Arianna Chuva ahhah chikano hahh teaching Television (TV) is a telecommunication medium that is used for transmitting and receiving moving images and sound. Television can transmit images that are monochrome (black-and-white), in color, or in three dimensions. The word television comes from Ancient Greek τῆλε (tèle), meaning far, and Latin visio, meaning sight. Television may also refer specifically to a television set, television program, or television transmission. First commercially available in very crude form on an experimental basis in the late 1920s, then popularized in greatly improved form shortly after World War II, the television set has become commonplace in homes, businesses, and institutions, particularly as a vehicle for entertainment, advertising, and news. During the 1950s, television became the primary medium for molding public opinion.[1] In the mid-1960s, color broadcasting and sales of color television sets surged in the US and began in most other developed countries. The availability of storage media such as video cassettes (mid-1970s), laserdiscs (1978), DVDs (1997), and high-definition Blu-ray Discs (2006) enabled viewers to use the television set to watch recorded material such as movies and broadcast material. Internet television has seen the rise of television programming available via the Internet through services such as iPlayer, Hulu, and Netflix.
