Hunt owned the Dallas Texans (now the Kansas City Chiefs), while the Houston Oilers (now the Tennessee Titans) were Adams's franchise.
The AFL quickly became a viable competitor to the established league, in its first year signing half of the NFL's first-round draft choices, and introducing the first professional football gate and TV revenue-sharing plans, which made it financially stable.
The merger was the raison d'être for the first "Professional Football World Championship Games" (later called the Super Bowl), and after losing the first two games of that series to the Green Bay Packers of the elder league, the AFL closed out its ten-year existence with victories over the NFL's best teams after the 1968 (with the Jets upsetting the then-Baltimore Colts) and 1969 (the Chiefs defeating the Vikings) seasons.
After infamously bankrolling The Jackson Five's 1984 Victory Tour, financial difficulties forced Sullivan to sell his ownership stake in the Patriots in 1988 while Foxboro Stadium lapsed into bankruptcy; Sullivan remained team president until 1992 while Robert Kraft purchased the stadium out of bankruptcy to eventually use as leverage to buy the team in 1994.
The Hunt family continues to own the Chiefs, with offspring equally splitting the team, with son Clark the owner of record since Lamar's death in 2006.
