Television signals were initially distributed forlorn as terrestrial television using high-powered radio-frequency transmitters to make known the signal to individual television receivers.

Until the to the front 2000s, these were transmitted as analog signals, but a transition to digital television is standard to be completed worldwide by the late 2010s. A satisfactory television set is composed of combined internal electronic circuits, including a tuner for receiving and decoding make known signals. A visual display device which lacks a tuner is correctly called a video monitor rather than a television.
