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 &amp; white film (kinescope). This therefore, enabled them to reuse the videotape.
