Today CBS has a doubleheader. FOX will show one game to each region.
If you live in the New York area, you will see:
Ravens at Steelers late on CBS
The entire nation will see Broncos at Colts tonight on NBC and Vikings at Giants tomorrow on ESPN.
A good chunk of the country outside of the New York area will see today's 1:00 PM kickoff between the Jets and New England. Areas that DO NOT get the game include Western New York, much of the Upper Midwest, most of California, Florida, Houston, Washington DC, Philadelphia, Atlanta, and a few other spots. Most areas not mentioned will get the game shown on CBS.
