AVOD vs. SVOD vs. TVOD: What each model means for advertisers
TL;DR: What to know about AVOD, SVOD, TVOD, and FAST
- Ad-supported streaming is growing as viewers move away from traditional TV and increasingly choose lower-cost streaming options with ads.
- Streaming models differ in how viewers access content and how advertisers can reach them. AVOD and FAST are ad-supported, while TVOD is ad-free.
- Advertisers can buy streaming inventory through direct IOs, programmatic guaranteed deals, PMPs, and open auctions.
- Platforms like StackAdapt help advertisers manage AVOD and FAST inventory across publishers, making it easier to expand reach.
Nearly half of all TV advertising now happens on streaming platforms. In the first quarter of 2026, 73% of total TV viewing in the US was ad-supported, with streaming accounting for 46.6% of that ad-supported viewing. And by 2027, connected TV (CTV) will represent 49.7% of TV advertising.
But it can be difficult for advertisers to understand and take advantage of the opportunities ad-supported streaming presents. With acronyms like AVOD, SVOD, TVOD, and FAST being thrown around loosely and CTV inventory varying widely in availability, advertisers are often unsure about what they can actually buy when it comes to streaming.
If you’re wondering what the differences are between AVOD, SVOD, TVOD, and FAST, read on to learn which models carry ad inventory and how to access it.
What is VOD?
Video on demand (VOD) is an over-the-top (OTT) content delivery method that allows the viewer to choose when they watch something, as opposed to tuning into a scheduled program. That user-initiated delivery stands in contrast to linear channels like traditional cable broadcasts, which offer scheduled delivery.
OTT includes content delivered over the internet—rather than via broadcast television, cable networks, or satellites—and watched on devices like computers or smart TVs. CTV is a subset of OTT.
In 2026, streaming hit a record high of 48.6% of total TV watch-time. The rise in streaming has lowered traditional linear TV consumption, which has led to new opportunities for advertisers. In fact, EMARKETER reports that CTV ad spend is expected to surpass linear TV for the first time by 2028.
CTV advertising specifically targets viewers using a CTV device. Because CTV content is often viewed on larger screens in a more relaxed environment, CTV ads are typically known for having higher ad recall and tolerance.
But the way viewers access CTV content isn’t all the same.
There are multiple business layers within VOD, primarily subscription video on demand (SVOD), advertising-based video on demand (AVOD), and transactional video on demand (TVOD). The first letter in each abbreviation indicates how the content is funded or accessed—whether through a subscription, advertising, or individual transaction—and each model offers advertisers different opportunities and audiences to reach.
Let’s break down the details of each.
What is SVOD?
With SVOD, viewers pay a recurring fee for unlimited access to a content library. Popular SVOD streamers include Netflix, Disney+, Amazon Prime Video, HBO Max, Paramount+, Hulu, and Peacock.
SVOD platforms are practically ubiquitous, with 90% of US households paying for at least one SVOD service and subscribing to four services on average.
Known for their exclusive premium content, these streaming platforms traditionally generated revenue solely through subscription fees, which meant they were largely closed to advertisers. But in the last couple of years, many platforms have introduced more affordable ad-supported tiers that cost less for viewers to stream content, opening the door to advertisers.
What is AVOD?
AVOD delivers content that is free—or available at a significantly lower cost—to consumers in exchange for watching ads. With the growth of ad-supported tiers on SVOD platforms, AVOD and SVOD are no longer separate services, but the same services sold two different ways.
Common AVOD providers include The Roku Channel, Tubi, and Pluto TV, as well as the aforementioned ad-supported tiers of streamers like Netflix, Disney+, and Amazon Prime Video.
Ad-supported tiers give advertisers access to highly engaged audiences and premium inventory, which typically comes with higher CPMs (but more precision than traditional TV advertising).
Inventory can be sold either through direct sales and upfronts, which may involve significant spending commitments, or programmatically through demand-side platforms like StackAdapt. Programmatic options can include fixed-price guaranteed buys or biddable auctions on the open internet or private marketplaces.
