edit: that's the story in the US. I guess FOX owns SKY over there, so they used their own net for that distribution area.
Well technically, they are unrelated. Fox owns little assets over here.
Basically Rupert Murdoch owns BskyB who put out Sky tv, so effectively its all owned by one guy. However, there is independance from Fox although they share the same shows... for example, Fox have just launched their first channel here, called FX, which shows Xfiles... what have you.., that's the Fox channel here
Rupoch Murdoch also owns The Times and The Sun on the newspaper front... scarey actually
