What Are FAST Channels? How Free Ad-Supported Streaming Works

FAST stands for Free Ad-Supported Streaming TV. It's the category of streaming services that offer free, ad-supported content on connected TV devices like Tubi, Pluto TV, Samsung TV Plus, Peacock Free, Plex, and dozens of others. For viewers, FAST channels look and feel like cable TV: linear channels running scheduled programming, plus on-demand libraries. For publishers, FAST is a distribution and revenue opportunity that didn't exist five years ago.

How FAST Channels Work

FAST platforms operate like traditional TV in one important way: the platform controls the ad experience. Viewers watch for free; the platform inserts ads programmatically and splits revenue with the content provider. Publishers don't manage ad sales or viewer billing; they supply content and collect a share of the ad revenue their programming generates.

Content reaches FAST platforms through structured video feeds, typically MRSS feeds that describe your video library in a format the platform can ingest. When you publish new content, the feed updates and the platform picks it up automatically. The mechanics are similar to syndicating video to a news partner, just on a different delivery surface.

FAST vs. SVOD vs. AVOD

These three acronyms describe different monetization structures in streaming:

  • SVOD (Subscription Video on Demand): viewers pay a monthly fee. Netflix, Disney+, HBO Max.
  • AVOD (Ad-Supported Video on Demand): free, on-demand content with ads. YouTube is the dominant example.
  • FAST: free, ad-supported linear channels on connected TV. Feels like cable, economics like AVOD.

FAST and AVOD are often grouped together because both are ad-funded and free to viewers. The distinction is the linear/on-demand structure and the connected TV context. See our breakdown of OTT monetization models for a fuller comparison.

How Publishers Earn Revenue from FAST

Revenue comes from the platform's advertising sales. When viewers watch your content, the platform serves ads and pays you a share based on the ad impressions your programming generates. The exact split varies by platform and isn't always disclosed publicly, but the structure is consistent: more views, more revenue.

CPMs on FAST platforms tend to be higher than web video because connected TV advertising commands a premium: living room screens, longer viewing sessions, and audience measurement similar to traditional TV. For publishers with quality content and a relevant audience, FAST can outperform web-based AVOD on a per-view basis.

What You Need to Launch a FAST Channel

The barriers to launching a FAST channel are much lower than traditional broadcast, but there are genuine requirements:

  • Content volume: a channel needs enough programming to fill reasonable viewing sessions. Most platforms want at least a few hours of content; more is better for discovery.
  • Rights clearance: you need to own or hold distribution rights for everything in the channel, including background music
  • Technical feed: an MRSS feed that meets the platform's specifications for video format, metadata, and thumbnail requirements
  • Platform application: most FAST platforms have an application or onboarding process, though acceptance criteria vary

The technical setup is where most publishers get slowed down. Each platform has slightly different MRSS requirements, and managing feeds manually across multiple FAST destinations adds real operational overhead.

Distributing to FAST Channels with VideoNest

VideoNest generates and maintains MRSS feeds for your video library automatically. When you upload a new video, every connected FAST destination receives the update without any additional steps. The same library that powers your FAST channels also feeds your CTV apps, podcast directories, and editorial syndication partners — all from one upload.

For publishers with existing content libraries who want to reach FAST platforms, the process is: import your library, configure the feed, apply to the platforms you want to reach. VideoNest handles the feed maintenance, format compliance, and automatic updates as you publish new content.
