Linear TV, also known as traditional television or broadcast television, refers to the format in which television programs are broadcast over the air or via cable or satellite, and are watched by viewers at the same time as they are broadcast. Linear TV is characterized by its fixed schedule, which is determined by the television network or broadcaster, and its one-to-many model, in which a single program is broadcast to all viewers at the same time. Linear TV is the dominant form of television, and is still widely used by broadcasters to reach large audiences with their programming. However, it is facing increasing competition from non-linear forms of television, such as streaming video, which allow viewers to access content on demand and on their own schedule.
