I'm not sure if this thread has ever come up before. I searched, and couldn't find it. If it exists somewhere, please feel free to close this thread. 
But the question stands: how were you made aware of Discworld? Who or what made you interested in Discworld to start with?
A long-ago friend gave me his copy of the Discworld video game. I tried it, got stuck, tried again, got stuck, and eventually beat the game. But it made me curious about Ankh-Morpork, Rincewind, Captain Vimes, and the other characters in the game.
So, I went to my local library and, one by one, started reading the Discworld books there (beginning with "Interesting Times", because I was intrigued by the cover ... and also because I recognised Rincewind from the game).
I didn't quite understand everything that was going on (e.g. who was this Arch-chancellor Ridcully?), but I was sufficiently intrigued to want to know more. Especially after the cliff-hanger ending.
So, I tried other books - I think "The Colour of Magic" was my second book, "Guards! Guards!" was the third.
After that, I actively hunted through second-hand bookshops (and eventually new bookshops too) for all Discworld books I could find, put them in order, and started reading from "The Colour of Magic" ... and eventually found the L-Space website.
By this time, Discworld II: Missing Presumed...!? came out, and I found and played it.
Two years later, Discworld Noir (easily the most 'Pratchett-ish' of the Discworld games - i.e. it reminded me so much of the books!) came out, and I snapped it up.
I kept on reading Discworld through the years, but "Discworld Noir" made me curious about noir fashion and noir fiction, but I couldn't find any in my corner of Fourecks ... until, 20 years later, I saw a copy of The Big Sleep in one of my favourite second-hand bookshops. I looked at it, bought it, read it, and quickly tried (and succeeded) in getting a copy of everything else by Raymond Chandler and Dashiell Hammett ... and ... um ... whoops. This is a Discworld thread, isn't it?
Anyway, I've rambled enough. How about you? How did you get into Discworld - and where did it lead you?
