The 1984 season saw a new theme utilized throughout both the pregame show and game-opening sequence, which would be utilized for the remainder of the decade. Another music selection was used for the "Great Moments" segment, a segment of clips from older games on NBC that was unique in that instead of the NFL Films footage, NBC used their own footage and audio.
