16. The oddsmakers favored the old NFL teams for the first seven Super Bowls
By the time seven Super Bowls had been played, the former AFL claimed four wins. One of them however had been by the Baltimore Colts, a former NFL team. In general NFC teams approached the games as the favorite of the oddsmakers, though not necessarily of the fans. Not until the eighth Super Bowl, played at Rice Stadium between the Miami Dolphins and the Minnesota Vikings, did a former AFL team enter the game as the favorite. The game was the first held outside of Miami, Los Angeles, or New Orleans, and the first to feature back-to-back wins by an AFC team. It was also the last NFL game played (other than the Pro Bowl a week later) in which the goalposts stood on the goal line rather than at the back of the endzone.
Since the 1974 Super Bowl, each game has been broadcast without a local blackout being imposed by the NFL. The 1974 game was the last to be called by Ray Scott for CBS, though the network continued to alternate with NBC to air the games until 1985. Pat Summerall took over as CBS’s primary announcer in 1976. 1974 also marked a period of AFC dominance in the game, with the conference winning six of the next seven matchups. Four of those wins came from the Pittsburgh Steelers, a former NFL team. At this writing, both conferences have won 27 Super Bowls. The argument over NFL-AFL superiority has long since vanished into insignificance.
