 While the score was close early on, Vince Lombardi's team held the Browns scoreless in the second half, winning 23–12 in an upset on a Paul Hornung touchdown.After the season, the NFL and the competing American Football League agreed to merge starting in 1970, but would play an inter-league championship from the 1966 season onward.The 1965 championship thus became the NFL's last before the Super Bowl era, which ushered in a new age of popularity and prosperity for professional football.
