There are 32 teams in the NFL, split between two conferences (AFC, NFC) and four divisions per conference (AFC North, AFC South, AFC East, AFC West, NFC North, NFC South, NFC East, NFC West).

Most NFL games are broadcast on local and national TV stations in the United States. There are several online streaming services available to watch games for a fee, including Sling, Fubo, and the NFL’s official app.

The Arizona Cardinals and Chicago Bears were part of the NFL in the league’s first season in 1920. The Cardinals, however, existed as a pro football franchise even before the NFL’s existence.

The Cardinals’ history dates back to 1898 when they were based in Chicago and called the Morgan Athletic Club. They eventually became the Cardinals and moved from Chicago to St. Louis to Arizona.

The NFL playoffs consist of four rounds. The first round is known as the wild-card round; the second round is called the divisional round; the third round is the conference championship round, and the fourth and final round is the Super Bowl.

It can be hard to find the NFL game of your choice if you don't have DIRECTV's NFL Sunday Ticket. If you have basic cable, you can watch the games on CBS, FOX, NBC, ESPN, and NFL Network choose to show in your area or on national TV.

Two free alternatives are the official NFL app and the Yahoo! Sports app. NFL games are available to live stream for free on your phone or tablet, but you can only watch games that are being shown in your local market.

The NFL app and Yahoo! Sports app streaming services are not available outside of the United States.
