Most TV sets sold in the 2000s were flat-panel, mainly LEDs. Major manufacturers announced the discontinuation of CRT, DLP, plasma, and even fluorescent-backlit LCDs by the mid-2010s. In the near future, LEDs are conventional to be gradually replaced by OLEDs.

Television signals were initially distributed solitary as terrestrial television using high-powered radio-frequency transmitters to make public 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 before 2000s, these were transmitted as analog signals, but a transition to digital television is standard to be completed worldwide by the late 2010s. A good enough television set is composed of fused internal electronic circuits, including a tuner for receiving and decoding shout from the rooftops signals. A visual display device which lacks a tuner is correctly called a video monitor rather than a television.