Due to the low cost of access, the AVOD audience is broad and wide-reaching. In fact, audiences spend more time with ad-supported TV than with ad-free TV. Nielsen recently reported that adults ages 18 to 49 spend 63.8% of their TV time with ad-supported TV, highlighting the value exchange viewers are willing to make to access the content they want to watch.
In the AVOD model, advertising revenue helps platforms fund content and operations while giving brands access to viewers through high-impact ad placements. Because advertisers cover the cost of access, they serve as the primary revenue engine. This dynamic transforms viewers from paying customers into engaged audiences—giving advertisers access to a broad pool of viewers across premium streaming environments.
For advertisers, the inventory environment combines the scale of traditional television with the targeting capabilities of digital media. AVOD platforms also maintain lighter ad loads, typically capping commercial time at four to eight minutes per hour—providing better brand recall and stronger return on ad spend without inducing ad fatigue. When campaigns are managed through platforms like StackAdapt, which support frequency capping and brand safety controls, advertisers can also reduce repetitive exposure, keeping placements aligned with appropriate content.
What is FAST?
Like AVOD, FAST provides ad-supported content to viewers. But the main distinction between FAST and AVOD comes down to how content is delivered, not funding.
Both models rely on advertising revenue to provide content at reduced or no cost to viewers, but FAST delivers content continuously according to a programmed schedule with limited on-demand streaming options. In contrast, AVOD is entirely on demand, allowing viewers to select what they want to watch whenever they want.
From a media buying perspective, this delivery difference can influence how brands plan, target, and value inventory across both environments.
What is the content mix of AVOD vs. FAST?
FAST content tends to rely heavily on a library of older content, niche thematic channels, news programming, and, increasingly, sports coverage. It continues to rapidly scale, with the number of FAST channels growing 17.5% year-over-year (YoY) to 2,172 channels globally in 2026.
Premium AVOD, on the other hand, provides access to an array of on-demand programming, including current-season releases, high-budget original series, and blockbuster films.
How does targeting differ between AVOD vs. FAST?
With AVOD, depending on the platform being used and available data, advertisers may be able to use audience, behavioral, demographic, and first-party data for targeting.
FAST linear feeds, meanwhile, function more like traditional linear TV, with viewers frequently tuning into scheduled programming on dedicated channels rather than selecting individual titles. Advertisers can still use audience, contextual, geographic, and other targeting tactics, but the content context may be limited.
How does viewing behavior differ between AVOD vs. FAST?
FAST lends itself to more passive, lean-back viewing, where viewers can tune into curated channels.
AVOD caters to intentional, lean-forward viewing where the audience chooses a specific title to watch.
What is the ad load of AVOD vs. FAST?
The viewer experience between AVOD and FAST can also differ in ad volume. Traditional cable programming carries heavy commercial loads averaging 15 to 18 minutes per hour. Premium AVOD platforms keep ad loads low, averaging around four to eight minutes of ads per hour. FAST sits squarely in the middle, running approximately eight to 12 minutes of ads per hour—lighter than legacy cable, but denser than many premium AVOD services.
How does the pricing and value of advertising differ between AVOD vs. FAST?
Premium AVOD ad inventory typically commands higher rates than FAST inventory based on factors such as the platform, audience, content, and buying method. When deciding what to buy, advertisers need to weigh the inventory and audiences available against their campaign goals.
What is TVOD?
TVOD refers to transactional video on demand.
Think of TVOD as the digital evolution of the traditional video rental store.
Under this model, viewers pay for individual pieces of content on a title-by-title basis—either as a short-term rental or a permanent digital purchase—rather than paying a recurring monthly subscription fee.
Platforms like Apple TV, Amazon Prime Video Store, and Google TV are examples of TVOD environments. A high-margin extension of this model is premium video on demand (PVOD), which allows consumers to rent or purchase major feature films while they’re still in theaters or within an exclusive early-access home-viewing window, typically at a higher price point.
For advertisers, TVOD carries essentially no ad inventory. Because consumers pay directly for the content, TVOD viewing is ad-free.
For media planning purposes, TVOD should be used to provide market context rather than as an actionable ad channel.
That said, recent market data suggests consumers are increasingly pulling back on direct digital purchases in favor of bundled or ad-supported streaming options.
