The first AFL–NFL World Championship Game (known retroactively as Super BowlI and referred to in contemporaneous reports, including the game's radio broadcast, as the Super Bowl) was an American football game played on January 15, 1967, at the Los Angeles Memorial Coliseum in Los Angeles, California. The National Football League (NFL) champion Green Bay Packers defeated the American Football League (AFL) champion Kansas City Chiefs by the score of 35–10. Coming into the game, considerable animosity existed between the AFL and NFL, thus the teams representing the two rival leagues (Kansas City and Green Bay, respectively) felt additional pressure to win. The Chiefs posted an 11–2–1 record during the regular season, and defeated the Buffalo Bills 31–7 in the AFL Championship Game. The Packers finished the regular season at 12–2 and defeated the Dallas Cowboys 34–27 in the NFL Championship Game. Many sportswriters and fans believed any team in the older NFL was vastly superior to any club in the upstart AFL, and so expected Green Bay would blow out Kansas City. The first half of Super Bowl I was competitive, as the Chiefs outgained the Packers in total yards, and kept pace with Green Bay by posting a score at halftime. Early in the third quarter, Green Bay safety Willie Wood intercepted a pass and returned it 50 yards to the 5-yard line. The turnover sparked the Packers to score 21 unanswered points in the second half. Green Bay quarterback Bart Starr, who completed 16 of 23 passes for 250 yards and two touchdowns, with one interception, was named MVP. The game remains the only Super Bowl to have been simulcast in the United States by two networks. NBC had the rights to nationally televise AFL games, while CBS held the rights to broadcast NFL games; both were allowed to televise the game. Background Origins When the NFL began its 41st season in , it had a new and unwanted rival: the American Football League. The NFL had successfully fended off several other rival leagues in the past, and so the older league initially ignored the new upstart and its eight teams, figuring it would be made up of nothing but NFL rejects, and that fans were unlikely to prefer it to the NFL. But unlike the NFL's prior rivals, the AFL survived and prospered, in part by signing "NFL rejects" who turned out to be highly talented players
