaided brand recall, a 33% lift in brand affinity, and measurable foot traffic increases of 13% compared to standard video formats. 41.8% of U.S. marketers now use interactive or shoppable formats across CTV and social, a figure that has grown rapidly in the past two years.

Retail Media and CTV: The Biggest Convergence of 2026

One of the most significant developments in CTV advertising is its integration with retail media networks. This convergence addresses CTV's historical limitation—attribution—in a way that changes its value proposition for performance advertisers.

Amazon Prime Video connects ad exposure directly to purchase behavior through its closed-loop commerce ecosystem, reaching over 315 million global ad-supported viewers. Walmart's acquisition of Vizio has enabled closed-loop measurement using first-party shopper data tied directly to in-store and online purchases. Grocers like Albertsons are extending their retail media capabilities into streaming environments, allowing CPG brands to tie CTV impressions to basket-level purchase data.

The result is that advertisers can now measure TV advertising the way they measure performance digital campaigns: tying impressions directly to revenue outcomes rather than relying on probabilistic attribution models. Retail media-driven CTV ad spend is growing roughly three times faster than retail search, signaling how quickly the category is maturing.

What Advertisers Need to Know About the CTV Landscape

Linear TV still controls a meaningful share of inventory

Despite streaming's growth, approximately 25% of ad-supported streaming content—particularly on FAST channels like Pluto TV and Tubi—can only be accessed through linear TV buys. Brands that want full reach within specific programming often need to engage both linear and streaming buying strategies, not one or the other.

CTV fraud is a real challenge

The rapid growth of CTV inventory has been accompanied by an increase in fraudulent activity. Bot fraud in CTV rose 69% in 2022 compared to the prior year, with identified CTV fraud schemes increasing 300% since 2020. Fraudulent tactics include botnets manipulating inventory and hijacking legitimate CTV device sessions to inflate impression counts. The most effective safeguard is outcome-based measurement; because bots cannot generate genuine consumer actions like site visits or purchases, tying campaign success to real outcomes rather than impressions provides a natural fraud filter.

Programmatic isn't the only—or always the best—path

While programmatic buying has transformed digital advertising, CTV operates somewhat differently. Premium CTV inventory is concentrated among a relatively small number of major publishers, many of whom are moving toward direct sales relationships to maintain control over pricing and the viewer experience. For advertisers seeking premium placements (live sports, major originals, tentpole moments), direct publisher relationships often provide better inventory, more transparency, and stronger performance than open auction programmatic buys.

Platform consolidation is reshaping buying dynamics

The CTV landscape is consolidating rapidly. Disney+ and Hulu are being integrated into a single platform, combining two of the largest ad-supported streaming audiences and creating one of the most significant combined CTV offerings in the market. Potential acquisitions involving Warner Bros. Discovery could further concentrate premium inventory. The Nexstar-Tegna merger has created a local TV powerhouse with 265 stations. For advertisers, consolidation simplifies buying in some respects but also concentrates negotiating leverage among fewer platforms, making it increasingly valuable to establish strong direct relationships with key publishers early.

CTV in Your Media Strategy

CTV works best not as a standalone channel but as an integrated component of a broader strategy. It occupies a unique position in the media mix: it can serve both upper-funnel brand-building goals and lower-funnel performance objectives, often within the same campaign.

Used alongside linear TV, CTV extends reach into households that have cut the cord or never subscribed to cable. Used alongside paid search and social, CTV reaches audiences earlier in the consideration journey, priming them to respond when they encounter the brand elsewhere. Used with first-party CRM data, it enables retargeting of lapsed customers or high-value segments at scale—one of the most cost-efficient applications of the channel.

A few principles that hold across campaign types:

Prioritize interactivity where it fits. Engagement rates for interactive formats are growing fast—static video is increasingly the floor, not the ceiling.

Manage cross-platform frequency. As inventory expands across more platforms, the risk of overexposure to the same viewer increases. Frequency caps and deduplication across platforms are essential.

Test emerging formats. Pause ads and rewarded ads offer high-attention environments outside the traditional ad pod. Both are underutilized relative to their performance data.

Balance linear and streaming. Linear still delivers unmatched reach for live events and broad awareness campaigns. Streaming delivers the targeting precision and measurement that performance campaigns require. The most effective strategies use both deliberately rather than defaulting to one.

Measure incrementality, not just impressions. The ability to run holdout tests and geo-splits—proving that a campaign caused a lift in conversions rather than just correlating with it—is one of CTV's most important capabilities. Build that into campaign planning from the start.

Frequently Asked Questions

What's the difference between CTV and OTT? CTV refers to the device (an internet-connected television). OTT refers to the content (video delivered over the internet regardless of device). All CTV viewing is OTT, but not all OTT viewing is CTV (a phone or tablet watching streaming content is OTT but not CTV).

Can small businesses advertise on CTV? Yes. Self-serve platforms and programmatic buying have made CTV accessible at a wide range of budget levels. Entry-level campaigns can launch with geographic targeting to control costs, and many platforms offer CPMs starting in the $20–$40 range for broad inventory.

What metrics should I track in a CTV campaign? The most meaningful metrics are outcome-based: site visits, conversions, app installs, and incremental lift. Completion rates and viewability are useful supporting metrics. CPMs and impressions alone don't tell you whether a campaign actually drove business results.

Is CTV better for brand awareness or performance? Both. CTV's full-screen, high-attention format makes it effective for brand building. Its targeting capabilities and measurable attribution make it viable for direct response. Most sophisticated advertisers use it for both simultaneously, running creative designed to drive immediate action while also building longer-term brand recognition.

How does CTV fraud affect campaign performance? Bot fraud inflates impression counts without generating real viewer exposure. The best defense is measuring outcomes rather than impressions—genuine consumer actions like site visits or purchases can't be faked by bots. Buying directly from publishers rather than through open exchanges also reduces fraud exposure.

What does it cost to advertise on CTV in 2026? Average CPMs range from approximately $25 to $65, varying by targeting specificity, platform, and content type. Premium inventory like live sports or high-demand originals commands higher rates. Programmatic and self-serve options allow more budget control for smaller advertisers.

Is Netflix a CTV platform? Yes. Since launching its ad-supported tier in 2022, Netflix has become part of the CTV advertising ecosystem, offering inventory through select programmatic and direct buying channels.
