-a ‘tele-communication medium’ used for transmitting ‘moving images’ in ‘monochrome’ (‘black-and-white’), or in ‘color’, and in 2 or 3 ‘dimensions’ and ‘sound’-
.
(it can refer to a ‘television set’, a ‘television program’ (“TV show”), or the medium of ‘television transmission’)
(‘television’ is a ‘mass medium’, for ‘entertainment’, ‘education’, ‘news’, and ‘advertising’)
(‘television’ became available in ‘crude experimental forms’ in the ‘late 1920s’, but these did not sell to the ‘public’)
(after ‘world war II’, an improved form of ‘black-and-white’ TV broadcasting became popular in the ‘united states’ and ‘britain’, 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 ‘storage media’ such as ‘Betamax’ (1975), ‘VHS tape’ (1976), ‘DVDs’ (1997), and high-definition ‘Blu-ray Discs’ (2006) enabled viewers to watch ‘prerecorded material’ at home, such as ‘movies’)
(at the end of the first decade of the 2000s, ‘digital television transmissions’ greatly increased in popularity)
(another development was the move from ‘standard-definition television’ (SDTV) (576i, with 576 interlaced lines of ‘resolution’ and 480i) to ‘high-definition television’ (HDTV), which provides a ‘resolution’ that is substantially higher)
(‘HDTV’ may be transmitted in various formats: ‘1080p’, ‘1080i’, and ‘720p’)
(since 2010, with 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’, ‘iPlayer’, ‘Hulu’, ‘Roku’, and ‘Chromecast’)
(in 2013, 79% of the world’s households owned a ‘television set’)
(the replacement of early bulky, high-voltage ‘cathode ray tube’ (CRT) screen displays with ‘compact’ / ‘energy-efficient’ / ‘flat-panel’ alternative technologies such as ‘plasma displays’, ‘LCDs’ (both fluorescent-backlit and LED), and OLED displays was a hardware revolution that began with ‘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)
(LEDs are expected to be replaced gradually by OLEDs in the near future)
(also, major manufacturers have announced that they will increasingly produce ‘smart TV sets’ in the ‘mid-2010s’)
(‘Smart TVs’ with integrated ‘Internet’ and ‘Web 2.0’ functions became the dominant form of television by the late 2010s)
(‘television signals’ were initially distributed only as ‘terrestrial television’ using ‘high-powered radio-frequency transmitters’ to broadcast the signal to individual television receivers)
(alternatively ‘television signals’ are distributed by ‘coaxial cable’ or ‘optical fiber’, ‘satellite systems’, and, since the 2000s via the ‘internet’)
(until the ‘early 2000s’, these were transmitted as ‘analog signals’ but countries started switching to ‘digital’, this transition is expected to be completed worldwide by ‘late 2010s’)
(a ‘standard television set’ is composed of multiple ‘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’)
