From the 1966–1976 seasons, NBC Radio alternated with CBS Radio in coverage of the Super Bowl. After sharing coverage of Super Bowl I, NBC Radio would go on to broadcast only odd numbered Super Bowls. Jim Simpson served as the play-by-play man for all of NBC Radio's broadcasts (with the exceptions of Super Bowl III, which was called by Charlie Jones and Super Bowl V, which was called by Jay Randolph) during this era. Simpson, Jones and Randolph were joined on color commentary by George Ratterman (Super Bowls I and III), Pat Summerall (Super Bowl III), Al DeRogatis (Super Bowl V), Kyle Rote (Super Bowl VII), and John Brodie (Super Bowls IX and XI).
