Lore & Background
The word television comes from Ancient Greek τῆλε (tele) 'far' and Latin visio 'sight'. Television became available in crude experimental forms in the 1920s. After World War II, improved black-and-white broadcasting became popular in the UK and US. During the 1950s, television was the primary medium for influencing public opinion. In the mid-1960s, color broadcasting was introduced in the U.S. and most other developed countries. The replacement of cathode-ray tube displays with flat-panel technologies such as LCDs, OLEDs, and plasma began with computer monitors in the late 1990s, but most sets sold in the 2000s were still CRT; flat-screen TVs decisively overtook CRT in the early 2010s. Television signals were initially distributed as terrestrial broadcasting using high-powered radio-frequency transmitters. Later, distribution via coaxial cable, optical fiber, satellite systems, and since the 2000s, the Internet became common. Until the early 2000s, signals were analog, but a transition to digital television was expected to be completed worldwide by the late 2010s. A standard television set includes a tuner; a visual display without a tuner is a video monitor.
Reader's Guide
Television's significance lies in its role as a mass medium for advertising, entertainment, news, and sports, capable of more than radio broadcasting. It became the primary medium for influencing public opinion in the 1950s. The development of archival storage media such as Betamax, VHS, LaserDiscs, DVDs, and digital video recorders allowed viewers to watch pre-recorded material at home. By the early 2010s, digital television transmissions greatly increased, and the move from standard-definition to high-definition television provided substantially higher resolution. Since 2010, smart television and Internet television have increased availability of programs via streaming services like Netflix, Amazon Prime Video, iPlayer, and Hulu. The hardware revolution from CRT to flat-panel displays (LCDs, OLEDs, plasma) began in the late 1990s, with flat-screen TVs overtaking CRT by the early 2010s. Major manufacturers discontinued CRT, DLP, plasma, and fluorescent-backlit LCDs by the mid-2010s, and smart TVs became dominant by the late 2010s. Television broadcasts are mainly simplex, meaning the transmitter cannot transmit and the receiver cannot transmit.
