Television is a telecommunication medium for transmitting and receiving moving images that can be monochrome or colored, with or without accompanying sound. "Television" may also refer specifically to a television set, television programming, or television transmission. The etymology of the word has a mixed Latin and Greek origin, meaning "far sight": Greek tele, far, and Latin visio, sight. Commercially available since the late 1920s, the television set has become commonplace in homes, businesses and institutions, particularly as a vehicle for advertising, a source of entertainment, and news. Since the 1950s, television has been the main medium for molding public opinion. Since the 1970s the availability of video cassettes, laserdiscs, DVDs and now Blu-ray Discs, have resulted in the television set frequently being used for viewing recorded as well as broadcast material. In recent years, Internet television has seen the rise of television available via the Internet through services such as iPlayer and Hulu. Although other forms such as closed-circuit television are in use, the most common usage of the medium is for broadcast television, which was modeled on the existing radio broadcasting systems developed in the 1920s, and uses high-powered radio-frequency transmitters to broadcast the television signal to individual TV receivers. LESS
