I couldn't say, though they premiered in 2003.
I know they premiered in January 2003, I don't think they are running new episodes at this time but they always have re-runs on! Naked and Afraid is also awesome, have you heard of it?
The Discovery Channel has a lot of interesting shows on, that's why I like to watch it a lot. Oh, did you know that it has the third widest distribution on cable? Damn that's a lot of people that must watch it then. I'm not sure if that's true, but almost 97% of American households have a TV. That's so many people that own TVs but I'm not surprised. I really don't know what my favorite is, honestly. Well, Discovery shows series like Mythbusters, Deadliest Catch and Unsolved History on their flagship channel. I loved MythBusters, but isn't it not on the air anymore?
The series premiered on the Discovery Channel on January 23, 2003.
