- The Arizona Cardinals football team — including its predecessors — is the oldest continuously run professional football franchise in the nation.
- In 1922, the team moved to Chicago and played at Comiskey Park. In that same year, the team joined the NFL as the Chicago Cardinals. The team played there for 37 years.
- Because of The Second World War, the Cardinals combined with the Pittsburgh Steelers to play as one team in 1944. The team was called Card-Pitt.
- In 1988, the Cardinals moved to Arizona and changed their name to the Phoenix Cardinals.
- In their first season as the Cardinals, the team achieved two records: one for single game attendance (vs. Cowboys in their inaugural Arizona game) and one for season attendance.
