What is a FAST channel?

Free ad-supported streaming television

A FAST channel (free ad-supported streaming television) is a linear channel delivered over the internet that viewers watch for free, with advertising in scheduled breaks. It looks and behaves like a television channel but needs no subscription or aerial.

How a FAST channel works

A playout system turns a catalog into a continuous schedule. Markers in the stream signal where ad breaks fall, and an ad system fills each break with ads chosen for that viewer. The channel is then delivered through your own apps, through smart TV channel line-ups or through services that aggregate free channels.

How a FAST channel earns

Revenue is advertising: viewing hours multiplied by ads per hour, fill rate and CPM, divided by 1,000. When a channel is carried by a third-party service, that service usually either shares the ad revenue or takes part of the ad inventory to sell itself.

FAST vs AVOD

Both are free and paid for by ads. In AVOD the viewer picks a title and starts it. In FAST the viewer joins a schedule already in progress. The same catalog can feed both, and many services offer the channel for passive viewing and the on-demand catalog for those who want to choose.

What a FAST channel needs

  • Enough content to fill a schedule without constant repeats, usually a few hundred hours
  • A clear theme: a genre, a single show, a sport, a language
  • Rights that cover free, ad-supported linear distribution
  • A program guide feed for the services that carry the channel
  • Ad demand, direct or programmatic, to fill the breaks

What does FAST stand for?

FAST stands for free ad-supported streaming television.

Is a FAST channel live?

It is delivered as a live stream, but most of what it shows is recorded. The schedule is what makes it linear, not live production.

How much content does a FAST channel need?

There is no fixed minimum. A few hundred hours lets a schedule run without obvious repetition; single-series channels work with less because repetition is the point.
