Flat-screen televeesions for sale at a consumer electronics store in 2008.

Televeesion (TV) is a telecommunication medium uised for transmittin muivin eemages in monochrome (black an white), or in colour, an in twa or three dimensions an soond. The term can refer tae a televeesion set, a televeesion programme ("TV shaw"), or the medium o televeesion transmission. Televeesion is a mass medium for enterteenment, eddication, news, politics, gossip an advertisin.

Televeesion becam available in crude experimental forms in the late 1920s, but it wad still be several years afore the new technology wis mercatit tae consumers. Efter Warld War II, an impruived form o black-and-white TV braidcastin becam popular in the Unitit States an Breetain, an televeesion sets becam commonplace in hames, businesses, an institutions. In the 1950s, televeesion wis the primar medium for influencin public opeenion.[1] In the mid-1960s, colour braidcastin wus introduced in the US an maist ither developit kintras. The availability o multiple teeps o storage media sic as Betamax, VHS tape, local disks, DVDs, flash drives, heich-defineetion Blu-ray Discs, an deegital video recorders hae enabled viewers tae watch prerecordit material—sic as movies— at hame on thair awn time schedule. For mony raisons, the storage o televeesion an video programmin nou occurs on the clood. At the end o the first decade o the 2000s, deegital televeesion transmissions greatly increased in popularity. Anither development wis the muive frae staundart-defineetion televeesion (SDTV) (576i, wi 576 interlaced lines o resolution an 480i) tae heich-defineetion televeesion (HDTV), that provides a resolution that is substantially heicher. HDTV mey be transmittit in various formats: 1080p, 1080i an 720p. Syne 2010, wi the invention o smairt television, Internet televeesion haes increased the availability o televeesion programmes an movies via the Internet throu streamin video services sic as Netflix, Amazon Video, iPlayer, Hulu, Roku an Chromecast.

In 2013, 79% o the warld's hoosehaulds awned a televeesion set.[2] The replacement o early bouky, heich-voltage cathode ray tube (CRT) screen displays wi compact, energy-efficient, flat-panel alternative technologies sic as plasma displays, LCDs (baith fluorescent-backlit an LED), an OLED displays wis a haurdware revolution that begoud wi computer monitors in the late 1990s. Maist TV sets sauld in the 2000s war flat-panel, mainly LEDs. Major manufacturers annoonced the discontinuation o CRT, DLP, plasma, an even fluorescent-backlit LCDs bi the mid-2010s.[3][4][5] In the near futur, LEDs are expectit tae be gradually replaced bi OLEDs.[6] An aa, major manufacturers hae announced that thay will increasinly produce smairt TVs in the mid-2010s.[7][8][9] Smairt TVs wi integratit Internet an Web 2.0 functions becam the dominant form o televeesion bi the late 2010s.[10]

Televeesion seegnals war ineetially distributit anly as terrestrial televeesion uisin heich-pouered radio-frequency transmitters tae braidcast the seegnal tae individual televeesion receivers. Alternatively televeesion seegnals are distributit bi coaxial cable or optical fiber, satellite seestems an, syne the 2000s via the Internet. Till the early 2000s, thir war transmittit as analog seegnals, but a transeetion tae deegital televeesion is expectit tae be completit warldwide bi the late 2010s. A staundart televeesion set is componed o multiple internal electronic circuits, includin a tuner for receivin an decodin braidcast seegnals. A veesual display device that lacks a tuner is correctly cried a video monitor raither nor a televeesion.
