What Is Linear TV? Definition, and Why It Outlived Cable
What is linear TV? Linear TV is scheduled programming on channels you tune into. Learn how it differs from on demand and why FAST channels made linear grow.
Linear TV is television programmed on a fixed schedule: shows air on a channel at set times, and everyone watching that channel sees the same thing at the same moment. You tune in, and something is already playing. Broadcast networks, cable channels, and modern FAST streaming channels are all linear. The opposite model is on demand, where each viewer picks a title and starts it whenever they want.
The word "linear" describes the viewing path: one program follows another along a timeline the programmer chose. The model predates the internet by decades, yet it did not die with cable. It moved online, and free streaming channels are now one of the fastest-growing corners of TV. This guide explains the format, the contrast with on demand, and why linear survived.
Linear vs on demand: what's the difference?
The split comes down to who controls the clock. In linear TV, the programmer does. In on-demand viewing, the viewer does.
| Linear TV | On demand | |
|---|---|---|
| Start time | Fixed by a schedule | Chosen by the viewer |
| What everyone sees | The same program at the same time | Each viewer watches something different |
| Effort required | None: tune in and watch | Browse, evaluate, choose, press play |
| Navigation | Channel numbers and a program guide | Menus, rows, and search |
| Examples | NBC, ESPN, a 24/7 FAST channel | Netflix library, YouTube, Tubi's catalog |
Neither model is winning outright; they serve different moods. On demand rewards intent: you know what you want. Linear rewards the absence of intent: you want TV to just happen. Both now live inside the same streaming apps, which is why the distinction matters more than ever.
Why did linear TV survive the streaming era?
Cable subscriptions collapsed. Only 36 percent of US adults still pay for cable or satellite, and just 16 percent of adults under 30 do (Pew Research, 2025). Yet the linear format itself kept growing, for three durable reasons.
Choice fatigue is real. Endless catalogs turn picking a show into work. A linear channel removes the decision: it is already playing, and you either stay or flip. That lean-back quality is the format's core product.
Linear is how discovery happens. An on-demand menu shows you posters; a channel shows you the actual content. Viewers sample things they would never have clicked on, which is valuable to programmers and audiences alike.
Shared schedules create shared moments. Live sports, news, and event programming only work linearly. Everyone sees it together, which no on-demand queue can replicate.
FAST channels: linear TV, rebuilt on the internet
FAST (free ad-supported streaming TV) is the linear format delivered over the internet instead of cable. Channels run 24/7 schedules, appear in a program guide, and cost nothing to watch; ads fund them. The scale is no longer niche. Gracenote counted roughly 1,850 FAST channels globally in August 2025, up 76 percent since 2023, carrying about 197,000 unique programs.
Audience behavior followed. Pluto TV, The Roku Channel, and Tubi together took 5.7 percent of all US TV viewing in May 2025, more than any single broadcast network (Nielsen). Streaming overall hit a record 47.5 percent of US TV viewing in December 2025 (Nielsen, The Gauge). Every figure here, with sources, sits in the FAST industry statistics hub.
The biggest change is who can program a channel. Cable linear required carriage deals and transmission infrastructure. Internet linear requires software. On Vidiyo, anyone can run a 24/7 linear channel free: upload videos, arrange the schedule, and the platform handles transcoding, playout, ad insertion, and the program guide. The craft of filling a round-the-clock schedule is its own discipline; start with 24/7 channel scheduling and playout.
Is linear TV the same as live TV?
No, and the difference trips people up. Live TV means the content is happening now: a game, a newscast, a live stream. Linear TV means the content follows a schedule, whether it is live or pre-recorded. A sitcom rerun airing at 9 PM is linear but not live. A live game is both. Most FAST channel programming is scheduled pre-recorded content, so it is linear without being live. The FAST TV glossary covers these terms and the rest of the vocabulary.
Quick answers
What does linear mean in TV? It means programming that airs on a fixed schedule, one show after another on a channel. Viewers tune in to whatever is playing rather than picking a title.
Is linear TV dying? Cable and broadcast distribution is shrinking, but the linear format is growing on the internet. Free streaming channels brought scheduled TV to streaming apps, and their viewing keeps rising.
Is Netflix linear TV? The core Netflix library is on demand, not linear. Some streamers now add scheduled channel-style feeds, which are linear features inside an on-demand service.
Can anyone start a linear channel now? Yes. Platforms like Vidiyo let you upload a video library, build a 24/7 schedule, and stream it as a free ad-supported channel; see how to start a FAST channel.
