Super Bowl V. Schachter, one of six men to serve as referee for at least three Super Bowls, worked as an officiating supervisor and instant replay official following his on-field retirement. This was the first Super Bowl where penalties and other information were announced by the referee over a wireless microphone, an innovation of Cowboys general manager Tex Schramm which went into effect at the start of the 1975 season.
