FoxBox (sports)
Fox Box is a term for the digital on-screen graphic used during Fox Sports broadcasts of Major League baseball and the National Football League, among other events. The FoxBox displays real-time information such as the current score in the upper corner of the screen. This graphic remains superimposed over video during live action; it is removed during videotaped replays of field action, during on-camera segments in which the announcers appear, and during commercial breaks or studio cut-ins.
