I downloaded a software program to my computer that allows me to watch the Buffalo Bills and basically any other NFL game online via live streaming feed. I use it because I'm at work (aargh..) a lot of times when the games are played, and there's no TV at work.

It's easy to operate and downloads very quickly. I like it so much that I watched basically the whole preseason online. The only pc requirements are DSL or cable Internet and a windows operating system (sorry mac users), and it apparently works in any country.
