I’m looking for things like Amazing Race (all the spin-off countries), Survivor, Gladiators, Ninja Warrior, etc.

If I dip my toe into the Usenet thing, will I find this sort of stuff? Do I have to look in a certain spot? By this I mean do different servers tend to store different styles of catalogues, or do they network like a P2P system?

Apologies if I’m not making sense, I don’t really know the correct jargon.
