What Is FAST TV? Free Ad-Supported Streaming TV, Explained
FAST stands for Free Ad-Supported Streaming TV: linear channels streamed over the internet, free to watch, funded by ads. How it works, who runs it, and why it is growing.

FAST stands for Free Ad-Supported Streaming TV. A FAST channel is a linear TV channel, meaning it follows a fixed schedule you tune into, delivered over the internet instead of cable or antenna. It costs viewers nothing because advertising pays for it.

If you have flipped through live channels on a Roku, a Samsung TV, or Pluto TV, you have watched FAST.
The definition, unpacked
Each word in the acronym carries weight:
- Free. No subscription, no rental fee, usually no account required. This is the sharpest difference from Netflix-style services.
- Ad-Supported. Channels run commercial breaks, typically fewer minutes per hour than cable. Ads are stitched into the stream server-side, so they play like regular TV breaks.
- Streaming. Delivery is over the internet using the same technology (HLS) as any other streaming video. No cable box, satellite dish, or antenna.
- TV. The format is linear television: a schedule, an electronic program guide, and channels you flip between. You watch what is on, like broadcast TV always worked.
FAST vs. cable, antenna, and Netflix
| FAST | Cable TV | Broadcast (antenna) | Netflix-style (SVOD) | |
|---|---|---|---|---|
| Price | Free | $50 to $100+/month | Free | $7 to $25/month |
| Delivery | Internet | Cable line | Over-the-air | Internet |
| Format | Linear channels | Linear channels | Linear channels | On-demand library |
| Ads | Yes | Yes | Yes | Depends on tier |
| Hardware needed | Any smart TV, phone, or browser | Cable box | Antenna | Any smart TV, phone, or browser |

The industry also uses AVOD (Advertising-based Video On Demand) for free on-demand libraries like the core of Tubi or YouTube. The distinction: AVOD is on-demand, FAST is linear. Many services offer both. For a full breakdown, see FAST vs. AVOD vs. SVOD.
Where do you watch FAST channels?
The major FAST services in the US:
- Tubi (Fox): 100 million+ monthly active users as of mid-2025.
- The Roku Channel (Roku): reached 3.0% of all US TV viewing in December 2025 and held that share in January 2026, per Nielsen's The Gauge.
- Pluto TV (Paramount): the original FAST service, launched 2014.
- Samsung TV Plus (Samsung): 100 million+ monthly active users, preinstalled on Samsung TVs.
- LG Channels, Vizio WatchFree+, Xumo Play, Plex, Sling Freestream, and Amazon's Fire TV Channels round out the field.
Smaller platforms, including Vidiyo, host independent and creator-run channels alongside the big aggregators.
How big is FAST?
Three numbers tell the story:
- Pluto TV, The Roku Channel, and Tubi together took 5.7% of all US TV viewing in May 2025, more than any single broadcast network (Nielsen, The Gauge).
- There were roughly 1,850 FAST channels globally as of August 2025, up 76% since 2023 (Gracenote).
- Analysts project global FAST revenue between $11 billion and $31 billion by 2030, depending on how the category is counted.

Why FAST is growing
Viewers are leaving pay TV. Only 36% of US adults still pay for cable or satellite (Pew Research, 2025). Free streaming absorbs much of that viewing time.
Subscription fatigue is real. Two-thirds of US viewers say they would rather save money than avoid ads (Hub Entertainment Research, 2025). Stacking four or five subscriptions costs more than cable did.
Smart TVs ship with FAST built in. Samsung, LG, Vizio, and Roku preinstall their own FAST services on every TV they sell. The distribution is automatic.
Lean-back viewing never died. On-demand means deciding. A linear channel means turning something on and letting it play. A large share of TV time is people who do not want to choose.
How FAST channels work technically
A FAST channel is a playlist on a schedule. The operator uploads a content library, arranges it into a 24/7 program schedule, and the platform generates a continuous HLS stream from it. Ad breaks are marked in the stream (with SCTE-35 markers) and filled at play time through server-side ad insertion, which stitches each viewer's ads directly into their video stream.
The stream is distributed either inside an aggregator app (the channel appears in Pluto TV's or Vidiyo's guide) or as a "branded channel" placement negotiated directly with a platform like Samsung TV Plus.
Who runs FAST channels?
Three groups, increasingly overlapping:
- Media companies spinning existing libraries into channels: a studio's back catalog, a news network's live feed, a genre library.
- Digital-native brands and creators moving from YouTube to the TV screen. TVs are now YouTube's primary viewing device in the US, and creators are following that audience onto linear channels.
- Niche operators programming for a specific interest: horror, fishing, courtroom shows, local news, anime. Linear TV rewards focused channels because viewers know what they will get when they tune in.
