The RCA connector is named for the Radio Corporation of America, which first used it in the 1940s to connect phonographs to amplifiers. Generally it refers to a cable with three color-coded plugs, which connect to three correspondingly-colored jacks (these are also called 'phono plugs' and 'phono jacks,' short for phonograph). The colors are usually red and white for right and left audio channels and yellow for composite video.
