During the 1950s, television was the primary medium for influencing public opinion. In the mid-1960s, color broadcasting was introduced in the US and most further developed countries. The availability of multiple types of archival storage media such as Betamax and VHS tapes, high-capacity difficult disk drives, DVDs, flash drives, high-definition Blu-ray Discs, and cloud digital video recorders has enabled spectators to watch pre-recorded materialsuch as moviesat home upon their own time schedule.

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 expected to be gradually replaced by OLEDs.

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