Television (TV), sometimes abbreviated to tele or telly, is a telecommunication medium used for transmitting moving images in monochrome (black and white), or in color, and in two or three dimensions and sound. The term can attend to to a television set, a television show, or the medium of television transmission. Television is a growth medium for advertising, entertainment, news, and sports.
Television became available in crude experimental forms in the late 1920s, but it would yet be several years before the supplementary technology would be marketed to consumers. After World engagement II, an enlarged form of black-and-white TV broadcasting became popular in the united Kingdom and united States, and television sets became commonplace in homes, businesses, and institutions. 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 combined 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 listeners to watch pre-recorded materialsuch as moviesat house on their own period schedule. For many reasons, especially the user-friendliness of unapproachable retrieval, the storage of television and video programming now occurs upon the cloud (such as the video on demand promote by Netflix). At the stop of the first decade of the 2000s, digital television transmissions greatly increased in popularity. other move ahead was the impinge on from standard-definition television (SDTV) (576i, in the manner of 576 interlaced lines of total and 480i) to high-definition television (HDTV), which provides a unadulterated that is substantially higher. HDTV may be transmitted in various formats: 1080p, 1080i and 720p. past 2010, in imitation of the invention of intellectual television, Internet television has increased the availability of television programs and movies via the Internet through streaming video facilities such as Netflix, Amazon Video, iPlayer and Hulu.
In 2013, 79% of the world's households owned a television set. The replacement of in front bulky, high-voltage cathode ray tube (CRT) screen displays in imitation of compact, energy-efficient, flat-panel substitute technologies such as LCDs (both fluorescent-backlit and LED), OLED displays, and plasma displays was a hardware chaos that began when computer monitors in the tardy 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 near future, LEDs are usual to be gradually replaced by OLEDs. Also, major manufacturers have announced that they will increasingly fabricate intellectual TVs in the mid-2010s. intellectual TVs behind integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s.
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, in the past the 2000s via the Internet. Until the in advance 2000s, these were transmitted as analog signals, but a transition to digital television is conventional to be completed worldwide by the late 2010s. A standard television set is composed of combined internal electronic circuits, including a tuner for receiving and decoding publicize signals. A visual display device which lacks a tuner is correctly called a video monitor rather than a television.
