The evolution of Television

The Television is a telecommunication medium used for transmitting moving images in monochrome (black and white), or in colour, and in two or three dimensions and sound. Television is a mass medium for advertising, entertainment and news.

Television became available in crude experimental forms in the late 1920s. During the 1950s, television was the primary medium for influencing public opinion. In the mid-1960s, color broadcasting was introduced in most developed countries.

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, Amazon Video, iPlayer and Hulu. The replacement of early bulky, high-voltage cathode ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs (both fluorescent-backlit and LED), OLED displays, and plasma 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. In the near future, LEDs are expected to be gradually replaced by OLEDs. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s.

Television signals are distributed by coaxial cable or optical fiber, satellite systems and, since the 2000s via the Internet. 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.