According to a 2026 report from DEG, US consumer spending on digital purchases fell 18.7% YoY to $521 million USD, while VOD rental spending dropped 6.6% to $443 million USD. As transactional spending softens, audiences are increasingly funneling toward ad-supported tiers—expanding the reachable audience pool for advertisers.
AVOD vs. SVOD vs. TVOD: What are the key differences?
For media buyers and strategists, there’s no single “best” platform revenue model. The real strategic questions are which models offer ad inventory and how they can help you achieve your campaign goals.
While consumers navigate streaming based on subscription costs and content availability, marketers must assess how each model shapes targeting, pricing, and reach.
Here’s a quick comparison of SVOD, AVOD, and TVOD:
| AVOD | SVOD | TVOD | FAST | |
| Cost to viewer | Free or lower cost to the end consumer | Paid recurring fee (ad-free tiers pay full price) | Pay-per-title via a single transaction (rental fee or permanent purchase) | Free to the viewer |
| How platforms make money | Exclusively via advertiser spend (CPM impressions and sponsorships) | Primary recurring subscription fees | Direct consumer purchase/rental fees | Primarily through advertiser spend |
| Ad inventory availability | 100% ad-supported: Broad inventory across all titles and sessions | Hybrid availability: Ad inventory is only available to viewers with discounted, ad-supported subscriptions | None: TVOD is typically ad-free | 100% ad-supported: Inventory across scheduled streaming channels |
| Audience reach & scale | Massive, top-of-funnel reach with low barriers to entry | Deep, highly engaged reach gated by subscriber login and paywalls | Niche, fragmented reach for specific blockbuster releases or marquee live events | Broad, efficient incremental reach, particularly among cord-cutters and viewers who favor free content |
| Content mix | Deep library content, unscripted TV, news, syndicated series, and curated channels | Current-season originals, tentpole series, premium movies, and exclusive sports events | New theatrical releases, early-window films (PVOD), and pay-per-view (PPV) events | Older library content, niche thematic channels, news programming, and increasingly sports |
| Example platforms | Disney+, Hulu, Paramount+ | Netflix, Amazon Prime Video, HBO Max | Apple TV, Prime Video Store, Google TV | Pluto TV, Tubi, The Roku Channel |
Why is ad-supported streaming inventory growing?
CTV ad spend is accelerating, with supply expansion being driven by subscription churn, price sensitivity, and linear cord-cutting.
The growth of ad-supported streaming inventory is the direct outcome of consumers actively reallocating their entertainment budgets, which has created the vast AVOD and hybrid supply that advertisers are buying today.
With increasing costs and a seemingly endless selection of streaming platforms available, consumers are no longer treating SVOD as a fixed monthly cost. Instead, subscription fatigue has created a dynamic cycle of tier-shifting and platform swapping that’s seeing households move from ad-free tiers to less expensive ad-supported ones across major platforms like Netflix and Disney+.
Case in point: A 2026 study from Deloitte found that 41% of consumers canceled an SVOD service within a six-month window, but 22% of those who ultimately churned ended up returning to the same service, opting for a cheaper, ad-supported tier to keep household entertainment costs in check.
Furthermore, the steady decline of legacy cable and satellite TV has channeled a consistent influx of viewers into ad-supported streaming environments. And when consumers cut the cord, they tend to replace linear channels with ad-supported alternatives.
According to Antenna, 31% of cord-cutters sign up for a new streaming service within a month of canceling pay TV—a sign-up rate roughly five times higher than the general population. And while 72% of traditional cord-cutters already hold at least one premium SVOD subscription prior to canceling, they overwhelmingly expand their streaming with free ad-supported platforms or take on discounted ad-supported tiers to replace linear channels.
As cord-cutting accelerates and consumers further lean on discounted ad-supported tiers for their entertainment, the total pool of ad-supported CTV impressions increases—giving advertisers even more reach across streaming.
How do you advertise on AVOD and ad-supported streaming?
Navigating ad-supported streaming requires understanding both the ways inventory is purchased and how campaigns are managed.
Unlike traditional linear television, where inventory is primarily locked into upfront commitments, CTV inventory is accessible through several direct and automated routes—each with trade-offs when it comes to access, control, and overall cost.
