That’s funny, I swear I remember watching the first series when it first aired on either BBC 1 or 2 (then it got more popular and moved a different channel). Wasn’t BBC 3 only available on Freeview or something? Cos I’m not sure I had Freeview then.
I thought it moved from BBC 1 or 2 to BBC 3 for the second/third series (which was when it became a lot more popular amongst people at school, since that was the ‘in’ channel I guess). I’m probably wrong, but that’s how I remember it.
