Having just re-found it at the bottom of a drawer, this remains one of my favourite non-fiction books.
It's educational, informative, and entertaining (hey, it sounds like the BBC!) and an absolute must-read for anyone who wants to know where UNIX came from, how the C language came about, why both of those things are structured the way they are, and loads of interesting titbits about some of the giants of computer science such as Ken Thompson and Dennis Ritchie.
I don't think the book has ever been officially published in the UK so it can be a bit hard to get hold of over here. It's definitely worth it if you can find a copy, though.
