Digital TV Advertising: What It Covers and How to Buy It

Streaming took 49% of US TV viewing in July 2026, against 19.5% for broadcast and 18.7% for cable, according to Nielsen’s Gauge, the latest edition published as of mid-October. YouTube alone had a record 14.2% of all TV viewing. Streaming first passed broadcast and cable combined in May 2025.

Ad money moves more slowly. The IAB expects US advertisers to spend $81.9 billion on digital video in 2026, up 11%, including $29.3 billion on connected TV, and puts digital’s share of combined TV and video budgets at 61%, up from 58%. More than half of the growth in CTV spending comes out of linear budgets. And because much streaming carries no ads, broadcast and cable still had 51.8% of ad-supported viewing in the second quarter of 2026, Nielsen’s ad-supported Gauge showed.

Digital TV advertising means TV ads bought with data and software rather than a rate card alone. It covers four products, each bought and measured differently.

What digital TV advertising covers

IAB Europe’s CTV definitions framework defines the terms. In practice they work like this:

• Programmatic linear. Scheduled broadcast and cable TV bought through software that picks networks and time slots against audience data. Everyone watching the program sees the same ad. EMARKETER forecasts $8.69 billion of US programmatic linear spending in 2026. Our piece on Comcast’s biddable linear TV shows one example.
• Addressable linear. Different households watching the same live program see different ads, swapped in through cable or satellite set-top boxes. Go Addressable, the trade group whose participants include Comcast, Spectrum, DIRECTV, DISH and Ampersand, put their combined addressable footprint at 69.5 million US households in 2025.
• Connected TV (CTV). Ads in streaming apps watched on a TV set, such as Hulu, Netflix’s ad plan, Prime Video and YouTube. Our CTV and OTT guide explains the difference between the device and the delivery.
• Free ad-supported streaming TV (FAST). Scheduled channels streamed free over the internet and paid for by ads, such as Pluto TV and the live channels on the Roku Channel and Tubi. The category is consolidating: Fox, which owns Tubi, agreed in June 2026 to buy Roku in a deal valuing it at about $22 billion including debt, which shareholders approved in October and regulators are still reviewing.

How each type is bought

• Programmatic linear is sold through private marketplaces and guaranteed deals. DIRECTV opened its satellite inventory to programmatic buyers in January 2025, and Comcast followed in October 2025.
• Addressable linear is bought from each provider or through partners that combine them. For planning, Go Addressable’s data partners supply household counts with duplicates removed.
• CTV is mostly programmatic. About 84% to 88% of US CTV ad spending runs through programmatic channels, and only about 18% to 19% through open auctions, MediaPost reported, citing industry estimates. Netflix said in May 2026 that its ad plan reaches more than 250 million monthly active viewers worldwide, with pause and live ads buyable through DSPs from summer 2026 in the US and Canada.
• FAST ad time is sold in one of two ways, according to Amagi, a FAST technology vendor: the platform sells all of it and shares revenue with the channel owner, or the two split the ad time and each sells its own.

Smaller advertisers can start in self-serve tools. Disney Campaign Manager sells Hulu and Disney+ ads with a minimum of $500 per campaign. Comcast’s Universal Ads advertises no minimum spend. Vibe, a self-serve CTV platform, starts at $50 a day. Our piece on CTV and search covers how TV shows up in search demand.

How digital TV advertising is measured

Most national TV deals are still traded on Nielsen audiences, an estimated 80% to 90% of the volume, MRWeb reported. Nielsen’s Big Data + Panel measurement, which adds set-top-box and smart-TV data from 45 million households to its panel, won Media Rating Council accreditation in January 2025, which the council reaffirmed in May 2026. In September 2026 the US Joint Industry Committee re-certified Comscore, iSpot and VideoAmp as alternative national currencies for 2026 to 2028.

Even the Gauge is disputed. Nielsen delayed its February 2026 edition after some streaming clients objected to new audience estimates that lifted broadcast’s share, then released it on the old method, The Desk reported. Read it for direction rather than precise shares.

