 In 1985 , following in the footsteps of Einhorn who had purchased a United States Football League franchise in 1984 , he purchased the Chicago Bulls as part of a syndicate for US $ 16 million and quickly turned the team from one that averaged 6 @,@ 365 fans per game at the 17 @,@ 339 @-@ seat Chicago Stadium in 1985 into one with an 8 @,@ 000 @-@ person season ticket waiting list . He did so by drafting Horace Grant and Scottie Pippen , and trading for Bill Cartwright to join John Paxson and Michael Jordan under the tutelage of head coach Doug Collins . In 1989 , the team signed Phil Jackson as the final piece of the championship puzzle . From November 20 , 1987 through Jordan 's 1999 retirement the Bulls sold out every game .

 The rival American Football League arose in 1960 and challenged the NFL 's dominance . The AFL began in relative obscurity but eventually thrived , with an initial television contract with the ABC network . The AFL 's existence forced the conservative NFL to expand to Dallas and Minnesota in an attempt to destroy the new league . Meanwhile , the AFL introduced many new features to Professional Football in the United States : official time on the scoreboard clock , rather than on a watch in the referee 's pocket , as the NFL did ; optional two @-@ point conversions by pass or run after touchdowns ; names on the jerseys of players ; and several others , including expansion of the role of minority players , actively recruited by the league in contrast to the NFL . The AFL also signed several star college players that had also been drafted by NFL teams . Competition for players heated up in 1965 , when the AFL New York Jets signed rookie Joe Namath to a then @-@ record US $ 437 @,@ 000 contract . A five @-@ year , $ 40 million NBC television contract followed , which helped to sustain the young league . The bidding war for players ended in 1966 , when NFL owners approached the AFL regarding a merger , and the two leagues agreed on one that would take full effect in 1970 . This agreement provided for a common draft that would take place each year , and it instituted an annual World Championship game to be played between the champions of each league . That game began play at the end of the 1966 season . Once the merger was completed , it was no longer a championship game between two leagues , and reverted to the NFL championship game , which came to be known as the Super Bowl .
