The Hitchhiker's guide to the galaxy

Part of the multi-media phenomenon The Hitchhiker's Guide to the Galaxy is beloved the world over. Douglas Adams' 'trilogy in five parts' originated as a radio show, developed into a book series, and has since spawned a TV series, a film, additional sequels and expanded radio series, a famously impossible video game, and a number of stage shows. It was a Sunday Times bestseller, and ranked fourth in a 2003 BBC poll to find the Nation's Best-Loved Book.
