you can go here and see if it is available over the air in your area. if it is, then you just need an antenna to get it for free.

otherwise you have to swap services to get the channel. my dad has verizon fios and it's on that line-up. but i also can get it free over the air with my antenna at my house.
great channel by the way if you like the old shows.
