Q: Context_1 : The 1957 Brooklyn Dodgers season was overshadowed by Walter O'Malley's threat to move the Dodgers out of Brooklyn if the city did not build him a new stadium in that borough.

The Dodgers final game at Ebbets Field was on September 24 as they finished their 68th and last NL season, and their 75th overall, in Brooklyn in third place with an 8470 record, eleven games behind the NL and World Series Champion Milwaukee Braves.

It lasted until 1970 with the NFL-AFL (third) merger following the establishment of the first "Super Bowl" inter-league national championship game three years before with the old NFL champions playing the victors of the latest rival fourth incarnation of the American Football League IV, formed in 1960 (now the American Football Conference (AFC).
