Books, telly, radio, films, recommendation?
I'm a little too young to have heard the Hitchikers' radio series first time round but was pretty much exactly the right age for the telly series.
I then forgot all about it until a mate leant me the first h2g2 book several years later. I got hooked and within a year had read pretty much everything he'd had published, bought the radio series on CD and the telly series on VHS. I think that was around about 1991.
How did you come across him?
