FAST TV (Free Ad-Supported Streaming Television) refers to television channels broadcast via streaming and financed by advertising.

This evokes the classic experience of traditional television, but without the need to use terrestrial signals. This approach is based on the same free-to-air model as AVOD (financed by advertising), but is distinguished by its linear format. Unlike on-demand services, the user does not directly select content to watch, but is instead connected to a continuous stream, similar to the start-up of a conventional television.
