In sports broadcasting, a sports commentator provides a real-time live commentary of a game or event, traditionally delivered in the present tense. Radio was the first medium for sports broadcasts, and radio commentators must describe all aspects of the action to listeners who cannot see it for themselves, that way there is an understanding of what is going on. In the case of televised sports coverage, commentators are presented as a voiceover, with images of the contest shown on viewers' screens and sounds of the action and spectators heard in the background. Television commentators are rarely shown on screen during an event, though some networks choose to feature their announcers on camera either before or after the contest or briefly during breaks in the action.
