That might be interesting. I checked the tv listings here and can't find anything called "How It's Made". I get the "Discovery Channel" - is that the same thing?
George the Science Channel is a spinoff of the Discovery Channel, but they are separate. It's available on DirecTV and Dish if you have the right package, as well as SOME cable systems.
Looks like I'm outa luck. My cable system doesn't carry it. To get the few channels that are worth watching I have to pay for a gazillion useless channels. Oh well.
