Prvi put reč televizija upotrebljen je [[1900]]. godine, na međunarodnom kongresu u [[Pariz]]u, u delu »Električna televizija« Perskog, a u gotovo isto vreme jedan [[Francuska|francuski]] bibliotekar je grupišući radove koji se odnose na [[elektrika|električno]] prenošenje slike na daljinu upotrebio isti izraz »televizija«. Iako je ovaj izraz u suštini netačan (budući da je televizija prenos i [[slika|slike]] i [[zvuk]]a, dakle prisutan je i element slušanja), opšte je prihvaćen i bilo ga je nemoguće promeniti..<ref>Osnovi organizacije Tv delatnosti, Z.

Television signals were initially distributed only as [[broadcast television]] or [[terrestrial television]] which is modeled on [[radio broadcasting]] systems. Terrestrial television uses high-powered [[Radio frequency|radio-frequency]] transmitters to [[broadcasting|broadcast]] the television signal to individual television receivers. In addition to the original terrestrial transmission method, television signals are also distributed by [[Cable television|co-axial cable or optical fibre]], [[Satellite television|satellite]] systems and over the [[Internet television|Internet]]. Until the early 2000s, television signals were transmitted as [[analog television|analog]] signals but soon countries started switching to [[digital television|digital]] signals, with the [[Digital television transition|transition]] expected to be completed worldwide by late 2010s. A standard television set is composed of multiple internal [[electronic circuit]]s, including circuits for [[Tuner (electronics)|receiving]] and decoding broadcast signals. A visual [[display device]] which lacks a [[tuner (television)|tuner]] is properly called a [[video monitor]] rather than a television.
