<P> After the NFL's Green Bay Packers won the first two Super Bowls, some team owners feared for the future of the merger . At the time, many doubted the competitiveness of AFL teams compared with their NFL counterparts, though that perception changed when the AFL's New York Jets defeated the NFL's Baltimore Colts in Super Bowl III in Miami . One year later, the AFL's Kansas City Chiefs defeated the NFL's Minnesota Vikings 23--7 in Super Bowl IV in New Orleans, which was the final AFL - NFL World Championship Game played before the merger . Beginning with the 1970 season, the NFL realigned into two conferences; the former AFL teams plus three NFL teams (the Colts, Pittsburgh Steelers, and Cleveland Browns) would constitute the American Football Conference (AFC), while the remaining NFL clubs would form the National Football Conference (NFC). The champions of the two conferences would play each other in the Super Bowl . </P> <P> The winning team receives the Vince Lombardi Trophy, named after the coach of the Green Bay Packers, who won the first two Super Bowl games and three of the five preceding NFL championships in 1961, 1962, and 1965 . Following Lombardi's death in September 1970, the trophy was named the Vince Lombardi Trophy . The first trophy awarded under the new name was presented to the Baltimore Colts following their win in Super Bowl V in Miami . </P> <P> The Super Bowl is currently played on the first Sunday in February . This is due to the current NFL schedule which consists of the opening weekend of the season being held immediately after Labor Day (the first Monday in September), the 17 - week regular season (where teams each play 16 games and have one bye), the first three rounds of the playoffs, and the Super Bowl two weeks after the two Conference Championship Games . This schedule has been in effect since Super Bowl XXXVIII in February 2004 . The date of the Super Bowl can thus be determined from the date of the preceding Labor Day . For example, Labor Day in 2015 occurred on September 7; therefore the next Super Bowl was scheduled exactly five months later on February 7, 2016 . </P> <P> Originally, the game took place in early to mid-January . For Super Bowl I there was only one round of playoffs: the pre-merger NFL and AFL Championship Games . The addition of two playoff rounds (first in 1967 and then in 1978), an increase in regular season games from 14 to 16 (1978), and the establishment of one bye - week per team (1990) have caused the Super Bowl to be played later . Partially offsetting these season - lengthening effects, simultaneous with the addition of two regular season games in 1978, the season was started earlier . Prior to 1978, the season started as late as September 21 . Now, since Labor Day is always the first Monday of September, September 13 is the latest possible date for the first full Sunday set of games (Since 2002, the regular season has started with the Kickoff Game on the first Thursday after Labor Day). The earliest possible season start date is September 7 . </P>
