FAST vs. AVOD comes down to one thing: who decides what plays next. FAST, which stands for free ad-supported streaming television, gives you linear channels on a set schedule, the way cable does. AVOD, or ad-supported video on demand, gives you a library to browse and pick from, the way Netflix does. Both are genuinely free, both are paid for by commercials, and most of the big free apps now offer both under the same roof.
How FAST Works
A FAST channel runs on a fixed schedule set by the distributor. You open a channel guide, pick one, and land in the middle of whatever’s currently airing. No pause, no rewind, no choosing the next episode. Industry people call it a “lean-back” experience because it removes the decision fatigue of scrolling through thousands of titles.
Channels are usually themed. One might run classic westerns all day, another 90s sitcoms, another live news. The programming leans on older movies, completed TV series, reality shows, documentaries, and niche sports. Reality has been the fastest-growing category, and sports-focused channels have more than doubled in the past year.
The scale is real. More than 1,300 FAST channels are available in the United States, roughly 45 percent of U.S. internet households now watch FAST services, and total viewing hours jumped 43 percent between August 2024 and August 2025, reaching 1.8 billion hours. The biggest FAST distributors each claim more than 50 million viewers.
How AVOD Works
AVOD flips the model. You open an app, browse or search a catalog, and start whatever you want on your own schedule. Pause it, rewind, stop halfway through, come back next week. The experience is identical to a paid streaming service except for the commercial breaks.
Catalogs are organized by genre, popularity, release date, and recommendations based on your viewing history. AVOD platforms compete on the depth and freshness of their libraries, so they license newer titles more aggressively than FAST channels do and occasionally produce originals. If you know what you want to watch, this is the model built for you.
Ads on AVOD are targeted using your viewing behavior and demographic profile, which makes each impression more valuable to advertisers. That’s part of why AVOD platforms can afford newer content while still charging viewers nothing.
The Differences That Matter to a Viewer
Three things separate the two experiences in practice.
Control. FAST decides what’s on; you decide whether to watch. AVOD lets you pick the title, the episode, and the moment you start. If you want to zone out, FAST works better. If you want a specific movie or want to binge a full season, AVOD is the obvious choice.
Content mix. FAST leans heavily on library titles because older content licenses cheaply and fills a 24/7 themed channel efficiently. Live news and niche sports are growing on FAST, but the marquee live events still go to paid services. AVOD generally carries a wider and more current selection, with some platforms licensing content within months of its original run.
Ad load. FAST channels typically run about 8 to 10 minutes of ads per hour. That’s less than cable’s 10 to 16, but still a steady presence, and the breaks land at fixed intervals you can’t skip. AVOD tends to be lighter, roughly 4 to 8 minutes per hour, usually a pre-roll ad and then mid-roll breaks placed at natural scene transitions. Neither model lets you skip commercials. That’s the trade for free access.
Where to Find Each
The largest FAST services include Pluto TV, Samsung TV Plus, The Roku Channel, and the linear side of Tubi. Samsung TV Plus is built into Samsung smart TVs made since 2016 and requires no account, no signup, and no payment information. You turn on the TV and the channels are there.
Major AVOD platforms include Tubi’s on-demand library, the free tiers of Peacock and Crackle, and YouTube’s ad-supported catalog. Tubi runs a pure AVOD model for its main library, paying content owners through licensing or revenue-sharing deals. YouTube works differently: creators upload directly and split ad revenue with the platform rather than licensing titles.
The line between the two has blurred. Pluto TV, Tubi, and The Roku Channel all offer both linear channels and on-demand libraries in the same app. Surf channels when you feel like zoning out, then switch to on-demand when you know what you want. Treating FAST and AVOD as two modes inside the same free ecosystem is more useful than treating them as competing services.
Getting started takes almost nothing. Unlike paid services that require a credit card before you see any content, most FAST apps let you start watching immediately. Pluto TV and Tubi offer optional accounts that unlock favorites and watch history, but signing up isn’t required.
Paid Ad Tiers Are Not the Same Thing
The growth of free ad-supported viewing pushed traditional subscription services to launch cheaper ad-supported plans, and those get confused with FAST and AVOD. They shouldn’t be. Netflix’s ad tier costs about $8 per month, Disney+ with ads runs around $13 when bundled with Hulu, HBO Max’s ad plan is about $11, and Peacock’s ad-supported tier is roughly $11. Amazon’s base Prime Video now includes ads by default, with an ad-free upgrade recently raised to $4.99 per month on top of Prime membership.1CNBC. Amazon to Hike Price of Ad-Free Prime Video Tier
A viewer watching Peacock’s free tier is using AVOD. A viewer paying $10.99 per month for Peacock Premium with ads is using a paid ad-supported tier. Both have commercials, but one costs money and typically offers a larger library and fewer interruptions. FAST and AVOD are the ones that cost nothing.
What You Give Up for Free
Free streaming has a cost, and the cost is your viewing data. Both FAST and AVOD platforms collect information about what you watch, when you watch, and how you interact with ads. AVOD tends to collect more because on-demand behavior produces richer signals: every search, every title you hover over, every show you abandon at the ten-minute mark feeds a profile used to target ads and recommend content.
An FTC staff report found that major video streaming and social media companies have engaged in what the agency called vast surveillance of users, with data collection practices the report described as “woefully inadequate” for protecting privacy, and noted that users often have little or no way to opt out of how their information is used by algorithms and automated systems.2Federal Trade Commission. FTC Staff Report Finds Large Social Media and Video Streaming Companies Have Engaged in Vast Surveillance of Users with Lax Privacy Controls and Inadequate Safeguards for Kids and Teens The FTC has recommended comprehensive federal privacy legislation, but as of 2026 no such law has passed.
Households with children have more to think about. The Children’s Online Privacy Protection Act restricts how platforms can collect data from kids under 13, with penalties reaching $53,088 per violation. Most free streaming services include parental controls or kid-friendly sections, but you have to turn them on.
Advertising truthfulness standards apply to these digital placements the same way they apply elsewhere. Claims in ads must be truthful and evidence-based, and platforms can face enforcement action for running deceptive advertising.3Federal Trade Commission. Advertising and Marketing
Which One Should You Use
Pick FAST when you want the TV to make the decisions. It’s better for background viewing, sports and news you want to drop into, and the comfort of a themed channel that just keeps going. Pick AVOD when you have a title in mind, want to binge a series, or care about a bigger and more current library. Since Pluto TV, Tubi, and The Roku Channel all deliver both, the practical answer for most viewers is to install one of those apps and switch modes depending on what you feel like doing.
