in 1970 the Chiefs won the AFL Championship and Super Bowl IV (the last Super Bowl played when the AFL was a separate league, prior to it being absorbed into the NFL as the American Football Conference) over the heavily favored Minnesota Vikings. Hunt insisted that he be listed in team media guides as the founder of the Chiefs rather than the owner, and publicly listed his telephone number in the phone book for the rest of his life. Coinage of the term "Super Bowl" In 1966, the NFL and AFL agreed to merge, with a championship game between the two leagues to be played after that season. In a July 25, 1966, letter to NFL commissioner Pete Rozelle, Hunt wrote, "I have kiddingly called it the 'Super Bowl,' which obviously can be improved upon." Hunt would later say the name was likely in his head because his children had been playing with a Super Ball toy. Although the leagues' owners decided on the name "AFL-NFL Championship Game", the media immediately picked up on Hunt's "Super Bowl" name, which would become official beginning with the third annual game in 1969, which was won by the AFL's New York Jets over the NFL's Baltimore Colts. The NASL: ownership and battles with the NFL In 1967 Hunt helped promote professional soccer in the United States. Hunt's interest in soccer began in 1962 when he accompanied his future wife, Norma, to a Shamrock Rovers game in Dublin, Ireland. In 1966, he viewed the FIFA World Cup in England, and then attended nine of the next 11 World Cup tournaments. In 1967, Hunt founded the Dallas Tornado as members of the United Soccer Association. In 1968 the league merged with the National Professional Soccer League to form the North American Soccer League. Hunt was an active advocate for the sport and the league and the Dallas Tornado won the NASL championship in 1971 and were runners-up in 1973. The NFL owners were not happy with Hunt's ownership in and promotion of pro soccer. The NFL attempted to force legal requirements that would disallow team ownership in more than one sport for owners of NFL franchises. This strategy backfired on the NFL, and the NASL won an anti-trust case against the NFL. A primary benefactor of this outcome was Lamar Hunt. In 1981, after 15 seasons and losses in the millions, Hunt and his Dallas
