The return of the St. Louis Rams to Los Angeles ended a 21-year hiatus during which there was no NFL team in L.A. – the longest period of its kind, when there was an NFL city after the merger, and led St. Louis to be the only NFL city to take over from Los Angeles in 1969 without a current NFL team. Since the Colts changed the 1983 season, the NFL has not simultaneously established teams in the 16 markets of 1969. He had teams in the 1969 AFL Cities of the 2002 season (when the Texans entered the league) until the end of the 2016 season (when the Chargers returned to Los Angeles, so San Diego without an NFL team). In the spring, a series of secret meetings were held on a possible merger between the AFL and the NFL between Hunt of Kansas City and Tex Schramm of Dallas. Rozelle announced the merger on June 8. The agreement provides that the two leagues will form an expanded 24-team league, which is expected to be increased to 26 and 1970 in 1968, or to 28 shortly thereafter. All existing deductibles would be maintained and no deductibles would be transferred outside their metropolitan areas. While they maintained separate game plans until 1969, the leagues agreed to play from January 1967 an annual AFL-NFL world championship and hold a combined project that also began in 1967. The pre-season takes place from 1967 between the teams of each league.
The official broadcast season would begin in 1970, when the two leagues would officially merge into a league with two conferences. Rozelle was appointed commissioner of the league`s expanded configuration. With the merger, the Super Bowl became an NFL championship game. In the first four, the loyalty of fans, whose teams were not clear in the game, as by the hundreds of Buffalo Bills fans who met the New York Jets at Buffalo Airport for their first post-Super Bowl III visit to play the Bills, and standing ovations that received the Jets in opposing stadiums in other former AFL cities. Although the Super Bowl is now one of the biggest one-day sporting events in the world, the intense rivalry between the leagues no longer exists. Although Pete Rozelle did not begin negotiations on the merger, he quickly accepted the deal and remained as NFL commissioner. Although he was not formally invested in a new title (s) in the four years following the merger agreement, Rozelle has often been referred to as a commissioner responsible for football in the media. The position of president of the NFL, which already existed, remained unchanged as a result of the agreement. The presidency of the NFL, then occupied by Cleveland owner Brown Art Modell, was essentially (before and after the merger agreement) an honorary title that functioned in the same way as the presidencies of the MLB league in the 21st century.
Contrary to popular belief, it was not the AFL, but the NFL that initiated discussions on merging the two leagues, fearing that Davis` “not taking prisoners” tactics would seriously reduce the older league`s profitability and/or drastically reduce its talent base. Tex Schramm, general manager of the Dallas Cowboys in the NFL since 1960, secretly contacted the owners of the AFL under the direction of Lamar Hunt of Kansas City and asked them if they were interested in a merger.  The discussions took place without the knowledge of Davis, the new commissioner of the AFL.  On the evening of June 8, 1966, New York employees announced a merger treaty.     As part of the agreement, the NFL Players Association and the NFL Management Council ratified a collective agreement that smoldered five seasons of football, while maintaining the retirement plan, including the years 1974, 1975 and 1976, with contributions totalling more than $55 million.
