A clear definition of FAST channels (free ad-supported streaming TV): how they work, how they make money, and how they differ from OTT, AVOD, and traditional TV.
What Is a FAST Channel? Free Ad-Supported Streaming TV Explained
By Sampath Mallidi, CEO of Revidd · Last updated June 2026
FAST is one of the fastest-growing formats in streaming, but the term gets used loosely. Here is a clear, accurate definition and how it actually works.
A FAST channel (Free Ad-Supported Streaming TV) is a linear, scheduled television channel delivered over the internet, free to viewers, and funded by advertising. It runs a fixed program schedule like traditional TV, plays on connected TV platforms such as Roku, Samsung TV Plus, and Pluto TV, and inserts ads into the stream rather than charging a subscription.
How Does a FAST Channel Work?
A FAST channel works by broadcasting a continuous, pre-scheduled stream of programming that all viewers watch at the same time, exactly like a cable channel, but delivered over the internet. There is no on-demand selection; you tune in to whatever is currently airing, guided by an on-screen program guide.
Behind the scenes, an operator builds a 24-hour schedule from a content library using a playout system, generates an EPG (electronic program guide), and marks ad breaks in the stream using the SCTE-35 standard. The channel is delivered as an HLS stream that connected TV platforms ingest and list in their channel guides.
How Do FAST Channels Make Money?
FAST channels make money from advertising inserted into the stream at marked ad breaks. Because the channel is free to viewers, revenue comes entirely from ads, sold programmatically or directly, and typically shared with the connected TV platform that carries the channel.
The economics improve with a focused, well-defined audience, because advertisers pay more to reach a clear demographic. A themed FAST channel (for example, classic sports, faith programming, or a specific genre) is easier to monetize than an undifferentiated one. This is how operators turn a static library into recurring revenue: Niche Network TV runs 200+ active linear and re-stream channels on Revidd, and a multi-channel FAST operator like TrueVi runs an entire ecosystem of themed channels from one backend.
Most ad insertion on FAST today is server-side. Ads are stitched into the stream by the platform using the SCTE-35 markers the operator sets, so the viewer sees one continuous broadcast with no buffering at the break. For a deeper breakdown of how the ad model works end to end, see our guide on how AVOD works.
How Is FAST Different From OTT, AVOD, and Cable?
FAST is free, linear, and ad-supported, which sets it apart from each of these:
Format | Free? | Linear or on-demand? | Funded by |
|---|---|---|---|
FAST | Yes | Linear (scheduled) | Advertising |
AVOD | Yes | On-demand | Advertising |
SVOD | No | On-demand | Subscription |
Cable TV | No | Linear (scheduled) | Subscription + ads |
FAST is essentially AVOD applied to a linear, scheduled channel. It feels like cable but is free and delivered over the internet. For how to build one, see our guide on how to launch a FAST channel, and for where it fits among revenue models, our SVOD vs AVOD vs TVOD guide.
Why Are FAST Channels Growing?
FAST channels are growing because viewers want free, lean-back TV without another subscription, and because connected TV adoption gives broadcasters a way to reach living-room audiences at scale. The format lets content owners turn an existing library into a 24/7 channel and earn advertising revenue from content that would otherwise sit idle.
The numbers back this up. According to eMarketer, 2026, free ad-supported streaming has moved from a niche format to a core part of how viewers find content on connected TV, with viewership and ad spend both climbing year over year. Statista's FAST outlook projects continued revenue growth for the format through 2027 (Statista, 2025).
What Do You Need to Run a FAST Channel?
To run a FAST channel you need five things: a content library cleared for ad-supported linear distribution, a playout system to assemble the 24/7 schedule, an EPG for the channel guide, SCTE-35 ad markers, and distribution onto connected TV platforms. Each piece has to work together for the channel to air cleanly.
Here is what each component does:
Content library: the programming you schedule. It must be cleared for FAST distribution (the right ad-supported linear rights, not just VOD rights).
Playout and scheduling: the system that turns your library into a continuous 24-hour loop. A drag-and-drop scheduler makes building and changing the lineup fast.
EPG (electronic program guide): the metadata that tells Roku, Samsung, and LG what is airing now and next so the channel shows up correctly in their guides.
SCTE-35 ad insertion: the standard that marks where ads go, so the platform can stitch them in server-side.
Failover: a backup playlist (for example, Revidd's Rescue Playlist) that auto-plays if scheduled content fails or is missing, plus an Ad Filler Playlist that fills an ad break when no ad is available. A FAST channel that goes black, or shows a dead gap at the break, loses both viewers and ad revenue.
Distribution: getting the channel listed on connected TV platforms and inside your own branded apps across Roku, Apple TV, Android TV, Samsung, LG, Vizio, and mobile.
Most broadcasters do not build this stack in-house. A plug-and-play platform supplies the playout, EPG, SCTE-35 insertion, failover, and device apps from one integration, which is how a broadcaster can launch in weeks instead of quarters. Revidd's Program Manager is a drag-and-drop scheduler that fills an hourly timeline from media clips, playlists, and live streams, with Channel Time, UTC, and browser time shown side by side so a schedule built in one timezone does not air an hour off in another.
Scale matters here too. Revidd powers FAST, live, and on-demand across 50+ device endpoints from a single integration and reaches more than 38 million viewers and 5.2 million monthly active viewers across customers in 15 countries. Branded apps can be delivered in as little as one to two weeks, though each platform's own app-store review adds time on top of that and is outside any vendor's control.
Launch Your Own FAST Channel
Now that you know what a FAST channel is and what it takes to run one, the next step is putting it on air. If you have a content library and want to turn it into a free ad-supported channel on connected TV, book a demo and we will show you the scheduling, EPG, and ad insertion that make a broadcast-grade FAST channel.

FAQ
What does FAST stand for?
FAST stands for Free Ad-Supported Streaming TV. It is a linear, scheduled channel delivered over the internet, free to viewers, and funded by advertising.
Is a FAST channel the same as AVOD?
They are related but not the same. AVOD is ad-supported on-demand content viewers choose. FAST is ad-supported linear content on a fixed schedule. FAST is essentially AVOD applied to a scheduled channel.
Where do FAST channels play?
On connected TV platforms and apps such as Roku, Samsung TV Plus, Pluto TV, and LG Channels, and inside broadcasters' own branded apps across mobile and smart TVs.
Do viewers pay for FAST channels?
No. FAST channels are free to viewers. Revenue comes from advertising inserted into the stream, not from subscriptions.
How do I start a FAST channel?
You need a content library cleared for FAST distribution, a playout system to build the schedule and EPG, SCTE-35 ad insertion, and distribution onto connected TV platforms. A plug-and-play platform provides the tooling to do this in weeks.
