For the "Hitchiker's Guide" nerds, in which media was your first exposure?

Inspired by the three boob question.

I first experienced The Hitchhiker’s Guide to the Galaxy through the BBC radio production, and later read the “trilogy” of five books. If you know it, what was your first introduction? Stage, television series, video game, comic book, film? If you’ve experienced it in multiple forms, what was your favorite? (I still love the BBC radio production. I actually bought the set on cassette, but I have no idea where it is now.)

Yes, feeling a little nostalgic tonight.