When buying ad-supported streaming inventory, there are four primary methods:
1. Direct insertion orders (IOs)
Buying directly from a publisher’s internal ad sales team can provide access to premium inventory, custom sponsorships, live sports, and high-quality placements. IOs can also be executed through StackAdapt, but because they’re done off platform, targeting is more limited and reporting isn’t centralized in one place.
That said, direct IOs can sometimes require high minimum spend commitments per publisher and limit execution to a single network’s ecosystem, which can fragment campaign management across a broader media plan.
2. Programmatic guaranteed deals
Programmatic guaranteed combines the exclusivity of a direct IO with the flexibility and automation of programmatic advertising. The buyer and publisher agree on a fixed CPM and reserved volume upfront, and the reserved inventory is then delivered through an automated workflow. This ensures guaranteed placement in top-tier content, while making campaigns easier to manage.
3. Private marketplace (PMP) deals
Private marketplaces are invite-only, unreserved auctions where publishers offer curated packages of inventory—such as live events like the FIFA World Cup—to a select group of buyers at an agreed-upon floor price. PMPs offer a balance of premium publisher access, contextual control, and buying flexibility without the rigid upfront spend commitments commonly associated with traditional buying methods.
4. Open auctions
The open marketplace offers the widest reach and most affordable pricing by combining unreserved inventory across the broader streaming ecosystem. While it provides maximum flexibility and immediate scale, it offers less publisher-level control than direct IOs or PMPs, depending on the inventory source and deal structure.
Activating cross-publisher campaigns
Executing streaming buys through single-publisher channels creates operational silos that limit audience reach and hinder the ability to holistically measure performance.
To achieve scale without sacrificing efficiency, media buyers should use an AI-powered programmatic platform like StackAdapt, which allows advertisers to access premium inventory, target audiences across multiple publishers, and measure results from a single platform.
Managing frequency across duplicated reach
The average consumer maintains active accounts across multiple ad-supported services. For example, they might watch a prestige drama on a premium ad-supported streaming service before switching to a FAST channel for more easy-going viewing. As a result, the exact same user is often reachable across multiple environments simultaneously.
This cross-platform usage can inadvertently duplicate reach. When buyers execute separate campaigns directly with individual publishers, each platform operates in a vacuum. A viewer might be capped at three impressions on one service, three on another, and three on a third—resulting in a single consumer seeing the exact same commercial nine times in one evening.
In CTV advertising, frequency management is a planning problem, not a post-campaign reporting metric. If frequency is evaluated only after a campaign ends, budget waste and ad fatigue have likely already occurred.
Controlling cross-publisher frequency requires buying inventory from a single centralized hub. By managing programmatic ad buys through a platform like StackAdapt, advertisers gain real-time, household-level visibility across all connected supply sources. The platform dynamically adjusts bidding behavior based on historical impression delivery across publishers, ensuring that once a household reaches its limit on one service, ad delivery automatically shifts to unexposed audiences elsewhere.
This centralized control eliminates wasted ad spend, prevents ad fatigue, and ensures every dollar invested in streaming inventory drives true incremental reach.
How do AVOD and FAST work together in one media plan?
Because the vast majority of AVOD and FAST viewing occurs on television sets, both models represent inventory sources within a broader CTV campaign. The strategic decision isn’t choosing between AVOD or FAST, but determining how these different inventory types can balance reach, cost, and content quality across a media plan to achieve your campaign goals.
Premium AVOD tiers are best suited for high-attention placements and deeper deterministic audience targeting based on subscriber accounts.
FAST channels are ideal for expanding efficient incremental reach, capturing cord-cutters in passive, lean-back viewing environments, and engaging audience segments that favor free content over paid subscriptions.
Combining AVOD and FAST in the same media plan might look something like using AVOD inventory to reach priority audiences around high-value or current content (for example, premium programming and live sports), then layering in FAST inventory to expand incremental reach to viewers outside of premium subscription environments, all while managing both together to avoid overexposure within the same households.
Making the most of ad-supported streaming
Effective CTV planning doesn’t require choosing one model over another. The most successful CTV campaigns combine multiple streaming models—adjusting the ratio of AVOD, FAST, and live streaming inventory to deliver maximum impact across every screen.
