NFL games are shown locally on OTA TV antennas as well as many different live streaming services. Check your favorite team's page to see your options for streaming it's games online and on your TV.
If the game is on either CBS, NBC, FOX or ABC (which NFL games usually are), you can probably watch it with a inexpensive device called a digital TV antenna. A TV antenna allows you to watch your local broadcast channels for free once you've purchased the antenna. This however requires your home to be within range of the local station that is carrying the game.
While using an over-the-air TV antenna is still the best way to watch NFL most games, especially if you do not live in the "home" area of the team you would like to watch. The NFL has a few official ways to watch your favorite out-of-market teams.
If you want to watch your local teams online via official NFL apps or streaming services such as Hulu Live, Youtube TV or AT&T TV Now, you may need the help of a VPN service to "mask" your location so that you don't get blacked out. VPNs are safe to use and our favorite service is NordVPN.