CTV impressions can be matched to households and then to site visits or sales, but imperfectly. Only 57% of buyers have high confidence in inventory transparency, knowing where their ads ran, even through the most trusted CTV buying methods, and 33% for open exchanges, according to the IAB’s 2026 video report, as PPC Land reported. Pixalate’s monthly index of US open-programmatic streaming TV ad spending put the share going to phones and tablets at 43% in June 2026 and 21% in July, MediaPost reported. The most reliable test is a geographic holdout: run the campaign in some regions, not in comparable ones, and compare sales.

How digital TV differs from online video

Online video and digital TV often share platforms, but the exposure differs. The MRC counts an online video ad as viewable when half its pixels are on screen for two continuous seconds. A TV ad fills a shared screen: Nielsen found that 47% of linear and connected TV viewing involves more than one person at a time.

Attention measures still favor the TV set, though the gap is narrowing. Adelaide’s attention scores put linear TV at 56.2 and online video at 49.7 in the second quarter of 2026, against 52.7 and 37.6 in the first quarter of 2025, EMARKETER reported. In TVision’s panel, prime-time ads in the top premium streaming apps scored 26.2% on its attention measure in the second half of 2025, against 17.6% on YouTube, MediaPost reported.

YouTube sits on both sides, and Google Ads lets you target its TV screens device type separately. Creative differs too: a 30-second TV spot can tell a story with sound, while online video has to earn attention before a skip or a scroll. Our guide to traditional and digital marketing covers the wider comparison.

How to start with digital TV advertising

• Start with the goal. Linear suits broad reach, live sport and news. CTV suits younger viewers, frequency control and site-visit measurement.
• Buy TV screens, not a label. Ask what share of impressions ran on TV sets, and prefer deals with named apps over open-auction CTV.
• Cap frequency on every platform. One household can see your ad on Hulu, YouTube and a FAST channel in an evening.
• Set up a holdout before launch. Pick test and control regions and agree the metric in advance.
• Make TV-grade creative. Shoot or animate for the set, then cut down for phones.

Planning reach and running those tests is performance marketing work, and producing spots for both screens is a motion graphics and animation job.

Frequently Asked Questions

What is digital TV advertising?

Digital TV advertising is TV advertising bought, delivered or targeted with data and software rather than a schedule and rate card alone. It covers programmatic linear TV, where software buys scheduled broadcast and cable spots; addressable linear, where different households see different ads in the same program; connected TV ads in streaming apps; and free ad-supported streaming channels such as Pluto TV.

Is digital TV advertising the same as CTV advertising?

No. Connected TV advertising is one part of it, covering ads in streaming apps watched on a TV set. Digital TV advertising also includes scheduled broadcast and cable TV when it is bought programmatically or targeted by household through set-top boxes, and free ad-supported streaming channels. CTV is the largest part, with the IAB forecasting $29.3 billion of US CTV spending in 2026, up 11%.

How much does digital TV advertising cost?

It depends on the product and the buyer. Self-serve CTV tools have low entry points: Disney Campaign Manager has a minimum of $500 per campaign, Comcast’s Universal Ads advertises no minimum, and Vibe starts at $50 a day. Prices per thousand impressions vary by app, audience and targeting. Addressable linear and premium live sport usually cost more than broad programmatic buys.

How is digital TV advertising measured?

Most national TV deals are still traded on Nielsen audiences, with Comscore, iSpot and VideoAmp certified as alternatives for 2026 to 2028. CTV adds household matching, which links ad exposure to site visits or sales, but the matching is imperfect and many buyers doubt where their ads ran. The most reliable test of results is a geographic holdout comparing regions that saw the campaign with regions that did not.

Is TV advertising better than online video ads?

Neither is better for every goal. TV sets deliver full-screen, sound-on ads that are often watched by several people, and attention scores for linear TV remain higher than for online video, though the gap is narrowing. Online video is cheaper to start, easier to target and quicker to test. Many brands use TV for reach and online video for frequency and response.
