Television signals were initially distributed isolated as terrestrial television using high-powered radio-frequency transmitters to puff the signal to individual television receivers. Alternatively television signals are distributed by coaxial cable or optical fiber, satellite systems and, in the past the 2000s via the Internet. Until the into the future 2000s, these were transmitted as analog signals, but a transition to digital television is expected to be completed worldwide by the tardy 2010s. A standard television set is composed of fused internal electronic circuits, including a tuner for receiving and decoding announce signals. A visual display device which lacks a tuner is correctly called a video monitor rather than a television.
