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 other developed countries. The availability of compound 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 viewers to watch pre-recorded materialsuch as moviesat house upon their own grow old schedule. For many reasons, especially the user-friendliness of detached retrieval, the storage of television and video programming now occurs on the cloud (such as the video on demand sustain by Netflix). At the stop of the first decade of the 2000s, digital television transmissions greatly increased in popularity. complementary move on was the have an effect on from standard-definition television (SDTV) (576i, like 576 interlaced lines of unadulterated and 480i) to high-definition television (HDTV), which provides a pure that is substantially higher. HDTV may be transmitted in various formats: 1080p, 1080i and 720p. previously 2010, in the same way as the invention of smart television, Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Video, iPlayer and Hulu.
In 2013, 79% of the world's households owned a television set. The replacement of into the future bulky, high-voltage cathode ray tube (CRT) screen displays afterward compact, energy-efficient, flat-panel every other technologies such as LCDs (both fluorescent-backlit and LED), OLED displays, and plasma displays was a hardware lawlessness that began similar to computer monitors in the late 1990s. 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 close future, LEDs are traditional to be gradually replaced by OLEDs.

Television signals were initially distributed lonesome as terrestrial television using high-powered radio-frequency transmitters to shout from the rooftops 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 to the front 2000s, these were transmitted as analog signals, but a transition to digital television is time-honored to be completed worldwide by the tardy 2010s. A all right television set is composed of complex internal electronic circuits, including a tuner for receiving and decoding shout from the rooftops signals.
