The 1920 APFA season was the inaugural season of the American Professional Football League—named the National Football League in 1922. The league was formed on August 20, 1920 by independent professional American football teams from Ohio, all of whom had previously played in the Ohio League or New York Pro Football League. At the meeting, they first called their new league the American Professional Football Conference. A second organizational meeting was held in Canton on September 17, adding more teams to the league. At the meeting, the name of the league become the American Professional Football Association. Four other teams also joined the Association during the year. Meanwhile, Jim Thorpe of the Canton Bulldogs was named the APFA's first president but continued to play for the team.

Scheduling was left up to each team. There were wide variations, both in the overall number of games played and in the number played against other Association members. Thus, no official standings were maintained. In addition, football teams in the APFA also faced independent football teams not associated with the league. For instance, the Rochester Jeffersons played a schedule consisting mostly of local teams from their local sandlot circuit and the NYPFL, not the APFA.

The National Football League has enjoyed success in selling out many of their venues from season ticket sales alone. Out of 32 teams in the league, 24 claim to have waiting lists from under 1,000 people to over 150,000. For some fans, this means a wait not just of years, but decades. This is due mostly to the NFL's short window of play; there are only eight regular-season home games, forcing the most devoted fans into a desperate and sometimes costly search for a limited number of events.

Since 1973, the waiting lists have also had the by-product of preventing any home games of certain teams from being blacked out on local television. Home games must be sold out within 72 hours of kickoff before a telecast is allowed, and the longest waiting lists have ensured every home game of the applicable teams being locally televised. Prior to 1973, home games could not be locally televised even if they were sold out. Four teams have had the benefit of not seeing any blackouts at all since 1972.

Personal Seat Licenses (PSLs) is a license which grants the holder the right to buy season tickets for a particular team. PSLs were first used in the NFL by the expansion Carolina Panthers in 1993 to help finance their new stadium. Since that time, several teams have used the mechanism to finance new stadium projects including the Chicago Bears remodel of Soldier Field and more recently the Dallas Cowboys. The New York Jets and the New York Giants used PSL programs to finance the construction of the New Meadowlands Stadium, now MetLife Stadium.
