Ray Scott when Scott's broadcast partner, Paul Christman, died on March 2, 1970. Additionally; this would be the last Super Bowl Gifford worked for CBS, as he would leave following the 1970 season to become the play-by-play announcer for Monday Night Football (Gifford would not work another Super Bowl until Super Bowl XIX; the first Super Bowl to air on ABC). CBS erased the videotape a few days after the game; the same thing they did with Super Bowls I and II, which they broadcast. Videotape was expensive then and networks did not believe old games were worth saving. The only reason this game exists is because the CBC and the French version on Radio-Canada in Canada and in Québec carried the broadcast and because the Vikings were located so close to Canada and had a lot of Canadian and Québec fans (and Bud Grant was a legendary player and coach in the CFL), the CBC decided to save it for their archives. As previously mentioned, as videotape was too expensive in those days to save, they transferred the footage to black & white film (kinescope). This therefore, enabled them to reuse the videotape. 44.27 million people in the US watched the game on television, resulting in a rating of 39.4 and a market share of 69. Hank Stram and NFL Films The night before the game, Ed Sabol of NFL Films met with Hank Stram and convinced Stram to wear a hidden microphone during the game so his comments could be recorded for the NFL Films Super Bowl IV film. They agreed the microphone would be kept secret. This would be the first time that a head coach had worn a microphone during a Super Bowl. This has led to one of the best-known and most popular of the NFL Films Super Bowl films due to the constant chatter and wisecracking of Stram. Ed Sabol had his number one sound man, Jack Newman – who also wired Vince Lombardi in a previous playoff game – place the microphone on Stram. Newman, a multiple Emmy award-winning sound man and cameraman, shot Stram for the entire game as well as monitored the sound to make sure it continued to work. The success and popularity of this first Super Bowl wiring of a winning head coach led to 24 years of Newman continuing to wire players and coaches for NFL Films. Some
