The Saturday night showing of the first episode picked up 47% of the total TV audience at that time. Top-rated programme, beating some obscure duo called "Ant and Dec" who were claimed to be interviewing some footballer who married one of the Space Girls, or something like that. It does look as though it's been made with the US market in mind. The running time is similar to Star Trek and the way the program is structured they can put in the advertising breaks. Plus the traditionsl use of London landmarks. And 13 episodes made, which is a trifle unusual for a British TV series. If the ratings hold up, I can see it being sold to a US network, not just PBS.
