In sports broadcasting, a commentator gives a running commentary of a game or event in real time, usually during a live broadcast. The comments are normally a voiceover, with the sounds of the action and spectators also heard in the background. In the case of television commentary, the commentator is on screen rarely if at all. In North American English, other general terms for a commentator are announcer, presenter, or sportscaster. (“Sportscaster” may also refer to a newscaster covering sports news.)
