Properly inflated, the weigh of an official NFL football is between 14 to 15 ounces (396 to 425 grams).
The official length is 11 inches with the circumference at 22 inches.
The NFL was originally named the American Professional Football Conference when it was founded in 1920.
After one further name change, it wasn’t until 1922 that it got the name that it is now widely known by, the National Football League.
The most popular event in NFL is the Super Bowl of course. It is watched by more than 100 million viewers each year.
A 30 second commercial during the Super Bowl will set you back around 3 million dollars. However, that cost goes up each year.
